Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

An embodiment of the combined control cabinet is shown in fig. 1, fig. 2, fig. 3, and fig. 5, and includes an upper control cabinet 1 and a lower control cabinet 2 which are stacked, the upper control cabinet and the lower control cabinet respectively include a top plate, a bottom plate, a face plate, a back plate, and two side plates, a limit backup plate 27 extending out of the top plate is disposed on the top of the back plate 24 of the lower control cabinet, and an avoidance sinking platform 17 is disposed on the bottom of the back plate 14 of the upper control cabinet. One side of a limiting backup plate 27 of the lower control cabinet is abutted against the avoidance sinking platform 17, and the other side of the limiting backup plate is flush with the back plate 14 of the upper control cabinet.

The general control cabinet comprises a shell and electronic devices in the shell, the improvement of the embodiment focuses on the structure of the shell, and the internal circuit of the control cabinet has various combinations according to different application occasions, so that the control cabinet can be understood as the prior art and is not the focus of the improvement of the embodiment.

The avoidance sinking platform 17 is a panel parallel to the back plate 14 of the upper control cabinet, and the distance between the panel and the panel 13 of the upper control cabinet is smaller than the distance between the back plate 14 of the upper control cabinet and the panel 13 of the upper control cabinet, that is, the avoidance sinking platform 17 sinks relative to the back plate 14 of the upper control cabinet. The avoidance sinking platform 17 can be a single plate connected with the back plate 14 of the upper control cabinet through welding or conventional fasteners; or may be integrally formed with the back plate 14 of the upper control cabinet, for example, by sheet metal machining.

In both the upper control cabinet 1 and the lower control cabinet 2, one panel sinks towards the rear side and an operation gap 3 is formed at the joint part of the two panels, the bottom of the upper control cabinet and the top of the lower control cabinet are respectively provided with an operation opening for detaching the respective panel, and each operation opening is respectively communicated with the operation gap, as shown in fig. 7, at the front side view angle of the combined control cabinet, each operation opening is at least partially shielded by the panel of the control cabinet.

After the control cabinet is produced, the upper control cabinet 1 and the lower control cabinet 2 are separated into two control cabinets as shown in fig. 1, and the separated control cabinets have relatively small sizes, have low requirements on a press machine and are convenient to transport and store. As the complexity of the control system increases, multiple control cabinets are sometimes required to work in concert. The problem of messy wiring can be brought by randomly placing the control cabinet on the site, and the cleanness and tidiness of a control room are influenced.

The upper control cabinet 1 and the lower control cabinet 2 of this embodiment are superposed up and down, and when stacked, the avoiding sinking platform 17 is abutted against the limit backup plate 27 of the lower control cabinet, so that the alignment is convenient.
