Description

The anti-lock core of opening

The utility model relates to a kind of anti-unlatching lock core that is applied in various types of locks.

In the life, no matter be in the life now, still in the work, lock is absolutely necessary; And lock core is the indispensable important component part of lock, but, in present various types of locks, because the structure problem of lock core, be locked in the application ubiquity and such shortcoming: the anti-poor performance of opening, especially not anti-technical attack, thereby just do not have the safety precaution effect yet, bring very big hidden danger for people's life.

At the shortcoming of prior art, the purpose of this utility model is to provide a kind of anti-unlatching lock core, is applied in various types of locks, to prevent by illegal people's technical unlocking.

The purpose of this utility model is achieved through the following technical solutions: a kind of anti-unlatching lock core comprises and prevents opening keyway, anti-start button, anti-keyway, key socket, stage clip mounting, stage clip, anti-drilling steel pin, the tee T key composition opened of lock tube on lock tube, lock core, special-shaped marble group, pellet shot from a slingshot spring, pellet shot from a slingshot hole, the core; It is characterized in that: lock core is installed in the lock tube, the inwall of lock tube is provided with the anti-keyway of opening of rectangular lock tube, one side of lock core offers one group of pellet shot from a slingshot hole, all offer breach one on each pellet shot from a slingshot of special-shaped marble group, each pellet shot from a slingshot inserts respectively in the corresponding pellet shot from a slingshot hole, its export-oriented top is equipped with the pellet shot from a slingshot spring, offers the key socket that inserts for the tee T key on the lock core simultaneously; In addition, a side of lock core offers the anti-keyway of opening on the core, and anti-start button is placed in therebetween, and it is convex shape, and stage clip is located at the two ends of anti-start button, and the end of the extroversion of stage clip is provided with the stage clip mounting, and anti-drilling steel pin also is located on the lock core; The tee T key be shaped as tee T, in the front, vertically establish concave-convex surface attitude key bit; The anti-rectangular shape of keyway of opening of lock tube.

By a kind of anti-unlatching lock core of the utility model, can overcome the shortcoming of prior art, effectively prevent technical unlocking, can prevent that more ordinary people's unlatching from attacking, it is perfectly safe really to accomplish.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a three-dimensional decomposition texture schematic diagram of the present utility model;

Fig. 3 is the schematic perspective view of the utility model key.

The figure number explanation:

1, lock tube 2, lock core

3, special-shaped marble group 4, pellet shot from a slingshot spring

5, the anti-keyway of opening on pellet shot from a slingshot hole 6, the core

7, anti-start button 8, the anti-keyway of opening of lock tube

9, key socket 10, spring mounting

11, stage clip 12, anti-drilling steel pin

13, tee T key

As shown in Figure 1 and Figure 2, a kind of anti-unlatching lock core of the utility model comprises and prevents opening keyway 6, anti-start button 7, anti-keyway 8, key socket 9, stage clip mounting 10, stage clip 11, anti-drilling steel pin 12, tee T key 13 compositions opened of lock tube on lock tube 1, lock core 2, special-shaped marble group 3, pellet shot from a slingshot spring 4, pellet shot from a slingshot hole 5, the core; Lock core 2 is installed in the lock tube 1, the inwall of lock tube 1 is provided with the anti-keyway 8 of opening of rectangular lock tube, one side of lock core 2 offers one group of pellet shot from a slingshot hole 5, all offer breach one on each pellet shot from a slingshot of special-shaped marble group 3, each pellet shot from a slingshot inserts respectively in the corresponding pellet shot from a slingshot hole 5, its export-oriented top is equipped with pellet shot from a slingshot spring 4, offer key socket 9 on the lock core 2 simultaneously, tee T key 13 can insert wherein, in addition, one side of lock core 2 offers the anti-keyway 6 of opening on the core, anti-start button 7 is placed in therebetween, and it is convex shape, and stage clip 11 is located at the two ends of anti-start button 7, the end of the extroversion of stage clip 11 is provided with stage clip mounting 10, and anti-drilling steel pin 12 also is located on the lock core 2; Be illustrated in figure 3 as the schematic perspective view of tee T key 13, it is shaped as tee T, in the front, vertically establishes the key bit of concave-convex surface attitude, and the dual-side of tee T key 13 is not then established key bit.

When not inserting key, each different in nature pellet shot from a slingshot under the pressure of spring all to the key bit directive effect, make breach on all pellets shot from a slingshot be in not point-blank irregular status, make that passive be in outside all pellet shot from a slingshot breach of the anti-start button of convex can not return, protrude from the lock core cylinder and be stuck in rectangular lock tube and prevent opening in the keyway, reach the purpose of pinning; When the operation technique method was opened, anti-start button can not return, had lost feel during the contact pellet shot from a slingshot, so just can reach the purpose of preventing technical opening; In addition, the key socket of tee T can not stay activity space to unlocking tool yet, thereby the effect of auxiliary anti-start button also can reach the purpose of preventing technical opening.

When inserting key, opposite sex pellet shot from a slingshot is subjected to the effect of corresponding key bit, make the breach of all pellets shot from a slingshot all be in rule state on the straight line, make anti-start button under the stage clip effect,, fall among the breach of pellet shot from a slingshot by protruding from return under the outer state of lock core cylinder, thereby break away from the anti-keyway of opening of lock tube, form the cylindrical of one with lock core, like this, just can rotate and reach the purpose of unblanking.

In sum, be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
