[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1, please refer to Figure 1-4The utility model provides a technical solution: a high-voltage line column porcelain insulator, including a base 1, two notches 102 are provided near the edge of the top of the base 1, and limiting columns 111 are fixedly embedded on both sides of the inner wall of one of the notches 102, and double-threaded rods 110 are movably embedded on both sides of the inner wall of the other notch 102, and a knob 109 is movably connected to one side of the outer surface of the base 1, and one side of the outer surface of the knob 109 is fixedly connected to one end of the double-threaded rod 110, and two square plates 101 are fixedly connected to both sides of the outer surface of the base 1, and a threaded hole 103 is provided on one side of the outer surface of the two square plates 101, and the outer surface of the base 1 is fixed Two fixed plates 104 are connected, and the outer surface of the double-threaded rod 110 is threadedly connected to two sliders 112, and the tops of the two sliders 112 are fixedly connected with arc-shaped clamping plates 107 near the edges, and the bottoms of the arc-shaped clamping plates 107 are fixedly connected with sliders 106 near the edges, and the inner movable sleeve of the sliders 106 is arranged on the outer surface of the limiting column 111, and the top center of the base 1 is fixedly connected with a hollow column 2, and one side of the outer surface of the hollow column 2 is provided with a threaded hole 205, and the inner wall of the threaded hole 205 is threadedly connected with the insulator body 105, and the inner walls of the two arc-shaped clamping plates 107 are fixedly connected with a plurality of anti-slip pads 108.

[0032] In this embodiment, the bottom connector of the insulator body 105 is connected to the hollow column 2 through the threaded hole 205. In order to prevent the insulator body 105 from shaking left and right, the staff starts to turn the knob 109, and the knob 109 starts to rotate forward. The knob 109 rotates while driving the double threaded rod 110 to rotate forward. The force generated by the forward rotation of the double threaded rod 110 drives the sliders 112 on both sides to start to move closer to the middle. The sliders 112 on both sides move while driving the two arc-shaped clamping plates 107 to move closer to the middle. At the same time, the slider 106 below the arc-shaped clamping plate 107 is on the limit column. By continuously rotating the knob 109, the two arc-shaped clamping plates 107 gradually move toward the insulator body 105, and gradually firmly clamp the insulator body 105, so as to prevent the insulator body 105 from shaking left and right due to wind, thereby achieving better stabilization of the insulator body 105, preventing the insulator body 105 from shaking left and right due to strong wind, improving its stability, avoiding the insulator body 105 from being damaged by wind, and improving the service life of the insulator body 105.

[0033] Embodiment 2, as Figure 1-4As shown, multiple anti-slip pads 108 are fixedly connected to the inner walls of the two arc-shaped clamping plates 107, multiple fixed columns 201 are fixedly connected to the top of the base 1 near the center, multiple dampers 203 are fixedly connected to the top of the base 1 near the center, multiple springs 202 are fixedly connected to the top of the base 1 near the center, one end of the multiple springs 202 is fixedly connected to a circular plate 204, and one side of the outer surface of the circular plate 204 is fixedly connected to one end of the damper 203.

[0034] In this embodiment, in order to prevent the insulator body 105 from hitting the base 1 and being damaged, when the staff is installing the insulator body 105, the bottom edge of the insulator body 105 will first contact the multiple circular plates 204, and the multiple circular plates 204 will begin to be affected by the gravity of the insulator body 105. The circular plates 204 generate a buffering force through the spring 202 and the damper 203, so as to disperse the weight of the bottom of the insulator body 105, thereby avoiding the bottom of the insulator body 105 from colliding with the base 1 during installation, preventing excessive manual force from causing the high-voltage insulator to hit the base 1, causing damage to the insulator, and improving the quality of the high-voltage insulator.

[0035] Working principle: when in use, the staff first connects the bottom connector of the insulator body 105 to the hollow column 2 through the threaded hole 205. In order to prevent the insulator body 105 from shaking left and right, the staff starts to turn the knob 109, and the knob 109 starts to rotate forward. When the knob 109 rotates, it drives the double-threaded rod 110 to rotate forward. The force generated by the forward rotation of the double-threaded rod 110 drives the sliders 112 on both sides to start to move toward the middle. When the sliders 112 on both sides move, they respectively drive the two arc-shaped clamping plates 107 to move toward the middle. At the same time, the slider 106 under the arc-shaped clamping plate 107 moves on the limit column 111, and the limit column 111 limits it to prevent the two arc-shaped clamping plates 107 from idling. By continuously turning the knob 109, the two arc-shaped clamping plates 107 gradually move toward the insulator body 105 and gradually clamp the insulator body 105 firmly, so as to prevent the insulator body 105 from being affected by wind force. The left and right shaking is affected, thereby achieving better stabilization of the insulator body 105, preventing the insulator body 105 from shaking left and right due to strong winds, improving its stability, avoiding the insulator body 105 from being blown away and damaged by the wind, and improving the service life of the insulator body 105. During installation, since the high-voltage insulator body 105 is very heavy, in order to avoid the insulator body 105 from hitting the base 1 and being damaged, when the staff installs the insulator body 105, the bottom edge of the insulator body 105 will first contact the multiple circular plates 204, and the multiple circular plates 204 begin to be affected by the gravity of the insulator body 105. The circular plates 204 generate buffering force through the spring 202 and the damper 203, thereby dispersing the weight of the bottom of the insulator body 105, thereby avoiding the bottom of the insulator body 105 from colliding with the base 1 during installation, preventing excessive manual force from causing the high-voltage insulator to hit the base 1, causing damage to the insulator, and improving the quality of the high-voltage insulator.
