Abstract
The utility model discloses a structurally improved lock, which comprises a lock body, two points in the lock body are provided with racing lock cores with a same structure, the utility model is characterized in that: each lock core turn sheath top is fixed with a shifting block. The utility model novel tapered end compared to the current tapered end, as adopting the racing lock core, thus make the performance that prevent technological unlock and destructively lock picking largely improved.
Description
Technical field
The utility model belongs to mechanical lockset, is specifically related to a kind of lock head structure 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 improved lock head structure that comprises idle-run lock pin is provided.
The utility model purpose is achieved in that improved lock head structure 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 initiatively lock core, locking plate, the locking plate spring and the driving lever of unblanking, initiatively have the locking plate groove on the cross section of lock core, in the locking plate groove locking plate is installed, the locking plate spring, also comprise turning set, turning set is set in the lock body, initiatively lock core is installed in the turning set, the driving lever of unblanking is installed in the turning set afterbody, groove the inside at the active lock core is equipped with the idle running bar, the groove fit of idle running bar bottom and locking plate top end face, dead slot the inside at turning set is equipped with rotation strip, the top of idle running bar is rotated the bar bottom and pushes down, the idle running bar is stuck between turning set and the active lock core, and the rotation strip top is pushed down by parallel pearl, parallel pearl, parallel pearl spring is installed in the hole of bead of lock body.
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 improved lock head structure of the utility model 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.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
The improved lock head structure of the utility model is seen Fig. 1, Fig. 2, one lock body 1 is arranged, two in the lock body 1 is provided with the idle-run lock pin of same structure, the end of each lock core turning set 3 all is fixed with shifting block 2, described idle-run lock pin comprises initiatively lock core 11, locking plate 9 and locking plate spring 12, initiatively have the locking plate groove on the cross section of lock core 11, locking plate 9 is installed in the locking plate groove, locking plate spring 12, also comprise turning set 3, turning set 3 is set in the lock body 1, initiatively lock core 11 is installed in the turning set 3, groove the inside at active lock core 11 is equipped with idle running bar 8, idle running bar 8 bottoms cooperate with the groove 13 of locking plate 9 top end faces, dead slot the inside at turning set 3 is equipped with rotation strip 7, and the top of idle running bar 8 is rotated bar 7 bottoms and pushes down, and idle running bar 8 is stuck between turning set 3 and the active lock core 11, rotation strip 7 tops are pushed down by parallel pearl 6, parallel pearl 6, parallel pearl spring 5 is installed in the hole of bead of lock body 1.As shown in Figure 2, key 10 inserts in the lockhole, locking plate 9 overcomes 12 effects of locking plate spring and is moved, make idle running bar 8 enter groove 13 on the locking plate 9, rotation strip 7 moves down under parallel pearl 6 and 5 effects of parallel pearl spring, rotation strip 7 is stuck between turning set 3 and the active lock core 11, rotation strip 7 breaks away from lock body 1, initiatively lock core 11 drive turning sets 3 can rotate and realize unblanking, otherwise turning set 3 engages with lock body 1 by rotation strip 7, initiatively lock core 11 can arbitrarily rotate, and square opening 4 is arranged on the lock body 1, makes things convenient for shifting block 2 to rotate.
