Description

Technical Field

[0001] The invention relates to the technical field of curtains, and in particular to a curtain fixing bracket. Background Art

[0002] At present, projectors are increasingly used in outdoor activities such as camping due to their small size and portability. The screen of the projector is mounted on a screen bracket to better provide a display carrier for the projected image.

[0003] However, the existing curtains have the following defects:

[0004] (1) During the unwinding process of the existing curtain, there is no limit or load-bearing mechanism at the bottom of the curtain body, so it is easy to shake back and forth, which reduces the practicality.

[0005] (2) When the existing winding assembly uses a chain drive, the chain is prone to loosening after long-term use, which affects the transmission effect. Utility Model Content
