[0002] A surge arrester is an electrical device used to protect electrical equipment from the hazards of high transient overvoltages during lightning strikes, and to limit the duration and amplitude of follow current. It is easy to install and is usually fixed with nuts.

[0003] For example, CN202220394842.X discloses a surge arrester fixing device, including a base. At least three fixing blocks are fixedly connected to the upper surface of the base. A first mounting groove is opened on one side of each of the at least three fixing blocks. A fixing mechanism is slidably connected inside each of the three first mounting grooves. A fixing seat for installing a surge arrester is slidably connected to one end of each of the at least three fixing mechanisms away from the first mounting grooves. An installation mechanism is provided on the outer surface of the support column.

[0004] It has the following disadvantages:

[0005] 1. The bottom of the fixing mechanism is slidably connected to the mounting groove inside the fixing block. The top of the fixing mechanism is installed inside the fixing seat. The mounting mechanism is installed on the top of the fixing block. The fixing mechanism, fixing block and mounting mechanism are fixed with nuts. The installation and disassembly process is complicated and takes a long time.

[0006] 2. Nuts for fixing are installed on both the fixing mechanism and the mounting slot. The nuts are not easy to remove when the product has been used for a long time. Utility Model Content

[0007] To address the issues raised in the background art, such as the complex and time-consuming installation and disassembly process involving a mounting mechanism mounted on top of a fixing block, with the fixing mechanism, fixing block, and mounting mechanism secured by nuts, and the inconvenience of disassembling nuts after prolonged use, the following solutions are proposed.

[0008] This utility model provides the following technical solution: a surge arrester fixing device that is easy to install, comprising a surge arrester body, characterized in that: a sliding protrusion is installed at the bottom of the surge arrester body, an L-shaped fixing plate for fixing the surge arrester is installed at the bottom of the protrusion, a rotating block for fixing rotation is installed inside the L-shaped fixing plate, a top block for left and right movement is installed on one side of the rotating block, a base is installed between the L-shaped fixing plate and the surge arrester body, a fixing groove for fixing the surge arrester body is opened at one end of the base near the surge arrester body, and a fixing block for positioning is installed at one end of the fixing groove.

[0009] Furthermore, the surface of the rotating block is provided with shallow and deep grooves for rotation.

[0010] Furthermore, the top block is provided with limiting blocks at both the upper and lower ends of the end near the shallow groove to restrict the top block.

[0029] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0030] Please see Figure 1-3 This utility model provides an easy-to-install surge arrester fixing device, including a surge arrester body 1. A sliding protrusion 3 is installed on the bottom of the surge arrester body 1. The protrusion 3 is cuboid in shape and its length is flush with the bottom of the surge arrester body 1. An L-shaped fixing plate 2 for fixing the surge arrester is installed on the bottom of the protrusion 3. The L-shaped fixing plate 2 can fix the surge arrester body 1 to the base 10. A positioning block 22 for fixing the L-shaped fixing plate 2 is installed on one side of the surge arrester body 1. A rotating block 23 is installed on the upper end of the L-shaped fixing plate 2 near the positioning block 22. The rotating block 23 is installed inside the positioning block 22 on the surge arrester body 1. The rotating block 23 can move the L-shaped fixing plate 2 on the surge arrester body 1 up and down.

[0031] Please see Figure 3-10The L-shaped fixing plate 2 contains a rotating block 4 for fixing rotation. The rotating block 4 is cylindrical. A rotating column 20, also cylindrical, is installed at the bottom of the rotating block 4 to drive its rotation. The rotating column 20 passes through the rotating block 4. A top block 5, cylindrical in shape, is installed on one side of the rotating block 4 for left and right movement. One end of the top block 5 near the rotating block 4 is rounded, and the other end is flat. The rounded end can move on the surface of the deep groove 9 and shallow groove 8 on the surface of the rotating block 4. When the L-shaped fixing plate 2 rotates, it drives the rotating block 4 to rotate, which in turn drives the top block 5 to move left and right. A base 10 is installed between the L-shaped fixing plate 2 and the surge arrester body 1. The surface of the base 10 has a groove 11 for the movement of the protrusion 3. The internal shape of the groove 11 is consistent with the shape of the protrusion 3. A fixing groove 12 for fixing the surge arrester body 1 is provided at one end of the base 10 near the L-shaped fixing plate 2. The fixing groove 12 is rectangular. A fixing block 13 for positioning is installed at one end of the fixing groove 12. For reinforcement, the surface of the rotating block 4 is provided with shallow grooves 8 and deep grooves 9 for rotation. Limiting blocks 7 are respectively installed at the upper and lower ends of the top block 5 near the shallow groove 8 to restrict its movement. The limiting blocks 7 are cuboid in shape, with one end fixed to the L-shaped fixing plate 2 and the other end near the top block 5. Springs A6 are installed around the top block 5 to drive its movement. One end of the spring A6 is fixed to the L-shaped fixing plate 2, and the other end is fixed to the surface of the top block 5. When the rotating block 4 rotates, the top block 5 moves within the deep groove 9 and shallow groove 9. When the surface of groove 8 moves, the top block 5 drives the spring A6 to move left and right. When the rotating block 4 rotates, the round end of the top block 5 turns to the shallow groove 8, and the flat end can push the spring B15 inside the sliding plate 21 inside the fixed deep groove 12 into the inside. The rotating block 4 can pass through the L-shaped fixed plate 2 and push to the bottom of the fixed deep groove 12. In this way, the L-shaped fixed plate 2 can be pushed out of the fixed deep groove 12. When it turns to the deep groove 9, the spring A6 on the periphery of the top block 5 pushes the top block 5 to one end of the limit block 7. At this time, the flat end of the top block 5 will retract the top block 5 that was exposed outside.

[0032] A positioning plate 18 for fixing the L-shaped fixing plate 2 is installed above the fixing block 13. The shape of the positioning plate 18 is the same as the size of the opening on the fixing groove 12 inside the L-shaped fixing plate 2. When the L-shaped fixing plate 2 is placed inside the fixing groove 12, the positioning plate 18 is embedded in the opening and can play a fixing role. A sliding plate 21 for pressing against the spring B15 is installed below the positioning plate 18. The sliding plate 21 can push the spring B15 inward and press against the rest of the L-shaped fixing plate 2. A sliding plate 14 for sliding is installed on the inner side of the positioning plate 18. The slide plate 14 is rectangular. The positioning plate 18 is fixed to one end of the slide plate 14. A groove 19 for sliding the slide plate 14 is installed under the slide plate 14. A slide rail 16 for sliding the groove 19 is installed under the limiting plate 17. The slide plate 14 moves inside the limiting plate 17. A spring B15 for driving the sliding plate 21 is installed under the limiting plate 17. When the L-shaped fixing plate 2 enters the fixing deep groove 12, the positioning plate 18 is embedded in the tiger's mouth inside the L-shaped fixing plate 2. One end of the L-shaped fixing plate 2 pushes the spring B15 into the fixing deep groove 12.

[0033] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
