Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a glass insulator. Background Technology

[0002] Glass, as a novel insulating material, possesses many outstanding properties. Its manufacturing process is relatively simple and easy to control, ensuring the stability and consistency of product quality. Glass insulators exhibit excellent electrical insulation properties, with relatively stable dielectric constant and loss factor, effectively reducing energy loss and improving power transmission efficiency. Simultaneously, glass insulators possess high mechanical strength, capable of withstanding significant tensile and bending forces, and adapting to complex installation and operating environments.

[0003] Chinese Patent CN221668591U discloses a glass insulator, which includes an insulator body and a pin cap fixedly disposed on the top of the insulator body. The insulator body contains a pin, and the pin cap has an installation groove. This invention slides a fixing block on the pin into the installation groove, and a baffle is provided within the installation groove to prevent the fixing block from falling out, improving the connection effect. Furthermore, no other tools are needed during assembly and disassembly, eliminating concerns about bolts or wrenches falling out and improving safety.

[0004] In practical applications, while existing devices employ liftable baffles to prevent the fixing blocks from detaching from the mounting slots and improve connection effectiveness, they have significant shortcomings. This device relies solely on a single liftable baffle to limit the fixing block's position, resulting in a low tolerance for error. If the baffle malfunctions due to mechanical failure or other unforeseen factors, its limiting function will be greatly diminished, failing to effectively restrain the fixing block. This significantly impacts the installation stability of the glass insulator. Therefore, it is necessary to provide a glass insulator that solves the aforementioned technical problems.

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 1-4 One embodiment provided by this utility model:

[0027] A glass insulator includes: a glass component 1, a steel cap 4 fixedly installed on the top of the glass component 1, a steel foot 2 fixedly installed on the bottom of the glass component 1, a fixing block 3 fixedly installed on the bottom end of the steel foot 2, an installation groove 5 is provided on the steel cap 4, and the installation groove 5 is adapted to the steel foot 2 and the fixing block 3, and symmetrically distributed sliding grooves 6 are provided on the front side of the outer surface of the steel cap 4.

[0028] Slide plates 8 are slidably installed on both slide grooves 6, and the front end of the slide plate 8 extends to the outside of the steel cap 4. Positioning blocks 7 are fixedly installed on the top of both slide plates 8, and the positioning blocks 7 penetrate through the steel cap 4 and extend to the front side inside the mounting groove 5. A first spring 11 is fixedly installed between the slide plate 8 and the bottom of the inner wall of the slide groove 6.

[0029] Fixing holes 16 are provided on both sides of the outer surface of the steel cap 4, and the fixing holes 16 are connected to the interior of the corresponding sliding groove 6. A limiting groove 12 is provided on the top of the inner wall of the fixing hole 16. A positioning post 9 is slidably inserted into the fixing hole 16. A limiting block 14 is fixedly installed on the top of the positioning post 9, and the limiting block 14 is slidably installed on the limiting groove 12. A second spring 15 is fixedly installed inside the limiting groove 12 on one side of the limiting block 14.

[0030] In one embodiment, the opposite ends of the two positioning posts 9 are inclined to facilitate the quick reset of the slide plate 8. Pull rings 10 are fixedly installed on the opposite ends of the two positioning posts 9 to facilitate the movement of the positioning posts 9 and to facilitate the installation and removal of the glass insulator.

[0031] In one preferred embodiment, the surfaces of the steel foot 2, the fixing block 3, and the steel cap 4 are all provided with an anti-corrosion coating, which can effectively prevent the components from being corroded and damaged, and extend their service life.

[0032] In one embodiment, a chamfer 13 is provided on the front side of the bottom of the inner wall of the chute 6 to facilitate the rapid drainage of rainwater, prevent water accumulation from corroding the internal structure, and extend the service life of the device.

[0033] In one preferred embodiment, the top of the inner wall of the slide groove 6 is provided with a sliding hole that matches the positioning block 7, and the positioning block 7 is slidably connected to the sliding hole. The sliding hole is connected to the inside of the mounting groove 5, which facilitates the smooth sliding of the positioning block 7 and its precise entry and exit from the mounting groove 5, ensuring the limiting effect on the fixing block 3 and improving the installation stability of the glass insulator.

[0034] In one embodiment, both the first spring 11 and the second spring 15 are provided with an electroplated layer on their outer walls, which can enhance the corrosion resistance of the springs, extend their service life, ensure their elastic performance is stable, and ensure the long-term reliable operation of the device.

[0035] The working principle of this utility model is as follows: All parts of the device not described herein are the same as or can be implemented using existing technology. During the installation of the glass insulator, the operator first simultaneously presses the two sliding plates 8, causing them to slide downwards within the groove 6, thus compressing the first spring 11. The displacement of the sliding plates 8 moves the positioning block 7, causing it to disengage from the mounting groove 5. At this time, the steel foot 2 and fixing block 3 of the other glass insulator are slid into the groove 5 through its opening, and then the restriction on the two sliding plates 8 is released. Under the elastic force of the first spring 11, the sliding plates 8 drive the positioning block 7 to reset, causing the two positioning blocks 7 to form a blocking structure at the opening of the mounting groove 5, thereby ensuring the stable connection of the fixing block 3 within the mounting groove 5 and preventing it from disengaging. This device uses the two positioning blocks 7 to limit the position of the fixing block 3 within the mounting groove 5, forming a double protection mechanism. Furthermore, the adjustment structures of the two positioning blocks 7 are independent of each other and do not interfere with each other. Even if one of the positioning blocks 7 fails, the other positioning block 7 can still ensure that the fixed block 3 is in a stable position in the mounting groove 5, which significantly improves the installation stability of the glass insulator.

[0036] When positioning the positioning block 7, the operator must first pull the two pull rings 10. The movement of the pull rings 10 causes the positioning post 9 to slide within the fixing hole 16. At the same time, the positioning post 9 drives the limiting block 14 to slide within the limiting groove 12 and compresses the second spring 15. As the positioning post 9 moves, it disengages from the sliding groove 6. At this time, the operator can operate the position of the positioning block 7 through the sliding plate 8. Subsequently, when the sliding plate 8 returns to its original position under the elastic action of the first spring 11, it will contact the inclined end of the positioning post 9, thereby automatically pushing the positioning post 9 to slide into the fixing hole 16 until the sliding plate 8 passes the positioning post 9. At this time, the positioning post 9 is locked at the bottom of the sliding plate 8 under the elastic action of the second spring 15, locking the position of the sliding plate 8 and ensuring the stability of the positioning block 7 in the mounting groove 5, further improving the installation stability of the glass insulator. As a self-mounted locking structure of the steel cap 4, the positioning post 9 has the characteristics of simple structure and convenient operation. The operator does not need to use other cable ties or ribbons for binding and limiting, making it highly practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
