Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment:

[0023] Referring to Figures 1-4 , an auxiliary fixing structure for the outer wall of a small distribution box, including a box body 1, a box door 2 is rotatably connected to a corner of one end inner wall of the box body 1, and an installation structure 7 is provided at the center of one side outer wall of the box body 1. A skeleton 13 is welded to the inner wall of the box body 1, and sliding grooves 14 are opened at both ends of the top inner wall and the bottom outer wall of the box body 1;

[0024] The installation structure 7 includes an installation bracket 8, insertion holes 9 opened at the centers of the outer walls of the four ends of the installation bracket 8, installation bolts 10 slidably connected in the insertion holes 9, and embedded grooves 11 opened at the four ends of one side outer wall of the installation bracket 8. After leveling the installation bracket 8, the expansion screws are fixed in the wall at the fixing holes 12, and the nut at one end of the expansion screw is located in the embedded groove 11 to prevent the screw from protruding.

[0025] A fixing hole 12 is opened at the center of the outer wall of the installation bracket 8 where the embedded groove 11 is located, and the insertion hole 9 is of a "convex" shape structure.

[0026] Bolt holes are opened on the outer walls of the box body 1 and the skeleton 13 at the positions of the insertion holes 9, and a nut is screwed on the outer wall of the installation bolt 10. One side outer wall of the nut is in contact with one side outer wall of the skeleton 13. The skeleton 13 on the inner wall of the box body 1 improves the overall strength. The installation bolt 10 is fixed in the skeleton 13 through the nut, ensuring the installation strength and avoiding deformation of the box body 1 during installation.
