[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0023] like Figures 1-6 The curtain head shown includes a first head 1 with a planetary gear 3 and a second head 2 used in conjunction with the first head 1. The second head 2 includes an L-shaped bracket 21 for fixing to the wall and a mounting bracket 22 fixed on the bracket 21. The mounting bracket 22 is provided with a mounting groove 23 and also includes a roller 24 and a housing 26 that are matched with the mounting groove 23. The mounting bracket 22 also includes a fan-shaped block 25 that is hinged and swings relative to it. The mounting groove 23 is composed of the fan-shaped block 25 and the mounting bracket 22. In this embodiment, when the curtain head is in use, the end of the roller 24 can be inserted into the mounting groove 23 formed by the fan-shaped block 25 and the mounting bracket 22. After the fan-shaped block 25 swings and engages with the mounting bracket 22, it forms an axial limit on the roller 24. At this time, the roller 24 can rotate circumferentially on the bracket 21. The sleeve 26 connected to the roller 24 is inserted into the curtain track. The smooth rotation of the roller 24 and the mounting bracket 22 facilitates the rolling out and rolling up of the curtain. After the roller 24 is limited and locked by the mounting bracket 22, the operation is quiet and safe.

[0024] As a further feature of the above solution, one end of the roller 24 has a mushroom cap 241 located in the mounting groove 23, and the other end has a hook 27 that passes through the housing 26. The roller 24 has a stepped portion 29, and the housing 26 also has a spring 28. The spring 28 is fitted inside the roller 24, and its two ends abut against the stepped portion 29 and the bottom of the inner cavity of the housing 26, respectively. The length of the roller 24 is greater than the depth of the inner cavity of the housing 26. The spring 28 is used to drive the housing 26 to move away from the bracket 21.

[0025] As a further feature of the above scheme, the mounting bracket 22 is provided with a hinge shaft 221, the sector block 25 is provided with a hinge groove that matches the hinge shaft 221, the mounting bracket 22 is provided with a first notch 224, the sector block 25 is provided with a second notch 225, and the mounting groove 23 formed by the first notch 224 and the second notch 225 has a structure with a larger inner opening and a smaller outer opening.

[0026] As a further feature of the above solution, the mounting bracket 22 is provided with a buckle groove 222, and the sector block 25 is provided with a hook lock 223. The hook lock 223 engages with the buckle groove 222 when the sector block 25 swings to form the mounting groove 23.

[0027] As a further feature of the above solution, the bracket 21 is provided with fixing holes 213. The fixing holes 213 are respectively provided on the two plates of the L-shaped bracket 21 at a 90-degree angle. The two sets of fixing holes 213 allow users to freely choose the fixing method and angle of the bracket 21.

[0028] As a further provision of the above scheme, a retaining plate 211 is provided on the bracket 21 on one side of the first cutting head 1, and a cross slot 212 is provided on the first cutting head 1. The retaining plate 211 is matched and inserted into the cross slot 212. After the retaining plate 211 is inserted into the cross slot 212, it can form a circumferential limit for relative rotation between some components of the first cutting head 1, namely the inner shaft of the planetary gear 3 and the star gear and the sun gear.

[0029] As a further provision of the above solution, the bracket 21 and the mounting bracket 22 are provided with screw mounting holes 20. The screw mounting holes 20 are arranged in four circumferentially evenly. The mounting bracket 22 is fixed to the bracket 21 by bolts passing through the screw mounting holes 20. When the bracket 21 and the mounting bracket 22 are installed, the bolts fix at least two diagonally opposite screw mounting holes 20.

[0030] refer to Figures 1-6 The curtain head of this utility model shown consists of two heads, namely a first head 1 and a second head 2. The first head 1 has a planetary gear 3 and a bead chain structure, while the second head 2 includes a bracket 21 and a housing 26. Figure 2 and Figure 3 The bracket 21 shown is fixed with a mounting bracket 22 via screw mounting holes 20. In this embodiment, the mounting bracket 22 includes a sector-shaped block 25 hinged to it. The sector-shaped block 25 has a second notch 225, and the mounting bracket 22 has a first notch 224. Together, they form a mounting groove 23. Notably, a roller 24 is also inserted through the housing 26. One end of the roller 24 has a mushroom cap 241. The mushroom cap 241, with a ring groove at its front end, extends into the mounting groove 23, whose opening is smaller than the inner cavity, for installation. Figure 1 The roller 24 shown is axially fixed relative to the mounting bracket 22. A spring 28 is further provided inside the housing 26. The other end of the roller 24 passes through the housing 26 and is provided with a hook 27 to restrict its disengagement. The two ends of the spring 28 abut against the stepped part 29 of the roller 24 and the bottom surface of the inner cavity of the housing 26, respectively, driving the housing 26 to move away from the bracket 21. Due to the restriction of the hook 27, it cannot disengage relative to the roller 24. Thus, after the bracket 21 is fixed in front, the housing 26 can extend a certain length relative to the bracket 21 and be inserted into the curtain track tube. This allows for adaptive use at curtain installation frames where there are small errors in the manufacturing and measurement of width dimensions.

[0031] The curtain head in this embodiment is equipped with a relatively long roller 24 that can adjust the extension and retraction of the second head 2, and has a hook 27 to prevent it from falling off. It is quiet and safe to operate, and can be installed on the side, top, or both ends, making it easy to measure, install, and maintain.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
