Description

The invention relates to weapons technology, namely to pistols with a longitudinally sliding bolt (mainly to self-loading combat and sports pistols and to firearms of limited destruction).

A well-known PM pistol with a longitudinally sliding bolt and barrel fixed on the frame is indivisibly and motionless (see Mikhailov L.E. “Designs of small automatic weapons”, 1983, Moscow, p.25 “order of disassembly and assembly”). The known gun has a movable bracket, the movement of which makes it possible to divert the shutter to its extreme rear position and remove it from the frame guides.

To produce assembly and disassembly of a known pistol, it is necessary to take the bolt to its extreme rear position. This overcomes the great effort of the return spring, which is in the loaded state, which is not safe and can lead to personal injury.

The well-known Yarygin pistol “ПЯ” (“Kalashnikov. Weapons, ammunition, equipment”, No. 6, 2003, Publishing House LLC “Azimut”, pp. 7-14), works on the basis of automation that uses recoil energy with a short barrel rollback. The barrel of the gun "ПЯ" has a ledge, which is placed in the groove of the frame. In this case, a groove is made on the protrusion of the barrel, and a hole is made in the frame for placement of a detachable contactor in them (in the groove of the protrusion and in the hole of the frame). When disassembling this gun, it is necessary to remove the detachable contact from the frame, move the shutter with the barrel forward, and then separate the barrel from the shutter.

The known device, taken as a prototype, cannot be used as a firearm of limited destruction (as a weapon of self-defense), since such a weapon of limited destruction can be converted into a combat one, replacing the detachable barrel for this.

The objective of the claimed invention is to expand the scope and improve the operational characteristics of weapons.

The problem is solved in that in the gun containing the frame, the barrel with a protrusion placed in the groove of the frame, and a detachable contactor installed in the hole of the frame, the barrel is permanently installed in the frame by means of a pin, one-piece mounted on the frame and placed in the groove made on the protrusion trunk, and detachable contactor installed in the hole made on the protrusion of the barrel. The groove for the pin and the hole for the detachable contactor on the protrusion of the barrel are paired.

The claimed device allows you to expand the scope and can be used not only as a military, but also as a firearm of limited destruction. Its design excludes the possibility of altering firearms of limited destruction into combat, since it is impossible to replace the barrel without destruction. In addition, the design of the claimed gun simplifies the production of assembly and disassembly and increases their safety.

The claimed device is illustrated in the drawing, which shows:

- figure 1 is a General view of the device;

- figure 2 - section aa in figure 1 (the shutter is not conventionally shown);

- figure 3 is a section bB in figure 1 (the shutter is not conventionally shown);

- figure 4 - view In figure 1 (the hole for the detachable contactor and the groove for the pin are made paired);

- figure 5 is a view In figure 1 (the hole and the detachable contactor located therein are made in a square shape);

- 6 - the position of parts and components of the device at the time of disassembly.

The gun contains a frame 1 (figure 1); barrel 2 with a protrusion 3 (figure 2), placed in the groove 4 of the frame 1; detachable contactor 5 (figure 3) installed in the hole 6, made in the frame 1 and on the protrusion 3 of the barrel 2, and the shutter 7 (figure 1). The pin 8 (figure 2) is permanently installed in the frame 1 and at the same time is placed in the groove 9 made on the protrusion 3 of the barrel 2 (the protrusion 3 can be performed on the barrel coupling, not shown in the drawing). The hole 6 (figure 4) for the detachable contactor and the groove 9 for the pin can be made paired. In addition, the contactor 5 (figure 5) may have a rectangular or square shape, and the hole 6 in this case corresponds to it in shape.

The ready-to-shoot pistol barrel (Fig.1) is in a stationary position. The longitudinal movement of the barrel ready for shooting is limited by a detachable closure 5 (Fig. 3) installed in the hole 6 on the frame 1 and on the protrusion 3 of the barrel 2. The lateral movement of the barrel is limited by the shutter 7 (Fig. 1) and the groove 4 (Fig. 2) of the frame 1, which includes the protrusion 3 of the barrel 2. Rotational movement is limited by the interaction of the muzzle of the barrel 2 (Fig. 1) with the shutter 7. The integral part of the barrel 2 with the frame 1 is provided by a pin 8 (Fig. 2), which is permanently installed in the frame 1 and placed in the groove 9 on the ledge 3 of the barrel 2.

When disassembling, it is necessary to remove the detachable contactor 5 (Fig. 1), while the barrel 2 becomes movable relative to the frame 1 within the groove 9 in which the pin 8 is located. Next, the barrel 2 (6) must be pushed with the shutter 7 forward to the limit pin 8 into the back wall of the slot 9. After that, it is necessary to pull the bolt 7 back and move it up and forward to remove it from the gun. In this case, the barrel 2 retains its inseparable state with the frame 1.
