Abstract
Description
Technical Field
[0001] This utility model is an integrally molded insulating support, belonging to the field of insulating supports. Background Technology
[0002] Insulating posts are special insulating components that play a crucial role in overhead transmission lines. In the past, post insulators were primarily used on utility poles. Gradually, they evolved into numerous suspended insulators hanging from one end of high-voltage power line towers. These insulators, typically made of silicone or ceramic, are designed to increase creepage distance and are called insulators. Insulators in overhead transmission lines serve two fundamental functions: supporting the conductors and preventing current from returning to ground. These two functions must be guaranteed. Insulators should not fail due to flashover breakdown caused by changes in environmental and electrical load conditions; otherwise, the insulators will become ineffective, compromising the service life and operational lifespan of the entire line.
[0003] The existing plug-in type insulating support is fixed by plugging it into the support of the overhead line and tightening it with a nut. However, when construction personnel test and locate the cable, the nut is prone to loosening due to the action of the insulating support. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrally molded insulating support to solve the problem that the existing plug-in type insulating support, after being plugged into the support of the overhead line and then tightened with a nut to complete the fixing work, is prone to the problem of the nut loosening due to the action of the insulating support when the construction personnel test and perform cable positioning work.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrally molded insulating support column, the structure of which includes an insulating shell and a cable positioning component connecting base; the cable positioning component is connected to the top of the insulating shell to position the cable; the connecting base is located at the bottom of the insulating shell to provide support and fixation.
[0006] The connecting base includes a base body and a plug rod vertically connected to the center of the bottom surface of the base body. The plug rod includes a rod body, an internal threaded groove at the bottom of the rod body, a telescopic channel located in the interlayer of the rod body, and two deformation grooves located on both sides of the top of the rod body. The opening of the deformation groove is inclined upward, and its bottom extends to form a deformable stabilizing part. The telescopic channel is provided with a transmission component that acts on the stabilizing part to make the stabilizing part deform outward and improve the plug-in firmness.
[0007] Furthermore, in order to perform threaded transmission, the bottom end of the telescopic channel is connected to the internal thread groove. The transmission assembly includes an extension channel horizontally located at the top of the telescopic channel and action blocks slidably located on the left and right sides of the extension channel. The left and right ends of the extension channel are respectively connected to two deformation grooves. The bottom of the opposite end faces of the two action blocks each have an oblique opening. An external thread block is internally threaded to the internal thread groove. The top of the external thread block is provided with an action rod that is movably fitted into the telescopic channel. The top of the action rod has a conical structure that simultaneously tilts the two oblique openings.
[0008] Furthermore, to improve the overall structural robustness, the insulating shell, cable positioning component, and base are integrally molded structures.
[0009] Furthermore, for ease of operation, the bottom surface of the external threaded block is provided with a tool groove.
[0010] Furthermore, to accommodate different tools, the tool groove is one of the following types: straight, cross, or star-shaped.
[0011] Furthermore, in order to act on the stabilizing part and deform it, the two acting blocks extend from the left and right ends of the extension channel respectively and contact the two stabilizing parts respectively.
[0012] Furthermore, in order to provide waterproofing and dustproofing, the outer side of the insulating shell is provided with a number of umbrella-shaped structures from top to bottom, and the interior of the insulating shell is provided with an arc-extinguishing chamber.
[0013] Furthermore, in order to be able to connect with the nut threadedly after being plugged into the support of the overhead line, the outer wall of the pole has an external thread structure.
[0014] The beneficial effects of this utility model are: a double fixing structure is provided on the integrally formed insulating support. The support of the overhead line is initially fixed by the nut, and then the rod with deformable stabilizing part on the insulating support cooperates with the transmission component to internally clamp and fix the support of the overhead line, which improves the firmness of the connection and effectively prevents the nut from loosening when other work is carried out.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a one-piece molded insulating support structure, which includes an insulating shell 1, a cable positioning component 2, and a connecting base 3. The cable positioning component 2 is connected to the top of the insulating shell 1 to position the cable. The connecting base 3 is located at the bottom of the insulating shell 1 to provide support and fixation.
[0023] The insulating shell 1 is made of ceramic material, which has good chemical and thermal stability, strong anti-aging ability, good electrical and mechanical properties, and flexible assembly.
[0024] like Figure 4 As shown, the connecting base 3 includes a base body 31 and a plug rod 32 vertically connected to the center of the bottom surface of the base body 31. The plug rod 32 includes a rod body 321, an internal threaded groove 322 located at the bottom of the rod body 321, a telescopic channel 323 located in the interlayer of the rod body 321, and two deformation grooves 324 located on both sides of the top of the rod body 321. The opening of the deformation groove 324 is inclined upward, and its bottom extends to form a deformable stabilizing part 325. The telescopic channel 323 is provided with a transmission component that acts on the stabilizing part 325 so that the stabilizing part 325 deforms and expands outward to improve the plugging firmness.
[0025] For threaded transmission, the bottom end of the telescopic channel 323 communicates with the internal thread groove 322. The transmission assembly includes an extension channel 326 horizontally located at the top of the telescopic channel 323 and actuating blocks 327 slidably located on the left and right sides of the extension channel 326. The left and right ends of the extension channel 326 communicate with two deformation grooves 324 respectively. The bottom of the opposite end faces of the two actuating blocks 327 each have a bevel 328. An external threaded block 329 is internally threaded to the internal thread groove 322. The top of the external threaded block 329 is provided with an actuating rod 3210 that is movably fitted into the telescopic channel 323. The top of the actuating rod 3210 has a conical structure that simultaneously tilts the two bevels 328.
[0026] To improve the overall structural robustness, the insulating shell 1, cable positioning component 2, and base 31 are integrally molded structures.
[0027] The base 31 has a frustum structure to improve the stability of the support.
[0028] For ease of operation, the bottom surface of the external threaded block 329 is provided with a tool groove.
[0029] The tool's working groove is flat-shaped so that it can be used with a flathead wrench.
[0030] In order to act on the stabilizing part 325 and deform it, two acting blocks 327 extend from the left and right ends of the extending channel 326 respectively and contact the two stabilizing parts 325 respectively.
[0031] To provide waterproofing and dustproofing, the outer side of the insulating shell 1 is provided with several umbrella-shaped structures from top to bottom, and the interior of the insulating shell 1 is provided with an arc-extinguishing chamber.
[0032] In order to be able to be threadedly connected to the nut after being plugged into the support of the overhead line, the outer wall of the rod body 321 has an external thread structure.
[0033] Principle: The insulating support post is placed on the support 4 of the overhead line, such as... Figure 3 As shown, the bracket 4 is pre-set with an insertion hole 41 that fits into the rod 321. After the bottom surface of the base 31 contacts the top surface of the bracket 4, the nut 5 is screwed onto the outer wall of the rod 321 to clamp and fix the bracket 4. At this time, the stabilizing part 325 is located in the insertion hole 41. The operator uses a tool to act on the external thread block 329, causing the thread of the external thread block 329 to move upward, driving the actuating rod 3210 to tilt the two actuating blocks 327 at the same time, so that the actuating blocks 327 act on the two stabilizing parts 325 respectively. The deformation of the stabilizing part 325 clamps and fixes the insertion hole 41 internally, further improving the firmness and effectively preventing the nut 5 from loosening when performing other work.
