[0022] During use, by symmetrically arranging the two ventilation holes 4 on the outer walls on both sides of the distribution box body 1, the distribution box body 1 can be ventilated and cooled;

[0023] Magnetic adsorption frames 6 are adsorbed and installed on the outer walls of the distribution box body 1 below the ventilation holes 4, and dust-proof nets 7 are arranged inside the magnetic adsorption frames 6;

[0024] During use, through the arrangement of the dust-proof net 7, the ventilation holes 4 can be shielded from dust;

[0025] On the outer walls of both sides of the distribution box body 1 of the magnetic attraction frame 6, limit frames 5 are provided, and the inner walls of the limit frames 5 are in contact with the outer walls of the magnetic attraction frame 6;

[0026] During use, through the setting of the limit frame 5, the magnetic attraction frame 6 can be placed and processed;

[0027] A box door 2 is installed on the surface of the distribution box body 1 through a hinge. On one side of the surface of the box door 2, a door handle 202 is provided. On the surface of the box door 2 on one side of the door handle 202, a plurality of control buttons 201 are provided;

[0028] During use, through the setting of the door handle 202, the box door 2 can be opened and closed;

[0029] A box frame 13 is provided on the inner wall of the distribution box body 1. A temperature sensor 19 is installed on the inner wall of the distribution box body 1 above the box frame 13. Foot brake wheels 3 are installed at the corner positions at the bottom end of the distribution box body 1;

[0030] During use, through the setting of the temperature sensor 19, the temperature inside the distribution box body 1 can be monitored;

[0031] Three component placement cavities 14 are provided inside the box frame 13. Electrical components 15 are provided inside the component placement cavities 14. On both sides at the top end of the distribution box body 1, annular sealing plates 8 are installed. An annular frame 10 is fixed inside the annular sealing plates 8.
