Description

Technical Field

[0001] The utility model relates to the technical field of intelligent door locks, in particular to a key protection device for an intelligent door lock. Background Art

[0002] Smart door locks are composite locks that are different from traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and manageability. They are the executive components of locking doors in access control systems. Common smart door locks include magnetic card locks, fingerprint locks, iris recognition locks, etc., which are mostly used in banks, government departments (focusing on security), hotels, etc.

[0003] A key protection device for a smart door lock with publication number CN217538225U includes a door lock body, a key body and a protective baffle. The key body is arranged on the front of the door lock body near the top, and the left and right sides of the door lock body are fixedly connected with guide rails, and the position of the guide rails corresponds to the key body. The front of the door lock body is slidably connected with a protective baffle. The key protection device for a smart door lock has a protective baffle slidably installed on the front end of the door lock body, and then cooperates to support the protective baffle so that the protective baffle cooperates with the door lock body to completely cover the key body, effectively isolating the key body from the outside world and preventing the key body from being contaminated with dust. At the same time, the surface of the key body is wiped with a cleaning cloth to prevent fingerprints from remaining on the surface of the key body, thereby ensuring the security of the password and reducing existing safety hazards. In addition, the existing protective device also has the following disadvantages during use:

[0004] (1) The cleaning cloth of the existing protective device is not easy to disassemble. The cleaning cloth is connected to the protective baffle through the structure of the back plate, the pin and the socket. When removing the cleaning cloth, since the back plate and the protective baffle are fixedly connected with the spring, it is not convenient to pull out the pin from the socket and then remove the cleaning cloth from the back plate. Such a disassembly process is relatively cumbersome and disassembly becomes more difficult. Utility Model Content
