A security fingerprint lock for community access control

Abstract

The invention discloses a security protection fingerprint lock for entrance guard of a residential district. The security protection fingerprint lock for the entrance guard of the residential district structurally comprises a protective box, an outer password lock body and a fingerprint lock body. The fingerprint lock body is arranged inside the protective box. Soft layers are arranged on the inner wall of the protective box and located on the two sides of the fingerprint lock body. The obverse end face of the protective box is matched with a drawing and pulling layer in the outer password lock body in a clearance fit mode, and the interior of the drawing and pulling layer is filled with an expansive sponge body. The end, making contact with the protective box, of the outer password lock body is matched through a drawing and pulling groove. Air suction mechanisms which are matched with the soft layers are arranged in the protective box. According to the security protection fingerprint lock for the entrance guard of the residential district, the protective box can protect the fingerprint lock body from being damaged by the external force; and the soft layers and the air suction mechanisms arranged inside the protective box cooperate with each other, the moisture inside the protective box is sucked away under the action of air suction of air suction machines through the soft layers on the two sides and is finally centralized in rubber bowls, drying operation is conducted by drying agents in the rubber bowls, and therefore the humidity inside the protective box is reduced, the fingerprint lock body can be kept enough dry all the time no matter when the lock is affected by any weather, and fingerprint recognition cannot be affected.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a security fingerprint lock used for community access control. Background technique [0002] Fingerprint locks are high-tech security products, which are more and more popular among people. There are various locks in the existing technology.

[0002] Fingerprint locks are high-tech security products, which are more and more popular among people. There are various locks in the existing technology. The fingerprint locks used in some communities are equipped with double protection. The first protection is mainly It is to ensure that the fingerprint identification area of ​​the fingerprint lock will not be affected by children or external dirt, but it is also the first layer of protection that is generally a movable closed box. After the summer rainy day, the internal temperature of the closed box is higher than the external temperature. Severe internal fogging leads to a layer of water mist in the fingerprint identification area. Because the water mist accumulates on the fingerprint identification area and causes the area to be wet, it is difficult to identify during fingerprint identification.
