[0034] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0035] Example

[0036] An intelligent filing cabinet includes a cabinet body 1. The cabinet body 1 is internally divided into multiple compartments 2 by vertical and horizontal partitions. Each compartment 2 is hinged with an independent cabinet door 3. An RFID antenna module 4 is installed inside each compartment 2. A maintenance chamber 5 is opened between two rows of compartments 2. A maintenance door 6 is detachably installed in the maintenance chamber 5. A main control board 7, a temperature sensor 40, and a humidity sensor 41 are installed inside the maintenance chamber 5. One of the compartments is an electrical box 8. The door of the electrical box 8 is equipped with a display 9, a reader / writer 10, and a fingerprint lock 11, all of which are electrically connected to the main control board 7. An air power switch 12 and a power adapter 13 are installed inside the electrical box 8. The air power switch 12 and the power adapter 13 (100W) are electrically connected and connected to the main control board 7. A cable inlet 14 and a heat dissipation vent 15 are installed on the back of the electrical box 8.

[0037] Through the above technical solution, integrating the RFID antenna module 4, the intelligent filing cabinet can automatically identify and locate the RFID tags set on the files, realizing fast and accurate storage and retrieval of the files. The status of the files inside the filing cabinet is reflected on the display 9, allowing users to understand the status of the files inside the cabinet without opening the cabinet door. Users can authenticate their identity using a reader / writer 10 and a fingerprint lock 11, improving storage efficiency and security. The air power switch 12 and power adapter 13 installed inside the electrical box 8 ensure a stable power supply for the system, while heat dissipation is achieved through the heat dissipation holes 15, ensuring long-term stable operation of the system. The installation of the maintenance chamber 5 and maintenance door 6 makes system maintenance and troubleshooting more convenient. The temperature sensor 40 and humidity sensor 41 reflect the temperature and humidity inside the storage cabinet to the display via the main control board, making it convenient for staff to determine the suitability of the file storage conditions.

[0038] To achieve the emergency unlocking function of the filing cabinet, this embodiment adopts the following technical solution: a locking hook 16 is bolted to the inside of the cabinet door, and an electromagnetic lock 17 adapted to the locking hook 16 is installed in the maintenance cavity 5. The electromagnetic lock 17 has a locking tongue 19 that rotates along the first rotating shaft 18 and is adapted to the locking hook 16. One end of the locking tongue 19 abuts against a limiting member 21 that rotates along the second rotating shaft 20. An electromagnetic push rod 22 is connected to the end of the limiting member 21 away from the second rotating shaft 20 and the locking tongue 19. The electromagnetic lock 17 is also equipped with a micro switch 23, which abuts against the end of the locking tongue 19 away from the first rotating shaft 18 and the limiting member 21. A notch 24 is also provided on the outer periphery of the electromagnetic push rod 22. A positioning pin 25 is fixed to the electromagnetic lock 17, and a positioning hole 26 adapted to the positioning pin 25 is provided on the cabinet door 3. The micro switch 23 and the electromagnetic push rod 22 are electrically connected to the main control board 7. The maintenance cavity 5 is provided with a slide groove 42, and an emergency pull rod 43 is slidably connected to the slide groove 42. The emergency pull rod 43 is laterally provided with a stop rod 44 adapted to the notch of the electromagnetic lock.

[0039] Through the above technical solution, when the main control board 7 confirms that the corresponding cabinet door 3 is unlocked, it sends an unlocking signal to the corresponding electromagnetic lock 17. The electromagnetic push rod 22 retracts, pulling the limit piece 21 to rotate along the second rotating shaft 20, unlocking the lock tongue 19. The lock hook 16 pulls the lock tongue to rotate along the first rotating shaft to a suitable position to open the corresponding cabinet door. At this time, the lock tongue 19 presses the micro switch 23, keeping the main control board in the unlocked state with the electromagnetic push rod 22 retracted. When the cabinet door is closed, the lock hook 16 pushes the unlocked lock tongue back to its original position, and the lock tongue stops pressing the micro switch 23. The main control board adjusts the extension of the electromagnetic push rod 22 to achieve locking reset. In emergency situations such as power failure, the electromagnetic push rod 22 can be moved directly from the notch of the electromagnetic lock 17 after opening the maintenance door to achieve emergency unlocking. In necessary situations, such as when all the files in the filing cabinet need to be transferred or destroyed, pulling the emergency pull rod 43 causes the adjustment rod 44 to push the electromagnetic push rod 22 at each electromagnetic lock notch 24 to unlock all compartments 2.

[0040] To improve the security of the emergency unlocking function of the filing cabinet and to facilitate its installation and maintenance, this embodiment also adopts the following technical solution: A mechanical lock 27 is installed on the maintenance door 6. The mechanical lock 27 is rotatably connected to the middle of a limiting latch 28, which is a stepped plate. When the mechanical lock 27 is rotated open or closed, the two ends of the stepped plate correspondingly unlock or engage the cabinet body 1. A mounting tongue 29 is also provided at one end of the maintenance door 6, and a slot 30 for the mounting tongue 29 is provided on the cabinet body 1. Spherical anti-vibration washers 31 are also installed on the side of the maintenance door 6 and the cabinet door 3 that contacts the cabinet body 1.

[0041] Through the aforementioned technical solution, the linkage design of the mechanical lock 27 and the limit lock tongue 28 ensures the stable locking of the maintenance door 6 in non-emergency situations, preventing unauthorized access. One end of the maintenance door 6 is equipped with a mounting tongue 29, and the cabinet body 1 has a matching slot 30. This design simplifies the installation process of the filing cabinet, making the installation and disassembly of the maintenance door 6 more convenient, facilitating daily maintenance and troubleshooting. The use of anti-vibration washers 31 improves the overall structural stability and durability of the filing cabinet, ensuring reliability and stability during long-term use.

[0042] To ensure stable installation and aesthetically pleasing structure of the filing cabinet, the following technical solutions are also adopted in this embodiment: An adjusting plate 32 is installed at the hinge of the cabinet door. The adjusting plate 32 has a hinge hole and an elongated hole 33. An adjusting nut 34 is installed along the elongated hole 33. An adjusting bolt 35, compatible with the adjusting nut 34, is installed through the outside of the cabinet door 3. The bottom surface of the cabinet body 1 is also provided with a perforated mounting plate 36 with threaded holes. Threaded rods 38, compatible with the threaded holes, are installed on the support legs 37. The threaded rods 38 pass through the perforated mounting plate and are locked by two nuts.

[0043] Through the above technical solution, the adjusting plate 32 installed at the hinge of cabinet door 3, through the cooperation of adjusting nut 34 and adjusting bolt 35, can precisely adjust the gap between cabinet door and cabinet body 1, ensuring smooth opening and closing of cabinet door and improving installation accuracy and stability. The perforated mounting plate 36 on the bottom surface of cabinet body 1 cooperates with the threaded rod 38 of support leg 37, and the stability of filing cabinet is ensured by locking two nuts. The design of the threaded rod also allows for height adjustment of filing cabinet, maintaining stability even on uneven ground. Furthermore, an electromagnetic shielding layer 39 is provided between compartment 2 and RFID antenna module. Preferably, the inner wall of compartment is made of one of copper, aluminum, or steel, with a thickness of 3mm. It is sturdy and durable, ensuring the safety of filing cabinet, and its own electromagnetic shielding effect prevents RFID antenna module from misreading files in other compartments 2.

[0044] Working principle:

[0045] When installing the intelligent filing cabinet of this embodiment, the adjustment bolts of the adjusting plate are turned to fine-tune the cabinet door tilt, thereby ensuring the aesthetics of the cabinet door installation and its flatness with the cabinet body. The two bolts of the adjustable feet are used to control the height of the feet to adapt to uneven ground. When storing files, the electronic lock of the corresponding filing cabinet can be unlocked by sending a signal to the main control board through a fingerprint or reader to read the information card. The files stored in the compartments will have their relevant information read by the RFID antenna module, and the file number will be fed back to the main control board and displayed on the screen, so that staff can understand the location and status of the files without opening the cabinet door. In an emergency, the maintenance door can be opened to open the maintenance compartment, and the electromagnetic push rod at the notch of the electronic lock can be manually pushed to unlock the mechanical lock, or maintenance and repair work can be performed on the main control board.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
