[0045] Second embodiment

[0046] Please refer to Figures 5-7 Based on the weather-proof lightning arrester insulation protective cover provided in the first embodiment of the application, another weather-proof lightning arrester insulation protective cover is provided in the second embodiment of the application. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the separate implementation of the first embodiment.

[0047] Specifically, the weather-proof lightning arrester insulation protective cover provided in the second embodiment of the application is different in that two mounting boxes 9 are fixedly connected to the top of the protective cover body 1, a sliding block 10 is slidably connected in the mounting box 9, a compression spring 11 is arranged between the top of the sliding block 10 and the top of the inner wall of the mounting box 9, a pull rod 12 is fixedly connected to the top of the sliding block 10, and a limiting rod 13 is fixedly connected to the bottom of the sliding block 10.

[0048] The top end of the pull rod 12 penetrates the mounting box 9 and extends to the top of the mounting box 9, and the bottom end of the limiting rod 13 penetrates the protective cover body 1 and extends to the bottom of the protective cover body 1.

[0049] The side wall of each of the two side plates 4 is fixedly connected with a fixed block 14, a limiting hole 15 is formed in the fixed block 14, and the limiting hole 15 is matched with the limiting rod 13.

[0050] The bottom end of the limiting rod 13 is an arc surface, which facilitates the resetting of the side plate 4. The arc surface structure is easy to bear stress. When the side plate 4 is reset, the fixed block 14 swings in an arc shape, so that the limiting rod 13 is lifted upward through the arc surface at the bottom end of the limiting rod 13, and then the sliding block 10 presses and compresses the compression spring 11. After the arc swing of the fixed block 14, the limiting hole 15 is aligned with the limiting rod 13. At this time, the compression spring 11 rebounds, the limiting rod 13 is inserted into the limiting hole 15, and the side plate 4 is fixed.
