[0029] like Figures 1 to 4 As shown, the curtain telescopic guide rail device of this utility model includes a plurality of short guide rail bodies 1, which are arranged side by side in a horizontal manner and adjacent short guide rail bodies 1 can be folded and connected together. After each short guide rail body 1 is unfolded, the guide rail parts of each short guide rail body 1 can be assembled into a guide rail 10, and at least one of the short guide rail bodies 1 is a telescopic guide rail body.

[0030] This curtain telescopic guide rail device employs several short guide rail bodies 1, arranged horizontally side-by-side. Adjacent short guide rail bodies 1 can be folded and connected together. When unfolded, the guide rail sections of all short guide rail bodies 1 can be combined to form a single guide rail 10. Furthermore, at least one of the short guide rail bodies 1 is a telescopic guide rail. This allows for easy folding and retraction of the curtain telescopic guide rail device during packaging, eliminating the need for long packaging bags or boxes, large storage spaces, and ample transfer space in packaging and storage workshops. It also eliminates the need for large trucks for transportation, improving the convenience of production packaging, storage management, and transportation for manufacturing enterprises, reducing costs and alleviating significant burdens. Simultaneously, users can easily take the curtain telescopic guide rail device home and install it, effectively improving the convenience of retrieval and installation.

[0031] like Figure 2 and Figure 4 As shown, the curtain telescopic guide rail device also includes a folding assembly 2. Adjacent short guide rail bodies 1 can be folded together via the folding assembly 2, and both ends of the folding assembly 2 are nested and connected to the opposite ends of the adjacent short guide rail bodies 1. The use of the folding assembly 2 and the nested connection facilitates the folding and connection of adjacent short guide rail bodies 1, thereby further improving the applicability of the curtain telescopic guide rail device.

[0032] like Figure 2 , Figure 4 , Figures 8 to 11As shown, the folding assembly 2 includes a connecting block 21 and two insert blocks 22. The two insert blocks 22 are respectively inserted into the ends of two adjacent short guide rails 1. The two insert blocks 22 are horizontally rotatably hinged to the left and right ends of the connecting block 21. Each of the two insert blocks 22 is provided with a transverse guide portion 221, which is aligned with the guide rail direction of the short guide rail 1. The guide rail portions on adjacent short guide rails 1 can be joined together through the corresponding transverse guide portions 221 to form a continuous guide structure. This allows adjacent short guide rails 1 to be folded and connected through the connecting block 21. Such a folding connection not only has a very simple structure but also facilitates a stable and reliable folding connection effect, thereby helping to further improve the reliability and applicability of the curtain telescopic guide rail device.

[0033] like Figures 8 to 11 As shown, the lateral guide portion 221 is located below the outer end of the corresponding insertion block 22; the opposite end faces of the two lateral guide portions 221 are arc-shaped. This allows the opposite ends of the two lateral guide portions 221 to be closer together while still allowing for folding, thus facilitating more stable and smooth guidance, and further improving the reliability and applicability of the curtain telescopic guide rail device.

[0034] like Figures 9 to 11 As shown, vertically arranged convex shaft portions 211 are provided on the bottom surface of the left and right ends of the connecting block 21. The opposite ends of the two plug-in blocks 22 are rotatably fitted onto the corresponding convex shaft portions 211, allowing the plug-in blocks 22 to rotate horizontally around the axis of the convex shaft portion 211. A positioning block 23 is arranged at the bottom of the connecting block 21, with the left and right ends of the positioning block 23 respectively connected to the two convex shaft portions 211, and the left and right ends of the positioning block 23 respectively placed on the bottom surface of the two plug-in blocks 22 connected to the corresponding convex shaft portions 211. This not only allows for convenient and stable assembly of the plug-in blocks 22 and the connecting block 21, but also effectively meets the folding requirements of the folding assembly 2, thereby better meeting the needs of actual use and further improving the reliability and applicability of the curtain telescopic guide rail device.

[0035] like Figure 4 , Figure 10 and Figure 11As shown, a reinforcing protrusion 212 is provided on the middle of the bottom surface of the connecting block 21. The end face of the insert block 22 facing the reinforcing protrusion 212 is arc-shaped. A downwardly protruding protrusion 213 is provided on the front and rear sides of the middle of the bottom surface of the connecting block 21. A limiting protrusion 214 is provided on the left and right sides of the lower end of the protrusion 213. A limiting gap 215 for the traction track to pass through is formed between the protrusion 213 and the reinforcing protrusion 212, and between the two limiting protrusions 214 and the connecting block 21. A limiting groove 222 is provided on the lower sides of the front and rear of the outer end of the insert block 22. The connecting block 21 can rotate 90 degrees horizontally forward and backward. After the connecting block 21 rotates 90 degrees forward or backward, the corresponding limiting groove 222 can be fitted onto the corresponding limiting protrusion 214. This not only enables the folding assembly 2 to be folded quickly and accurately, but also, after folding, the corresponding limiting protrusion 214 and limiting groove 222 cooperate to restrict the up-and-down swing of both ends of the hinge. Before folding the folding assembly 2, the middle part of the limiting gap 215 can restrict the traction track, so that the traction track can exert a more stable traction effect. After folding the folding assembly 2, the traction track can enter both ends of the limiting gap 215, which can stably restrict the traction track after folding, thus ensuring a very high stability after folding. This can avoid damage and deformation of the hinge during folding, packaging, and transportation, thereby further improving the reliability and applicability of the curtain telescopic guide rail device.

[0036] like Figure 9 and Figure 11 As shown, a transverse through-hole mortise 2121 is provided on the bottom surface of the reinforcing protrusion 212. The middle part of the positioning block 23 is embedded in the mortise 2121, and both ends of the positioning block 23 are fixed to the corresponding convex shaft 211 by screws. The insertion block 22 is fixed to the end of the short guide rail 1 by screws. This facilitates a more stable and reliable limiting effect on the positioning block 23, thereby further improving the reliability of the folding assembly 2.

[0037] like Figures 2 to 4As shown in Figure 10, the guide rail portion of the short guide rail body 1 is a hanging rail groove 12 formed on its bottom surface, and the hanging rail groove 12 extends along the length direction of the short guide rail body 1. The transverse guide portion 221 forms a guide groove corresponding to the hanging rail groove 12. The plug block 22 has a clearance gap 223 that connects the hanging rail groove 12 and the guide groove and makes the hanging rail groove 12 and the guide groove transition smoothly. The hanging rail groove 12, the clearance gap 223 and the guide groove together constitute the guide rail 10. The guide rail 10 is used for the installation of the trolley assembly 20 and the sliding hanging ring 30. The guide rail 10 is equipped with a traction track 40. The left and right ends of the short guide rail body 1 of the curtain telescopic guide rail device are respectively provided with transmission boxes 50, and the two ends of the traction track 40 are respectively wound around the two transmission boxes 50. This makes the guidance very stable and smooth, which helps to further improve the reliability and applicability of the curtain telescopic guide rail device, and thus can well meet the needs of actual use.

[0038] like Figures 2 to 4 As shown, a positioning sleeve 11 is slidably fitted onto the short guide rail body 1, allowing the positioning sleeve 11 to slide and engage with the folded connection ends of two adjacent short guide rail bodies 1. Thus, after the folding assembly 2 is unfolded, the positioning sleeve 11 serves to restrict and reinforce the folded connection point of the two short guide rail bodies 1, further improving the stability and reliability of the curtain telescopic guide rail device, thereby enhancing its applicability. Using a sliding mounting of the positioning sleeve 11 not only enables rapid folding but also prevents the positioning sleeve 11 from being lost or omitted.

[0039] like Figure 2 As shown, the guide rail portion of the short guide rail body 1 is horizontally positioned on the center of its bottom surface. The positioning sleeve 11 is sleeve-shaped, and a clearance notch 111 is provided on the center of its bottom surface to avoid the guide rail portion. This positioning sleeve 11 not only has a very simple structure but also provides a more stable and reliable restraint at the fold, thereby further improving the reliability and applicability of the curtain telescopic guide rail device.

[0040] like Figures 3 to 6 As shown, the short guide rail body 1 includes a wide guide rail strip 13 and a narrow guide rail strip 14, with one end of the narrow guide rail strip 14 slidably embedded within the wide guide rail strip 13. This short guide rail body 1 is very simple, which not only facilitates manufacturing but also effectively meets the needs of telescopic movement, thereby helping to further improve the applicability of the curtain telescopic guide rail device.

[0041] like Figure 5 and Figure 6As shown, a support member 131 is provided inside the wide guide rail 13. The support member 131 has a laterally extending storage slot 1311. A first guide wheel 15 is provided on the support member 131. A second guide wheel 16 is provided on the narrow guide rail 14. The second guide wheel 16 is located inside the storage slot 1311 and can move laterally inside the storage slot 1311 as the narrow guide rail 14 is pushed into the wide guide rail 13. The first guide wheel 15 and the second guide wheel 16 can be wound around the traction track 40. Specifically, after one half of the traction track 40 is wound around the first guide wheel 15, the second guide wheel 16 is wound around it, and finally it is wound around the transmission box 50. In this way, when the short guide rail body 1 is shortened, part of the traction track 40 can be stably folded into the storage tray 1311; and when the short guide rail body 1 is unfolded, the traction track 40 can also be stably unfolded. Such a curtain telescopic guide rail device can have higher stability and applicability.

[0042] like Figure 6 and Figure 7 As shown, the support member 131 is horizontal, and the receiving slot 1311 is a horizontal groove formed on the top surface of the support member 131. A gap is reserved between the lower part of the receiving slot 1311 and the lower wall of the hanging rail groove 12 for the trolley assembly 20 and the sliding ring 30 to pass through. The end of the support member 131 away from the narrow guide rail 14 is embedded in the plug block 22. The groove wall of the support member 131 near the narrow guide rail 14 is provided with an installation groove 1312 and a clearance groove 1313, with the installation groove 1312 extending through to the side wall of the support member 131 and the clearance groove 1313 extending through to the end face of the support member 131 near the narrow guide rail 14. The first guide wheel 15 is installed in the installation groove 1312. The first guide wheel 15 is a gear. The traction track 40 is a toothed belt. The side wall of the support member 131 is provided with a clearance notch 1314, and the two ends of the clearance notch 1314 pass through the mounting groove 1312 and the end face of the support member 131 away from the narrow guide rail 14, respectively. The end of the narrow guide rail 14 near the wide guide rail 13 is fitted with a positioning member 141, and the second guide wheel 16 is set on the positioning member 141. The traction track 40 passes through the clearance notch 1314 and is placed in the mounting groove 1312. Then, the traction track 40 is wrapped around the first guide wheel 15. Then, the traction track 40 is placed in the receiving groove 1311. Then, the traction track 40 is wrapped around the second guide wheel 16. Then, the traction track 40 passes out from the clearance groove 1313 and is wrapped around the transmission box 50. This not only enables a more stable retraction and storage of the traction track 40, but also makes the unfolding more stable and accurate, thereby helping to further improve the reliability and applicability of the curtain telescopic guide rail device.

[0043] like Figures 1 to 4As shown, four short guide rails 1 are arranged horizontally side by side. The two left and right rails are telescopic, while the two middle rails are not telescopic, allowing adjacent short guide rails 1 to fold and connect together. This shortens the curtain telescopic guide rail device to about 1 / 6 of its unfolded state, eliminating the need for long packaging boxes and large storage spaces. This improves the convenience of packaging, storage management, and transportation, reduces the cost and burden on enterprises, and enhances the convenience for users to retrieve and install the curtains.
