If a lock using the chute structure of the lock core of the utility model is unlocked through a non-matched key, after the key is inserted into the lock core, only the front lock core is driven to idling, the rear lock core which is fixed with a tappet rod is not capable of rotating, thereby achieving that the lock is unlocked through being pried by violent tools is effectively prevented.

Description

Clutch structure that a kind of lock core can dally and tapered end thereof

Technical field

The utility model belongs to mechanical lock, relates to clutch structure and tapered end thereof that a kind of lock cylinder and blade lock core can dally.

Background technology

The cylinder lock of existing side column structure locking and blade lock, under locking states, its lock core can not rotate relative to lock body.The outstanding problem that the lock core of this structure exists is: can not prevent effectively that violent tool sled twistlock core from unblanking.If the unlocking tool that working strength is enough big reverses lock core by force, can with on the door fixedly the bolt of tapered end twist off.

The utility model content

The purpose of this utility model is at above-mentioned situation, and the clutch structure and the tapered end thereof that provide a kind of lock core to dally adopt the lock core of this clutch structure can realize idle running, realize that effectively preventing to prize the twistlock core unblanks.

The utility model purpose is achieved in that the clutch structure that lock core can dally comprises the lock core that lock body is interior, and lock core and rear lock core before lock core is divided into are provided with the locking side column that can match with the lock core marble groove in the locking side column groove on the preceding lock core; The corresponding lock pin chute that is provided with on rear lock core with preceding lock core locking side column, 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; Be concavo-convex the cooperation between locking side column and the lock pin; Have at least one to adopt the inclined-plane to contact in lock pin or the locking side column groove with another.

Adopt the tapered end of the clutch structure that described lock core can dally, be to 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.

Lock core clutch structure of the present utility model can adapt to all cylinder lock and blade spring locks of adopting locking side column locking lock core, because the common feature of locking side column is to do radial motion along lock core, and their radial motion all be by with pellet shot from a slingshot or blade marble on the groove incompatible realization that matches.

The utility model is owing to adopt former and later two lock cores, utilizes that lock pin cooperates with the concavo-convex of locking side column in the preceding lock core in the axial direction in the rear lock core, thereby realizes 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.

Further specify technical solutions of the utility model below in conjunction with accompanying drawing.

The specific embodiment

See Fig. 1, the clutch structure that lock core can dally, lock core 1 and rear lock core 12 are provided with locking side column 6 in the locking side column groove 5 on the preceding lock core 1 before comprising, be pressed with spring 3 on the locking side column 6, be provided with the locking side column 6 that can match in the locking side column groove 5 on the preceding lock core 1 with lock core marble 4 grooves; On rear lock core 12 with preceding lock core 1 in the locking side column 6 corresponding lock pin chutes 11 that are provided with, 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; Be concavo-convex the cooperation between locking side column 6 and the lock pin 7; Lock pin 7 adopts inclined-plane 13 (referring to Fig. 2) to contact with locking side column groove 5.

Fig. 1 is the application of the utility model lock core clutch structure on the cylinder lock of existing deckle post with lock to tapered end shown in Figure 3, and the concrete structure of this lock can be referring to the ZL99115581.5 patent documentation.During application, be provided with step 14 at lock body 2 afterbodys of tapered end with rear lock core 12 stop bits, on the step 14 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 15 of restriction rear lock core 12 rotational angles on this step 14, the afterbody of rear lock core 12 is provided with the projection 16 that matches with lock body 2 afterbody upper limit breach 15.

Clutch principle of the present utility model: when unblanking, see Fig. 1, key is arranged lock core marble 4 in order and is made radially inwardly motion of locking side column 6, under the effect of lock pin back-moving spring 8, realize concavo-convex the cooperation between lock pin 7 and the locking side column 6, lock pin 7 stretches in the locking side column groove 5, and at this moment front and back lock core 1,12 fuses by lock pin 7, and preceding lock core 1 relative rear lock core 12 can not dally; During locking, earlier lock core is rotated an angle, see Fig. 5, because lock pin 7 adopts inclined-plane 13 to contact with locking side column groove 5, locking side column groove 5 forces in the lock pin 7 withdrawal rear lock cores 12, extract key again out, see Fig. 4, the periphery of lock core 1 before lock core marble 4 lack of alignment force locking side column 6 radially outward to withstand on, at this moment becoming end face between locking side column 6 and the lock pin 7 contacts, the interface of two lock cores 1,12 before and after this end face just is in, preceding lock core 1 relative rear lock core 12 can relatively rotate, and realizes idle running.

Fig. 6 is the application that the utility model lock core clutch structure is locked at the blade of existing deckle post with lock to tapered end shown in Figure 8, and the concrete structure of this lock can be referring to the ZL99233345.8 patent documentation.The clutch structure of the idle-run lock pin of this tapered end and operating principle and tapered end shown in Figure 1 are identical.Slightly different is that what the blade lock adopted is that blade marble 17 cooperates with locking side column 6.Lock among Fig. 7 is in blocking, and blade marble 17 is in the position that does not match with locking side column 6, and preceding lock core 1 relative rear lock core 12 cannot relatively rotate, and can not realize idle running; After inserting key 18, blade marble 17 is in the position of matching with locking side column 6; As shown in Figure 4, at this moment preceding lock core 1 relative rear lock core 12 can relatively rotate, and realizes idle running.

Same cylinder lock and the blade lock that adapts to similar following structure of the utility model:
