FIELD: construction.

SUBSTANCE: electromechanical lock comprises a cylindrical body made of magnetically conductive material, on the inner rear part of which there is a bore, where a lock ring is installed, an electromagnetic coil, the diameter of the cheeks in which is equal to the inner diameter of the body, installed in the body so that one cheek touches the lock ring, a cylindrical stem made of non-magnetic material, on one end of which a bushing is placed and fixed, made of magnetically conductive material, on the outer side of which there is a cylindrical permanent magnet fixed by forces of magnetic attraction, a return cylindrical spring. It additionally includes a fixator and a locking mechanism, m made in the form of rectangular plates, a fixator twisting spring, a locking mechanism twisting spring, a base, a cover, an axial bushing of the fixator, a limiting bushing of the fixator, a support bushing of the locking mechanism, a limiting bushing of the locking mechanism, a cross bar in the form of a cross bar bushing, installed on the axis without the possibility of longitudinal displacement fixed on the plate. The bushing comprises two sections with different outer diameters, a smaller one adjacent to the plate and a larger one - the outer one.

EFFECT: possibility to lock preferably plastic doors, elimination of the possibility of unauthorised access and possibility of access in case of power loss.
