[0021] Embodiment 1

[0022] As Figures 1 - 3 shown, a control cabinet frame proposed in this embodiment includes a vertical frame and a plug-in 4.

[0023] The vertical frame is a rectangular frame and two groups are arranged side by side front and back. Cross beam b3 is connected between the corresponding four corners of the two groups of vertical frames; the vertical frame includes two vertical beams 1 arranged vertically and horizontally in parallel and two cross beams a2 horizontally distributed and connected between the two ends of the two vertical beams 1. The vertical beams 1, cross beams a2, and cross beam b3 are all closed figures with a twenty-fold cross-sectional contour. The vertical beams 1, cross beams a2, and cross beam b3 all have two perpendicular sides, and both sides have inner grooves, which improves the structural strength and anti-deformation ability. The thicknesses of the vertical beams 1, cross beams a2, and cross beam b3 are all 1.5 mm.

[0024] A total of eight plug-ins 4 are provided, and the plug-ins 4 are connected to the four corners of the vertical frame and connected to the ends of the cross beam b3.

[0025] The vertical beam 1, the cross beam a2 and the cross beam b3 are all made of stainless steel or carbon steel, and the plug-in 4 is made of steel. The plug-in 4 is plugged or welded to the vertical beam 1, the cross beam a2 and the cross beam b3. Among them, the reliability of the welded connection is better.

[0026] The vertical beam 1, the cross beam a2 and the cross beam b3 have the same cross section, and each has an inner side surface 11, an outer side surface 13 and an inner plugging channel 12; the plug-in 4 has three groups of inner connecting platforms 41 adapted to the adjacent vertical beam 1, cross beam a2 and cross beam b3 and abutting against the inner side surface 11, outer connecting platforms 43 abutting against the outer side surface 13 and plugging platforms 42 plugged at the plugging channels 12, so that the vertical beam 1, the cross beam a2 and the cross beam b3 can be respectively plugged on three sides of the plug-in 4.

[0027] The outer ends of the inner connecting platform 41, the outer connecting platform 43 and the plugging platform 42 all have chamfers, and the chamfers play a guiding role to further improve the smoothness when the vertical beam 1, the cross beam a2 and the cross beam b3 are plugged on the plug-in 4.

[0028] In this embodiment, the connection is reliable, the structural strength is high and the seismic resistance is good. The plug-in 4 is plugged on each beam (vertical beam 1, cross beam a2 and cross beam b3) through the inner connecting platform 41, the plugging platform 42 and the outer connecting platform 43. One plug-in 4 can connect three beams. Therefore, using eight plug-ins 4 can assemble each beam into a cuboid structure. The lengths of the vertical beam 1, the cross beam a2 and the cross beam b3 are designed according to the space usage requirements of the control cabinet, cut first and then assembled, with high flexibility.

[0029] Embodiment Two

[0030] As Figure 4 shown, a control cabinet frame proposed in this embodiment. Compared with Embodiment One, in this embodiment, the thicknesses of the vertical beam 1, the cross beam a2 and the cross beam b3 are all 2 mm. The outer peripheral surface contour of the vertical beam 1 in this embodiment is the same as that of the vertical beam 1 in Embodiment One. Similarly, the outer peripheral surface contours of the cross beam a2 and the cross beam b3 are also the same. In this embodiment, the outer side surface of the inner connecting platform 41 of the plug-in 4 is moved inwards, and the plugging platform 42 is reduced to adapt to the clamping and limiting of the vertical beam 1, the cross beam a2 and the cross beam b3 with reduced inner space.

[0031] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to this. Various changes can be made without departing from the gist of the present invention within the knowledge scope of those skilled in the art to which the present invention pertains.
