Abstract
A collapsible stroller frame capable of being either collapsed or expanded with a rod set, wherein a slide sleeve is located at a front supporter of the stroller frame and a foldable supporter is pivotally connected between the front supporter and a rear supporter. A link rod connects the slide sleeve and the foldable supporter, and is pivotally connected between the front and rear supporter. The foldable supporter includes a front folding tube and a rear folding tube, pivotally connected to each other. A user can operate the foldable supporter to shorten the distance between the front and rear folding tubes, by disengaging the slide sleeve from the frame, thereby facilitating assembly and folding of the stroller.
