Description

Dual open-type cylinder lock with self-destroying function

Technical field

The utility model belongs to the daily necessities field, relates to a kind of dual open-type cylinder lock with self-destroying function.

Background technology

At present, its lock core of cylinder lock of tradition use comprises: core shell, core body, lead sealing, spring, pellet shot from a slingshot group are formed.Arc surface between core shell and the core body is a unlatching face, the pellet shot from a slingshot group is passed unlatching face, core shell and core body become one and reach the purpose of pinning lock core, if the free cheek between two pellets shot from a slingshot overlaps with unlatching face, just can reach the purpose of opening lock core, make each pellet shot from a slingshot group all be in opening, the height of required key bit is well-determined.Owing to when production and processing, have error, make the pellet shot from a slingshot of each lock can not stop simultaneously that all core body rotates, and has produced the method that steel wire is unblanked.Even work in-process is error free in addition, also can between unlatching face, open a finedraw, the method unlocking spring lock that adopts clearance gauge to fill in.Chinese patent CN2309403Y discloses a kind of dual open-type cylinder lock, this cylinder lock has increased the secondary opening face owing to set up a movable pair core body in the lock housing of lock core, has only when two unlatching faces all are in opening, core body could freely rotate, and lock is opened.Though and the person that illegally do not unblank can touch the face of once unblanking with steel wire, can't open the secondary opening face, strengthened anti-theft capability.But because each the pellet shot from a slingshot group in the lock core is to pass two simultaneously to open face, lack the stuck self-destructor of pellet shot from a slingshot group locking, each pellet shot from a slingshot group can be moved up and down, so just give the person's opportunity of illegally not unblanking, cylinder lock just has the possibility that is unlocked.Therefore, there is unsafe factor in this cylinder lock, and its anti-theft feature still is limited.

Summary of the invention

The utility model has overcome the defective of above-mentioned existence, and purpose provides the high dual open-type cylinder lock with self-destroying function of a kind of antitheft unfailing performance.

The utlity model has the dual open-type cylinder lock content Description of self-destroying function:

The utlity model has the dual open-type cylinder lock of self-destroying function, by: core shell, core body, pair core body, hiding pellet shot from a slingshot group, last pellet shot from a slingshot, annular groove, spring, lead sealing, self-destruction pellet shot from a slingshot group, last pellet shot from a slingshot, pellet shot from a slingshot, groove, unlatching face, unlatching face, anti-drilling shell are formed, it is characterized in that: lock core is made up of core shell, core body, spring, lead sealing, pellet shot from a slingshot, form a unlatching face between core body and the core shell, in core body, be provided with one and can rotate and axially movable pair of core body, and form another unlatching face between the core body; Pellet shot from a slingshot and pellet shot from a slingshot are formed on the hollow cup-shaped pellet shot from a slingshot group, spring, lead sealing are installed in the core body, and the pellet shot from a slingshot group that pellet shot from a slingshot and pellet shot from a slingshot are formed on the hollow cup-shaped is passed to pay and formed unlatching face between core body and the core body; In the core shell, install and hide pellet shot from a slingshot group, spring, lead sealing, and pass the unlatching face that forms between core shell and the core body by hiding pellet shot from a slingshot group, on the periphery of paying core body, have simultaneously one vertically and be used to accept the groove of hiding the pellet shot from a slingshot group, in the core shell, be positioned at a side of hiding the pellet shot from a slingshot group and be equipped with and hide self-destruction pellet shot from a slingshot group that the pellet shot from a slingshot group blocks and spring and the lead sealing that matches with self-destruction pellet shot from a slingshot group; The outer setting anti-rotation shell of core shell, and expose unlatching face.Wherein going up pellet shot from a slingshot is hollow cup-shaped pellet shot from a slingshot, and its hollow cup-like portion matches with spring, can minification, reduce volume, and save material.

The utlity model has the dual open-type cylinder lock of self-destroying function, because two unlatching faces are to be passed respectively by pellet shot from a slingshot group separately, wherein a pellet shot from a slingshot group is in hidden state, and installs and can will hide the self-destruction pellet shot from a slingshot group that the pellet shot from a slingshot group is blocked in its side.Therefore, the person that illegally do not unblank promptly uses unlocking tool can open the first unlatching face, but can not open the second unlatching face, and causes the cylinder lock self-destruction, has the safe and reliable characteristics of cylinder lock performance.
