Description

The utility model relates to the field of weapons technology and can be used in samples of small arms.

The following technical solutions are known from the prior art.

The well-known Gerasimenko pistol, in which 7.62 mm case-free cartridges are used for firing, in which the powder propellant charge is located in the pool itself. The bullet is chiseled steel, at the back it has a cavity for charging and an internal thread into which a brass capsule sleeve is screwed. A capsule composition is pressed into the sleeve, coated on the outside with varnish or copper foil. The flange of this sleeve also serves to cut into the grooves of the barrel, that is, it performs the function of a leading belt. After pricking (initiation), the capsule burns out, igniting the charge inside and releasing a hole occupied by itself for the expiration of powder gases from the inside of the bullet cartridge. (https://ru.wikipedia.org/wiki/%D0%92%D0%90%D0%93-73).

Also known is the VEC-91 rifle from Voere (Austria), which uses a cartridgeless 5.7 or 6 mm caliber cartridge with electric ignition. The ignition energy is provided by an electric battery located in the butt of the rifle. The design with manual reloading dramatically reduces the requirements for both the mechanical strength of the cartridge and its resistance to high chamber temperatures, however, the high cost of the rifle and ammunition for it makes the Voere VEC-91 a rather expensive exotic toy than a mass weapon. VEC-91 does not provide any real advantages over conventional hunting rifles of similar calibers (http://weaponland.ru/publ/bezgilzovoe_strelkovoe_oruzhie/17-1-0-356).

The idea of a weapon with shellless ammunition is currently embodied in many types of shooting systems that use different types of bullet shells when placing a powder (throwing) charge in their hollow interior (for example, VAG-73 Gerasimenko, M-76 submachine gun , USA, Benell, Italy), and on the outside in the form of a solid coating (for example, the company VOERE, Austria). All warheads of these and similar systems are complex in design and include a capsule, an expensive and time-consuming element of known rifle systems.

The technical problem solved by the claimed utility model is to simplify the design of sleeveless small arms and increase the functional reliability of shooting by eliminating from the design such labor-intensive elements as a capsule, hammer, trigger, fuse.

The technical result of the utility model is to increase the functional reliability of a shell of a shellless self-loading pistol during storage and shooting.

The specified technical result is achieved due to the design of a sleeveless self-loading pistol, including a barrel, a bolt, a trigger mechanism, a handle with an ammunition magazine, an electric chain for igniting a powder charge placed in a bullet case, and the electric circuit consists of a battery connected by means of lead wires through a button short circuits with spring-loaded contactors passing through the barrel and meshing with grooves on the outer surface of the bullet body with a tungsten filament, replennoy inside.

The bullet case includes a metal case with a hollow space, closed by a cap, to accommodate the powder charge and tungsten filaments, while its outer surface is covered with an electrical insulating composition, except for the grooves, which include contactors, which also protects the shell of the shell from corrosion.

The indicated result is achieved by the structure of a bullet projectile with a tungsten filament inside the case, which acts as an igniter of the warhead instead of the capsule and heated when the electric circuit of the ignition of the warhead is heated when the electrical circuit is closed. In this case, the shell of the bullet shell is tightly closed by a cap that is discharged during firing, and the coating of the shell of the shell with electrical insulating material also protects the shell from corrosion, which eliminates the problems of dampening the warhead or its ignition during storage and firing, as well as oxidation of the tungsten alloy of the thread, which ensures the elimination of failures shell when shooting.

The following is illustrated by drawings, which depict:

FIG. 1 - structural diagram of the gun.

FIG. 2 is a section A-A of FIG. one.

FIG. 3 is a diagram of the trigger mechanism.

FIG. 4 is a circuit diagram for igniting a warhead.

FIG. 5 - bullet shell.

The utility model includes a barrel 1, a trigger, a bolt and a device for igniting a warhead.

The shutter consists of a casing 2, made with the ability to freely move over the barrel back and forth during the up and down, pusher 3 with a spring 4, mounted on the rod 5.

The trigger mechanism includes a trigger guard 17, supported by springs 13 and connected with a lever 16 that pivots on the hinge 18 to impact the rod 14 when firing it down with the hook 12, which serves to hold the bolt in the cocking state, entering the cutouts of the lower edges of the casing 2.

A device for electric ignition of a warhead, which includes an electric battery 7, a tungsten filament 23 placed inside a bullet projectile 6, contactors 8, an electric circuit closure button 10. In a neutral state of a weapon, the electric circuit is open within the barrel 1 (between two contactors 8) and under the closure button 10 electrical circuits. The bullet projectile is made of a steel body, coated externally with an insulating composition, except for the grooves 26 around the circumference of the bullet body, which are used to enter the steel contactors 8, so that the bullet body closes the torn section of the electrical circuit within the barrel 1. The bottom of the bullet projectile 6 is tightly closed with a cap 25.

The gun also includes a magazine box 19 with ammunition and a camera for receiving bullet caps 11.

This weapon works as follows.

To bring the pistol into a combat platoon position, the bolt is retracted to the limit back with the hook 12 catching. In this case, the usual mechanism of action is the supply of an ammunition from the magazine box 19 to the front part. The act of firing includes:

a) pressing the trigger bracket 17, while the lever 16, turning around the hinge 18, presses on the lower end 15 of the rod 14, moving it down, and the hook 12 rigidly connected to it, leaving the cutouts 9 in the lower edges of the casing 2, releases the shutter and he rushes forward under the action of the mainspring 4, delivering a bullet shell into the barrel with his pusher 3, while the body of the ammunition, moving on the spring-loaded contactors 8, slightly protruding above the lower line of the barrel, heats them until they enter the grooves with the ammunition locked and locked;

b) pressing the button 10 - in this case, the circuit is completely closed, at which the voltage from the battery 7 is supplied through the contactors 8 to the tungsten filament 23 with its heating and ignition of the warhead 24 (for example, gunpowder) inside the bullet projectile 6. The resulting powder gases are pushed a bullet shell from the barrel 1, acting on the pusher 3, taking the entire bolt back, compressing the mainspring 4, to the state of the cocking platoon, and the cap 25, pressing against the end of the pusher 3 under pressure of gases, comes to the end with it and falls into the receiving kame ru 11.

Production of firing from this gun can be carried out in the following modes:

a) fixed-single shots - when you press the trigger guard in the back of the handle and subsequent presses on the button in the front of it, each shot - when you double-click on these parts in succession;

b) single shots with the possibility of a double shot - when you press the trigger guard and subsequent subsequent presses of the button at a fast pace;

c) a series of automatic shots - when you press the trigger and the button, holding them in short intervals. This mode is not rational and can be used in exceptional cases. Nevertheless, the nature of the trigger allows the gun to be used in automatic mode if large magazines are inserted into the handle of the gun. However, at this stage, the utility model provides for the preferable use of this weapon in single-shot mode. The introduction of elements such as a cap and a tungsten thread into the design of a warhead determines the nature of the whole concept of the pistol, which allowed for simpler forms in all nodes of the weapon. Wherein:

1) such a significant element as a capsule is abolished - expensive and difficult to manufacture, its one-time appointment is replaced by a permanent electric ignition device.

2) the drummer, trigger, fuse and other details complex and labor-consuming to manufacture have been eliminated;

3) closing the bullet projectile with a cap protects the powder charge placed in it from dampness or ignition, especially in cases where it is used externally, in the form of solid coatings;

4) when firing, pressing the button for closing the circuit is certainly smoother and faster - without the disruption obtained in conventional types of small arms with the trigger, and this should be a factor in more accurate shooting. At the same time, opportunities are increasing for a slight increase in the rate of fire - according to preliminary estimates, 1.5-2 times.
