The extrusion fixing assembly 3 is vertically connected to the second support frame 7, which plays the role of achieving the shielding purpose faster.

[0044] The technical solution of the utility model can sleeve the shielding aluminum ring 5 on the line inside the wire rack and enhance the structural strength by arranging the connecting rod 1, the first support frame 6 and the second support frame 7. By vertically arranging the extrusion fixing component 3 on the second support frame 7, the transmission line shielding ring can be fixed to the line inside the wire rack.

[0045] In an optional embodiment of the present invention, the first support frame 6 is vertically connected to two adjacent connecting rods 1; and the second support frames 7 are cross-connected to each other.

[0046] like Figure 1 As shown, in the above embodiment, the first support frame 6 encloses a closed area between the multiple connecting rods 1, and the second support frame 7 is arranged in the closed area. Both ends of the second support frame 7 are fixedly connected to the position where the first support frame 6 is connected to the connecting rod 1, and can fix the extrusion fixing assembly 3. Preferably, when four connecting rods 1 are provided in the power transmission line shielding ring of the present application, the number of the first support frames 6 is four and encloses a rectangular area, the number of the second support frames 7 is two and cross-connected in the rectangular area, and both ends of the second support frame 7 are connected to the corners of the rectangular area.

[0047] In an optional embodiment of the utility model, the first support frame 6, the second support frame 7 and the shielding aluminum ring 5 are all located in the same plane; the first support frame 6, the second support frame 7, the shielding aluminum ring 5 and the connecting rod 1 are fixedly connected via a connecting seat 4.

[0049] In an optional embodiment of the present invention, the shielding aluminum ring 5 is a hollow ring structure; the shielding aluminum ring 5 is made of aluminum alloy material.

[0050] In the above embodiment, the shielding aluminum ring 5 is a hollow ring structure, which increases the area of ​​the shielding ring and improves the shielding effect.

[0051] The shielding aluminum ring 5 is supported by aluminum alloy material, which has the advantages of high hardness, light weight and better shielding effect.

[0052] In an optional embodiment of the present invention, the extrusion fixing assembly 3 includes a wire tube 8 and fixing rings 11 sleeved at both ends of the wire tube 8 .

Specifically, the diameter of the fixing ring 11 is slightly larger than the outer diameter of the wire tube 8, and a threaded seat 12 for connecting an extrusion bolt 13 is fixedly connected to the outer surface of the fixing ring 11. The threaded seat 12 and the fixing ring 11 are both provided with threaded holes, and the threaded holes on the threaded seat 12 and the fixing ring 11 are all located on the same straight line. The extrusion bolt 13 can squeeze the wire tube 8 through the threaded holes, thereby fixing the line in the wire tube 8.

[0056] Furthermore, a compression gasket 10 is provided at a position on the inner surface of the wire tube 8 corresponding to the threaded hole, and the compression groove 9 is also provided at a position on the inner surface of the wire tube 8 corresponding to the compression gasket 10. When in use, when the compression bolt 13 rotates downward to compress the wire tube 8, the wire tube 8 is deformed, and the cables in the wire tube 8 are squeezed into the compression groove 9 through the compression gasket 10, so that the cables can be in close contact with the wire tube 8, thereby playing a role in fixing the cables to the wire tube 8.

[0057] In an optional embodiment of the present invention, the middle portion of the wire tube 8 is vertically connected to the second support frame 7 .
