Specifically, in order to increase the contact area between the second support part 502 and the power supply device 2, this embodiment sets a support plate 6 between two adjacent second support parts 502. This embodiment takes two support plates 6 arranged opposite to each other on the left and right as an example. After the support plate 6 is installed on the second support part 502, it is suspended in the inner chamber. When installing, the power supply device 2 can be placed on the support plate 6 to prevent it from being separated from the second support part 502; of course, in order to reduce the overall weight of the cabinet 1, the support plate 6 can be hollowed out in multiple places.

[0035] Furthermore, if Figure 4 , Figure 5 As shown, the second support portion 502 is provided with a groove 506, and the support plate 6 is clamped in the groove 506; in this way, the second support portion 502 and the support plate 6 are detachably mounted, and the groove 506 can also limit the support plate 6 from moving in the left and right directions. Preferably, the support plate 6 is provided with a plurality of blocks 7, and the blocks 7 abut against the corresponding second support portion 502; so that the blocks 7 can block the outside of the groove 506 to limit the support plate 6 from moving in the front and back directions. Preferably, the support plate 6 is provided with a plurality of threaded holes 8, so that screws can pass through and then be screwed into the housing of the power supply device 2 to further fix the power supply device 2.

[0036] like Figure 2 As shown, in one embodiment, the mounting column 4 is arranged in the up and down direction, and its upper and lower end surfaces are respectively fixed to the upper and lower inner walls of the inner chamber; so that the mounting column 4 is arranged along the corner of the cabinet 1, the space of the inner chamber is saved, and the structural strength of the cabinet 1 can be improved.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
