[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2 As shown, the base of the power distribution cabinet has four frame plates 1 and four groups of right-angle connection components. The four frame plates 1 are distributed in a rectangular shape, and the four groups of right-angle connection components are distributed at the connection positions of the frame plates 1;

[0022] like Figure 3 , Figure 4 , Figure 5As shown, the right-angle connection component comprises a top corner pad 2 and a pressing plate 3. The top corner pad 2 is in the shape of a cube. A top corner of the top surface of the top corner pad 2 is integrally fixed with a cube-shaped protrusion 21. Both ends of the frame plate 1 have protruding overlap portions 11. The planes of two adjacent overlap portions 11 are pressed on the surface of the top corner pad 2, and the top planes of the overlap portions 11 touch the side surfaces of the protrusion 21, so that the overlap portions 11 and the protrusion 21 form a flat surface. The pressing plate 3 is located directly above the top corner pad 2. The pressing plate 3 fits the flat surface formed by the overlap portions 11 and the protrusion 21, and the top surface of the pressing plate 3 is flush with the top surface of the frame plate 1. Positioning holes 22 are provided in alignment with the surfaces of the overlap portions 11 and the top corner pad 2. Two positioning columns 31 are symmetrically fixed on the bottom surface of the pressing plate 3. The positioning columns 31 are vertically inserted into the positioning holes 22. A threaded hole is provided on the surface of the protrusion 21, and the surface of the pressing plate 3 has a through hole for the threaded hole.

[0023] When the base is built, the plane of the overlapping portion 11 is pressed against the surface of the top corner pad 2, and the plane of the end of the overlapping portion 11 is in contact with the raised portion 21, so that the four frame plates 1 are accurately distributed in a rectangular shape, and the pressure plate 3 is pressed against the flat surface formed by the overlapping portion 11 and the raised portion 21. The positioning column 31 is vertically inserted into the positioning hole 22 to lock the four frame plates 1 in the plane direction. At this time, the distribution cabinet can be pressed against the surface of the base, and screws are inserted from the inside of the distribution cabinet. The screws pass through the through holes on the surface of the pressure plate 3 and are threadedly connected with the threaded holes on the surface of the raised portion 21. The distribution cabinet and the pressure plate 3, the top corner pad 2, and the frame plate 1 are synchronously fixed and locked to complete the construction and use of the base.

[0024] like Figure 5 As shown, the two overlapping parts 11 pressed on the surface of the same top corner pad 2 are distributed at right angles, and the bottom surface of the pressure plate 3 has a right-angle block 32, which is adapted to be inserted in the right-angle gap between the two overlapping parts 11 to improve the accuracy of the docking position of the frame plate 1.

[0025] like Figure 1 , Figure 2 As shown, a wiring rack 4 is connected between two aligned racks 1 by screws, and a wiring opening 41 for the aligned wiring rack 4 is provided on the surface of the rack 1. The bottom line is conducted along the wiring rack 4 through the wiring opening 41, which is convenient for combing the line.

[0026] One or more of the racks 1 is provided with heat dissipation openings 5 ​​on its surface to improve the heat dissipation efficiency of the power distribution cabinet.

[0027] The inner side of the frame plate 1 is equidistantly fixed with force blocks 6 to increase the anti-deformation strength of the frame plate 1 so that the base can stably support the power distribution cabinet.
