Problems solved by technology

[0002] In view of the fact that the traditional water lifesaving equipment (including life jackets, swimming rings, and various flotation devices) currently used in ships, airplanes, docks, swimming pools and other means of transportation and public areas is heavy, bulky, difficult to store and carry, and inconvenient to wear around, uncomfortable
Therefore, whether it is a tourist who cannot swim or a swimmer who can swim, when a drowning accident actually occurs, they often do not wear traditional water lifesaving equipment, or it is too late to wear it, causing life-threatening

Embodiment 1

[0018] Such as figure 1 and image 3 Shown is a wrist (arm) belt for self-rescue in water. The wrist (arm) belt 1 is worn on the wrist or arm after the length is adjusted by the length adjustment buckle 6, and the chemical inflatable bag 3 is fixed by a special fixing bolt 2. When needed, any switch lead wire 4 is pulled, and the switch lead wires are connected in parallel with the buckle 5 so that the switch lead wires 4 of all chemical inflatable bags 3 are pulled out, and the gas-producing substances inside the chemical inflatable bag 3 are mixed to produce a large amount of gas rapidly, and the self-rescue wrist (arm ) with 1 becomes a life buoy.

Embodiment 2

[0020] Such as figure 2 The chemical inflatable bag 3 fixed on the self-rescue wrist (arm) belt 1 shown, the inside of the chemical inflatable bag 3 is composed of a heat insulation layer 12, a chemical filler layer 8, a catalyst layer 7, a catalyst layer wrapped film 11, a water-stop Air-permeable layer 10, rubber inflatable layer 9, fixed buckle 2 and inflatable switch lead wire 4, the chemical filler layer 8 is filled with solid hydrogen peroxide compound and / or pure substance or mixture of solid peroxide, so The catalyst layer 7 is filled with special solid metal oxide and a small amount of water, or FeCl3 solution, the gas charging switch lead wire 4 is embedded in the catalyst layer wrapping film 11, when the gas charging switch lead wire 4 is pulled out, the catalyst layer The outer film 11 is broken, and the catalyst layer 7 is filled with a special solid metal oxide and a small amount of water, which is in contact with the chemical filler layer 8, which is filled wit...

Abstract

The invention relates to an underwater self-rescue wrist (arm) belt carried with a user. The underwater self-rescue wrist (arm) belt carried with the user is characterized by comprising a length-adjustable wrist (arm) belt body and one or more chemical inflatable bags which are fixed to the length-adjustable wrist (arm) belt body. The underwater self-rescue wrist (arm) belt carried with the user can be worn on the wrist or the arm or other parts of a body, the chemical inflatable bag becomes a small swim ring in several seconds simply by pulling an inflating switch lead when the user is in the danger of drowning or the danger of drowning is foreseen, and thus the danger of drowning is avoided.

Description

technical field [0001] The invention relates to an underwater self-rescue device, in particular to an underwater self-rescue wrist (arm) belt worn by people. Background technique [0002] In view of the fact that the traditional water lifesaving equipment (including life jackets, swimming rings, and various flotation devices) currently used in ships, airplanes, docks, swimming pools and other means of transportation and public areas is heavy, bulky, difficult to store and carry, and inconvenient to wear around, uncomfortable. Therefore, whether it is a tourist who cannot swim or a swimmer who can swim, when an actual drowning accident occurs, they often do not wear traditional water lifesaving equipment, or it is too late to wear it, causing life-threatening. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a portable underwater self-rescue wrist (arm) belt, which can be easily worn on the wrist, ar...
