Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-6 As shown, this utility model provides a technical solution: a detachable surge arrester, including a surge arrester body 1 and a mounting base 2. A mounting plate 3 is provided on the side of the mounting base 2, and a fixing bolt 4 is threadedly connected to the inside of the mounting plate 3. A mounting box 5 is fixedly mounted on the surface of the mounting base 2. A clamping plate 6 is slidably connected to the inner side of the mounting box 5, and a connecting block 7 is fixedly connected to the lower surface of the clamping plate 6. A bidirectional lead screw 8 is rotatably connected inside the mounting box 5, and a rotating head 9 is fixedly mounted at one end of the bidirectional lead screw 8. A limit hole 10 is formed on the surface of the rotating head 9. A fixing bolt 4 is fixedly mounted on the side of the mounting box 5. Fixed plate 11, with a limiting rod 12 slidably connected inside the fixed plate 11, a limiting plate 13 fixedly installed on the surface of the limiting rod 12, a tension spring 14 sleeved on the surface of the limiting rod 12, an anti-slip pad 15 provided on the side of the clamping plate 6, the anti-slip pad 15 being made of natural rubber, a two-way screw 8 being threadedly connected to the connecting block 7, a sliding connection between the connecting block 7 and the mounting box 5, a sliding connection between the limiting rod 12 and the limiting hole 10, one end of the tension spring 14 being fixedly connected to the side of the limiting plate 13, and the other end of the tension spring 14 being fixedly connected to the side of the fixed plate 11.

[0025] In this embodiment, rotating the rotating head 9 causes the bidirectional lead screw 8 to rotate, which in turn causes the clamping plates 6 on both sides to move relative to or away from each other, thereby clamping or releasing the surge arrester body 1. This facilitates the installation and disassembly of the surge arrester body 1, improving work efficiency. Furthermore, the clamping plates 6 are provided with anti-slip pads made of natural rubber, which increases friction, ensures the stability of the clamping of the surge arrester body 1, and prevents damage to the surge arrester body 1. The limiting rod 12 is inserted into the limiting hole 10 under the action of the tension spring 14, which can limit the rotating head 9 and prevent the clamping plates 6 from loosening due to accidental rotation of the bidirectional lead screw 8, thus ensuring the reliability of the clamping of the surge arrester body 1.

[0026] Example 2: As Figures 1-6 As shown, the mounting base 2 has a sliding groove 16 on its side, the mounting plate 3 has a slider 17 fixedly connected to its side, the mounting plate 3 has a positioning rod 18 threadedly connected to its side, the mounting base 2 has a positioning hole 19 on its side, the slider 17 is slidably connected to the sliding groove 16, and the positioning rod 18 is threadedly connected to the positioning hole 19.

[0027] In this embodiment, the slider 17 is slidably connected to the groove 16 on the side of the mounting base 2, and the positioning rod 18 is threadedly connected to the positioning hole 19. This structure allows the mounting plate 3 to be adjusted within a certain range, making it easy to adapt to different installation environments and requirements, and further improving the installation flexibility and versatility of the detachable surge arrester.

[0028] The working principle of the embodiment is as follows: in use, during installation, first, the mounting base 2 is placed in a suitable position, the mounting base 2 is fixed through the fixing bolts 4 inside the mounting plate 3, then the lightning arrester body 1 is placed into the mounting box 5, the rotating knob 9 is rotated to drive the bidirectional screw rod 8 to rotate, since the bidirectional screw rod 8 is threadedly connected with the connecting block 7 and the connecting block 7 is slidingly connected with the mounting box 5, the rotation of the bidirectional screw rod 8 causes the relative movement of the clamping plates 6 on the two sides, the natural rubber antiskid pads 15 on the sides of the clamping plates 6 contact and clamp the lightning arrester body 1, during the clamping process, the antiskid pads 15 increase the friction force to ensure that the lightning arrester body 1 is stable and will not be damaged, at the same time, when the rotating knob 9 is rotated, the limiting rods 12 slide out of the limiting holes 10 under the action of the tension springs 14, when the lightning arrester body 1 is clamped, the limiting rods 12 are inserted into the limiting holes 10 under the action of the tension springs 14, preventing the rotating knob 9 from being accidentally rotated to cause the rotation of the bidirectional screw rod 8 and the loosening of the clamping plates 6, if the position of the mounting plate 3 needs to be adjusted during installation, the sliding block 17 can be slid in the sliding groove 16 on the side of the mounting base 2 to achieve the adjustment, after the position is adjusted, the positioning rods 18 on the side of the mounting plate 3 are screwed into the corresponding positioning holes 19 on the side of the mounting base 2 to ensure that the position of the mounting plate 3 is fixed, thereby completing the installation of the lightning arrester, during disassembly, first, the positioning rods 18 are unscrewed from the positioning holes 19, the position of the mounting plate 3 is adjusted or kept unchanged according to the requirement, then the limiting rods 12 are pulled out of the limiting holes 10, the rotating knob 9 is reversely rotated, the bidirectional screw rod 8 is reversely rotated to cause the opposite movement of the clamping plates 6 on the two sides, the lightning arrester body 1 is loosened, finally, the fixing bolts 4 are unscrewed, the mounting base 2 and the lightning arrester body 1 can be taken off, the disassembly is completed. Through the cooperation of various components, the convenient installation and disassembly of the lightning arrester and the position adjustment during installation are realized, so as to adapt to different installation environments and requirements.

[0029] The above is only a preferred embodiment of the present application, and does not limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still falls within the protection scope of the technical scheme of the present application.
