Abstract

The invention belongs to the technical field of trampolines (A63B5/11) and discloses a modified structure of a trampoline. The modified structure comprises an upper framework, a lower framework and a piece of elastic cloth. The elastic cloth is arranged on the upper framework; a plurality of inclined flexible rods are placed between the upper framework and the lower framework; a plurality of abutting blocks are arranged on the peripheries of two ends of the flexible rods at equal intervals; a round hole is formed in the end surface of each abutting block; a clamping column is connected in the round hole via a spring; connection channels are formed in relative surfaces of the upper framework and the lower framework; a rabbet of each connection channel is provided with a notch matching with the abutting block; a groove cavity of each connection groove is round; a clamping hole matching with a clamping column is formed in the bottom of the groove cavity; and the clamping hole is staggered with the notch. Compared with a traditional structure relying on bolts or other connection members, installation time can be reduced and quick installation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of A63B5 / 11: trampoline. Background technique [0002] Trampoline is a competitive sport in which athletes perform acrobatic skills by bouncing off the trampoline. It is a kind of gymnastics. The trampoline is known as "air ballet". The history of trampolines can be traced back to the Comanche Indians in North America in the mid-19th century, and acrobats in Chinese circuses have used similar trampolines for at least 200 years. [0003] The pioneer of the modern elastic trampoline is the French acrobat Du Trampolin. He weaves a protective net with hemp rope to enhance the safety of the "air swing trapeze", and uses the elasticity of the net to throw the actor into the air to complete various kind of action. Since the development of trampoline, it has gradually evolved from a sport requiring professional skills to a less difficult recreational sport. Many improved trampolines have entered major playgrounds,...
