Abstract: A combined double buckle and bungee cord connecting structure for a trampoline is provided. The combined double buckle and bungee cord connecting structure for a trampoline includes a trampoline frame; an edge-folded round steel connected to an inner side of the trampoline frame; anti-friction bearings connected to the edge-folded round steel equidistantly and rotatably; and bungee cords. The trampoline frame is one of a round shape, a hexagonal shape, and a square shape. The edge-folded round steel is connected to the inner side of the trampoline frame by either welding or riveting. The anti-friction bearings are made of one of a plastic, a metal, and a chemical fiber. The bungee cords each are either a round bungee cord or a flat bungee cord. Therefore, the structure effectively reduces the abrasion of the bungee cords in use and can greatly prolong the service lives of the bungee cords.
