The second connecting rib is connected between the side plate body 131 of the first side plate 13a and the side plate body 131 of the second side plate 13b, and is used for improving the connection strength between the first side plate 13a and the second side plate 13 b. In the related art, the positioning structure is lacking among the bottom plate 11, the panel 12 and the side plate 13, so that in the process of splicing the bottom plate 11, the panel 12 and the side plate 13 to form the box 10, the bottom plate 11, the panel 12 and the side plate 13 are easy to move relatively, and the difficulty of splicing is increased.

Therefore, the panel 12, the side plate 13 and the bottom plate 11 can be welded after the panel 12, the side plate 13 and the bottom plate 11 are assembled to form the box body on the premise that a positioning tool is not needed, so that the problem of troublesome assembly caused by the use of the positioning tool is reduced, and the assembly efficiency is improved.

The inner surface of the side plate body 131 means a surface of the side plate body 131 facing the hollow portion. The side plate grooves 1311 on the inner surface of the side plate body 131 may extend to opposite end surfaces of the side plate body 131 in the extending direction of the side plate 13, or the side plate grooves 1311 on the inner surface of the side plate body 131 may be provided at both ends of the side plate body 131 in the extending direction of the side plate body 131.

The panel body 121 extends in the width direction Y of the chassis 11, and the panel outer flange 122 is provided protruding from both end surfaces of the panel body 121 in the extending direction of the panel body 121.

Taking two panels 12 as a first panel 12a and a second panel 12b, two side panels 13 as a first side panel 13a and a second side panel 13b, and a side panel groove 1311 on an inner surface of the side panel body 131 extending along an extending direction of the side panel 13 as an example, the fitting of the outer panel flange 122 into the corresponding side panel groove 1311 means: the panel outer protrusions 122 of the first panel 12a and the second panel 12b protruding toward the first side plate 13a are respectively fitted into the side plate grooves 1311 of the first side plate 13a, and the panel outer protrusions 122 of the first panel 12a and the second panel 12b protruding toward the second side plate 13b are respectively fitted into the side plate grooves 1311 of the second side plate 13 b.

Not only is the convenience of assembling the panel 12 and the side plate 13 improved, but also the aesthetic property of the box body 10 is improved.

Further, in one or more embodiments of the present application, the side plate 13 includes a side plate inner protrusion 132, and the side plate inner protrusion 132 is disposed on an inner surface of the side plate main body 131; the panel 12 includes an inner panel protrusion 123, the inner panel protrusion 123 is disposed on the inner surface of the panel body 121, and the inner panel protrusion 123 and the inner panel protrusion 132 are connected in a concave-convex fit manner.

Taking the two panels 12 as the first panel 12a and the second panel 12b, and the two side panels 13 as the first side panel 13a and the second side panel 13b, respectively, the panel inner convex portion 123 in the first panel 12a is connected to the side panel inner convex portion 132 of the first side panel 13a and the side panel inner convex portion 132 of the second side panel 13b in a concave-convex fit manner, and the panel inner convex portion 123 in the second panel 12b is connected to the side panel inner convex portion 132 of the first side panel 13a and the side panel inner convex portion 132 of the second side panel 13b in a concave-convex fit manner.

In such a design, the panel inner protrusions 123 may enhance the mechanical strength of the panel 12, and the side panel inner protrusions 132 may enhance the mechanical strength of the side panel 13. Therefore, when the panel inner protrusions 123 and the side plate inner protrusions 132 are connected in a concave-convex fit manner, the connection reliability of the panel 12 and the side plate 13 is improved, and the mechanical strength of the panel 12 and the side plate 13 is enhanced, so that the service life of the box 10 is longer.
