[0002] Disc suspension insulators refer to suspension insulators composed of disc-shaped insulating parts and connecting hardware. The insulating parts are usually made of electrical ceramics and tempered glass; the hardware is generally composed of steel caps and needle-shaped steel feet. Insulators are widely used in power systems. When installing suspension insulators, the steel feet will penetrate the steel cap and the distribution line installation plate or the fixed conductor installation plate. Then, by penetrating and tightening the steel cap and the steel feet, the insulator can be installed at the application location.

[0003] The current insulator steel foot uses a barb block and an anti-slip structure on the body to increase the installation stability and anti-slip property of the steel foot body on the insulator position.

[0028] Reference Figures 1 to 6 A wear-resistant disc-shaped suspension insulator steel foot comprises a glass member 3, a steel cap 9 arranged at the bottom end of the glass member 3, and a steel foot body 1 penetrating the middle of the glass member 3, a column head 2 and a steel foot column 8 are respectively arranged at both ends of the steel foot body 1, a sealing sleeve 4 is sleeved on the outside of the steel foot body 1, a same clamping member 5 is arranged between the sealing sleeve 4 and the glass member 3 on the outside of the steel foot body 1, a limiting member 6 is arranged between the steel foot body 1 and the steel foot column 8, a same limiting support plate 7 is penetratingly arranged on both sides of the outside of the limiting member 6, a same tightening bolt 10 is arranged between the steel foot column 8 and the steel cap 9, and a screwing block 21 is arranged at one end of the tightening bolt 10 close to the steel foot column 8.

[0031] Through the structural setting of the upper edge of the sealing sleeve 4, when the sealing sleeve 4 and the clamping piece 5 are fitted together, the edge of the sealing sleeve 4 is used to be sleeved on the outside of the clamping piece 5 and fit with the surface of the glass piece 3, thereby increasing the airtightness of the connection between the steel foot body 1 and the glass piece 3.

[0033] By using the transition end 14 , when the steel foot body 1 passes through the glass piece 3 , the transition end 14 of the clamping member 5 can be clamped in the steel foot groove of the glass piece 3 to seal the gap between the steel foot body 1 and the glass piece 3 .

[0034] Reference Figure 4 , a wear-resistant disc-shaped suspension insulator steel foot, further, the limiting member 6 and the glass member 3 penetrate, and the limiting support plate 7 is in contact with the outer surface of the glass member 3.

[0035] When the steel foot and the glass piece 3 are installed through, the limiting piece 6 will pass through the steel foot groove of the glass piece 3 and squeeze the limiting support plate 7. After being squeezed, the limiting support plate 7 shrinks inward and passes through the bottom side of the glass piece 3. By passing the limiting support plate 7 out of the groove, the limiting support plate 7 can be reset from the limiting piece 6 and fit tightly with the outer surface of the glass piece 3, thereby realizing the limiting processing of the steel foot and the glass piece 3.

When the steel foot body 1 and the glass piece 3 are installed, the column head 2 is held, and the steel foot column 8 of the steel foot body 1 is penetrated into the notch of the steel foot in the middle of the glass piece 3. The penetration portion 16 in the limiting support plate 7 is compressed toward the inside of the limiting piece 6 by force, shortening the distance between the two limiting rods 18, and the limiting grooves 17 arranged in an alternating manner limit the inward retraction of the penetration portion 16, thereby increasing the contraction stability of the penetration portion 16. When the penetration portion 16 is completely retracted into the limiting piece 6, the steel foot body 1 can penetrate the glass piece 3, and the steel foot column 8 is arranged at the bottom of the plate of the glass piece 3. The penetration portion 16 passes through the glass piece 3 and is reset from the limiting piece 6. The limiting rod 18 is pressed onto the limiting tube 19, and the penetration portion 16 is closely attached to the outer surface of the glass piece 3. Then, the tightening bolt 10 is used to tighten the tightening bolt 10. The connecting block 21 passes through the first through groove 11 and the steel cap 9, passes through the second through groove 12 and the steel foot column 8 and the tightening groove 13, and then the tightening bolt 10 is rotated 90 degrees, so that the screwing block 21 is screwed into the tightening groove 13 and clamped with the steel foot column 8, so as to realize the mechanical connection between the steel foot column 8 and the steel cap 9; the limiting member 6 is inserted into the glass member 3, and the transition end 14 end of the clamping member 5 is inserted into the steel foot notch on the glass member 3, so that the multiple rubber pads 15 on the clamping member 5 are clamped on the groove wall of the steel foot notch, and the gap between the steel foot body 1 and the glass member 3 is sealed, and the glass member 3 is connected to the steel foot body 1, and then the edge of the sealing sleeve 4 is used to cover the outer surface of the clamping member 5, and fit with the surface of the glass member 3, so as to increase the connection firmness and airtightness between the steel foot and the disc insulator, reduce the use of adhesive, and increase the wear resistance of the steel foot.
