Abstract
The utility model relates to an anti-pulling out locking sheet lock which comprises a lock body and a cylindrical lock plug which is rotatablely assembled in the lock body, wherein, a key hole is axially opened on the lock plug which is provided with a plurality of locking sheet grooves, a pair of overlapped locking sheets arranged in each locking sheet groove and springs connected between the pair of the locking sheets; the lock body is provided with two stopping locking grooves which are symmetric with the locking sheet groove; each locking sheet is glidingly matched with the corresponding locking sheet grooves and the stopping licking grooves; an anti-pulling out device which can prevent the lock from being unlocked technically is arranged between each locking sheet and the corresponding stopping locking groove. By adopting the structure, as the anti-pulling out device which can prevent the lock from being unlocked technically is arranged between each locking sheet and the corresponding stopping locking groove, the defect that the existing locking sheet lock has no anti-pulling out device is overcome; therefore, a theft without a correct key is prevented from unlocking the key which can only be unlocked by the correct key, thus the locking sheet lock has high anti-pulling out performance.
Description
Technical field
The utility model relates to a kind of lockset, particularly relates to a kind of anti-strong anti-locking plate lock of dialling of performance of dialling.
Background technology
The structure of existing locking plate lock is: it comprises is equipped with rotating lock cylinder in a lock body, the lock body; Lock core is axially having keyhole; (the locking plate groove is four to eight generally speaking radially to be provided with one group of locking plate groove on the lock core, it is separated to separate each other between the described locking plate groove), be provided with locking plate and a spring that is connected between two locking plates of a pair of stacked placement in each locking plate groove, the middle part of locking plate is porose, side end has outside projection, the two ends of spring contact with projection on two locking plates, and lock body is provided with the locked groove that ends that twice axially are symmetrical in the locking plate groove, and each locking plate is with corresponding locking plate groove and end locked groove and be slidingly matched.For the locking plate of every pair of stacked placement, when two locking plates overlapping the most after a little while (during locking states), each locking plate is arranged in the locking plate groove simultaneously and ends locked groove, and when two locking plates overlapping when maximum (with correct key unlocking time), the two locking plates while only is arranged in the locking plate groove.
Because existing locking plate lock does not have to avoid the dial-proof device by technical unlocking, like this, may detect the spacing of locking plate and move radially degree by keyhole, the burglar uses unlocking tools such as steel disc (silk), hair clip, master key to inject in the keyhole easily and touches, set locking plate correctly and unblank (that is: by unlocking tool locking plate to be changeed to a lateral deviation of its width, and radially spur locking plate and it is broken away from from end locked groove and only be arranged in the locking plate groove), therefore, the anti-group performance of existing locking plate lock is weak, security reliability is poor.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of anti-strong anti-locking plate lock of dialling of performance of dialling is provided.
For achieving the above object, the utility model provides a kind of anti-locking plate lock of dialling, it comprises lock body, is contained in lock cylinder in the lock body rotationally, lock core is axially having keyhole, lock core is provided with some locking plate grooves, is loaded on the locking plate of a pair of stacked placement in each locking plate groove and is connected in this to the spring between the locking plate, lock body is provided with the locked groove that ends that twice are symmetrical in the locking plate groove, each locking plate is with corresponding locking plate groove and end locked groove and be slidingly matched, and each locking plate can avoid this lock by the dial-proof device of technical unlocking with only being provided with between the locked groove accordingly.
Adopt after the above structure, because each locking plate and corresponding only being provided with between the locked groove can avoid this lock by the dial-proof device of technical unlocking, overcome the defective that does not have dial-proof device in the existing locking plate lock, like this, making does not have the burglar of correct key to unblank, have correct key only and just can unblank, so the anti-group performance of this locking plate lock is strong.
That end that described each locking plate and corresponding only locked groove are slidingly matched is provided with two anti-hooks of dialling of width symmetry, each end on the locked groove corresponding position have can with described two anti-two suitable anti-allocating slots of hook of dialling, describedly anti-ly dial hook and the anti-allocating slot suitable with it formed dial-proof device.
Perhaps, that end width stage casing that described each locking plate and corresponding only locked groove are slidingly matched has anti-allocating slot, each ends, and corresponding position is provided with and can dials hook with suitable the preventing of described anti-allocating slot on the locked groove, have a corresponding anti-hook of dialling in each anti-allocating slot, described anti-allocating slot and anti-the dial hook suitable with it have been formed dial-proof device.
Moreover, that end that described each locking plate and corresponding only locked groove are slidingly matched is provided with two the first anti-hooks of dialling of width symmetry, each end on the locked groove corresponding position have can with described two first anti-two the first suitable anti-allocating slots of hooks of dialling, that end width stage casing that each locking plate and corresponding only locked groove are slidingly matched has the second anti-allocating slot, each end on the locked groove corresponding position be provided with can with the second suitable anti-hook of dialling of the described second anti-allocating slot, have the one corresponding second anti-hook of dialling in each second anti-allocating slot, described first anti-hook and the first anti-allocating slot suitable dialled with it, the described second anti-allocating slot and second anti-the dial hook suitable with it have been formed dial-proof device.
