[0030] This folding curtain track structure incorporates a 180-degree folding transmission box 1 and two telescopic guide rail assemblies 2, with one end of each guide rail assembly 2 connected to both ends of the transmission box 1. This allows the track to be folded 180 degrees and then retracted, transforming it into a very short configuration. This significantly improves packaging, storage, and transportation convenience, thereby reducing costs associated with these processes.

[0031] like Figures 1 to 4 As shown, the telescopic guide rail assembly 2 includes a large guide rail 21 and a small guide rail 22. One end of the large guide rail 21 and one end of the small guide rail 22 are slidably nested together. The other end of the large guide rail 21 or the other end of the small guide rail 22 is connected to one end of the transmission box 1. This telescopic guide rail assembly 2 is very simple and reliable, which not only facilitates manufacturing but also gives it high reliability, thereby helping to further improve the reliability and applicability of the folding curtain track structure.

[0032] like Figure 4 , Figure 6 and Figure 7As shown, both the large guide rail 21 and the small guide rail 22 are laterally extending guide rails. The bottom surface of the large guide rail 21 has a laterally extending guide groove 211. The front and rear walls of the guide groove 211 each have laterally extending guide grooves 212. The upper walls of the two guide grooves 211 each have laterally extending guide grooves 213, which are upwardly extending and then curved towards each other as limiting grooves. Laterally extending support protrusions 214 are respectively provided on the lower sidewall edges of the two guide grooves 212 near the guide groove 211. The bottom surface of the small guide rail 22 has a laterally extending T-shaped... The T-shaped groove 221 has transversely extending T-shaped limiting grooves 222 on its inner front and rear walls. The top surface of the small guide rail 22 has two guide protrusions 223 that respectively match the two guide grooves 213. The front and rear ends of the small guide rail 22 are respectively embedded in the front and rear guide grooves 212. The opening of the T-shaped groove 221 is fitted onto the two supporting protrusions 214, with the inner lower groove wall of the T-shaped groove 221 lower than or flush with the top surface of the supporting protrusions 214. The two guide protrusions 223 are slidably inserted into the two guide grooves 213. This large guide rail 21 and small guide rail 22 have a very simple and reliable structure, which not only facilitates manufacturing but also ensures that the sliding nesting of the large guide rail 21 and small guide rail 22 is very stable and reliable, thereby helping to further improve the reliability and applicability of this folding curtain track structure.

[0033] like Figures 1 to 5 , Figures 8 to 10 As shown, the folding curtain track structure also includes a trolley assembly 3, which includes a sliding block 31, a hanging block 32, and a clamping body 33 for clamping the transmission belt. The sliding block 31 has sliding grooves 311 on its front and rear surfaces, the hanging block 32 is disposed on the lower end of the sliding block 31, and one end of the clamping body 33 is vertically slidably disposed on the upper end of the sliding block 31. The upper end of the sliding block 31 is horizontally slidably embedded in the T-shaped groove 221, and the two sliding grooves 311 are respectively slidably clamped in the opening of the T-shaped groove 221, the opening of the guide groove 211, and the guide protrusion 223. The other end of the clamping body 33 is placed in the T-shaped limiting groove 222. By using such a trolley assembly 3, and with the cooperation of the relevant grooves on the large guide rail 21 and the small guide rail 22, it is possible to accurately and stably limit and guide the trolley assembly 3. In addition, the T-shaped limiting groove 222 restricts the movement, and the clamping body 33 can be vertically slidably set on the sliding block 31. This makes the traction of the trolley assembly 3 by the transmission belt very accurate and stable, thereby ensuring that the opening and closing of the curtains is very accurate and stable, and further helping to improve the reliability and applicability of the folding curtain track structure.

[0034] like Figures 8 to 12As shown, the clamping body 33 includes an upper clamping block 331, a lower clamping block 332, and a plugging block 333.

This clamping body 33 is very simple and reliable, which not only facilitates manufacturing but also assembly, and ensures that the assembly of the clamping body 33 and the sliding block 31 is very accurate and stable, thereby helping to further improve the accuracy and stability of the curtain movement.

[0035] like Figures 8 to 12 As shown, the lower locking block 332 has several insertion posts 3321 and several hooks 3322 respectively provided on its front and rear top surfaces. Each insertion post 3321 is inserted into the upper locking block 331, and each hook 3322 is hooked onto the upper locking block 331. The wall of the locking hole 334 is provided with a toothed groove 3341. This makes the assembly of the upper locking block 331 and the lower locking block 332 very stable and reliable, thereby helping to further improve the stability of the locking body 33 in locking the transmission belt. The toothed groove 3341 can be engaged with the toothed transmission belt, thereby helping to further improve the reliability of the locking body 33 in locking the transmission belt. In turn, it helps to further improve the reliability and applicability of the folding curtain track structure.

[0036] like Figures 8 to 10 As shown, a secondary trolley assembly 10 can be hinged to the sliding block 31. The secondary trolley assembly 10 can adopt the assembly structure of the sliding block 31 and the clamping body 33 described above. This can help enhance the positioning effect on the curtain, thereby helping to further improve the reliability and applicability of the folding curtain track structure.

This transmission housing 1 is very simple and reliable, which not only facilitates manufacturing but also ensures very stable transmission of the transmission belts, thereby helping to further improve the reliability and applicability of the folding curtain track structure.

[0038] like Figures 1 to 3As shown, the other ends of the two telescopic guide rail assemblies 2 are respectively fitted with transmission heads 4 that transmit the power output from the curtain motor to the transmission belt. This allows users to choose to install the curtain motor on the left or right side depending on different installation conditions, which helps to further improve the reliability and applicability of the folding curtain track structure.

[0039] like Figures 1 to 3 As shown, each of the two telescopic guide rail assemblies 2 is equipped with a transmission belt (not shown in the figure) to drive the trolley assembly 3. One end of each of the two transmission belts is respectively fitted onto the two transmission ends of the gear transmission assembly 13, and the other end of each of the two transmission belts is respectively fitted onto the corresponding transmission end 4. One of the transmission end 4 is equipped with a curtain motor (not shown in the figure).
