Detailed Description

For a better understanding and appreciation of the objects, features, and advantages of the utility model, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

Firstly, please refer to fig. 1 and 2, a rolling structure 10 includes a rotating shaft 11, a curtain cloth 12, a winding outer tube 13, a bead chain device 14, a driven shaft 15 and two brackets 16, wherein the outer surface of the rotating shaft 11 is provided with a rough layer 111, the rough layer 111 is formed by surface treatment or attachment, the upper and lower ends of the curtain cloth 12 are provided with a first weight rod 121 and a second weight rod 122, the curtain cloth 12 is movably spanned on the rotating shaft 11, the first and

second weight rods

121 and 122 are arranged downwards, the cross section of the winding outer tube 13 is C-shaped and is provided with a braking portion 131, two end edges of the braking portion 131 are both bent inwards and obliquely to form a fan-shaped space for the braking portion, a through outlet 133 is formed between the two abutting portions 132, the opening width of the through outlet 133 is smaller than that of the rotating shaft 11 and the first abutting portion 132, The diameters of the two

balance weight tubes

121 and 122, the ball chain device 14 and the driven shaft 15 are respectively assembled at two ends of the rotating shaft 11, and the ball chain device 14 is used to drive the rotating shaft 11 to rotate, and the outer sides of the ball chain device 14 and the driven shaft 15 are respectively provided with the bracket 16 in a rotatable manner.

The two surfaces of the curtain 12 are different colors, patterns or coatings to form a first surface 123 and a second surface 124.

Referring to fig. 1, 2, 3 and 4, the curtain cloth 12 is disposed across the rotating shaft 11, the winding outer tube 13 is disposed to cover the braking portion 131 downward and axially outside the rotating shaft 11, the through-out opening 133 is provided for passing through two ends of the curtain cloth 12, the first and

second weight rods

121 and 122 form a sinking and hanging state, and the curtain cloth 12 is pushed by the end edges of the two abutting portions 132 when passing through the through-out opening 133 to allow the curtain cloth 12 to be firmly attached to the rotating shaft 11, the bead chain device 14 and the driven shaft 15 are respectively mounted at two ends of the rotating shaft 11, the two ends of the bead chain device 14 and the driven shaft 15 are both rotatably mounted with the bracket 16, and the rolling structure 10 can be mounted on a predetermined wall surface through the two brackets 16, thereby completing the rolling structure.

In addition, the top ends of the two brackets 16 are both provided with a combination portion 161 by bending inwards, so that the two brackets 16 can be directly installed on a preset wall surface through the combination portion 161; in addition, an upper rail rod 17 can be installed through the two combination parts 161, and then the upper rail rod 17 is installed on a preset wall surface.

Referring to fig. 1 and 3, the rolling shutter structure 10 utilizes the bead chain device 14 to drive the rotating shaft 11 to rotate, and then utilizes the rotating shaft 11 to drive the curtain cloth 12 to move up and down, because the first and second

balance weight rods

121 and 122 at the two ends of the curtain cloth 12 both form free ends and hang down, when the bead chain device 14 is pulled and the rotating shaft 11 is driven, the curtain cloth 12 will not be wound on the rotating shaft 11, so that the curtain cloth 12 can be completely unfolded to form a single-layer use state, or has an overlapped part to form a double-layer use state and adjust the use state of indoor light irradiation.

Secondly, as shown in fig. 1 and fig. 3 to 7, when the bead chain device 14 drives the rotating shaft 11 clockwise to rotate and adjust the curtain fabric 12, the first weight rod 121 of the curtain fabric 12 is displaced upward, and the second weight rod 122 is displaced downward, when the curtain fabric 12 is completely unfolded, the first weight rod 121 abuts up against the winding outer tube 13, and the first surface 123 of the curtain fabric 12 is unfolded inward, and the second surface 124 is relatively unfolded outward, so that when the rotating shaft 11 is continuously driven clockwise by the bead chain device 14 to rotate, the first weight rod 121 is embedded into the stopper 131 to be limited and positioned, and abuts against and pushes a abutting portion 132 to drive the winding outer tube 13 to rotate clockwise, thereby further winding the curtain fabric 12 upward outside the winding outer tube 13, forming a winding state of the curtain fabric 12 and a single-layer dimming effect.

On the contrary, when the ball chain 14 drives the rotating shaft 11 to rotate counterclockwise and adjusts the curtain cloth 12, as shown in FIGS. 8, 9 and 10, the second weight bar 122 of the curtain 12 is displaced upward and the first weight bar 121 is displaced downward, so that when the curtain 12 is fully deployed, the second weight bar 122 is up against the winding outer tube 13, and spreads the second surface 124 of the curtain 12 inwardly, the first surface 123 is relatively unfolded outwards, so as to change the presenting manner of the curtain cloth 12, and when the rotating shaft 11 is continuously driven to rotate anticlockwise by the bead chain device 14, the second weight rod 122 is embedded into the stopper 131 for limiting and positioning, and pushes against the other abutting portion 132 to drive the winding outer tube 13 to rotate counterclockwise, so as to further wind the curtain cloth 12 up outside the winding outer tube 13, thereby forming a winding state of the curtain cloth 12 and a single-layer dimming effect.

With the structure of the above embodiment, the following benefits can be obtained: the rolling curtain structure 10 of the utility model is to straddle the curtain cloth 12 on the rotating shaft 11, and the first and second

balance weight rods

121, 122 at both ends of the curtain cloth are both downward disposed, when pulling the bead chain device 14 and driving the rotating shaft 11, the curtain cloth 12 will not be wound on the rotating shaft 11, so that the curtain cloth 12 has single-layer and double-layer usage status, and further by changing the driving direction of the bead chain device 14, the curtain cloth 12 has the single-layer double-sided presentation effect, increasing the variability of structure usage, contributing to improving the household atmosphere, and in addition, the purpose of winding the curtain cloth 12 can be achieved by the winding outer tube 13, and the practicability of the rolling curtain structure 10 is improved.
