The embodiment of the utility model is given for example and description, and is not exhaustive or limit the utility model to the disclosed form. Many modifications and changes are obvious to those skilled in the art.

[0020] Embodiment:

[0021] Please refer to Figure 1 - Figure 5This utility model provides a technical solution: a lightweight and high-strength equalizing ring for ultra-high voltage applications, comprising: a support structure 1, with a pressure ring structure 2 slidably connected to the inner wall of the support structure 1; the support structure 1 includes a fixed frame 11, with threaded rods 12 symmetrically threadedly connected to the inner wall of the fixed frame 11, a clamping block 13 rotatably connected to the outer wall of the threaded rod 12, an anti-slip pad 14 fixedly connected to the outer wall of the clamping block 13, a support rod 15 symmetrically fixedly connected to the outer wall of the side of the fixed frame 11, a connecting ring 16 fixedly connected to the outer wall of the bottom of the support rod 15, a fixed block 17 symmetrically slidably connected to the inner wall of the connecting ring 16, a pull plate 18 fixedly connected to the outer wall of the fixed block 17, a sliding rod 19 symmetrically slidably connected to the inner wall of the pull plate 18, and a compression spring 191 fixedly connected to the outer wall of the sliding rod 19.

[0022] A knob is fixedly connected to the outer wall of the threaded rod 12 on the side away from the clamping block 13. The outer wall of the clamping block 13 is slidably connected to the inner wall of the fixed frame 11. When the knob on the threaded rod 12 is rotated, the clamping block 13 will slide along the inner wall of the fixed frame 11 in opposite directions or in opposite directions because the threaded rod 12 is threadedly connected to the inner wall of the fixed frame 11.

[0023] The outer wall of the slide rod 19 away from the compression spring 191 is fixedly connected to the outer wall of the connecting ring 16. The outer wall of the compression spring 191 away from the slide rod 19 is fixedly connected to the outer wall of the pull plate 18. The compression spring 191 is located outside the slide rod 19. Pulling the pull plate 18 causes the pull plate 18 to slide away from the connecting ring 16 along the direction of the slide rod 19, thereby compressing and storing the compression spring 191.

[0024] The pressure ring structure 2 includes a ring body 21. A limit ring 22 is symmetrically fixedly connected to the outer wall of the ring body 21. A fixing groove 23 is symmetrically opened on the outer wall of the ring body 21. A pressure-resistant plate 24 is fixedly connected to the inner wall of the ring body 21. A pressure-resistant frame 25 is fixedly connected to the outer wall of the ring body 21. The pressure-resistant frame 25 can effectively enhance the overall bending and torsional resistance of the ring body 21.

[0025] The pressure-resistant plates 24 are arranged in a ring array along the central point of the ring body 21. The pressure-resistant plates 24 can share the pressure borne by the ring body 21, further enhancing the pressure resistance of the ring body 21.

[0026] The inner wall of the connecting ring 16 is slidably connected to the outer wall of the ring body 21, and the ring body 21 is symmetrically arranged inside the connecting ring 16. The outer wall of the connecting ring 16 is in contact with the outer wall of the limiting ring 22. The outer wall of the fixing block 17 is slidably connected to the inner wall of the fixing groove 23. The symmetrical ring body 21 is inserted into the inner wall of the connecting ring 16 from both sides of the bottom of the support rod 15. As the ring body 21 slides along the inner wall of the connecting ring 16, it will contact the inclined surface on the fixing block 17 on its inner wall. By continuing to press and slide inward, the fixing block 17 is pressed and slides outward along the inner wall of the connecting ring 16 through the action of its inclined surface. When the outer wall of the connecting ring 16 contacts the limiting ring 22 on the outer wall of the ring body 21, the fixing groove 23 on the ring body 21 is also aligned with the fixing block 17 on the inner wall of the connecting ring 16. Under the elastic force of the compression spring 191, the pull plate 18 is pushed, thereby driving the fixing block 17 to slide into the fixing groove 23, realizing the connection between the pressure ring structure 2 and the support structure 1.

[0027] Working principle: First, during installation, by rotating the knob on the threaded rod 12 in the support structure 1, since the threaded rod 12 is threadedly connected to the inner wall of the fixed frame 11, the rotation will cause the clamping block 13 to slide along the inner wall of the fixed frame 11 in opposite directions, which can clamp the high-voltage equipment. The anti-slip pad 14 on the outer wall of the clamping block 13 can increase the friction between it and the high-voltage equipment to be installed, thereby firmly installing the entire support structure 1 on the corresponding equipment.

[0028] After the support structure 1 is installed, the pressure ring structure 2 is connected. The symmetrical ring 21 is inserted into the inner wall of the connecting ring 16 from both sides of the bottom of the support rod 15. As the ring 21 slides along the inner wall of the connecting ring 16, it will contact the inclined surface on the fixing block 17 on its inner wall. By continuing to press and slide inward, the fixing block 17 is pressed and slides outward along the inner wall of the connecting ring 16 by the action of its inclined surface. At the same time, the pull plate 18 also slides outward along the slide rod 19. Because of the outward movement of the pull plate 18, the compression spring 191 is compressed and stores force. When the outer wall of the connecting ring 16 is in contact with the limiting ring 22 on the outer wall of the ring 21... When in contact, the fixing groove 23 on the ring 21 is aligned with the fixing block 17 on the inner wall of the connecting ring 16. Under the elastic force of the compression spring 191, the pull plate 18 is pushed, which in turn drives the fixing block 17 to slide into the fixing groove 23, thus realizing the connection between the pressure ring structure 2 and the support structure 1. Conversely, pulling the pull plate 18 causes it to slide away from the connecting ring 16 along the direction of the slide rod 19. The sliding of the pull plate 18 will cause the fixing block 17 to move out of the fixing groove 23 of the ring 21, thereby releasing the fixed connection between the connecting ring 16 and the pressure ring structure 2. Then, the ring 21 can be pulled out of the connecting ring 16 to complete the disassembly.

[0029] Meanwhile, the compression frame 25 on the outer wall of the ring 21 can effectively enhance the overall bending and torsional resistance of the ring 21 and improve its structural stability. The compression plates 24 arranged in a ring array along the central axis of the ring 21 can share the pressure borne by the ring 21 and further enhance the compression resistance of the ring 21.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
