[0028] Embodiment 1:

[0029] The arc surface of the insulator body 1 is provided with a tooth groove 6, and the surface of the insulator body 1 is provided with a first flange 3, which serves as a vertical limit for the insulator body 1. A limit plate 5 is inserted inside the first flange 3, and a guide rod 15 is fixed on the surface of the limit plate 5. The arc surface of the guide rod 15 is sleeved with a spring 14;

[0030] The inner arc surface of the second flange 4 is fixed with teeth 7, and the teeth 7 and the tooth grooves 6 are clamped to prevent the insulator body 1 from rotating on the flange. The outer arc surface of the second flange 4 is provided with a receiving groove 9, and the end of the receiving groove 9 is provided with a notch 10.

[0031] Embodiment 2:

[0032] On the basis of the first embodiment, in order to facilitate the removal of the insulator flange, an annular groove 11 is provided on the surface of the first flange 3, a positioning hole 12 is provided on the outer arc surface of the first flange 3, a positioning rod 13 is fixed on the surface of the limit plate 5, a baffle 16 is fixed on the end of the guide rod 15, and a positioning ring 8 is fixed on the surface of the second flange 4, which plays a positioning role in the connection between the first flange 3 and the second flange 4;

[0033] There are multiple groups of tooth grooves 6, which are circumferentially distributed on the arc surface of the insulator body 1. There are multiple groups of teeth 7, which are circumferentially distributed on the inner arc surface of the second flange 4. The teeth 7 correspond to the tooth grooves 6, and the teeth 7 are clamped in the tooth grooves 6. The teeth 7 and the tooth grooves 6 are clamped together, so that the insulator body 1 cannot rotate on the flange.

[0034] There are multiple groups of annular grooves 11, which are symmetrically distributed on the surface of the first flange 3. There are multiple groups of positioning rings 8, which are symmetrically distributed on the surface of the second flange 4. The positioning rings 8 correspond to the annular grooves 11. The positioning rings 8 are clamped in the annular grooves 11, and the two are movably connected, which plays a positioning role in the connection between the first flange 3 and the second flange 4.

[0035] There are multiple groups of receiving grooves 9, which are circumferentially distributed on the outer arc surface of the second flange 4, and the guide rods 15 correspond to the receiving grooves 9, and the guide rods 15 are clamped in the receiving grooves 9, and the two are movably connected;

[0036] The size of the guide rod 15 is the same as that of the notch 10, the size of the baffle 16 is the same as that of the receiving groove 9, and the size of the baffle 16 is larger than that of the guide rod 15, and the baffle 16 corresponds to the receiving groove 9, and the baffle 16 is stuck in the receiving groove 9, so the baffle 16 will not fall out of the receiving groove 9, and the guide rod 15 will not fall out of the receiving groove 9;

[0037] There are multiple groups of positioning holes 12, which are distributed in a circle on the outer arc surface of the first flange 3. There are multiple groups of positioning rods 13, which are symmetrically distributed on the surface of the limiting plate 5. The positioning rods 13 correspond to the positioning holes 12. The positioning rods 13 are clamped in the positioning holes 12, and the two are movably connected to fix the first flange 3 and the second flange 4.

[0038] In actual use, when the flange needs to be removed, the limit plate 5 is pulled to move. The movement of the limit plate 5 will cause the spring 14 to contract. When the limit rod 13 moves out of the positioning hole 12, stop pulling the limit plate 5, and then rotate the limit plate 5 to rotate it horizontally. At this time, the limit between the first flange 3 and the second flange 4 disappears, and the first flange 3 and the second flange 4 can be easily removed from the surface of the insulator body 1. At the same time, the teeth 7 and the tooth grooves 6 are clamped to prevent the insulator body 1 from rotating on the flange. At the same time, the first flange 3 limits the insulator body 1 vertically, so that the insulator body 1 is fixed in the flange without the need for fixing by bolts. This structure is simple and easy to operate, which realizes the convenient removal of the insulator flange and is conducive to improving its use effect.
