[0015] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0016] A protective cover for an insulator, such as Figure 1As shown, it includes a plurality of movable latches 1 and two cover bodies 2 arranged opposite to each other, and a concave cavity 3 is arranged on one side of the cover bodies 2 opposite to each other, wherein; both ends of the cover body 2 are respectively provided with an avoidance arc groove 9, and the avoidance arc groove 9 is connected with the concave cavity 3; the two sides of the cover body 2 are respectively provided with a first extension side strip 4 and a second extension side strip 5, and a plurality of first buckle rings 6 are arranged in a row in the middle of the upper end surface of the first extension side strip 4, and a plurality of insertion holes 7 are respectively arranged on both sides of the upper end surface of the first extension side strip 4, and second buckle rings 8 are respectively arranged on both sides of the upper end surface of the second extension side strip 5, and the second buckle ring 8 is arranged corresponding to the insertion hole 7. When the two cover bodies 2 arranged opposite to each other are spliced ​​with each other, the second buckle ring 8 is inserted into the insertion hole 7, the first extension side strip 4 is tightly fitted with the second extension side strip 5, and the movable latch 1 is plugged into the first buckle ring 6 and the second buckle ring 8. Specifically, when two cover bodies 2 that are arranged opposite to each other are spliced ​​together, an accommodating space for accommodating the insulator is formed between the concave cavities 3 of the two bodies, and the avoidance arc grooves 9 of the two cover bodies 2 are spliced ​​together to form an axial hole for the two ends of the insulator to extend out. The utility model has a novel structure and a clever design, and the insulator is accommodated between the two cover bodies 2. When the two cover bodies 2 that are arranged opposite to each other are spliced ​​together, the two bodies can be locked and the first extended side strip 4 and the second extended side strip 5 can be tightly fitted by inserting the movable pin 1 into the first buckle ring 6 and the second buckle ring 8, so as to avoid the gap between the two bodies from entering sand, dust, paint and other materials into the concave cavity 3 to pollute the insulator, thereby protecting the insulator, having a reliable structure, and preventing the insulator from being damaged. Moreover, under the above-mentioned arrangement, the cover body 2 is convenient to assemble and disassemble, easy to replace and repair, and has strong flexibility in use.
