An electromagnetic anti-theft door

Abstract

The invention relates to the technical field of anti-theft doors, and discloses an electromagnetic anti-theft door, which includes a door frame, a door leaf and an anti-theft lock on the door leaf. The anti-theft lock includes a lock body and a key. The lock body includes at least one bolt and a lock fixed in the lock body. The expansion and contraction of the lock bolt is controlled by the energization or de-energization of the first electromagnet, and the energization or de-energization of the first electromagnet is controlled by the first control circuit. There is a slot recessed on the side of the lock cylinder facing the outside of the door. , a control module that can connect or disconnect the control circuit is arranged in the lock cylinder, and the control module includes N (N≥8) through slots that are recessed in the inner wall of the slot along its circumferential direction and / or axial direction. A contact module fixedly arranged at one end of the through slot away from the slot and a telescopic member elastically and telescopically arranged in each through slot, the key includes an insertion rod and a first control circuit that can be telescopically arranged on the outer ring wall of the insertion rod Connected unlocking parts, thieves can't open the security door at all by using the traditional crochet and tin foil filling unlocking methods.

Description

technical field [0001] The invention relates to the technical field of anti-theft doors, in particular to an electromagnetic anti-theft door. Background technique [0002] The anti-theft essence of the anti-theft door lies in the anti-theft lock set on it. The anti-theft locks are generally divided into A-level, B-level and C-level. It takes more than 5 minutes to open the C-level lock technology, and the C-level lock takes a long time to open, which takes several hours. Generally, thieves will give up directly when encountering the C-level lock. The essence of the C-level lock is the probability of opening. The marble structure on it is double-row 48 blades and double-type side column locking, but the manufacture of this kind of lock requires extremely high precision, and the production cost is extremely high. Therefore, the cost is also high. Based on cost considerations, people mainly use A-level locks. locks and Class B locks. [0003] The unlocking skills used by thie...
