Abstract
The utility model discloses a plug, which comprises a lock body, two ends in the lock body are provided with idle plugs with the same structure. The utility model is characterized in that the end part of each plug rotating sleeve is fixed with a follower. Comparing with the prior plug, the plug in the utility model adopts the idle plug, thereby making the properties on preventing technical unlocking and destructive prying are further improved.
Description
Technical field
The utility model belongs to mechanical lockset, is specifically related to a kind of tapered end that is used for the built-in type mortise door lock.
Background technology
The tapered end of existing built-in type mortise door lock wherein has a kind of twin-lock cored structure, can be from two different directions with key respectively with lock-switch.Two lock cores all are to adopt identical structure, are provided with a shifting block between two lock core ends, and shifting block is realized and the interlock of dead bolt thereby each lock core can drive by an arrangement of clutch.The deficiency of this tapered end is that the lock core that is adopted is not high aspect safety, can not effectively prevent skilled unlocking and destructive picking lock.
Preventing skilled unlocking and destructive picking lock aspect of performance, the lock core that some theftproofs better can dally has appearred at present, this lock core is to be provided with a turning set between lock core and lock body, be characterized in, can unblank when unblanking with matched key, and when using non-matching key to unblank, can only make lock core relatively rotate cover idle running, this lock core can make external force can't act on lock body and sword iron, thereby has solved powerful unblanking and a destructive difficult problem of unblanking preferably.At present, this class lock core does not also have to find to be applied on the tapered end of built-in type mortise door lock.
Summary of the invention
The purpose of this utility model is at above-mentioned situation, and a kind of tapered end that is used for the built-in type mortise door lock that comprises idle-run lock pin is provided.
The utility model purpose is achieved in that the tapered end of built-in type mortise door lock comprises lock body, and the two in the lock body is provided with the idle-run lock pin of same structure, and the end of each lock core turning set is fixed with shifting block; Described idle-run lock pin is made up of internal cylinder and turning set, internal cylinder is enclosed within the turning set, in internal cylinder, be provided with the pellet shot from a slingshot and the internal key pilot trench of band hole groove, be provided with internal key in the internal key pilot trench, on described turning set, offer the external key draw-in groove, be provided with external key in the external key draw-in groove, the position relative with the external key draw-in groove at described lock body inwall is provided with draw-in groove.
Although the turning set on the idle-run lock pin engages with shifting block, but can only make lock core relatively rotate cover idle running when unblanking, can not unblank, have only the use matched key owing to the use non-matching key, turning set and lock core are rotated together, drive shifting block and rotate the switch of realizing lock.
The utility model tapered end is compared with existing tapered end owing to adopt idle-run lock pin, make its prevent skilled unlocking and and the performance of destructive picking lock be further enhanced.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
