Description

A kind of lock with idle rotation lock master structure
Technical field
The invention belongs to mechanical lock, relate to a kind of lock with idle rotation lock master structure.
Background technology
Aspect lockset, cylinder lock is the most widely used product always.In the existing cylinder lock, have and a kind ofly lock employing the match locking side column structure of incompatible control lock core open and close of locking side column, the molecular side pellet shot from a slingshot of submissile and notched angle marble is set on lock core, solved the weakness of not anti-skilled unlocking of traditional mechanical cylinder lock and sled twistlock core preferably, its structure can be referring to the ZL200610128732.4 patent documentation.But this lock still exists and is difficult to resist the problem that destructive brute force is unblanked.If the unlocking tool that working strength is enough big reverses lock core by force, the fixing bolt of tapered end can be twisted off.
Summary of the invention
The objective of the invention is at above-mentioned situation, a kind of lock with idle rotation lock master structure is provided, the lock core of this lock can dally, and realizes effectively preventing that violent tool sled twistlock core from unblanking and reduce the mutual opening rate of lock.
The present invention seeks to realize like this: lock with idle rotation lock master structure, comprise the lock core in the lock body, lock core and rear lock core before lock core is divided into, be arranged with the locking side column groove in the preceding lock core, and be arranged with two row notched angle marble, match with angle marble by locking side column, the molecular side pellet shot from a slingshot of submissile, locking side column is located in the locking side column groove, the outside of locking side column also is provided with sliding shoe in two locking side column grooves, sliding shoe is provided with projection or groove, locking side column is provided with the groove or the projection that can match with projection on the sliding shoe or groove, be provided with the locking side column back-moving spring between locking side column and the sliding shoe, between the end wall of sliding shoe and locking side column groove, be provided with the sliding shoe back-moving spring; It is corresponding with the locking side column groove of preceding lock core that the lock pin chute axially is set on rear lock core, and the lock pin chute has an end wall at the afterbody of rear lock core, places lock pin in the lock pin chute, and the lock pin back-moving spring is set between end wall in the lock pin chute and the lock pin; The elasticity of lock pin back-moving spring is greater than the elasticity of sliding shoe back-moving spring; Have at least one to adopt the inclined-plane to contact in lock pin or the locking side column groove with another; Be provided with the step that is used for the rear lock core stop bit at the lock body afterbody, on this step with the corresponding breach that has of the lock pin chute on the rear lock core, lock pin can match with this breach, also be provided with the spacing breach of restriction rear lock core rotational angle on this step, the afterbody of rear lock core is provided with the projection that matches with lock body afterbody upper limit breach.
The present invention's lock is owing to adopt former and later two lock cores, and the side pellet shot from a slingshot of being made up of locking side column, submissile that matches with notched angle marble and the sliding shoe corresponding with locking side column be set in preceding lock core, utilize the motion of lock pin between front and back lock core in the rear lock core, thereby realize the clutch between two lock cores.Adopt the lock of lock core clutch structure of the present invention,, can only drive preceding Lock cylinder idling behind the insertion lock core, the rear lock core that is fixed with sword iron is rotated if use non-matching key to unblank.Make external force act on lock body or rear lock core, thereby solved powerful unblanking and a destructive difficult problem of unblanking completely, further improved the theftproof performance of lock by preceding lock core.Owing to adopt two row's angle marbles, can reduce the mutual opening rate of lock.
Further specify technical solution of the present invention below in conjunction with accompanying drawing.

The specific embodiment
See Fig. 1 to Fig. 4, lock with idle rotation lock master structure, comprise lock body 2, lock core in the lock body 2, lock core 1 and rear lock core 12 before lock core is divided into, be arranged with the notched angle marble 15 of two rows in the preceding lock core 1, match with angle marble 15 by locking side column 4, the side pellet shot from a slingshot that submissile 21 is formed, in two locking side column grooves, also be provided with the sliding shoe 6 corresponding with locking side column 4, be respectively equipped with the projection 14 (groove) and the groove 13 (projection) that can cooperate on sliding shoe 6 and the locking side column 4, be provided with locking side column back-moving spring 5 between locking side column 4 and the sliding shoe 6, between the end wall of sliding shoe 6 and locking side column groove, be provided with sliding shoe back-moving spring 3; On rear lock core 12 with the corresponding lock pin chute 11 that is provided with of locking side column groove in the preceding lock core 1, lock pin chute 11 has an end wall 10 at the afterbody of rear lock core, place lock pin 7 in the lock pin chute 11, between end wall 10 in lock pin chute 11 and the lock pin 7 lock pin back-moving spring 8 is set; The elasticity of lock pin back-moving spring 8 is greater than sliding shoe back-moving spring 3; Lock pin 7 adopts inclined-plane 16 (referring to Fig. 3) to contact with the locking side column groove; Be provided with step 17 at lock body 2 afterbodys with rear lock core 12 stop bits, on the step 17 with the lock pin chute 11 corresponding breach 9 of opening, lock pin 7 in the lock pin chute 11 can match with this breach 9, also be provided with the spacing breach 18 of restriction rear lock core 12 rotational angles on this step 17, the afterbody of rear lock core 12 is provided with the projection 19 that matches with lock body 2 afterbody upper limit breach 18.
Clutch principle of the present invention: when unblanking, see Fig. 1, inserting key 20 arranges two row's angle marbles 15 in order, locking side column back-moving spring 5 makes the radially inwardly motion of submissile 21 and two locking side column 4, sliding shoe 6 separates with groove 13 (projection) with projection 14 (groove) on the locking side column 4, locking side column groove before the preceding lock core 1 of rotation aligns two lock pins 7 in the rear lock core 12 respectively in the lock core 1, because the elasticity of lock pin back-moving spring 8 is greater than sliding shoe back-moving spring 3, two lock pins 7 simultaneously with the sliding shoe in the locking side column groove 6 in sinciput is gone forward side by side the locking side column groove, at this moment front and back lock core 1,12 fuse by two lock pins 7, and preceding lock core 1 relative rear lock core 12 can not dally; During locking, earlier preceding lock core 1 is rotated an angle, see Fig. 7, because lock pin 7 all adopts inclined-plane 16 to contact (referring to Fig. 3) with the locking side column groove, the locking side column groove forces in the lock pin 7 withdrawal rear lock cores 12, sliding shoe 6 resets, extract key 20 again out, see Fig. 5, Fig. 6, each angle marble 15 lack of alignment forces submissile 21 and locking side column 4 radially outward to be moved, and projection 14 (groove) and groove 13 (projection) on sliding shoe 6 and the locking side column 4 are chimeric, locking side column 4 is with sliding shoe 6 location, at this moment between sliding shoe 6 and the lock pin 7 contact end face just be in before and after two lock cores 1,12 interface, preceding lock core 1 relative rear lock core 12 can relatively rotate, and realizes idle running.
