Description

Technical Field

[0001] The present application relates to the technical field of shading curtains, and in particular to a window shading curtain. Background Art

[0002] Window shades are curtain systems used to block sunlight, regulate light, and protect privacy. Their primary functions include shading, heat insulation, and privacy, making them suitable for a variety of indoor environments, such as homes and offices.

[0003] Patent publication number CN102406418A discloses an outdoor sunshade curtain, comprising a roller blind made of anti-fouling fabric. A reel is connected to the top of the curtain, which is attached to a cable. The curtain can be retracted and extended by controlling the cable. Fabric buckles are mounted on the left and right sides of the curtain, with side rails connected to the reel arranged vertically on the left and right sides. The fabric buckles are locked in the side rails and can roll up and down along the rails. A bottom rail is mounted on the bottom of the curtain, which can slide up and down along the side rails. This allows the fabric buckles to roll up and down in the side rails, while the bottom rail slides up and down in the side rails, preventing the curtain from being blown away by the wind. This significantly enhances the curtain's wind resistance, giving it a wind resistance rating of Class 10.

[0004] However, since the sunshade curtain is installed on the windowsill, when the bottom rail is lowered, the bottom rail drives the roller blind to unfold. At this time, the bottom rail is prone to hit the window sill surface due to excessive force. Over time, the bottom rail will be deformed and damaged, affecting the appearance and service life of the bottom rail. Utility Model Content
