Description

Locking plate is locked

Technical field

The present invention relates to a kind of locking plate lock.

Background technology

As shown in Figure 1, the structure of existing locking plate lock is: it comprises in a lock body 2, lock body 2 is equipped with rotating lock cylinder 1; Lock core 1 is axially having keyhole; (generally locking plate groove is four to eight lock core 1 to be radially provided with one group of locking plate groove, spaced separated between described locking plate groove), locking plate 3 and a spring 4 of a pair stacked placement is provided with in each locking plate groove, locking plate 3 side is extended with the spring coordinated with spring 4 and hangs angle 32, there is inner screw tooth hole at the middle part of locking plate 3, the spring extension angle 32 being placed on two locking plates 3 in a locking plate groove is staggered relatively, the spring that spring 4 two ends are resisted against two locking plates 3 is respectively hung on angle 32, the advantages such as above-mentioned Locking plate lock has manufacturing process fairly simple, are widely used; But above-mentioned locking plate lock has following shortcoming:

1, extract key, locking plate is under the pushing of spring, and locking plate stretches out lock core and enters lock core cover groove, can not be greater than the rotation of 10 degree about blocking lock core;

2, lock core condition of work is, the spring of locking plate is hung angle and can not be collided, and spring maximum compression distance will ensure;

3, the little cisco unity malfunction of this lock core diameter, locking plate is also uncompressed to put in place, limits the stroke between two locking plates, and the spring of upper and lower locking plate is hung angle and just contacted, and can not meet the requirement of Long travel locking plate lock.

So, can large-size be had after locking plate lock adopts said structure, when installing space is less, locking plate cannot be used to lock.

Summary of the invention

Technical problem to be solved by this invention is to provide that a kind of structure is simple, the locking plate of ease of assembly lock.

For solving the problems of the technologies described above, the invention provides a kind of locking plate lock, comprise lock body, lock core and some locking plates, lock core is contained in lock body, lock core is axially having keyhole, lock core has some locking plate grooves, lock body is provided with the only locked groove that twice are symmetrical in locking plate groove, some locking plate correspondences are contained in locking plate groove, described locking plate has inner screw tooth hole, each locking plate side is extended with the spring coordinated with spring and hangs angle, described locking plate groove comprises locking plate chamber and at least one agrees with the spring cavity of spring shape, locking plate chamber and twice are stopped locked groove and are connected, spring cavity is in locking plate groove side, the spring of locking plate is hung angle and is stretched in spring cavity, the spring that described spring one end is resisted against locking plate is hung on angle, the described spring other end is resisted against on the chamber wall of spring cavity.

After adopting such structure, spring maximum compression distance is guaranteed, and key inserts and extracts light smooth and easy, reduces the difficulty of assembling, can be applied directly in the lock core of minor diameter.

Each locking plate groove of this locking plate lock comprises a locking plate chamber and two spring cavitys, and two spring cavitys are in the both sides in locking plate chamber respectively; Be placed with two locking plates in each locking plate groove, the spring of two locking plates is hung angle and is stretched in two spring cavitys respectively, and the spring that each spring one end is resisted against locking plate is hung on angle, and the spring other end is resisted against on the chamber wall of spring cavity.

After adopting such structure, locking plate spring symmetric configuration, when opening this locking plate lock, in same locking plate groove, do not meet mutually in the spring extension angle of two locking plates.

Each locking plate and the corresponding only locked groove of this locking plate lock are provided with two anti-dial hooks of width symmetry, and on each only locked groove, corresponding position has two anti-dial projections that can be suitable with described two anti-dial hooks.

After adopting such structure, side from locking plate to its width deflection time, the anti-dial hook of homonymy will be stuck in the anti-dial projection suitable with it, radial direction pulls locking plate, locking plate can not depart from from stopping locked groove, cannot unblank when not having correct key, have correct key only and locking plate just can be made to unblank from stopping disengaging locked groove, the anti-dial performance of this locking plate lock is strong, security reliability good.

Detailed description of the invention

As shown in Figures 2 to 4

This lockset comprises lock body 2, is contained in lock cylinder 1 in lock body 2 and eight locking plates 3 rotationally.

Lock core 1 is axially having keyhole, lock core 1 is radially provided with four locking plate grooves 12, spaced separated between four locking plate grooves 12, each locking plate groove 12 comprises the spring cavity 12b that a locking plate chamber 12a and two agreeing with locking plate 3 profile agrees with spring 4 profile, and two spring cavity 12b are in the both sides of locking plate chamber 12a respectively.

Lock core 1 is sleeved in lock body 2, and lock body 2 is provided with the only locked groove 21 that twice are symmetrical in locking plate groove 12, and locking plate chamber 12a and twice are stopped locked groove 21 and communicated.

Each locking plate groove 12 is built with two locking plates 3 and two springs 4, there is inner screw tooth hole 31 at the middle part of each locking plate 3, the inner screw tooth hole 31 of each locking plate 3 and locking plate 3 thereof is all unique, each locking plate 3 side is extended with the spring coordinated with spring 4 and hangs angle 32, and the spring of two locking plates 3 in a locking plate groove 12 is hung angle 32 and is stretched in two spring cavity 12b respectively, the spring that each spring 4 one end is resisted against locking plate 3 is hung on angle 32, and spring 4 other end is resisted against on the chamber wall of spring cavity 12b.

Each locking plate 3 and corresponding being only provided with between locked groove 21 can avoid this lock by the dial-proof device of technical unlocking.Described each locking plate 3 one end and corresponding only that end that locked groove 21 is slidably matched are provided with two anti-dial hooks 33 of width symmetry, on each only locked groove 21 corresponding position have can with suitable two anti-dial protruding 22 of described two anti-dial hooks 33, described anti-dial hook 33 and suitable with it anti-dial protruding 22 constitutes dial-proof device; Burglar by unlocking tool make side from locking plate 3 to its width deflection time, the anti-dial hook 33 of homonymy will be stuck in suitable with it anti-dial protruding 22, such burglar just radial direction can not pull locking plate 3, locking plate 3 can not depart from from stopping locked groove 21, make do not have the burglar of correct key to unblank, having correct key only just can make locking plate 3 unblank, so the anti-dial performance that this locking plate 3 is locked is strong, security reliability good from stopping disengaging locked groove 21.

Above-described is only one embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
