[0027] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0028] Reference Figure 1-4 The utility model embodiment provides a fixing bolt for limiting the installation of an electric power distribution cabinet, which includes: a base plate 1, the base plate 1 is the bottom plate of the electric power distribution cabinet, a column foot assembly 2 is arranged at the bottom of the base plate 1, a fastening ring 3 is arranged on the column foot assembly 2, and a foot sleeve assembly 4 is arranged below the fastening ring 3.

[0029] The column base assembly 2 includes a column 201, a bottom hole 202 and a limiting groove 203. The column 201 is distributed at the four corners of the bottom of the power distribution cabinet and is used to support and limit the power distribution cabinet. The bottom of the column 201 is provided with a bottom hole 202 and a limiting groove 203. There are multiple limiting grooves 203 and they are evenly distributed around the bottom hole 202. The bottom hole 202 is conical, and the limiting groove 203 is located on the inner side of the bottom hole 202. The fastening ring 3 is threadedly connected to the column 201.

[0030] The foot cover assembly 4 includes an outer shell 401, side holes 402, an inner shell 403, a bottom shell 404, a fixing pin 405, a bottom pin 406 and a limit block 407. The circumferential surface of the outer shell 401 is threadedly connected to the fastening ring 3. The circumferential surface of the outer shell 401 is provided with side holes 402. The number of side holes 402 is provided in plurality and is evenly distributed on the outer shell 401. The inner shell 403 is fixedly connected to the inner circumferential surface of the outer shell 401. The inner shell 403 is funnel-shaped to facilitate the insertion of the column 201 into the bottom shell 404. The bottom of the inner shell 403 is fixedly connected to the bottom shell 404. The inner shell 403 and the bottom shell 404 are both made of soft rubber. The column 201 is located inside the bottom shell 404. When the column 201 is inserted into the bottom shell 404, the bottom shell 404 expands and expands the surrounding fixing pins 405 outward, so that the fixing pins 405 are inserted into The bottom shell 404 is fixedly connected to the ground around it, thereby playing a stabilizing role. A fixing pin 405 is fixedly connected to the circumferential surface of the bottom shell 404, and the fixing pin 405 forms an angle of 30 degrees with the vertical line. There are multiple fixing pins 405, which are evenly distributed on the circumferential surface of the bottom shell 404, and the insertion into the ground is smoother. The fixing pin 405 is located inside the side hole 402, and a bottom pin 406 is fixedly connected to the inner bottom surface of the outer shell 401. The bottom pin 406 is conical, and a limiting block 407 is fixedly connected to the conical surface of the bottom pin 406. There are multiple limiting blocks 407, which are evenly distributed on the conical surface of the bottom pin 406. The limiting groove 203 and the limiting block 407 are correspondingly arranged up and down. When the column 201 is inserted into the bottom shell 404, the bottom hole 202 of the column 201 corresponds to the bottom pin 406, and the limiting groove 203 corresponds to the limiting block 407, thereby better limiting the power distribution cabinet.

[0031] Working principle: bury the foot cover assembly 4 under the ground, and the power distribution cabinet rises and falls, so that the column 201 is inserted into the bottom shell 404, and the bottom shell 404 expands, thereby expanding the surrounding fixing pins 405 outward, and then the fixing pins 405 are inserted into the surrounding ground, thereby playing a stabilizing role, and then rotating the fastening ring 3 to make the fastening ring 3 and the outer shell 401 threadedly connected, so as to form a stable limit fixation. When disassembly is required, just loosen the fastening ring 3, lift the power distribution cabinet, and take out the foot cover assembly 4.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
