Patent ID: 10799743

Abstract:
A trampoline includes a plurality of arc-shaped rods and a plurality of long iron joints. The long iron joints are T-shaped. The arc-shaped rods and the long iron joints are insertedly connected to each other successively and alternatively to form a circular ring. Lower ends of the long iron joints are insertedly connected to straight tubes. Lower ends of two adjacent straight tubes are insertedly connected to a foot tube. The foot tube is U-shaped with an opening upward. The arc-shaped rods are connected to a fabric clamp through arc-shaped hook springs. The fabric clamp inner end is connected to an edge of the trampoline fabric. Grooves are insertedly connected in the inward protrusions, preventing the arc-shaped rods from rotating relative to the horizontal tube. The fabric clamp outer sheet closes the interval between the tension spring and the trampoline fabric, preventing users from stepping into the interval.
