Description
Technical field
The utility model is related to a kind of lockset, specifically a kind of fingerprint-based padlock.
Background technology
Padlock, is most ancient, most huge family in the lockset world, it may be said that other locksets are all from padlock this class
Procreation, derive from and come.On the lock body of padlock equipped with can with the U-shape lock ring of snapping, make padlock by U-shape lock ring directly and lock body
Snapping turns into enclosed shape lockset.
Due to the design feature of padlock, padlock easy to use and flexible is determined, it is widely used.It can replace other locksets,
And other locksets can not play a role instead of padlock, it be it is a kind of it is more satisfactory prevent dead lock,
Traditional padlock is mainly billiards structure class padlock, and such lockset sets barrier with cylindrical type pellet in lock core
Hinder, so that lock core can not be rotated, reach the effect of locking.Billiards structure is also one of conventional structure of lockset.
With the raising of modern life technical merit, traditional padlocks are leaving behind key or key falls using more inconvenient
When, then can not open padlock, it is too many additionally, due to various enabling keys, with a lot keys with it is also inconvenient, it is traditional
Padlock anti-theft capability is also poor, the necessary safe antitheft performance for further enhancing padlock.
Utility model content
The purpose of this utility model is to provide a kind of fingerprint-based padlock, sets fingerprint to open work(on the basis of traditional padlocks
Can, further enhance the convenience and safe antitheft performance of padlock.
In order to achieve the above object, the utility model is adopted the following technical scheme that, a kind of fingerprint-based padlock, including lock body, should
Lock ring is provided with lock body, its key is：Wedge mouthful is provided with the left and right ends of lock ring, is equipped with two wedges mouthful
Two latches, the outer end of two latches coordinates for wedge shape with two wedges mouthful, and inner abut of two latches has drive shaft, two
