Description

Technical Field

[0001] The utility model relates to the technical field of life buoys, in particular to a life buoy for water lifesaving. Background Art

[0002] A life buoy is a type of water life-saving equipment, usually made of cork, foam plastic or other lightweight materials with a low specific gravity, wrapped in canvas, plastic, etc. The life buoy used for swimming practice can also be made of rubber and filled with air, also called a rubber ring;

[0003] Lifebuoys can be divided into round lifebuoys and U-shaped lifebuoys according to their structure. Round lifebuoys are the most common. When in use, the person who falls into the water needs to pass through the middle of the lifebuoy, put his arms on the lifebuoy, and then float on the water surface relying on the buoyancy of the lifebuoy. The person who falls into the water can only rely on the outside of the lifebuoy if he cannot swim. The U-shaped lifebuoy is carried on the neck of the person who falls into the water for use.

[0004] However, the existing life buoy has a simple structure and can only be used by one or two people. When using the life buoy, the person who falls into the water needs to rely on his or her own physical strength to cling to the life buoy. Once the person who falls into the water is physically exhausted, there is a risk of slipping off the life buoy and falling into the water again. Therefore, it does not meet the existing needs. In this regard, we propose a life buoy for water rescue. Utility Model Content

[0007] Preferably, both ends of the upper surface of the auxiliary lifebuoy for fixing personnel are provided with underarm fixing grooves, and the middle of the upper surface of the auxiliary lifebuoy for fixing personnel is provided with a neck clamping groove.

[0008] Preferably, the depth of the underarm fixing groove and the neck back clamping groove is half the thickness of the auxiliary lifebuoy for fixing personnel, and the width of the neck back clamping groove is two to three times the width of the underarm fixing groove.

[0009] Preferably, two upper-shoulder limiting blocks are installed on the inner side of the underarm fixing groove, and the upper-shoulder limiting blocks are bonded and fixed to the inner wall of the underarm fixing groove by adhesive.

[0010] Preferably, the limit block above the shoulder is made of rubber and is hollow inside and filled with compressed gas.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the central lifebuoy of the utility model is squeezed on the water surface by force, since there is air between the pressure buffer groove and the water surface, the downward pressure of the central lifebuoy causes the two sides of the pressure buffer groove to expand laterally, so that the contact area between the bottom of the central lifebuoy and the water surface is increased, thereby changing the buoyancy of the central lifebuoy, ensuring that the load-bearing capacity of the central lifebuoy is increased, and a personnel fixing auxiliary lifebuoy is added to the central lifebuoy, and the personnel fixing auxiliary lifebuoy provides support from under the body of the person who falls into the water, so as to prevent the person who falls into the water from sliding off the central lifebuoy due to physical exhaustion;

[0013] 2. The utility model provides an assembly slot on the surface of the central lifebuoy, and the inner side of the assembly slot is connected with a personnel fixing auxiliary lifebuoy. The personnel fixing auxiliary lifebuoy is passed through the armpits of the user, so that when the user floats on the water surface by relying on the central lifebuoy, the personnel fixing auxiliary lifebuoy with a protective support function under the body can prevent the user from being separated from the central lifebuoy due to body weakness caused by being immersed in water for a long time. In addition, when there are many people falling into the water, the personnel fixing auxiliary lifebuoy is removed from the central lifebuoy, so that one lifebuoy can be used by multiple people to rescue more people falling into the water.

[0014] 2. The utility model provides underarm fixing grooves and neck-back clamping grooves on the surface of the auxiliary lifebuoy for fixing personnel. The user passes the auxiliary lifebuoy for fixing personnel from behind and ensures that the end of the auxiliary lifebuoy for fixing personnel passes through the armpit, then clamps the shoulder in the underarm fixing groove, and clamps the neck in the neck-back clamping groove. The auxiliary lifebuoy for fixing personnel provides buoyancy so that the user's neck and above float on the water surface, and the auxiliary lifebuoy for fixing personnel will not be easily separated from the human body.
