Description

The invention relates to the field of military equipment and can be used in training shooting devices, which use standard cartridges with a tracer bullet and an impact capsule, for disposable and reusable grenade launchers and flamethrowers.

To train personnel in shooting from grenade launchers or flamethrowers, training shooting devices are used that have a rifled barrel that provides the bullet with a flight path close to the flight path of a grenade at certain firing ranges.

A device for firing practice (CCP) for the LAW grenade launcher, consisting of a special launcher, a training grenade and a carrying strap [1].

Shooting is carried out from the shoulder by a sub-caliber grenade simulating firing from a combat grenade launcher with a combat grenade. The training grenade has a flight path close to a combat grenade, and therefore the missile launcher has the same sighting system as a combat grenade launcher.

The disadvantage of this missile launcher is its high cost, since it is not the grenade launcher itself that is used for training, but a specially manufactured simulator and specially manufactured ammunition.

Also known training shooting device (PUS-7) for RPG-7 grenade launcher [2]. It consists of a body with a barrel, a movable shutter, a spring-loaded sear. To load the PUS-7, it is necessary to remove it completely from the grenade launcher, open the bolt, insert the cartridge into the chamber, close the bolt, cocking the hammer, and fold the bolt handle forward. When loading the launcher with a cartridge and when loading the launcher with a launcher, it is necessary to hold the launcher with the head part towards the target, as The presence of a constantly cocked drummer can lead to an accidental shot. All this makes the PUS-7 unsafe in case of violation of operating methods.

A device for training shooting according to the patent of the Russian Federation No. 2199071, C1, class. F 41 A 33/00, 02.20.2003.

It is intended for training personnel in the methods and rules of conducting targeted fire in training personnel in training centers. The device for training shooting includes a bolt, a trigger mechanism, a housing into which a barrel with a chamber is inserted. A cylindrical chamber with a screw screwed onto it is fixed to the housing using studs and nuts. There are eight throttling holes in the cover. The device allows you to combine the flight path of a bullet with the flight path of a grenade at all sighting ranges.

The invention solves the problem of increasing the operational safety of the firearm, and also provides the correct procedure for bringing the firearm to the combat and traveling position, which is extremely necessary when training personnel in firing techniques.

To solve the problem in training shooting device containing a housing, a bolt, a barrel, a trigger mechanism, new, according to the invention, is that it is equipped with a pusher, the housing is placed in a container with a folding handle, and the bolt has a rammer with a segment console . A tip with a stop mounted on it is placed on the spring-loaded thrust of the trigger mechanism, interacting through a groove formed in the container with the segment console of the rammer.

The housing is equipped with a shutter stop that excludes the shutter’s impact on the sear, and a spring-loaded latch mounted to interact with a hole formed on the outer surface of the shutter.

The invention is illustrated by drawings, where:

figure 1 shows the breech of the CCP;

figure 2 shows the interaction of the segment console rammer with emphasis in the intermediate position when locking;

figure 3 shows a section along the skirt of the shutter with a fully closed bore;

figure 4 shows the position of the segment console when

completely closed bore;

figure 5 shows a cross section for stopping the shutter with a fully closed bore;

figure 6 shows the position of the segment console with a fully open bore.

The training shooting device includes a container 1 with a trigger 2 and a folding handle 3, a firing device 4 with a trigger mechanism 5 and a pusher 6 fixed in the container.

A segment console 9 is formed on the rammer 7 of the shutter 8, and a tip 11 with a stop 12 mounted on it is placed on the draft of the container trigger mechanism, interacting through a groove 13 formed in the container with the segment rammer console. The housing 14 is equipped with a stop 15 of the shutter, eliminating the effect of the shutter 8 on the sear 16. The spring-loaded lock of the shutter 17 is placed in the housing, and a hole 18 is made on the outer surface of the shutter 8.

To load the control panel, we remove the bolt 8 with a spring-loaded striker 19 from the firing device 4, mounted in the container 1. We place the cartridge in the groove of the bolt, insert the bolt into the housing 14, pressing on the rammer 7, direct the bolt 8 forward to the stop in the breech section of the barrel 20, compressing while the mainspring of the trigger mechanism of the firing device and, acting through the segment console 9 of the rammer on the rear end 21 of the support 12, we shift the rod 10, partially compressing the spring 22 of the trigger mechanism of the container. In this case, a gap 23 is formed between the working surfaces of the trigger 24 and rod 10, which completely turns off the trigger mechanism of the container during loading of the CCP, and therefore the ability to release the trigger mechanism of the container in any intermediate position of the shutter, because the rod 10 does not come into contact with the trigger 24. Then we turn the shutter clockwise until the stopper of the rammer console in stop 15 of the shutter installed on the rear end of the housing 14, the locking protrusion 25 on the shutter skirt comes off the whisper 16, the spring-loaded lock 17 engages hole 18 on the surface of the shutter, fixing it from turning back, counterclockwise. With this position of the shutter 8, a guaranteed gap 26 is formed between the side wall of the window on the skirt 27 of the shutter 8 and the side wall of the whisper 16.

The interaction of the segment console 9 of the rammer with the stop 12 ends, the spring-loaded rod 10, moving backward, selects the gap 23 formed when locking and sits on the trigger 24. Then we unlock the handle 3 on the container 1, rotate it to a fixed vertical position cock the spring of the trigger.

ICE is ready to fire.

To produce a shot, press the trigger 24 of the container. The spring-loaded rod, moving backward, extrudes the pusher 6 with the cone 28 of the tip 11, which at its opposite end acts on the working shoulder of the whisper 16, disengaging it from the striker 19. The spring-loaded striker moves forward and pricks the cartridge capsule. A shot is taking place.

It is not possible to discharge an ICE in violation of the procedure for bringing it into the stowed position, the rod with the tip and the stop placed on it is in the extreme rear position, which prevents the shutter from turning counterclockwise.

To unload the control system, unlocking the handle, turn it to a fixed horizontal position, the trigger spring, compressing, returns the rod with the tip and the stop placed on it to its original position, after which it becomes possible to turn the shutter counterclockwise. By turning the shutter, the segment console 9 interacts with the stop 12 on the tip 11 of the rod 10, squeezes it, again forming a gap 23 between the working planes of the trigger 14 and the rod 10. At the beginning of the rotation of the shutter, a spring-loaded lock 17 is pressed from the hole 18 on the shutter, blocking the protrusion 25 on the skirt 27 of the bolt covers the working shoulder whispered 16. After the release of the fighting stops of the bolt out of engagement with the barrel, we remove the bolt with a fired sleeve from the housing 14 of the shooting device 4.

Remove the sleeve from the groove of the shutter.

The ICP is ready for subsequent loading.

Thus, the ICE is reliable, safe in case of violation of the operating rules, and its design provides the correct procedure for bringing it into combat and marching position, which is extremely necessary when training personnel in firing techniques from RPO-A combat infantry flamethrower.
