FIELD: construction. ^ SUBSTANCE: electromagnetic lock is related to the field of security engineering, in particular to locking devices controlled with facilities of electronic equipment. Lock may be used for locking of doors in premises, cabinets, safes. Mortise lock is intended for installation inside door jambs and is in open condition as voltage is supplied to electromagnet. Rim lock is intended for installation on door jambs. Electromagnetic lock comprises body, electromagnet, stem of crossbar with head, cylindrical spring, permanent cylindrical magnet and fixator in the form of cylindrical sleeve. Holes are arranged on side surface of fixator. Balls are located in openings. ^ EFFECT: invention provides for increased reliability of lock operation, reduced material intensity and lower energy consumption due to application of magnetic flux of permanent magnet. ^ 4 cl, 8 dwg |
