[0031] Embodiment 3;

[0032] like Figure 1-7As shown, according to an embodiment of the present invention, a withdrawable power distribution cabinet includes a cabinet body 1, with several evenly distributed support blocks 2 provided at the bottom of the cabinet body 1, a cabinet door 3 provided on one side of the cabinet body 1, several evenly distributed mounting plates 4 provided in the cabinet body 1, guide blocks 5 provided on both sides of the mounting plates 4, a slide rod 6 provided in the cabinet body 1 that passes through the guide blocks 5, and a slide hole provided on the guide block 5 that matches the slide rod 6. A limit assembly matching the guide block 5 is provided on the inner wall of the cabinet body 1. A pull ring 15 is provided on one side of the mounting plate 4, and several evenly distributed circulation holes 16 are provided on the top of the mounting plate 4. The limiting assembly includes a fixed block 17 provided on the inner wall of the cabinet 1. A locking groove 18 matching the guide block 5 is defined on one side of the fixed block 17. A symmetrically arranged slide groove 19 is defined in the fixed block 17. A matching slider 20 is defined in the slide groove 19. The top of the slider 20 is connected to the fixed block 17 via a spring 21. A limiting ball 22 extending into the locking groove 18 is defined at the bottom of the slider 20. A limiting groove 23 matching the limiting ball 22 is defined on the guide block 5. The limiting ball 22 is in rolling connection with the slider 20. When it is necessary to inspect the electrical components inside the cabinet 1, the cabinet door 3 is opened and the pull ring 15 is pulled to cause the mounting plate 4 to be pulled outward. At this time, the guide blocks 5 on both sides of the mounting plate 4 squeeze the limit balls 22, and the limit balls 22 squeeze the springs 21 through the sliders 20. The springs 21 are compressed under the force, and the limit balls 22 disengage from the limit grooves 23 on the guide blocks 5 and enter the inside of the slide grooves 19. At this time, the guide blocks 5 are released from the limit and begin to slide on the slide rods 6 to drive the mounting plate 4 to move to the outside of the cabinet 1. By setting the slide rods, guide blocks and limit components, when personnel need to inspect the electrical components in the cabinet, the mounting plate can be pulled out, which is convenient for personnel to operate externally. After the inspection is completed, the mounting plate is pushed into the cabinet and fixed by the limit components, which is more flexible and convenient to use.

[0033] In actual application, when it is necessary to dissipate heat inside the cabinet 1, the exhaust fan 8 is started to discharge the heat inside the cabinet 1 through the exhaust holes 9. At the same time, the external air flows into the cabinet 1 through the air inlet holes 10, so that the air inside the cabinet 1 is in a circulation state, thereby accelerating its heat dissipation efficiency. When the inside of the cabinet 1 is humid, the electric heating wire 14 is started, and the exhaust fan 8 is started at the same time. When the external air flows into the cabinet 1 through the air inlet holes 10, the hot air generated by the electric heating wire 14 will flow inside the cabinet 1, thereby producing a drying effect. By setting up the exhaust box and the electric heating wire, the inside of the cabinet can be exhausted and cooled during normal use. When the inside of the cabinet is humid, it can be dried through the electric heating wire. When the electrical components inside the cabinet 1 need to be ventilated, the exhaust fan 8 is started. When performing maintenance, the cabinet door 3 is opened and the pull ring 15 is pulled to subject the mounting plate 4 to outward tension. At this time, the guide blocks 5 on both sides of the mounting plate 4 squeeze the limiting balls 22, and the limiting balls 22 squeeze the springs 21 through the sliders 20. The springs 21 are compressed under the force, and the limiting balls 22 disengage from the limiting grooves 23 on the guide blocks 5 and enter the inside of the slide grooves 19. At this time, the guide blocks 5 are released from the limit and begin to slide on the slide rods 6 to drive the mounting plate 4 to move to the outside of the cabinet 1. By setting the slide rods, guide blocks and limiting components, when personnel need to repair electrical components in the cabinet, the mounting plate can be pulled out, which is convenient for personnel to operate externally. After the maintenance is completed, the mounting plate is pushed into the cabinet and fixed by the limiting components, which is more flexible and convenient to use.

[0034] To sum up, with the help of the above-mentioned technical scheme of the present invention, by setting the sliding rod, guide block and limit assembly, when the personnel need to inspect the electrical components in the cabinet, the installation plate can be pulled out, which is convenient for the personnel to operate outside. After the inspection is completed, the installation plate is pushed into the interior of the cabinet and fixed by the limit assembly, which is more flexible and convenient to use. By setting the exhaust box and electric heating wire, the interior of the cabinet can be exhausted and dissipated during normal use. When the inside of the cabinet is humid, it can be dried by the electric heating wire.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
