[0030] Referring to Figs. 1, 2 and 3 for the embodiment of the light box cover panel of the present invention, the left and right side edges of the light box cover panel 1 respectively have a dust-proof groove, and the groove is filled with a sealing strip 10. The front plate surface is a convex arc surface, the rear plate surface is a plane, the upper edge of the plate body has an upper load-bearing hook 11, the lower edge of the plate body has a lower load-bearing hook 12, and the head 14 of the load-bearing hook The neck 13 of force hook head expands. The back of the upper and lower load-bearing hooks is flush with the plate body, and the neck 13 front of the load-bearing hooks is concave. The neck 13 from the board body to the force-bearing hook gradually becomes thinner from the front of the board body to the rear direction of the board body. The lower jaw of the load-bearing hook head protrudes forward, the top of the head is flat, and an inclined slope is formed from t...
