[0027] Embodiment:

[0028] The embodiment of the present application discloses a high-hardness flame-retardant PC lampshade with a self-locking structure, please refer to Figures 1-5The utility model relates to a lampshade body 1, the upper end of lampshade body 1 is fixedly connected with top ring 2, the inner wall of top ring 2 is equipped with annular groove 21, the inner wall of top ring 2 is fixedly connected with first arc block 4 and second arc block 5, the inner wall of top ring 2 is rotatably connected with arc block 3, the gap between first arc block 4 and second arc block 5 is cavity 6, the outer surface of arc block 3 is fixedly connected with arc slider 31, the one side upper end of arc block 3 is fixedly connected with through block 32, the upper end of through block 32 is fixedly connected with handle 321, the upper end of second arc block 5 is equipped with through slot 51, the outer side wall of through slot 51 is equipped with first placing slot 52 and second placing slot 53, and the inside of first placing slot 52 and second placing slot 53 is slidably provided with locking piece 54.

[0029] Arc slider 31 is slidably connected with annular groove 21, through block 32 penetrates through the inside of through slot 51, through block 32 is slidably connected with through slot 51, and handle 321 is attached to the upper end of second arc block 5.

[0030] Arc slider 31 is used for preventing arc block 3 from separating from top ring 2, handle 321 is used for driving through block 32 to slide along through slot 51, that is, the position of arc block 3 in the inside of top ring 2 is changed by through block 32.

[0031] The upper side wall of second placing slot 53 is equipped with first limiting slot 531, and the lower side wall of second placing slot 53 is equipped with second limiting slot 532.

[0032] First limiting slot 531 is used for limiting the upper end of locking piece 54, and second limiting slot 532 is used for limiting the lower end of locking piece 54, that is, locking piece 54 is prevented from separating from the inside of second placing slot 53.

[0033] The both ends of locking piece 54 are fixedly connected with rotating rod 541, the outer side of locking piece 54 is fixedly connected with first spring 542 and second spring 543, the rotating rod 541 of the upper end of locking piece 54 is rotatably connected with first limiting slot 531, and the rotating rod 541 of the lower end of locking piece 54 is rotatably connected with second limiting slot 532.

[0034] The existence of rotating rod 541 facilitates the rotation of locking piece 54 in the inside of second placing slot 53.

[0035] One end of first spring 542 is fixedly connected with the inner wall of one side of second placing slot 53, and one end of second spring 543 is fixedly connected with the inner wall of the other side of second placing slot 53.
