Description

A kind of monoblock type lock core

Technical field

The utility model relates to a kind of monoblock type lock core.

Background technology

At present, existing common tapered end anti-theft effect is poor, and lock core is relatively easily opened, and also relative complex of structure, production cost is high.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of monoblock type lock core.

For addressing the above problem, the technical scheme that the utility model adopts is:

A kind of monoblock type lock core, comprises lock core, lock body, shell, pellet, spring, it is characterized in that: described lock core is provided with cannelure cover, described lock body is provided with protruding torus, and described lock core coordinates with torus, and described lock core and torus are provided with multiple marble holes, in described marble hole, be provided with spring and pellet, described spring length difference, described shell is connected with lock body, and described lock core cover is on lock body.

Preferred as one, described shell and lock core are matched in clearance.

Preferred as one, described lock core is provided with keyhole.

Preferred as one, described lock body is provided with keyhole.

Preferred as one, described lock body and shell are bolted.

Preferred as one, described lock core one end is provided with cam.

Preferred as one, lock core and torus are matched in clearance.

Owing to having adopted technique scheme, compared with prior art, the utility model is by the setting of monoblock type lock core, make tapered end there is good anti-technology unlocking performance, increased the fastness of lock core, easy to install, safe and reliable, simultaneously simple in structure, easy to manufacture, with low cost, can be for built-in lock, safe-guard door lock, chain lock, safe lock, on the multiple lockset such as lock, has higher matching degree.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.

Detailed description of the invention

Embodiment:

As Figure 1-4, a kind of monoblock type lock core, comprises lock core 1, lock body 2, shell 3, pellet 4, spring 5, is characterized in that: described lock core 1 is provided with cannelure cover 11, and described lock body 2 is provided with torus 21, described lock core 1 coordinates with torus 21, described lock core 1 and torus 21 are provided with multiple marble holes 6, are provided with spring 5 and pellet 4 in described marble hole 6, described pellet 4 length differences, described shell 3 is connected with lock body 2, and described lock core 1 covers on lock body 2.

Further, described shell 3 is matched in clearance with lock core 1, and the matched in clearance by shell 3 with lock core 1, has ensured that the rotation of lock core 1 is unblanked.

Further, lock core 1 is matched in clearance with torus 21, and the matched in clearance by lock core 1 with torus 21, has ensured that the rotation of lock core 1 is unblanked.

Further, described lock core 1 is provided with keyhole 7, and described lock body 2 is provided with keyhole 7, and the keyhole 7 on lock core 1 communicates with the keyhole 7 on lock body 2.

Further, described lock body 2 is connected by bolt 8 with shell 3, by the setting of bolt 8, has reached being fixedly connected with of lock body 2 and shell 3.

Further, described lock core 1 one end is provided with cam 12, by the rotation of cam 12, drives unlocking mechanism, unblanks thereby realize.

As shown in Figure 3, in the time that keyhole 7 does not insert key, on the interface of the part pellet 4 in marble hole 6 in lock core 1 and annular solid 21, lock core 1 and lock body 2 are tied down, lock core 1 can not rotate around torus 21, because lock can not be opened.

As shown in Figure 4, when inserting when key, shaggy tooth on the key changes pellet 4 positions in marble hole 6, makes the end face of the pellet 4 of original bolt on interface and interface to it, rotate key and can make lock core 1 rotate around torus 21, thereby drive unlocking mechanism that lock is opened.

In the time that use instrument carries out technology unlocking, because the lock core 1 and the torus 21 that are enclosed within on torus 21 have inside and outside two interfaces, disturb the operation of unlocking tool, cannot make accurately end face and the interface alignment of the pellet 4 of bolt on interface, lock core 1 can not rotate around torus 21, can not realize and unblanking, increase security.

Owing to having adopted technique scheme, compared with prior art, the utility model is by the setting of monoblock type lock core, make tapered end there is good anti-technology unlocking performance, increased the fastness of lock core, easy to install, safe and reliable, simultaneously simple in structure, easy to manufacture, with low cost, can be for built-in lock, safe-guard door lock, chain lock, safe lock, on the multiple lockset such as lock, has higher matching degree.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
