[0039] The adjustable multi-curtain has multiple shielding units 2, the shielding units 2 are independent of each other, can be moved and positioned independently, and have different shielding areas due to different overlapping areas. For example, the shielding units 2 can be all lifted to the upper end or the lower end of the area to be shielded, that is, all the shielding units 2 are completely overlapped, so that the maximum light transmission effect is achieved, and the lower part or the upper part of the area to be shielded can be selected to transmit light, as shown in Figs. 2 and 8; or the shielding units 2 can be lifted to be partially located at the upper end of the area to be shielded and partially located at the lower end of the area to be shielded, so that the light transmission effect of the middle area is achieved, and the light transmission area of the middle area can also be adjusted due to the movable adjustment of the different overlapping areas of the shielding units 2.

[0040] As a further improved embodiment, the shielding unit 2 has an upper edge and a lower edge, and in order to prevent light leakage during shielding, when the area to be shielded is completely shielded, the lower edge of each shielding unit 2 overlaps the upper edge of the shielding unit 2 directly below it, and the overlapping area is generally limited to the edge portion, and should not be too much to prevent reducing the light transmission area and increasing the processing cost.

[0041] As a further improved embodiment, the lifting assembly adopts a pull rope 31, a winding rope rod or a pulley, and the winding rope rod or the pulley is arranged in the accommodating cavity of the upper beam 1. One end of the pull rope 31 is fixed to the winding rope rod or the pulley, and the other end is fixed to the shielding unit 2. The end of the shielding unit 2 not fixed to the pull rope 31 is generally a free end, that is, in a free hanging state. The height position of the shielding unit 2 is changed by winding and unwinding the pull rope 31. Specifically, the winding rope rod can be driven to rotate by the power transmitted by the driving mechanism, so that the pull rope 31 can be wound and unwound by the winding rope rod, or the pulley is driven by the driving mechanism to slide along the sliding rail arranged in the accommodating cavity, so that the pull rope 31 is pulled to be wound and unwound.

The pull rope 31 is arranged in the vertical lifting guide rail, which is more beautiful.

[0043] As a further improved embodiment, the shielding unit 2 includes three groups of first shielding unit 21, second shielding unit 22 and third shielding unit 23. For ease of description, the shielding unit closest to the outer edge of the upper beam 1 is listed as the first shielding unit 21, followed by the second shielding unit 22 and the third shielding unit 23. The three groups of shielding units are movable, or the first shielding unit 21 is not movable while the second and third shielding units are movable. It should be noted that the shielding unit 2 can be one group, two groups, three groups, four groups, etc. The number of groups is determined according to the area of the area to be shielded, the proportion of the area of the shielding unit 2, and the customization needs of consumers. The setting methods of the shielding unit are not exhaustively listed. For reference, Fig. 1 shows three groups of shielding units, including the first shielding unit 21, the second shielding unit 22 and the third shielding unit 23.
