A plurality of positioning holes e22221 for positioning and mounting on the second side plate assembly 4 are formed on the sixth connecting surface 2222.

[0064] The third bending piece 223 comprises a ninth connecting surface 2231, a tenth connecting surface 2232, an eleventh connecting surface 2233 and a twelfth connecting surface 2234. The ninth connecting surface 2231 and the eleventh connecting surface 2233 are vertically arranged, and the ninth connecting surface 2231 is located outside the eleventh connecting surface 2233.

[0065] In the present application, the mounting position of the fastener for connecting the first metal edge 211 and the upper surface of the top plate 21 is staggered with the mounting position of the fastener for connecting the first bending piece 221 and the lower surface of the top plate 21; the mounting position of the fastener for connecting the second metal edge 212 and the upper surface of the top plate 21 is staggered with the mounting position of the fastener for connecting the second bending piece 222 and the lower surface of the top plate 21; the mounting position of the fastener for connecting the third metal edge 213 and the upper surface of the top plate 21 is staggered with the mounting position of the fastener for connecting the third bending piece 223 and the lower surface of the top plate 21. In this way, the sealing performance of the box body can be further enhanced, and external rainwater and saltwater can be prevented from penetrating into the box body through the fasteners on the upper surface of the top plate 21. Of course, glue or the like can also be applied at the mounting position of the fastener to further enhance the sealing performance of the box body.
