[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] According to one embodiment of the present invention, Figure 1-Figure 2 Shown.

[0019] For the overall structure, Figure 1 As shown, a pre-installed switch cabinet structure includes: a base frame 1, guide columns 2 positioned at both ends of the base frame 1, a lifting member 3 slidably connected to the guide column 2, a positioning plate 4 and a positioning member 5, the lifting member 3 is used to drive the positioning plate 4 to slide with the axial servo of the guide column 2, the positioning member 5 includes two groups and is symmetrically fixed at both ends of the positioning plate 4, it includes a rotating motor 51, a support seat 52, a rotating shaft 53 and a positioning rod 54, the rotating motor 51 is fixedly connected to the positioning plate 4 through the support seat 52, the two ends of the rotating shaft 53 are respectively rotatably connected to a turntable fixed to the positioning plate 4 by screws, and a rotating block 55 is coaxially fixed on the middle shaft section of the rotating shaft 53, the rotating block 55 is exposed on the turntable and is fixed to the top of the positioning rod 54 with bolts at the exposed end, and the bottom of the positioning rod 54 is used to correspond to the reserved hole 6 of the external switch cabinet.

[0020] like Figure 2 As shown, in this embodiment, the lifting member 3 includes a lifting motor 31, a lifting platform 32 and a slider 33. The slider 33 includes two sliders 33 that are symmetrically slidably connected to each guide column 2. The two ends of the back of the positioning plate 4 are bolted to the sliders 33. The lifting platform 32 is correspondingly fixed to the top of the guide column 2. The tops of the two guide columns 2 pass through the lifting platform 32 and are bolted to the flange 34. The lifting motor 31 is fixed to the center of the lifting platform 32. Its output end passes through the lifting platform 32 and is bolted to the center of the back of the positioning plate 4 through the connecting platform 35. Similarly, the bottom of the guide column 2 is bolted to the base frame 1 through the flange 34. The base frame 1 is also provided with a positioning bolt hole 7 for positioning.

[0021] Through the above-mentioned structural design, during the welding and assembly process of the small switch cabinet, the positioning of the base frame 1 can be first achieved through the positioning bolt hole 7, and then the external control module can synchronously servo-control the lifting member 3 and the positioning member 5, that is, the lifting motor 31 is output first, and through the mutual connection relationship between the connecting table 35, the slide table and the positioning plate 4, the slider 33 can be driven to servo slide in the axial direction of the guide column 2, and the positioning plate 4 rises or falls synchronously. After rising to the specified servo position, the rotating motor 51 starts to work, and its output end drives the rotating shaft 53 to servo rotate between the two turntables through the coupling, and then realizes the rotation of one end of the rotating block 55 in a direction perpendicular to the base frame 1. After rotating to the position of the reserved hole of the external switch box, it corresponds coaxially, and the lifting member 3 is lowered again, so as to achieve the positioning purpose of the positioning rod 54 being embedded in the reserved hole 6 of the external switch cabinet.

[0022] In order to further reduce the positioning range and the servo control process, the present application further fixes limit blocks 8 at both ends of the positioning plate 4 on the outside of the corresponding rotating block 55, and the end of the limit block 8 is fixed with a limit sensor 9 corresponding to the rotating block 55. Through the transmission of the electrical signal of the limit sensor 9, the servo rotation of the positioning rod 54 within the range of 0-90° can be achieved, and the control is simpler and more convenient. In the actual operation process, the positioning rod 54 can also be replaced according to the size of the reserved hole 6 of the different switch cabinets, which has a wider applicability.

[0023] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
