[0002] The anti-reverse connection structure of high-voltage insulators is a mechanical locking mechanism designed on the metal fittings of the insulators. Its core function is to prevent the steel feet from being completely pulled out of the iron cap when the insulator is under tension, due to long-term stress or deterioration of the internal cement adhesive. This would lead to the insulator string breaking and line accidents.
[0003] In the prior art, such as Chinese Patent No. CN221079738U, a reverse-blocking connection structure for a high-voltage insulator includes a conduit with a snap-fit hole on its outer wall. A first connecting post is fixedly connected to the bottom wall of the conduit. A first groove is formed inside the first connecting post, and a first spring is disposed inside the first groove. One end of the first spring is fixedly connected to the inside of the first connecting post, and the other end of the first spring is fixedly connected to one side of a second connecting post. A ball bearing is disposed on the other side of the second connecting post. A limit groove is formed inside the first connecting post, and a limit block is fixedly connected to the outer wall of the second connecting post. In this utility model, the cooperation between components such as the conduit, snap-fit hole, and groove achieves the effect of rapid installation of equipment, solving the problem of the overly cumbersome process when installing insulators and improving the work efficiency of workers to a certain extent.
[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: the buckle holes and ball bearings are exposed, making the insulators prone to falling off under external force, reducing the connection effect and posing certain safety hazards. Moreover, using only ball bearings for positioning results in low stability, making the insulators prone to shaking after installation, thereby reducing the service life of the insulators. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the existing technology where the buckle hole and ball bearings are exposed, making the insulator easy to fall off under external force, reducing the connection effect and posing certain safety hazards. Moreover, using only ball bearings for positioning has low stability, making the insulator prone to shaking after installation, thereby reducing the service life of the insulator.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a reverse-blocking connection structure for a high-voltage insulator, comprising: an insulator body, and further comprising: A connecting component is disposed at one end of the insulator body, the connecting component comprising: A connecting cylinder is fixedly disposed at one end of the insulator body. Two connecting blocks are fixedly disposed at the upper end of the outer surface of the connecting cylinder, and grooves are formed on the outer surface of the connecting blocks. A connecting column is movably disposed inside the connecting cylinder; A positioning component is disposed on the outer surface of the connecting cylinder.
[0007] Preferably, the connection component further includes: A first spring is fixedly disposed inside the groove, and a positioning ball is fixedly disposed at the other end of the first spring; A limiting plate is fixedly installed on the top of the connecting column, and two L-shaped plates are fixedly installed on the outer surface of the limiting plate; Among them, the two L-shaped plates are symmetrical; A limiting hole is formed at the center of the inner surface of the L-shaped plate.
[0008] The technical effect of adopting the above-mentioned further solution is as follows: after the connecting column is embedded inside the connecting cylinder, the connecting column is rotated to drive the two L-shaped plates to rotate 90 degrees, the L-shaped plates coincide with the connecting block, and the positioning ball is embedded inside the limiting hole under the elastic force of the first spring, so that the L-shaped plate is connected to the connecting block.
[0009] Preferably, the positioning component includes: Both grooves are formed inside the connecting cylinder; An annular groove is formed inside the connecting cylinder near the bottom end of the slide groove; Two positioning blocks are fixedly installed at the lower end of the connecting column, and positioning holes are provided on the outer surface of the positioning blocks; The two positioning blocks are symmetrical.
[0010] The technical effect of adopting the above-mentioned further solution is that the connecting column drives the two positioning blocks to be embedded in the interior of the sliding groove, so that the positioning blocks are embedded in the interior of the annular groove through the sliding groove. While the connecting column drives the L-shaped plate to rotate, the positioning blocks rotate in the interior of the annular groove. When the positioning blocks rotate 90 degrees, the positioning pin is embedded in the interior of the positioning hole under the elastic force of the second spring. The positioning pin positions the positioning block, making it more stably embedded in the interior of the annular groove. The positioning block can improve the stability of the connecting column.
[0011] Preferably, two locating pins are movably disposed at the lower end of the outer surface of the connecting cylinder, and the two locating pins are symmetrical to each other.
[0012] The technical effect of adopting the above-mentioned further solution is that the positioning pin positions the positioning block, making it more stably embedded in the annular groove.
[0013] Preferably, a second spring is fixedly provided on the outer surface of the positioning pin, and the other end of the second spring is connected to the connecting cylinder.
[0014] The technical effect of adopting the above-mentioned further solution is that the positioning pin is embedded inside the positioning hole under the elastic force of the second spring.
[0015] Preferably, the inner surface of the L-shaped plate is provided with a guide groove.
[0016] The technical advantage of adopting the above-mentioned further solution is that the guide groove is located on one side of the limiting hole, which facilitates the guidance of the positioning ball.
[0017] Preferably, an iron cap is fixedly provided on the top of the limiting plate.
[0018] The technical effect of adopting the above-mentioned further solution is that the iron cap can protect the connecting column.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, after the connecting column is embedded inside the connecting cylinder, the connecting column is rotated to drive the two L-shaped plates to rotate 90 degrees. The L-shaped plates coincide with the connecting block, and the positioning ball is embedded inside the limiting hole under the elastic force of the first spring, so that the L-shaped plate is connected to the connecting block. The L-shaped plate is fixedly installed on the outer surface of the limiting plate. Therefore, the connecting column can be positioned by the limiting plate so that it is connected to the connecting cylinder.
[0020] 2. In this utility model, the connecting column drives two positioning blocks to embed into the interior of the sliding groove, so that the positioning blocks are embedded into the interior of the annular groove through the sliding groove. While the connecting column drives the L-shaped plate to rotate, the positioning blocks rotate inside the annular groove. When the positioning blocks rotate 90 degrees, the positioning pin is embedded into the interior of the positioning hole under the elastic force of the second spring. The positioning pin positions the positioning block, making it more stably embedded inside the annular groove. The positioning block can improve the stability of the connecting column, so that it can better drive the iron cap to connect with the insulator body, ensuring that the insulator body will not completely disintegrate.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1, as Figure 1-4 As shown, this utility model provides a reverse-blocking connection structure for a high-voltage insulator, including: an insulator body 1, a connecting component, and a positioning component; The connecting assembly includes: a connecting cylinder 101 is fixedly installed at one end of the insulator body 1, and two connecting blocks 109 are fixedly installed at the upper end of the outer surface of the connecting cylinder 101, with grooves 110 formed on the outer surface of the connecting blocks 109; A first spring 111 is fixedly connected inside the groove 110, and a positioning ball 112 is fixedly installed at the other end of the first spring 111. The positioning ball 112 moves out of the groove 110 under the elastic force of the first spring 111 and then is inserted into the limiting hole 116. A connecting post 104 is movably embedded inside the connecting cylinder 101. A limiting plate 103 is fixedly installed on the top of the connecting post 104. Two L-shaped plates 115 are fixedly installed on the outer surface of the limiting plate 103. A limiting hole 116 is opened at the center of the inner surface of the L-shaped plate 115. Among them, the two L-shaped plates 115 are symmetrical, and the positioning ball 112 can position the connecting column 104 after being embedded in the limiting hole 116; An iron cap 102 is fixedly installed on the top of the limiting plate 103; A guide groove 117 is provided on the inner surface of the L-shaped plate 115.
[0026] In this embodiment, the guide groove 117 is located on one side of the limiting hole 116, which facilitates the guidance of the positioning ball 112, making it easier for the positioning ball 112 to be embedded into the interior of the limiting hole 116.
[0027] Example 2, as Figure 1-4 As shown, the positioning component includes: two sliding grooves 107 are opened inside the connecting cylinder 101, and an annular groove 108 is opened at the bottom end of the sliding groove 107; Two positioning blocks 105 are fixedly installed at the lower end of the connecting column 104, and positioning holes 106 are provided on the outer surface of the positioning blocks 105. The positioning block 105 is movably embedded in the annular groove 108 and the sliding groove 107. It is embedded in the annular groove 108 through the sliding groove 107, and then rotates inside the annular groove 108 with the connecting column 104. Two positioning pins 113 are movably embedded at the lower end of the outer surface of the connecting cylinder 101, and the two positioning pins 113 are symmetrical to each other; A second spring 114 is fixedly connected to the outer surface of the positioning pin 113, and the other end of the second spring 114 is connected to the connecting cylinder 101.
[0028] In this embodiment, the positioning pin 113 is embedded in the positioning hole 106 under the elastic force of the second spring 114, which can position the positioning block 105 and connect it to the connecting cylinder 101.
[0029] Working principle: After the connecting post 104 is embedded inside the connecting cylinder 101, the connecting post 104 is rotated to drive the two L-shaped plates 115 to rotate 90 degrees. The L-shaped plates 115 coincide with the connecting block 109. The positioning ball 112 is embedded inside the limiting hole 116 under the elastic force of the first spring 111, so that the L-shaped plate 115 is connected to the connecting block 109. The L-shaped plate 115 is fixedly installed on the outer surface of the limiting plate 103. Therefore, the connecting post 104 can be positioned by the limiting plate 103 so that it is connected to the connecting cylinder 101. The connecting post 104 drives two positioning blocks 105 to embed into the interior of the sliding groove 107, so that the positioning blocks 105 are embedded into the interior of the annular groove 108 through the sliding groove 107. While the connecting post 104 drives the L-shaped plate 115 to rotate, the positioning blocks 105 rotate accordingly inside the annular groove 108. When the positioning blocks 105 rotate 90 degrees, the positioning pin 113 is embedded into the interior of the positioning hole 106 under the elastic force of the second spring 114. The positioning pin 113 positions the positioning block 105, making it more stably embedded inside the annular groove 108. The positioning block 105 can improve the stability of the connecting post 104, so that it can better drive the iron cap 102 to connect with the insulator body 1, ensuring that the insulator body 1 will not completely disintegrate.
