Abstract
The utility model belongs to a lock cylinder class, in particular to an anti-theft lock cylinder, which comprises a lock cylinder, a lock sleeve and a locking segment and is characterized in that the opening of the lock cylinder is provided with a thickened sealing bolt pin and a sealing bolt pin spring, and the lock cylinder is provided with double rows of number bolt pins and a plurality of anti-shifting bolt pins to implement multidirectional locking. In the utility model, due to the fact that the opening of the lock cylinder is provided with the thickened sealing bolt pin, the arrangement conditions of the back bolt pins cannot be directly seen; simultaneously, the effective technical open space of a lockhole is reduced; when foreign matter is inserted into the lockhole, the sealing bolt pin is upwards shifted and the whole lock is jammed; because the sealing bolt pin is thickened and the strength is very high, forcible twist is unfeasible; moreover, the lock cylinder is provided with double rows of number bolt pins and the anti-shifting bolt pins to implement the multidirectional locking. Therefore, the lock can be opened only by the original key but is difficult to open by other tools. The lock cylinder has a very good anti-theft performance.
Description
Technical field
The utility model belongs to the lock core class, specifically is a kind of anti-theft lock.
Background technology
Used cylinder lock is easy to see pellet shot from a slingshot from lockhole at present, causes the lawless person with unlocking tool pellet shot from a slingshot to be chosen out easily, and lock is opened by force, and anti-theft feature is very poor.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of more reasonable structure, more reliable performance, the better anti-theft lock of anti-theft effect are provided.
The technical solution of the utility model is as follows:
A kind of anti-theft lock comprises lock core, lock tube, locking sheet, it is characterized in that: the lock core opening part has an overstriking to shut pellet shot from a slingshot and shuts marble spring.
Lock core of the present utility model has double number pellet shot from a slingshot and many anti-pellets shot from a slingshot of dialling, and realizes multidirectional locking.
The utility model is because the lock core opening part has an overstriking to shut pellet shot from a slingshot, can not directly see the arranging situation of back pellet shot from a slingshot, dwindle the effective technology of lockhole simultaneously and opened the space, when foreign matter inserts, overstriking is shut pellet shot from a slingshot and upwards one is moved, and whole lock is just stuck, and it is not all right turning round by force, because shut the pellet shot from a slingshot overstriking, intensity is very big; This lock core has double number pellet shot from a slingshot and many anti-pellets shot from a slingshot of dialling in addition, realizes multidirectional locking.Therefore have only original key better to open, other instruments are difficult to open, and theftproof performance is very good.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model sectional drawing.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of anti-theft lock comprises lock core 1, lock tube 2, locking sheet 4, it is characterized in that: the lock core opening part has an overstriking to shut pellet shot from a slingshot 3 and shuts marble spring 6.
Lock core 1 of the present utility model has double number pellet shot from a slingshot 7 and many anti-pellets shot from a slingshot 5 of dialling, and realizes multidirectional locking.
When the utility model is unblanked, original key is aimed at lockhole, key is inserted into the end after, the lock just opened.Because lock core 1 opening part has an overstriking to shut pellet shot from a slingshot 3, other instruments are difficult to open.
