Description

The antitheft blade lock that a kind of lock core can dally
Technical field
The utility model belongs to mechanical lock, relates to the antitheft sylinder that a kind of lock core can dally.
Background technology
Aspect lockset, the blade lock is the most widely used product always.In the existing blade lock, have and a kind ofly lock employing two locking plates that are stacked as a group mutually of many groups are set on lock core, have V-shaped groove on the locking plate, control the open and close of lock core by locking plate and cooperating of locking side column.This structure has solved the weakness of not anti-skilled unlocking of traditional mechanical blade lock and sled twistlock core preferably, and its structure can be referring to the ZL200320115784.X 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 is prized the twistlock core by force, the fixing bolt of tapered end can be twisted off.
The utility model content
The purpose of this utility model is at above-mentioned situation, and the antitheft sylinder that provides a kind of lock core to dally, this lock can realize effectively preventing that violent tool sled twistlock core from unblanking, and reduce the mutual opening rate of lock.
The utility model purpose is achieved in that the antitheft sylinder that lock core can dally comprises lock body, the interior lock core of lock body, lock core and rear lock core before lock core is divided into; Be provided with some two in the preceding lock core and be stacked as one group locking plate and the locking side column that matches with V-shaped groove on the locking plate mutually, in the locking side column groove, also be provided with and the sliding shoe corresponding with locking side column, be respectively equipped with the projection (groove) and the groove (projection) that can cooperate on sliding shoe and the locking side column, 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; With the corresponding lock pin chute that is provided with of locking side column groove of preceding lock core, the lock pin chute has an end wall at the afterbody of rear lock core on 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 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 utility model lock is owing to adopt former and later two lock cores, and locking plate and the locking side column and the sliding shoe corresponding with locking side column of multi-group V-shaped groove 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 the utility model lock core clutch structure,, 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.Use two to be one group locking plate, more increased the tartar quantity of key, make security performance higher.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.

The specific embodiment
See Fig. 1 to Fig. 4, the antitheft blade lock that lock core can dally, 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, before be provided with in the lock core 1 five groups two be stacked as mutually one group locking plate 15 and with locking plate 15 on the locking side column 4 that matches of V-shaped groove and 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 utility model: when unblanking, see Fig. 1, inserting key 20 makes and respectively organizes locking plate 15 and arrange in order, make radially inwardly motion of locking side column 4 simultaneously, 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 the lock pin 7 in the rear lock core 12 in the lock core 1, because the elasticity of lock pin back-moving spring 8 is greater than sliding shoe back-moving spring 3, lock pin 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 lock pin 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 organizes locking plate 15 lack of alignment forces 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.
