Abstract
The utility model is a burglarproof lock core. Such a burglarproof lock core is mainly a locked shaft tube containing a rotation piece, a driven lock piece, an inside lock piece, a compressed elastic piece and an outer lock piece assembled in turn. A lock core shell is outside the locked shaft tube and a lock rod is in the gap of the outside wall of the locked shaft tube. When the correct key is plugged in, the lock rod slides to the space between the locked shaft tube and the lock leaf, which makes the locked shaft tube rotate in the lock center and lock. Therefore, because these lock plates are round pieces and compressed elastic piece brings about lock plates to move upwards, the compression configuration space makes thief can not unlock with the incorrect key. And because these lock plates are in the locked shaft, the lock core can not be damaged by the incorrect key.
Description
Technical field
The utility model particularly designs at the structure that core proposed in this lockset about a kind of lockset.
Background technology
At present existing lockset is according to factors such as different objects, environment for use and functions, and respectively being provided with multiple style provides the user to comply with it requiredly to choose use.In the design of lockset, core is the core component that whether control locks in the lockset, and it is related to the theftproof performance of whole lockset, so the lockset manufacturer is engaged in research and development to the many manpowers of structure design input of core.
In existing numerous core designs, the core that one type is arranged is a locking plate formula lock core structure of adorning most locking plates in adopting, this locking plate formula core mainly is the lock shaft tube that is provided with most locking plates in a core shell in the installing one, and in set first breach of lock shaft tube sidewall the installing one lock bar of pulling, the inside wall of this core shell is provided with a corresponding locking bar recess of locking the bar of pulling, those locking plate lateral margins convex with a protuberance and insert the second set breach of lock shaft tube sidewall, and those locking plates are provided with the pull recessed edge of locking bar of bar of corresponding lock with respect to the periphery diverse location place of the keyhole of centre.
Aforesaid core is applied in the lockset, when this core under locking state, the recessed edge of the locking bar of those locking plates is non-to be positioned at same linear position, and the lock bar of pulling is positioned between lock shaft tube and core shell, the lock shaft tube can't be rotated unblank; When so that correct key that should core is inserted the keyhole of those locking plates, can make the recessed edge of locking bar of those locking plates just aim at first breach of lock shaft tube, at this moment, in the time of promptly can key turns lock shaft tube, this lock bar of pulling can be passed to the locking bar recess that breaks away from the core shell, first breach of dislocation lock shaft tube and the locking bar of those locking plates are recessed intermarginal, and unblank.
Though but aforementioned locking plate formula core is to adorn most locking plates as the pull usefulness of control of lock in it, and the recessed edge position difference of the locking bar that can utilize locking plate is made multiple various combination, yet, the locking plate periphery of this core is to convex with protuberance to be placed in the second set breach of lock shaft tube sidewall, when the burglar stretches into when rotating by force in the core with other non-correct keys or rectangular thing, this core is promptly destroyed, removes the not good shortcoming of anti-theft security, and people must will put in order at least afterwards and organize core and changed.
The utility model content
Main purpose of the present utility model is to provide a kind of anti-theft lock core, wishes design whereby, makes it can overcome the problem that previous existing locking plate formula core easily destroys for the robber.
For reaching above-mentioned purpose, the technical scheme that the utility model proposed be make this anti-theft lock core mainly be in a lock shaft tube, assemble revolving fragment in regular turn, drive locking plate, locking plate etc. outside locking plate, compression elastic piece reach in the number, the sheathed core shell in the lock shaft tube outside, in addition be provided with the lock bar of pulling in the indentation, there of lock shaft tube sidewall, and can be controlled protrude out outwardly to pull and be the state of locking with lock core shell from this breach, or after correct key inserts, lock that bar slides onto lock shaft tube and this locking plate is pulled between recess can to make this lock pull, and the lock shaft tube can be rotated in the core shell unblank.
The utility model is by the design of preceding taking off technical scheme, compared to the lock core structure that prior art disclosed, its characteristics are: core of the present utility model is after locking, if the robber inserts in this core attempt when unblanking with non-correct key, because of this non-correct key shape fail with those in locking plate and the lock of drive in the locking plate through hole of pulling be complementary fully, the lock bar of pulling still is between lock shaft tube and core shell, this lock shaft tube makes outside can't be unblanked by turn, the more important thing is, the utility model is the outer locking plate that further makes this core, interior locking plate and drive locking plate etc. are taked circular lamellar body design, compression elastic piece provides to drive and moves movable space on the locking plate, if the robber inserts in the rotating process with non-correct key, only make this outer locking plate, interior locking plate and drive locking plate dally in this lock shaft tube, improve the degree of difficulty that this core is illegally opened, and can effectively avoid this core destroyed.
