[0132] During installation, the partition piece 130 is pre-fixed on the bottom surface of the second box body 120 through the support part 131, then the partition piece 130 is connected with the first box body 110 along with the second box body 120, and the partition piece 130 separates the first box body 110 and the second box body 120, thereby improving the assembly efficiency.

[0133] In the third mode, the box body 100 is further provided with a bending part 160 extending inward, the bending part 160 is parallel to the box cover, a sealing piece 300 is arranged between the box cover 200 and the bending part 160, and the sealing piece 300 is used for sealing the gap between the box body 100 and the box cover 200.

[0134] The bending part 160 and the box cover 200 are in surface contact, which increases the contact area between the box body 100 and the box cover 200, and is beneficial to increase the contact area between the sealing piece 300 and the box body 100, thereby improving the sealing effect.

[0135] As far as possible, various aspects and features described and shown in the specification can be applied independently, and these independent aspects can be taken as the subject of a divisional application.

[0136] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0137] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
