Abstract
The utility model relates to a lock core structure of a cylinder lock, which comprises a lock core outer sleeve, a lock core, a cylinder and a lock core axle housing, wherein the lock core axle housing is installed in a lock core hole of the lock core outer sleeve, the lock core is arranged in the lock core axle housing, a coupling collar bush is arranged between the lock core and the lock core axle housing, and an unlocking jointing face and a returning locking jointing face are arranged on the lock core axle housing and matched with the coupling collar bush. The cylinder passes through the lock core and the coupling collar bush, the staggering positions of the opposite face of the lock core outer sleeve and the coupling collar bush are respectively provided with a groove, the corresponding part of the lock core axle housing is provided with an opening, and the groove and the opening are movably provided with rolling rods. The utility model overcomes the defects of poor anti-violent breakage performance and bad anti-theft performance of an ordinary lock core structure of a cylinder lock in the prior art; with the design, even though the lock core is destroyed violently, the rolling rod can perform the locking function so that the lock core can not rotate, and thus, the anti-theft performance is improved greatly. The utility model has the advantages of compact structure, flexible locking and unlocking of the lock core, strong anti-violent breakage performance, high safety coefficient and reliable use.
Description
Affiliated technical field
The utility model relates to a kind of cylinder of spring lock structure.
Background technology
In traditional cylinder lock lockset, its lock core is easy to be subjected to violence damage, as with the saturating lock core of bit drills; promptly do not have other any measures, lockset loses due protective effect, therefore; comparatively speaking, the anti-violence destructive characteristics of traditional cylinder of spring lock structure a little less than, theftproof performance is not good enough.
Summary of the invention
For overcome in the prior art the anti-violence destructive characteristics of common spring lock pin structure a little less than, the problem that theftproof performance is not good enough, the utility model provides a kind of cylinder of spring lock structure, and the compact conformation of this cylinder of spring lock structure, anti-violence destructive characteristics are strong, vi have high safety, use are reliable.
The technical scheme that its technical problem that solves the utility model adopts is: comprise lock core sleeve, lock core, pellet shot from a slingshot and lock core axle sleeve, lock core shaft is set in the lock core hole of lock core sleeve, in the lock core axle sleeve is lock core, the interlock ring set is set between lock core axle sleeve and lock core, lock core shaft puts and is provided with the unblank face that connects and the return locking that match with the interlock ring set and connects face, pellet shot from a slingshot passes lock core and interlock ring set, interleaved bits place at lock core sleeve and interlock ring set opposite face respectively is provided with a groove, corresponding of the lock core axle sleeve is provided with opening, and activity is provided with the rod that rolls in groove and the opening.
The utility model is by above-mentioned specific design, both made lock core suffer violence damage, the rolling rod can also play the locking safety effect, lock core can not rotate, strengthened theftproof performance greatly, had that compact conformation, lock core open and close flexibly, anti-violence destructive characteristics is strong, a vi have high safety, service-strong advantage.
