Description

A kind of idle-run lock head
Technical field
The utility model belongs to mechanical lock, relates to the tapered end that a kind of lock core can dally.
Background technology
At present, the lock core clutch structure (seeing Chinese patent application No. 200710034226.3) that has a kind of tapered end to adopt lock core to dally.Relative rear lock core of lock core and lock body were done the idle running of 360 degree before tapered end adopted when can be implemented in locking after this lock core clutch structure, thereby reached effectively anti-skilled unlocking and sled twistlock core.This being locked in reaches still existence limitation on the range of application on the structure, be further improved.
The utility model content
The purpose of this utility model is at above-mentioned situation, and a kind of idle-run lock head is provided.This tapered end combines the characteristics of prior art, and its structure is more reasonable, and range of application is wider.
The utility model purpose is achieved in that idle-run lock head comprises the lock core in lock body, the lock body, lock core and rear lock core before lock core is divided into, be provided with the locking side column that two rows are with the lock core marble of V-shaped grooves and match with V-shaped groove on each row's lock core marble respectively on the preceding lock core, on preceding lock core, be respectively equipped with the slide block chute that communicates with two locking side column grooves, in the slide block chute, be provided with slide block, between slide block and the locking side column along lock core shaft to having at least one to adopt the inclined-plane to contact with another; On rear lock core with the corresponding lock pin chute that is provided with of preceding lock core top shoe chute, place lock pin in the lock pin chute, the lock pin back-moving spring is set between end wall in the lock pin chute and the lock pin, be provided with the step that is used for the rear lock core stop bit at the lock body afterbody, the corresponding breach that has with the lock pin chute on this step, lock pin can match with this breach.
In the described technical scheme, the way of contact that makes progress along lock core shaft between slide block and the locking side column comprises: locking side column adopts the inclined-plane contact with slide block, and perhaps slide block employing inclined-plane contacts with locking side column, and perhaps both all adopt the inclined-plane to contact.
In the technique scheme, can also be radially to be provided with the locking side column back-moving spring along lock core between slide block and the locking side column, the elasticity during with increase locking side column return.
The clutch principle of this idle-run lock head: during locking, lock core marble (blade) makes locking side column radially outward move along lock core, locking side column force slide block along lock core shaft to outwards moving, and lock pin pushed up back in the rear lock core, make the contact surface of slide block and lock pin just be in before and after the interface of two lock cores, the preceding relative rear lock core of lock core can relatively rotate, and realizes idle running; When inserting key unlocking, locking side column matches with V-shaped groove on the lock core marble (blade) and radially inwardly moves along lock core, under the effect of lock pin back-moving spring, lock pin and slide block be inwardly motion vertically together, the contact surface of slide block and lock pin returns in the preceding lock core, at this moment front and back lock core fuses by lock pin, and the relative rear lock core of preceding lock core can not dally.
The utility model combines the characteristics of prior art, and it is combined with double cylinder lock, and its structure is more reasonable, has enlarged range of application.This idle-run lock head, if using non-matching key unblanks, can only drive preceding Lock cylinder idling after inserting lock core, the rear lock core that is fixed with sword iron is rotated, make external force act on lock body or rear lock core by preceding lock core, thereby solved powerful unblanking and a destructive difficult problem of unblanking completely, further improved the theftproof performance of lock, adopted double pellet shot from a slingshot can reduce mutual opening rate.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Fig. 4, Fig. 5 be locking side column with slide block between adopt different inclined-plane contact schematic diagrames.
Fig. 6, Fig. 7 are respectively the different user mode schematic diagrames of Fig. 1, Fig. 2.
Fig. 8 is an another kind of structural representation of the present utility model.
The specific embodiment
See Fig. 1 to Fig. 3, idle-run lock head comprises the lock core in lock body 2, the lock body 2, lock core 1 and rear lock core 13 before lock core is divided into, be provided with the locking side column 4 that two rows are with the lock core marble 7 of V-shaped grooves 16 and match with V-shaped groove 16 on each row's lock core marble 7 respectively on the preceding lock core 1, on preceding lock core 1, be respectively equipped with the slide block chute 6 that communicates with two locking side column grooves 14, be provided with slide block 3 in slide block chute 6, locking side column 4 contacts with slide block 3 to employing inclined-plane 41 along lock core shaft; On rear lock core 13 with the preceding lock core 1 top shoe chute 6 corresponding lock pin chutes 12 that are provided with, place lock pin 9 in the lock pin chute 12, between end wall in lock pin chute 12 and the lock pin 9 lock pin back-moving spring 11 is set, be provided with the step 10 that is used for the rear lock core stop bit at lock body 2 afterbodys, the corresponding breach 101 that has with the lock pin chute on this step 10, lock pin 9 can match with this breach 101.
As Fig. 4, shown in Figure 5, also can be that slide block 3 adopts inclined-plane 31 to contact with locking side column 4, perhaps slide block 3 all adopts inclined- plane 31,41 to contact with locking side column 4.
State when unblanking is seen Fig. 1, Fig. 2, lock core 1 before key 15 inserts, the V-shaped groove of respectively arranging on the lock core marble 7 16 before making in the lock core 1 aligns, under the effect of lock pin back-moving spring 11, lock pin 9 and slide block 3 along lock core shaft to inwardly moving, and promote in locking side column 4 radially inwardly stretches into V-shaped groove 16 on the lock core marble 7 along lock core, position before the contact surface 8 of lock pin 9 and slide block 3 is in the lock core 1, and the end of lock pin 9 be in lock body afterbody step 10 on the position that is separated of breach 101, at this moment, preceding lock core 1 fuses by lock pin 9 and rear lock core 13, can rotate relative to lock body 2.
State during locking is seen Fig. 6, Fig. 7, V-shaped groove on the preceding lock core 1 internal cylinder pellet shot from a slingshot is out-of-line, locking side column is radially outward backed down by lock core marble, slide block that contacts with the locking side column inclined-plane and lock pin overcome the lock pin back-moving spring along lock core shaft to outwards moving, both contact surfaces 8 are in and front and back two lock cores 1, the position that 13 contact surfaces 17 overlap, and the end of lock pin is in the position of matching with breach on the lock body afterbody step, at this moment, preceding lock core 1 relative rear lock core 13 can dally, rear lock core fuses and can not rotate by lock pin and lock body, and lock can not be opened.
Another embodiment of the present utility model sees Fig. 8, and the difference of it and the foregoing description is radially to be provided with locking side column return spring 5 along lock core between slide block 3 and locking side column 4.
