Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically to glass insulators that are easy to install and disassemble. Background Technology

[0002] Insulators are critical components in power systems, used to support conductors and provide electrical insulation. Traditional insulators include porcelain insulators, glass insulators, and composite insulators, which play a vital role in high-voltage transmission lines. Insulators are generally bolted to crossarms and secured by tightening bolts at the bottom. However, bolts are prone to loosening due to rust, resulting in poor insulator stability and inconvenience for maintenance and disassembly. Therefore, this application is submitted. Utility Model Content

[0003] This application proposes an easily installable and disassembled glass insulator to solve the technical problems of existing insulators, which are generally installed on crossarms with bolts and fixed by tightening bolts at the bottom of the insulator. However, this often results in loosening due to bolt rusting, leading to poor insulator stability and inconvenience during maintenance and disassembly. The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0004] An easily installable and disassembled glass insulator includes an insulator body, a connecting post, a threaded protrusion, a base, a limiting ring, a threaded groove, a fixing mechanism, and a limiting mechanism. The connecting post is located at the bottom of the insulator body, and the threaded protrusion is located on the surface of the connecting post. The base is secured to a crossarm. The limiting rings are respectively located on the upper and lower sides of the base. The threaded groove is formed inside the upper and lower limiting rings. The connecting post passes through the upper and lower limiting rings. The threaded protrusion on the connecting post mates with the threaded groove inside the limiting ring. The fixing mechanism is located between the base and the crossarm. The limiting mechanism is located on the top of the upper limiting ring and mates with the connecting post.

[0005] Furthermore, the limiting mechanism includes a fixed base, a torsion spring, and a limiting block. The fixed base is disposed on the upper limiting ring, the limiting block is rotatably disposed on the fixed base, and the torsion spring is disposed between the limiting block and the fixed base.

[0006] Furthermore, the fixing mechanism includes bolts disposed between the base and the crossbeam.

[0007] Furthermore, the height of the limiting ring is 3-5cm.

[0008] Furthermore, the connecting post is cylindrical.

[0009] Furthermore, a reinforcing rib is provided between the limiting ring and the base.

[0010] Compared with the prior art, the beneficial effects of this utility model include: by setting threaded protrusions on the surface of the connecting column and setting threaded grooves on the inner wall of the limiting ring, when installing the insulator body, it is only necessary to tighten the connecting column into the limiting ring to achieve installation. Then, the axial movement of the connecting column and the insulator body is restricted by the limiting block and the torsion spring, which makes it convenient to install and disassemble the insulator body.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] Please see the appendix Figure 1-5 An easy-to-install and disassemble glass insulator includes an insulator body 1, a connecting post 2, a threaded protrusion 3, a base 4, a limiting ring 5, a threaded groove 6, a fixing mechanism, and a limiting mechanism. The connecting post 2 is located at the bottom of the insulator body 1, the threaded protrusion 3 is located on the surface of the connecting post 2, the base 4 is secured to the crossarm, the limiting rings 5 ​​are respectively located on the upper and lower sides of the base 4, the threaded groove 6 is opened inside the upper and lower limiting rings 5, the connecting post 2 passes through the upper and lower limiting rings 5, the threaded protrusion 3 on the connecting post 2 cooperates with the threaded groove 6 inside the limiting ring 5, the fixing mechanism is located between the base 4 and the crossarm, the limiting mechanism is located on the top of the upper limiting ring 5, the limiting mechanism cooperates with the connecting post 2, and the connecting post 2 is cylindrical.

[0021] Using the above technical solution, the insulator body 1 is the main part of the insulator, made of glass material, used to support the conductor and provide electrical isolation. The connecting post 2 is located at the bottom of the insulator body 1 and is used to connect the insulator body 1 to the base 4. The threaded protrusion 3 is located on the surface of the connecting post 2 and cooperates with the threaded groove 6 inside the limiting ring 5 to fix the connecting post 2 and the limiting ring 5. The base 4 is used to lock onto the crossarm, which is a component on the power pole tower used to support the insulator. The limiting rings 5 ​​are respectively located on the upper and lower sides of the base 4 to restrict the movement of the connecting post 2 and ensure the stable connection between the insulator body 1 and the base 4. The threaded groove 6 is opened inside the upper and lower limiting rings 5 ​​and cooperates with the threaded protrusion 3 on the connecting post 2 to achieve fixation. The fixing mechanism is located between the base 4 and the crossarm to fix the base 4 and ensure the stability of the overall structure of the insulator. The limiting mechanism is located on the top of the upper limiting ring 5 and cooperates with the connecting post 2 to further restrict the movement of the connecting post 2 and prevent the connecting post 2 from detaching from the limiting ring 5 due to external force.

[0022] In some embodiments, the limiting mechanism includes a fixed seat 7, a torsion spring 8, and a limiting block 9. The fixed seat 7 is disposed on the upper limiting ring 5, the limiting block 9 is rotatably disposed on the fixed seat 7, and the torsion spring 8 is disposed between the limiting block 9 and the fixed seat 7.

[0023] Using the above technical solution, the fixed seat 7 is set on the upper limiting ring 5 to provide a fixed support point for the limiting block 9. The torsion spring 8 is set between the limiting block 9 and the fixed seat 7 to provide elastic force, so that the limiting block 9 can rotate within a certain range while maintaining the limiting effect on the connecting column 2. The limiting block 9 is rotatably set on the fixed seat 7 and cooperates with the connecting column 2. Through the action of the torsion spring 8, the axial movement of the connecting column 2 is restricted, ensuring that the connecting column 2 will not be dislodged from the limiting ring 5 due to external force.

[0024] Specifically, the height of the limiting ring 5 is 3-5cm to ensure that the limiting ring 5 can effectively restrict the movement of the connecting column 2. At the same time, considering the convenience of installation and disassembly, the height selection needs to balance stability and ease of operation.

[0025] In some embodiments, the fixing mechanism includes bolts 10, which are disposed between the base 4 and the crossarm. The base 4 is firmly fixed to the crossarm by the tightening action of the bolts 10, ensuring the stability and safety of the overall structure of the insulator.

[0026] In some embodiments, a reinforcing rib is provided between the limiting ring 5 and the base 4 to enhance the strength and rigidity of the overall structure, improve the insulator's ability to withstand external forces, and ensure stability even in harsh environments.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
