Description

The invention relates to automatic small arms, namely:

1. to the mechanisms for locking the bore when fired;

2. to trigger mechanisms with automatic firing rate regulator.

Known automatic small arms "PP-2000", the operation of the automation of which is provided by the energy of powder gases acting on the so-called "free shutter". The disadvantage of this weapon is the lack of a mechanism for locking the bore at the time of the shot. As a result, most of the energy is spent pushing the shutter. Another drawback is that the weapon is tied to one type of ammunition, and it is also impossible to use powerful cartridges (7.62TT, 9 mm PAIR, 9 * 21 mm).

It is also known automatic small arms PP "Bushman", in which the task of regulating the rate of automatic firing is solved by means of an electromechanical device located in the weapon control handle, powered by batteries. The disadvantages of this design are: complexity, unreliability, dependence on an external source of energy, as well as the impossibility of placing the magazine in the weapon control handle.

The purpose of the invention is the creation of automatic small arms, devoid of the noted shortcomings, and due to the proposed technical solutions - improving the performance data, expanding the range of tasks to be solved and improving the manufacturability of the product.

This is achieved by the fact that in automatic small arms containing a stamped receiver with side wall folds, a barrel sleeve in which a combat stop and a channel for removing powder gases are made, a barrel sleeve housing in which a locking ledge is made, a bolt with grooves for the barrel folds box, in the front part of which on the axis there is a part of the barrel bore locking mechanism, having a combat and locking ledges, which, under the influence of a return spring and a slider, engage with the barrel clutch and the barrel clutch casing. This ensures the locking of the barrel bore at the time of the shot, and quick-change barrels of various calibers with appropriate magazines ensure the use of various ammunition.

The above goals are also achieved by the presence of a trigger mechanism in automatic small arms, consisting of: a trigger, a trigger axis, which is also the axis of the slide delay, a trigger pull, a trigger, a mainspring, a sear, a single-fire sear, a self-timer, a spring self-timer. The proposed trigger mechanism in operation is similar to the trigger mechanism of a Kalashnikov light machine gun. It differs in that instead of a fixed retarder, an inertial body with a deceleration tooth, a control sector and a shutdown fifth is installed on the sear axis, interacting with the bent end of the mainspring, and the control sector interacts with the rotary cam of the automatic firing rate control flag. When the automatic firing rate control flag is turned, the cam changes the degree of influence of the inertial body on the movement of the trigger. Thus, the problem of changing the rate of automatic firing is solved.

Description of drawings:

The figure 1 shows a general view of an automatic small arms, a longitudinal section (the shutter is in the forward position, the locking mechanism is locked).

The figure 2 shows the firing mechanism, a longitudinal section (the translator is in the "automatic fire" position, the self-timer is on, the trigger is pulled down).

The proposed weapon consists of:

1. Stamped receiver (1) with bends of the side walls, barrel sleeve (2), in which the lugs are made (A), a channel for removing powder gases (B), grooves for installing the sleeve casing (10) and a thread for installing the nut (11) fixing the clutch cover (10) with a locking lug (M) and the barrel (3), the bolt (4) with grooves for the bends of the receiver with an axial channel to accommodate the return-locking spring (9) of the slider (5) with a beveled end and self-timer drive (6). In front of the shutter (4) on the axis (7) there is a part of the barrel bore locking mechanism (8), which is also the control knob (B) for the shutter (4) and the front sight of the sight (C).

2. In the rear of the receiver (1) there is a trigger mechanism containing a trigger (12), the trigger axis (13), which is also the axis of the slide stop (14), the trigger rod (15), the trigger (16 ), mainspring (17), sear (18), single fire sear (19), sear axis (35), self-timer (20), self-timer drive (6), inertial body (21) with deceleration tooth (G), s control sector (E) and the fifth shutdown (F), automatic fire rate control flag (22) with a cam (K), translator (23) with a control sector (P). At the rear end of the receiver (1) there is a butt plate (24) designed to fix the reciprocating-locking spring (9) and fasten the collapsible spring-loaded butt (25), covering the receiver cover (26) and barrel (3) in the folded position. Attached to the lower part of the receiver (1) is a weapon control handle (27) with a channel for installing a magazine (28), a magazine extractor (29) with an axle (30), a spring (31) and an extractor tooth (32), as well as a magazine latch with extraction button (33).

The weapon works like this:

1. Fixation of the part of the locking mechanism in the locked position is carried out by a reciprocating locking spring (9), acting on the part of the locking mechanism (8) through a slider with a beveled end (5).

When loading manually, the shutter control handle (B), which is part of the locking mechanism part (8), is retracted. In this case, the part of the locking mechanism (8) rotates around the axis (7), overcoming the resistance of the reciprocating-locking spring (9), transmitted through the slider with a beveled end (5). When the part of the locking mechanism (8) is turned, its lugs (L) and the locking groove (H) disengage from the lugs (A) of the barrel coupling (2) and the locking ledge (M) of the barrel coupling housing (10). The locking mechanism is open.

With further action on the shutter control handle (B), the shutter (4), compressing the return-locking spring (9), moves back, and then, under the action of the return spring (9), moves forward, pushes the cartridge out of the magazine (not shown) and sends it into the barrel mount (3). The slider (5) under the influence of the reciprocating-locking spring (9), continuing to move forward, with a beveled end presses on the part of the locking mechanism (8), rotates it around the axis (7), engages the lug (L) of the part of the locking mechanism (8 ) with a lug (A) of the barrel clutch (2) and a locking lug (M) of the barrel clutch housing (10) with a locking groove (H) of the locking mechanism part (8). The locking mechanism is closed.

At the same moment, the slider (5) activates the self-timer (20) via the associated self-timer drive (6).

When fired, at the moment the bullet passes through the gas outlet in the barrel, part of the gases rush through the gas outlet channel (B) and act on the lug (L) of the part of the locking mechanism (C), turning it around its axis (7). At the same time, the combat (L) and locking (M) protrusions of the locking mechanism part (8) disengage from the corresponding protrusions of the barrel clutch (2) and the barrel clutch casing (10). Under the influence of the force from the residual gases, directed in the direction opposite to the movement of the bullet, the shutter (4) begins to move in the same direction, compressing the return spring (9). The cycle is repeated.

The design solution of the locking mechanism according to this description allows the details of the locking mechanism (8) to perform several functions:

Locking device of the barrel-bolt system;

• Shutter control knob;

• Front sight sight.

2. The operation of the trigger mechanism is similar to the operation of the trigger mechanism of the Kalashnikov light machine gun (RPK). It differs in that instead of a fixed retarder, an inertial body (21) is installed on the axis of the sear (35) with a deceleration tooth (G), a control sector (E) and a fifth switch-off (G), which interacts with the rotary cam (K) of the automatic speed control flag. fire (22) and the bent end (C) of the mainspring (17). When the translator (23) is placed in the “Automatic fire” position, the sector (P) of the translator (23) releases the sear (18). When the trigger (12) is pressed, it, turning on the axis (13) through the trigger pull (15), turns the sear (18), disengaging it from the cocking (T) of the trigger (16), the trigger under the action of the mainspring (17) begins to rotate around the axis (36), while the trigger tooth (O) interacts with the deceleration tooth (G) of the inertial body (21), overcoming the force of the bent end (C) of the mainspring (17) acting on the inertial body (21) and the moment of resistance of the inertial body (21), turning the body (21) on the axis (35). The trigger (16) receives a slowdown during this interaction. After exiting the interaction, the trigger (16) strikes the striker (37), a shot occurs. The inertial body (21) under the action of the bent end (P) of the mainspring (17), turning on the axis (35), takes its original position. The cycle is repeated. The deceleration obtained by the trigger (16) with the mass of the inertial body (21) and the force of the bent end (P) of the mainspring unchanged, DEPENDS ON THE TIME OF INTERACTION of the tooth (O) of the trigger (16) with the tooth (G) of the inertial body (21), which changes by turning the cam (K) with the flag for controlling the rate of automatic fire (22). Thus, by setting the rotary cam (K) by means of the control flag (22) to a predetermined position before firing, the specified goal is achieved: CHANGING THE AUTOMATIC FIRE RATE.

When the interpreter (23) is placed in the “single fire” position, the interpreter sector (R), acting on the heel of turning off (G) of the inertial body (21), turns it, removing it from interaction with the tooth (O) of the trigger (16). At the same time, the sector (P) of the translator (23) releases the shank (X) of the sear of a single fire (19). Shooting with a single fire is similar to the Kalashnikov light machine gun.

When the translator (23) is set to the “Fuse” position, the sector (P) of the translator (23) locks the sear (18), the sear of a single fire (19), the trigger (12). Shooting and cocking the shutter (4) are blocked.

3. Spring-loaded folding stock (46) in the folded position, without going beyond the dimensions of the weapon, protects the cover of the receiver (26) and the barrel (3) from damage during impacts. The buttstock consists of a stamped T-section body (25) with a spring (38), axles (39) and (40), a butt plate (41) with a spring (42) and a folded position lock (43). The butt (46) is attached to the axis (39) to the butt plate of the receiver, folded up forward, fixed in the folded position by the groove (U) of the casing (10) of the barrel coupling (2). When pressing the latch (43), under the influence of the body spring (38) and the spring (42) of the butt plate (41), the stock (46) is automatically transferred to the unfolded position.

4. Magazine extractor (29) with axle (30), spring (31) and extractor tooth (32). When installing the magazine (45), the protrusion of the magazine (44) engages with the tooth of the extractor (32), advancing it on the axis (30), while the extractor spring (31) is compressed, the magazine stands on the magazine latch (33). When the magazine latch button (33) is pressed, the magazine (45) is released and, under the action of the spring (31), is ejected from the channel of the weapon control handle (28). This solves the problem of quick replacement of the store.

The constructive solution of automatic small arms according to the above description allows:

1) Due to the presence of a mechanism for locking the bore when fired, the use of powerful ammunition (7.62 mmTT, 9 mm PAIR, 9 × 21 mm), and also increases the efficiency of the ammunition used.

2) Due to removable barrels of various calibers and the availability of an appropriate magazine, switch from one type of cartridge to another.

3) Due to the design of the trigger mechanism - to conduct single fire, automatic fire, change the rate of automatic fire, expanding the range of tasks to be solved depending on the conditions of use.

4) Due to the presence of a spring-loaded stock in the folded position, which does not go beyond the dimensions of the weapon, and a swivel forearm - to realize concealed carrying, quick adjustment to the working position and increase ease of use.

5) Due to the magazine extractor and the shutter stop in the rear position after the cartridges are used up, solve the problem of quick reloading when firing and signaling the absence of cartridges in the weapon magazine.

6) Improve the manufacturability of the product, since most of the parts are made by stamping.
