Description

Technical Field

[0001] The utility model relates to the technical field of folding fans, in particular to a folding fan with no welt edging. Background Art

[0002] A folding fan, also known as a folding fan, a gathered-bone fan, etc., is an ancient and widely popular traditional Chinese handicraft. It originated in the Han Dynasty of China and was popular in the Song Dynasty. It consists of a fan surface, fan bones and a fan handle. Its unique feature is that it can be folded and stored, which is convenient for carrying and use. The fan surface of a folding fan is usually made of materials such as paper, silk, cloth, etc., and often painted with exquisite calligraphy, paintings or patterns, showing strong Chinese cultural characteristics. The fan bones are mostly carved from materials such as bamboo, wood, animal bones, ivory, etc., which are both beautiful and strong. A folding fan not only has practical value for cooling and repelling mosquitoes, etc., but also contains profound cultural connotations. It is often used as a plaything for literati and scholars, symbolizing grace and temperament. Nowadays, the folding fan has become an important representative of Chinese traditional culture and is deeply loved and collected by people at home and abroad.

[0003] Chinese Patent CN217644709U. The utility model relates to the technical field of folding fans, especially to a folding fan structure, including a hollow shaft and a fan surface. One end of the hollow shaft is fixedly connected with a first limiting plate. The inner wall of the hollow shaft is provided with threads, and a threaded rod is threadedly connected to the inner wall of the threads. One end of the threaded rod is fixedly connected with a second limiting plate. The advantages of the utility model are as follows: Through the cooperative setting of the threads, the threaded rod, the second limiting plate, the large bones, the small bones, the fixing grooves, the first magic tape and the second magic tape, when the fan surface is damaged, it is convenient to remove the fan surface for replacement. When the large bones or small bones are damaged, it is convenient to remove the damaged large bones or small bones and replace them. Thus, the folding fan structure is convenient for replacing the damaged fan surface and fan bones. When a certain part of the large bones, small bones or fan surface is damaged, only the damaged part needs to be replaced, avoiding the situation that the fan surface or fan bones of the traditional folding fan structure cannot be used continuously after being damaged, and saving resources.

[0004] However, the welt edging part of some existing folding fans is prone to cracking and damage. This defect is mainly due to the limitations of the welt edging materials and processes, as well as natural wear and external forces during long-term use. In the production of traditional folding fans, the welt edging is usually used to fix the fan blades and enhance the overall structural stability. However, since the welt edging often uses relatively fragile or easily aged materials, such as glue or weak fabric edges, they are prone to crack or fall off under conditions such as frequent opening and closing, friction and temperature changes. In addition, improper usage habits, such as folding or dropping the folding fan with excessive force, will also accelerate the damage of the welt edging. Once the welt edging cracks or falls off, it will not only affect the appearance beauty of the folding fan, but also cause the fan blades to scatter, unable to be normally unfolded or folded up, and even scratch the user's hand seriously in severe cases.
