[0028] The utility model provides an anti-pollution type suspension porcelain insulator, such as Figure 1-Figure 3 As shown, the anti-pollution type suspension porcelain insulator comprises a support column 1, a connecting column 2 fixedly sleeved on the supporting column 1, an shed 3 fixedly arranged on the connecting column 2, an anti-pollution structure 4 arranged on the shed 3, and a mounting structure 5 arranged on the shed 3; the mounting structure 5 comprises a mounting block 56 fixedly arranged on a side of the shed 3 away from the connecting column 2, a connecting block 51 fixedly arranged on a side of the mounting block 56 away from the shed 3, a bidirectional threaded rod 52 rotatably mounted inside the connecting block 51, two sliders 53 symmetrically sleeved on the bidirectional threaded rod 52 and capable of approaching or moving away from each other, arcuate rings 54 respectively fixedly arranged on a side of the two sliders 53 away from the connecting block 51 for clamping the electric pole, and a fixing assembly 55 arranged on a side of the arcuate ring 54 away from the connecting block 51;

[0029] When in use, by rotating the bidirectional threaded rod 52 rotatably connected in the connecting block 51, the two sliders 53 symmetrically slidably sleeved on the outside of the bidirectional threaded rod 52 are moved in relative directions, so that the sliders 53 and the arc rings 54 fixedly set on the side of the sliders 53 away from the umbrella skirt 3 are brought closer to each other to clamp the electric pole, and the umbrella skirt 3 fixedly set on the connecting column 2 fixedly sleeved on the supporting column 1 is hung and fixed on the electric pole by the fixing component 55, and the anti-fouling structure 4 is used to keep its surface cleanliness when in use.

[0030] Specifically, a slide groove 511 adapted to the slider 53 is provided on the connecting block 51, and the slider 53 is slidably set in the slide groove 511; when the insulator needs to be suspended and installed, by rotating the bidirectional threaded rod 52 in the connecting block 51, the slider 53 symmetrically slidably sleeved on the outside of the bidirectional threaded rod 52 moves in relative directions along the slide groove 511 adapted to the slider 53 provided on the connecting block 51, so that the slider 53 and the arc ring 54 are close to each other to clamp the electric pole.

[0031] Among them, a plurality of leakage holes 512 connected with the slide groove 511 are opened at the bottom of the connection block 51 for leakage of the connection block 51; when it rains, rainwater leaks out through the leakage holes 512 to prevent excessive accumulation of rainwater, and finally complete the use of the insulator.
