Description

The useful model belongs to weapons technology and can be used in the army, law enforcement agencies, shooting sports.

A pistol is known that contains a frame, a shutter with a percussion trigger mechanism, in the rear part of which there is one hole coaxial with the barrel, and the striker is made in the form of a cylindrical part with a striker in the front part, a protrusion of the combat platoon in the rear lower part for interaction with sear, mainspring, ejector, trigger |F.A. Marmot. "All about pistols and revolvers." Parabellum pistol, Polygon publishing house, 20041.

The closest analogue is a semi-automatic pistol, which contains a body mounted on guides with the possibility of axial movement, a bolt with combat stops, a barrel with corresponding combat stops, a screw pair in the form of a screw protrusion on the barrel and a corresponding groove on the housing, protrusions that limit axial movement barrel, a striker with a mainspring and an ejector with a catch placed in front of the shutter mirror are installed in the shutter. The ejector is made in the form of an L-shaped part, the long side of which is placed in a vertical hole made in the shutter, and the short side faces the breech of the barrel. In the window in the upper part of the bolt on the axis, a limiter is installed, the nose part of which is placed in a longitudinal hole made in the ejector, the catch of the ejector is made along the arc of a circle with an inner diameter equal to the diameter of the edge of the sleeve, the outer part of the catch is made conical, and the corresponding conical surface is made in barrel, a protrusion is made at the end of the conical part of the ejector hook, a corresponding protrusion is made in the barrel with the possibility of their contact, at the end of the barrel closure, a vertical groove is made on the long side of the ejector, the lower surface of which is made with a bevel directed inward, the striker directly behind the striker is made in the shape of a groove and on the lower side, a bevel is made on it in response with the possibility of contact with the bevel of the groove (KO Mo 2186316 С1, 410 3/00, EATA 15/00, 20021.

The disadvantage of this mechanism, like the previous one, is that the diameter of the hole for the firing pin in the shutter is relatively small, limited by the cut-out under the folds of the magazine and the height of the cartridge ejector (for the GSh-18 it can be slightly larger due to the fact that the neck of the magazine is designed for output of two cartridges and has a greater distance between bends). The striker, at the same time, has a correspondingly small diameter and correspondingly low mass. Moreover, the length of the mainspring and the length of movement of the firing pin are reduced due to the formation of the front part of the firing pin

With a fight. The small weight of the striker and its short stroke of movement negatively affect the reliability of the capsule injection, especially when the weapon is contaminated, which can lead to misfires when firing. The vertical movement of the ejector in the front part of the bolt under the action of the bevel of the ejector tooth has increased friction, prone to contamination and, as a result, can lead to the ejector hanging in the upper position. In this position, the launcher cannot reach the capsule and fire. The vertical reflection of the shot casing upwards is not comfortable for the shooter. The gun is disassembled by moving a separate part.

An automatic type fuse that does not exclude a shot if the trigger is accidentally pressed.

The useful model is based on the task of improving both the design of the gun as a whole and its individual parts through new technical solutions that allow due to their integrated use, as well as thanks to the design features of each part, to improve operational characteristics - to reduce the possibility of misfires when firing, to increase reliability pistol, to simplify assembly and disassembly, to increase the safety of the pistol, to eliminate the possibility of an accidental shot, to enable the shooter to manually feel the installed fuse and quickly remove it with the left or right hand without intercepting the handle.

The task is solved by the fact that the pistol, which contains a bolt with a striker-fired mechanism, an ejector, a frame, a trigger guard, a trigger with an automatic fuse, a return spring, according to a useful model, the bolt has at least two holes for installing the striker, and the striker has a body with a striker rod with a striker, one or more inflows for installing one or more mainsprings inconsistent with the striker rod, a protrusion of a combat platoon, an ejector installed in a shutter on an axis, in the front part has a hook, and in the rear part - a protrusion, which is in contact with the upper part of the ejector wick with a spring installed in the hole of the bolt, the lower part of which is made with the possibility of contact with the rod of the striker in its forward position, the frame in the front part has vertical grooves and a longitudinal hole for installing the clutch of the return spring, and the trigger guard has vertical inflow of the gate limiter with protrusions and a longitudinal opening for the passage of the clutch, in which and there is a return spring, a fuse lever is installed in the trigger on the axis, made with the possibility of limited rotation and 60 locking of the trigger.

The claimed pistol has improved operational characteristics: the possibility of misfires during shooting is reduced; increased reliability; simplified assembly and disassembly; enhanced security, excluding the possibility of an accidental shot; this allows the shooter to manually feel the installed fuse and quickly remove it with the left or right hand without intercepting the handle.

The gun contains a shutter 1 (Fig. 1, Fig. 2, Fig. 5), which has a hole 2 made on the rear side of the shutter 1 for the largest possible length D, a hole C at a distance H below the hole 2, coaxial with the barrel, and a cutout 4, in which the striker body 5 is installed (Fig. 3, Fig. 4). The cutout 4, made to the length of the DI, ensures the reciprocating movement of the striker body 5. The hole 3, in the front part, has a through hole 6 of a smaller diameter. The body of the striker 5 has an elongated projection 7 with a hole 8 and has the possibility of reciprocating movement in the hole 2. In the hole 8 there is a mainspring 9. The body of the striker 5 below the hole 8 at a distance H has a rod 10 with a striker 11 formed on its front end. The striker body 5, in the rear lower part, has a protrusion of the combat platoon 12, which interacts with the combat platoon 13 of the whisperer 14, installed in the rear part of the frame 15. In the rear part of the shutter 1, a limiting stop 16 is installed, which limits the movement of the combat spring 9 back. In shutter 1, on axis 17 (Fig. 5), an ejector 18 is installed, the front part 19 of which interacts with the outer sleeve 20, and the rear part 21 - with the upper part of the spring-loaded rod of the ejector wick 22, located in hole 23 of shutter 1. Hole 23 of shutter 1 is connected with a hole From the striker rod 10. The lower part 24 of the rod of the ejector crimp 22 interacts with the striker rod 10 in its front position and prevents the lifting of the front part 19 of the ejector 18 and the loss of the sleeve 20 when the shutter 1 moves back. In the front part of the frame 15 (Fig. b), vertical grooves 25 are made, interacting with the vertical protrusions 26 of the shutter limiter 27 of the trigger guard 28 (Fig. 7, Fig. 1, Fig. 9.

Fig. 10). In the front lower part of the frame 15, a hole 29 is made, and in the limiter of the shutter 27 coaxially with it - a hole 30, in which the clutch 31 of the return spring 32 is located.

In the trigger guard 28 (Fig. 9, Fig. 10), a trigger 34 is placed on the axis 33, on which the fuse lever 36 is placed on the axis 35 on the left and right side of the trigger 34. The fuse 36 has the possibility of limited rotation on the axis 35. Left the side of the trigger bracket 28 has a cut-out 37 in which the safety protrusion 38 is placed when the trigger is turned when "removed" from the fuse.

The gun functions as follows.

To load the weapon, the shutter 1 is moved to the rearmost position until it stops in the shutter limiter 27 (Fig. 1, Fig. 3). In this position, combat platoon 12 of striker 5 will go behind combat

From platoon 13 whispered 14 and will let him go. When the shutter 1 moves forward, under the action of the return spring 32, the firing pin 5 is held on the combat platoon 13 by the whisperer 14, and the shutter 1 compresses the combat spring 9, affecting its rear end with the stop 16. When the shutter 1 moves forward, the cartridge is sent into the chamber, and the front part 19 of the ejector 18 goes beyond the edge of the sleeve 20. The crimp 22 of the ejector 18 under the action of the spring is in the upper position, and its lower part 24 does not prevent the movement of the rod 10 with the striker 11 forward. When the trigger 34 is pressed, the whisperer 14 releases the combat platoon 12 of the striker body 5. The front end of the combat spring 9, installed in the hole 8 of the striker body 5, acts on the striker 5 and moves it forward along the hole 2 and the cut-out 4 of the bolt 1 to the distance DI. At the same time, the rod of the striker 10, installed in the housing 5, also moves forward along the opening C of the shutter 1 and blocks the possibility of the wick 22 going down. The ejector 18 thus becomes locked. During the further movement of the firing pin, the firing pin 11 goes forward through the through hole b and breaks the cartridge capsule. A shot is fired.

When the shutter 1 moves back, the front part 19 of the ejector 18 hard pulls the sleeve 20, as the wick 22, resting with the lower part 24 on the striker rod 10, prevents the rotation of the ejector 18 around the axis 17 and the ejection of the ejector 18 from the edge of the sleeve 20 until it is reflected.

Limiting the rollback of the shutter 1 is carried out by the protrusion of the shutter limiter 27 of the trigger 28. The trigger 28 is inserted from the bottom of the frame 15 along the grooves 25 by the protrusions 26 of the shutter limiter 27 (Fig. 7, Fig. 8). The clutch 31 with an inserted return spring 32 is placed in the opening 29 of the frame 15 and the opening 30 of the limiter shutter 27 of the bracket 28, fixing them in the assembled state.

Production of a shot is possible when the fuse lever 36 is turned down (Fig. 9, Fig. 10).

In this case, the projection 37 of the fuse 36 when the trigger 34 is pressed and its rotation around the axis 33 will enter the cutout 38 and will not prevent the rotation of the trigger 34 to fire. In the upper position of the fuse lever 36 (Fig. 10), the gun is placed on the fuse. The projection 37 rests against the trigger 28 and prevents the trigger 34 from returning to fire.
