Description

Technical field

The useful model relates to automatic weapons, and in particular to machine guns such as machine guns, working with a cartridge belt.

BACKGROUND OF THE INVENTION

Various automatic weapons such as machine guns, known to be known in the art, are known in the art, including a cartridge barrel, a barrel to which a barrel is attached, a barrel closure lid, a driver base for directing cartridge movement between the barrel box and the lid for closing the barrel box, a mechanism for fixing the cartridge belt, located outside the place of extraction of the cartridge, a tape feeder mechanism for moving the barrel, and a closed frame with a shutter for touching the cartridge in the chamber of the barrel.

Known machine guns can work with cartridges of different configuration. One known type of cartridge is cartridge cartridge end flange cartridges, for example 7.62x54R or so. "Russian" type of cartridges, which have recently become less used, and the other known type of cartridges have a cartridge case with a peripheral channel, for example 7.62x51 NATO, so-called. "NATO" cartridges that are more widely used in modern times. Both types of cartridges are used in automatic machine guns such as machine guns, which operate on different principles of extraction from the cartridge belt and pushing the cartridge into the barrel, namely through separate mechanisms or by directly pushing the cartridge through the barrel section of the barrel of the weapon.

In conventional conventional machine guns operating peripheral cartridges, such as FN HERSTAL machine guns, the cartridge belt generally extends over the closed frame. These known weapons do not have a separate mechanism for extracting cartridges from the tape and touching them to the cartridge, and this action is carried out directly from the prison by a touching projection. With these weapons, the angle at which the cartridge is fed to the barrel chuck is large, creating an opportunity for jamming, which reduces the reliability of operation.

It is known from U.S. Pat. No. 4,066,000 and other peripheral canal firing ammunition, which can work with both a cartridge and an ammunition cartridge that passes under the shutter. This well-known weapon has a driver base with a cartridge seat on its front to the barrel, sized to the largest cartridge size, and a ratchet feeder to move the cartridge belt toward the driver base. The weapon also does not have a separate mechanism for extracting cartridges from the tape and touching the cartridge, and this action is also carried out directly from the prison. It has the same disadvantage that the angle at which the cartridge is fed to the barrel chuck is large, which reduces the reliability of operation. This well-known weapon has elements located near the point where the cartridge is removed from the belt, which restricts the movement of the cartridge forward along the axis of the weapon and prevents it from falling into the driver's seat prematurely. However, these elements do not fix the cartridge in a specific position to the feeder.

Closest to the essence of the claimed utility model are machine guns that work with flange cartridges, such as Kalashnikov machine guns and Arsenal machine guns. These machine guns include a cartridge barrel, a barrel to which the barrel is attached, a barrel closure lid, a driver base to guide the movement of the cartridge located between the barrel, and a barrel closure lid, with the driver base therein in the back side, a cartridge-extraction bed with a size corresponding to the largest cartridge size, a cartridge-locking mechanism located outside the cartridge-extraction point, a belt-feeder for moving the cartridge th and closed frame with imprisonment for dotikvane the cartridge in the chamber of the barrel. These weapons have in addition to the above mechanisms and two separate mechanisms, namely: a first mechanism for removing the cartridge from the belt unit - a cartridge carrier, which mechanism is mounted on the shutter, and

1543 Ul second lowering mechanism lower than the cartridge, which second mechanism is mounted on the lid of the barrel. The first mechanism pulls out the cartridge and pulls it back from the belt, and the second mechanism presses the cartridge pulled out and removes it to a bed formed at the base of the driver, from which it will be pushed into the barrel chuck from the shutter. This type of machine gun has the advantage that the insertion of the cartridge into the barrel of the barrel is at a very small angle and is smoother because it is carried out in two stages, which reduces the possibility of detecting the weapon and improves its reliability. In addition, fixing the cartridge flange cartridges as they move to the point where the cartridge is removed from the belt is more stable because the driver base has a groove that slides the cartridge sleeve flange, which restricts cartridge movement back and forth. along the axis of the weapon. Known automatic weapons cannot handle cartridges with a peripheral channel, since the cartridge extraction mechanism from the cartridge belt is not adapted to retrieve the cartridge, using the peripheral sleeve channel and the weapon can only operate reliably if the cartridge is securely secured to the base the driver.

The technical nature of the utility model

The task of this utility model is to create an automatic weapon that can handle cartridges with a peripheral channel, feed the cartridge into the barrel smoothly and at a smaller angle.

The task is accomplished with an automatic weapon including a barrel with a chuck, a barrel to which the barrel is connected, a barrel closure lid, a driver base for directing the movement of the cartridge located between the barrel and the barrel closure lid, with the driver's base having in its back side a bed for extracting from the tape a cartridge of the size corresponding to the largest size of the cartridge, a mechanism for fixing the cartridge located outside the place of extraction of the cartridge, tape feeders belt conveyor, a shutter frame with a barrel for pushing the cartridge into the barrel chuck, a first cartridge retrieval mechanism from the barrel unit mounted on the barrel, and a second lower cartridge retaining mechanism, which is mounted on the lid of the barrel box. According to a useful model, the weapon also includes at least one mechanism for fixing the cartridge to the base of the driver before removing the cartridge from the belt, which mechanism is located at the place of extraction of the cartridge from the tape.

The advantage of the utility model is that the automatic weapon has the ability to work with cartridge with a peripheral channel, the extraction of the cartridge from the belt unit is at a very small angle and is smoother, ensuring a secure fixation of the cartridge to the base of the driver before extraction from the ribbon.

In a preferred embodiment, the automatic weapon includes two cartridge locking mechanisms, the second cartridge locking mechanism being located at the location of the cartridge adjacent to the recoil. This ensures the uniform placement of these cartridges, which improves the reliability of retrieval.

In another embodiment, the cartridge locking mechanism is spring-loaded, which ensures the secure locking of wide-bore cartridges.

In another embodiment, the cartridge locking mechanism is mounted on the lid of the barrel box, which provides easy access to the mechanism.

Explanation of the annexed figures

The utility model is illustrated by an exemplary embodiment, in which Figure 1 is a sectional view of a barrel box, a barrel cover and a base of an automatic weapon driver with two cartridge locking mechanisms.

Exemplary implementation of the utility model

The accompanying figure shows a partial section of the automatic weapon according to one exemplary embodiment of the utility model. The weapon shown includes a barrel box 1 in which a barrel 2 and a shutter frame 3 are mounted. The barrel box 1 is closed with a lid 4, with the driver's base 5 serving between the barrel 1 and the lid 4 for guiding purposes.

1543 Ul movement of cartridge 6. The weapon has a mechanism for fixing cartridge 6, shown in this case as a spring. This mechanism in this embodiment includes a locking pin 7 and a spring 8 mounted on the lid 4 of the barrel box. In the case 4 of the barrel are mounted in this case two mechanisms for fixing the cartridge, each of which contains interconnected movable support 9, 9 'and a spring 10, 10', attached to the lid 4. In the case of the exemplary embodiment shown, the two movable supports 9 and 9 'are connected to each other by an axis 11, also mounted on the cover 4 (not shown in the figure), around which the axis 11 can rotate the movable supports 9 and 9' under the influence of the springs 10 and 10 '. In FIG. 1 also shows a ribbon feeder for moving the cartridge belt 6. The ribbon feeder includes a feed lever 12 and a feed finger 13 connected to each other by a spring 14 that is twisted. The cartridge ejection mechanism and the lower cartridge ejection mechanism are not shown in the drawing.

Using the utility model

Automatic weapons according to the example implementation works as follows.

As the shutter frame 3 moves back, the feed lever 12 rotates and with the feed finger 13 touches the cartridge belt 6 with the cartridges one step forward in the direction of movement of the ribbon perpendicular to the axis of the weapon. In this movement, the first cartridge presses and lifts up the locking pin 7 and passes under it. Under the action of the spring 8, the locking pin 7 returns to its initial position, thereby preventing the cartridge belt from reversing. At the end of the stripe step, the first cartridge stands under the movable support 9 and the next cartridge under the second support 9 ', which, under the action of the springs 10 and 10', press the front end of the cartridges to the base of the driver 5 so that they occupy a certain position for grasping the first cartridge from the mechanism for removing the cartridge from the belt. The supports 9 and 9 'are fixed with the axis 11 to the cover 4 of the barrel box 1 and are arranged in their respective sockets. As the shutter frame 3 moves forward, it interacts with the feed lever 12 and rotates. The feed pin 13 moves downwards, slides under the next cartridge and shrinks the spring 14. After passing the next cartridge, the spring 14 lifts the feed ring 13 to its starting position and is ready to touch the next cartridge. At this point, the first and second cartridges are pressed by the movable supports 9 and 9 'to the base of the driver 5, and the locking pin 7 prevents the cartridge belt from reversing. This ensures a uniform and reliable positioning of the cartridge for its capture by the cartridge ejection mechanism. At the end of the movement of the shutter frame forward along the axis of the weapon, the mechanism for removing the cartridge from the belt engages the first cartridge. When the shutter frame is reversed, the cartridge ejection mechanism pulls the first cartridge out of the strap 6, the cartridge removal mechanism downward presses the cartridge against the bed formed at the base of the driver 5, from where, when the shutter frame 3 moves forward, the shutter takes the cartridge and touches it. into the barrel of the barrel and a shot is fired.
