The slewing component 2 and the control component 3 are respectively arranged at two ends of the roller 1. The control component 3 comprises an inner shaft 31 and a rotating sleeve 32 sleeved on the outer side of the inner shaft 31. The rotating sleeve 32 can be relatively rotatably sleeved on the outer side of the inner shaft 31. The rotating sleeve 32 comprises a connecting portion 322 for cooperating with the roller 1. The roller 1 and the connecting portion 322 are connected to each other. The inner shaft 31 is fixedly connected to the rotating sleeve 32, one end of the inner shaft 31 is provided with an external gear portion 311 arranged toward the rotating sleeve 32, an internal gear portion 321 is provided on the rotating sleeve 32 at one end close to the external gear portion 311, a plurality of planetary gears 33 meshing with the external gear portion 311 and the internal gear portion 321 are provided between the external gear portion 311 and the internal gear portion 321, and also includes a sprocket 34, a plurality of connecting shafts 341 adapted to the planetary gears 33 are provided on the sprocket 34, the planetary gears 33 are rotatably arranged on the connecting shafts 341, the sprocket 34 is provided with a chain rope for controlling its rotation, and the speed ratio of the sprocket 34 to the reel 1 is 1 to 1 or more. In this embodiment, a rotating component 2 and a control component 3 are respectively provided at both ends of the reel 1 to cooperate with the reel 1. Through the cooperation of the gears between the sprocket 34 and the reel 1, when the sprocket 34 is controlled to rotate one circle, the reel 1 rotates a greater stroke, and the reel 1 can be controlled to rotate quickly to achieve rapid lifting and lowering. The rotating component 2 can balance the gravity of the curtain and reduce the rotation resistance of the sprocket 34. It is more labor-saving to use and can make the curtain stay at any height.

[0029] See also Fig.10 and Fig.11 The rotating part 2 includes a fixed shaft 21 and an outer rotating shaft 22 sleeved outside the fixed shaft 21. Six spring fixing areas 23 are arranged between the fixed shaft 21 and the outer rotating shaft 22. A spiral spring 24 is arranged in each of the spring fixing areas 23. The spiral spring 24 is wound on the fixed shaft 21, and its two ends are respectively fixed on the fixed shaft 21 and the outer rotating shaft 22. One end of the reel 1 is sleeved on the outer rotating shaft 22.

The spiral spring 24 has a small rotational force in the initial state. As the curtain continues to fall, it gradually rotates and tightens, and the rotational force gradually increases, so that it can achieve balance with the increasing weight of the curtain.

[0030] See also Figure 1 and Figure 4The control component 3 further comprises a sheath 36 which is covered outside the sprocket 34 and is fixedly connected to the inner shaft 31. The sheath 36 is used to limit the chain rope.

[0031] See also Figure 5 and Fig.10 The inner shaft 31 and the end of the rotating component 2 away from the reel 1 are both provided with a plug-in fixing portion 101, which is used to connect with a fixing bracket, so as to fix the present application on a wall. Embodiment 2:

[0032] See also Figure 5 , Figure 8 and Fig. 9 The rotating sleeve 32 includes a first sleeve 323 and a second sleeve 324 sleeved outside the first sleeve 323. The outer gear part 311 is arranged on the first sleeve 323, and the connecting part 322 is arranged on the second sleeve 324. The first sleeve 323 and the second sleeve 324 are respectively provided with a mutually meshing positioning connecting groove 3231 and a positioning connecting block 3241. The second sleeve 324 has a variety of specifications. The connecting part 322 on the second sleeves 324 of different specifications has different diameters. By replacing the second sleeves 324 of different models, the connection with various reels 1 can be realized. The positioning connecting groove 3231 and the positioning connecting block 3241 are directly connected in an axially movable manner but not in a rotatable manner. The two cooperate to prevent the first sleeve 323 and the second sleeve 324 from rotating relative to each other.

[0033] Working process of this utility model:

[0034] The utility model discloses a curtain control structure capable of rapid lifting and labor-saving. During operation, the curtain is wound on a reel 1, and a rotating component 2 and a control component 3 at both ends are respectively fixed to a wall. The sprocket 34 is controlled to rotate by a chain rope. The sprocket 34 drives the planetary gear 33 to rotate. The planetary gear 33 cooperates with an inner gear portion 321 and an outer gear portion 311 to drive a rotating shaft sleeve 32 to rotate. The rotating shaft sleeve 32 drives the reel 1 to rotate, thereby driving the curtain to be lifted and lowered. The rotating component 2 can provide a winding force for the reel 1. The cooperation of a multi-volute spring 24 can better balance the gravity of the curtain, and the volute spring 24 can be selected to be increased or decreased according to demand. The volute spring 24 has a small rotational force in the initial state. As the curtain continues to descend, it gradually rotates and tightens, and the rotational force gradually increases, thereby achieving a balance with the increasing gravity of the curtain.
