In fig. 9, two vertical beams 1 are provided corresponding to the side cabinet plate 9 on the right side in fig. 9, the lateral reinforcement 5 and the vertical reinforcement 6 are provided between the two vertical beams 1. In fig. 9, two vertical beams 1 are provided corresponding to the side cabinet plate 9 on the left side. In some embodiments, if two doors are to be opened (in conjunction with fig. 9, for example, the door 7 and the rear panel 8 can be opened), the transverse reinforcement 5 is disposed between the two vertical beams 2 on the left side of the control cabinet and between the two vertical beams 2 on the right side of the control cabinet.

Therefore, the design of the lateral reinforcement portion and the vertical reinforcement portion does not affect the installation and maintenance of components inside the control cabinet, and those skilled in the art will understand and understand the components and components, and are not described in detail herein.

In some embodiments, the first mounting portion 1011 and/or the second mounting portion 1012 of the cross beam 1 (i.e. the support beam 01) and the vertical beam 2 (i.e. the support beam 01) are provided with hollowed-out holes and mounting holes. The weight is convenient to reduce by arranging the hollowed-out holes, and the connecting and fixing (such as the connecting and fixing with the transverse reinforcing part 5, the vertical reinforcing part 6, the connecting piece 3 and the connecting plate 4 and the mounting and fixing of the internal devices of the control cabinet) are performed by arranging the mounting holes.

With reference to fig. 9, the present utility model further provides a control cabinet, including the frame structure described above.

In a specific real-time process, the left side and the right side of the frame structure are respectively provided with a side cabinet plate 9, the front end of the frame structure is provided with a cabinet door 7, the rear end of the frame structure is provided with a rear cabinet plate 8, and the bottom of the frame structure is sequentially provided with a bottom cover 10, a base 11 and channel steel 12 from top to bottom. The channel steel 12 is designed to be convenient for installing and stabilizing the control cabinet (for example, the channel steel is poured and embedded in concrete, so that the whole control cabinet is stabilized), and meanwhile, the control cabinet is convenient to carry by using a forklift (the fork heads of the forklift are directly inserted into the two channel steel 12, and the fork heads of the forklift are mutually clamped with each other by using the channel steel).

Wherein, frame construction's top has connected gradually top cap 13 and top frame 14 from bottom to top in proper order, in order to be convenient for carry out handling, and top four corners of top frame 14 are provided with lug 15 respectively.
