Therefore, the left and right sides of the frame 1 are inclined surfaces of the frame 1 which are inclined upwards and converged, and the motion trail can be matched.
Referring to fig. 5 to 7, preferably, the closed side of the ceiling block 2 is provided with a convex portion 14 protruding toward the closing direction and a concave portion 15 recessed toward the opening direction, the convex portion 14 and the concave portion 15 are matched with each other and respectively occupy half of the closed side of the ceiling block 2, and the convex portions 14 and the concave portions 15 of the two ceiling blocks 2 are arranged in a central symmetry manner, so that the convex portion 14 of any one ceiling block 2 and the concave portion 15 of another ceiling block 2 are engaged with each other when the two ceiling blocks are completely closed. Furthermore, the convex part 14 and the concave part 15 of the same ceiling block 2 are transited by a first bevel edge 17; an inner shielding plate 16 protruding towards the closing direction is fixedly arranged above the concave part 15, and a second inclined edge 18 which is mirror-symmetrical to the first inclined edge 17 is arranged on one side, close to the first inclined edge 17, of the inner shielding plate 16; when the two ceiling tiles 2 are completely closed, the inner shielding plate 16 is closed above the convex portion 14 of the other ceiling tile 2; when two ceiling blocks 2 leave a gap, two first bevel edges 17 and two second bevel edges 18 enclose a central hole 19 in the center of the closing line of the ceiling blocks 2.
Due to the unique design of the ceiling block 2, when the ceiling block 2 is not completely closed, a central hole 19 is reserved in the center of the ceiling block 2, the equipment above the ceiling block 2 runs downwards and is exposed below the ceiling block 2 after the ceiling block 2 is opened, and a space can be reserved for a hoisting part of the equipment when the ceiling block 2 is closed. The ceiling tile 2 is now not completely closed, but the shading action is substantially completed.
