[0006] In some embodiments, the support frames on both sides are respectively provided with a plurality of first docking holes spaced apart along the vertical direction, and the first docking holes on the support frames on both sides are arranged opposite to each other.

[0007] In some embodiments, the middle portion of the connecting plate is bent at 90°, a second docking hole is provided on one side of the connecting plate, and a third docking hole is provided on the other side, and the second docking hole is screwed to the first docking hole by bolts.

[0008] In some embodiments, fourth docking holes are respectively provided on both sides of the rear sealing plate, and the fourth docking holes are screwed to the third docking holes by bolts.

[0009] In some embodiments, the fourth docking hole is a convex hole structure.

[0010] In some embodiments, the rear side of the cabinet is detachably connected to two rear covering plates in the vertical direction; four connecting plates are detachably connected to the support frames on both sides, and the connecting plates on both sides at the same height are screwed to the same fourth docking hole.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] In this application, after connecting the connecting plate to the supporting frame on the rear side of the cabinet, a convex hole is opened on the rear sealing plate. During installation, the rear sealing plate and the connecting plate are screwed and fixed. The bolts will not protrude outside the cabinet, ensuring the aesthetics. The installation process will not be restricted by the space inside the cabinet, and the installation operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] refer to Figures 1 to 4 The present application provides a low-voltage cabinet rear packaging structure, including: a cabinet body and at least one rear sealing plate 1, two support frames 2 are arranged on both sides of the rear of the cabinet body, and the support frames 2 on both sides are respectively detachably connected with at least one connecting plate 3, and the rear sealing plate 1 is respectively detachably connected to the connecting plates 3 on both sides.

[0019] In some embodiments, the support frames 2 on both sides are respectively provided with a plurality of first docking holes 4 spaced apart in the vertical direction, and the first docking holes 4 on the support frames 2 on both sides are arranged opposite to each other. The connecting plate 3 can be connected to different first docking holes 4 to meet the actual installation requirements of the rear sealing plate 1.

[0020] In some embodiments, the middle portion of the connecting plate 3 is bent at 90°, a second docking hole 5 is provided on one side of the connecting plate 3, and a third docking hole 6 is provided on the other side. The second docking hole 5 is screwed to the first docking hole 4 by bolts.

[0021] In some embodiments, fourth docking holes 7 are respectively provided on both sides of the rear cover plate 1 , and the fourth docking holes 7 are screwed to the third docking holes 6 by bolts.

[0022] In some embodiments, the fourth docking hole 7 is a convex hole structure, and the bolts will not protrude outside the cabinet, ensuring aesthetics.

[0023] In some embodiments, two rear cover plates 1 are detachably connected to the rear side of the cabinet in the vertical direction; four connecting plates 3 are detachably connected to the supporting frames 2 on both sides, and the connecting plates 3 on both sides at the same height are screwed to the same fourth docking holes 7. In this embodiment, two rear cover plates 1 are connected to the rear side of the cabinet.
