Abstract
A top setting-up mechanism for folding tent includes an upper hub pivotally connected to inner ends of upper ribs of the tent, a lower hub pivotally connected to inner ends of stretchers of the tent, and a pull cord. A guiding tube having internal guiding ribs is fitted in the upper hub. An upper part of the lower hub is formed into a hollow retainer having external guiding grooves. When the pull cord is pulled, the retainer on the lower hub is brought into the guiding tube to enable quick and accurate coupling of the lower hub to the upper hub, and the guiding grooves on the retainer of the lower hub interfere with the guiding ribs on the guiding tube fitted in the upper hub to prevent the upper and the lower hub from turning relative to one another, and thereby ensures a stable erection of the tent.
