Abstract

The utility model provides a lock head protective device which comprises a lock core and a lock body, wherein the lock core is provided with a protective groove along a radial direction and is provided with an oblique rib groove which is in accordance with a key and a face rib groove of a lock hole along an axial direction. A spacing spring and a protective hole clamping plate are arranged in the protective groove, and the lock body corresponding to a groove opening of the protective groove is provided with a groove of the lock body. The utility model is characterized in that the protective hole clamping plate in the protective groove is provided with a lock hole and a baffle plate of the lock hole so that a lock is always in protection. When the lock hole is opened, the protective hole clamping plate is positioned in the protective groove and the groove of the lock body, and the protective device stays in a self-locking state. When the protective hole clamping plate is completely separated from the groove of the lock body, the lock hole is locked by the baffle plate of the lock hole on a protective clamping plate so that any foreign object can not enter the lock core and a spring ball or a reed can not be touched. The special protective device can effectively prevent a lock from being unlocked without a key by a technical unlocking tool in all the countries on the world. The utility model can be widely applied to locks of which the lock hole is arranged at the circle center, such as a spring lock, a reed lock, a quantum lock, etc.

Description

Lock Protective Device and key

Affiliated technical field

The utility model relates to lock, aspect the anti-technical unlocking original design is being arranged especially.

Background technology

Known unlimited lockhole, too simple lock head structure for the person that illegally do not unblank provides the use special tool, are opened the invasion approach of lock by technological means.

The utility model content

The purpose of this utility model is in order to overcome existing tapered end easily by the deficiency of technical unlocking, and a kind of Lock Protective Device that provides and supporting key, make lock be in the protection state all the time, only holding the key of this lock just can open, even and the person that illegally do not unblank uses special tool, also can't reach the purpose of unblanking by technical means.

For achieving the above object, the utility model provides a kind of Lock Protective Device, and this device is made of lock core, lock body.It is characterized in that described lock core radially establishes 1-2 protective trough, establishes diagonal bar groove and the lockhole gluten groove that adapts with key vertically, be provided with limit spring, guard aperture clamp in the described protective trough, the lock body corresponding with the protective trough notch is provided with the lock body groove.

Described in the utility modelly establish 1 protective trough, place a guard aperture clamp in the groove, two row's lockholes are set on this guard aperture clamp, (near the limit spring end is last to last row's lockhole, can coincide with the interior lockhole of lock core down together), arrange the Back plate for lock hole that lockhole is established a complete closed lockhole down, the one side of the inside lockhole of Back plate for lock hole is the inclined-plane.

Described in the utility modelly establish 2 protective troughs, the notch direction is opposite, be arranged in parallel, place a guard aperture clamp in each groove, two row's lockholes of the intercommunication that links to each other up and down are set on the guard aperture clamp in the groove, on arrange lockhole and can communicate identically with the interior lockhole of lock core, following row's lockhole is established Back plate for lock hole (baffle plate of sealing keyhole), the one side of the inside lockhole of Back plate for lock hole is the inclined-plane, and the Back plate for lock hole complementation of two guard aperture clamps can be interior lockhole sealing.

Guard aperture clamp described in the utility model is provided with the gluten groove that is complementary with the key gluten.

Guard aperture clamp described in the utility model can slide in separately protective trough and corresponding lock body groove.

Unlatching has the key of the lock of above-mentioned protector, the key groove that it is characterized in that being provided with on the key diagonal bar and be complementary with Back plate for lock hole on the guard aperture clamp.

Key diagonal bar described in the utility model divides goes up diagonal bar, following diagonal bar.

Key diagonal bar described in the utility model, key groove be separately positioned on positive and negative two faces of key and supporting in pairs.

Key groove described in the utility model is provided with gluten.

Have lock of the present utility model, under normal conditions, open wide with the same lockhole of other locks, but the guard aperture clamp that is inlaid in the lock core protective trough is stuck in the lock body groove, even without the locking of pellet shot from a slingshot or reed, lock core also could rotate! So which type of skilled unlocking instrument no matter the person that illegally do not unblank this moment use, and adopts which type of technological means, all do not reach the purpose of unblanking.If not the guard aperture clamp is stirred in the method person of unblanking attempt, this guard aperture clamp only can slide to the one side of sealing keyhole, when the guard aperture clamp is struck when leaving the lock body groove fully, lockhole will be by the Back plate for lock hole complete closed on the guard aperture clamp, any skilled unlocking instrument all could touch pellet shot from a slingshot or reed more at this moment! Have only when the key insertion lockhole that is equipped with, lock tooth leveling on the key pellet shot from a slingshot or reed, the guard aperture clamp is under the thrust of descending diagonal bar on the key, leave the lock body groove, and the Back plate for lock hole on the guard aperture clamp enters corresponding on the key key groove, at this moment, lock core can rotate in lock body, and lock is opened.

The beneficial effects of the utility model are: have only when lockhole is sealed by the Back plate for lock hole on the guard aperture clamp, this lock just might be opened, and this moment, any foreign matter all can not enter lock core, touched pellet shot from a slingshot or reed.Therefore, the protector that this is special can effectively stop countries in the world skilled unlocking instrument no key operated to lockset, has also strengthened the uprising ability of lock simultaneously.The utility model can be widely used in lockhole locking in the center of circle such as cylinder lock, Reed lock, quantum lock.

Below in conjunction with accompanying drawing the utility model is described further.
