[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution: an insulator that can be easily replaced, including an insulator skirt 1, a steel cap 2 installed at the upper end of the insulator skirt 1, and a steel foot 3 connected to the lower part of the insulator skirt 1; a baffle 10 is installed above the steel cap 2, a limit ring 8 is provided inside the steel cap 2, a positioning seat 9 is connected to the inner wall of the limit ring 8, a spring 4 is connected to the side of the positioning seat 9, an upper positioning rod 5 is connected to the end of the spring 4, and a lower positioning rod 6 is connected to the lower end of the upper positioning rod 5;

[0027] Furthermore, the upper positioning rod 5 has an "L" shaped structure. The upper positioning rod 5 slides through the side wall of the positioning seat 9. The upper positioning rod 5 forms an elastic structure with the positioning seat 9 through the spring 4, which can flexibly adjust the position of the upper positioning rod 5. The insulator skirt 1 is fixed by the engagement of the upper positioning rod 5 with the through hole 13.

[0028] Furthermore, the lower positioning rod 6 has a side "U" shaped structure. The lower positioning rod 6 and the positioning hole 7 engage with each other, allowing the lower positioning rod 6 to move synchronously with the upper positioning rod 5. The engagement of the lower positioning rod 6 and the positioning hole 7 strengthens the fixation of the insulator skirt 1.

[0029] Furthermore, the positioning seat 9 forms a rotating structure with the steel cap 2 through the limiting ring 8. There is a gap between the outer wall of the positioning seat 9 and the inner wall of the baffle 10, which allows the angle of the positioning seat 9 to be flexibly adjusted, so that the relative position between the opening end of the positioning seat 9 and the baffle 10 can be flexibly adjusted, making it convenient to disassemble and assemble the insulator.

[0030] Furthermore, the baffle 10 is symmetrically arranged about the transverse center line of the steel cap 2. The baffle 10 has an "L" shaped structure, which can prevent the baffle 10 from blocking the upper positioning rod 5 and the lower positioning rod 6 when the positioning seat 9 rotates.

[0031] A positioning hole 7 is provided on the side wall of the steel cap 2; a through hole 13 is provided at the lower end of the steel foot 3; a bracket 11 is installed on the edge of the insulator skirt 1, and a reinforcing rod 12 is installed on the side of the bracket 11.

[0032] Furthermore, the upper end of the reinforcing rod 12 has a "C" shaped structure, and two adjacent reinforcing rods 12 are fixed together by bolts, using the reinforcing rods 12 to reinforce and support the assembly of the insulator;

[0033] Specifically, when using this easily replaceable insulator, the upper positioning rod 5 can be pulled away from the positioning seat 9. The upper positioning rod 5 stretches and stores the spring 4. At the same time, the upper positioning rod 5 controls the lower positioning rod 6 installed at the lower end to move away from the steel cap 2. The upper positioning rod 5 moves out of the through hole 13 opened in the steel foot 3, and the lower positioning rod 6 moves out of the positioning hole 7 opened in the steel cap 2. Thus, the fixation of the steel foot 3 and the positioning seat 9 can be released. Then, the positioning seat 9 can be controlled to rotate. The positioning seat 9 rotates stably on the steel cap 2 through the limiting ring 8 until the opening position of the positioning seat 9 is misaligned with the position of the baffle 10. Then, the limiting position of the positioning seat 9 on the steel foot 3 can be released, and the insulator skirt 1 can be driven to move out from the side, making it easy to disassemble and replace the insulator.

[0034] The steel foot 3 of the insulator skirt 1 moves into the opening end of the positioning seat 9, and then the positioning seat 9 can be controlled to rotate in the opposite direction until the opening end of the positioning seat 9 coincides with the position of the baffle 10. Due to the elastic force of the spring 4, the upper positioning rod 5 and the lower positioning rod 6 can be controlled to reset and move. The upper positioning rod 5 passes through the positioning seat 9 and is inserted into the through hole 13, while the lower positioning rod 6 is inserted into the positioning hole 7, which can double lock the steel cap 2 and the steel foot 3, assemble the insulator skirt 1, and reinforce its connection end. At the same time, when assembling the insulator skirt 1, the lower end of the reinforcing rod 12 engages with the upper end of the adjacent reinforcing rod 12 and is fixed with bolts, thereby using the reinforcing rod 12 to further reinforce the assembly end of the insulator skirt 1 and improve its wind resistance. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
