Outdoor waterproof knapsack with life buoy function and using method thereof

Abstract

The invention discloses an outdoor waterproof knapsack with a life buoy function and a using method of the outdoor waterproof knapsack. The knapsack comprises a cylindrical knapsack main body which isformed by hot-pressing and fitting the waterproof cloths into a cylindrical shape through a hot melt adhesive and is provided with an opening at the upper part, a sealing belt which is fixed to the opening at the upper part of the knapsack main body in a sewing manner, connecting buckles which are arranged at the two ends of the sealing belt, straps which are arranged at the back of the knapsackmain body, and hand straps which are arranged at the upper ends of the straps. The straps and the hand straps are fixed to a sixth cloth block in a sewing manner, and the sixth cloth block is hot-pressed and fitted to the back face of the knapsack main body through the hot melt adhesive. According to the invention, the knapsack main body is formed into a sealed cylindrical structure with the upperopening by hot-pressing and fitting the waterproof cloths together through the hot melt adhesive, and other components are indirectly installed on the knapsack main body through the cloth blocks in ahot melt adhesive hot-pressing attaching manner, so that the knapsack main body has good waterproof performance, and the knapsack main body can be used as a life buoy after a person is drowned so asto strive for the precious rescue time for the drowner because of the good air tightness of the knapsack main body.

Description

Technical field: [0001] The invention relates to the field of backpacks, in particular to an outdoor waterproof backpack with the function of a life buoy and a use method thereof. Background technique: [0002] Backpack refers to the collective name of the bag carried on the back when going out or marching. It is usually made of polyester, canvas, nylon, cotton and linen and other materials. [0003] At present, the outdoor backpacks on the market are usually only water-proof on the surface, so that water droplets cannot gather and penetrate into the backpack. The specific waterproof structure is usually sprayed with a layer of anti-water film on the surface of the backpack after processing, because the airtightness of the waterproof film is not enough. , and after a period of use, the exposed waterproof membrane is prone to aging and cracking, resulting in poor waterproof performance. [0004] In view of this, the inventor proposes the following technical solutions. Inve...
