Description

The utility model relates to the field of weapons technology, namely to handguns of limited destruction.

The design of the P4 pistol "Storm" of the company "Beretta" / "Fedoseev SL," All About the Pistol ", 2003, Moscow, ACT Publishing House LLC, pp. 205-243 / with locking by turning the barrel with the entry is known a locking protrusion into the extraction window and a spring-loaded barrel closure against which the barrel abuts during a rollback, thereby damaging the barrel’s impact on the frame when unlocking. This design allows partial shock absorption when unlocking, but does not provide shock attenuation at the extreme rear point of shutter rollback and when the shutter is in the front position.

Also known is the design of the Glock pistol company Austria / Fedoseyev S.L., "All About the Pistol", 2003, M., ACT Publishing House LLC, pp.205-243 / with a trigger trigger mechanism with cocking drummer and setting it to whisper at the end of the shutter lag period.The disadvantage of this gun is the low manufacturability, considerable weight, low accuracy of firing. This solution is chosen as a prototype.

The objective of this utility model is to increase the manufacturability of a pistol, increase firing accuracy, reduce the weight and cost of manufacturing, as well as use it as a traumatic weapon with limited use of live ammunition (in accordance with the current "Law on Weapons").

The problem is solved due to the fact that the gun contains a frame with a handle made of plastic, metal guides are installed in the frame to move the slide along them and a locking part with guides for the barrel. Also, the gun contains a barrel mounted on the guides of the locking part of the frame, a slide with a bolt sliding on the metal guides of the frame (metal guides are implanted in the frame). The barrel contains a chamber, a chamber and a channel. The trunk consists of two parts interconnected coaxially by a threaded connection. In the first part of the barrel there is a chamber and pre-chamber, and in the second channel of the barrel. Starting from the end from the side of the prechamber, the first part of the trunk has a section of long Ly and an outer diameter Dy

Ly≤Lп,

Dpr <Dy <Dc,

where Ly is the length of the section, Lп is the length of the prechamber, Dс is the outer diameter of the barrel, Dpr is the diameter of the prechamber, Dy is the diameter of the section.

Part of the length of this section, starting from the end, is threaded. On the other part of this section, one or more non-through annular grooves (grooves) are made. In the second part of the barrel, a cylindrical recess is made coaxially with the bore of the barrel, having a section with a thread at the end of the recess, the recess corresponds to the diameter of the thread and the length of the section of the first part of the barrel and is a mate for threaded connection with the first part of the barrel, with Dк <Dпр <Dy < Dп, where Dchannel - diameter of the bore. In the bolt is a striker with a striker and a striker spring. The trigger mechanism is placed in a frame, a nest for a magazine is formed in the handle, the slide is made of aluminum alloy. On the lower side of the front of the slide, a U-shaped groove is made for subsequent placement of the barrel, and the generatrix of this groove is associated with a hole in the front of the slide. On the lower side of the breech (back) part of the slide, a longitudinal groove is made in the form of a truncated circle to accommodate the shutter, and the distance between the edges of this groove in the cross section is less than the diameter of the circle. The shutter is made in the form of a truncated cylinder and placed in the groove of the breech of the slide with a rigid fixation. On the first part of the barrel there is a locking protrusion for fixing in the groove of the locking part of the frame and a guiding protrusion located at the end of the breech of the barrel, and in the guide protrusion an inclined U-shaped groove is made, the generatrix of which is mated to the hole of the barrel chamber. A protrusion with an inclined U-shaped groove, paired with a U-shaped groove of the guide protrusion, is made on the locking part.

The technical result that this utility model aims to achieve is to increase the manufacturability of the pistol, reduce weight, increase firing accuracy, limit the possibility of firing metal shells, as a result of which they are given a specific kinetic energy of more than 0.5 J / mm.

The technical result is achieved due to the fact that:

- the gun contains a frame with a handle made of plastic, a barrel mounted on the guides of the frame, a slide with a bolt sliding along the guides of the frame, a firing pin with a striker and a firing spring are located in the bolt, metal guides are installed in the frame to move the slide and locking a part with guides for the barrel, the trigger mechanism is placed in the frame, a magazine slot is formed in the handle;

- the barrel consists of two parts connected by a threaded connection, with a chamber and a pre-chamber located in one part, and in the second bore of the barrel. The diameter of the barrel is smaller than the diameter of the bullet. Thus, when fired, the bullet passes through the pre-chamber and abuts against the protrusion formed by the transition of the larger diameter of the pre-chamber to the smaller diameter of the barrel, resulting in the accumulation of energy of powder gases, as a result of which the bullet is deformed, passes into the channel of the barrel and gains more kinetic energy. In the section of the first part of the trunk, non-through annular grooves (grooves) are made. The depth, width, location, shape and number of these grooves (grooves) can be different and are selected empirically in such a way that when using authorized ammunition for traumatic action (for example, a cartridge with a rubber bullet), the structure can withstand standard pressure loads in the barrel without destroying the structure, however when trying to shoot a cartridge of increased power (live cartridge), not provided for by this design, the structure is destroyed in the locations of the grooves (proto ) And separation of the two parts of the barrel, which entails a failure of the weapon and the impossibility of its use.

- the slide is made of aluminum alloy, which helps to reduce the weight of the structure as a whole;

- on the bottom side of the front of the slide made U-shaped groove for subsequent placement of the barrel, and the generatrix of this groove is associated with a hole in the front of the slide. The selection of metal in the form of a U-shaped groove simplifies the complex technological process of sampling in comparison with the analogue. The forming groove is an additional support for the barrel surface, which allows you to distribute the transverse components of the recoil forces during firing over the entire area of contact with the slide (i.e., to extinguish excess vibration), and as a result increase the accuracy of shooting.

- a longitudinal groove in the form of a truncated circle for placing the shutter is made on the lower side of the rear (breech) part of the slide, and the distance between the edges of this groove in the cross section is smaller than the diameter of the circle, the shutter is made in the form of a truncated cylinder and placed in the groove of the breech part of the slide with rigid fixation . The ability to make the shutter in the form of a separate part makes it possible to simplify the procedures for increasing the wear resistance of the material (nitriding, hardening) and to produce them only in those areas of the design where it is necessary, without subjecting these procedures to non-target areas. This undoubtedly simplifies the process and reduces the risk of damage to non-target areas due to fragility.

- a locking protrusion is made on the barrel for fixing in the groove of the locking part of the frame and a guiding protrusion located at the end of the breech of the barrel, the inclined U-shaped groove being made in the guide protrusion, the generatrix of which is mated to the hole of the barrel chamber, the protrusion is made on the locking part U-shaped groove mated to the U-shaped groove of the guide protrusion.

The execution on the barrel of the locking protrusion allows you to fix the barrel from displacement when firing relative to the frame. Moreover, unlike the analogue, where during the shot the barrel is shifted relative to its position before the shot to decompose the recoil force into components and reduce recoil in the hand, in this solution the barrel is fixed and remains in place after the shot. In analogue, the decomposition of force contributes to a significant displacement of the pistol from the trajectory of the shot, which complicates aiming at the target during the second shot and reduces the accuracy of fire. In the present utility model, barrel locking during firing allows you to direct most of the recoil force component to the recoil of the bolt, which makes it possible to use cartridges of lower power and increases accuracy and accuracy of fire. The implementation of the inclined protrusion on the barrel and the associated protrusion of the locking part serves to guide the cartridge from the magazine into the chamber of the barrel.

The barrel contains a chamber 16, a chamber 17 and a channel 18, in the section of the first part 22 of the barrel one or more annular non-through grooves (grooves) 19 and thread 20 are made. In the second part of the barrel 21 a cylindrical recess with a thread is made, which is a mating part for a threaded connection with the first part.

The threaded connection of both parts is made with a tight combination of the external and internal forming surfaces of both parts without gaps.

When firing an unauthorized cartridge (with a power higher than that provided for by the design), the cartridge is fed into the barrel chamber 16, then a shot is fired, the bullet passes to the pre-chamber 17 and abuts against the protrusion formed by the transition of the larger diameter of the pre-chamber to the smaller diameter of the barrel 18, resulting in the accumulation of powder energy gases in the pre-chamber 17. Due to the increased pressure in the pre-chamber 17, the connection of the two parts of the barrel in the places of weakening of the structure in the form of non-through grooves (grooves) 19 is destroyed which leads to the impossibility of further exploitation of weapons.
