The lower wall in the sunshade curtain rail is also provided with a side rail groove for accommodating side strips of the sunshade curtain.

The middle part of the sunshade curtain sliding block is downwards connected with the sunshade curtain cord fabric side edge strip in the edge strip track groove.

Two lower convex ribs are respectively supported on the lower walls of the sunshade curtain rails at two sides of the side rail groove.

The elastic rib is integrally cast with the slider body or is formed by casting and connecting an elastic metal sheet with the slider body.

The beneficial effects of the utility model are as follows:

the upper and lower convex ribs are tightly abutted against the upper and lower inner walls of the track during running between the middle part of the sliding block body and the sunshade curtain guide rail, the Z-direction limiting points are in surface contact, the running process is free of clamping stagnation, and the Yi Kadu problems of serious left and right shaking and surface contact fit of the sliding block body in the sunshade curtain guide rail can be effectively avoided.

The outer side of the sliding block body and the inner wall of the stay cable through groove of the sunshade curtain guide rail are provided with a gap of 0.1mm, so that the shaking amount in the inner and outer side directions is effectively reduced, and the sliding block body and the guide rail are not blocked when the sunshade curtain guide rail run along with the stay cable;

the inside of the sliding block body is connected with the extension rod in an inserting way through the four-sided elastic rib structure and is in interference fit, the elastic rib elastic butt of the sliding block is utilized to meet the requirements of the inserting way, the locking and the shaking are avoided, the loose inserting of the extension rod is avoided, and the service performance of the sunshade curtain is improved.
