The outer surface of the base plate 5 is provided with a locking component 6 for locking the rotating disk 305.

[0029] Specifically, the limiting assembly 3 includes a connecting block 601 fixedly connected to the outer surface of the base plate 5, the outer surface of the connecting block 601 is fixedly connected to a connecting cylinder 602, the inner wall of the connecting cylinder 602 is fixedly connected to a compression spring 603, one end of the compression spring 603 is fixedly connected to a limiting pin 604, the outer surface of the limiting pin 604 is fixedly connected to a protruding block 605, a limiting groove is provided on the outer surface of the rotating disk 305, and a rectangular groove for sliding of the protruding block 605 is provided on the outer surface of the rotating disk 305, the length of the rectangular groove is greater than the depth of the limiting groove, the rotating block 307 passes through one end of the limiting frame 304 and is fixedly connected to the limiting disk 306, the distance between the two fixed blocks 303 is greater than the radius of the rotation path of the rotating block 307, the outer surface of the rotating disk 305 is hinged with a handle, and the inner sides of the two folding plates 1 are provided with two magnets 2 for connecting the folding plates 1 to the charging pile.

[0030] Furthermore, the raised block 605 is pulled, thereby driving the limit pin 604 to squeeze the compression spring 603, thereby driving the limit pin 604 to disengage from the groove on the outer surface of the rotating disk 305, and then the rotating disk 305 is driven to rotate by the handle, and the rotating disk 305 drives the rotating block 307 to move, thereby driving the limit frame 304 to rise and fall.

Example

[0031] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , which is the second embodiment of the present utility model, is based on the previous embodiment. The filter assembly 4 includes a fixed frame 401 fixedly connected to the outer surface of the folding plate 1, and the filter plate 402 is movably connected inside the fixed frame 401. Both sides of the fixed frame 401 are hinged with a rotating rod 403, and both sides of the filter plate 402 are provided with teeth 406 that cooperate with the rotating rod 403. The outer surface of the fixed frame 401 is fixedly connected to two extrusion springs 405, and the bottom end of the extrusion spring 405 is fixedly connected to the outer surface of the rotating rod 403.

[0032] Specifically, a square groove is provided on the outer surface of the fixed frame 401, and the rotating rod 403 is hinged to the inner wall of the square groove.

A fixing plate 404 is provided on the top of the filter plate 402. The fixing plate 404 can close the opening at the top of the fixing frame 401, and when the filter plate 402 is inserted into the fixing frame 401, the spring piece 407 on the lower surface of the fixing plate 404 can apply pressure to the inner wall of the fixing frame 401, thereby preventing the filter plate 402 from loosening in the fixing frame 401.

[0034] Working principle: When using the charging protective shell to protect the charging pile, fit the base plate 5 to the back of the charging pile, then rotate the two folding plates 1 so that the inner side of the folding plate 1 fits the side of the charging pile, thereby fixing the folding plate 1, and then pull the protruding block 605 to drive the limit pin 604 to squeeze the compression spring 603, thereby driving the limit pin 604 to disengage from the groove on the outer surface of the rotating disk 305, and then drive the rotating disk 305 to rotate through the handle, and the rotating disk 305 drives the rotating block 307 to move, thereby driving the limit frame 304 to rise. When the rotating block 307 moves, the limiting plate 306 prevents the rotating block 307 from being separated from the limiting frame 304. When the limiting frame 304 descends, the fixed block 303 drives the lifting rod 302 to descend, thereby driving the top plate 301 to descend and squeeze the charging pile, and finally achieving rapid limit to complete the installation of the protective shell. The outer surface of the folding plate 1 is provided with a filter assembly 4. By inserting the filter plate 402 into the fixed frame 401, during the insertion of the filter plate 402, the teeth 406 on both sides of the filter plate 402 drive the rotating rod 40 3 is rotated downward, so that the filter plate 402 is smoothly inserted into the fixed frame 401. After the filter plate 402 is inserted into the fixed frame 401, the rotating rod 403 is reset under the action of the extrusion spring 405, so that the filter plate 402 is restricted inside the fixed frame 401 by the rotation rod 403 on the teeth 406. A fixing plate 404 is provided on the top of the filter plate 402. The fixing plate 404 can close the opening on the top of the fixed frame 401 and can be fixed during the process of inserting the filter plate 402 into the fixed frame 401. The spring piece 407 on the lower surface of the plate 404 applies pressure to the inner wall of the fixed frame 401, thereby preventing the filter plate 402 from loosening in the fixed frame 401. A vent for ventilation is provided inside the folding plate 1. When replacing the filter plate 402, the rotating rod 403 is rotated so that the rotating rod 403 releases the limit on the teeth 406, so that the filter plate 402 can be pulled out from the fixed frame 401, thereby realizing the replacement of the filter plate 402, and finally realizing the rapid limited installation of the charging protection shell, and being able to filter the air at the vent position of the charging pile.
