[0037] Further, refer to Figure 1 , Figure 2 The box body 100 includes a middle member 110 and panels 120 on the upper and lower sides, that is, the box body 100 includes the middle member 110 and the panels 120 spliced together. Figure 3 The middle component 110 includes a rear side plate portion 111 and side plate portions 112 on the left and right sides. The rear side plate portion 111 , the side plate portion 112 and the panel 120 define a cavity of the box body 100 .
[0038] Further, refer to Figure 3 , reference Figure 6 The front side of the side panel portion 112 is bent to form a side panel edge guard 113, and the side panel edge guard 113 has a water retaining opening 130, and the water retaining opening 130 faces the outside of the box body 100. The water retaining opening 130 cooperates with the box door 200 to form a sealing structure for the front opening position of the box body 100. The design of this water retaining opening 130 can enhance the structural strength of the side panel portion 112 and even the front opening position of the box body 100. In addition, the water retaining opening 130 of the side panel edge guard 113 can be used as a water retaining and dust retaining groove, and cooperates with the box door 200 to achieve a better sealing and dustproof effect.
[0039] Further, refer to Figure 4, a spinning step 121 is provided at the edge of the panel 120, and the spinning step 121 is formed by spinning the edge of the panel 120 to form an inward structure.
