They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Please see Figure 1-7 This utility model provides a technical solution: a serpentine curtain structure combining pulleys and trolleys, comprising:

[0040] The curtain box structure includes an end 1 and a track 2, which are mounted on the wall by mounting brackets 9. The track 2 is inserted and positioned in the mounting opening 11 of the end 1, and a mounting cavity 21 is provided throughout the track. The bottom of the mounting cavity 21 extends to the surface of the track 2 through a gap 22.

[0041] Several fixed-distance pulleys 3 and at least one main trolley 4 are slidably disposed in the mounting cavity 21 at their tops, and a first retaining sleeve 30 and a second retaining sleeve 43 extend downward from their bottoms respectively.

[0042] The curtain 5 has several clips 51 at its top;

[0043] The clamping lug 6 is positioned at the bottom of the curtain box structure, and a third clip 64 is provided on its side. The third clip 64, the first clip 30, and the second clip 43 are correspondingly engaged with the clip block 51.

[0044] A drive mechanism that drives the main trolley 4 to slide within the mounting cavity 21;

[0045] The pull rope 10 connects to the fixed-distance pulley 3, the main pulley 4, and the clamping lug 6.

[0046] The top of the mounting cavity 21 has a protruding rib 12 extending inward, and the top outer surface of the track 2 is provided with an arc-shaped notch 23. The protruding rib 12 is fitted onto the arc-shaped notch 23 to improve the structural assembly stability.

[0047] The fixed-distance pulley 3 includes a base 31, and a notch 34 is provided at the bottom of the base 31. The connecting block 35 at the top of the first sleeve 30 slides into and is rotatably engaged in the notch 34, so that when the curtain 5 slides, the first sleeve 30 is pulled, which will drive the connecting block 35 to rotate along the notch 34, thereby relieving force, reducing the squeezing between the fixed-distance pulley 3 and the track 2, and ensuring stable sliding and positioning.

[0048] The top of the fixed-distance pulley 3 and the main trolley 4 are respectively provided with a first guide wheel 32 and a second guide wheel 42. The first guide wheel 32 and the second guide wheel 42 abut against the bottom surface of the mounting cavity 21 to reduce the sliding resistance of the fixed-distance pulley 3 and the main trolley 4 in the track.

[0049] The fixed-distance pulley 3 is provided with an arc-shaped plate 33 below the first guide wheel 32. The convex surface of the arc-shaped plate 33 faces upward and abuts against the outer surface of the track 2. When the fixed-distance pulley 3 or the curtain 5 is subjected to tension, the fixed-distance pulley 3 will swing relative to the swing track 2. The first guide wheel 32 and the arc-shaped plate 33 cooperate to support the surface of the track 2 and ensure the stability of the structure.

[0050] The clamping lug 6 includes an inverted L-shaped base plate 61. The side of the L-shaped base plate 61 is positioned on the side of the wall by bolts or pins, and its top is positioned at the bottom of the end 1 by fasteners 62. An insert block 63 is also provided on its top. The insert block 63 is inserted into the slot at the bottom of the end 1 to further improve the overall assembly stability of the curtain box structure and the end of the curtain fabric 5.

[0051] The drive mechanism includes a conveyor belt 7 and a motor 8. The conveyor belt 7 is arranged inside the mounting port 11 and the mounting cavity 21, and outside the gap 22. The protrusion on its inner side is positioned with the positioning groove 41 on the side of the main trolley 4. The inner surface of its end is connected to a transmission gear. The transmission gear is arranged inside the mounting port 11. The output shaft 81 of the motor 8 is connected to one of the transmission gears.

[0052] The mounting bracket 9 is positioned on the wall by bolts or pins, and is provided with a limiting groove 91 and a pre-tightening tongue 92. The limiting groove 91 is engaged with the preset positioning plate on the wall, and the pre-tightening tongue 92 is elastically abutted against the curtain box structure. By setting the limiting groove 91 and the pre-tightening tongue 92, the positioning strength between the mounting bracket 9 and the wall and curtain box structure can be further improved, and the structure can be prevented from loosening.

[0053] The working principle of the serpentine curtain structure combining pulleys and trolleys in this embodiment includes: when the motor 8 is running, the output shaft 81 drives the transmission gear to rotate and synchronously drives the conveyor belt 7 to rotate. The main trolley 4 is pulled and begins to slide in the mounting cavity 21. When the curtain is closed, the pull cord 10 is pulled, which will synchronously pull the fixed-distance pulleys 3, so that they gradually move away from each other. During this time, the pull cord 10 is taut, thereby achieving the closure of the curtain 5. When the curtain is opened, the main trolley 4 will push the fixed-distance pulleys 3 one by one, so that they slide toward the clamping lugs 6, thereby achieving the opening of the curtain 5.

[0054] In summary, due to the adoption of the above technical solution, the serpentine curtain structure combining pulleys and trolleys in this embodiment has the following advantages compared to the prior art:

[0055] This utility model's serpentine curtain structure utilizes a serpentine arrangement and interlocking of fixed-distance pulleys, a main trolley, and the curtain fabric. The main trolley, driven by a drive mechanism, ensures a serpentine distribution when the curtain is open, maintaining aesthetic appeal. The fixed-distance pulleys, main trolley, and clamping lugs are connected by pull ropes, allowing for dual upward and downward pulling of the curtain fabric when closed. This ensures smooth movement of the fixed-distance pulleys and main trolley within the installation cavity, resulting in stable curtain opening and closing. The compact structure of each component reduces the required installation space for the curtain. The rotatable design between the fixed-distance pulleys, the installation cavity, and the curtain fabric reduces compression and wear between components, extending their service life.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
