Problems solved by technology

But its shortcoming is that the buoyancy of this two-piece design of the chest and back is similar. When a person falls into the water, he will not automatically turn his body and keep his face upward, which will cause breathing difficulties to rescuers who are not suitable for water; Combustible high-density polyethylene foam material, if its foam sinks in the water for too long, its buoyancy will decrease, which will further consume the rescuer's physical strength, so its structure and material properties need to be improved

Embodiment 1

[0021] Example one, as Figure 1 to Figure 4 As shown, the life jacket of this embodiment includes an outer jacket 1 and an inner core 2 that functions as a float. The outer jacket 1 is in the shape of a core back, and the outer core-back jacket 1 is a cardigan or a pullover. The inner core 2 is placed in the interlayer of the outer jacket 1. The inner core 2 is made of NBR / PVC mixed-molded foam material with a soft feel and a density of 0.034g / cm3. The thickness of the inner core 2 in the outer jacket is at least doubled, the NBR refers to nitrile rubber, and the PVC refers to polyvinyl chloride. The upper outer cover is a knitted fabric or a woven fabric, the knitted fabric is an elastic silk fabric, and its surface is two layers, and a layer of SBR material with a thickness of 1mm is sandwiched between the two layers, and the inner fabric is a layer, the surface is covered with a layer of SBR material with a thickness of 1mm. The woven fabric is a polyester fabric, the ou...

Abstract

The invention relates to a life jacket which comprises an overcoat (1) and an inner core (2) with the floater effect. The inner core (2) is arranged in the interlayer of the overcoat (1); the inner core (2) is made of foam material formed by mixing and pressing NBR / PVC with soft hand feel and the density being of 0.034g / cm; and the thickness of the part, which is arranged in the overcoat at the chest, of the inner core (2) is at least two times as that of the part, which is arranged in the overcoat at the back, of the inner core (2). The life jacket has the advantages that because the thickness of the part, which is arranged in the overcoat at the chest, of the inner core is at least two times as that of the part, which is arranged in the overcoat at the back, of the inner core, and the buoyancy of the inner core at the chest is large, when falling into the water, a user can automatically turnover the body to keep face upward, the life safety of the user who can not swim can be effectively ensured, the use is safe, and the effect is better; furthermore, the material of the inner core feels soft, the inner core not only has good fitting when being worn, but also is convenient for the user to stoop down, squat down or do various motions, moreover, because the density of the inner core is only 0.034 g / cm, and the weight of each produced life jacket is less than or equal to 0.8 kg, so that the life jacket is light and convenient to carry.

Description

technical field [0001] The present invention relates to a life jacket, which is used for fishing in the sea, river and lake, taking pleasure in yachts, etc., or when carrying out marine engineering operations, and for floating the user's body when a water disaster occurs. Background technique [0002] The existing Chinese utility model patent with the patent number CN93214217.6 and the name "Super Buoyancy Life Jacket" discloses a structure, the structure adopts a novel waterproof and flame retardant fabric to form the inner and outer layers of the "life jacket", The liner between the inner and outer layers has a specially treated non-absorbent, flame-retardant high-density polyethylene foam material interlayer, sewn into a specific form of chest and back two pieces, made of flashing tape, equipped with sub-shaped buckle clips. Nylon high-strength webbing is stitched together. It is safe and reliable, has super buoyancy and warmth retention functions, and has the advantages...
