Description

The invention belongs to the technology of weapons, in particular to the locking mechanisms of automatic weapons, and can be used in weapons for the army and law enforcement agencies.

A shooting system is known, which contains a receiver with combat protrusions, a bolt frame with a bolt, locking elements - combat stops, installed with the possibility of interaction with the receiver and bolt and a limited tilt, a barrel, a gas piston, a gas chamber riser with a gas chamber installed on barrel, a gas tube installed on the riser of the gas chamber, a shock-trigger mechanism containing a trigger or striker, while in the front part of the bolt there are combat protrusions made with the possibility of interaction with combat stops.

Locking elements - combat stops formed on the locking keys, while at least one locking key with front and rear combat stops is installed on the outside of the side, lower or upper surface of the receiver with the possibility of tilting when interacting with the bolt frame. On the side, upper or lower wall of the receiver, at least one combat stop is made with the possibility of interaction with the rear combat stop of the locking key. The shutter has at least one combat stop designed to interact with the front combat stop of the locking key. The barrel is installed in the rear part of the receiver, directed to the muzzle of the barrel. The riser of the gas chamber in the upper part has a through longitudinal hole. The rear end of the gas tube is installed in the front part of the receiver without the possibility of longitudinal movement, and the front end is inserted into the through hole of the gas outlet riser. The front end of the gas tube is closed and forms a gas chamber with a side gas discharge hole that coincides with the gas discharge hole of the riser of the gas chamber OA Mo 101693 С2, 410 7/00, 2012, ии VO Mo 2488064 С2, P416 7/00, GATA 3/36, EATA 5/18, 20131.

The disadvantage of this rifle system is that a shutter frame is required to close the barrel, and it is quite heavy, difficult to manufacture, and has large dimensions, which leads to an increase in the dimensions and weight of the weapon.

The invention is based on the task of improving the design of the locking mechanism of automatic weapons as a whole, as well as its individual parts and mechanisms, to increase the operational characteristics to increase the reliability of locking automatic weapons, to reduce its dimensions and weight, and to simplify manufacturing.

The problem is solved by the fact that in the automatic weapon locking mechanism, which

Zo contains a receiver with a barrel and combat protrusions, combat stops in the form of locking keys installed on the receiver, a shutter frame with a shutter, in the front part of which there are combat protrusions made with the possibility of interaction with the locking keys, and combat stops in the form of locking keys made with the possibility of interaction with the receiver, bolt and bolt frame and with the possibility of limited rotation, according to the invention, in the lower or upper part of the locking keys installed on the receiver or the bolt, protrusions or grooves are formed, made with the possibility of interaction with curvilinear grooves or by the protrusions of the body of the automatic weapon, the lever of the self-timer is installed on the receiver with the possibility of limited rotation and interaction with the bolt at one end, and with the body of the automatic weapon at the other end, and the body of the automatic weapon has a pre-cocking sear made with the possibility of interacting with the receiver and holding it in the position of divorced vice hiccup keys to disconnect the whisperer from the receiver.

Curvilinear grooves or protrusions are made on a separate part fixed on the body of an automatic weapon.

The locking mechanism of the claimed automatic weapon allows you to increase the operational characteristics to increase the reliability of the locking of the automatic weapon because the locking is tightly controlled by the curvilinear groove of the weapon body during the movement of the receiver.

Reduced dimensions and weight of the locking mechanism in the absence of a locking frame.

The manufacturing of the locking mechanism is simplified due to the absence of the shutter frame.

The formation of protrusions or grooves, made with the possibility of interaction with curvilinear grooves or protrusions of the body of an automatic weapon, contributes to the limited rotation of the locking keys during the longitudinal movement of the receiver relative to the body of the weapon and according to the extended or closed position of the locking keys.

Installation of the lever of the self-timer with the possibility of limited rotation and interaction of one end with the shutter and the other with the body of the automatic weapon prevents the receiver from moving forward until the shutter comes to the extreme forward position with the closing keys extended.

The essence of the invention is explained on the example of one of its possible implementations, presented in the drawings.

In Fig. 1 shows the locking key and the location of the key protrusion in the curvilinear groove of the weapon body, bottom view;

in Fig. 2 - components of an automatic weapon, right view.

The locking mechanism of the automatic weapon includes the locking keys 1 (Fig. 1), which are installed on the receiver 2, are made with the possibility of limited deviation to the angle A around the center of rotation of the axis Z and have on the lower surface protrusions 4, which are made with the possibility of interaction with curvilinear grooves 5 of the body 6 of the weapon (Fig. 1) with limited reciprocating movement of the receiver 2 at the distance DI and D2 relative to the body 6 of the weapon. In the body 6 of the weapon, a return spring 7 is installed, which is made with the possibility of interaction with the receiver 2. On the receiver 2 (Fig. 2), on the axis 8, the sear 9 of the self-timer is installed with the possibility of limited rotation around the axis 8, the front protrusion 10 of which has a slope the surface 11, which is made with the possibility of interaction with the inclined surface 12 of the shutter 13 for the possibility of deflecting the sear 9 of the self-timer down a distance H, and its rear projection 14, the end surface of which is a combat stop and is made with the possibility of interaction with the surface 16 of the combat stop of the body 6 of the automatic of the weapon when the rear projection 14 is pressed down by the spring 17, which is made with the possibility of interaction with its lower end with the sear 9 of the self-timer, and the upper one with the receiver 2 15. On the body b of the automatic weapon (Fig. 1), symmetrically curvilinear grooves 5 are made with the possibility of interaction with protrusions of 4 keys 1 closing during reciprocating movement of the receiver 2. Shutter 13 is made with the possibility of interaction when moving and back with the return spring 18, the sear 9 of the self-timer, and at the distance DI (position B of the receiver 2), which corresponds to the extended position of the locking keys 1, is made with the possibility of interaction with the accelerator 19 of the mechanical or gas type, installed in the body b of the automatic weapon. In the case b (Fig. 2) on the axis 20, a spring-loaded spring 21 sear 22 of the preliminary platoon of the receiver 2 is installed with the possibility of limited rotation and interaction with its combat protrusion 23 with the combat protrusion 24 of the receiver 2 to stop it at a distance D2 (the position of the receiver B ) (Fig. 1) from the limiting projection 25 of the body b of the automatic weapon to preserve the reduced position of the closing keys 1 (Fig. 1, Fig. 2). At the same time, the return spring 7 of the receiver, which is installed in the body 6 of the automatic weapon (Fig. 2), is maximally compressed.

The locking mechanism works as follows.

In the initial position, receiver 2 (Fig. 2) with shutter 13 is located in

From the front position and rests against the limiting projection 25 of the body 6 of the automatic weapon.

The protrusions 4 of the locking keys 1 are located in the curvilinear groove 5 of the body 6 of the automatic weapon and correspond to their folded position, while they cover the combat stops of the shutter 13 and close the barrel of the weapon.

To prepare for loading the weapon, it is necessary to move the receiver 2 with the shutter 13 back by the amount of stroke DI (position B). At the same time, the protrusions 4 of the keys 1 of the lock will pass along the curvilinear groove 5 of the body 6 of the automatic weapon at a distance of DI and will take position B, corresponding to their extended position, which will ensure the release of the combat stops 13 of the shutter.

When the receiver 2 is further withdrawn to a distance D2 (position B), the protrusions 4 of the locking keys 1 will move parallel to the receiver 2 without changing the angle, and the shutter 13 will begin to interact with the accelerator 19, which will move it away from the breech of the receiver 2 to a distance that provides release of the front protrusion 10 of the sear 9 of the self-timer. Under the action of the spring 17, the sear 9 of the self-timer will turn around the axis 8, while its front protrusion 10 will rise up to a distance H, and the rear protrusion 14 will go down and become its surface 15 in front of the surface 16 of the combat stop of the body b of the automatic weapon. When the receiver 2 is further moved to the distance D2 (position B), its combat protrusion 24 will go behind the combat protrusion 23 of the sear 22 of the previous platoon of the receiver 2, which will rise under the action of the spring 21 and limit the forward movement of the receiver 2 due to the compressed in the process of retracting the return springs 7. The receiver 2 will take the rear position "B" on the combat projection 23 of the sear 22 of the previous platoon of the receiver 2, and the end surface 15 of the rear projection 14 of the sear 9 of the automatic trigger will be at a distance of DZ from the surface 16 of the combat stop of the housing 6 of the automatic weapon.

To load the weapon, it is necessary to move the released bolt 13 back to a distance D, while compressing the return spring 17 of the bolt 13. When the bolt 13 reaches the rearmost position, it must be released. Under the action of the return spring 18, the shutter 13 will move forward and, acting with its inclined surface 12 on the inclined surface 11 of the front protrusion 10 of the sear 9 of the self-timer, will lower its front part, while the rear protrusion 14 of the sear 9 of the self-timer will rise up and become above the surface 16 of the combat stop of the case 6 automatic weapons 6. When the bolt 13 moves forward, the weapon is loaded.

To fire, it is necessary to lower the combat protrusion 23 of the sear 22 of the previous platoon of the receiver 2 until the receiver 2 is disconnected from the sear 22. The released receiver 2 will move forward under the action of the return spring 7. At the same time, the protrusions 4 of the closing keys 1 will pass along the curvilinear groove 5 a distance D2 and will be in a position corresponding to their closed position, closing the shutter 13. In this position of the receiver 2, the shock-trigger mechanism of the automatic weapon will work and a shot will be fired.

For automatic firing, it is necessary to keep the sear 22 of the preliminary platoon of the receiver 2 in the lower position. Under the action of the pressure of the powder gases, the receiver 2 will move back, passing the DI distances! (position B) to distance D2 (position B). At the DI distance, the accelerator 19 of the shutter will throw the shutter 13 back, while releasing the front projection 10 of the sear 9 of the self-timer. The rear protrusion 14 will lower under the action of the spring 17, and its end surface 15 will take the position DZ in front of the surface 16 of the combat stop of the body 6 of the automatic weapon. After the end of the force of inertia, the receiver 2 under the action of the spring 7 will move forward the distance DZ to the end surface 15 of the rear protrusion 14 of the sear 9 of the trigger into the surface 16 of the combat stop of the body 6 of the automatic weapon and will stop. At the same time, the lock keys 1 will remain diluted. Shutter 13 by inertia will reach the rearmost point and under the action of return spring 18 will move forward. When approaching the inclined surface 11 of the front protrusion 10 of the sear 9 of the self-timer, the shutter 13 with its inclined surface 12 will press on the inclined surface 11, which will lead to the rotation of the sear 9 of the self-timer on the axis 8, raising its rear protrusion 14 until the end surface 15 is disconnected from the surface 16 combat stop of the body 6 of automatic weapons. The released receiver 2 under the action of the spring 7 will go forward until it stops in the limiting protrusion 25 of the housing 6 of the automatic weapon, while the locking keys 1 will be brought by the surface of the curved groove 5 to the position of the closed shutter 13, the trigger mechanism will work and a shot will be fired. Depending on how the shock-trigger mechanism is configured, a shot can be fired during the forward movement of the receiver 2 on the recoil of the moving system (receiver with a barrel - bolt) with the closing keys pressed until the system reaches the extreme forward position. This will lead to a reduction in the recoil speed of the system (decreasing the recoil of the weapon) when firing.
