UNAUTHORIZED ACCESS PROTECTION DEVICE Russian patent published in 2023 - IPC E05B47/00 

FIELD: unauthorized access protection devices.

SUBSTANCE: device of protection against unauthorized access belongs to locks of electromechanical type. The device comprises a housing (1), a crossbar (2), an electric motor (3) containing a stator with an excitation winding (4) and a rotor (5), the shaft (6) of which is connected to the crossbar (2) through a conversion device (7) made in the form of a gearbox. The field winding is electrically connected to the control board (9). The body (1) is made detachable. An electric motor (3) with a control board (9) is installed in one part of it, and a gearbox (7) is installed in the other part, the output shaft (10) of which passes through a through hole (11) in this part of the housing. The bolt (2) consists of two parts, one of which is made in the form of a rotary disk (12) mounted on the shaft (10) of the gearbox, and the other part of the bolt is made in the form of a separate part installed on the object to be locked (14). Hooks (13) are made on both sides of the disk (12). On the side surfaces of the body and a separate part, grooves (15) are made along the circumference, with the possibility of their simultaneous interaction with the hooks (13) of the disk (12).

EFFECT: increasing the level of noise immunity, vibration resistance and protection of protected objects from unauthorized access due to the use of a bayonet connection of two parts of the crossbar, a planetary gearbox and a brushless electric motor.
