[0002] Nowadays, with the advancement and development of science and technology, roller blinds have been widely used in residential buildings, apartments, office buildings, and even in transportation vehicles such as trains and high-speed trains. The current roller blinds are usually pull-cord type roller blinds. The user pulls the pull cord to lower or raise the curtain body, and then uses a locking mechanism to keep the curtain body in the desired position.
[0003] During use, the pull cord type roller blinds in the prior art have a plastic pull cord. If the curtain body of the pull cord roller blinds is large, the pull cord is prone to breakage, and the device cannot be used any more. The existing push-pull curtains roll up the curtains inside the device, but the pulled-out curtains are not easy to reset, so that the curtains cannot be retracted into the device and piled up outside, occupying space and being unsightly. At the same time, the roller blinds on the train will swing left and right due to the shaking of the train body, which is inconvenient to use. The roller blinds in the prior art can no longer meet the needs of contemporary people. Utility Model Content
