Abstract

The utility model relates to a gas-cylinder weapon operating using compressed gas. The gas-cylinder weapon contains a barrel and a detachable magazine, which includes a housing and a spring located in the casing. The spring is made with the possibility of preloading the body to the breech cut of the barrel. In the lower part of the casing, on the front wall, there is a window in which the casing protrusion is located. When assembling the detachable magazine, the body is fixed in a position that helps to eliminate the gap between the breech cut and the body of the detachable magazine, due to the joint work of the spring and the protrusion of the body interacting with the casing window. In the absence of a gap between the breech section and the body of the detachable magazine, the bullet is not displaced relative to the barrel bore and can freely pass through it, which increases the bullet speed and firing accuracy. 1 wp f-s, 3 ill.

Description

Known gas-cylinder weapon model "JUNKER", taken as a prototype (see the operating manual "Rifles pneumatic gas cylinder" JUNKER "" https://docplayer.ru/36138962-Vintovki-pnevmaticheskie-gazoballonnye-yunker-rukovodstvo-po-ekspluata html), including a breech-cut barrel, a detachable magazine containing a body housed in a casing and a valve system with an outlet.

The disadvantage of the known gas-cylinder weapon is the low speed of the bullet and insufficient firing accuracy due to the displacement of the bullet in the valve outlet relative to the barrel. Bullet displacement occurs due to the large and unstable size of the gap between the breech cut and the body of the detachable magazine. Gas leaks through the gap when fired. In addition, due to the displacement of the bullet, the energy of the compressed gas is spent not on communicating kinetic energy to the bullet, but on its alignment in the bore. This leads not only to a decrease in the bullet speed, but also to a decrease in the stability of the bullet speed, therefore, the firing accuracy is not high enough.

The task of the utility model is to increase the bullet speed and firing accuracy.

The technical result consists in eliminating the displacement of the bullet in the valve outlet relative to the barrel.

The problem is solved due to the fact that the gas-cylinder weapon contains a barrel with a breech cut and a detachable magazine, including a body located in the casing, and a valve system with a valve outlet, in which, according to the utility model, the detachable magazine is equipped with a spring made with the possibility of pressing the body to breech cut, while in the lower part of the casing on the front wall there is a window in which the protrusion of the casing is located. One end of the spring is bent upward and acts on the lower part of the body opposite to the projection, and the other end of the spring is fixed in the casing.

The proposed design of a gas-cylinder weapon makes it possible to eliminate the gap between the breech-cut and the detachable magazine body due to the inclusion of a spring in the detachable magazine design, which presses the body to the breech-cut, and also due to the fact that even before the detachable magazine is installed in the gas cylinder weapon, the body is fixed in a position that contributes to the exclusion clearance due to the joint work of the spring and the protrusion of the housing interacting with the casing window.

The declared utility model is illustrated by the following drawings:

fig. 1 General view of a gas-cylinder weapon in section;

fig. 2 remote element A;

fig. 3 detachable magazine of gas-cylinder weapons assembly.

Gas-cylinder weapons include a barrel 1 with a channel 2 and a breech cut 3, a bushing 4 and a detachable magazine (Fig. 1). Bushing 4 is located on the breech of the barrel. The detachable magazine contains a housing 5, located in the casing 6, and a spring 7. A protrusion 8 is made in the lower part of the casing 5, and in the casing 6 there is a window 9 to accommodate the protrusion 8 of the casing 5.

The bushing 4 is made with a stop 10 (Fig. 2) in the form of a protrusion. In the upper part of the housing 5, there is an outlet opening 11 of the valve and a groove 12. In the groove 12 of the housing 5, a supporting surface 13 is made, which corresponds to the stop 10.

The detachable magazine is equipped with a spring 7. The spring 7 is configured to press the housing against the breech cut 3. In a preferred embodiment, one end of the spring 7 from the side of the housing 5 is bent upwards, and the other end of the spring 7 is fixed in the housing 6. Thus, the spring 7 can act on the housing 5 not only in the direction B (vertically upward relative to the lower part of the housing 5), but also in the direction C (from the lower part of the housing 5 opposite to the projection 8 to the breech cut 3).

The claimed utility model will be further considered on the example of a version of the spring, one end of which is bent upwards, and the other end is fixed in the casing.

Gas-cylinder weapons work as follows.

In order to assemble the detachable magazine, it is necessary to install the housing 5 into the housing 6 until it contacts the spring 7 and press the housing 5. Then the bending of the spring 7 will act on the housing 5 and direct the protrusion 8 into the window 9. Under the action of the spring 7 in the direction C and resting on the wall of the window 9 with the protrusion 8, the body 5 will be pressed against the front wall of the casing 6 (Fig. 3). Placing a detachable magazine in a gas-cylinder weapon with this position of the body 5 in the casing 6 helps to reduce the size of the gap between the breech cut 3 and the body 5. Further, when installing the detachable magazine in the gas-cylinder weapon, the spring 7, acting on the body 5 in the direction C, tightly presses the body 5 to breech cut 3 and the gap is eliminated.

Due to the action of the spring 7 in the direction B, when the detachable magazine 5 is installed in the gas-cylinder weapon, the support surface 13 is pressed against the stop 10. Thus, the coaxiality of the bore 2 of the barrel 1 and the valve outlet 11 is achieved. In this case, the housing 5 in the casing 6 is displaced downward and the protrusion 8 comes out of contact with the wall of the window 9 of the casing 6, but remains inside the window 9.

In order to disassemble the detachable magazine, it is necessary to remove it from the gas-cylinder weapon, press the protrusion 8 of the housing 5 and remove it from the window 9 of the casing 6. Then the spring 7 will push the housing 5 out of the casing 6. The detachable magazine is disassembled and you can equip it with a can of gas and bullets.

In the absence of a gap between the breech cut and the body of the detachable magazine, as well as observance of the alignment of the barrel bore and the valve outlet, the bullet is not displaced relative to the barrel bore and can freely pass through it. This improves bullet speed and shooting accuracy.
