Wind-resistant sun-proof blind

Abstract

The present invention provides a wind-resistant sun-proof blind in the field of mechanical technology, which addresses poor wind resistance of the conventional blinds. The wind-resistant Sun-proof blind of the invention comprises a curtain cloth, a window cover and a reel pipe assembly ratably mounted within the window cover, in which the curtain cloth is wound outside of the reel pipe assembly, each of both ends of the window cover has a downward lateral rail fixedly connected therewith, and the side of the lateral rail facing to the curtain cloth has a longitudinal opening. Two symmetrically disposed lock bars are mounted within the lateral rail along the longitudinal direction, a gap is formed between the said two lock bars, and the upper opening of the gap is in communication with the window cover. Two lateral edges of the curtain cloth extend into the inner cavity of the lateral rail and are transversely fixedly connected with a flexible positioning element after passing through the longitudinal opening of the lateral rail on the same side and the gap between the said two lock bars respectively. The reel pipe assembly has two symmetrically disposed annular grooves and when the curtain cloth is wound around the reel pipe, both lateral edges of the curtain cloth are wound at the corresponding annular grooves respectively, and the outer diameter of the positioning element is larger than the width of the gap between the two lock bars. The present invention has advantages by providing a firm and reliable structure, a good guide nature and strong wind resistance.
