The second ventilation net 34 is fixedly connected to the lower side of the second mouse guard plate 33, and the second ventilation net 34 enables the second mouse guard plate 33 to have ventilation capabilities.

[0035] Working principle: After the base 2 is placed in the desired position, the staff first observes whether the base 2 is in a relatively horizontal state through the bubble level 41. When the base 2 is not in a relatively horizontal position, the staff only needs to rotate the corresponding adjustment ring 44 forward or reversely to make the corresponding adjustment ring 44 move up and down. During this process, the corresponding support sleeve 43 will move up and down together to adjust the base 2 horizontally. After the adjustment is completed, tighten the positioning screw 47 to fix the bearing support rod 46, and then the distribution cabinet body 1 can be placed on the ground. The first and second mouse guards 31 and 33 are placed in the bearing groove 22 inside the bottom base 2, and then the fixing screws 42 are tightened with the help of an external wrench, so that the fixing screws 42 fix the bottom of the power distribution cabinet body 1, thereby improving the stability of the power distribution cabinet body 1; then the staff respectively puts the first mouse guard 31 and the second mouse guard 33 against the left and right ends and the front and rear end surfaces of the bottom base 2. During this process, the extension screw 36 needs to be placed in the installation slot 37. At this time, the fixing nut 35 is fixed to the annular side of the extension screw 36, so that the fixing nut 35 fixes the first mouse guard 31 and the second mouse guard 33 (refer to Figure 1), so that the first mouse guard plate 31 and the second mouse guard plate 33 can block and protect external mice, and prevent external mice from drilling into the distribution cabinet body 1 through the through cavity 21 to damage the wires. At the same time, the first ventilation net 32 ​​and the second ventilation net 34 facilitate external air to pass through the first mouse guard plate 31 and the second mouse guard plate 33 to enter the bottom of the bottom base 2, so that the external air can pass through the through cavity 21 to enter the bottom of the distribution cabinet body 1 for ventilation and cooling. Later, the staff only needs to loosen and disassemble the fixing nut 35, and then they can disassemble and clean the first mouse guard plate 31 and the second mouse guard plate 33 respectively, and it is also convenient for the staff to rotate and adjust the adjustment ring 44 again.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
