[0002] A surge arrester is an electrical device used to protect electrical equipment from damage caused by lightning overvoltage and operational overvoltage. It is usually connected near the equipment being protected.
[0003] Currently, most surge arresters are fixed with bolts, which can loosen after prolonged use and cause the arrester to separate from the base. Additionally, since surge arresters need to be connected to lines during use, these lines may sway in windy weather. Prolonged swaying can cause the bolts at the connection points to loosen, leading to the line coming off. Utility Model Content

A nut is provided at the bottom of the rotating plate, and a threaded sleeve is slidably connected to the inner wall of the rotating plate. A pressing pad and a limiting plate are fixedly installed at both ends of the threaded sleeve, respectively. A threaded rod is rotatably connected to the inner wall of the rotating plate.
[0006] As a preferred technical solution of this utility model: the second threaded rod is located on the inner wall of the threaded sleeve, and the second threaded rod and the threaded sleeve are threadedly connected, and the limiting plate is in contact with the inner wall of the rotating plate.
[0007] As a preferred technical solution of this utility model: the extrusion pad is located inside the wire placement groove, and the inner wall of the extrusion pad is adapted to the inner wall of the wire placement groove.
[0008] As a preferred technical solution of this utility model: the threaded rod passes through the lifting block, and the threaded rod and the lifting block are threadedly connected.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This securely connected surge arrester, by rotating the rotating head, causes the threaded rod to rotate, which in turn causes the lifting block to move upward, so that the top inclined surface of the lifting block fits against the bottom inclined surface of the pressing block. At this time, the lifting block continues to move upward, pressing the bottom inclined surface of the pressing block, which in turn causes the pressing block to move, causing the connecting column to move, which in turn causes the telescopic head to extend from the inner wall of the lifting plate. At this time, rotating the threaded column causes the threaded column to move, which in turn causes the lifting frame to move, which in turn causes the top lifting plate to move, which in turn causes the lifting plate to move downward, causing the lifting plate to fit against the top of the mounting plate, at which point the mounting plate is fixed.
[0013] 2. The securely connected surge arrester is placed inside the cable tray via the line. Rotating the rotating plate seals the opening of the cable tray. The rotating plate is then fixed with pins and nuts. Rotating the threaded rod two causes the threaded rod two to move through the threaded connection with the threaded sleeve. The movement of the cable tray clamps the line between the compression pad and the cable tray, thus preventing the connection between the line and the surge arrester body from violently swinging when the line is affected by strong winds.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 - Figure 5 A securely connected surge arrester includes a fixed plate 1, a mounting plate 2 on top of the fixed plate 1, a bottom extension shell 3 fixedly mounted on the bottom of the fixed plate 1, a wire placement groove 4 on the outer wall of the fixed plate 1, a surge arrester body 5 fixedly mounted on the top of the mounting plate 2, a threaded column 6 rotatably connected to the inner wall of the bottom extension shell 3, a lifting frame 8 slidably connected to the inner wall of the bottom extension shell 3, a lifting plate 7 fixedly mounted on the top of the lifting frame 8, a telescopic head 9 and a lifting block 15 slidably connected to the inner wall of the lifting plate 7, a rotating head 10 rotatably connected to the inner wall of the lifting plate 7, and a threaded rod 11 fixedly mounted on the bottom of the rotating head 10. One end of a connecting column 14 is fixedly installed on the outer wall of the retractor 9, and the other end of the connecting column 14 is fixedly installed with an extrusion block 12. A partition 16 is fixedly installed on the inner wall of the lifting plate 7, and a spring 13 is provided on the outside of the partition 16. A rotating plate 17 is rotatably connected to the fixed plate 1. A locking block 18 is fixedly installed on the top of the fixed plate 1, and a pin 19 is slidably connected to the inner wall of the locking block 18. A nut 20 is provided at the bottom of the rotating plate 17, and a threaded sleeve 22 is slidably connected to the inner wall of the rotating plate 17. An extrusion pad 21 and a limiting plate 24 are fixedly installed at both ends of the threaded sleeve 22, respectively. A threaded rod 23 is rotatably connected to the inner wall of the rotating plate 17.
[0022] In the above structure, the nut 20 is located directly below the pin 19, so that the bottom of the pin 19 passes through the locking block 18 and the rotating plate 17 to reach the bottom of the rotating plate 17. At this time, the nut 20 is sleeved on the bottom of the pin 19, and the pin 19 is fixed. Rotating the nut 20 causes the nut 20 to move upward through the thread at the bottom of the pin 19, thereby making the nut 20 fit against the bottom of the rotating plate 17, so that the rotating plate 17 and the locking block 18 are fixed together.
[0023] In a preferred embodiment: the second threaded rod 23 is located on the inner wall of the threaded sleeve 22, and the second threaded rod 23 and the threaded sleeve 22 are threadedly connected, and the limiting plate 24 is in contact with the inner wall of the rotating plate 17.
[0024] In the above structure, by rotating the threaded rod 23, the threaded rod 23 drives the threaded sleeve 22 to move through the threaded connection with the threaded sleeve 22. At the same time, the limiting plate 24 is in contact with the inner wall of the rotating plate 17, so that the limiting plate 24 will not rotate when moving, and thus the threaded sleeve 22 will not rotate due to the rotational force of the threaded rod 23 when moving.
[0025] In a preferred embodiment, the compression pad 21 is located inside the wire placement groove 4, and the inner wall of the compression pad 21 is adapted to the inner wall of the wire placement groove 4.
[0026] In the above structure, by placing the wire inside the wire placement groove 4, rotating the rotating plate 17 causes the rotating plate 17 to drive the compression pad 21 to rotate, so that the rotating plate 17 seals the opening of the wire placement groove 4, and the wire is located between the compression pad 21 and the wire placement groove 4. At this time, the wire is clamped between the compression pad 21 and the wire placement groove 4 by the movement of the wire placement groove 4.
[0027] In a preferred embodiment: the threaded rod 11 passes through the lifting block 15, and the threaded rod 11 and the lifting block 15 are threadedly connected.
[0028] In the above structure, by rotating the rotating head 10, the rotating head 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the lifting block 15 to move up and down through the threaded connection with the lifting block 15. At the same time, the lifting block 15 is limited by the fit between the lifting block 15 and the lifting plate 7, so that the lifting block 15 will not tilt.
[0029] In a preferred embodiment, the top of the lifting block 15 and the bottom of the pressing block 12 are both inclined surfaces, and the top of the lifting block 15 is parallel to the bottom of the pressing block 12.
[0030] In the above structure, the upward movement of the lifting block 15 causes the top inclined surface of the lifting block 15 to fit against the bottom inclined surface of the pressing block 12. At this time, the lifting block 15 continues to move upward, thereby pressing the bottom inclined surface of the pressing block 12 through the top inclined surface, which in turn causes the pressing block 12 to move, which in turn causes the connecting column 14 to move, which in turn causes the connecting column 14 to drive the telescopic head 9 to extend out from the inner wall of the lifting plate 7.
[0031] In a preferred embodiment: the shape of the lifting plate 7 is adapted to the shape of the mounting plate 2, and the lifting frame 8 is penetrated by the threaded post 6, and the lifting frame 8 and the threaded post 6 are threadedly connected.
[0032] In the above structure, by rotating the threaded column 6, the threaded column 6 drives the lifting frame 8 to move through the threaded connection with the lifting frame 8, which in turn drives the top lifting plate 7 to move, and the lifting plate 7 slides on the inner wall of the mounting plate 2.
[0033] Working Principle: The equipment requires installation. Fixing plate 1 to the installation point, aligning the inner wall of mounting plate 2 with the lifting plate 7, and fitting mounting plate 2 onto the outer wall of the lifting plate 7. Moving mounting plate 2 until it is flush with fixing plate 1, rotating the rotating head 10 causes the threaded rod 11 to rotate. This threaded rod 11, through its threaded connection with the lifting block 15, moves the lifting block 15 upwards, causing its top inclined surface to align with the bottom inclined surface of the pressing block 12. The lifting block 15 continues to move upwards, pressing the bottom inclined surface of the pressing block 12 with its top inclined surface, causing the pressing block 12 to move. This causes the pressing block 12 to move the connecting column 14, which in turn causes the telescopic head 9 to extend from the inner wall of the lifting plate 7. The rotating head 10 then rotates... The threaded column 6, through its threaded connection with the lifting frame 8, causes the lifting frame 8 to move, which in turn causes the lifting frame 8 to move the top lifting plate 7, which in turn causes the lifting plate 7 to move the telescopic head 9 downward, so that the lifting plate 7 fits against the top of the mounting plate 2. At this time, the mounting plate 2 is fixed. After the wiring is connected, the wiring is placed inside the wiring trough 4. Then, the rotating plate 17 is rotated to seal the opening of the wiring trough 4. The rotating plate 17 is fixed by the pin 19 and the nut 20. Then, the threaded rod 23 is rotated, which in turn causes the threaded sleeve 22 to move through its threaded connection with the threaded sleeve 22. The movement of the wiring trough 4 clamps the wiring between the compression pad 21 and the wiring trough 4, so that the connection between the wiring and the surge arrester body 5 will not be violently swayed when the wiring is affected by strong winds.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
