Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically to an insulator used in overhead power transmission and distribution lines. Background Technology

[0002] The existing Chinese patent document CN219393063U discloses a through-hole disc insulator, which includes: a groove on the surface of the insulator body, a positioning plate in the groove, a retaining plate on the surface of the insulator body, a traction plate passing through the side wall of the retaining plate, and a flange fitted on the surface of the insulator body. The beneficial effect is that, in the through-hole disc insulator proposed in this utility model, when in use, the traction plate is first pulled to move the positioning plate into the groove, then the flange is fitted onto the insulator body, and then the traction plate is released. The positioning plate is reset by the elasticity of the spring, so that the positioning plate and the boss fix the flange surface. This avoids the problem of the flange falling off the insulator disc due to the traditional method of fixing the flange and the insulator disc with glue, which is subject to huge radial pressure during use.

[0003] However, in the above-mentioned solutions and existing technologies, the transmission and distribution lines are placed on the top of the insulator and fixed with clamps to achieve the overhead installation of the transmission and distribution lines. During the operation, auxiliary tools are needed to tighten the screws on the clamps to fix the transmission and distribution lines, which is inconvenient and affects the efficiency of the transmission and distribution line installation. Improvements and optimizations are needed.

[0004] Therefore, this utility model proposes an insulator for overhead power transmission and distribution lines to solve the above problems. Utility Model Content

The rotating column and the lever plate are inserted into the straight groove, and the lever plate is engaged with the boss plate.

[0012] Preferably, the rotating plate in the auxiliary component is fixedly mounted on the peripheral wall of the rotating column, and the rotating plate is movably mounted in the movable groove. A square groove is opened on the bottom wall of the movable groove, a hollow groove is opened in the boss, and a paddle groove is opened on the side wall of the hollow groove.

[0013] Preferably, a limiting plate is movably engaged in the slot, a spring is provided on the side end of the limiting plate, a connecting column is fixedly provided on the side wall of the limiting plate, a positioning plate is fixedly provided through the square slot at the end of the connecting column, the positioning plate is engaged with the square slot, the positioning plate is engaged with the rotating plate, and a paddle is fixedly provided on the side wall of the limiting plate, the paddle is movably disposed in the paddle slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] After the main body of the power transmission and distribution line is inserted into the mounting groove and placed on the arc surface of the arc-shaped pad, the cover plate is rotated to press the main body of the power transmission and distribution line into contact with the anti-slip ridges on the arc surface of the arc-shaped pad. At the same time, the rotating column and the lever plate are inserted into the straight groove. Then, the lever plate is rotated to make the lever plate engage with the convex plate and limit the cover plate. The compressed spring returns to its original position and pushes the limit plate to move, which drives the positioning plate to move upward so that its end wall engages with the rotating plate, thereby fixing the position of the lever plate. This allows the main body of the power transmission and distribution line to be stably erected on the insulator body for overhead power transmission and distribution lines. The operation is simple and quick, without the need for auxiliary tools, which improves the efficiency of power transmission and distribution line erection. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-4 The present invention provides the following two preferred embodiments:

[0023] Example 1: An insulator for overhead power transmission and distribution lines, comprising: an insulator body 1, with a mounting platform 2 fixedly disposed on the upper end of the insulator body 1, and a mounting groove 3 formed on the upper end of the mounting platform 2; a cover plate 4, rotatably disposed on the mounting platform 2, the mounting platform 2 being provided with a fixing component and an auxiliary component for mounting the power transmission and distribution line body 5; an arc-shaped pad 6 in the fixing component being fixedly disposed on the bottom wall of the mounting groove 3, the arc surface of the arc pad 6 being provided with anti-slip ridges 7, the power transmission and distribution line body 5 being engaged and fitted with the arc pad 6. The cover plate 4 has an arc-shaped slot 8, which engages with the main body 5 of the power transmission and distribution cable. A protruding plate 9 is fixedly installed on the side wall of the cover plate 4, and a straight groove 10 is fixedly installed on the side wall of the protruding plate 9. A boss 11 is fixedly installed on the side wall of the mounting platform 2, and a movable groove 12 is opened on the side wall of the boss 11. A rotating column 13 is rotatably installed on the bottom wall of the movable groove 12. The end of the rotating column 13 passes through the boss 11, and a lever 14 is symmetrically fixed on the peripheral wall of the end of the rotating column 13. The rotating column 13 and the lever 14 are inserted into the straight groove 10, and the lever 14 is engaged with the protruding plate 9.

[0024] In use, lift the cover plate 4 to expose the mounting groove 3, insert the main body 5 of the power transmission and distribution line into the mounting groove 3, and place it on the arc surface of the arc-shaped pad 6. Rotate the cover plate 4 until the arc-shaped groove 8 engages with the main body 5 of the power transmission and distribution line. At this time, the cover plate 4 presses the main body 5 of the power transmission and distribution line so that the main body 5 of the power transmission and distribution line is in contact with the anti-slip ridges 7 on the arc surface of the arc-shaped pad 6, which plays an anti-slip and fixing role. At the same time, the rotating column 13 and the lever 14 are inserted into the straight groove 10. Then, rotate the lever 14 so that the lever 14 engages with the convex plate 9 and fixes the position of the lever 14. This realizes that the main body 5 of the power transmission and distribution line is stably erected on the insulator body 1 for overhead power transmission and distribution lines. The operation is simple and quick, without the need for auxiliary tools, which improves the efficiency of power transmission and distribution line erection.

[0025] Example 2: Based on Example 1, the rotating plate 15 in the auxiliary component is fixedly mounted on the peripheral wall of the rotating column 13. The rotating plate 15 is movably mounted in the movable groove 12. A square groove 16 is opened on the bottom wall of the movable groove 12, and a hollow groove 17 is opened in the boss 11. A paddle groove 18 is opened on the side wall of the hollow groove 17. A limiting plate 19 is movably engaged in the hollow groove 17. A spring 20 is provided on the side end of the limiting plate 19. A connecting column 21 is fixedly mounted on the side wall of the limiting plate 19. A positioning plate 22 is fixedly mounted through the square groove 16 at the end of the connecting column 21. The positioning plate 22 is engaged with the square groove 16 and the rotating plate 15. A paddle 23 is fixedly mounted on the side wall of the limiting plate 19 and is movably mounted in the paddle groove 18.

[0026] In use, when the main body 5 of the power transmission and distribution line is placed on the arc-shaped pad 6 and the cover plate 4 is covered, the rotating plate 15 and the side wall of the positioning plate 22 are engaged to fix the position of the rotating column 13, so that the rotating column 13 and the dial plate 14 can be inserted into the straight groove 10. After the cover plate 4 presses the main body 5 of the power transmission and distribution line, the dial plate 23 moves down along the dial plate groove 18, which drives the limiting plate 19 to move down and compress the spring 20 until the positioning plate 22 is embedded in the square groove 16. Then the rotating plate 15 is unlocked. Then the dial plate 14 is rotated so that the dial plate 14 and the protruding plate 9 are engaged to fix the position of the cover plate 4, and the rotating plate 15 is engaged with the side wall of the movable groove 12. The dial plate 23 is released, the spring 20 is reset and pushes the limiting plate 19 to move, which in turn makes the positioning plate 22 move upward. At this time, the end wall of the positioning plate 22 is engaged with the rotating plate 15 to fix the position of the rotating column 13 again, and then fixes the position of the dial plate 14 to limit the cover plate 4. The operation is simple and further ensures the stability of the erection of the main body 5 of the power transmission and distribution line.
