Description

The utility model relates to small arms, namely to devices that allow the use of blanked and signal small arms, and can be used in pistols, revolvers, rifles, etc.

Known pneumatic training nozzle containing a housing, a barrel for projectile equipment, a piston with a guide rod, a compression chamber and a return spring, output channels. The nozzle can be equipped with an element for placing projectile equipment with a rotary feed mechanism, an element for twisting the projectile equipment and an element for narrowing the bore of the weapon (RF patent No. 2680952, publ. 28.02.2019).

The closest in technical essence of the proposed utility model is a training attachment containing a body with an attachment to the weapon, a barrel, a gas channel designed to pass a smaller part of the gas, and at least one outlet channel to exit the majority of the gas (RF patent No. 2674917 , published on December 13, 2018).

The disadvantage of the known devices is the complexity of their design and the lack of versatility due to the need for the attachment to make changes to the external design of the weapon, namely, special cartridges are needed for each weapon individually. In addition, for the operation of automation, it is proposed to narrow the barrel, which involves either manufacturing a new barrel for a specific weapon, or the nozzle must have an additional obstacle specifically for the barrel of each type of weapon that enters the barrel bore to ensure operation.

The disadvantage is also low reliability due to the fact that the known nozzles are a continuation of the barrel and are hermetically fixed with it, which, under excessive pressure of powder gases, can lead to the destruction of the structure. Reliability is also reduced by the fact that the spring for the operation of the rammer and the rammer itself are not isolated from the action of powder gases, which leads to a rapid loss of device performance, since under the influence of high temperatures of the powder gases and a high shock load, the spring quickly loses its properties, and the rammer becomes motionless due to powder deposits and deformation.

The utility model is aimed at improving the reliability of the design by eliminating excessive loads on the elements of the nozzle and ensuring its versatility due to the possibility of using blank cartridges of any power in its application; accordingly, it is possible to adapt it to any weapon intended for firing with blanked and signal missiles, while maintaining the reliability of the nozzle.

The problem is solved by the fact that the attachment to the weapon for firing projectile elements contains a body made with the possibility of attachment to the weapon, a barrel mounted in front of the muzzle of the weapon with the possibility of longitudinal movement relative to its axis, a magazine for placing projectile elements with a spring-loaded cutter for supplying projectile elements to the barrel mounted with the possibility of interaction with the bolt frame of the weapon.

In addition, the part of the barrel, located closer to the muzzle of the weapon, may have a conical narrowing towards the muzzle of the weapon.

At the same time, the body of the nozzle can be made with the possibility of placing a body of a pistol-type weapon into it.

Installing the nozzle barrel in front of the muzzle of the weapon with the possibility of longitudinal movement relative to its axis allows you to adjust the volume of powder gases falling directly into the barrel with the projectile to save the energy of the shot, depending on its initial power. At the same time, blank cartridges of any power can be used in the weapon itself without changing its design, which makes the nozzle universal for use on different weapons.

The cutter for supplying projectiles to the barrel, installed with the possibility of interacting with the bolt frame of the weapon, makes it possible to reduce the load on the cutter spring by combining the movement of the cutter and the bolt frame, which increases the reliability of the device.

The implementation of the part of the barrel, located closer to the muzzle, with a conical narrowing makes it possible to ensure that only a certain amount of gases enter the barrel due to cutting off the excess volume of gases, which, due to the taper, is discharged along the barrel without getting into it, which increases the reliability of the design and its versatility when using blank cartridges of any power.

The execution of the nozzle body with the possibility of placing a pistol body in it allows you to get a weapon like a rifle, which increases the versatility of the nozzle.

The proposed utility model is shown in the drawings.

In FIG. 1 shows the body of the nozzle, in which the body of the gun is placed; in fig. 2 schematically shows the nozzle located in front of the muzzle of the weapon, before the shot; in fig. 3 - the same, after the shot.

Attachment to the weapon for firing projectiles contains a body 1, made with the possibility of fastening to the weapon 2, using, for example, a thread (not shown), a barrel 3 installed in front of the muzzle 4 of the weapon 2, a store 5 for accommodating projectiles 6 with a spring 7 to feed them into the barrel 3. The barrel 3 is attached to the body 1 by means of a threaded connection (not shown) with the possibility of longitudinal movement relative to its axis along the thread (not shown), which allows you to adjust the distance to the muzzle of the weapon 4. The cutter 8 for supplying projectiles is equipped with spring 9 and is installed with the possibility of interaction with the bolt frame 10 of the weapon 2. The part of the barrel 3, located closer to the muzzle 4, may have a conical narrowing 11 towards the muzzle 4. The body 1 of the nozzle can be made with the possibility of placing the body of the weapon 2 into it pistol type (Fig. 1).

The proposed nozzle works as follows.

The body 1 of the nozzle is placed on the barrel of the weapon 2. Depending on the power of the blank cartridge, the distance between the muzzle 4 of the weapon 2 and the barrel 3 is adjusted by rotating it along a threaded connection (not shown). Throwable elements 6 are located in the magazine 5, while the cutter 8 blocks the supply of missile elements 6 into the barrel 3 of the nozzle. At the moment of firing a blank cartridge, part of the powder gases escaping from the muzzle 4 enters the barrel 3 and, continuing to move, pushes the projectile 6 out of the barrel 3. The powder gases that did not enter the barrel 3 continue to move along the conical narrowing 11 and are discharged into a gap between the body 1 of the nozzle and the weapon 2 (not shown). In this case, the bolt frame 10 begins to move backward, and the cutter 8 follows it under the action of the spring 9, allowing the next missile element 6, pushed out of the magazine 5 by the spring 7, to enter the barrel 3. At the same time, the cutter 8 and its spring 9 do not experience excessive loads . Then the cycle repeats.

Thus, the proposed nozzle has a reliable design due to the elimination of excessive loads on its elements and is universal due to the possibility of using blank cartridges of any power in its application; accordingly, it is possible to adapt it to any weapon intended for firing with blanked and signal missiles, while maintaining the reliability of the nozzle.
