Abstract

FIELD: weapons and ammunition.

SUBSTANCE: small-arms comprise the driving automation member, the housing including the barrel receiver, the trigger mechanism consisting of the main sear, the single-fire sear, the trigger, and the sears spring. The single-fire sear is arranged on the main sear with the possibility of the spring impact on the single-fire sear and of turning the main sear to its original position upon the trigger release.

EFFECT: reducing the dimensions of the single-fire mechanism without reducing the strength of its parts.

Description

The invention relates to small arms devices and can be used for their modernization, for example, when remaking military weapons into civilian, when it is necessary to exclude the possibility of automatic firing.

Known 7.62 mm machine gun (submachine gun) arr. 1941 (Shpagin submachine gun). The submachine gun contains: a receiver, a trigger, a trigger spring, a trigger, a trigger spring, a trigger pull, a trigger spring, a disconnector. Ensuring a single fire of the device occurs due to the separation of the trigger with the trigger lever with the trigger pressed. (Book. 7.62 mm AUTOMATIC MACHINES (submachine guns) model 1941 and model 1943, second edition, revised, MILITARY PUBLISHING HOUSE OF THE MILITARY MINISTRY OF THE UNION OF THE SSR, Moscow-1951.) The device is taken as the closest prototype by essential features.

The disadvantage of this weapon is the size of the trigger assembly caused by the presence of the trigger spring, trigger of the trigger, spring of the trigger and disconnector.

The objective of the invention is: to reduce the size of the mechanism of a single fire without reducing the strength of its parts.

The technical result obtained by carrying out the invention consists in installing a trigger mechanism consisting of a main sear, a single fire whisper, a trigger and a whisper spring.

The specified technical result is achieved in that in small arms containing a leading link of automation, a housing including a receiver, a trigger mechanism consisting of a main sear, a single fire whisper, a trigger and a spring whisper, the new one is that the single fire whisper is located on the main sear with the possibility of the spring acting on the sear of a single fire and turning the main sear to its original position when releasing the trigger.

The leading link in automation is the shutter.

The leading link in automation is the slide frame.

The installation of the trigger mechanism, consisting of the main sear, the sear of the single fire, the trigger and the spring of the sear, provides a reduction in the size of the mechanism of a single fire without reducing the strength of its parts.

In FIG. 1 shows a device of small arms, a general view, the position of units on a combat platoon; in FIG. 2 shows a small arms, the position of the parts when fixing the leading link of automation by the sear of a single fire; in FIG. 3 shows the device of small arms at the moment of disengagement of the leading link of automation with the sear of a single fire.

Small arms contain: a housing 1, including a receiver, a driving link of automation 2, which is a bolt or bolt frame, a return-fighting spring 3, a trigger 4, a main sear 5, an axis of the main sear 6, a sear of a single fire 7, an axis of a single fire whisper 8, the spring whispered 9.

The device operates as follows.

Before the shot, the leading link of automation 2 (shutter or bolt frame) is in the cocked position, being held by the main sear 5. When you press the trigger 4, the main sear 5 is turned, when the moment comes when the protrusion of the main sear 5 goes out of interaction with the protrusion on the lead link automation 2 (shutter or bolt frame), due to the reciprocating spring 3, the leading link automation 2 (shutter or bolt frame) begins to move in the direction of the extreme front position. When the leading link of automatics 2 (shutter or bolt frame) arrives in the extreme forward position, a shot occurs and the rollback of the leading link of automatics 2 (shutter or bolt frame) begins. During the rollback, the leading automation link 2 (shutter or bolt frame) with its protrusion lowers the sear of the single fire 7 down, and having run over the ledge of the whisper of the single fire 7 starts to move to its original position due to the action of the reciprocating spring 3. During the overrun of the leading link of automation 2 (shutter or bolt) the whisper of a single fire 7 turns upward on the axis of the sear of a single fire 8 due to the spring whisper 9. The turn of the sear of a single fire 7 is limited by the axis of the main sear 6. When rolling, the protrusion of the leading link of the automatic Matic 2 (shutter or bolt frame) rests on the protrusion of the sear of a single fire 7. When releasing the trigger 4, the main sear 5 will turn on the axis of the main sear 6 through the transmission of force from the spring whispered 9 through the axis of the sear of a single fire 8. At the same time, the protrusion of the lead the link of automation 2 (shutter or bolt frame) will disengage with the protrusion of the sear of a single fire 7. The leading link of automation 2 (shutter or bolt frame) will begin to move towards the extreme forward position until it stops against the protrusion of the main sear 5. For production Island the next shot you need to press the trigger again 4.

The design and operation of the remaining mechanisms of small arms is not described due to their well-known.

Claims (1)

Small arms containing the leading link of automation, a housing including a receiver, a trigger mechanism consisting of a main sear, a single fire whisper, a trigger and a spring whisper, characterized in that the single fire whisper is located on the main sear with the possibility of a spring acting on the single sear fire and turning the main whisper to its original position when releasing the trigger.
