Description

The clutch structure of pellet shot from a slingshot (blade) lock idle-run lock pin

Technical field

The utility model belongs to mechanical lock, relates to the clutch structure of a kind of pellet shot from a slingshot (blade) lock idle-run lock pin.

Background technology

At present, a kind of clutch structure (seeing Chinese patent application No. 200710034226.3) that is used for the idle-run lock pin of cylinder lock and blade lock is arranged.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.But owing to all adopt the inclined-plane contact between sliding shoe and the locking side column in this structure,, make the component motion not too flexible, influence the result of use of locking so friction is bigger.

The utility model content

The purpose of this utility model is at above-mentioned situation, and the clutch structure of a kind of pellet shot from a slingshot (blade) lock idle-run lock pin is provided.This architecture advances the way of contact between sliding shoe and the locking side column, reduced friction, improved the result of use of lock.

The utility model purpose is achieved in that the clutch structure of pellet shot from a slingshot (blade) lock idle-run lock pin comprises the lock core in lock body, the lock body, lock core and rear lock core before lock core is divided into, on preceding lock core, be provided with and go up the locking side column that V-shaped groove matches with lock core marble (blade), on preceding lock core, be provided with the slide block chute that communicates with the locking side column groove, in the slide block chute, be provided with slide block, radially be provided with the identical locking side column of the polarity magnetic patch group that resets at slide block and locking side column upper edge lock core, and both adopt inclined-plane to contact with another along lock core shaft to one of them; On rear lock core,, 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 with the corresponding lock pin chute that is provided with of preceding lock core top shoe chute.

In the described technical scheme, make progress along lock core shaft between slide block and the locking side column, wherein locking side column adopts the inclined-plane to contact with slide block, and perhaps slide block adopts the inclined-plane to contact with locking side column.

The clutch principle of the utility model clutch structure: during locking, lock core marble (blade) makes locking side column radially outward move along lock core, locking side column forces slide block outwards motion vertically, 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, under the repulsive force effect of magnetic patch group, 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, in the lock core, at this moment front and back lock core fused by lock pin before the contact surface of slide block and lock pin returned to, and the relative rear lock core of preceding lock core can not dally.

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.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 rear lock core stop bit, just constituted the tapered end that lock core can dally.

The utility model is owing to radially be provided with the locking side column magnetic patch group that resets between slide block and locking side column, and contact with another on axial one of them employing inclined-plane, can reduce contact friction between the two, make the component motion more flexible, improve the result of use of lock.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.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 solutions of the utility model below in conjunction with accompanying drawing.
