One end of the spring 18 is connected to the main lock hook 15 or the auxiliary lock hook 16, and the other end is connected to the lock hook fixing bracket 17. When it is necessary to open the touch screen maintenance door 2, push the lock buckle operating handle 19 backward. The lock buckle operating handle 19 drives the main lock hook 15 to rotate downward with the lock hook connecting rod shaft 14 as the rotation center, and the heads of each lock hook rotate downward. The main lock hook 15 and the auxiliary lock hook 16 are disengaged from the lock hook rod 13, and the touch screen maintenance door 2 is opened by gravity. Release the lock buckle operating handle 19, and the spring resets, driving the main lock hook and the auxiliary lock hook to reset, preparing for the closing of the touch screen maintenance door 2. By placing the lock buckle operating handle 19 inside the cabinet body 1, it prevents the accidental opening of the touch screen maintenance door 2.

[0028] There is also a reinforcing rod 20 between the main lock hook 15 and the auxiliary lock hook 16. The reinforcing rod 20 is arranged parallel to the lock hook connecting rod shaft 14 above.

[0029] On the left and right sides of the touch screen maintenance door 2, there are symmetrically arranged limit rod assemblies 21. The limit rod assembly 21 includes a limit inner connecting rod and a limit outer connecting rod that are hinged to each other. The limit inner connecting rod is hinged to an inner connecting rod seat 22, and the inner connecting rod seat 22 is fixed on the cabinet body 1. The limit outer connecting rod is hinged to an outer connecting rod seat, and the outer connecting rod seat is fixed on the touch screen maintenance door 2. The inner connecting rod seat 22 is provided with a limit bump 22.1 corresponding to the limit inner connecting rod, and the limit bump controls the opening degree of the touch screen maintenance door 2. When the touch screen maintenance door 2 is turned down and opened forward, the touch screen maintenance door 2 suddenly drops due to gravity. The limit rod assembly 21 buffers the gravity of the touch screen maintenance door, balances the weight of the door, ensures that the touch screen maintenance door opens smoothly, avoids damage to the touch screen maintenance door caused by sudden dropping due to gravity, and at the same time, the limit bump locks the position of the touch screen maintenance door when it reaches the specified position, facilitating the installation and maintenance of equipment.

[0030] To prevent the limit rod assembly 21 from breaking and failing, resulting in the dropping of the touch screen maintenance door 2, an anti-drop chain 23 is also provided between the touch screen maintenance door 2 and the cabinet body 1. One end of the anti-drop chain is fixed to the inner top of the cabinet body 1 through a buckle, and the other end is arranged beside the lock hook rod 13 of the touch screen maintenance door 2.

[0031] A limit rod 24 is provided between the identity recognition device maintenance door 3 and the cabinet body 1. The limit rod 24 is in an L shape and avoids the hinge joint. One end of the limit rod 24 is fixed to the vertical hinge fixing bracket 5 through a limit rod bracket 25, and the other end is provided with a limit rod slider 26. The limit rod slider 26 is connected to a limit rod slide rail 27. The limit rod slide rail 27 is fixed to the bottom of the identity recognition device maintenance door 3. The limit rod slide rail 27 is provided with a chute corresponding to the limit rod slider 26, and one end of the chute is provided with a limit groove, and the limit groove communicates with the chute. The limit groove is close to the hinge joint between the identity recognition device maintenance door 3 and the cabinet body 1. When the identity recognition device maintenance door 3 is opened, the limit rod slider 26 at the end of the limit rod slides into the limit groove along the chute of the limit rod slide rail 27, and the opening degree of the identity recognition device maintenance door 3 is locked, facilitating the maintenance of the identity recognition device on the back of the maintenance door.

[0032] An anti-drop support 28 is provided at the bottom of the cabinet body 1. The identity recognition device maintenance door 3 is provided with rollers 29 corresponding to the anti-drop support 28. The rollers 29 are fixed to the limit rod slide rail 27 by roller brackets 30. The rollers 29 are arranged on the side away from the hinge to avoid the position of the limit rod 24. When the identity recognition device maintenance door 3 is closed for a long time, to avoid the maintenance door drooping due to gravity and mechanical fatigue, rollers are installed below the identity recognition device maintenance door. When the door is closed, the rollers move with the maintenance door and reach the top surface of the anti-drop support, playing a role in supporting the door, reducing the hinge load, greatly increasing the opening and closing times of the maintenance door, and extending the service life of the equipment.

[0033] The door lock 4 is connected to the linkage lock hook 31 through the unlocking connecting rod provided on the side. A lock rod 32 matching the linkage lock hook 31 is provided at the top inside the identification device maintenance door 3 to ensure that the identification device maintenance door 3 is firmly closed.

[0034] On the panel of the identification device maintenance door 3, corresponding to each identification device, it is divided into a palm vein recognition area 3.1, a two-dimensional code scanning area 3.2, an ID card scanning area 3.3, and a special certificate scanning area 3.4.

[0035] Double maintenance doors are arranged, one on the left and one on the right. While facilitating the placement of electrical equipment, it has a large maintenance operation space and is convenient for maintenance; the structure is simple and ingeniously designed. Only one door lock is set to realize the linkage opening of the identification device maintenance door and the touch screen maintenance door successively, and at the same time, the maintenance door in the open state is position-locked, improving the safety of maintenance. The lock handle for opening the touch screen maintenance door is built into the cabinet body to prevent accidental opening of the touch screen maintenance door, and the operation is safe and reliable.

[0036] In addition to the above embodiments, the present invention also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present invention.
