Comparing with the prior plug, the plug of the utility model adopts the idle plug, thereby making the properties on preventing technical unlocking and destructive prying are further improved.

Description

A kind of lock head structure of built-in type mortise door lock

Technical field

The utility model belongs to mechanical lockset, is specifically related to a kind of tapered end of 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 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 lock head structure that comprises the built-in type mortise door lock of idle-run lock pin is provided.

The utility model purpose is achieved in that the lock head structure 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 comprises the cylindric lock core that is arranged at rotationally in the lock body, and places between the fitting face of lock body and lock core, is used to the pellet shot from a slingshot, the card key mechanism that stop lock body and lock core to rotate mutually; Cylindric lock core comprises initiatively lock core and the turning set that is sleeved on outside the active lock core, between active lock core and turning set, be provided with lining, the external surface of lock core some ring-shaped grooves with axis normal that be arranged in parallel initiatively, be symmetrical arranged a pair of arc slide and a slide stage clip in every ring-shaped groove, the two ends of slide stage clip are connected with the tail end of a pair of arc slide respectively, two front end opposite position keeps certain interval, and the symmetric position of the outer rim of every pair of arc slide is provided with a keyway respectively; Described pellet shot from a slingshot, card key mechanism comprise two bar shaped card keys and some to pellet shot from a slingshot, two bar shaped card keys and axis are set in parallel in the chute of turning set both sides, lock body inwall and chute relevant position are provided with card key groove, pellet shot from a slingshot is arranged at the card key groove of lock body, and the movable end of pellet shot from a slingshot is crimped on the card key.

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 lock head structure of the utility model built-in type mortise door lock 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.
