Technical Field
[0001] The utility model relates to the technical field of rolling curtains, in particular to a noise-reducing and anti-stuck rolling curtain rotating component. Background Art
[0002] Roller blinds are one of the window decoration products. They are made by processing the curtain fabric with resin and rolling it into a roller shape. They are raised and lowered by a rope or chain. They are easy to operate and have a beautiful and simple appearance. They make the window frame look clean and neat, and the whole room looks spacious and simple. Roller blinds mainly include electric roller blinds, beaded roller blinds, and spring roller blinds. Roller blinds have many advantages such as beautiful and simple appearance, strong and durable structure, etc. Roller blinds are suitable for many places, such as business office buildings, hotels, restaurants, offices, homes (used as gauze curtains), especially for large-area glass curtain walls. When the roller blind fabric is lowered, it can soften the indoor light and avoid the trouble of direct sunlight, achieving a good sunshade effect. When the roller blind is raised, its volume is very small, so it is not easy to be noticed. Roller blind fabrics include semi-shading roller blinds, semi-transparent roller blinds, and full-shading roller blinds. The latest launches include UV-proof roller blinds, waterproof roller blinds, and easy-to-decontaminate engineering roller blind fabrics. The control methods are: manual roller blinds, electric roller blinds, spring semi-automatic roller blinds, etc. It can be used for office building curtains, school curtains, hotel curtains, and guesthouse curtains.
[0003] At present, when roller blinds on the market are in use, especially electric roller blinds, motors are required to drive the roller blinds. In actual use, when the electric roller blinds are in use, a motor and a roller tube are usually required to be installed on the top to retract and release the sunshade fabric. At the same time, guide rails are installed on both sides of the window to prevent problems such as bottom wrinkles when the sunshade fabric is released. Because the guide groove outside the guide rail is exposed to the outside, the guide groove is easily blocked by foreign objects, which may cause the subsequent sunshade fabric to fall stuck or even unable to fall.
