Description

Technical Field

[0001] The utility model relates to a sunshade curtain technology, in particular to a sunshade curtain reel structure. Background Art

[0002] With the popularization of sunroofs on cars, the requirements for sunshades used with supporting sunroofs are increasing. The original sunshade curtain end and the reel assembly are fixed with 3M glue, which is not strong enough. Over time, it is easy to cause the sunshade position to shift, affecting the running position of the sunshade, causing the sunshade to fall off due to lack of synchronization. At the same time, the plastic side strips on the side of the curtain are fixed to the reel with 3M glue. The curtain and plastic side strips are made of different materials and fixed on the same reel, which has unstable performance and is easy to loosen and fall off. Summary of the invention

[0003] The utility model provides a sunshade curtain reel structure which has a simple structure and can effectively ensure stable assembly of curtain fabric and side plastic edge strips on the reel.

[0004] The technical solution adopted by the utility model is: a sunshade curtain roller structure, including a hollow shaft body, an inlay and an end cover, characterized in that: the outer wall of the hollow shaft body is provided with an axially extending card-connecting groove, the card-connecting groove is a convex structure facing the inner cavity of the hollow shaft body by stamping the outer wall of the hollow shaft body, a card-connecting strip for card-connecting curtain cloth is arranged in the card-connecting groove, a plug core is arranged in the middle of the cover body of the end cover, which is directed toward and inserted into the inner cavity mouth of the hollow shaft body, and an edge strip card slot corresponding to the plastic edge strip of the side edge of the card-connecting curtain cloth is provided on the cover edge of the end cover.

[0005] Furthermore, a strip end cap is provided at the head end of the side plastic strip, and the strip end cap is placed inside the cover edge at the strip clamping groove position.

[0006] Furthermore, a plurality of mutually parallel anti-skid ridges and / or anti-skid grooves are arranged on the outer periphery of the fillet.

[0007] Furthermore, a plurality of anti-skid grooves and / or anti-skid ridges which are parallel to each other and correspond to the fillet strips are arranged on the lower groove wall of the card connection groove.

[0008] Furthermore, the outer opening of the card connection slot is closed.

[0009] Furthermore, the cross section of the plug core corresponds to the structure of the inner cavity opening of the hollow shaft body with an inner convex structure.

[0010] Furthermore, the cross section of the edge strip end corresponds to an inward convex structure.

[0011] The utility model forms an inner convex structure by axially pressing downward on the outer wall of a traditional winding shaft body, and clamps an embedding strip in the clamping groove of the inner convex structure. The cooperation of the embedding strip and the clamping groove with multiple ridges and grooves helps to improve the anti-slip effect of the cord cloth clamped in the embedding strip and the clamping groove, and the cord cloth assembly is more stable. The plug core of the end cover cooperates with the inner cavity mouth of the hollow shaft body and the inner convex structure for insertion, and the corresponding insertion is stable and firm, and can prevent rotation and loosening. A side strip clamping groove is provided on the end cover, and the side plastic side strip of the cord cloth is inserted into the side strip clamping groove and limited by the end of the side strip to prevent loosening from the clamping connection with the end cover, which helps to improve the stability and anti-loosening performance of the winding shaft and cord cloth assembly.
