Detailed Description

Fixed stop gear when foldable thing curtain that hides folds, see figure 1, it includes the both sides outer tube 2 of connecting through pivot structure 1, the corresponding outside end correspondence of both sides outer tube 2 is provided with end cover 3, two end covers 3 are provided with at least one screw guide way 4 respectively on the terminal surface in opposite directions that the folding was accomplished, the surface that the screw guide way 4 was corresponding to orientation of one of them end cover 3 is provided with sand grip 5, the end of going up sand grip 5 is provided with turns up and colludes 6, turn up to collude 6 and stretch out in the screw guide way 4 that corresponds of another end cover 3, screw 7 sets firmly in the corresponding position of outer tube 2, screw 7 arranges in the screw guide way 4 that corresponds, be provided with guide spring 8 between the end wall of the inner chamber of end cover 3 and the tip of outer tube, end cover 3 can be along the linear.

Two screw guide grooves 4 which are arranged in parallel are arranged on the corresponding end face of each end cover 3, two upper convex strips 5 are arranged at the outer end positions of one end cover 3 corresponding to the screw guide grooves 4 of the other end cover, and a corresponding outward-turning hook 6 is arranged at the tail end of each upper convex strip 5;

the stop part at the outer end of the outward turning hook 6 is divided into an arc transition structure 61, so that the outer surface structure of the end cover 3 is ensured not to be damaged;

the upper convex strip 5 is an oblique guide strip which gradually shrinks inwards from the position close to the surface of the end cover to the position far away from the surface of the end cover 3, and the outer end stopping part 61 of the outward turning hook 6 does not protrude outwards from the bottom initial position of the upper convex strip 5, so that the two end covers 3 are mutually matched, limited and locked;

the center of the outer end face of each end cover 3 is provided with a convex positioning 9, and the convex positioning 9 is used for propping against an inner groove corresponding to the vehicle body, so that the installation of the object covering curtain is stable and reliable.
