[0029] The fixing structure includes a snap-fitting portion 3 which is arranged on the first side edge 22 and protrudes toward the second side edge 12. The shapes of the light-transmitting area 11 and the light-shielding cover 2 are long strips that fit each other. The light-shielding cover 2 is provided with a long portion 4 and a wide portion according to the length and width. The snap-fitting portion 3 is arranged on the long portion 4. The number of the long portions 4 is two. The snap-fitting portion 3 is arranged on two long portions 4. The longest distance between the snap-fitting portions 3 is greater than the width of the light-transmitting area 11. The snap-fitting portion 3 is arranged on the long portion 4 of the light-shielding cover 2, so that the entire light-shielding cover 2 is subjected to more uniform force and is not easy to fall off.

The portion where the buckling portion 3 is connected to the shading surface 21 is provided with a slope 31. The slope 31 is inclined from top to bottom. The slope 31 can guide the shading cover 2 so that the shading cover 2 can be more conveniently assembled in the light-transmitting area 11.
[0031] The buckle part 3 is in a triangular shape, so that after the light shielding cover 2 is assembled, the buckle part 3 will not affect the appearance of the product too much.
[0032] There are two long portions 4 and four buckling portions 3, so that the entire light shielding cover 2 is subjected to a more uniform force and is not easy to fall off. The first side edge 22 is deformed by the inward pressure of the buckling portions 3, making the light shielding cover 2 not easy to fall off and more secure.
[0033] The light shielding cover 2 is provided with a fixed edge 5 , the height of the first side edge 22 is greater than the height of the second side edge 12 , and the fixed edge 5 is deformed after being subjected to force and separated from the light transmission area 11 to realize the disassembly of the light shielding cover 2 .
[0034] Embodiment 2
[0035] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the utility model discloses a shading cover fixing structure of a floor indication pattern, comprising a surface cover 1, provided with a hollow light-transmitting area 11, a shading cover 2, made of an opaque plastic material, provided with a shading surface 21 and a first side 22, the first side 22 being formed around the shading surface 21, a second side 12 being provided inside the light-transmitting area 11, the first side 22 being in contact with the second side 12, a fixing structure being provided between the first side 22 and the second side 12, the structure is simple, and the fixing structure can make the assembly more secure.
[0036] The fixing structure includes a snap-fitting portion 3 which is arranged on the second side edge 12 and protrudes toward the first side edge 22. The shapes of the light-transmitting area 11 and the light-shielding surface 21 are long strips that match each other. The light-transmitting area 11 is provided with a long portion 4 and a wide portion according to the length and width, and the snap-fitting portion 3 is arranged on the long portion 4, so that the light-shielding cover 2 is subjected to force more evenly and is not easy to fall off.
[0037] The buckling portion 3 is in a triangular shape. Since the light shielding cover 2 is made of plastic, after the light shielding cover 2 is assembled, the position where the first side edge 22 contacts the buckling portion 3 will be forced to be concave inward, so that the user cannot observe the buckling portion 3 outside the face cover 1, and the overall appearance of the product will not be affected.
[0038] There are two long portions 4 and four buckling portions 3, which are arranged on two long portions 4. The entire light shielding cover 2 is subjected to force more evenly and is not easy to fall off. The first side edge 22 is deformed by the inward pressure of the buckling portions 3, making the light shielding cover 2 not easy to fall off and more secure.
[0039] The light shielding cover 2 is provided with a fixed edge 5 , the height of the first side edge 22 is greater than the height of the second side edge 12 , and the fixed edge 5 is deformed after being subjected to force and separated from the light transmission area 11 to realize the disassembly of the light shielding cover 2 .
[0040] In order to illustrate the use principle of the present application, the light-transmitting area 11 is further explained. The light-transmitting area 11 is a digital sign in the shape of an "8". The digital sign in the shape of an "8" is composed of three horizontal diamond-shaped bars and four vertical diamond-shaped bars spliced in the shape of an "8". The digital sign in the shape of an "8" on the far left can be adjusted to shade the tens digit and negative numbers of the corresponding floors, and the digital sign in the shape of an "8" on the right can be adjusted to shade the units digit of the corresponding floors. The "F" representative floor does not need to be shaded. The light-shielding cover 2 is separated from the surface cover 1 by disassembling the light-shielding cover 2, thereby achieving the purpose of being able to adjust the pattern according to the scene, facilitating production, having strong applicability and wide application. Figure 8 As shown, when this embodiment is used, the light shielding cover 3 is removed and the indicator light displays "23F".
