A limiting mechanism 4 is inserted into the limiting hole. The limiting mechanism 4 includes a pin 401, a support spring 402, and a handle 403.

[0027] The upright plate 5 is set at the top and bottom of the first cable box 1. A positioning ring 6 is fixedly connected to one side of the upright plate 5. A clamping mechanism 7 is fixedly connected inside the positioning ring 6. The clamping mechanism 7 includes a buffer spring 701, a left clamping ring 702 and a right clamping ring 703.

[0028] Specifically, the pin 401 is inserted into the inside of the limiting hole, a support spring 402 is sleeved on the surface of the pin 401, and a handle 403 is fixedly connected to one side of the pin 401.

[0029] In this implementation scheme, when in use, since the internal space of gas cabinets of different sizes is different, different sizes of wiring structures need to be set. In order to facilitate the installation by the installers, the wiring structure is assembled in a modular way. The I-shaped block 3 on one side of the second wiring box 8 is inserted into the I-shaped groove on one side of the first wiring box 1. Then, the stretched pin 401 is released. The pin 401 is subjected to the reverse force provided by the support spring 402, and the pin 401 is inserted into the limiting hole opened on the surface of the I-shaped block 3.

[0030] Specifically, the buffer springs 701 are fixedly connected to the inner wall of the positioning ring 6, with a left clamping ring 702 fixedly connected to one side of two buffer springs 701, and a right clamping ring 703 fixedly connected to one side of the other two buffer springs 701.

[0031] In this embodiment, in order to clamp and fix cables of different thicknesses during use, positioning rings 6 are provided at the top and bottom of the first cable box 1 and the second cable box 8. The cable passes through the inside of the positioning ring 6 and is driven by the buffer springs 701 provided on both sides of the inner wall of the positioning ring 6, as well as the left clamping ring 702 and the right clamping ring 703, which tightly clamp the cable passing through the inside.

[0032] Specifically, one side of the support spring 402 is fixedly connected to the surface of the extension block 2, and the other side of the support spring 402 is fixedly connected to the surface of the handle 403.

[0033] In this embodiment, the handle 403 facilitates the movement of the pin 401 by pulling it, and the support spring 402 facilitates the provision of sufficient force to support the movement of the pin 401.

[0034] Specifically, a second cable box 8 is fixedly connected to one side of the I-shaped block 3, and the surface structure of the second cable box 8 is the same as that of the first cable box 1.

[0035] Specifically, the second wiring box 8 has an internal threaded connection to a winding block 9, and the winding block 9 has a through hole inside.

[0036] In this implementation scheme, the I-beam block 3 facilitates connection to the I-beam groove, and the winding block 9 facilitates the bundling of excess cables, avoiding disorderly placement of cables and affecting aesthetics.

[0037] Specifically, each of the four top corners of the winding block 9 is fixedly connected to a winding post 10, and the surface of the winding post 10 is provided with threaded holes.

[0038] Specifically, the upper surface of the winding column 10 is threaded with a positioning bolt 11, and the positioning bolt 11 has an internal thread that matches the threaded hole.

[0039] The working principle and usage process of this utility model are as follows: In order to clamp and fix cables of different thicknesses, positioning rings 6 are set at the top and bottom of the first cable box 1 and the second cable box 8. The cable passes through the inside of the positioning ring 6 and is driven by the buffer springs 701 set on both sides of the inner wall of the positioning ring 6, as well as the left clamping ring 702 and the right clamping ring 703, which tightly clamp the cable passing through the inside.

[0040] When in use, since the internal space of gas cabinets of different sizes is different, different sizes of wiring structures need to be set. In order to facilitate the installation, the wiring structure is assembled in a modular way. The I-shaped block 3 on one side of the second wiring box 8 is inserted into the I-shaped groove on one side of the first wiring box 1. Then, the stretched pin 401 is released. The pin 401 is subjected to the reverse force provided by the support spring 402, and the pin 401 is inserted into the limiting hole opened on the surface of the I-shaped block 3.

[0041] In summary, the internal wiring structure of this gas-insulated cabinet, through the clamping mechanism 7, achieves the effect of clamping and fixing cables of different sizes, improving the flexibility of the device during use. Through the setting of the limiting mechanism 4, the I-beam block 3 and the I-beam groove, multiple wiring boxes can be spliced ​​together. The staff can reasonably select the length of the spliced ​​wiring structure according to the actual situation, so as to meet the installation requirements of gas-insulated cabinets of different sizes.
