[0002] A power insulator is a device installed between conductors at different potentials or between a conductor and a grounding member that can withstand voltage and mechanical stress. There are many types of insulators with various shapes. Although the structures and appearances of different types of insulators vary greatly, they are all composed of two main parts: an insulating part and a connection structure. Most of the existing connection structures of power insulators are composed of simple screws and bolts. Although the installation purpose can be achieved, their usage functions and ranges are single. Among them, most obviously, during actual operations, when we need to adjust the installation height of the power insulator and the support frame, it is found that the existing connection structure of the power insulator cannot achieve this, and additional padding components need to be added, which delays the installation efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 、 Figure 2 A power insulator for a power distribution system includes a power insulator 1. A composite screw member 2 is installed at the bottom of the power insulator 1. The interior of the composite screw member 2 includes a screw body 21, and a slide groove 22 and a threaded hole group 23 are respectively opened inside one side of the screw body 21. The interior of the threaded hole group 23 includes multiple threaded holes, and the specific number is not less than two. The multiple threaded holes can realize the installation conditions of multiple installation points. The threaded holes inside the threaded hole group 23 are connected with the interior of the slide groove 22. The composite screw member 2 provides displacement adjustment installation and provides clearance space and reset locking and fixing conditions for the subsequently set components, and the surface of the top of the composite screw member 2 is fixedly sleeved with a positioning plate 3.

[0020] See also Figure 3 The surface of the bottom of the composite screw member 2 is threadedly connected with a nut 4, and the middle part of the composite screw member 2 is movably sleeved with a movable mounting sleeve member 5, the interior of the movable mounting sleeve member 5 includes a sleeve body 51, and the sleeve body 51 is movably sleeved on the surface of the middle part of the composite screw member 2, and a guide block 52 is fixedly sleeved inside one side of the sleeve body 51, and the guide block 52 is clamped inside the slide groove 22. The guide block 52 cooperates with the slide groove 22 to provide guidance and anti-deflection constraints for the subsequent movement of the sleeve body 51, fully improving the reliability of the movement and adjustment of the sleeve body 51, and the guide block 52 and the sleeve body are fixed. A clearance hole 53 is commonly opened on one side of the body 51, and a screw 7 is movably sleeved inside the clearance hole 53, and one end of the screw 7 is threadedly connected to the corresponding threaded hole inside the threaded hole group 23. After the above-mentioned composite screw member 2, nut 4, movable mounting sleeve 5, and screw 7 are assembled with each other, a flexible and adjustable mounting mechanism can be formed. In the subsequent specific use of the power insulator 1, the installation distance between the top of the power insulator 1 and the conductor can be adaptively adjusted according to actual needs while ensuring a stable and reliable installation, thereby expanding the use function and scope of the overall device.

[0021] See also Figure 4A buffer component 6 is installed between the top surface of the movable mounting sleeve 5 and the bottom surface of the positioning disk 3. The interior of the buffer component 6 includes a positioning sleeve 61, and the bottom of the positioning sleeve 61 is fixedly connected to the top surface of the sleeve body 51. A T-shaped rod 62 is clamped inside the positioning sleeve 61, and a compression spring 63 is fixedly connected between the bottom surface of the T-shaped rod 62 and the top surface of the sleeve body 51. The compression spring 63 can achieve elastic deformation buffering and energy dissipation for the vibration impact of the subsequent overall device. A buffer pad 64 is fixedly connected to the top of the T-shaped rod 62. The top surface of the buffer pad 64 is movably connected to the bottom surface of the positioning disk 3, and the buffer pad 64 is specifically made of elastic rubber material. The T-shaped rod 62 and the buffer pad 64 can achieve displacement activity buffering and energy dissipation for the vibration impact of the subsequent overall device.

[0022] Working principle: When in use, one end of the composite screw member 2 is passed through the clearance space of the existing mounting frame, and then the nut 4 is threadedly connected to the surface of the bottom of the composite screw member 2. Then, according to actual use requirements, the installation height of the power insulator 1 is adjusted. The specific operation is as follows: Example

[0023] After the screw 7 is screwed down and the bottom surface of the movable mounting sleeve 5 and the composite screw member 2 is disengaged, the movable mounting sleeve 5 is moved upward to expand the movable space of the composite screw member 2. After completion, the entire device is moved downward to make the bottom surface of the movable mounting sleeve 5 after the position adjustment fit with the top surface of the existing mounting frame. The screw 7 is then compositely locked with the corresponding threaded holes inside the threaded hole group 23 to achieve the effect of lowering the height adjustment of the power insulator 1. The nut 4 is then turned until it fits with the bottom surface of the existing mounting frame to achieve fixed installation. At this time, the compression spring 63 and the buffer pad 64 T-rod 62 inside the buffer component 6 will be adaptively displaced and adjusted. Subsequently, when the entire device is subjected to vibration impact, the T-rod 62 and the buffer pad 64 will be displaced and buffered to dissipate energy, and the compression spring 63 will elastically deform and buffer to dissipate energy. Example

[0024] After the nut 4 is threadedly connected to the bottom surface of the composite screw member 2, move the entire device upward until the top surface of the nut 4 first fits against the bottom surface of the existing mounting bracket. Then, turn the screw 7 to disengage the screw 7 from the movable mounting plate member 5 and the composite screw member 2. Next, move the movable mounting plate member 5 downward so that the bottom surface of the movable mounting plate member 5 fits against the top surface of the existing mounting bracket. Subsequently, compound-lock the screw 7 with the corresponding threaded hole inside the threaded hole group 23. Thus, the height adjustment effect of the lifting electrical insulator 1 is achieved. Then, turn the nut 4 to lock it. After completion, tighten the installation. At this time, the compression spring 63, the buffer pad 64, and the T-shaped rod 62 inside the buffer member 6 will adaptively adjust their displacements. Subsequently, when the entire device is subjected to vibration and shock, the T-shaped rod 62 and the buffer pad 64 displace and buffer to dissipate energy, and the compression spring 63 elastically deforms to buffer and dissipate energy.
