SUBSTANCE: system of locking of a stock channel with small recoil impulse has top and lower locks with identical weight, with two stops on the left and on the right side on each lock, kinematically connected by two levers of the same length with a rotation axis in the middle of levers. One lever connects the left stops, and the second one - the right stops. Each lock has ledges and gear racks which are connected among themselves by the synchronizing gear wheel. When using powerful ammunition in the place of impact of ledges on the locks the shock-absorbing device can be installed.

EFFECT: decrease of recoil during firing and improvement of firing efficiency.

Description

The invention relates to weapons technology and can be used to lock the barrel in small arms. The purpose of the invention is the reduction of the recoil momentum during the shot.

The famous Glock-17C pistol. [Pilyugin V.I. Pistols and revolvers: selection, design, operation / V.I. Pilyugin, M.B. Ingerlab. - M .: ACT: Astrel, 2010. - P.78].

Pistols of this modification are equipped with a built-in compensator made in the form of several upward directed holes located at different intervals in the muzzle of the barrel, and an elongated cutout in the upper part of the shutter housing. The presence of this device allowed to reduce recoil when fired and increase the accuracy of fire. The disadvantage of this design is the reduction in bullet speed.

The prototype of the invention is a gun I.Ya. Stechkina APS [Murakhovsky V.I., Fedoseev S.L. Weapons of infantry. - M .: Arsenal-Press, 1997. - P.73-74]. Automation APS operates due to the release of a free shutter. The disadvantage of this gun is: high returns, especially when firing in bursts, which leads to the need to use a holster-butt.

The technical result when using the invention is:

- reduced recoil when firing;

- improving the accuracy of shooting;

- the ability to fire bursts with one hand without using a shoulder rest;

- the ability to use powerful ammunition when shooting with one hand.

The technical result when using this invention leads to a significant decrease in the recoil momentum during the shot due to the fact that the recoil momentum during the shot due to the design features is divided into two oppositely directed flows of kinetic energy:

- the first recoil impulse when firing occurs due to the pressure of the powder gases on the mirror of the upper shutter and is directed backward;

- the second stream of kinetic energy of the lower shutter, created using two levers, is directed forward, in the direction of movement of the bullet;

- when moving, the upper and lower shutter collide with their protrusions and quench the kinetic energy of each, since their motion vectors are opposite, and each mass and speed are the same.

The technical result is achieved through the use of two valves of the same mass, the upper and lower with two stops on the left and right on each valve, kinematically connected by two levers of the same length with the axis of rotation in the middle of the levers, with one lever connecting the left stops and the second lever connecting the right stops, Each bolt has protrusions and gear racks, which are interconnected by a synchronizing gear.

When using powerful ammunition (for example, in air guns), a shock-absorbing device must be installed in the place where the protrusions on the bolts collide.

Figure 1 shows a General view of the locking system of the barrel with a small recoil momentum when firing.

There is a frame 1, an upper shutter 2, on which there are stops 3 and a protrusion at the bottom left and right 4. The lower shutter 5 also has two stops 3 at the left and right and a protrusion 4 at the top. The stops 3 on the upper shutter 2 and the stops 3 on the lower shutter 5 are in contact with two levers 6 of the same length. One lever 6 is located on the frame of the gun 1 on the right side, and the other lever 6 is on the left side. Both levers 6 are fixed on the frame 1 of the gun axis 7 and can be rotated. The return spring of the levers 6 is not shown in the drawing.

Figure 2 shows a General view of the locking system in the position of the rollback of the upper shutter 2 back.

There is a pistol frame 1, an upper bolt 2 with an emphasis 3 and a protrusion 4 at the bottom, a lower bolt 5 with an emphasis 3 and a protrusion 4 at the top. The distance between the protrusions should ensure the movement of the upper shutter, so that the cartridge is ejected and the cartridge is sent from the magazine to the chamber. The rotary levers 6 on the axis 7 are installed in the frame of the gun 1.

Figure 3 shows the cutout of the individual parts of the shutter: the protrusion 4 of the upper shutter 2 and the protrusion 4 of the lower shutter 5, the gear rack 9 on the upper shutter 2, the gear rack 9 on the lower shutter 5. The rotation axis 7 of the levers 6 and the synchronizing gear 8, dressed on axis 7.

The mass of the upper shutter 2 (150 g) and the lower shutter 5 (150 g) are equal in total to the mass of the shutter of the prototype (300 g).

The shoulder of the upper and lower parts of the levers 6 relative to the axis of rotation 7 to the stops 3 on the upper 2 and lower 5 shutters should be the same (see Figure 1).

We take up a weapon in our hands, insert a magazine with cartridges and move the upper shutter 2 back. At the same time, the return spring of the shutter 2 is compressed. The shutter 2 moves back along the guides in the frame of the gun 1 from the influence of the efforts of the hand, and the return spring of the shutter 2 is compressed and the cock is cocked. The movement is carried out until the upper shutter 2 and the lower shutter 5 with their protrusions 4 are not in contact (Figure 3). In this case, the levers 6, located on the frame of the gun 1 and fixed by the axis 7 together with the synchronizing gear 8 (Figure 1), rotate and move the lower shutter 5 forward.

We release the upper shutter 2. At the same time, its return spring moves the shutter 2 forward. A cartridge is removed from the magazine and sent to the chamber. The gear rack 9 of the upper shutter 2, which is meshed with the gear 8, gives it a rotation, which in turn transfers force to the gear rack 9 of the lower shutter 5 and forces the lower shutter 5 to move back. At the same time, two levers 6 on the axis 7, located on the right and left on the frame of the gun 1, the force of the return spring (not shown) is returned to its original position. The cartridge is in the chamber, the cock is cocked, the gun is ready to fire.

When you press the trigger, the striker destroys the capsule of the cartridge due to ignition and combustion of the powder, the pressure of the powder gases in the chamber rises. This pressure takes the upper shutter 2, but the shutter 2 is held in front position by two levers 6, which are in contact with the stops 3 of the upper shutter 2.

However, the upper shutter 2 along its guides begins to move backward, compress the return spring of the shutter and rotate the levers 6 with its stops. At the same time, the lower ends of the levers 6, which are in contact with the stops 3 of the lower shutter 5, will move with acceleration: the lower shutter 5 forward and upper shutter 2 back. The gear rack 9 of the upper shutter 2 and the gear rack 9 of the lower shutter 5 will rotate the gear 8 on the axis 7, which synchronizes the movement of the upper shutter 2 and the lower shutter 5. In this case, the gear 8 rotates on the axis 7 and does not absorb dynamic forces from the action of powder gases , and only after the shot returns the lower shutter 5 to its original position by the force of the return spring of the upper shutter. The accelerated movement of the lower shutter 2 forward is carried out by the force of levers 6 on the axis 7 from the pressure of the powder gases. Shutters 2 and 5 receive significant kinetic energy, move towards each other, collide with their protrusions 4, and the kinetic energy of each shutter is absorbed.

Since the bolts 2 and 5 are in collision with each other, the upper bolt 2 in the rear extreme position eliminates the blow into the frame of the gun 1, which leads to a significant reduction in recoil.

After the shot, the return spring of the upper shutter 2 moves the shutter forward, the toothed rack 9 of the shutter 2 rotates the gear 8 on the axis 7 and the lower shutter 5 also returns to its original position. The stops 3 of the lower shutter 5 touch the lower ends of the levers 6 and are locked by the upper 2 and lower 5 shutters. The gun is ready to fire again.
