FIELD: construction.

SUBSTANCE: lock mechanism is equipped with a key for its unlocking and comprises a body, a drum and a grip. The body and the drum are equipped with pins, located coaxially along the circumference along the axis to form the mechanism itself. The drum is installed into the body as capable of rotation around its axis. The grip is rigidly installed in the body. Cuts or ledges for a blocked part are made in the grip and the drum. Each pin comprises at least three parts. The last part of pins is made as composite - from a stepped shaft and a cylinder, which comprises the stepped shaft. Length of part of the stepped shaft entering the cylinder is less than the latter. The last part of pins is equipped with springs of different stiffness, or not all parts are spring-loaded. Coaxial holes are made in the body and the drum of the lock - in the body of larger length than in the drum. Additional pins are installed into holes of the body, interacting with the drum during vibration. Length of additional pins is equal to length of holes made in the body.

EFFECT: increased reliability of operation of a lock mechanism.
