Watch what is the "Shock-trigger mechanism" in other dictionaries. Trigger of the crossbow
Devices for breaking the cartridge capsule (cartridge case) when fired from a firearm. Shock mechanisms of artillery pieces are usually part of the shutters. According to the principle of action, the impact mechanisms are hammer and hammer.
In the impact mechanisms (Figure 1), when cocked, the drummer is pulled back by the platoon and the fighting spring contracts. When lowering under the action of the fighting spring, the striker strikes the blows with the capsule or the bottom of the capsule sleeve, then either immediately retreats or is cocked just before the opening of the bolt. Shock mechanisms of this type are simple in design and are widely used in wedge gates of semi-automatic and automatic guns. In the percussion mechanism of the piston gates of nonautomatic guns, there is also a cocking device (trigger). 
Hammer type impact mechanism (Figure 2) consists of a spring-loaded striker, a hammer with an axle, a piston with a rail and a fighting spring. When cocked, the hammer is pulled by a cord and gets rotated by moving the piston rod and thereby compressing the fighting spring. When lowering under the action of a war spring, the hammer rotates in the opposite direction, strikes the striker, which breaks the capsule. Hammer impact mechanisms are most often used in piston locks of large-caliber guns.
The impact mechanisms of small arms are divided into hammer and trigger. The hammers are used in non-automatic shop rifles (carbines) and some submachine guns of the Second World War, hammer ones in many modern guns, pistols and hunting rifles. In shock mechanisms of the first type, the fighting spring acts directly on the drummer, in the second-type impact mechanisms - through the trigger. The trigger-type impactor mechanism is usually part of the trigger mechanism of the automatic weapon sample. For example, the shock-trigger mechanism of the Soviet 7.62 mm AKM automatic machine, in addition to striking a striker (trigger with a battle spring), also serves to lower the trigger from the combat platoon or from the self-timer cocking (trigger), to provide automatic (self-timer) or single fire (whispering of a single fire), slowing the trigger forward to improve the accuracy of combat with automatic fire (trigger delay), preventing a shot with the unlocked shutter (self-timer) and setting the gun to automatic (single) fire or fuse (translator). Shock-trigger mechanisms of pistols and hunting rifles provide, as a rule, only a single fire.
SHOCK MECHANISMS
DEPENDING on the type of energy reported to the ignition device (primer, electric plug, electric cup) for the production of a shot, distinguish between mechanisms of mechanical action and the electro-trigger mechanism. In automatic weapons, shooting mechanisms are called shock-triggered. The purpose of the shock-trigger mechanism is to ignite the cartridge capsules in the production of a shot that is in the barrel chamber, when the needle is triggered by the trigger element (descent). Since constructively they are often performed in the form of separate units (shock and trigger), it is advisable to consider the device of shock and trigger mechanisms separately.
The impact mechanism must satisfy the following basic requirements: reliable ignition of the capsule; no breakthrough of powder gases through the primer; sufficient survivability of the striker; the exclusion of the production of a shot when the shutter is not closed; Exclusion of the priming of the capsule due to the inertia of the impactor when the shutter is closed.
The main elements of the impact mechanisms are: a drummer or trigger, which is informed of the specific kinetic energy necessary to ignite the capsule, and a pincher, which serves to directly affect the capsule (impact by the primer). The impact mechanism is driven by a pre-compressed spring. If the impact mechanism has a separate spring, which serves exclusively to impart energy to the striker, then such a spring is called a combat spring (for example, in a PM pistol, an automatic machine and a Kalashnikov machine gun, a SCS carbine). If the impactor is informed of energy from the return spring, then such a spring is called a return-fighting spring (for example, in the manual machine gun of the DP, machine gun SGMT, a single machine gun of PC / PCMT, large-caliber machine guns DKhKM and KVVT).
Drummer - the detail of the impact mechanism, which transfers kinetic energy to the striker. Directly strikes blow on the capsule of the firing pin or the element of the drummer.
A striker is a detail of the impact mechanism, directly acting on the primer to ignite it. The diameter of the striker along its diameter and its shape (for example, oval or round) affect the fail-safe ignition of the cartridge capsule and vitality. In practice, the greatest distribution was received by pins of round shape. There are samples of weapons that have an oval form of a striker.
The trigger is the detail of the trigger hammer mechanism that transmits the energy of the fighting spring to the hammer.
The impact mechanism is held in the cocked state by the trigger piece - the whisper. The area on the drummer or the hammer on which the whisper rests while holding the impact mechanism in the cocked state is called a combat platoon. The fighting spring can act on the trigger or directly on the hammer.
Shock mechanisms, depending on the energy of which spring is used to bring them into action, are divided into two types:
1. Shock mechanisms operating from a battle spring, which in turn, depending on the nature of the movement of the part, which is reported kinetic energy for ignition of the cartridge capsule, are divided into hammer and hammer. The impact mechanism, in which the fighting spring acts directly on the striker, which performs rectilinear and translational motion, is called the impactor.
In the trigger mechanism, the energy of the combat spring is perceived by the trigger, which makes a rotational movement around the axis, and is transmitted by hitting the striker or striker.
2. Shock mechanisms operating from a return-fighting spring differ substantially from impact mechanisms operating from a special battle spring. In these impact mechanisms, the role of the impactors or the hammers is performed by closures or gate frames. The spring, which returns the moving parts of the automatics to the initial position, the energy of which simultaneously serves to activate the impact mechanism, is called the return-combat.
The expediency of using different types of impact mechanisms is mainly determined by the design of the remaining mechanisms and their overall layout, as well as some specific requirements for weapons.
IMPACT MECHANISMS WORKING FROM THE BOILING SPRING
The impactor mechanism is a shock mechanism in which all the parts that transmit the energy of impact are placed in the bolt and / or on the shutter frame and accompany the bolt and / or the shutter frame in their movement. In the impact (shock) mechanism, the main parts are usually the drummer and the fighting spring. In striker mechanisms, the drummer is most often connected with the striker during movement and rarely is not connected. Shock mechanisms are used in machine guns SSMT, PC, PKT, DShKM, KPVT, etc. In these mechanisms the shutter frame (in the machine gun KPVT - shutter) serves as a trigger. At the same time, the priming of the capsule can occur due to the inertia of the impactor, which previously moves with the bolt frame (a single Kalashnikov machine gun, PC / PCM). In the machine gun KPVT the drummer is activated by a bolt. The striker hammer can be made as one piece with the drummer or (for a quick replacement in case of breakage) are connected to the drummer by a fixed connection, and can also be carried out separately. The use of the shock mechanism of the striker type with a separate striker with a large stroke of the striker allows to significantly reduce the rate of fire of the automatic weapon due to the additional time of movement of the striker.
According to the method of cocking the striker, the impact mechanisms operating from the fighting spring are divided into mechanisms with cocking the hammer when the bolt moves forward, with the bolt moving backwards and the combined type. An example of the impact mechanism with the charging of the impactor when the shutter moves backwards is the mechanism of the machine gun "Maxim" arr. 1910, and the impact mechanism of the machine gun MG.17 is an example of a shock mechanism with the firing of a drummer with the movement of the bolt forward. The most reliable in operation is the first type, which is widely used. The reliability of the operation of this mechanism is ensured by the fact that for the cocking of the fighting spring the gate movement is used, in which it has the greatest kinetic energy reserve.
In the pistols only shock mechanisms operating from the fighting spring are used. This type of shock mechanism is most suitable mainly for self-loading and automatic rifles, as they provide the cocked position of the drummer (or trigger) when the bolt is closed and reduce the time from the moment the trigger is pressed to the shot.
At the same time, impact mechanisms may not have an independent fighting spring. In this case, the striker or the drummer receives energy from the leading link of the automation at the end of his retreat (Thompson submachine gun, SGM machine gun).
In non-automatic weapons, sometimes the drumming is carried out in combination. For example, in a rifle rifle arr. 1891/30 years, the firing of the drummer occurs when the bolt is unlocked, i.e. when the stem of the bolt is rotated and when the final stalk of the shutter is forwarded. Combined cocking the drummer is sometimes used in automatic weapons.
The trigger mechanism is a shock mechanism in which certain parts, including a trigger with a fighting spring, are placed outside the shutter and do not accompany the bolt and the bolt frame in their movement. This design provides the following advantages: simplicity of manufacturing and installation of the mobile connection; low friction losses; when cocked, the trigger can be moved beyond the limits of the action of the moving parts of the automation.
In the trigger hammer mechanism, the main parts are the hammer, the trigger and the fighting spring. In modern automatic weapons, as a rule, the trigger is not connected to the striker, usually the trigger strikes the striker. Although in non-automatic weapons, the punch in the trigger mechanism can be made as one with the trigger (in English.38 revolver N2 Mk II). In the national revolver "Nagan" arr. In 1895, the firing pin was installed in the trigger on the axis, providing some of its swing, which makes it quite easy to center it on the capsule with the help of a hole in the frame of the revolver.
The trigger mechanism is used in pistols, a carbine SCS, a machine gun and a Kalashnikov machine gun. The use of hammer impact mechanisms makes it possible to exclude the influence of movement and impacts of moving parts on the accuracy of aiming and firing. The use of a percussion mechanism with an open-type trigger in the submachine gun makes it easy to cock the machine after a misfire, and also indicates the position of the trigger (cocked or not cocked), which is important for ensuring the safety of handling weapons.
In the hammer mechanism, the drummer may be absent, and the trigger strikes directly at the hammer (homing hunting rifles). If, at the same time, the trigger is adapted for external cocking, then it must have a retreat - a certain course backwards with subsequent installation on the fuse in order to avoid an accidental shot with accidental mechanical action on the trigger.
IMPACT MECHANISMS OPERATING FROM THE RETURN-BREAK SPRING
Shock mechanisms operating from the return-fighting spring are widely used in submachine guns, hand, machine guns and large-caliber machine guns. For example, submachine guns Shpagin PPSh and Sudayev PPS, manual machine gun DP, machine gun machine Goryunova SGM, machine gun DShK and aircraft machine SHKAS have impact mechanisms of this kind. Shock mechanisms operating from the return-fighting spring are characterized by the following features: a) they have a large supply of energy for breaking the capsule; b) the impact mechanism is on the combat platoon with the rear position of the moving system, while in the chamber there is no cartridge, which promotes rapid cooling of the barrel during short breaks in the shooting; c) the simplest design of the impact mechanism is possible, especially in systems with the removal of powder gases (this feature is fully used in domestic weapons samples).
SPASK MECHANISMS
The trigger is a set of parts that provide control of the beginning and end of the shooting, and is designed to reliably hold the trigger, hammer, bolt or bolt frame in the cocked position before the shot and their rapid release when firing at the trigger element (release).
Triggers used in non-automatic weapons have a simple device, which essentially depends on the device of the impact mechanism and the overall arrangement of all weapons mechanisms.
Depending on the type of shooting, the triggers of automatic weapons are divided into three types: mechanisms that allow only automatic (continuous) shooting; mechanisms that allow firing only single shots; Combined fire mechanisms that allow single and continuous firing.
The main elements of any triggering mechanism are:
- whisper - the part that serves to hold the impact mechanism (PM pistol, AKM / AK-74 assault rifle, SCS carbine) or the mobile system (machine guns SGMT, PKM, KPVT, etc.) in the cocked position and directly interacting with the combat platoon - a drummer, a hammer, a bolt, or a bolt-action frame, into which the whisper rests, holding these parts in the cocked position;
- trigger (at the KVVT machine gun - trigger lever) - a piece that controls the operation of the sear for the production of a shot directly or through a system of levers and perceives the pressing force from the arrow;
- springs, which serve to return the trigger parts to the starting position.
Depending on the specific design scheme of the shock and locking mechanisms, the principle of operation of automatic weapons and the type of trigger itself, the following additional mechanisms and devices can be introduced into its design: uncouplers, fire translators, automatic descents, fuses, retarders of the rate of fire, etc. (for example, the body is in a sniper rifle of an SVD, the trigger retarder is in the AKM / AK-74 automatic rifle).
The disassembler is a part temporarily disrupting the connection between the trigger or other trigger piece and the whisper to ensure that the shock mechanism stops in the cocked position when the trigger trigger is pressed. Separator is available only in the triggers of weapons intended for single firing (AKM / AK-74 assault rifle, SCS carbine).
The fire interpreter is a detail, when exposed to which the type of fire changes (single fire to continuous or vice versa).
Self-timer - a part that automatically releases the trigger (in the AKM / AK-74 automatic machine and the RPK / RPK-74 hand machine gun) or a drummer to produce a shot while conducting continuous shooting.
Triggers, depending on the type of descent, are divided into hook, button and lever. Hook trigger mechanisms, i.e. having a trigger, are widely used in all types of hand weapons. Lever and button triggers are used mainly for machine guns.
AKM / AK-74 submachine guns and RPK / RPK-74 machine guns, RPG-2 and RPG-7 grenade launchers, SCS rifle and SVD rifle and trigger are structurally combined and are called shock-trigger mechanisms.
In pistols, there are also combined mechanisms, but they are called self-cocking trigger mechanisms, i.e. with devices that enable you to cock the trigger or the drummer when you pull the trigger. For example. in the trigger mechanism of the PM pistol to ensure this, a special piece is fixed on the pull rod, which, when the trigger is pressed, enters the notch of the trigger and rotates it, cocking the fighting spring until the trigger is released from it by a certain rotation of this part.
In machine guns intended only for conducting continuous fire, the trigger and impact mechanisms are executed separately.
In the SVD rifle, SGMT, KPVT and NSV machine guns, the trigger mechanism is arranged in a separate housing. Such a design of the trigger mechanism provides access to it during maintenance and repair, since it separates not the individual parts, but the entire mechanism assembly.
The triggers of the KPVT and NSV machine guns are located on top of the receiver, in the remaining weapons, the triggers are located in the lower part of the receiver. A special feature of the KPVT trigger mechanism is the presence of a detachment device designed to exclude the biting of the searches of the sear and the projections of the combat cocking of the shutter with the slow release of the trigger when shooting ceases.
In many machine guns, submachine guns and hand-machine guns, combined trigger mechanisms are used that allow single-fire and fire bursts. These mechanisms are usually performed with a fire translator. An example of a combined trigger mechanism is the trigger mechanism of the Kalashnikov assault rifle.
Combined triggers without a uncoupler can be of two types: with two triggers and with a double trigger. An example of a combined trigger with two triggers is the trigger of the French manual machine gun Shaterro M 1924/29. In this mechanism, both triggers act on one sear. When you press the front trigger trigger, the trigger is detached from the sear, by releasing the trigger dog from the sear. The back trigger with the sear, form the usual scheme of the trigger for the fire bursts (when the impactor is operating from the return spring).
The trigger without a double-triggered translator is used, for example, in the German single MG.34 machine gun. In this mechanism, the change in the type of fire is based on a different turn of the trigger, which is made double. On the lower part of the trigger there is a lever that, when pressed, allows the trigger to be pulled further than when pressing the upper part of the trigger. This provides different angles of rotation of the trigger for different types of fire.
SPECIAL DEVICES OF SUSPENSION MECHANISMS
Depending on the type of weapon and its purpose, additional details and devices can be included in the design of the triggers, which improve their operation and increase the reliability. For example, in the designs of impact mechanisms, there are necessarily fuses, which ensure that the trigger of the trigger is uncoupled from the trigger of the trigger only after the gate channel is completely blocked by the bolt (this is usually done by the self-timer).
There are also fuses, which exclude the possibility of an accidental shot. They are activated by the shooter. Depending on the nature of the impact of the arrow on the fuses, there are two types: non-automatic fuses, switched on and off directly by the arrow moving the button or turning the flag (PPSH submachine gun, single machine gun PC / PCM); automatic fuses, which are activated regardless of the arrow (most often due to the spring force of the springs), but are switched off by the shooter in preparation for the shot before aiming by moving the button or by turning the lever with his hand (hunting rifles), or with the butt of the butt of the butt (manual machine gun DP) , pistol grip (pistol "Colt" M 1911A1, submachine gun "Uzi").
All fuses of this type provide a rupture of the kinematic connection between the sear and the trigger, and sometimes further impairs mobility and the drummer (in PM pistols, APS). This is achieved by locking or shutting down the main part of the trigger (whisper, trigger). In modern models of automatic weapons, due to high reliability, fuses with rigid locking of the sear are the most common.
Structurally, the safety device consists of the fuse itself, the control button or the flag, the retainer and the springs. If the fuse during the installation in the protection position moves at the moment of locking or deactivation, it is then operated in this case most often by a button and is therefore called a pushbutton, and if it is set to the protection position, it is rotated by the flag-flag.
ELECTROPASK MECHANISMS
The electrospun mechanism is a mechanism whose functioning is associated with the use of electrical energy. The electroslash is designed for remote (at a distance) control of the operation of the trigger mechanism of the machine gun.
Machine guns with electric releases, as a rule, are used in tanks or airplanes (helicopters). Electrospuns are separated from machine guns during maintenance and repair.
From machine guns SGMT, PKT and KPVT shooting is conducted only by means of electrospells, therefore they are used only in armored vehicles. Machine guns GSHG-7.62 and YakB-12.7 - are used in helicopters. The NSVT large-caliber machine gun is universal, as it has a manual trigger mechanism and a detachable electric release.
The use of the electrospray improves the possibility of using a machine gun. For a manual (mechanical) trigger, the time of descent is 0.11-0.18 s, for the electromagnetic trigger mechanism - 0.07-0.09 s, and for the electric trigger mechanism - 0.005-0.006 s. Even more obvious is the comparison of the response time of the impact mechanism, which makes 0.006-0.01 s for a mechanical shock mechanism, and for the electro-scalding the response time is taken to be "0". The advantage of the electrospinning mechanism is also the protection of the mechanism from contamination and mechanical damage. The disadvantages of the electrospray include the complexity of the design and more labor-intensive repairs in comparison with the mechanical trigger. Electrospunks of machine guns PKT and SGMT are similar in design, many details of these electric starts have full interchangeability. They differ only in the way of attachment to the receiver: in the PKT machine gun, the electrospin is fixed in the vertical grooves of the butt plate, and in the SGMT machine gun - in the detachable otternik.
Despite the difference in the device of electric releases, the basis of the design of any of them is an electromagnet, inside which the anchor is placed with a pusher. Electric current to the electromagnet is supplied by means of an armored cable from the electrical equipment of the combat vehicle (generator, accumulators). When the current passes through the windings of the electromagnet, the magnetic field interacts with the armature, which begins to move under the influence of the magnetic attraction force. The force of the moving armature through the pusher is transferred to the system of levers, thus ensuring the removal of the bolt frame, the shutter of the machine gun from the combat platoon of the sear. The greatest efficiency of an electromagnet is achieved due to the minimum value of the residual part of the working air gap, i.e., the gap that remains after retraction of the armature. However, with an excessively small gap due to residual magnetism, it is possible to stick the anchor when returning it to its original position. One way to avoid sticking anchors is the placement between the armature and the abutment of diamagnetic spacers, which provide a fixed value for the residual gap and protection against sticking of the core with the armature when the winding is de-energized.

Mechanical igniting devices (according to GOST in small arms they are called impact mechanisms). The creation of mechanical igniting devices was objectively possible after the invention of inflammable formulations (called initiators), sensitive to mechanical impact-shock.
The first lock, where the ignition was due to a trigger strike on the initiating compound, was patented in 1807. Hazardous mercury was used as the initiating substance. Approximately at the same time, the first capsules appeared - cakes of initiating composition, placed between two waxed pieces of paper, protecting it from dampness.
To date, there are four basic types of shock mechanisms (Figure 5). Forensics. Textbook. Ed. I. F. Krylov. - St. Petersburg, 2001 - 256 sec .:
Fig. 5. Constructive types of impact mechanisms:
a - the shock; b - homing; c - curled-hammer; d - bolt (1 - peg, 2 - hammer, 3 - trigger, 4 - bolt)
Impact. The impact on the capsule is applied by the drummer, which is a longitudinal-sliding rod, located in a special channel inside the shutter. The front of the drummer is called the striker (Parabellum, TC, Browning sample 1906, 1910 gg.).
Quarking. The impact on the capsule is applied by the trigger, which rotates about the axis perpendicular to the channel of the barrel, on which the striker is rigidly or mobilely fixed. For example, Nagan's revolver, some models of hunting rifles, mostly with an internal trigger. The bells can be returnable (inertial action), which, after hitting the capsule, go back and stand on the safety platoon, as well as the non-return ones, remaining in the forward position after the impact.
Curk-and-strike. The hammer and drummer are separately included in the design of the weapon. The capsule is broken by the impactor, which is triggered by the trigger. This is the most common design of the shock mechanism. The trigger can be located openly (PM, Walter, Beretta) or hidden (Browning sample 1903, AKM, SVD, etc.).
Shutter. The boom is made in the form of a protrusion on the cartridge stop of the bolt. The cap splits when the barrel bore is locked. This scheme is typical for submachine guns (PPSh, PPS, Uzi, PP-90, etc.)
The trigger of a firearm generally provides control over the beginning and end of the shooting.
The trigger and impact mechanism function in close interaction, so these mechanisms are often considered as a single mechanism and are called the trigger mechanism (USM).
Triggers, which provide only the descent of a pre-cocked cock from a combat platoon, are called single-action mechanisms. Triggers that provide, in addition, and cocking the trigger when you press the trigger (self-cocking), are called triggers of double action. In this case, individual models of weapons and often homemade weapons allow only shooting self-cocking.
The main details of the trigger mechanism are: trigger, trigger pull, whisper.
In automatic weapons for the implementation of single-fire mode, the trigger mechanism includes a so-called separation mechanism.
The mechanism of separation makes it possible to set and hold the trigger or the drummer on the combat platoon with the trigger trigger pressed during the reloading of the weapon. This is achieved by:
1. Disconnection of the trigger or trigger pull with the sear (fig. 6.) when the shutter moves back (almost all automatic pistols, SVD, etc.).
2. Intercept the trigger in its rear position with a single-fire whisper (AK family, PKK and A-91).
Fig. 6. The device of the trigger of the automatic weapon:
1 - the trigger; 2 - the spring of the uncoupler, 3 - the sear; 4 - the fighting spring; 5 - trigger; 6 - the drummer; 7 - the shutter; 8 - uncoupler
For a new shot after reloading it is necessary to release the trigger, thereby restoring the chain: the trigger is whispered, and again press it.
The amount of force applied to the trigger for the production of a shot is normalized for each weapon model and must be within certain limits. For example, the revolver Nagana 3.6 - 5kg, TT 2 - 5kg, AKM 1.5 - 2.5kg, etc.
They asked about the trigger mechanism. I decided to make a separate article on this issue.
Let's consider how the trigger of the crossbow works.
Externally, the crossbow looks like this:
The appearance of the crossbow
The trigger mechanism of the crossbow is painfully simple. Its purpose is to make the descent smooth and easy. The smooth and easy descent of the bowstring is the key to getting into the goal.
The proposed trigger mechanism is not only easy to manufacture, but also long-lasting. In doing so, it allows the trigger to automatically return to its original position.
It looks simple. The log of the crossbow is cut into two parts, that would be placed between them the mechanism of descent. We cut out two steel or brass plates. They should be the same, in the figure they are indicated in purple. They can be made in various forms, the main thing is that they fulfill their role. We fasten two pieces of the bed and hold the mechanism.
The device of the trigger of the crossbow
The drum holds the bowstring. The trigger holds the drum. Once the trigger is pressed, the drum is released from the obstruction and starts to rotate. Bowstring flies from the drum, and the arrow goes to the target.
Drum with a boom
After the shot is fired, we pull the bowstring back, while the drum is engaged with the ledge by the ledge and turns to the starting position. Here the trigger spring works, and the trigger rises into the groove of the drum. Everything, the drum again is rigidly fixed and does not rotate. We put the string on the hooks of the drum and that's it. The crossbow is ready for a new shot.
