Description

A kind of anti-theft spring lock core

Affiliated technical field:

The utility model relates to the lock core in the lockset, especially a kind of anti-theft spring lock core.

Background technology:

In the prior art, known lock cylinder all is to be surrounded by a rotating lock core in the lock core cover, and keyhole is arranged in lock core, and lock core and lock core have put the pellet shot from a slingshot passage, following pellet shot from a slingshot is arranged in the pellet shot from a slingshot passage, go up pellet shot from a slingshot and spring.What this lock cylinder was as easy as rolling off a log just can be by pirate of the open, as long as use lockaid gun just can open it easily, so its antitheft poor ability, this is the main weak point of existing in prior technology.

Summary of the invention:

The utility model is at the existing in prior technology deficiency, and a kind of anti-theft spring lock core technical scheme is provided.

This programme is realized by following technical measures: mainly include the lock core in lock core cover and the lock core cover, keyhole is arranged in lock core, the pellet shot from a slingshot passage is arranged on lock core, in the pellet shot from a slingshot passage spring is arranged, last pellet shot from a slingshot and following pellet shot from a slingshot, in addition, the shifting block of unblanking in addition, the characteristics of this programme are that described lock core includes the twist lock core, fixed lock core and outer twist lock core, the twist lock in-core has keyhole, the twist lock core is surrounded by fixed lock core outward, the rear end of twist lock core is inserted into a barrel-shaped outer twist lock in-core chamber, outer twist lock in-core has the keyhole that communicates with lock core keyhole, outside fixed lock core and outer twist lock core the lock core cover is arranged, and can rotate between twist lock core and the fixed lock core, fixing can not the rotation between fixed lock core and the lock core cover, all rotatable between outer twist lock core and twist lock core and the lock core cover; Twist lock core pellet shot from a slingshot passage is arranged on twist lock core and fixed lock core, on twist lock core and outer twist lock core, outer lock core pellet shot from a slingshot passage is arranged, put outer twist lock core pellet shot from a slingshot passage at outer twist lock core and lock core, in the inside and outside lock core marble passage of twist lock core pellet shot from a slingshot passage and in the outer twist lock core pellet shot from a slingshot passage, all be equipped with down pellet shot from a slingshot, on pellet shot from a slingshot and spring.The concrete characteristics of this programme also have, and described twist lock core pellet shot from a slingshot passage has 3 at least.Described outer lock core pellet shot from a slingshot passage has 1-4.Described outer twist lock core pellet shot from a slingshot passage has 1-4.The described shifting block of unblanking is on the end face of outer twist lock core.

The beneficial effect of this programme can be learnt according to the narration to such scheme, because the lock core in this scheme includes the twist lock core, fixed lock core and outer twist lock core, the twist lock in-core has keyhole, the twist lock core is surrounded by fixed lock core outward, the rear end of twist lock core is inserted into a barrel-shaped outer twist lock in-core chamber, outer twist lock in-core has the keyhole that communicates with lock core keyhole, outside fixed lock core and outer twist lock core, the lock core cover is arranged, can rotate between twist lock core and the fixed lock core, fixing can not the rotation between fixed lock core and the lock core cover, all rotatable between outer twist lock core and twist lock core and the lock core cover; Twist lock core pellet shot from a slingshot passage is arranged on twist lock core and fixed lock core, on twist lock core and outer twist lock core, outer lock core pellet shot from a slingshot passage is arranged, put outer twist lock core pellet shot from a slingshot passage at outer twist lock core and lock core, in each pellet shot from a slingshot passage, all be equipped with down pellet shot from a slingshot, on pellet shot from a slingshot and spring.This structure, when twist lock core and outer twist lock in-core do not insert key, last pellet shot from a slingshot in each pellet shot from a slingshot passage will be between twist lock core and fixed lock core, twist lock core and outer twist lock core and outer twist lock core and the lock core cover, twist lock core and outer twist lock core can not be rotated, unblank so the shifting block of unblanking can not rotate; When twist lock core and outer twist lock in-core insertion key, last pellet shot from a slingshot in each pellet shot from a slingshot passage and following pellet shot from a slingshot junction, will be between twist lock core and fixed lock core, twist lock core and outer twist lock core and outer twist lock core and the lock core cover, twist lock core and outer twist lock core can be rotated, shifting block also can rotate and unblank so unblank, and is phase-locked together with common spring.But, when twist lock core and outer twist lock in-core do not insert key, it is just quite difficult to want to unblank, because twist lock core and outer twist lock core are splits, between has the slit, and the way of locking with pirate of the open can make the twist lock core rotate, and outer twist lock core is rotated simultaneously, so can not open lock, use professional lockaid gun also powerless.With the entity sample lock of this programme lock core, the personnel of the company of please professional unblanking unblank, and nobody can open the sample lock, so the anti-theft capability of provable this programme lock core is extremely strong.This programme applicable with single face, two-sided, various keys such as three or cruciate flower, therefore, twist lock core pellet shot from a slingshot passage will have 3 at least, outer lock core pellet shot from a slingshot passage will have 1-4, outer twist lock core pellet shot from a slingshot passage will have 1-4, to adapt to multi-form key.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
