A rotating ring forced reset device for an anti-theft lock

Abstract

The invention provides a device for forcedly resetting a rotation ring of a burglar-proof lock and relates to the field of burglar-proof locks. The device is mainly characterized in that a resetting pillar is additionally arranged on an outer rotation ring of the lock; a third flange and a resetting pillar channel are additionally arranged in corresponding positions on a driven ring of a cam; when the rotation ring is incapable of automatically resetting, a lever handle is reversely rotated and the resetting pillar and a locking pillar are successively pushed to operate by using a resetting and pushing flange on the original driven ring and the locking pillar on the outer rotation ring, so that the forced resetting process of the rotation ring is completed. The device is capable of ensuring that a key can be inserted into the lock or withdrawn from the lock in any case; the device is free of space occupation and free of influence on overall layout; meanwhile, the contact between the additionally-arranged parts and the contact between the additionally-arranged parts and the original parts can be avoided in the daily operation process of automatic resetting of the rotation ring, so that the phenomenon of abrasion can be avoided.
