ELECTROMECHANICAL LOCK Russian patent published in 2018 - IPC E05B47/02 

FIELD: locks; electrical equipment.

SUBSTANCE: electromechanical lock relates to the field of security equipment, in particular to the electronic equipment controlled locking devices. Electromechanical lock comprises base 1, latch 8, on which a hook is formed. On the axial lock bushing a torsion spring 17 is located, which moves the latch 8 into the lock open state. In the latch hole 14 a pin 19 is installed protruding beyond the latch 8 side surfaces. Locking mechanism 20 is made in the form of a U-shaped bracket. In the lock closed state, the locking mechanism 20 bracket inner part is the hook 11 with the pin 19 lower inner part, whose ends are in the locking mechanism 25 adjacent slots. Slots 25 front end face is made with a bevel in the base 6 front surface direction. Slots 26 front end face bevel angle size is so, that in the locking mechanism 21 position for the lock closed state, the slots front end surface hold the latch 8 from rotation by the pin 20, and in the locking mechanism 20 position for the lock open state it does not hold the latch 8 from rotation by the pin 19. In the lock open state, under coil spring 42 action the pusher 39 protrudes above the surface 6. Under the latch 17 torsion spring action, the latch 8 occupies position, by the latch 9 open part forming the input slot for the bolt 5 bushing. Under the locking mechanism 26 torsion spring action, the locking mechanism 20 occupies position, in which the latch 8 is not held by the pin 19 from turning. During the lock closing, the bolt 3 enters into the rectangular hole 7. Bolt 5 bushing turns the latch 8 and the latch 19 pin enters into the latch 20 slots 25 and turns it. During the latch 8 rotation and reaching the locking mechanism 20 bracket inner surface of the latch 27 end surface, the latter enters inside the locking mechanism 20 bracket, blocking the locking mechanism 20 reverse rotation possibility. Lock is closed. To open the lock to the electromagnets 33, 34 a voltage is applied. Latch 27 releases the locking mechanism 20, which rotates under the locking mechanism 26 torsion springs, the latch 17, and also the pusher 42 coil spring action. During the locking mechanism rotation, held in the slots 25 latch 8 pin 19 releases. Door slightly opens by the pusher 39 cylindrical spring 42 force. Lock is open.

EFFECT: electromechanical lock can be used for locking doors, to exclude the unauthorized access possibility.
