<p>A rotating connecting device and a foldable tent frame are disclosed. The rotating connecting device comprises a main seat (10) fixedly provided with a fixing seat (20), and the fixing seat (20) is provided with a pin-jointed structure for pivoting a rod. The main seat is fixedly provided with a rotating seat (11), the rotating seat is pivoted with a pivot seat (30), and the pivot seat is provided with another pin-jointed structure for pivoting the rod. As the main seat (10) is provided with the rotating seat (11), and the pivot seat (30) is pin-jointed with the rotating seat (11), and the rotating seat (11) and the fixing seat (20) can move relative to each other, therefore the invention has the following technical effects: a, the foldable frames of different length-width ratios can share a common connecting device, thus the mold opening cost is reduced and the foldable frames are convenient to be assembled; and b, the angle changes generated among the rods during the unfolding or folding process of the foldable frames can be adapted automatically.</p> |
