[0021] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1 to Figure 5 A high-strength, low-temperature-resistant porcelain insulator shown in the figure comprises a porcelain part 1, a metal cap 2 is glued to the top of the porcelain part 1 by adhesive, and a docking groove 4 is formed on the metal cap 2. A groove 12 is integrally formed at the bottom of the porcelain part 1, a metal rod 3 is glued to the inside of the groove 12 by adhesive, and a docking ball 5 is integrally formed at the bottom end of the metal rod 3. When two adjacent porcelain insulators are docked, the docking ball 5 on the metal rod 3 of one porcelain insulator is clamped into the docking groove 4 on the metal cap 2 of the other porcelain insulator.

[0023] Considering that the metal rod 3 is easy to slip off the metal cap 2 through the above-mentioned docking method, affecting the stability of the high-voltage line, in order to improve the stability of the docking, a circular groove 6 is formed through the docking ball 5, and circular holes 9 are formed on both sides of the metal cap 2, and the circular holes 9 are connected to the docking groove 4. A bolt 7 is passed through the two circular holes 9, the inner diameter of the circular groove 6 is larger than the outer diameter of the bolt 7, and a nut 8 is threadedly matched at the end of the bolt 7.

[0024] Specifically, when the docking ball 5 is clamped in the docking groove 4, the bolt 7 is passed through the circular hole 9 on one side, the circular groove 6 and the circular hole 9 on the other side in sequence, and then the nut 8 is docked on the end of the bolt 7, so that the docking ball 5 will not slip out of the docking groove 4, thereby improving the stability of the docking of two adjacent porcelain insulators; at the same time, since the inner diameter of the circular groove 6 is larger than the outer diameter of the bolt 7, the metal rod 3 can swing in multiple directions, thereby improving the flexibility of the use of the porcelain insulator.

[0025] In addition, structures such as washers and springs may be provided on the bolt 7 to improve the stability of the fit between the bolt 7 and the nut 8 .

[0026] By providing structures such as the docking ball 5, the circular groove 6 and the bolt 7, the docking ball 5 will not slip out of the docking groove 4, thereby improving the stability of the docking between two adjacent porcelain insulators; at the same time, since the inner diameter of the circular groove 6 is larger than the outer diameter of the bolt 7, the metal rod 3 can swing in multiple directions, thereby improving the flexibility of the use of the porcelain insulator.

[0027] In order to improve the service strength of the porcelain insulator, a reinforcing block 10 is integrally formed on the outer wall of the metal cap 2, and the reinforcing block 10 is attached to the outer wall of the porcelain part 1. A plurality of reinforcing blocks 10 are provided, and the plurality of reinforcing blocks 10 are evenly distributed around the metal cap 2. The reinforcing block 10 can expand the contact area with the porcelain part 1, prevent cracks between the metal cap 2 and the porcelain part 1, and improve the service strength of the porcelain insulator.

[0028] A first inner groove 11 is formed on the inner wall of the metal cap 2. A plurality of first inner grooves 11 are provided to make the inner wall of the metal cap 2 uneven, thereby increasing friction. When the adhesive solidifies, the connection strength between the metal cap 2 and the porcelain component 1 can be improved.

[0029] A second inner groove 13 is provided on the metal rod 3, and the second inner groove 13 is located at one end of the metal rod 3 extending into the groove 12. The second inner groove 13 is arranged in plurality, so that the top end of the metal rod 3 is uneven, increasing friction. When the adhesive solidifies, the connection strength between the metal rod 3 and the porcelain part 1 is improved.

[0030] A protective coating is provided on the outer wall of the porcelain part 1, and the protective coating includes a fluorocarbon coating 14 and a nano-silver coating 15. The fluorocarbon coating 14 is coated on the outer wall of the porcelain part 1, and the nano-silver coating 15 is located outside the fluorocarbon coating 14. The fluorocarbon coating 14 uses a fluororesin coating, which is a coating with fluororesin as the main film-forming substance. Due to the large electronegativity of the introduced fluorine element and the strong carbon-fluorine bond energy, it has the characteristics of weather resistance, heat resistance and low temperature resistance, and has unique non-stickiness and low friction.

[0031] The nano silver coating 15 is a new type of coating with bionic principle and nano modification with a special structure of "lotus leaf self-cleaning effect". The coating uses advanced technology to form a concave-convex morphology similar to lotus leaf on the coating surface during the drying film forming process. The strong surface tension makes it have strong hydrophobic and oil-resistant capabilities. By setting a protective coating on the outer wall of the porcelain part 1, the performance of the porcelain insulator is improved.
