Abstract

The utility model relates to an anti-drilling structure of a lock core. A transverse connection section which is in parallel with the surface of the lock core is arranged between the end portion of a key and a key handle, a lock core sleeve is provided with an end cap which is coated on the surface of the lock core, intervals for the key transverse connection section to circumferentially move is arranged between the inner surface of the top portion of the end cap and the surface of the lock core, the end cap is provided with a corresponding key jack and can open holes through the key transverse connection section, and the end cap is provided with a center hole which is communicated with the bottom end of an open hole for the key handle to circumferentially move. By adopting the key with the transverse connection section, the anti-drilling structure aims at leading the key jack to circumferentially move along the key into the intervals between the end cap and the surface of the lock core in the opening process of lock cores. When drilling tools damage billiard structures of lock cores, the drilling tools are blocked by the end cap and cannot poke the lock core to circumferentially move, thereby effectively avoiding improper unlocking of drilling lock cores. The anti-drilling structure of the lock core has the outstanding advantages of simple structure, safety and reliable protection effects, and is particularly applicable to various car locks.

Description

A kind of drilling-preventing structure of lock core

Technical field

The utility model belongs to lockset, particularly relates to a kind of drilling-preventing structure of lock core.

Background technology

In the known technology, for preventing to use bradawl to destroy the generation that lock core is implemented theft, a kind of lock core drilling-preventing structure is that the lock core cover is provided with and covers plug face fully and leave at interval anti-drilling lid with plug face, and the flat opening key probes into the lock core key jack from the interval between anti-drilling lid and the plug face.Above-mentioned lock core drilling-preventing structure uses bradawl destruction lock core to have certain good effect for preventing, but uses the method for key to run counter to normality and feel inconvenience.

Summary of the invention

The utility model is to exist the method for using key to run counter to the technical problem that normality is felt inconvenience for solving the lock core drilling-preventing structure that the anti-drilling lid of above-mentioned flat opening key and plug face thereof constitutes, and provide a kind of simple in structure, make conveniently, a kind of drilling-preventing structure of lock core that security protection is reliable for effect.

The utility model is taked following technical scheme for achieving the above object: this drilling-preventing structure is made up of lock core cover and lock core with arc key hole, it is characterized in that, be provided with the horizontal section of connecing that is parallel to plug face between the end of its insertion arc key hole of described key and the key handle, described lock core is arranged with the end cap that covers plug face, be provided with the interval of moving between the inner surface at end cap top and the plug face for the horizontal section of the connecing circumference of key, described end cap is provided with corresponding key hole also can be by the perforate of the horizontal section of connecing of key, and end cap is provided with and is communicated with this perforate bottom, the centre bore that supplies the key handle circumference to move.

The utility model can also be taked following technical measures:

Be provided with the gap between the interior bead of described centre bore and the key handle that circumference moves.

The beneficial effects of the utility model and advantage are: this drilling-preventing structure adopts the key have the horizontal section of connecing, its objective is that the key hole that makes in the lock core opening process moves in the interval of end cap and plug face with the circumference of key.When take place using the bradawl instrument to destroy the billiards structure of lock core, the bradawl instrument stops by end cap and can not stir the lock core circumference and move, thereby avoided the improper generation of unblanking of bradawl lock core effectively.The utlity model has outstanding advantage relatively simple for structure, that security protection is reliable for effect, be specially adapted to various locks and use.

Drawing reference numeral: 1 key, the 1-1 key end, the horizontal section of connecing of 1-2,2 lock cores, the 2-1 key hole, 2-2 lock core cover, 3 lock bodies, the 3-1 end cap, the 3-1-1 perforate, the 3-1-2 centre bore, 4 at interval.

The specific embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.

As shown in Figure 1, 2, 3, the key 1 of present embodiment inserts between the key end 1-1 of arc key hole and the key handle at it and is provided with the horizontal section of the connecing 1-2 that is parallel to plug face.

Shown in Fig. 4,5, lock body 3 is provided with the end cap 3-1 that covers lock core 2 surfaces, and end cap 3-1 and lock body 3 are one.Be provided with the interval 4 that the horizontal section of the connecing 1-2 circumference for key moves between the inner surface at end cap 3-1 top and the plug face.End cap 3-1 is provided with corresponding key hole 2-1 also can be by the perforate 3-1-1 of the horizontal section of connecing of key, and end cap 3 also is provided with the centre bore 3-1-2 that is communicated with this perforate 3-1-1 bottom, supplies the key handle circumference to move.Be provided with the gap between the interior bead of centre bore 3-1-2 and the key handle that circumference moves.

Shown in Fig. 4,5,6, the also perforate 3-1-1 by end cap 3-1 of the horizontal section of the connecing 1-2 of key 1 when the key end 1-1 of key 1 is inserted arc key hole 2-1, this moment key 1 the position of the horizontal section of connecing 1-2 with 4 (between the interior beads of Fig. 6 broken circle and centre bore 3-1-2) are corresponding at interval.Drive lock core 2 by key 1 and promptly unblank for 90 ° or 180 ° with the rotation of Fig. 6 direction of arrow, the horizontal section of the connecing 1-2 of key 1 circumference in interval 5 moves in the process of unblanking, and key handle moves along bead circumference in the centre bore 3-1-2 of end cap 3-1.

When take place using the bradawl instrument to destroy the billiards structure of lock core 2, the bradawl instrument stops by the perforate 3-1-1 of end cap 3-1 and can not stir the lock core circumference and move, thereby avoided the improper generation of unblanking of bradawl lock core effectively.
