Problems solved by technology

The trampoline in the prior art has the following defects: 1. The frame volume of the trampoline is relatively large, so when the manufacturer produces the trampoline product, each assembled trampoline will have a considerable volume, and not only the finished product will be stored in the factory. It will occupy the limited space in the factory, and it will increase the transportation cost when it is exported. Moreover, regardless of the store for exhibition or individual users, the trampoline will occupy a considerable indoor space when it is not in use.
However, this kind of protective pad needs to increase the cost of the trampoline; increase the assembly time, and at the same time, due to the elastic deformation of the spring, the protective pad is tightly covered when not in use, but after the elastic deformation of the spring, the protective pad deviates, resulting in coverage The spring is exposed due to unevenness, which may increase the incidence of safety accidents
3. Because the spring is used as the elastic part and the protective pad is used to cover the laying, the effective use area of ​​the trampoline is greatly reduced, and the existence of the spring limits the actual jumping space of the trampoline
In the prior art, elastic cloth is used to replace the spring, but there are problems such as short service life of elastic cloth and poor elasticity uniformity of the cloth surface.

Abstract

The invention relates to elastic composite cloth. The elastic composite cloth is characterized in that the elastic composite cloth is of a double-layer structure, one layer of the elastic composite cloth is an elastic-material band made of nylon fibers, the other layer of the elastic composite cloth is a material band made of cellulose fibers, and the two layers are combined through a high-molecular elastic layer.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2016106277820, the invention name is a durable elastic composite material, and the application date is 20160803. technical field [0002] The invention belongs to the field of elastic composite materials. Background technique [0003] In 2009, "Bedjump" quickly became popular on the website, translated into Chinese as "trampoline" or "jumping bed". There are many fans who love this sport all over the world. Enthusiasts usually choose a springy bed, jump up, and make various movements in the air. The trampoline is mainly provided with a fabric tensed by a plurality of springs in the frame supported by the foot stand, for the user to stand on the bouncing surface and continuously bounce for interesting sports. The trampoline in the prior art has the following defects: 1. The frame volume of the trampoline is relatively large, so when the manufacturer produces...
