Abstract
The utility model discloses a folding structure of table leg, comprising a vacuum forming table and a table rack which is buried in the vacuum forming table. A supporting board fixedly connected with the table rack is fixed with a convex lock ear. The both ends of a rocking slide bar with a conical shape are separately provided with a through hole, and the through hole on the big end is rotatablely connected with the lock ear through a rolling pin and sliding sheathed with the table leg of the rocking slide bar. One first end part penetrates into the drive rod of the table leg, and the first end part is fixed with an eccentric pin which is inserted in the through hole on the small end of the rocking slide bar. When the drive rod turns to lock tightly, the eccentric pin rotates towards the direction away from the upper end part of the table leg, and the rocking slide bar slides towards the interior of the table leg; when the table leg tightly leans on the supporting board, the table leg can not rotate; when the drive rod turns to loose, the eccentric pin rotates towards the direction of the upper end part of the table leg, the rocking slide bar slides outwards the table leg to push out the table leg far away from the supporting board, and then the table leg can rotate freely, realizing the opening and folding.
