Abstract

The utility model relates to an anti-theft lock cylinder, which solves the problems that the conventional lock cylinder adopts an integral structure and has poor anti-theft performance. The anti-theft lock cylinder consists of a first lock cylinder and a second lock cylinder, wherein the rear end of the first lock cylinder is in contact connection with the front end of the second lock cylinder; cross key holes are formed in the middles of the first and the second lock cylinders in a front-back corresponding manner; four rows of pin tumbler holes are uniformly distributed on the outer wall of the first lock cylinder as well as that of the second lock cylinder in the length direction; each row includes 3 to 5 pin tumbler holes; and the four rows of pin tumbler holes and the cross key holes are in one-to-one correspondence and mutually communicated. As the split-type lock cylinder is adopted, unlocking can not be conducted when no key is available, so that the anti-theft performance is greatly improved.

Description

Anti-theft lock

Technical field

The utility model relates to a kind of lock core.

Background technology

Existing lock core is all as a whole, and the professional who unblanks just can open under the situation of key not having, and theftproof is poor.

Summary of the invention

The purpose of this utility model is all as a whole in order to solve existing lock core, the problem of theftproof difference, and then a kind of anti-theft lock is provided.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: anti-theft lock of the present utility model is made up of first lock core and second lock core, the rear end of described first lock core is connected with the preceding end in contact of second lock core, correspondence has the cross keyhole before and after the middle part of described first lock core and second lock core, the uniform along its length four row's pellet shot from a slingshot holes that have on the outer wall of described first lock core and second lock core, the quantity in every row's pellet shot from a slingshot hole is three～five, and four row pellet shot from a slingshot holes are corresponding one by one with the cross keyhole and be interconnected.

The beneficial effects of the utility model are: anti-theft lock of the present utility model is provided with split type lock core, can only open first lock core 1 the professional who does not have to unblank under the situation of key, and can't open second lock core 2, therefore lock can't be opened, really played anti-theft feature, especially can be applied on the lockset of safety cabinet.

Description of drawings

Fig. 1 is the front view of anti-theft lock of the present utility model, and Fig. 2 is the vertical view of Fig. 1, and Fig. 3 is the vertical view cutaway drawing of Fig. 2, and Fig. 4 is the schematic diagram of first lock core, and Fig. 5 is the schematic diagram of second lock core.

The specific embodiment

The specific embodiment one: shown in Fig. 1～5, the described anti-theft lock of present embodiment is made up of first lock core 1 and second lock core 2, the rear end of described first lock core 1 is connected with the preceding end in contact of second lock core 2, correspondence has cross keyhole 3 before and after the middle part of described first lock core 1 and second lock core 2, the uniform along its length four row's pellet shot from a slingshot holes 4 that have on the outer wall of described first lock core 1 and second lock core 2, the quantity in every row's pellet shot from a slingshot hole 4 is three～five, and four row pellet shot from a slingshot holes 4 are corresponding one by one with cross keyhole 3 and be interconnected.

During use, be installed in first lock core 1 and second lock core 2 in the lock tube successively, pellet shot from a slingshot is installed in each pellet shot from a slingshot hole 4 of first lock core 1, second lock core 2 then, the professional who unblanks is not having under the situation of key, can only open first lock core 1, and can't open second lock core 2, and therefore lock can't be opened, really played anti-theft feature.

The specific embodiment two: shown in Fig. 2,3 and 5, the outside of described second lock core 2 of present embodiment along the circumferential direction has annular groove 2-1.So design can prevent that second lock core 2 from dropping out in lock tube.Other composition and annexation are identical with the specific embodiment one.

The specific embodiment three: shown in Fig. 2 and 3, the quantity in the described every row's pellet shot from a slingshot of present embodiment hole 4 is 4, and the quantity in the every row's pellet shot from a slingshot hole 4 on first lock core 1 and second lock core 2 is two.Other composition and annexation are identical with the specific embodiment one or two.
