[0026] The following examples further illustrate the content of this application, but should not be construed as limiting this application. Without departing from the spirit and substance of this application, modifications or substitutions made to the methods, steps or conditions of this application are within the scope of this application.

[0027] In some embodiments, Figure 1 and Figure 2 As shown, a conductor anti-drop buckle on an insulator includes:

[0028] The lower clamping part 1 is provided with a first bolt groove 103;

[0029] The upper pressure cover 2 is provided with a second bolt groove 201;

[0030] The first bolt assembly 301 includes a first bolt 3011 and a first nut 3012, one end of the first bolt 3011 is hinged on the lower clamping portion 1 or the upper pressure cover 2, when one end of the first bolt 3011 is hinged on the lower clamping portion 1, the other end of the first bolt 3011 is fixed in the second bolt groove 201 through the first nut 3012, when one end of the first bolt 3011 is hinged on the upper pressure cover 2, the other end of the first bolt 3011 is fixed in the first bolt groove 103 through the first nut 3012, and the first bolt 3011 can be relatively rotated into or out of the first bolt groove 103 and the second bolt groove 201;

[0031] The second bolt assembly 302 connects the upper clamping portion 1 and the upper pressure cover 2;

[0032] The conductor is fastened to the insulator by a space enclosed by the upper gland 2 , the lower clamping portion 1 , the first bolt assembly 301 and the second bolt assembly 302 .

[0033] The insulator includes a plurality of sheds, which surround the periphery of the insulator. Each shed is wide at the bottom and narrow at the top. This design can effectively prevent moisture and dirt from accumulating on the surface of the insulator and maintain its good electrical performance. The lower clamping part is clamped on the insulator column between the top platform of the insulator and the shed, and is fixed on the insulator column by the clamping arm. All parts do not need to be removed during installation and disassembly. The whole structure is integrated with design, without separate scattered parts, which can effectively avoid the risk of parts falling during high-altitude operation, and is suitable for high-altitude operation.

[0034] The upper gland 2 and the lower clamping part 1 are connected as a whole by the first bolt assembly 301 and the second bolt assembly 302, so as to achieve a stable fixation of the conductor on the insulator. During use, the conductor is placed in the groove at the top of the insulator, and then pressure is applied by the upper gland 2 to fix it in the groove. The lower clamping part 1 is fixed on the column of the insulator by the clamping arm, ensuring the stability and reliability of the entire anti-drop buckle.

[0035] The second bolt 3021 passes through the through holes on the lower clamping part 1 and the upper gland 2 and is fixed by a nut. The lower clamping part and the upper gland can rotate with the first bolt as the axis. One end of the second bolt 3021 is hinged to the lower clamping part 1, and the other end is fixed to the upper gland by a nut. This design enhances the integrity of the conductor anti-drop buckle on the insulator, effectively avoids the risk of parts falling during high-altitude operations, and is more convenient to install.

[0036] In some embodiments, Figure 2 As shown, the upper pressure cover 2 is provided with a second bolt groove 201 , and when the upper pressure cover 2 rotates around the first bolt 301 , the second bolt 3021 can be screwed into or out of the second bolt groove 201 .

[0037] The shape and size of the second bolt slot 201 can be customized according to actual needs. For example, when a larger rotation angle is required to adjust the position of the upper gland, the second bolt slot can be designed as a longer arc slot. In this way, during the rotation of the upper gland, the first bolt 3011 can move in a longer range, thereby providing more adjustment space.

[0038] In addition, the bottom of the second bolt groove 201 can be provided with some anti-skid textures or coatings to increase the friction between the first bolt 3011 and the second bolt groove 201, so as to prevent the first bolt 3011 from accidentally slipping out during the adjustment process. In addition, the second bolt groove 201 can also be designed to have a certain inclination angle, so that when the first bolt 3011 is screwed in or out, the height and angle of the upper pressure cover can be adjusted more easily. Such a design can not only improve the convenience of operation. During the installation or disassembly process, there is no need to completely unscrew the nut on the first bolt 3011, but only need to loosen the nut and rotate the upper pressure cover 2 with the second bolt 3021 as the axis, so that the second bolt groove 201 on the upper pressure cover 2 can be smoothly separated and combined with the first bolt 3011. This design makes the installation and disassembly process of the anti-drop buckle more convenient.

[0039] In some embodiments, the lower clamping portion 1 includes a first clamping arm 101 and a second clamping arm 102, one end of the first clamping arm 101 and the second clamping arm 102 are hinged by the second bolt 3021, the other end of the first clamping arm 101 is hinged to the first bolt 3011, and the other end of the second clamping arm 102 is provided with a plurality of first bolt grooves 103 that cooperate with the first bolt 3011.

[0040] The first clamping arm 101 and the second clamping arm 102 are both arc-shaped, and the two clamping arms tightly clamp the insulator column therebetween to provide good support and stability. The number and position of the first bolt slots 103 can be adjusted as needed to meet the needs of insulator columns of different sizes and shapes.

[0041] When in use, first place the insulator between the first clamping arm 101 and the second clamping arm 102, adjust the space between the two clamping arms so that they fit with the insulator column, and then rotate the first bolt 3011 to make it cooperate with the first bolt groove 103 to fix the two clamping arms. This can adapt to insulators of different sizes and stably fix them in the desired position.

[0042] In addition, in order to further improve the stability and reliability of clamping, anti-slip grooves or anti-slip materials such as rubber pads can be provided on the inner sides of the first clamping arm 101 and the second clamping arm 102 to increase the friction between the insulating plate and prevent it from slipping or moving.

[0043] In some embodiments, the first clamping arm 101 and the second bolt 3021 are fixed by a top screw, so that the first clamping arm 101 cannot rotate around the second bolt 3021, and the second clamping arm 102 rotates around the second bolt 3021 to adjust the space between the clamping arms. In this way, the space between the clamping arms can be adjusted by adjusting only the second clamping arm, so as to easily adapt to insulator columns of different sizes. This design also allows the user to optimize the clamping effect and improve work efficiency by adjusting the second clamping arm without changing the position of the first clamping arm. Preferably, a scale line is provided on the second clamping arm 102, and the user can accurately control the size of the space between the clamping arms according to the scale line. This design enables the user to more accurately grasp the clamping force and avoid clamping too tight or too loose.

[0044] In some embodiments, the upper pressure cover 2 is a diamond-shaped frame, a through hole is opened on the first vertex of the diamond-shaped frame, the first bolt passes through the through hole and is fixed by a nut, and the second bolt groove is fixedly connected to the second vertex opposite to the first vertex.

[0045] The line connecting the third vertex 203 and the fourth vertex 204 of the diamond frame is parallel to the wire, and the third vertex 203 and the fourth vertex 204 are provided with rubber coating, and the contact surface between the rubber coating and the wire is provided with a groove matching the wire.

[0046] The diamond-shaped frame design of the upper pressure cover not only provides a stable structure, saves materials, reduces weight, but also optimizes its interaction with the wires. The diamond design enables the upper pressure cover to evenly distribute force when under pressure, effectively preventing wire damage caused by excessive stress at a single point. At the same time, the design of the diamond frame also provides sufficient operating space, allowing staff to easily operate when installing, maintaining or adjusting the wires. The through hole design on the first vertex allows the first bolt to pass through and be fixed, ensuring a stable connection between the upper pressure cover 2 and the lower clamping part 1. The second bolt groove fixed on the second vertex opposite to the first vertex provides a fixed position for the bolt, ensuring the stability and safety of the entire structure.

[0047] The line connecting the third vertex 203 and the fourth vertex 204 of the diamond frame is parallel to the wire, so that the wire can extend smoothly under the upper pressure cover, reducing the pressure and friction on the wire. The rubber coating provided on the third and fourth vertices further enhances the interactivity with the wire. The rubber coating is soft and wear-resistant, and can effectively protect the wire. A groove that fits the wire is also provided on the contact surface between the rubber coating and the wire. This design allows the wire to be more firmly fixed inside the upper pressure cover, reducing the possibility of the wire loosening or falling off. At the same time, the groove design can also effectively guide the wire so that it can extend along a predetermined path inside the upper pressure cover, thereby improving the reliability and stability of the entire system.

[0048] Preferably, in some embodiments, the opening direction of the first bolt slot 103 is perpendicular to the opening direction of the second bolt slot 201. The first bolt slot 103 and the second bolt slot lock the first bolt 3011, and the entire structure is more stable.

[0049] Preferably, in some embodiments, the first clamping arm 301 and the second clamping arm 302 are arc-shaped, and rubber packaging is provided on the clamping arms.

[0050] Preferably, in some embodiments, one end of the first clamping arm 101 and the second bolt 3021 are integrally cast, and one end of the second clamping arm 102 is sleeved on the second bolt 3021 .

[0051] The installation status of the anti-drop buckle of this application is shown in the figure below Figure 4 As shown, during installation, Figure 4 As shown, the first clamping arm 101 and the second clamping arm 102 are sleeved on the insulator column between the top platform and the umbrella skirt of the insulator 4, and then the second clamping arm 102 is rotated with the second bolt 3021 as the axis to tighten the space between the two clamping arms. After tightening, the second bolt is rotated upward to make the first bolt 3011 enter the first bolt groove 103 to lock the space between the two clamping arms, so that the lower clamping part 1 is tightly clamped on the insulator 4, so that the installation of the lower clamping part is completed. At this time, the first bolt 3011 is in a vertical state, and the upper pressing plate is rotated with the second bolt 3021 as the axis so that the first bolt 3011 enters the second bolt groove 201 on the diamond frame of the upper pressing plate, and then the nuts on the first bolt and the second bolt are tightened so that the upper pressing plate presses the wire 5, and the installation of the anti-drop buckle is completed. During the whole process, the nuts on the first bolt 3011 and the second bolt 3021 do not need to be unscrewed, and the whole structure is installed as a whole, without redundant independent scattered parts, which is very suitable for high-altitude operations.

[0052] Similarly, during disassembly, first loosen the first nut 3012 on the first bolt 3011, rotate the upper pressure plate 2 with the first bolt 3011 as the axis, so that the first bolt 3011 is rotated out of the first bolt groove 103, and then rotate the second bolt 3021 downward so that the second bolt 3021 is rotated out of the first bolt groove 103, so that the second clamping arm can be rotated and loosened to complete the disassembly.

[0053] The anti-dropout buckle of the present application has no extra independent and scattered parts to be handled during the installation and removal process, which simplifies the operation process and reduces the difficulty and risk of high-altitude operations. At the same time, due to the integrated design of the entire structure, it is not easy to lose parts or install incorrectly during the installation and removal process, which improves the efficiency and safety of installation and removal. In addition, the anti-dropout buckle of the present application has a compact structure, occupies a small space, can adapt to insulators and wires of different specifications, and has strong versatility and adaptability.

[0054] In practical applications, the anti-drop buckle of the present application can effectively prevent the wire from falling off and loosening, thereby improving the safety and stability of the power system. At the same time, since the installation and removal process is simple and quick, the time and cost of high-altitude operations can be reduced, thereby improving work efficiency.

[0055] Although the present application has been described in detail above by means of general description, specific implementation methods and experiments, it is obvious to those skilled in the art that some modifications or improvements may be made to the present application. Therefore, these modifications or improvements made without departing from the spirit of the present application are within the scope of protection claimed in the present application.
