[0041] like Figure 1 As shown, a modular manual curtain track includes several track units 100 and fixing units for connecting and fixing adjacent track units 100. Each track unit 100 can have the same or different lengths, thus allowing for the assembly of curtain tracks of any length using the fixing units. Figure 12 and Figure 13 As shown.

[0042] As in 1- Figure 8 As shown, the track unit 100 includes a left rail 1 and a right rail 2 arranged opposite to each other. The left rail 1 and right rail 2 are respectively provided with elastic hooks 3 and locking grooves 4 for the elastic hooks 3 to engage with. That is, the elastic hooks 3 can be located on either the left rail 1 or the right rail 2, and the locking grooves 4 are correspondingly located on the other. In this embodiment, the elastic hooks 3 are located on the left rail 1, and the locking grooves 4 are located on the right rail 2. Multiple elastic hooks 3 are arranged along the length of the left rail 1, and multiple locking grooves 4 are also arranged along the length of the right rail 2. Each elastic hook 3 corresponds one-to-one with a locking groove 4, and each elastic hook 3 engages with its corresponding locking groove 4. The elastic hook 3 is integrally formed with the left rail 1, with one end fixed to the left rail 1 and the other end suspended and protruding to form a hook portion that connects with the locking groove 4. Figure 11 As shown.

[0043] The fixing unit includes docking connecting pieces 5 located at both ends of the track unit 100 along its length direction and docking connecting grooves 6 for the docking connecting pieces 5 to be inserted. The docking connecting pieces 5 are provided with elastic buckles 7, and the docking connecting grooves 6 are recessed to form locking grooves 8 for the elastic buckles 7 to be engaged.

[0044] The connecting piece 5 is integrally formed with the side rail (the left side rail 1 and the right side rail 2 are collectively referred to as the side rail) and has a chamfer at the end facing away from the side rail. A through groove is provided in the middle of the connecting piece 5. The elastic lock 7 is set in the through groove, and one end of it is fixed to the groove wall of the through groove. The other end is suspended and protrudes to form a protrusion that hooks with the locking groove 8. Both the protrusion and the locking groove 8 have guide slopes.

[0045] During assembly, firstly, the elastic hook 3 of the left track 1 is inserted into the locking groove 4 of the right track 2 to lock the left track 1 and the right track 2 to form track unit 100. Then, two adjacent track units 100 are fixed by connecting them together. When connecting, the connecting piece 5 of one track unit 100 is inserted into the connecting groove 6 of the other track unit 100. During the insertion process, the elastic buckle 7 on the connecting piece 5 is simultaneously engaged into the locking groove 8 in the connecting groove 6 to fix the two track units 100. In this way, multiple track units 100 of equal or unequal length can be assembled to form a curtain track of a predetermined length.

[0046] In some examples, the left rail 1 has a left locking plate 9 protruding toward the right rail 2 and a left locking groove 10 with an opening facing the right rail 2. Multiple left locking plates 9 and left locking grooves 10 are provided along the length direction of the left rail 1. Elastic hooks 3, left locking plates 9 and left locking grooves 10 are alternately arranged. The left rail 1 protrudes to form several transverse ribs extending along its length direction and longitudinal ribs extending along its height direction. The transverse ribs and longitudinal ribs are arranged intersectingly. The left plate protrudes toward the right plate to form a ridge. The ridge and the uppermost transverse rib form the aforementioned left locking groove 10.

[0047] The right rail 2 has a right locking plate 11 that protrudes toward the left rail 1 to engage with the left locking slot 10 and a right locking slot 12 that opens toward the left rail 1 for the left locking plate 9 to engage. Multiple right locking plates 11 and right locking slots 12 are provided along the length of the right rail 2. The locking slots 4, right locking plates 11 and right locking slots 12 are alternately arranged. The right rail 2 protrudes to form several transverse ribs extending along its length and longitudinal ribs extending along its height. The transverse ribs and longitudinal ribs are arranged intersectingly. The right rail 2 protrudes toward the left rail 1 to form a convex strip. The convex strip and the uppermost transverse rib form the aforementioned right locking slot 12.

[0048] In some examples, the ends of the left rail 1 and the right rail 2 are respectively provided with positioning bosses 13 and positioning grooves 14 for the positioning bosses 13 to engage. In this embodiment, the positioning bosses 13 are located on the left locking plate 9 of the left rail 1, and the positioning grooves 14 are located on the right rail 2. During the assembly of the left rail 1 and the right rail 2, the positioning bosses 13 and the positioning grooves 14 are first aligned and inserted to achieve that the end faces of the left rail 1 and the right rail 2 are flush. During the insertion of the positioning bosses 13 and the positioning grooves 14, the elastic hooks 3 engage with the locking grooves 4 to lock the left rail 1 and the right rail 2.

[0049] In some examples, the track unit 100 has docking positioning protrusions 15 and docking positioning holes 16 for the docking positioning protrusions 15 to be inserted at both ends along its length. There are multiple docking positioning protrusions 15 and docking positioning holes 16. Each docking positioning protrusion 15 corresponds to a different docking positioning hole 16, and each docking positioning protrusion 15 is inserted into its corresponding docking positioning hole 16. During the assembly of two adjacent track units 100, the docking positioning protrusions 15 and docking positioning holes 16 are first aligned and inserted to achieve horizontal and vertical alignment of the two track units 100. During the insertion of the docking positioning protrusions 15 and docking positioning holes 16, the elastic latch 7 engages with the locking groove 8 to fix the two track units 100.

[0050] In some examples, the track unit 100 is provided with a docking separation hole 17 at the location corresponding to the locking groove 8, which communicates with the locking groove 8 to push out the elastic latch 7 in the locking groove 8. When the curtain track needs to be disassembled, a tool is used to insert into the locking groove 8 through the docking separation hole 17 to push out the elastic latch 7 in the locking groove 8. At this time, the two adjacent track units 100 are unlocked, and the docking connecting piece 5 can be separated from the docking connecting groove 6.

[0051] In some examples, such as Figures 14-18 As shown, both the left rail 1 and the right rail 2 are injection molded, and both have different cross-sectional shapes along their respective lengths. During the injection molding process, the steps of mold closing, injection, pressure holding, cooling, and mold opening can be highly automated, and the time of each step can be precisely controlled. Compared with some other molding processes, such as extrusion molding, it can complete the production of a single product in a shorter time. Injection molding can achieve mass production, high product dimensional accuracy, excellent product mechanical properties, and a smooth, flat, and low-roughness surface, which can meet the appearance quality requirements of most products.

[0052] In some examples, such as Figure 1 and Figure 3As shown, the left rail 1 and the right rail 2 are recessed on their adjacent sides to form an inner fixing groove 18. The two inner fixing grooves 18 are opposite each other to form an inner fixing cavity for the installation fixing code 23 to be inserted. The installation fixing code 23 is inserted into the inner fixing cavity to form an inner locking structure. The curtain track can be installed in any position by installing the fixing code 23.

[0053] In some examples, such as Figure 5 and Figure 7 As shown, the left rail 1 and the right rail 2 are recessed on opposite sides to form an outer fixing groove 19. The two outer fixing grooves 19 are opposite to each other to form an outer fixing cavity for the installation fixing code 23 to be inserted. The installation fixing code 23 is inserted into the outer fixing cavity to form an outer clamping structure. The curtain track can be installed in any position by installing the fixing code 23.

[0054] In some examples, such as Figure 12 As shown, the curtain track has adjustable end caps 20 installed at both ends along its length. The end caps 20 can be finely adjusted along the length of the curtain track to achieve precise adjustment of the curtain track length. Specifically, the end caps 20 are slidably fitted onto the ends of the curtain track and their ends are sealed. Adjusting screws are installed on the end caps 20. By abutting the adjusting screws at different positions on the curtain track, the end caps 20 can be fixed at different positions on the curtain track to achieve length adjustment of the curtain track.

[0055] In some examples, such as Figure 11 As shown, the left rail 1 and the right rail 2 protrude toward each other to form a left slide rail 21 and a right slide rail 22, respectively. The left slide rail 21 and the right slide rail 22 enclose each other to form a slide for the hanging ring 24 to slide. The end cap 20 blocks both ends of the slide along its length to prevent the hanging ring 24 from slipping off.

[0056] Working principle:

[0057] During assembly, first align and insert the positioning boss 13 of the left rail 1 with the positioning groove 14 of the right rail 2, making the end faces of the left rail 1 and the right rail 2 flush. Simultaneously, the left locking plate 9 of the left rail 1 engages with the right locking groove 12 of the right rail 2, and the right locking plate 11 of the right rail 2 engages with the left locking groove 10 of the left rail 1. Furthermore, the elastic hook 3 of the left rail 1 engages with the locking groove 4 of the right rail 2 to lock the left rail 1 and the right rail 2 together, forming the track unit 100. Figure 9 and Figure 10 As shown;

[0058] Then, two adjacent track units 100 are connected and fixed by a fixing unit. When connecting and fixing, the docking positioning protrusion 15 is first aligned and inserted with the docking positioning hole 16 to make the two track units 100 aligned and positioned horizontally and vertically. At the same time, the docking connecting piece 5 of one track unit 100 is inserted into the docking connecting groove 6 of the other track unit 100. During the insertion process, the elastic buckle 7 on the docking connecting piece 5 is simultaneously engaged into the locking groove 8 to fix the two track units 100. In this way, multiple track units 100 of equal or unequal length are assembled to form a curtain track of a predetermined length.
