In addition, the turnover ropes 20 are arranged on two sides of the curtain sheet 10, in order to conveniently control the curtain sheet 10 to turn over, a swinging rope 30 is arranged between the turnover ropes 20 on two sides, the swinging rope 30 can drive the curtain sheet 10 to swing obliquely, when the curtain sheet 10 turns over, the swinging rope 30 connected between the turnover ropes 20 can be embedded into the avoidance groove 21, under the avoidance action of the avoidance groove 21, the swinging rope 30 can not directly block the edge of the curtain sheet 10, namely the edge of the coaming 2, so that the coaming 2 and the shielding ladder 3 can be completely abutted together so as to resist light rays injected from the side parts, and the avoidance groove 21 can be conveniently clamped into the swinging rope 30, so that the matching requirement is lower, and the curtain sheet 10 can be turned over conveniently. Due to the fact that the avoidance groove 21 is formed, light rays can still be emitted from the avoidance groove 21, at the moment, the outer sides of the adjacent support plates 1 and the shielding steps 3 can form a convex structure, under shielding of the convex structure, the light rays obliquely emitted from the avoidance groove 21 can be blocked by the convex structure, and therefore the support plates 1 and the shielding steps 3 form a second-layer shielding structure for shielding the light rays.
In addition, the supporting plate 1 is provided with a through hole 11, the lifting rope 40 of the blind is arranged on the through hole 11 in a penetrating way, the lifting rope 40 is used for controlling the lifting of the curtain sheet 10, when the curtain sheet 10 is overturned, the through hole 11 can swing relative to the lifting rope 40, and the friction between the lifting rope 40 and the curtain sheet 10 is reduced, so that the curtain sheet 10 can swing conveniently.
The embodiment of the invention has the following beneficial effects:
according to the embodiment of the invention, the curtain sheet 10 with high shielding performance is provided with the supporting plate 1, the coaming 2 and the shielding ladder 3 and the light shielding plate 4 connected between the supporting plate 1 and the coaming 2, wherein the supporting plate 1, the shielding ladder 3, the light shielding plate 4 and the coaming 2 enclose a concave structure, when shielding is needed, the curtain sheet 10 is turned over, the coaming 2 can be abutted to the shielding ladder 3 of the adjacent curtain sheet 10, at the moment, the coaming 2 and the shielding ladder 3 of the adjacent curtain sheet 10 form a side light shielding structure, the structure is different from the traditional straight-piece curtain sheet, after the curtain sheet 10 is turned over, a convex structure is generated, light entering from an inclined direction is blocked, the width of the concave structure can avoid the overlong condition of the width of the curtain sheet 10, the coaming 2 is provided with the avoiding groove 21, the turning rope 20 of the coaming can be penetrated into the avoiding groove 21, under the effect of the avoiding groove 21, when the coaming sheet 10 is turned over, the edge of the coaming 2 is abutted to the swinging rope 20, and the edge of the coaming 2 can be prevented from being completely inserted into the swinging rope 20, and the edge 30 can be prevented from being completely embedded into the swinging rope 20. The enclosing plate 2 and the light shielding plate 4 are of a first layer structure for shielding light rays, so that the light rays entering from the horizontal direction or the inclined direction can be blocked, the supporting plate 1 and the shielding ladder 3 form a second layer structure for shielding the light rays, and the light rays passing through the avoiding groove 21 can be shielded, so that the inclined light rays can be effectively prevented from penetrating out, and the shielding structure has higher concealment.
Specifically, one side of shielding ladder 3 incline to connect in the edge of backup pad 1, the opposite side with light screen 4 incline to connect, shielding ladder 3 with backup pad 1 forms the first shielding platform 5 of evagination, follow dodge the light that groove 21 passed can be blocked by first shielding platform 5, first shielding platform 5 is the structure of blocking light of second floor, shielding ladder 3 with light screen 4 forms the second shielding platform 6 of evagination. The oblique light is blocked by the second blocking table 6 before entering the avoiding groove 21, and the second blocking table 6 forms a third layer structure for blocking the light. Therefore, in the invention, besides the first layer light blocking structure formed by the coaming plate 2 and the light shielding plate 4 and the second layer light blocking structure formed by the supporting plate 1 and the shielding step 3, the third layer light blocking structure formed by the coaming plate 2 and the shielding step 3 is also arranged, so that complete and thorough light blocking is realized, and the shielding performance is extremely high.
In order to facilitate the overturning of the curtain sheet 10, the through holes 11 are oblong holes, the length direction of the through holes 11 is perpendicular to the length direction of the supporting plate 1, the through holes 11 can provide a larger movable space for the lifting rope 40, and friction between the lifting rope 40 and the curtain sheet 10 can be reduced, so that the curtain sheet 10 can be overturned conveniently. When the curtain sheet 10 is turned over, when the lifting rope 40 contacts with the edge of the perforation 11, the curtain sheet 10 is at a light-transmitting limit position or a shielding limit position, so that the length of the perforation 11 can limit the limit angle of opening and closing of the curtain sheet 10, and when the curtain sheet 10 is turned over to the limit angle, the coaming 2 can be abutted against the shielding step 3 adjacent to the curtain sheet 10 by reasonably setting the length of the perforation 11.
In the present invention, the through hole 11 is offset from the axis of the support plate 1 in the longitudinal direction and is provided on the side close to the shielding step 3, specifically, the ratio of the distance L1 from the end of the through hole 11 away from the shielding step 3 to the center line to the distance L2 from the end of the through hole 11 close to the shielding step 3 to the center line is (3-5) with the axis at the width of the support plate 11/2 as the center line: 10, by setting the distances L1 and L2, the center of gravity of the support plate 1 and the curtain sheet 10 can be shifted, so that the curtain sheet 10 can be turned over and shielded more easily. When the curtain sheet 10 needs to be opened, the turnover rope 20 drives the curtain sheet 10 to turn over, the relative positions of the perforation 11 and the lifting rope 40 can be moved, namely, the position of the turnover center of the curtain sheet 10 can be changed, the lifting rope 40 is positioned on the side far away from the shielding step 3 before the curtain sheet 10 turns over, the turnover center is far away from the gravity center position, the lifting rope 40 gradually moves towards the direction of the shielding step 3 along with the turnover of the curtain sheet 10, and the turnover center gradually deviates towards the side of the shielding step 3, namely gradually approaches the gravity center position, so that the distance between the curtain sheet 10 and the gravity center can be reduced as much as possible, and the curtain sheet 10 is easier to open.
It should be noted that, the conventional curtain sheet 10 is designed symmetrically, that is, two portions of the curtain sheet 10 bent with each other are symmetrical, the symmetrical design has an obvious characteristic that, before and after the curtain sheet 10 is turned over, the upper and lower edges of the curtain sheet 10 are all abutted against the turning ropes 20 on two sides of the curtain sheet 10, the upper and lower edges of the curtain sheet 10 always generate friction resistance with the turning ropes 20, and the distance between the two turning ropes 20 is approximately equal to the distance between the two swinging ropes 30 (or the distance between the two curtain sheets 10), so that the distance between the two curtain sheets 10 can be constrained by the distance between the two turning ropes 20, thereby restricting the density of the curtain sheet 10 and further affecting the light-shielding property.
The shape of the curtain sheet 10 with high shielding performance is different from that of the traditional curtain sheet 10, namely the curtain sheet 10 in the embodiment of the invention is of an asymmetric design, namely the curtain sheet 10 formed by the supporting plate 1, the shielding ladder 3, the light shielding plate 4 and the coaming 2 is of an asymmetric structure, the shielding ladder 3, the light shielding plate 4 and the coaming 2 are heavier than the supporting plate 1, the gravity center of the curtain sheet is lower, and the curtain sheet 10 is matched with the perforation 11 of the oblong hole, when the curtain sheet 10 is turned downwards, the gravity center of the curtain sheet 10 is downwards moved, and the whole curtain sheet 10 is driven to downwards move along the swinging rope 30 which is obliquely downwards, so that the edge of the supporting plate 1 is far away from the turning rope 20.
