Description

Technical Field

[0001] The utility model belongs to the technical field of access control, in particular to an access control device for preventing fingerprint adhesion. Background Art

[0002] Access control refers to the prohibition of a door, which is a precaution against the door. The "door" here, in a broad sense, includes various passages that can be passed, including doors for people to pass through, doors for vehicles to pass through, etc. Therefore, access control includes vehicle access control. In parking lot management applications, vehicle access control is an important means of vehicle management, and fingerprint access control is a type of access control that uses fingerprints as the identification target.

[0003] For example, a computer room access control device with a publication number of CN220290252U is disclosed. The fingerprint access control prevents fingerprint adhesion by requiring the user to pick up a cleaning sponge to clean the fingerprint lock before use. This method is cumbersome to use, and if the cleaning sponge is lost, the fingerprint lock cannot be cleaned. In order to solve the above problem, an access control device that prevents fingerprint adhesion is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a door access control device for preventing fingerprint adhesion in order to solve the above problem.

[0005] The technical solution adopted by the utility model is as follows: a door control device for preventing fingerprint adhesion, comprising:

[0006] The access control body has a fingerprint chamber at the right end of the front side, a fingerprint lock is fixedly installed inside the fingerprint chamber, a liquid tank is fixedly installed at the upper end of the access control body, a water pipe is fixedly installed on the lower wall of the liquid tank, and a gear motor is rotatably connected to the side of the access control body close to the fingerprint chamber;

[0007] A sealing door, which is slidably connected to the upper wall of the fingerprint chamber, a rack is fixedly installed on the top of the sealing door, a connecting rod is fixedly installed on the outer wall of the lower end of the sealing door, a cleaning pad is fixedly installed on the end of the connecting rod, and the rack is meshed with the gear motor;

[0008] The electric spray head is fixedly mounted on the upper wall of the fingerprint chamber, and the upper end of the electric spray head is fixedly connected to the lower end of the water pipe.

[0009] Through the above technical solution, when the fingerprint lock needs to be used, the electric nozzle sprays the cleaning liquid in the liquid tank toward the fingerprint lock, and at the same time, the gear motor drives the rack to move upward, and the rack drives the sealing door to move upward to expose the fingerprint chamber. During the movement of the sealing door, it drives the connecting rod to move along its trajectory. At this time, the cleaning pad at the end of the connecting rod wipes the outer wall of the fingerprint lock, thereby effectively preventing fingerprint adhesion. The overall cleaning process does not require human assistance, which greatly improves the working efficiency of the equipment.

[0010] In a preferred embodiment, fixing seats are integrally provided on both left and right sides of the access control body.

[0011] Through the above technical solution, the access control body is installed on the wall through the fixing seat.

[0012] In a preferred embodiment, a pressure sensor is fixedly mounted on the outer wall of the front side of the access control body close to one end of the fingerprint chamber, and the pressure sensor is connected to the gear motor signal.

[0013] Through the above technical solution, when using the fingerprint lock, you need to press the pressure sensor first. After the pressure sensor receives the pressure signal, it makes the gear motor work. When not in use, the sealing door is closed to prevent dust from getting on the fingerprint lock.

[0014] In a preferred embodiment, a sealing cover is threadedly connected to the upper end of the liquid tank.

[0015] Through the above technical solution, the liquid tank is filled with liquid by opening the sealing cover.

[0016] In a preferred embodiment, a plurality of keyboards are provided on the front side of the access control body away from the fingerprint chamber.

[0017] Through the above technical solution, the access control system has both fingerprint and password unlocking functions.

[0018] In a preferred embodiment, the electric spray head is arranged at an angle, and its lower end faces the fingerprint lock.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: the utility model provides a door access control device that prevents fingerprint adhesion.

[0020] When the fingerprint lock needs to be used, the electric nozzle sprays the cleaning liquid in the liquid tank onto the fingerprint lock. At the same time, the gear motor drives the rack to move upward, and the rack drives the sealing door to move upward to expose the fingerprint chamber. During the movement of the sealing door, it drives the connecting rod to move along its trajectory. At this time, the cleaning pad at the end of the connecting rod wipes the outer wall of the fingerprint lock, thereby effectively preventing fingerprints from sticking. The overall cleaning process does not require human assistance, which greatly improves the working efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
