Description

GUN

The invention relates to weapons technology and can be used in the army, law enforcement, shooting sports.

A pistol is known, containing a frame, a bolt with a striker trigger mechanism, in the back of which there is one hole coaxial with the barrel, and the drummer is made in the form of a cylindrical part with a striker in the front, a cocking protrusion in the rear lower part to interact with the sear , mainspring, ejector, trigger guard [F.A. Babak. "All About Pistols and Revolvers". Pistol "Parabellum", publishing house "Polygon", 2004].

Closest to the invention is a semi-automatic pistol, containing a body mounted on guides with the possibility of axial movement, a bolt with lugs, a barrel with reciprocal lugs, a screw pair in the form of a screw protrusion on the barrel and a groove in response to it on the body, protrusions that limit axial movement barrel, a striker with a mainspring installed in the gate and an ejector with a hook placed in front of the gate mirror. 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 bolt, and the short side is facing the breech breech. A limiter is installed in the window in the upper part of the shutter on the axis, the nose of which is located in a longitudinal hole made in the ejector, the ejector hook is made along an arc of a circle with an inner diameter equal to the diameter of the rim of the sleeve, the outer part of the hook is made conical, the mating cone surface is made in the barrel , a protrusion is made at the end of the conical part of the ejector hook, a reciprocal protrusion is made in the barrel with the possibility of their contact at the end of the locking of the barrel, 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 from the bottom side it has a reciprocal bevel with the possibility of contact with the bevel of the groove [RU No. 2186316 Cl , F41C 3/00, F41A 15/00, 2002].

The disadvantage of this mechanism, like the previous one, is that the diameter of the hole for the striker in the bolt has a relatively small diameter, limited by a cutout for the bends of the magazine and the height of the cartridge ejector (for GSh-18 it can be somewhat larger due to the fact that the neck of the magazine is designed for the exit of two cartridges and has a greater distance between the bends). The drummer, at the same time, has a correspondingly small diameter and, accordingly, a small mass. Moreover, the length of the mainspring and the length of movement of the striker is reduced due to the formation of the front part of the striker with the striker. The small mass of the striker and its short travel stroke negatively affect the reliability of the primer, 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 shutter under the action of the bevel of the ejector tooth has increased friction, is subject to contamination and, as a result, can lead to the ejector hanging in the upper position. In this position of the ejector, the striker cannot reach the primer and fire a shot. The vertical reflection upwards of the spent cartridge case is not comfortable for the shooter. The gun is disassembled by moving a separate part. Automatic type fuse, which does not exclude a shot if the trigger is accidentally pressed.

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

The problem is solved by the fact that in a pistol containing a bolt with a striker trigger mechanism, an ejector, a frame, a trigger guard, a trigger with an automatic fuse, a return spring, according to the invention, the bolt has at least two holes for installing the drummer, and the drummer has housing with a striker rod with a striker, one or more lugs for installing one or more mainsprings that are not aligned with the striker rod, cocking protrusion, the ejector installed in the bolt on the axle has a hook in the front part, and a protrusion in the rear part that contacts with the upper part of the ejector arm with a spring installed in the bolt hole, the lower part of which is made with the possibility of contact with the striker rod in its forward position, the frame in the front part has vertical grooves and a longitudinal hole for installing the return spring clutch, and the trigger guard has a vertical tide limiter a bolt with projections and a longitudinal hole for the passage of the clutch, in which the return spring is located, in the trigger on the axis there is a safety lever, made with the possibility of limited rotation and blocking of the trigger.

In the inventive gun improved performance: reduced the possibility of misfires when shooting; increased reliability; simplified assembly and disassembly; enhanced security with the exception of the possibility of an accidental shot; the shooter is given the opportunity to manually feel the installed fuse and quickly remove it with his left or right hand without intercepting the handle.

The gun contains a shutter 1 (Fig.1, Fig.2, Fig.5), having a hole 2, made from the back side of the shutter 1 to the greatest possible length D, the hole 3 at a distance H below the hole 2, coaxial with the barrel, and cutout 4 , in which the body of the drummer 5 is installed (Fig.Z, Fig.4). Cutout 4 is made to length D1 providing reciprocating movement of the drummer body 5. Hole 3, in the front part, has a through hole 6 of smaller diameter. The body of the impactor 5 has an elongated protrusion 7 with a hole 8, which has the possibility of reciprocating movement in the hole 2. The mainspring 9 is located in the hole 8. The body of the impactor 5 below the hole 8 at a distance H has a rod 10 with a striker 1 1 formed at its front end The body of the striker 5, in the rear lower part, has a protrusion of the cocking 12, which interacts with the cocking 13 of the sear 14, installed in the rear of the frame 15. In the rear part of the bolt 1, a limit stop 16 is installed, which limits the movement of the mainspring 9 back. In the gate 1 on the axis 17 (Fig.5) installed ejector 18, the front part 19 of which interacts with the rim of the sleeve 20, and the rear 21 - with the upper part of the spring-loaded rod of the yoke of the ejector 22, located in the hole 23 of the shutter 1. The hole 23 of the shutter 1 is reported with hole 3 of the striker rod. The lower part 24 of the ejector yoke rod 22 interacts with the striker rod 10 in its forward position and prevents the front part 19 of the ejector 18 from rising and the sleeve 20 from being lost when the shutter 1 moves back. In front of the frame 15 (Fig.6) is made of vertical grooves 25, interacting with the vertical protrusions 26 of the shutter stop 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 shutter limiter 27, a hole 30 is coaxial with it, in which the clutch 31 of the return spring 32 is located.

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

The mechanism works as follows.

To load the weapon, the shutter 1 is retracted to the rearmost position until it stops against the shutter stop 27 (Fig. 1, Fig.3). In this position, the combat platoon 12 of the drummer 5 will go behind the combat platoon 13 of the sear 14 and release it. When the bolt 1 moves forward, under the action of the return spring 32, the drummer 5 is held on the cocking 13 of the sear 14, and the bolt 1 compresses the mainspring 9, acting on its rear end with the stop 16. With further movement of the bolt 1 forward, the cartridge is sent into the chamber, and the front part 19 of the ejector 18 goes beyond the rim of the sleeve 20. Gnetok 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 sear 14 releases the combat platoon 12 of the drummer body 5. The front end of the mainspring 9, installed in the hole 8 of the drummer body 5, acts on the drummer 5 and moves it forward along the hole 2 and cutout 4 of the bolt 1 to a distance D1. In this case, the striker rod 10, installed in the housing 5, also moves forward along the hole 3 of the shutter 1 and blocks the possibility of the yoke 22 going down. The ejector 18 thus becomes blocked. With further movement of the drummer, the striker 11 comes out through the through hole 6 forward and breaks the primer of the cartridge. There is a shot.

When the shutter 1 moves back, the front part 19 of the ejector 18 rigidly removes the sleeve 20, since the yoke 22, resting with the lower part 24 against the rod 10 of the drummer, prevents the ejector 18 from turning around the axis 17 and the ejector 18 from the rim of the sleeve 20, until it is reflected.

The recoil of the shutter 1 is limited by the protrusion of the shutter limiter 27 of the trigger guard 28. The trigger guard 28, the protrusions 26 of the shutter limiter 27 is inserted from the bottom of the frame 15 along the grooves 25 (Fig.7, Fig.8). The clutch 31 with the inserted return spring 32 is placed in the hole 29 of the frame 15 and 30 of the limiter 27 of the bracket 28, fixing them in the assembled position.

The production of a shot is possible when the safety lever 36 is turned down (Fig.9, Fig.10). In this case, the protrusion 37 of the fuse 36, when the trigger 34 is pressed and rotated around the axis 33, will enter the cutout 38 and will not prevent the trigger 34 from turning to fire a shot. In the upper position of the safety lever 36 (Fig.10) the gun is on safety. The protrusion 37 rests against the trigger guard 28 and prevents the trigger 34 from turning to fire a shot.
