Abstract

The present invention provides a kind of lock core protection mechanism, including tapered end shell, the tapered end being embedded in tapered end shell and the inner core for being socketed on tapered end shell exterior, tapered end shell is fixed with inner core, a body is equipped in the outside of inner core, cooperation is socketed between body and inner core, one end of body is equipped with the hole slot being inserted into for key, and hole groove edge forms the limiting unit for preventing tapered end from skidding off.Beneficial effects of the present invention: the present invention by increase body can further ensure that tapered end is not taken out surprisingly, even if so that criminal bore expense nail can not take out tapered end, enhance the destruction difficulty of lock core, improve the anti-theft performance of lock core.

Description

A kind of lock core protection mechanism

Technical field

The invention belongs to lock technology field more particularly to a kind of protection mechanisms of lock core.

Background technique

Existing lock generally comprises tapered end, inner core, tapered end shell, and principle is that tapered end can be after matched key insertion tapered end Rotation, tapered end shell are embedded in interior in-core, and are by one or more pins between tapered end shell and inner core in tapered end shell Locking, so that it will not fall off, in the case where key can not unlock, pin would generally be bored by criminal by electric drill, so Tapered end and tapered end shell are integrally directly separated into inner core afterwards, prevent it from the purpose that plays locking.

Summary of the invention

Technical problem to be solved by the invention is to provide a kind of lock core protection mechanisms, prevent tapered end from surprisingly being taken out.

The present invention is achieved by the following technical solution:

A kind of lock core protection mechanism including tapered end shell, the tapered end being embedded in tapered end shell and is socketed on outside tapered end Inner core outside shell, tapered end shell are fixed with inner core, are equipped with a body in the outside of inner core, socket is matched between body and inner core It closes, one end of body is equipped with the hole slot being inserted into for key, and hole groove edge forms the limiting unit for preventing tapered end from skidding off.

Further, the body is equipped with fixed position and moving position, and inner core is equipped with the fixed bit with body The positioning region matched with moving position is set, fixation position and activity bit joined together by positioning region are switched by rotation body It sets, is moved when the fixation position that positioning region corresponds to body then limits body to body extraction direction.

Further, block piece is equipped at fixed position or moving position.The block piece is embedded in the activity of body Position locks positioning region in fixed position.

Beneficial effects of the present invention: the present invention can further ensure that tapered end is not taken out surprisingly, makes by increasing body Tapered end can not be taken out even if obtaining criminal and boring expense nail, enhances the destruction difficulty of lock core, improves the anti-theft performance of lock core.

Specific embodiment

Below with reference to embodiment, the invention will be further described.

Embodiment

A kind of lock body as shown in FIG. 1 to FIG. 3, the lock body include chain assemblies 6, button 5, Pi Zhu 4, iron head 7, bluff piece 8, Turntable 11, steel ball 10, plastic shell 2, tapered end 9, tapered end shell (not shown) and inner core 12 (are existing with upper-part Technology, principle are also the prior art, are not set forth in detail herein), it should be noted that lock core is provided with outside inner core 12 Protection mechanism, the lock core protection mechanism include the body 13 being equipped in the outside of inner core 12, are covered between body 13 and inner core 12 Cooperation is connect, one end of body 13 is equipped with the hole slot being inserted into for key 1, and hole groove edge forms the limiting unit for preventing tapered end from skidding off 131, the setting of limiting unit can guarantee that tapered end 9 will not skid off, and the body 13 is equipped with fixed position 132 and moving position 133, inner core 12 is equipped with the positioning region 121 matched with the fixation position 132 of body 13 and moving position 133, passes through rotation Body 13 switches fixation position 132 and moving position 133 joined together by positioning region 121, when consolidating for the corresponding body in positioning region 121 Positioning set 132 limit body 13 to body 13 extract direction move.Criminal does not know lock core internal structure, will not or be difficult to Body 13 is extracted, the pin first destroyed between plastic shell 2 and iron head 7, iron are also required in the case where knowing internal structure Pin between first 7 and body 13, then the pin between tapered end shell and inner core 12 is destroyed, then rotating body 13 again could incite somebody to action Tapered end 9 is extracted, therefore the lock core is not easy to be destroyed, and safety is good.

Fixation position 132 on the body 13 is connected to moving position 133, and whole L-shaped slot.The positioning Portion 121 is boss, and the design of L-shaped groove is not only easy to process quick, also more convenient when assembly.Save the cost.

In order to further increase the safety of body, block piece is equipped at fixed position or moving position.The block piece It is embedded in the moving position of body, locks positioning region in fixed position.The setting of block piece 3, must so that body 13 can not rotate Need dismantle or destroy block piece could rotate body, to extract body, removing or destroy block piece inherently has centainly Difficulty, and be additionally provided with iron head outside body, fixed between iron head and body also by pin, it is every when destroying A link cannot be jagged, and each link can be blocked by burr in the case where jagged, also result in body cannot rotate and It takes out, has further ensured tapered end.

In order to confuse criminal, on body 13 be equipped with through-hole 134, and the exposed tapered end shell of interior core outer surface with it is interior The fixed bit of core, the through-hole 134 through-hole under the fixation position that positioning region is in body are communicated with fixed bit.The design be for It allows criminal to take for boring the pin opened between inner core and tapered end shell and can extract tapered end, plays the role of fascination, allow it It can not unlock.

In order to improve the intensity of body, the body is designed as metal material and is made.

The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, those ordinary skill in the art's simply changes It is all within protection scope of the present invention with replacement.
