[0024] Beneficial effects:

[0025] This utility model's curtain trolley assembly uses positioning components to position the inner end of the curtain fabric within the trolley assembly. When the curtain closes, the positioning components on opposite sides of the trolley assembly press together, causing the ends of the curtain fabric on both sides to be pressed together. This prevents light leakage caused by gaps between the curtain fabrics. Furthermore, the magnetic pre-tightening effect of the positioning components further enhances the degree of closure. The single-sided slider, clamping plate, insert, clip, and iron arm adopt a modular design, with tight assembly and splicing, facilitating production and assembly. This improves the structural strength of the trolley assembly, allowing it to slide stably under the drive of the curtain's internal drive device, achieving smooth opening and closing of the curtain.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0033] Please see Figure 1-2 This utility model provides a technical solution: a tightly closed serpentine curtain trolley assembly, comprising:

[0034] At least two single-sided sliders 1, whose opposite sides are joined together;

[0035] At least two clamping plates 2 are integrally disposed at the bottom of the single-sided slider 1, and a clamping opening 21 is formed between adjacent clamping plates 2;

[0036] Insert 3, which is inserted into the clamp 21;

[0037] Clip 4, which is attached to the outside of the clip plate 2;

[0038] Iron arm 5 is sleeved on the outside of insert 3 and clamp 4. The first mounting hole 22 on clamp 2, the second mounting hole 31 on insert 3, the fourth mounting hole 41 on clamp 4 and the sixth mounting hole 51 on iron arm 5 are positioned by bolts or pins. The insert 3, clamp 4 and iron arm 5 are also provided with a third mounting hole 32, a fifth mounting hole 42 and a notch 52 respectively. The third mounting hole 32, the fifth mounting hole 42 and the notch 52 are positioned by bolts or pins.

[0039] Positioning component 6 is assembled on the side of the iron arm 5 and is positioned with the inner end of the curtain.

[0040] The single-sided slider 1, clamping plate 2, insert 3, clamping plate 4 and iron arm 5 adopt a modular design, which facilitates production and assembly, thereby improving the structural strength of the trolley assembly and enabling it to slide stably under the drive of the drive device inside the opening and closing curtain, thus realizing the smooth opening and closing of the opening and closing curtain.

[0041] A first slot 11 is vertically provided through the joint of adjacent single-sided sliders 1. A first tooth 33 extends from the top of the insert 3 and is inserted into the first slot 11. The first tooth 33 is engaged with the side of the clamping plate 2. A second slot 12 is also vertically provided through the single-sided slider 1. A second tooth 34 extends from the top of the insert 3 and is inserted into the second slot 12. The second tooth 34 is engaged with the side of the clamping plate 2. The embedded insertion design of the insert 3 and the single-sided slider 1 can further improve the connection strength between the single-sided slider 1 and the iron arm 5, thereby ensuring the stability of the sliding drive of the single-sided slider 1 and the synchronous pulling of the curtain.

[0042] The single-sided slider 1 is equipped with a pulley 7, which, together with the design of multiple single-sided sliders 1, ensures that the trolley assembly is fully connected with the track, preventing it from shifting up and down or sideways during driving, thus affecting the stable operation of the opening and closing curtain. At the same time, it reduces the sliding resistance of the trolley assembly in the opening and closing curtain track.

[0043] The second assembly hole 31 is a horizontally extending waist-shaped hole, which facilitates the connection and assembly of bolts, pins and multiple assembly holes.

[0044] The third assembly hole 32, the fifth assembly hole 42, and the notch 52 are vertically extending waist-shaped structures to further position the insert 3, the clamp 4, and the iron arm 5.

[0045] The positioning element 6 engages with the locking block on the curtain fabric, and the positioning elements 6 on the opposite surfaces of adjacent trolley assemblies are magnetically connected. One of the two positioning elements 6 is equipped with a magnet, and the other is equipped with a magnetic material or another magnet with opposite magnetic poles, so as to achieve a magnetic pre-tightening effect between the structures and further ensure the tightness of the curtain fabric when closed.

[0046] The working principle of a tightly closed serpentine curtain trolley assembly in this embodiment includes: during assembly, the side sliders 1 of a single trolley assembly are joined together, the insert 3 is inserted into the clamp 21, and the two-tooth structure is inserted into the corresponding slot; the clamp 4 is attached to the clamp plate 2, and the iron arm 5 is sleeved on the outside of the above structure and locked to the structure by bolts or pins; the above trolley assembly is assembled inside the curtain and connected to the drive device, and the inner end of the curtain fabric is positioned on the positioning part 6, specifically by snap-fit ​​or other positioning methods. Figure 2 As shown, when the curtain is closed, the positioning parts 6 on opposite sides of the inner end pulley assembly of the two curtains press together, so that the ends of the two curtains are pressed together, thereby improving the degree of curtain closure and avoiding light leakage caused by gaps between the curtains.

[0047] In summary, due to the adoption of the above technical solution, the tightly closed serpentine curtain trolley assembly of this embodiment has the following advantages compared with the prior art:

[0048] This utility model's curtain trolley assembly uses positioning components to position the inner end of the curtain fabric within the trolley assembly. When the curtain closes, the positioning components on opposite sides of the trolley assembly press together, causing the ends of the curtain fabric on both sides to be pressed together. This prevents light leakage caused by gaps between the curtain fabrics. Furthermore, the magnetic pre-tightening effect of the positioning components further enhances the degree of closure. The single-sided slider, clamping plate, insert, clip, and iron arm adopt a modular design, with tight assembly and splicing, facilitating production and assembly. This improves the structural strength of the trolley assembly, allowing it to slide stably under the drive of the curtain's internal drive device, achieving smooth opening and closing of the curtain.

[0049] 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.
