Lock core fixed motor drive clutch intelligent anti-theft lock for safe

Abstract

The invention provides a lock cylinder fixed type motor driven separation and reunion intelligent anti-theft lock used for safes, and relates to the field of anti-theft locks. The lock cylinder fixedtype motor driven separation and reunion intelligent anti-theft lock mainly aims at solving the problem that the related patented technology with a lock cylinder fixed type cross mechanical anti-theftlock as the core cannot be directly used together with the large safes in a matched manner. According to the scheme, a cam mechanism in the core technology mentioned above is omitted and is replacedwith a lock block capable of reciprocating, the special structure of the lock block has the control effect, the same as that for the cam mechanism, for a lock cylinder set, a clamp set mechanism comprising a clutch is further arranged on the lock block and is movably assembled together with a lock bolt drive and transmission mechanism, separation or reunion of the clamp set mechanism is achieved through driving of a motor drive device in a lock body, and therefore the performance characteristic that door leaf opening can be achieved through key unlocking, intelligent recognition unlocking andthe like is achieved; and the existing core technology is not changed, defects existing in existing intelligent locks are overcome, the product safety performance is remarkably improved, the lockset structure is substantially simplified, cost is reduced, and performance is stable and reliable.

Description

technical field [0001] The invention relates to an anti-theft lock, in particular to a motor-driven clutch intelligent anti-theft lock with a lock core fixed for a safe. Background technique [0002] In order to overcome the various disadvantages of the existing mechanical anti-theft locks and fingerprint code locks in the market, a series of products have been developed using the patented core technology of "a fixed cross mechanical anti-theft lock with a lock cylinder" (ZL201410020215.X), including "a A digital code, a single key combination kit" (ZL201610067763.7), "a profiling device for a key matching machine" (ZL201610068057.4), "a lock core fixed cross mechanical anti-theft lock matching a fingerprint lock" (ZL201610990489 .0), "A Cam Mechanism for Fingerprint Locks" (ZL201611045195.7), "Double Plug Anti-theft Door and External Locking Device" (ZL201610129609.8), "A Forced Reset Device for Rotating Rings of Anti-theft Locks" (ZL201710390280.5), "Fingerprint Lock Cam ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned deficiency that the relevant patented technology centered on "a cross mechanical anti-theft lock with a fixed lock cylinder" cannot be used directly with large safes, the present invention provides a lock cylinder fixed motor-driven clutch intelligent anti-theft lock for safes. The lock uses the overload protection device of the wheel handle of the original safe and other lock bolt drive transmission devices to cancel the cam mechanism in the above core technology and replace it with a reciprocating locking block. The special structure of the locking block It can have the same control function as the cam mechanism on the lock cylinder group, that is, if the key is correct, the locking block can move forward in the full range; if the key is incorrect or there is no key, the locking block cannot move in the full range; Automatic reset, complete forced reset by reverse movement of locking block
