Description

Technical Field

[0001] The utility model relates to a rolling blind, in particular to a rolling blind with a curtain body that is easy to replace, so as to facilitate consumers to disassemble, assemble and replace the rolling blind by themselves, thereby improving the variability of the use of the rolling blind. Background Art

[0002] Nowadays, indoor spaces such as homes and offices often have curtains installed on windows to block sunlight and protect privacy. As the curtains are used for a long time, they are often stained with dust or stains or need to be replaced due to damage. In addition, users may also need to replace curtains due to changes in interior decoration or simply want to adjust the color and pattern of the curtains.

[0003] However, in the existing curtain structure, the curtain surface is often fixedly adhered to the transmission rod of the upper beam. Therefore, when the curtain needs to be replaced due to the above or other possible situations, the user can only choose to replace the entire set of curtains. However, at this time, the braking system of the curtain is often still in good condition. Therefore, when the entire set of curtains is replaced, not only the braking system that works well must be discarded, resulting in an increase in the amount of waste and a waste of resources, but also because the braking system accounts for a relatively large proportion of the curtain cost, the user's replacement cost remains high. Obviously, there is still room for improvement.

[0004] In view of this, the inventor of the present invention has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical and reliable present invention. Utility Model Content
