AUTOMATIC WEAPONS LOCKING MECHANISM Russian patent published in 2019 - IPC F41A3/40 

FIELD: small arms.

SUBSTANCE: invention relates to small arms, namely to the design of semi-free valves with swinging locking elements mounted on the gate. Locking mechanism of the automatic weapon contains a bolt, made in the form of successively installed larva 1 and core 2, having the ability to rotate and interact with inclined surface 3 of larva 1 and stop 4 of receiver 5. At the end of core 2, interacting with inclined surface 3 of larvae 1, rollers 7 can be installed, and at the end, interacting with stop 4, rollers 8. Rollers 9 can be installed on larva 1. Stop 4 of the receiver can be made in the form of a removable liner, and working surface thereof in the profile can be represented as a straight line, broken line or a convex arc. Inclined surface of gate larva 1, interacting with end of core 2, in the profile can be represented as a straight line, a broken line or a concave arc.

EFFECT: constructive implementation of the shutter in the form of sequentially installed larva 1 and core 2, having the ability to rotate and interact with inclined surface 3 of larvae 1 and stop 4 of receiver 5, allows you to significantly simplify the locking mechanism.
