[0029] Reference Figure 1 and Figure 2The utility model provides an overlapping roller blind combination structure, including a roller blind box body 1 and a guide unit 2. When the overlapping roller blind combination structure is actually used, the number of roller blind boxes 1 is at least two, and all roller blind boxes 1 are arranged adjacent to each other in sequence. The guide unit 2 is connected to the roller blind box body 1 and is located below the curtain outlet. In this embodiment, it is preferred that a guide unit 2 is provided at every two adjacent roller blind boxes 1, and the setting direction and setting angle of the guide unit 2 at the junction of two adjacent roller blind boxes 1 can match the setting direction and setting angle of the roller blind box body 1. In this way, the guide unit 2 can form a guiding positioning for two adjacent curtains 3, and the guide unit 2 is preferably kept horizontal with the outlet of the curtain 3, so that the guide unit 2 can apply pressure to the curtain, so that the shape and angle of the two adjacent curtains at the overlapping part cooperate with the guide unit 2, and the overlapping part between the two adjacent curtains can remain tight and flat during the rising and falling process, thereby ensuring the overall operation effect.
[0030] As an optional implementation, the guide unit 2 includes a guide tube 21 , and the setting direction and setting angle of the guide tube 21 at the junction of two adjacent rolling shutter boxes 1 can match the setting direction and setting angle of the rolling shutter boxes 1 .
[0031] As an optional implementation, the guide tube 21 is detachably connected to the roller shutter box 1. This arrangement makes the guide tube 21 easy to disassemble and assemble. When necessary, the guide tube 21 may not be used. In this case, the guide tube 21 can be directly removed for flexible selection and use.
[0032] As an optional implementation, the guide tube 21 is connected to the roller shutter box body 1 with bolts. As a specific connection mode of detachable connection, the bolt connection has good connection strength and is easier to disassemble and assemble.
[0033] As an optional implementation, adjacent rolling shutter boxes 1 are staggered in the height direction. Such an arrangement can provide more installation space between adjacent rolling shutter boxes 1, making the overall structure more compact and having better space utilization.
[0034] As an optional implementation, adjacent rolling shutter boxes 1 are offset in the front-to-back direction. Such an arrangement can provide more installation space between adjacent rolling shutter boxes 1, making the overall structure more compact and having better space utilization.
[0035] In actual use, adjacent roller shutter boxes 1 can be flexibly arranged to be offset in the height direction or in the front-to-back direction according to actual use requirements.
[0036] As an optional embodiment, it also includes an overlapping unit 4, which is arranged on the side edge of the curtain 3. The side edges of two adjacent curtains 3 are overlapped by the overlapping unit 4.
