Abstract
A foldable tent center lock device with a rotary unlocking structure, which includes a center telescopic rod. The center telescopic rod includes an outer tube and an inner tube. An upper end of the outer tube is fixedly provided with a top disc. A lower end of the inner tube is fixedly provided with a bottom disc assembly. The bottom disc assembly includes a bottom disc body, a rotating disc cooperating rotatably with the bottom disc body, and a locking member mounted cooperatively between the bottom disc body and the rotating disc and used for being in locking cooperation with the outer tube. The center telescopic rod can be retracted so that the foldable tent inner center lock is locked and a foldable tent is expanded. When the rotary disc rotates, the rotating disc unlocks the locking member, so that the center telescopic rod extends to fold the foldable tent.
