DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, an inflatable lifebuoy device includes a first inflatable part 1 and a second inflatable part 2, the first inflatable part 1 and the second inflatable part 2 are connected by an air pipeline 3, and also includes a three-way valve 4 and an air storage device 5, the three-way valve 4 is connected to the second inflatable part 2, and the air storage device 5 is connected to the three-way valve 4, the first inflatable part 1 has two ends, and the outer surfaces of the two ends of the first inflatable part 1 are respectively installed with front rings 6, and the outer surface of the air pipeline 3 is provided with a rear ring 7, the two front rings 6 are connected by a pull rope 8, and a net 9 is provided between the rear ring 7 and the pull rope 8.

[0017] The first inflatable part 1 is U-shaped, and the second inflatable part 2 is located on one side of the first inflatable part 1. When a person who falls into the water uses the lifebuoy device, the first inflatable part 1 mainly provides buoyancy support for the body of the person who falls into the water through the cooperation of the pull rope 8 and the bag net 9, and the second inflatable part 2 mainly supports the head of the person who falls into the water, so that the head of the person who falls into the water can be better away from the water surface to prevent water from entering the ear canal.

[0018] The gas storage device 5 stores compressed gas. When in use, turn on the control button of the gas storage device 5, and the compressed gas in the gas storage device 5 is quantitatively transported to the first inflatable part 1 and the second inflatable part 2 through the three-way valve 4. After the first inflatable part 1 and the second inflatable part 2 are inflated, they can provide buoyancy support for people who fall into the water. When the lifebuoy device is stored, the air in the first inflatable part 1 and the second inflatable part 2 can be discharged through the three-way valve 4. Since the gas storage device 5 and the three-way valve 4 are both existing technologies, they are not elaborated here.

[0019] The person who falls into the water can effectively grab the lifebuoy device through the net 9 and the pull rope 8. During subsequent use, the first inflatable part 1 is first moved to the back of the person who falls into the water, and then the two ends of the pull rope 8 are grabbed with both hands and the pull rope 8 is pressed downward, so that the buttocks of the person who falls into the water can enter the net 9 of the first inflatable part 1. At the same time, the joints of the calves and thighs of the person who falls into the water are placed on the pull rope 8. The pull rope 8 is positioned relatively high, so that the weight of the person who falls into the water is concentrated on the buttocks, so that the calves and head of the person who falls into the water can be tilted upward, which is convenient for the head of the person who falls into the water to leave the water surface. In addition, due to the low center of gravity, the device can be effectively prevented from tipping over.

[0020] The pull rope 8 can also play a blocking role to prevent people who fall into the water from slipping out of the net 9 of the first inflatable part 1.

[0021] Furthermore, a receiving groove 10 is provided on the outer surface of one end of the second inflatable part 2, and a flip cover 11 is provided on the receiving groove 10. The receiving groove 10 and the flip cover 11 are connected by a zipper. When the device is used, the positions of the receiving groove 10 and the flip cover 11 are as follows: Figure 2 As shown, when the device is stored, the gas in the first inflatable part 1 and the second inflatable part 2 is first emptied, and then the first inflatable part 1 and the second inflatable part 2 are rolled up. After the first inflatable part 1 and the second inflatable part 2 are rolled up, the receiving groove 10 is turned inside out, and the inside of the receiving groove 10 becomes the outside, and the outside becomes the inside. After the receiving groove 10 is turned inside out, it can be used to accommodate the first inflatable part 1, the second inflatable part 2 and other components. Then, the receiving groove 10 is closed by the flip cover 11, and the flip cover 11 is connected to the receiving groove 10 by a zipper, thereby improving the portability of the device.

[0022] Furthermore, anti-skid grooves 12 are arranged at intervals on the upper surface of the second inflatable part 2. The anti-skid grooves 12 are arranged parallel to the pull rope 8. The anti-skid grooves 12 facilitate the stability of the second inflatable part 2 when supporting the head. At the same time, the anti-skid grooves 12 can discharge the water flow entering the second inflatable part 2, thereby reducing the impact on the person's head.

[0023] Furthermore, three gas pipelines 3 are provided, and two gas pipelines 3 located on the outer sides are respectively provided with rear rings 7. Through multiple gas pipelines 3, the speed of gas entering the first inflation part 1 can be increased, and the connection strength between the first inflation part 1 and the second inflation part 2 can also be increased. By providing two rear rings 7, the net 9 can be effectively opened, so as to more safely and stably hold the buttocks of the person who falls into the water, thereby reducing the probability of the buttocks of the person who falls into the water entering the side of the net 9.

[0024] Furthermore, pull rings 13 are respectively provided at both ends of the first inflatable part 1, and the pull rings 13 facilitate personnel on board or on shore to drag the device to move by using a rescue rope.

[0025] The device can facilitate the person who falls into the water to stably grasp the lifebuoy through the pull rope 8 and the bag net 9, and through the pull rope 8 and the bag net 9, the person who falls into the water only needs to sit on the bag net 9, and does not need to spend any effort to stay stable in the water, which is convenient for dealing with rescue situations that require a long wait.
