Description

Lock core
Technical field
The utility model relates to field of lockset, is specifically related to a kind of lock core.
Background technology
Lock core is the major part controlling lock unlatching, is the heart of lockset, refers to can rotate and the core driving locking bolt to move with key is supporting; Existing a kind of lock core, is coordinated with the lock core blade in lock core by mill teeth on the key, reaches the object of unblanking; This lock core is divided into interior mill teeth lock core and outer mill teeth lock core according to the position difference of mill teeth on the key, and the key tooth milling of interior mill teeth lock core is positioned at the middle part of key, and mill teeth on the key coordinates with the projection in the middle part of lock core blade key hole; The key tooth milling of outer mill teeth lock core is then distributed in the both sides of key, mill teeth on the key coordinates with the projection of lock core blade key hole edge, and to be interior mill teeth lock core or outer mill teeth lock core be all uses mill teeth on the key to control lock core blade to move left and right in lock core, when key inserts lock core completely, V slot on all lock core blades is in same linear position, make clamping block bottom can enter V groove, clamping block is separated with sleeve, make lock core follow key turns, thus reach the object of unblanking; But no matter be interior mill teeth lock core or outer mill teeth lock core, its " put and open by mistake " function is all not enough, has and higher open by mistake risk.
Utility model content
The purpose of this utility model is to provide a kind of avoiding improper opening, theftproof performance better lock core.
The utility model object realizes like this.
A kind of lock core, comprise plug body, clamping block, sleeve and lock core blade, plug body is arranged in sleeve, clamping block is arranged in plug body, clamping block upper end protrudes from plug body and is positioned at the lock slots of sleeve, the keyhole that described lock core blade comprises blade body and formed in blade body, blade body upper end is formed with the V-shaped groove coordinated with clamping block, and side, blade body lower end is formed with spring base; Keyhole upper center is formed with the first projection coordinated with mill teeth in key, and keyhole upper end edge is formed with the second projection coordinated with the outer mill teeth of key, and lock core blades installation is in plug body.
The utility model can also be perfect further by the following technical solutions.
Described plug body is arranged with blades installation hole, is being provided with in each blades installation hole one just, anti-two pieces of lock core blades.
The spring eye relative with spring base is also provided with below described blades installation hole, the first spring is provided with between spring base and spring eye, first spring makes lock core blade can to plug body two end motion when not inserted by key, until lock core blade outer end arrives to inside sleeve.
Also be provided with the second spring between described clamping block and lock slots, under the effect of the second spring, clamping block upper end protrudes from plug body and is positioned at the lock slots of sleeve.
The utility model is work like this.
When lock core is in the lock state, insert key, interior mill teeth on the key and outer mill teeth coordinate with the first projection of lock core blade and the second projection respectively, lock core blade is moved left and right in plug body, and when key inserts lock core completely, the V slot on all lock core blades is in same linear position, make clamping block bottom can enter V groove, at this moment clamping block is separated completely with sleeve, and plug body can follow key turns, thus reaches the object of unblanking; If other key, when inserting lock core, will be stopped by the first projection on lock core blade and the second projection, other keys can not be inserted in lock core, stop the possibility opened by mistake thoroughly, and on lock core blade, be provided with the first projection and the second projection simultaneously, cause the process of unblanking more complicated, the difficulty of technology unlocking is improved further, reduces by the possibility of people's technology unlocking.
The beneficial effects of the utility model are as follows.
(1) the utility model is by changing the structure of lock core blade, lock core blade is provided with the first projection and the second projection, first projection and the second projection need simultaneously with on the key in mill teeth and outer mill teeth coordinate and just can open lock, therefore substantially increase the avoiding improper opening function of lock core, also improve the anti-technology unlocking performance of lock core simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is lock core blade construction schematic diagram.
Fig. 3 is the inside and outside mill teeth schematic diagram of key.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described further.
Composition graphs 1 to Fig. 3 is described in detail to embodiment: a kind of lock core, comprise plug body 1, clamping block 2, sleeve 3 and lock core blade 4, plug body 1 to be arranged in sleeve 3, clamping block 2 to be arranged in plug body 1, the second spring 21 is also provided with between described clamping block 2 and lock slots 31, under the effect of the second spring 21, clamping block 2 upper end protrudes from plug body 1 and is positioned at the lock slots 31 of sleeve 3, the keyhole 42 that described lock core blade 4 comprises blade body 41 and formed in blade body, blade body 41 upper end is formed with the V-shaped groove 43 coordinated with clamping block 2, side, blade body 41 lower end is formed with spring base 46, keyhole 42 upper center is formed with the first projection 44 coordinated with mill teeth in key 51, keyhole 42 upper end edge is formed with the second projection 45 coordinated with the outer mill teeth 52 of key, described plug body 1 is arranged with blades installation hole 12, is being provided with in each blades installation hole 12 one just, anti-two pieces of lock core blades 4, also be provided with the spring eye 11 relative with spring base 46 below described blades installation hole 12, between spring base 46 and spring eye 11, be provided with the first spring 47.
When lock core be in not using state time, under the effect of the first spring 47, the lock core blade 4 of plug body 1 both sides separates respectively to both sides, the lower end of clamping block 2 is positioned on lock core blade 4, the upper end of clamping block 2 is positioned at the lock slots 31 of sleeve 3, at this moment, plug body 1 can not in sleeve 3 rotate, lock core is in the lock state; Insert key 5, interior mill teeth 51 on key 5 and outer mill teeth 52 coordinate with lock core internal cylinder blade 4 first projection 44 and the second projection 45 respectively, make lock core blade 4 in lock core, follow mill teeth 51 and outer mill teeth 52 on key 5 to move left and right, when key 5 inserts lock core completely, V-shaped groove on all lock core blades 4 43 is in alignment and be in below clamping block 2, make clamping block 2 bottom under the action of the spring 21 can enter V-shaped groove 43, at this moment clamping block 2 is separated completely with sleeve 3, plug body 1 can be followed key 5 and be rotated, thus reaches the object of unblanking.
If other key, when inserting lock core, due to the mill teeth that other keys do not coordinate with the first projection 44 and the second projection 45, will be stopped by the first projection 44 on lock core blade 4 and the second projection 45, make it can not insert in plug body 1, stop the possibility opened by mistake thoroughly, and on lock core blade 4, be provided with the first projection 44 and the second projection 45 simultaneously, cause the process of unblanking more complicated, the difficulty of technology unlocking is improved further, reduces by the possibility of people's technology unlocking.
