Description

The invention relates to weapons technology and can be used in carbines, rifles and rifles with a longitudinally-sliding bolt.

In order to save expensive ammunition, hunt small game, use city shooting ranges to improve shooting skills, add-on trunks are used under a budget cartridge (see, for example, UK patent No. 2136935, IPC F41C 21/22; 21/10, publ. 09/26/1984 or UK patent No. 1383787, IPC F41C 21/10, publ. 02/12/1975). Replacing trunks is a time-consuming process and does not provide a stable result.

Known insert shafts for cartridges of various calibers for smooth-bore guns, providing a reduction of the trunks (see, for example, insert barrel on autosw. No. 1623356, IPC F41A 21/10, prior. 08/29/1988).

An inserted barrel is installed inside the barrel of the main weapon and is centered in it by the front and rear supporting surfaces of the body.

This design provides better accuracy in comparison with the above counterparts.

It is known the use of plug-in cartridges for firing budget .22 caliber cartridges (for example .22 LR) from a weapon (carbine, rifle or shotgun) under a powerful .22 caliber cartridge.

Such a weapon includes a bullet-shot gun adopted as a prototype, in which (for a rifled barrel) a loose cartridge chamber is used according to autosw. USSR No. 910024, IPC F41C 21/12, prior. 02/22/1980.

Insert chamber consists of an adapter, spring-loaded clips, shutter and striker. The assembled insert chamber is inserted into the barrel of the gun and fixed in it. The insert chamber expands the possibilities of using rifles with a rifled barrel (carbines, rifles) due to the possibility of switching from one type of ammunition to another.

However, firing using a loose chamber is possible with cartridges whose caliber corresponds to the caliber of the barrel, and after a shot it is necessary to reload manually, which is very problematic when using carbines or rifles.

The invention solves the problem of improving the operational characteristics of weapons with a longitudinally-sliding bolt under the cartridge of any caliber.

This problem is solved due to the fact that in weapons with a longitudinally-sliding bolt containing a barrel, a box, a bolt with a striker and a trigger, the following is new:

- a firing device is installed on the box, including a barrel, a magazine and a sliding bolt;

- the shutter of the firing device interacts with the shutter of the weapon, for which the latter has a figured hole, and the shutter of the firing device is equipped with a protrusion;

- a spring-loaded striker is installed in the shutter of the firing device, interacting with the firing pin of the weapon and the insert of the firing device;

- the weapon box has a window in which grooves are made;

- accordingly, racks are installed in the firing device, of which the front has the possibility of longitudinal movement under the action of a rotating sleeve, and the rear - of the transverse movement with fixing by a nut.

The invention is illustrated by drawings, which depict:

- figure 1 - firing device for weapons before firing;

- figure 2 - firing device on weapons at the time of the shot;

- figure 3 is a device on a weapon at the time of reflection of the sleeve;

- figure 4 - weapons without firing device, with a plug installed in the skeleton of the bolt;

- figure 5 is a section aa in figure 4;

- figure 6 is a General view of a weapon (carbine) with attached firing device.

The weapon (in this case, the carbine) consists of a box 1, in which the barrel 2 is installed. Two slots 4 and 5 are formed in the window 3 of the box 2. it is closed by a plug 9, and in the drummer 10 a curly groove 11 is formed.

The firing device consists of a box 12, in which a longitudinally moving bolt 13 is installed. The device also has a front strut 14 with a sleeve 15, as well as an insert 16 with a rear strut 17 fixed by a nut 18.

The bolt 13 of the firing device has a protrusion 19, interacting with the figured hole 8 of the frame 7 of the bolt 6 of the carbine. In the bolt 13, a spring-mounted striker 20 is installed, which, interacting with the striker 10 and the liner 16, moves in the bolt 13. In addition, the firing device has a barrel 21 and a magazine 22 installed in the box 12.

A carbine with a firing device interact as follows. To load the firing device, it is necessary to insert the magazine 22 with cartridges into the corresponding window of the box 12 of the firing device, then open the bolt 6 of the carabiner and move it to its extreme rear position. In this case, the shutter 13 of the firing device, driven by the protrusion 19, interacting with the figured hole 8, will move back to the limit in the liner 16 of the firing device. Next, the bolt 6 of the carabiner is moved forward and close it. At the same time, the bolt 13 of the firing device, driven by the bolt 6 of the carbine, will send a cartridge from the magazine 22 to the barrel chamber 21 and ban it. To produce a shot, it is enough to lower the drummer 10, which, through the striker 20, will break the capsule. A shot will happen.

To produce the next shot, it is enough to open the shutter 6 and take it to its extreme rear position. In this case, the ejector removes the sleeve from the chamber of the barrel 21, and the firing pin 20, interacting with the liner 16, moves and reflects the sleeve.

When moving the shutter of the firing device 13 forward, the cartridge from the magazine 22 is sent to the chamber, and the firing pin 20 will take its original position under the action of the spring. When locking the bolt 6 of the carabiner, the bolt 13 of the firing device is locked. The device is ready for the next shot.

To bring the firing device to normal combat, it is necessary to loosen the nut 18, adjust the position of the pillar support of the rear 17 and fix its position with the nut 18.

To disconnect the firing device from the weapon, it is necessary to rotate the front rack 14 out of engagement with the groove 4 of box 1, turning the firing device around the center located in the area of the rear rack 17 with the groove 5 of box 1, to separate it from the weapon. Next, separate the bolt 6 from the weapon and install the plug 9 in the figured hole 8 until it is latched.
