[0023] During use, the components inside the cabinet 2 are installed on the mounting plate 7. When the cabinet door 1 is in a closed state, the squeezing ball 6 is located inside the mounting groove 3 and squeezes the pressure sensor 5, so that the pressure sensor 5 detects pressure. At this time, the spring 4 is in an squeezed state. When the staff opens the cabinet door 1, the squeezing ball 6 is moved away from the inside of the mounting groove 3, so that the squeezing ball 6 no longer squeezes the pressure sensor 5. At the same time, the pressure sensor 5 is reset by the spring 4. When the pressure sensor 5 does not detect pressure, the information is transmitted to the PLC controller, and the drive motor 11 is started to rotate the screw rod 9, and then the mounting plate 7 is moved to the front side, so that the components on the mounting plate 7 are moved to the outside of the cabinet 2, and then the staff performs maintenance; conversely, when the cabinet door 1 needs to be closed after maintenance, the drive motor 11 is started first to rotate the screw rod 9, and the mounting plate 7 and the components are moved to the rear side until the mounting plate 7 and the components are completely located inside the cabinet 2, and then the cabinet door 1 is closed. When the staff opens the cabinet door 1, the installation plate 7 and the components can be automatically moved outside the cabinet body 2, which helps to improve the availability and convenience of the operating space, thereby helping to reduce the difficulty and time consumption of the work.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a plurality of heat dissipation holes 12 are provided on the top surface of the cabinet 2, an air inlet 13 is provided on the left side of the outer wall of the cabinet 2, a fan 14 is fixed inside the air inlet 13, and the fan 14 is electrically connected to the PLC controller.

[0025] During use, the heat dissipation holes 12 and the fan 14 facilitate blowing external air into the interior of the cabinet 2, thereby promoting air flow, effectively dissipating heat, and helping to reduce the internal temperature, thereby improving the working efficiency and life of the equipment.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a fixing hole 15 is opened on the top surface of the cabinet 2, and a temperature sensor 16 is fixed to the inner wall of the fixing hole 15. The temperature sensor 16 is electrically connected to the PLC controller. A mounting frame 17 is fixed to the left side of the outer wall of the cabinet 2, and a dustproof net 18 is fixed to the inner wall of the mounting frame 17. The dustproof net 18 blocks the outer end of the fan 14.

[0027] In use, the temperature sensor 16 is used to monitor the temperature change inside the cabinet 2 in real time. When the temperature exceeds the set threshold, the information is transmitted to the PLC controller to start the fan 14, which is conducive to timely lowering the temperature and protecting the equipment from overheating damage. The dustproof net 18 is used to prevent dust, fine particles and other debris from entering the cabinet 2, reducing the occurrence of equipment failures and extending the service life of the equipment.

[0028] like Figure 1-Figure 4 As shown, the left and right sides of the inner wall of the cabinet body 2 are respectively provided with slide grooves 19, and the left and right sides of the outer wall of the mounting plate 7 are respectively fixed with sliding rods 20, and the two sliding rods 20 are respectively slidably arranged in the two slide grooves 19, and an observation hole 21 is opened on the front side of the outer wall of the cabinet door 1, and a transparent glass 22 is fixed to the inner wall of the observation hole 21.

[0029] In use, the slide groove 19 and the sliding rod 20 are used to limit the mounting plate 7 and prevent the mounting plate 7 from shifting, thereby improving the stability of the mounting plate 7 when moving. The observation hole 21 and the transparent glass 22 allow the staff to easily observe the working state and equipment operation inside the cabinet 2, which helps to find abnormalities or faults in time.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
