POWDER MOUNTING PISTOL CARTRIDGE MECHANISM

The utility model relates to the field of powder-mounted guns and can be used in devices for construction works.

Known cassette feeding mechanism, implemented in a manual device for driving pins by the action of pressure of powder gases according to USSR patent No. 326768 (publ. 19.1.72, bull. No. 4), comprising a housing with a two-arm lever, one shoulder interacting with a rolling recess resting on the bottom the barrel with a lever and equipped with a spring-loaded dog pivotally hinged to the end of the other shoulder, which, with its own tooth, enters the lateral clips of the cage - tape (cassette), moving the latter backwards during the course of the barrel.

The known mechanism allows the promotion of a cartridge, for example, a clip-tape simultaneously with the platoon of the trigger mechanism.

A disadvantage of the known mechanism is the excessive complexity and complexity associated with the need to use systems of several levers, which does not allow placing it in a compact case.

The objective of the utility model is to simplify the mechanism and increase its compactness.

The technical result is to reduce the amount used in. leverage mechanism.

In order to achieve the stated objective, a lever with a spring-loaded dog attached to the end of the lever, which with its own tooth enters the side samples of the cartridge, moving the latter during the barrel backward, is introduced into the known mechanism for feeding the cartridge cartridge of the powder gun, including a movable barrel, a guide groove is introduced in the rod of the movable barrel and shutter, and the lever is made single-arm having a pin made with the possibility of changing K1PK7V25S1 / 4

- the rod is rigidly fixed to the movable barrel;

-the groove is curved relative to the longitudinal axis;

-the groove has locking protrusions;

- The pin is fixed on the lever between the hinge and the point of attachment of the dog.

The utility model is illustrated by means of the drawings, where in FIG. 1 shows the uncharged cassette feeding mechanism of the powder gun; FIG. 2 - cocked mechanism.

The gun feed mechanism for the gun mount gun includes a movable barrel 1 with a rod 2, a single-arm lever 3 with a spring-loaded dog 4 fixed on the end of the lever 3, a guide groove 5 in the rod 2 of the barrel 1, the shutter 6, the lever 3 has a pin 7 and is fixed with using the hinge 8. The dog 4) is screwed with its tooth 9 into the side selections 10 of the cartridge 11 with cartridges 12.

The feed mechanism of the cartridge powder gun mount works as follows.

In the initial state (after firing) the barrel 1 with the guide groove in the rod 2 is advanced forward. Since the pin 7 is in the groove 5 of the thrust 2 of the barrel 1 ,. a

the lever 3 is pivotally mounted on the shutter 6, then the end of the lever 3 is in the lower position. Dog 4 is included in the side samples 10 of the cartridge 11. The cartridge is a clip - a tape with cartridges.

When the barrel 1 rests on an obstacle (the surface being machined), the barrel 1 moves backward, the pin 6 moving in a bent in the groove 5, raises the lever 3, which, acting through the dog 4 on the cartridge 11, pulls the cartridge up until its cartridge is installed in the opposite position to the chamber (on the drawing is not indicated). The magnitude of the bend of the groove determines the stroke of the lever in a vertical plane.

The presence of protrusions in the groove 5 secures the pin 7 in the extreme positions of the groove.

The location of the trunnion between the place of hinge attachment to the bolt and the dog allows you to advance the cartridge 11 at a distance greater than the magnitude of the bend of the groove 5 in the transverse plane.

To cock the mechanism carry out the operations described above.

The utility model is a simpler and more compact mechanism, since it can be implemented to the limit of the overall dimensions of the barrel of the mounting gun.
