Description
Technical field
The utility model relates to a kind of lockset, the anti-theft lock end of particularly a kind of use " V " type key.
Background technology
Tapered end is the main member of lockset.Advantages such as the cylinder type tapered end is simple in structure because of it, and is easy to manufacture and being widely used in the lockset.But, existing cylinder type tapered end causes this cylinder type tapered end very easily by the binding site place of people from keyhole or tapered end and the lock core of its lock core, with instruments such as brill or foils owing to lack antitheft means such as due anti-drilling, pick-proof, its destruction is opened or pried open, implement larceny.
Summary of the invention
The purpose of this utility model is: on the basis of existing cylinder type tapered end, provide the anti-theft lock end of a kind of improved use " V " type key.
Its technical scheme is: the anti-theft lock end of a kind of use " V " type key, comprise tapered end and lock core, it is characterized in that: described lock core is " V " type jack, and a end at " V " type jack, be provided with the anti-drilling cover of band " V " type jack, the circumferential outer edge of this anti-drilling cover is provided with the boss that the groove coupling offered in the termination with tapered end combines; Radially be provided with two groups, every group between tapered end and the lock core a plurality of corresponding hole slots that pellet shot from a slingshot is installed are all arranged; Key for be " V " type, offer the interior two groups of teeth groove that the hole slot that pellet shot from a slingshot is installed matches of two rows and lock core on it.
Its technique effect is: owing to be provided with anti-drilling cover at an end of lock core key jack, and the circumferential outer edge of anti-drilling cover is provided with the boss that the groove offered in the termination with tapered end matches, so when attempting to open lock core by the key hole drill with drill bit, anti-drilling cover can rotate along with the rotation of drill bit, make drill bit can't open lock core, thereby realize antitheft function.Simultaneously, because the circumferential outer edge of anti-drilling cover is provided with the boss that the groove offered in the termination with tapered end matches, so ought attempt the binding site by lock core and tapered end, the attempt of lock being opened with slotting tool or sheet metal can't realize.In addition, a plurality of corresponding hole slots that pellet shot from a slingshot is installed are all arranged, thereby make general key be difficult to insert this keyhole, perhaps promptly allow to key is inserted, but also be difficult to lock is opened owing between tapered end and lock core, radially be provided with two groups, every group.Therefore, this tapered end has antitheft preferably, anti-sledge function.
