Description

A kind of anti-prizing type lock

Technical field

The utility model relates to a kind of tapered end, particularly a kind of shell fragment tapered end of taking split type combined lock core.

Background technology

Traditional mechanical lock head product mainly is the whole lock core structure that adopts pellet shot from a slingshot or shell fragment, its structure generally comprises lock body, whole lock core, pellet shot from a slingshot or shell fragment, only thereby lock core could rotate in lock body and open lockset when all pellets shot from a slingshot or shell fragment are in ad-hoc location simultaneously, when pellet shot from a slingshot or shell fragment are not in this specific enable possition, one end of pellet shot from a slingshot or shell fragment blocks lock body one end and then blocks lock core and make lock core not rotate in lock body and open lockset, but the tapered end of this class formation exists not pick-proof, the not anti-technical disadvantages of dialling, in case the burglar utilizes instrument to stir the phenomenon that pellet shot from a slingshot or shell fragment will occur misplacing, thereby makes tapered end be unlocked; And the pick-proof performance is just more unreliable, because being used to now to insert the lock core hole of key on the tapered end all be polygon, when stealer is used with the similar instrument insertion lock core hole of key, will block lock core hole easily, as long as clamp twisting with instruments such as spanner, hawkbills, following three kinds of phenomenons will appear; One, pellet shot from a slingshot or shell fragment dislocation occurs and make lock core be twisted; Two, the tapered end fixed screw is not resisted torque forces and is twisted off; Three, fixedly the base plate of tapered end does not have weldering dead or fixing when bad, and the then whole tapered end base plate of will ining succession is reversed together.Above that a kind of phenomenon no matter occurs, lockset all can be opened easily by the burglar, and lockset can't play effective antitheft effect.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of pick-proof, anti-a kind of anti-prizing type lock of dialling function admirable to be provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-prizing type lock, comprise lock body, lock core, and lock core is arranged in the lock body and can rotates relative to lock body; Wherein: lock core leading portion and lock core back segment two parts that described lock core is pasted mutually by the plane are formed, and are axially arranged with the keyhole that cooperates with key at the lock core leading portion, are axially arranged with a plurality of radially shell fragment grooves along the lock core leading portion, and the shell fragment groove is communicated with keyhole; In the shell fragment groove, be provided with the combination shell fragment that constitutes by two shell fragments, the shell fragment middle part is provided with the tartar hole that cooperates with key, be respectively equipped with the relative boss in position in the same side of two shell fragments, between two boss, be provided with spring, be provided with the hypotenuse groove of dislocation at the opposite side relative with the boss of shell fragment; Be provided with guide groove at the axial outer wall of lock core leading portion corresponding with each shell fragment homonymy hypotenuse groove, guide groove connects the lock core leading portion and axially and with each shell fragment groove is communicated with, in guide groove, be provided with a guide pillar, the inner of guide pillar can be inserted in the hypotenuse groove of shell fragment, and its outer end was consistent with the interface of lock body and lock core leading portion when guide pillar withdrawed from the hypotenuse groove of shell fragment; Be provided with locked groove with the corresponding lock body inwall of guide groove, in locked groove, be provided with a driving lever, locked groove, driving lever extend to the lock core back segment, be provided with the linked slot that can hold the driving lever radial dimension at the lock core back segment outer wall corresponding with locked groove, driving lever is consistent with the degree of depth that guide pillar inserts hypotenuse groove on the shell fragment at the radial dimension of lock core leading portion, and the width of guide groove can hold driving lever; Between locked groove bottom and driving lever, be provided with driving lever and move resetting means.

The driving lever end of the lock core back segment part described in above-mentioned a kind of anti-prizing type lock is provided with inwardly protruded projection, can stop the friction interlock between lock core leading portion and the lock core back segment so fully.

Resetting means described in above-mentioned a kind of anti-prizing type lock can be to be provided with plural blind hole on the lock body of locked groove bottom, is equipped with successively to be used for spring and the pellet shot from a slingshot that driving lever resets in blind hole.

Resetting means described in above-mentioned a kind of anti-prizing type lock also can be separately positioned on locked groove bottom and the driving lever many compositions to and the opposite magnet of magnetic pole.

After the utility model adopts said structure, because the combined lock core that adopts the plane to paste mutually, at the lock core leading portion a plurality of combination shell fragments are set, after inserting key the shell fragment inclined plane groove is alignd with guide pillar, guide pillar could insert in the inclined plane groove, thereby driving lever is entered in the guide groove, rotate relative to lock body by key rotational lock core leading portion drive lock core back segment and unblank; When the tartar and the shell fragment of key can not be all at once, because of inclined plane groove and guide pillar do not have complete matching, guide pillar can not insert in the inclined plane groove, at this moment the outer end of guide pillar is in the place, line of demarcation of lock body and lock core leading portion, the lock core leading portion is in idling conditions, and the rotational lock core leading portion all can not make the lock core back segment rotate in any case, and the lock core leading portion does not have origin of force when idle running, can prevent powerful picking lock effectively; Simultaneously, because the inclined plane groove on each shell fragment shifts to install, be difficult to utilize insert that steel wire or other instrument are stirred and with the inclined plane groove of all shell fragments focus on the collinear position of lock core leading portion guide groove on, guide pillar is withstood by the shell fragment side all the time and can't enter in the shell fragment inclined plane groove, driving lever also can't enter in the guide groove of lock core leading portion lock core leading portion and lock core back segment are coupled together, and the lock core leading portion can only be done the idle running of 360 degree and can not drive the lock core back segment and rotate the unlatching lockset.Therefore, the utility model compared with prior art has good anti-dialling and the pick-proof performance, has solved the technical disadvantages of original traditional pellet shot from a slingshot and shell fragment tapered end effectively.
