Description
Technical field
The utility model belongs to mechanical lock, relates to a kind of tapered end and key with adopting vane spring idle rotation lock master structure.
Background technology
Chinese patent ZL200710035717.X document discloses the tapered end that a kind of lock core can dally.This tapered end comprises the lock core in lock body, the lock body, lock core and rear lock core before lock core is divided into, be provided with the locking side column and the sliding shoe that can match in the locking side column groove on the preceding lock core with v-depression on the lock core marble, 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.Because the preceding lock core of this tapered end can dally, external force can't act on lock body or rear lock core by preceding lock core, and the reasonable brute force that solved is unblanked and a destructive difficult problem of unblanking.Unblank very effective to preventing violent tool sled twistlock core.But find that in manufacture process also there are some problems in this tapered end: mainly be that structure is complicated, component are more, and processing time consuming, machining accuracy are difficult to guarantee that cost is higher.
In the existing lock, also has a kind of key that adopts the two sides all to be milled with identical tartar, the thickness of this key is bigger, so the lockhole on the tapered end is corresponding bigger, and this just can utilize the instrument that size is thicker and strength ratio is higher to insert the chance that the realization violence is unblanked in the lockhole for the lawless person provides.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure simpler, tapered end with adopting vane spring idle rotation lock master structure and key that safety is higher.
Tapered end of the present utility model, comprise the preceding lock core in the lock body, preceding lock core upper edge axis is provided with some blade marbles, be provided with the locking side column that can match in the locking side column groove on the preceding lock core with v-depression on the blade marble, locking side column is provided with step-like groove, the top of locking side column groove is provided with and locking side column card and the fixed part that the scalariform groove matches of appearing on the stage, between fixed part and locking side column, be provided with radially back-moving spring of locking side column, between the end wall of locking side column and locking side column groove, be provided with the axial back-moving spring of locking side column, a side of described blade marble be provided with can with the protuberance that matches with the boss of tartar on the key.
Described fixed part both can be a lock core upper stop piece before being embedded in, and also can be the sleeve on the lock core before being enclosed within.
With the supporting key of the utility model tapered end, comprise a spoon sheet, on a face of spoon sheet, be provided with boss, two sidewalls of boss are provided with tartar.
The relative prior art of the utility model, cancelled sliding shoe, only kept locking side column, by matching with card on the preceding lock core in that step-like groove is set on the locking side column, reaching the control locking side column is unblanking or axially-movable during blocking, realize the clutch of front and back lock core, lock core can dally before making.This structure makes lock head structure simpler, and component reduce, and easier processing can further reduce cost.Again because the key that adopted has only one side to be provided with boss, and its thickness can reduce, make corresponding the reducing of lockhole of tapered end, can prevent to utilize size is thicker and strength ratio is higher instrument to insert the lockhole violence and unblank, the safety of lock is improved.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
