Abstract
The invention relates to an annular keyhole lock container which comprises a lock body, a lock core, a spring mechanism and a key, wherein the lock core is in movable fit with the lock body and is provided with an annular keyhole; a drilling prevention pin is arranged in the middle of the annular keyhole, and the key is an annular key or a semiannular key; and when in use, the annular key or the semiannular key is inserted into the annular keyhole, and the key rotates to unlock an anti-theft lock. Because the keyhole of the annular keyhole lock container has the annular structure, and the drilling prevention pin is arranged in the spring mechanism in the lock core and used for separating a left spring and a right spring and separating a front spring and a back spring, a thief is difficult to simultaneously pry the left spring and the right spring or the front spring and the back spring in the annular keyhole of the lock core by using a universal key, thereby increasing the difficulty of unlocking the lock container and improving the anti-theft performance of the anti-theft lock.
Description
Affiliated technical field
The present invention relates to a kind of lock gall, particularly a kind of annular keyhole lock container.
Background technology
The pellet shot from a slingshot of existing common its billiards structure of lock gall is distributed in always in the keyhole, and the robber is easier to open lock gall with master key, and the annular keyhole lock container that a kind of master key is difficult to open has become the needs that people improve the theftproof lock theftproof performance.
Summary of the invention
The present invention seeks to overcome the deficiencies in the prior art, a kind of annular keyhole lock container is provided, be used to improve the theftproof performance of theftproof lock.
The technical solution used in the present invention is: annular keyhole lock container, include lock body, lock core, billiard mechanism and key, and lock core is actively tied in the lock body, and lock core is provided with the ring key hole, and the centre in ring key hole is provided with anti-drill pin.There is a cylindrical hole in concrete mechanism in the middle of the lock core, be provided with anti-drill pin in the middle of the cylindrical hole; The ring key hole is made of the annular space between anti-drill pin and the cylindrical hole; The position of bottom, the ring key hole of lock core is provided with the shrinkage pool of unblanking, and is used to block key, makes the lock core can be with key turns.Annular keyhole lock container is supporting key, key is ring key or semi-circular key, ring key or semi-circular key are made of handgrip and pipe or semicircle pipe, pipe or the semicircle pipe external surface corresponding with billiard mechanism are provided with the pellet shot from a slingshot hole, the lower end of pipe or semicircle pipe is provided with the boss of unblanking, the shrinkage pool of unblanking that is used for lock core makes the lock core can be with key turns.
During use, ring key or semi-circular key are inserted in the ring key hole, the boss of unblanking of key pipe is inserted in the shrinkage pool of unblanking of position of ring key hole bottom of lock core, the interior pellet shot from a slingshot of billiard mechanism is inserted in the pellet shot from a slingshot hole of key correspondence, make the interface of outer pellet shot from a slingshot and interior pellet shot from a slingshot just in time be positioned at the contact position of lock body and lock core, this moment, outer pellet shot from a slingshot left the position of blocking the lock core rotation, key, lock core just can be opened theftproof lock along with key turns.
The invention has the beneficial effects as follows: because the keyhole of annular keyhole lock container is the structure with annular, there is anti-drill pin to separate between billiard mechanism left side pellet shot from a slingshot in the lock core and the right pellet shot from a slingshot and between preceding pellet shot from a slingshot and the back pellet shot from a slingshot, the robber is difficult to left pellet shot from a slingshot, right pellet shot from a slingshot or preceding pellet shot from a slingshot, back pellet shot from a slingshot in the master key while picking lock core ring key hole, increase the difficulty of opening lock gall, improved the theftproof performance of theftproof lock; Semi-circular key design is two, needs two semi-circular keys to open by a lock.
