The present invention is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the scope of protection of the present invention.

[0036] (Example 1)

[0037] As shown in Figures 1-6, a manually retractable curtain includes a track 1, curtain slats 2, and a sliding stop mechanism 3. The track 1 is retractable, and the curtain slats 2 are arranged in parallel with each other, slidingly connected to the track 1 along its length. The curtain fabric is hung on curtain hooks 2-3 at the lower ends of the curtain slats 2. The sliding stop mechanism 3 is located between two adjacent curtain slats 2. When the curtain is opened or closed, the upper curtain slat 2 drives the lower curtain slat 2 to slide along the track 1.

[0038] Specifically, the track 1 includes an outer rail 1-1, a first inner rail 1-2, and a second inner rail 1-3. The outer rail 1-1, the first inner rail 1-2, and the second inner rail 1-3 are all open at the bottom, and a cavity is formed inside. The tops of the outer rail 1-1 and the first inner rail 1-2 are provided with mounting portions for easy installation. The first inner rail 1-2 is located in the cavity of the outer rail 1-1 and is slidably connected to the outer rail 1-1 along the length direction of the outer rail 1-1. There are two cavities of the first inner rail 1-2 arranged in parallel, and a second inner rail 1-3 is arranged in each cavity. The second inner rail 1-3 is slidably connected to the first inner rail 1-2 along the length direction of the first inner rail 1-2. As a preferred embodiment of this embodiment, the length of the second inner rail 1-3 is not less than the length of the outer rail 1-1. When installing the track 1, the track 1 can be adjusted according to the size of the customer's window. There is no need to specially customize the length, and the adaptability is strong. In addition, due to the scalable design of the track 1, the volume of packaging and transportation can be reduced, reducing transportation costs.

[0039] A track roller 2-1 is provided on the upper part of the curtain piece 2, and the track roller 2-1 slides in the track 1. Specifically, in this embodiment, when the curtain is retracted, the track roller 2-1 is divided into two groups, which are respectively located in the two cavities of the first inner rail 1-2. When the curtain is opened, the track roller 2-1 slides in its respective track, moving from the first inner rail 1-2 to the corresponding second inner rail 1-3. The end of the outer rail 1-1 away from the first inner rail 1-2 is flush with the end of the second inner rail 1-3 away from the first inner rail 1-1. Since the second inner rail 1-3 is provided, the track roller 2-1 will not deviate from the original track during the sliding process. If the second inner rail 1-3 is not provided, the track roller 2-1 will enter the outer rail 1-1 when the curtain is opened, and the bottom opening of the outer rail 1-1 is too large, which can easily cause the track roller 2-1 to derail. Therefore, providing the second inner rail 1-3 can make the track roller 2-1 slide only in the first inner rail 1-2 and the second inner rail 1-3.

[0040] Furthermore, a sliding groove 2-2 is provided on the side of each curtain piece 2, and the sliding limiting mechanism 3 includes a limiting block 3-1 and a sliding block 3-2. The limiting block 3-1 is fixed in the sliding groove 2-2 of the previous curtain piece 2, and part of the sliding block 3-2 is provided in the sliding groove 2-2 of the next curtain piece 2. When the curtain is opened, the limiting block 3-1 and the sliding block 3-2 abut and get stuck, and the previous curtain piece 2 can drive the next curtain piece 2 to slide in the track 1. At this time, there is an overlapping portion between adjacent curtain pieces 2. As a preferred solution of this embodiment, the position of the sliding block 3-2 in the sliding groove 2-2 of the next curtain piece 2 can be adjusted to adjust the length of the overlapping portion, so as to adapt to the length of the track 1, so that the overlapping portion remains consistent after the curtain piece is opened, and it is more beautiful after the curtain is opened. The curtain piece 2 adopts a modular design and does not need to be specially customized in length.

[0041] A sliding wheel 3-2-1 is provided on the sliding block 3-2, and the sliding wheel 3-2-1 is located in the sliding groove 2-2 of the adjacent upper curtain sheet 2. The sliding wheel 3-2-1 keeps the distance between the adjacent curtain sheets 2 unchanged.

[0042] For ease of understanding, the following describes the specific operation of the manually retractable curtain in this embodiment: After the track 1 is installed, when the curtain is extended, the user controls the movement of the upper curtain slat 2. When the stopper 3-1 on the upper curtain slat 2 hits the sliding block 3-2 of the lower curtain slat 2, the lower curtain slat 2 is pulled open. When the curtain is retracted, the track roller 2-1 of the upper curtain slat 2 hits the roller of the lower curtain slat 2-1, thereby retracting the lower curtain slat 2.

[0043] (Example 2)

[0044] As shown in Figure 7, this embodiment, compared to Example 1, is equipped with a curtain fabric hanging piece 4. A curtain hook 2-3 is provided at the lower end of the curtain slat 2, on which a curtain fabric hanging piece 4 is hung. The lower end of the curtain fabric hanging piece 4 is hung with a curtain shifting fabric. Specifically, the curtain fabric hanging piece 4 is provided with an upper hook 4-1 and a lower hook 4-2. The curtain hook 2-3 cooperates with the upper hook 4-1, and the curtain shifting fabric is hung on the lower hook 4-2. Curtain end caps are provided at both ends of the curtain slat 2 to prevent the curtain fabric hanging piece 4 from detaching from the curtain slat 2 during use. The curtain shifting fabric is hung on the curtain slat 2 via the curtain fabric hanging piece 4, making it easy to remove the curtain shifting fabric.

[0045] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
