[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 As shown, the utility model provides a lightning arrester shielding cover, including a cover body 1, a flexible wire tube 5 is arranged on the upper part of one side of the cover body 1, the flexible wire tube 5 is a flexible plastic tube, and other flexible tubes such as rubber tubes can also be used. The flexible wire tube 5 itself is flexible and can conveniently lead out the lead of the lightning arrester from different directions; a wire seam 4 is arranged on the side of the cover body 1, and the wire seam 4 extends from the bottom edge of the cover body 1 to the bottom of the flexible wire tube 5, and a tube bottom groove 10 is formed at the bottom of the flexible wire tube 5 corresponding to the wire seam 4, and the upper end of the wire seam 4 is connected to the tube bottom groove 10, and the tube bottom groove 10 is equal in length to the flexible wire tube 5;

[0026] The cover body 1 is provided with an adapter 6, and the adapter 6 protrudes out of the surface of the cover body 1; a positioning hole 8 is provided in the middle of the adapter 6, and a plurality of external positioning grooves 9 are provided on the circumferential surface of the adapter 6, and the external positioning groove 9 is an arc groove, and a straight groove or other forms of grooves can also be used, which can be conveniently matched with the insulating rod for positioning. The positioning hole 8 and the arc groove are provided, and the insulating rod can be conveniently matched with the adapter 6. During operation, a hook or a block can be provided at the end of the insulating rod. By inserting the hook into the positioning hole 8 and hooking it with the adapter 6, or matching the block position with the external positioning groove 9, the direction of the cover body 1 can be adjusted, so that when the installer is away from the lightning protection cover, the installation and position adjustment of the shielding cover are convenient; two adapters 6 are provided, and they are centrally symmetrically distributed on the surface of the cover body 1. The provision of two adapters 6 can further improve the convenience of positioning and installation of the cover body 1; a plurality of reinforcing ribs are provided at the junction of the adapter 6 and the cover body 1. Since the adapter 6 needs to move with the insulating rod, in order to improve the stability of its matching with the cover body 1, reinforcing ribs need to be provided;
