AI Technical Summary
Existing curtain rolling mechanisms are prone to deviation when rolling up curtains, resulting in complex structures and increased weight.
Rigid guide reinforcement strips are installed on the curtain fabric and connected to the connecting section by gluing or sewing. This ensures that the guide reinforcement strips are set parallel to the curtain rolling device and are connected to the curtain rolling device by connecting ropes, thereby improving the strength and stability of the curtain fabric at the connecting section.
It effectively avoids the problem of curtains shifting when rolled up, while maintaining a simple structure and not adding extra weight.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtains, and in particular to a curtain roll-up structure. Background Technology
[0002] Many existing curtains use a curtain roller shutter mechanism (either a tubular motor or a mechanical roller shutter driven by a beaded cord) to roll up and unroll the curtain fabric, hence the name roller blinds. However, existing curtains have a problem: because the curtain fabric is relatively soft, if the roller shutter mechanism is directly connected to the fabric or connected via a cord, the fabric may shift off-center when the mechanism rolls it up. To address this, current solutions involve complex guide and limiting mechanisms on the roller shutter mechanism to guide the fabric, or heavy-duty trim strips at the bottom of the fabric, resulting in a complex and heavy curtain structure.
[0003] In view of the above problems, it is necessary to study a curtain roll-up structure that is simple in structure and can prevent the curtain fabric from going off-center when rolled up. Utility Model Content
[0004] The purpose of this utility model is to provide a curtain rolling structure that is simple in structure and can prevent the curtain fabric from going off-center when rolling it up.
[0005] To achieve the above objectives, the solution of this utility model is:
[0006] A curtain rolling structure includes a curtain rolling device and a curtain fabric; the curtain fabric includes a flexible fabric body and a number of rigid guide reinforcing strips, one side of the fabric body has a connecting section connected to the curtain rolling device, and each guide reinforcing strip is spaced apart in the connecting section, and each guide reinforcing strip is arranged parallel to the curtain rolling device.
[0007] The guide reinforcement strip is made of plastic or metal.
[0008] The guide reinforcement strip is bonded to the connecting section or sewn together with sutures.
[0009] The various reinforcing guide strips of the curtain fabric are evenly spaced at the connecting section.
[0010] The spacing between adjacent guide reinforcement strips is 1±0.5mm.
[0011] The width of the guide reinforcement strip is 2±0.5mm.
[0012] The connecting section is connected to the curtain rolling device via at least two connecting ropes.
[0013] The curtain rolling device uses a tubular motor.
[0014] By adopting the above solution, this utility model incorporates several spaced-apart reinforcing guide strips at the connecting section of the fabric body, and these reinforcing guide strips are of a rigid structure. This effectively enhances the strength of the portion of the curtain fabric corresponding to the connecting section, ensuring that the portion of the curtain fabric corresponding to the connecting section does not deviate when the curtain rolling device rewinds it. After the portion of the curtain fabric corresponding to the connecting section is stably rolled into the curtain rolling device, it can guide the remaining portion of the curtain fabric, ensuring that the remaining portion of the curtain fabric is also stably rolled into the curtain rolling device.
[0015] As can be seen from the above, this utility model can prevent the curtain fabric from going astray when it is rolled up, and the structure is simple as long as a guide reinforcement strip is set on the curtain fabric. Attached Figure Description

[0026] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0027] like Figures 1 to 4 As shown, this utility model discloses a curtain rolling structure, which includes a curtain rolling device 1 and a curtain fabric 2; the curtain fabric 2 includes a flexible fabric body 21 and a number of rigid guide reinforcing strips 22. One side of the fabric body 21 has a connecting section 211 connected to the curtain rolling device 1. Each guide reinforcing strip 22 is spaced apart in the connecting section 211, and each guide reinforcing strip 22 is arranged parallel to the curtain rolling device 1.
[0028] This invention features a plurality of spaced-apart reinforcing guide strips 22 on the connecting section 211 of the fabric body 21. These reinforcing guide strips 22 are rigid in structure. This effectively enhances the strength of the portion of the curtain fabric 2 corresponding to the connecting section 211, preventing deviation of this portion when the curtain roll-up device 1 retracts it. Once this portion is stably rolled into the curtain roll-up device, it guides the remaining portion of the curtain fabric, ensuring its stable roll-up as well. As can be seen, this invention prevents deviation of the curtain fabric 2 during retraction, and its structure is simple, requiring only the reinforcing guide strips 22 on the curtain fabric 2.
[0029] In an embodiment of this utility model, each guide reinforcing strip 22 of the curtain fabric 2 can be equally spaced on the connecting section 211, the spacing D2 between adjacent guide reinforcing strips 22 can be 1±0.5mm, and the width D1 of the guide reinforcing strip 22 can be 2±0.5mm.
[0030] In embodiments of this invention, the guide reinforcement strip 22 can be made of plastic, making it both rigid and lightweight; alternatively, the guide reinforcement strip 22 can be made of metal. The guide reinforcement strip 22 and the connecting section 211 can be connected by adhesive bonding or by sewing.
[0031] In an embodiment of this utility model, the connecting segment 211 is connected to the curtain rolling device 1 via at least two connecting ropes 3, so that the curtain rolling device 1 applies force evenly to the curtain fabric 2.
[0032] In the embodiments of this utility model, the curtain rolling device 1 adopts a tubular motor; it should be noted that the curtain rolling device 1 can also adopt a mechanical rolling device driven by a beaded string.
[0033] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
