[0029] Example 2

[0030] refer to Figures 2 to 4 Example 2 is described. This embodiment further describes Example 1 and includes a threaded block. The threaded block 19 is slidably connected to the slide rod 18. A first movable rod 20 is installed at the bottom end of the threaded block 19, and a second movable rod 22 is provided on one side of the first movable rod 20. The first movable rod 20 and the second movable rod 22 are rotatably connected by a rotating shaft 21. The second movable rod 22 is rotatably connected to a U-shaped frame 23 through the rotating shaft 21, and the U-shaped frame 23 is fixedly installed on the side wall of the bottom end of the cabinet 1. The bottom ends of the first movable rod 20 and the second movable rod 22 are connected to a connecting frame 24, and a universal wheel 25 is installed at the bottom end of the connecting frame 24. A bottom opening 26 is provided at the bottom end of the cabinet body 1. The diameter of the bottom opening 26 is larger than the size of the universal wheel 25. Two first bevel gears 10 are fixedly installed on the rotating rod 9 at the output end of the drive motor 8. The two first bevel gears 10 are meshed with a second bevel gear 11. A first threaded rod 12 is fixedly installed in the middle of the second bevel gear 11. A threaded sleeve 13 is threadedly connected to the first threaded rod 12. Slots 4 are provided on both sides of the support column 3. A connecting block 14 is fixedly installed on the threaded sleeve 13, and the other side of the connecting block 14 passes through the slot 4 and is fixedly installed with a cabinet door 5. A sealing ring 15 is installed between the cabinet door 5 and the cabinet body 1;

[0031] In this embodiment, the provided moving component can realize the extension and retraction of the universal wheel 25, which facilitates the movement and fixation of the cabinet body 1. The provided lifting component can drive the motor 8 to drive the rotating rod 9 to rotate, and through the transmission of the first bevel gear 10 and the second bevel gear 11, the first threaded rod 12 is rotated, and then the threaded sleeve 13 is moved to realize the lifting and lowering of the cabinet door 5.

[0032] In specific applications, when the cabinet 1 needs to be moved, the operator controls the dual-axis motor 16 through the panel 6 to start. The dual-axis motor 16 drives the second threaded rods 17 on both sides to rotate. Since the threaded block 19 is threadedly connected to the second threaded rod 17, the threaded block 19 will move along the second threaded rod 17. As the threaded block 19 moves, the angles of the first movable rod 20 and the second movable rod 22 change, driving the connecting frame 24 to move downward, causing the universal wheel 25 to extend from the opening at the bottom of the cabinet 1 and contact the ground, thereby easily pushing the cabinet 1 to move to the desired position. When the cabinet 1 is moved into place, the dual-axis motor 16 is started again to retract the universal wheel 25, and the cabinet 1 is placed stably. The operator controls the drive motor 8 through the panel 6 to start. The drive motor 8 drives the rotating rod 9 to rotate, and the first bevel gear 10 on the rotating rod 9 rotates accordingly. The first bevel gear 10 engages with the second bevel gear 11, transmitting power to the second bevel gear 11, causing the first threaded rod 12 in the middle of the second bevel gear 11 to rotate. Because the threaded sleeve 13 is threadedly connected to the first threaded rod 12, the sleeve 13 moves along the first threaded rod 12, driving the cabinet door 5 up and down via the connecting block 14, thereby opening and closing the cabinet door 5. The fan 28 and the moisture-absorbing plate 30 work together to maintain a suitable environment within the cabinet 1. When the fan 28 is activated, it accelerates the flow of air within the cabinet 1, dissipating heat through the heat dissipation holes 7 and the heat dissipation pipe 29, thereby lowering the temperature within the cabinet 1. The moisture-absorbing plate 30 continuously absorbs moisture within the cabinet 1 to prevent damage to components. The main control chip 32 monitors the voltage in real time via the voltage sensor 34, taking timely action when the voltage is abnormal. The overload protector 35 automatically disconnects the circuit in the event of an overload, protecting the device. The wireless connection module 37 enables communication between the device and external systems, facilitating remote monitoring and control. Components such as the capacitor 36, the isolating switch 38, and the grounding switch 39 perform their respective functions within the circuit to ensure normal operation.
