The clutch principle of this lock core clutch structure: during locking, lock core marble makes locking side column radially outward move along lock core, the inclined-plane of locking side column forces sliding shoe to do axially outwards motion, sliding shoe promotes lock pin again and outwards moves, make the contact surface of sliding shoe 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, lock core marble makes radially inwardly motion of locking side column, under the effect of lock pin back-moving spring, lock pin and sliding shoe be axially inwardly motion together, the contact surface of sliding shoe 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.

Lock core clutch structure of the present invention 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.If the corresponding breach of opening with the lock pin chute can match lock pin with this breach on the lock body afterbody is used for the step of lock core stop bit, just constituted the tapered end that lock core can dally.

The present invention is owing to adopt former and later two lock cores, and when utilizing in the axial direction the motion of sliding shoe and lock pin, both contact surfaces are in diverse location, thereby can 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.External force can't be unblanked and a destructive difficult problem of unblanking thereby solved brute force completely by acting on lock body or rear lock core before the lock core, further improved the theftproof performance of lock.

Further specify technical solution of the present invention below in conjunction with accompanying drawing.
