Description

Technical Field

[0001] The utility model relates to the technical field of access control locks, in particular to an intelligent access control lock with cleanable fingerprints. Background Art

[0002] With the development of technology, in order to improve the convenience of opening the door, many users will install access control locks, so that they do not need to carry keys during use, and can open the door with fingerprints and passwords. Compared with the previous mechanical locks, it is more secure and more convenient to use;

[0003] In actual use, existing access control locks often open the door in two ways: one is fingerprint unlocking, and the other is password unlocking. Fingerprint unlocking often leaves fingerprints on the fingerprint reader, so some unscrupulous elements can configure the corresponding fingerprint set according to the left fingerprint, and then open the door to carry out illegal actions, thus affecting the security of the access control lock. Therefore, we propose a smart access control lock with cleanable fingerprints. Utility Model Content

[0014] By adopting the above technical solution and the arrangement of the convex strip, when the movable plate is disassembled, the convex strip can be directly pulled, thereby driving the movable plate to move, making it easier to exert force and further improving the convenience of disassembly.

[0015] As a preferred embodiment of the present utility model, an infrared switch is fixed to the inner wall of the handle.

[0016] By adopting the above technical solution, the infrared switch and the lead screw motor are electrically connected, so that the lead screw motor can be automatically started when the handle is grasped, thereby driving the cleaning frame to move, and automatically moving the cleaning frame back and forth, thereby improving the convenience of operation.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The technical solution of the present application is a fingerprint cleanable smart access control lock, which can use the lead screw motor to drive the lead screw to rotate after the fingerprint is identified by the fingerprint identifier, so as to drive the lead screw slider to move, thereby driving the cleaning frame to move, and use the cleaning cotton pad on the inner wall of the cleaning frame to wipe the fingerprint identifier, so as to clean the residual fingerprint traces, thereby preventing criminals from using the residual fingerprint traces to commit illegal acts;
