Description

The invention relates to small arms and can be used, for example, in pistols.

Option 1 of the gun locking mechanism.

The closest analogue to the claimed invention is the Walter R 99 pistol locking mechanism, which contains: a tide, a return spring axis, a return spring, a pistol frame with guides and a return spring stop, a barrel with the possibility of a short reciprocating movement, combat protrusions engaged with their corresponding combat grooves made on the inner surface of the shutter-casing provided with guides, a means for locking the shutter-casing relative to the barrel, including an oblique groove and a guide pin, (authors V.I. Pilyugin, M.B. Ingerleib, The book "Pistols and revolvers, selection, design, operation", publishing house "book house" 2010 Moscow, part 1, Fig. 19., Website on the Internet: zonwar> Pistol Walther R 99 ...).

This device is the closest to the claimed and can serve as a prototype.

The disadvantage of the known locking mechanism of the pistol is that the unlocking of the shutter-casing and the barrel locked relative to each other with the help of the corresponding combat grooves and engagement lugs occurs due to the transverse movement of the breech breech down when the barrel rolls back.

This disadvantage is due to the fact that the tide with an oblique groove is located on the outer underside of the barrel, under the breech. Therefore, during the rollback of the barrel to unlock it, the oblique groove of the barrel tide interacts with the guide pin of the pistol frame. As a result, the breech breech moves transversely down. There is a rotation of the longitudinal axis of the trunk (skew). The warp deflects the barrel from the direction of the target. This negatively affects the accuracy of fire from a pistol.

The present invention solves the problem of increasing the accuracy of fire from a pistol by eliminating the transverse movement of the breech breech (skew) during its short longitudinal movement (rollback), when the locking mechanism of the gun is operating.

To achieve this technical result in the proposed locking mechanism containing a tide, an axis of a return spring, a return spring, a pistol frame with guides and a return spring stop, a barrel with the possibility of a short reciprocating movement, lugs engaging with their corresponding combat grooves, made on the inner surface of the shutter-casing, equipped with guides, a means for locking the shutter-casing relative to the barrel, including an oblique groove and a guide pin, it is proposed to additionally provide the boss with lugs and perform it together with the axis of the return spring, which is provided with a clutch located on the axis between the boss and return spring, additionally provide the barrel with guides and a cutout made on the lower outer side, in which to place the tide of the axis of the return spring, while the engagement of the lugs of the tide of the axis of the return spring with the corresponding combat grooves of the shutter-casing is realized be a means of locking the shutter-casing relative to the barrel, providing a misalignment of the axis of the return spring with a tide during a short, joint with the barrel, translational movement of the axis of the return spring.

Distinctive features of the proposed pistol locking mechanism from the above-mentioned well-known locking mechanism of the pistol, which is closest to it, is that the engagement of the combat projections of the tide of the return spring axis with the corresponding combat grooves of the shutter-casing is implemented by means of locking the shutter-casing relative to the barrel, which ensures the axis of the return spring is skewed. springs with a tide during a short, joint with the barrel, translational movement of the axis of the return spring.

This is possible due to the fact that the tide is additionally provided with lugs and is made together with the axis of the return spring, which is equipped with a clutch placed on the axis between the tide and the return spring, the barrel is additionally equipped with guides and a cutout made on the lower outer side, in which the tide of the axis is placed return spring.

Due to the presence of these distinctive features, the barrel of a pistol, when firing a shot, carries out only a rectilinear movement along its longitudinal axis and does not deviate from the direction of the target. This is due to the absence in its movement of the transverse movement of the breech breech (skew), which deflects the barrel from the direction to the target. As was indicated in the achieved technical result.

In this case, the oblique groove 2 of the tide interacts with the guide pin 3 of the pistol frame and the tide 1, located in the cutout of the barrel 14, moves down transversely. As a result of this movement, the lugs 11 of the tide of the axis of the return spring disengage from the corresponding combat grooves 12 of the shutter-casing 8. The barrel 7 rests with its guides 13 against the back movement limiter of the barrel, and the shutter-casing 8 continues its movement to the limiter of its rollback (Fig. .1, Fig. 3.). Having reached the extreme rear position, the shutter-casing 8 moves forward under the action of the return spring 9. At the same time, he pushes the next cartridge out of the magazine and sends it into the chamber. Shutter-casing 8, comes to the breech breech. The combat grooves 12, made on the inner surface of the shutter-casing 8, become above the corresponding lugs 11 of the tide 1 of the axis of the return spring (Fig. 3). Further, the movable system of the shutter-casing 8, barrel 7, lug 1 with the axis of the return spring returns, under the action of the return spring 9, to the extreme forward position relative to the frame 4 of the gun until the lug 1 stops against the travel limiter. In this case, the oblique groove 2 of the tide interacts with the guide pin 3 of the pistol frame and the tide 1, located in the cutout 14 of the barrel, moves up transversely. The lugs 11 of the tide 1 of the axis of the return spring engage with the corresponding combat grooves 12 of the shutter-casing. The bore is locked (Fig. 2, Fig. 4.).
