Description

Fingerprint door lock with lockhole protective cover

Technical Field

The utility model belongs to the technical field of the fingerprint lock, concretely relates to fingerprint lock with lockhole protective cover.

Background

The fingerprint lock is an intelligent lock, and is a perfect crystal of computer information technology, electronic technology, mechanical technology and modern Wujin technology. The characteristics of fingerprints become the most important evidence for identity identification and are widely applied to the fields of public security criminal investigation and judicial law. The fingerprint authentication has the characteristics of convenience, rapidness, accuracy and the like. With the popularization of science and technology and the development of smart homes, more and more people also start to select fingerprint locks.

The action of spring bolt in the fingerprint lock is by built-in motor drive, when fingerprint module discerned correct fingerprint information promptly through PCB control motor start-up, accomplishes the action of unblanking. When the fingerprint lock loses the power, or fingerprint module, internal circuit go wrong, the unable normal start-up of motor, then the lock can't be opened. In order to prevent this, a conventional lock hole is usually formed in the lock cylinder of the fingerprint lock, and the lock can be unlocked when a key is inserted into the lock hole, such as by power loss or circuit failure. However, most of the keyholes on the existing fingerprint locks are exposed, the keyholes are not used under the common condition, and fine sundries can enter or be maliciously inserted by people or damp in the keyholes due to long-term exposure, so that the keys cannot be in perfect butt joint with the keyholes during use.

Disclosure of Invention

The utility model aims at providing a structure sets up reasonable and suitability strong fingerprint lock with lockhole protective cover.

The technical scheme for realizing the purpose of the utility model is that the fingerprint door lock with the lockhole protective cover comprises a front lock body, a lock core is arranged in the front lock body, one end of the lock core is inserted into the front lock body, a fingerprint operation hole and a lockhole are arranged on the front lock body, a cavity is arranged in the front lock body, the cavity is arranged under the lockhole, a lockhole protective cover is arranged in the cavity, a reset tension spring is fixed between the top of the lockhole protective cover and the bottom wall of the cavity, a button hole is fixed in the front lock body, the button hole is arranged right above the lockhole, a press rod is arranged in the button hole, an interlock magnet is fixed at the inner side end of the press rod, an attraction magnet is fixed at the bottom end of the lockhole protective cover, the lockhole protective cover is connected and fixed with the attraction magnet through the interlock magnet and seals the lockhole when the cover is closed, when the pressing rod is pressed inwards, the occlusion magnet is separated from the attraction magnet, and the lock hole protective cover is reset downwards under the action of the reset tension spring to expose the lock hole.

And a return spring is fixed between the occlusion magnet and the end wall of the cavity, and the pressing rod is reset through the return spring when external force disappears after being pressed downwards.

And the edge of the lock hole protective cover is wrapped with a sealing rubber strip.

And a manual operation protrusion is fixed on the top of the outer wall of the lock hole protective cover.

The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, the simple operation, it not only can be effectively and quick realization be favorable to avoiding the lockhole to wet or block up to the sealing of lockhole, has guaranteed to use reliable and stable nature, and the suitability is strong and the practicality is good.
