Description

A kind ofly anti-open, anti-prizing type lock

Technical field

The utility model relates to a kind of tapered end, and lock core and rear lock core realize opening the shell fragment tapered end of lockset before especially a kind of the employing by linkage.

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 then blocks lock core and makes 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 order is unlocked to tapered end; And the pick-proof performance is just more unreliable, because being used for the lock core hole of insertion key now on the tapered end all is polygon, when stealer is used when inserting lock core hole with the similar instrument of key, will block lock core hole easily, as long as clamp twisting with instruments such as spanner, hawkbills, thereby pellet shot from a slingshot will appear or shell fragment is twisted into two parts or twist and mashedly make lock core occur rotating opening lockset, no matter that a kind of phenomenon more than occurring, lockset all can be opened easily by the burglar, and lockset can't play effective antitheft effect.

The utility model content

For solving above-described the deficiencies in the prior art, the utility model proposes a kind ofly anti-dial, the tapered end of pick-proof function admirable.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of tapered end, it comprises lock body, lock core, lock core and rear lock core before wherein lock core comprises again, preceding lock core with also can rotate relative to lock body in rear lock core is arranged on lock body; Wherein preceding lock core and rear lock core two parts of being pasted mutually by the plane of lock core are formed, be axially arranged with the keyhole that cooperates with key at preceding lock core, be axially arranged with a plurality of radially shell fragment grooves along preceding lock core, the shell fragment groove is communicated with keyhole, in the shell fragment groove, be provided with the combination shell fragment that is constituted by two shell fragments, the shell fragment middle part is provided with the tartar hole of matching with key, a tartar boss that matches with key tooth flower is arranged on the tartar hole, the same side of two shell fragments is provided with relative boss on the same group, be provided with the shell fragment back-moving spring between the boss, be provided with the hypotenuse groove of dislocation at the opposite side relative with the spring boss, be provided with guide groove in the preceding lock core shaft corresponding with each shell fragment homonymy hypotenuse groove to outer wall, before guide groove connects lock core shaft to the shell fragment groove, guide groove connects to rear lock core along preceding outer wall of lock core radial component, in guide groove, be provided with one group of linkage, linkage is made up of guide pillar and driving lever, linkage can be separated position (both transfer), also can be (both interlocks) of integrality, 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 preceding lock core when guide pillar withdrawed from the hypotenuse groove of shell fragment; Be provided with locked groove at the lock body inwall corresponding with preceding lock core guide groove, locked groove, driving lever extend to rear lock core, be provided with the linked slot that can hold the driving lever radial dimension at the rear lock core outer wall corresponding with locked groove, driving lever is consistent with the degree of depth of the hypotenuse groove of guide pillar insertion shell fragment at the radial dimension of preceding lock core, and guide groove can hold driving lever; Be provided with a plurality of resetting means hole in locked groove bottom, be provided with in the resetting means hole and make guide pillar and driving lever carry out the resetting means of reset movement, resetting means is made of back-moving spring and the pellet shot from a slingshot that resets.

In addition, linkage in the guide groove on the described lock core is in guide pillar and the driving lever that separates self contained function state or whole linkage status after comprising combination, wherein the inner of guide pillar is provided with the hypotenuse that matches with the hypotenuse groove, and the end that is in the driving lever in the linked slot of rear lock core is provided with inwardly protruded driving lever boss.

The beneficial effects of the utility model are: after the utility model adopts said structure, because the combined lock core that adopts preceding lock core and rear lock core plane to paste mutually, at preceding lock core a plurality of combination shell fragments are set, after inserting the phase bitting hypotenuse groove of shell fragment is alignd with the guide pillar of linkage, guide pillar could insert in the hypotenuse groove, thereby the driving lever in the linkage is entered in the guide groove, preceding lock core and rear lock core link together by linkage, and lock core rotates relative to lock body together with rear lock core and opens lockset before making by the rotation key; When the tartar of key can not be all at once, because hypotenuse groove and guide pillar do not have complete matching, guide pillar can not insert in the hypotenuse groove, at this moment the guide pillar outer end is in the place, line of demarcation of lock body and lock core, when the guide pillar in the linkage and driving lever be separated position the time, preceding lock core is in idling conditions, lock core before rotating in any case, rear lock core is rotated, and there is not origin of force during preceding Lock cylinder idling, can effectively prevent the powerful tapered end of opening, when the part of the guide pillar in the linkage partly was integrality with driving lever, guide pillar partly blocked preceding lock core, driving lever partly blocks lock body and rear lock core, can't rotate preceding lock core, when powerful the unlatching occurring, it is big to block the part area, preceding lock core is difficult to be prized, preceding exactly lock core is prized bad, and rear lock core blocks with lock body by the driving lever part, and lock core comes the interlock rear lock core to open lockset before also can't prizing by brute force; Simultaneously, because the hypotenuse groove on each shell fragment shifts to install, be difficult to utilize instrument stir hypotenuse groove with all shell fragments focus on the collinear position of preceding lock core guide groove on, the guide pillar part is withstood in the hypotenuse groove that can't enter shell fragment by the shell fragment side all the time, the driving lever part also can't enter in the guide groove of preceding lock core, linkage can't get up preceding lock core and rear lock core interlock, when linkage is separated position, preceding lock core can only be done 360 degree idle running and can not open lockset by the interlock rear lock core, when linkage was integrality, linkage was with preceding lock core, lock body, rear lock core blocks and can not rotate the unlatching lockset.Therefore, the utility model compared with prior art has good anti-dialling and the pick-proof performance, efficiently solves the technical disadvantages of original conventional lock.

In addition, the relative boss that is respectively equipped with in shell fragment the same side can guarantee that its held stationary in groove moves.
