MULTIPLE-LAYER STRUCTURE OF INFLATABLE DEVICE CAPABLE OF PRESSURE RESISTANCE

摘要

A multiple-layer structure of inflatable device (100) capable of pressure resistance includes a gasbag unit (1) and a reinforcing shape-forming net (2). The gasbag unit (1) includes a gas inlet (11), a flexible waterproof inner tube (12) for fluid communication with the gas inlet (11), and a flexible material of outer tube (14) covering the flexible waterproof inner tube (12), wherein the gasbag unit (1) and the reinforcing shape-forming net (2) covering the gasbag unit (1) are both in independent structures. When the gasbag unit (1) becomes expanded over the reinforcing shape-forming net (2), the reinforcing shape-forming net (2) will resist the applied force from the gasbag unit (1), so that the gasbag unit can be made of light weight material and thus the maintenance and renew become easy. The present invention is not only easy in maintenance but also efficiently reducing cost for all kinds of inflatable products and environment protection.
