[0033] The following is combined with Figure 1-17 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0034] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "end", "front", "back", "middle", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection, etc. commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0036] like Figure 1-4 As shown, a curtain mechanism comprises: a top rail 1, at least one cord winder 2 and a first rotating member 3, a first opening 11 is provided at the lower end of the top rail 1, and a second opening 16 is provided at each end of the top rail 1. Compared with the existing curtain mechanism, since the bottom of the existing curtain mechanism is closed, the cord winder 2 needs to be punched and fixed, which makes the strength of the curtain mechanism lower, and undoubtedly increases the labor intensity and assembly difficulty, which is time-consuming and labor-intensive, and also makes the top rail 1 as a whole unsightly. In this application, by providing a first opening 11 at the bottom of the top rail 1 and opening second openings 16 at both ends of the top rail 1, there is no need to punch holes in the top rail 1 to fix the cord winder 2 and the motor 8. They only need to be put in from the second opening 16 of the top rail 1. Assembly can be achieved without punching holes, reducing assembly difficulty and saving time. Moreover, the end cover 7 is more convenient to fix and can be fixed to the top rail 1 without punching holes in the top rail 1.

[0037] like Figure 17As shown, the bottom of the top rail 1 of the curtain mechanism in the prior art is not opened, and the bottom of the top rail 1 needs to be punched, and then cooperate with the raised part of the bottom of the cord reel 2 to achieve a fixing effect. Once the hole is punched, the fixed position cannot be changed, resulting in the cord reel 2 being unable to move as needed; while the present application can lock and unlock the cord reel 2 through the locking assembly 5, so that the cord reel 2 can move along the direction of the top rail 1 to meet different usage requirements.

[0038] The top rail 1 of the curtain mechanism in the prior art is also provided with end caps 7 on both sides, and the end caps 7 also need to be fixed with screws to the top rail 1 through holes punched at the bottom (see Figure 17 and the present application is provided with a fixing member 6, the fixing member 6 is fixed to the top rail 1, and then the end cover 7 covers the top rail 1 from the side, and fixation is achieved without punching.

[0039] Moreover, the size of the existing curtain mechanism is customized, and the size of the curtain mechanism will affect the position of the punching holes (the number of punching holes and the spacing between holes will be different for different product sizes), which is very inconvenient to assemble. The present application is based on the above-mentioned locking assembly 5 and fixing part 6, which can solve this technical problem without punching holes.

[0040] like Figure 4-8 As shown, at least one cable reel 2 and a first rotating member 3 are provided in the top rail 1, and the first rotating member 3 is provided through the cable reel 2 so that the cable reel 2 can be driven by the first rotating member 3 to rotate relative to the top rail 1. Specifically, the cable reel 2 includes a support 21 and a second rotating member 22 provided in the support 21. The second rotating member 22 can be driven by the first rotating member 3 to rotate relative to the top rail 1. A plurality of rolling assemblies 4 are provided in the support 21 to abut against the second rotating member 22. The second rotating member 22 has a plurality of recessed portions 221 formed along its inner wall. The surface of the first rotating member 3 has a plurality of raised portions 31 formed to cooperate with the recessed portions 221. The recessed portions 211 abut against the raised portions 31, so that the first rotating member 3 can drive the second rotating member 22 to rotate. By providing the rolling assemblies 4, the friction of the second rotating member 22 can be reduced, making the second rotating member 22 roll more smoothly, and can also reduce resistance and noise during use, thereby improving the user experience.

[0041] The support 21 includes a base 211 and a top cover 212 that cooperates with the base 211. The rolling assembly 4 is respectively arranged on both sides of the base 211 and the top cover 212.
