[0030] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a structural schematic diagram of the multifunctional adjustable curtain provided in this application. Figure 2 yes Figure 1 The diagram shows another state of the adjustable curtain. Specifically, the adjustable curtain 100 (hereinafter referred to as "curtain 100") includes: a positioning component 10, a pull cord 20 and a curtain fabric 30, a first track component 400 and a second track component 70.

[0031] like Figure 1 As shown, the adjustable curtain 100 is installed inside the window frame 200 to block light from entering the space inside the window frame 200.

[0032] The positioning component 10 is configured to be connected to one end of the window frame 200. The function of the positioning component 10 is to fix one end of the pull cord 20, so that the curtain 30 can move along the pull cord 20.

[0033] exist Figure 1 and Figure 2 In the embodiment shown, the positioning component 10 is connected to the upper end of the window frame 200.

[0034] It is understood that in some embodiments, the positioning component 10 may also be located at the lower end of the window frame 200. In other embodiments, the positioning component 10 may also be located on the left or right side of the window frame 200, etc.

[0035] like Figure 3 and Figure 4 As shown, Figure 3 yes Figure 1 The diagram shown is a partial exploded view of the adjustable curtain. Figure 4 yes Figure 1 The exploded view of the adjustable curtain shown indicates that, in some embodiments, the positioning component 10 includes a fixing part 11, a snap-fit ​​part 12, and a bending part 13 connected in sequence. The fixing part 11, the snap-fit ​​part 12, and the bending part 13 form a snap-fit ​​cavity 101, with the fixing part 11 and the bending part 13 arranged parallel to each other.

[0036] The fixing part 11 has a first fixing hole 111 and a second fixing hole 112. The first fixing hole 111 is used to engage with a screw 113 to fix the positioning component 10, and the second fixing hole 112 is used to fix one end of the pull rope 20. The positioning component 10 has a simple structure, low cost, and is easy to assemble.

[0037] In other embodiments, the positioning component 10 may also be other fixing structures, such as a buckle structure, which can hook one end of the pull rope 20 and can be fastened to the first track component 400.

[0038] A pull cord 20 is threaded through a curtain 30, which can be expanded and contracted along the pull cord 20 to close and open the curtain 100. Figure 1 In the illustrated embodiment, two pull cords 20 are provided, each supporting the curtain 30 from both ends. In other embodiments, two or more pull cords 20 may be provided to support the curtain 30.

[0039] The first track assembly 400 includes a first track 60, a flexible mounting bracket 40, and an unlocking assembly 50. For example... Figure 7 and Figure 4 As shown, the flexible mounting bracket 40 is located on the first track 60 and at one end of the curtain 30 near the positioning component 10.

[0040] The flexible mounting bracket 40 has a locked state and an unlocked state. In the locked state, the flexible mounting bracket 40 locks the pull cord 20, preventing the flexible mounting bracket 40 and the curtain 30 from moving along the pull cord 20. In the unlocked state, the flexible mounting bracket 40 unlocks the pull cord 20, allowing the flexible mounting bracket 40 to move the curtain 30 along the pull cord 20.

[0041] like Figure 7 As shown, the unlocking component 50 is connected to the resilient mounting bracket 40, and the unlocking component 50 is configured to switch the resilient mounting bracket 40 between an unlocked state and a locked state.

[0042] In the above embodiments, when it is necessary to control the unfolding and retraction of the curtain 30, that is, when it is necessary to move the curtain 30, the elastic mounting bracket 40 can be unlocked by the unlocking component 50, thereby allowing the curtain 30 and the elastic mounting bracket 40 to move. When it is not necessary to move the curtain 30, the elastic mounting bracket 40 can be locked by the unlocking component 50, thus locking the pull cord 20 and keeping the elastic mounting bracket 40 and the curtain 30 stationary. The curtain 100 of the above embodiments has a simple structure, is lightweight, and has low manufacturing and transportation costs.

[0043] Furthermore, the first track 60 may be disposed on the upper side of the curtain 30, and the second track assembly 70 may be disposed on the lower side of the curtain 30. In other embodiments, the first track 60 may be disposed on the lower side of the curtain 30, and the second track assembly 70 may be disposed on the upper side of the curtain 30.

[0044] like Figure 4 As shown, the first track 60 has an installation cavity (not shown in the figure), the elastic mounting bracket 40 and the unlocking component 50 are disposed in the installation cavity 601, and the first track 60 has an opening (not shown in the figure) communicating with the installation cavity, through which the pull rope 20 passes. End caps 611 are respectively provided at both ends of the first track 60.

[0045] When the curtain 30 is moved, and the elastic mounting bracket 40 is in the unlocked state, the first track 60 can also move along the pull rope 20.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, the flexible mounting bracket 40 includes: a mounting bracket base 41, a flexible buckle 42, and a spring 43.

[0047] The mounting bracket base 41 is located in the mounting cavity of the first track 60, and the mounting bracket base 41 forms a receiving cavity (not shown in the figure).

[0048] The mounting bracket base 41 includes a first side plate 411, a second side plate 412, a third side plate 413, and a base plate 414, wherein, as shown... Figure 3 and Figure 5 As shown, the first through hole 402 is opened on the base plate 414, and the pull rope 20 can pass through the first through hole 402.

[0049] The elastic buckle 42 is disposed within the receiving cavity, and one end of the elastic buckle 42 is connected to the unlocking component 50. The elastic buckle 42 is provided with a through hole 403, through which the pull rope 20 passes through the elastic buckle 42.

[0050] One end of the spring 43 abuts against the elastic buckle 42, and the other end of the spring 43 abuts against the mounting bracket base 41. In the unlocked state, the unlocking component 50 pulls the elastic buckle 42, and the elastic buckle 42 squeezes the spring 43 to retract the elastic buckle 42. In the locked state, the spring 43 pushes the elastic buckle 42 to reset.

[0051] Specifically, such as Figure 3 As shown, the elastic buckle 42 may include a retractable portion 421 and a connecting portion 422. The retractable portion 421 is connected to one end of the connecting portion 422, the spring 43 is sleeved on the connecting portion 422, the unlocking component 50 is connected to the other end of the connecting portion 422, and the retractable portion 421 is provided with a second through hole 403.

[0052] A hook-on portion 423 may be provided on the side of the retractable portion 421 away from the connecting portion 422. The hook-on portion 423 is configured to cooperate with the positioning component 10. The hook-on portion 423 can be hooked into the snap-fit ​​cavity 101 to fix the elastic mounting bracket 40.

[0053] In the unlocked state, such as Figure 6 As shown, the first via 402 and the second via 403 at least partially overlap, and in the locked state, as... Figure 5 As shown, the first through hole 402 and the second through hole 403 are staggered. The position of the elastic buckle 42 is adjusted by the unlocking component 50 to adjust the relative position of the first through hole 402 and the second through hole 403, so that the pull rope 20 can be locked and unlocked by the relative position of the first through hole 402 and the second through hole 403.

[0054] Furthermore, such as Figure 4 As shown, the unlocking assembly 50 includes a flexible connecting rod 51 and an unlocking switch 52. One end of the flexible connecting rod 51 is connected to the elastic mounting bracket 40; the other end of the flexible connecting rod 51 is connected to the unlocking switch 52. Figure 6 As shown, the unlocking switch 52 includes a handle 521 and a rotating shaft 522. The handle 521 is connected to the rotating shaft 522, and the other end of the flexible connecting rod 51 is connected to the rotating shaft 522.

[0055] The second track assembly 70 may incorporate a spring system 72, allowing the second track assembly 70 to hover at any position. The specific structure of the spring system 72 is not detailed here. Figure 4 In the illustrated embodiment, the second track assembly 70 includes a second track 71, a fixed pulley end cap 73, and a spring system 72. This application does not impose specific limitations on the structure of the second track assembly 70, and will not elaborate further here.

[0056] For example, the working process of the curtain 100 will be described below. Rotating the unlocking switch 52 tightens the flexible connecting rod 51, and the elastic buckle 42 retracts, thus disengaging from the positioning component 10. Simultaneously, the elastic mounting bracket 40 releases the pull cord 20. At this time, the first track component 400 can slide freely along the pull cord 20. After moving to the desired position, releasing the unlocking switch 52 causes the spring 43 to push the elastic buckle 42 back to its original position, locking the pull cord 20. At this point, the first track component 400 is fixed, thus completing the adjustment of the light-blocking position.

[0057] In the above embodiments, the first track assembly 400 uses an embedded elastic mounting bracket 40 to ensure a tight fit between the first track assembly 400 and the window frame, preventing light leakage. The elastic mounting bracket 40 has a locking function. The overall structure of the curtain 100 is simple, reducing manufacturing and transportation costs. The first track assembly 400 can be both fixed and movable, making it suitable for different sun-shading scenarios. The spring system 72 is built into the second track 71. The weight of the spring system 72 is equivalent to the weight of a counterweight, which reduces the need for counterweights and reduces the overall weight of the curtain 100.

[0058] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments are included within the scope of protection of this technical solution.
