Abstract

Electromechanical lock has housing, the inner and the outer with respect to the object being locked handles, and a placed in the housing mechanism for blocking-unblocking the outer handle and the cross piece. The blocking-unblocking outer handle and the cross piece mechanism has two plugs, those are fixed in the housing and the cover inside which there is installed a blocking plug with slots arranged in uniform way at the outer surface. At the outer surface of two plugs in movable way two discs are installed, those are rigidly connected to each other with stands, on one of those a blocking lever is installed. One arm of the blocking lever is arranged with a support boss, with possibility of coupling with one of slots of the blocking bushing, and the other arm can interact with the spring-supported wheel. The wheel is arranged with toothed sectors and bosses for possibility of contact with blocking lever, and with pins placed at the side surface of the wheel for possibility to interact with the spring. On the cross piece an axle is rigidly fixed, there a spring-supported lever is installed, with a locking pin fixed on it. One of the discs is arranged with a support boss, this can contact with the restricting element. The inner handle is installed on an onlay mounted on the door and is attached to it with possibility of motion by a flange. On the flange a pin is placed, this is placed eccentrically with respect to the axis of rotation of the inner handle and goes to the slot of one of the discs. The outer handle is installed on an onlay mounted on the door and is fixed on it with possibility of motion by means of a flange. The flange has a square opening with center at the axis of rotation of the outer handle with a square rod installed to it with one end, the other end goes to the square opening of the blocking plug and is fixed with support washers. Technical result: construction of the lock provides removal of force applied through the blocking-unblocking mechanism, by outer handle, at closed lock. This is achieved due to the fact that at closed lock the outer handle is not blocked with the cross piece and the inner handle and can rotate in free way, at operation of the driver blocking is performed through connection of the cross piece through the blocking-unblocking mechanism to the outer handle.
