[0056] Exemplarily, the front sides of the two shoulder strap rings 1 are respectively provided with chest reflective strips 10.

[0057] Exemplarily, the rear side of each of the two shoulder strap rings 1 is provided with a back reflective strip 16.

[0058] The provision of the shoulder reflective strip 9, the chest reflective strip 10 and the back reflective strip 16 can improve the visibility of the wearer.

[0059] Exemplarily, a cow tail rope 11 is further provided on the shoulder strap ring 1. Specifically, the cow tail rope 11 is provided on the rear side of the shoulder strap ring 1. The cow tail rope 11 serves as a quick release device and can be used for escape in case of emergency in water.

[0060] Exemplarily, a mesh bag 14 is further provided on the front side of the shoulder strap ring 1. The mesh bag 14 can hold auxiliary rescue equipment such as a life buoy whistle, a sound and light alarm device, etc.

[0061] The implementation process is as follows:

[0062] When the wearer wearing the amphibious rescue harness moves on land, the harness does not need to be inflated, which can ensure the normal movement of the wearer. The rescue rope can be connected through the chest and back rings, which can play a protective role when climbing and climbing, and complete activities such as climbing and climbing.

[0063] When the wearer moves in water, the harness can generate a certain buoyancy through the foam plastic in the upper body inflation part in the un-inflated state, so that the wearer floats on the water. When the wearer needs to rescue a person falling into the water or carry rescue equipment, the rope of the compressed bottle can be pulled to release the gas in the compressed bottle to inflate the harness to provide additional buoyancy. When the gas in the compressed bottle is insufficient or the buoyancy is insufficient, the wearer can also inflate the harness to provide buoyancy through the inflation nozzle. A one-way valve is provided at the connection between the inflation nozzle and the harness, so that the gas in the harness will not escape from the nozzle. When the wearer is stuck by the rope in the water, the wearer can quickly escape from danger by untying the cow tail rope. The wearer can call for help through the life buoy whistle, sound and light alarm device, etc. in the mesh bag.

[0064] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model. The ordinary skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
