locking devices. SUBSTANCE: electromechanical lock has rotary bushing with locking cam installed in body. Shaft carrying electromagnet with armature is put into hole of bushing. Armature so interacts with walls of groove of rotary bushing that in case of simultaneous supply of voltage to electromagnet and rotation of shaft armature rests against wall of groove of bushing transmitting rotation from shaft to it and if there is no voltage across electromagnet armature is pushed from groove under action of its own weight with rotation of shaft and rotation from shaft is not transmitted to bushing. EFFECT: given design of lock provides for its long-term operation from autonomous miniature power supply cells. 8 cl, 5 dwg |
