For this reason, we propose a fixed box structure for indoor power distribution to solve the above problems. Utility Model Content

[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 3 Shown.

[0019] As for the overall structure, the fixed box structure used for indoor power distribution includes: an inner lining frame 1, which is spliced ​​by multiple C-shaped steels 2 corresponding to the edges of the box structure, and the C-shaped steel 2 includes vertical steels 3, horizontal steels 4 and external steels 5. The horizontal steels 4 and external steels 5 are used to relatively connect the ends of the vertical steels 3, and reinforcing steels 6 are also fixedly connected between the middle sections of adjacent vertical steels 3. The bottom of the external steel 5 is welded with an exposed and grooved upward middle steel 7, and a receiving bottom plate 8 is welded and fixed between the middle steels 7 located at the bottom of the inner lining frame 1. The receiving bottom plate 8 is spaced apart from the horizontal steels 4. The inner lining frame 1 is also fixedly welded with a flat partition 9 on the upper half of the vertical steel 3, and a cable hole 10 is opened on the partition 9. The inner lining frame 1 is also screwed with an outer sealing plate 11 on each side corresponding to its box structure.

[0020] From the above records, it can be known that the distribution box in the present application is an integral base frame formed by an inner lining frame 1 composed of C-shaped steel 2, that is, four vertical steels 3 stand on the ground, and then two horizontal steels 4 and external steels 5 are connected to the ends of the vertical steels 3 to form the entire frame of the box structure. At the same time, the middle section of the vertical steel 3 is connected with reinforcing steel 6 to enhance the local rigidity, so that the overall structure is more stable and is conducive to later positioning and installation. At the same time, for the design of the instrument layer, the present application separately designs the partition steel and partition 9 used in the instrument layer. The specific structure is as follows:

[0021] A first partition steel 12 with a relative notch facing inward is fixed by screws at one end of the partition 9, and a second partition steel 13 is also provided below the other end of the vertical steel 3 corresponding to the partition 9. Both ends of the first partition steel 12 and both ends of the second partition steel 13 are welded to the vertical steel 3. One end of the partition 9 is flush with the inner surface of the second partition steel 13, and the other end is spaced apart from the other second partition steel 13. An instrument box sealing plate 14 is also fixed between the second partition steel 13 provided on the partition 9 and the corresponding external steel 5 located at the top of the vertical steel 3. One end of the instrument box sealing plate 14 is fixed with screws flush with the external steel 5, and the other end is bent and fixed with screws inside the second partition steel 13. Furthermore, a wire hole is provided at the bend of the instrument box.

[0022] Through the design of the first partition steel 12 and the second partition steel 13, the instrument layer in the present application, i.e., the partition plate 9 connected to the vertical steel 3, is placed hollow and has no contact with the reinforcing steel 6 on the vertical steel 3. The separately welded partition steel provides sufficient support for the instrument layer, and holes are opened on the partition plate 9 for wiring. In the later process of electrical components being brought into the site, the installation is more stable.

[0023] Similarly, further speaking, the receiving bottom plate 8 is surrounded by surrounding steel 16, and a bottom plate 17 is laid inside the surrounding steel 16. The bottom plate 17 is embedded in the receiving bottom plate 8 and its height does not exceed the surrounding steel 16. A grid-type vent 18 is also provided at the bottom of the outer sealing plate 11 located on the same surface as the instrument box sealing plate 14. The surrounding steel 16 ensures the flatness of the bottom surface in the later stage, and the vent 18 is convenient for the heat dissipation of the entire box.

[0024] 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.
