Description

Technical Field

[0001] This invention relates to a life jacket, and more particularly to a life jacket with a conspicuous distress signal structure, belonging to the field of life jacket technology. Background Technology

[0002] Life jackets help people float on the water's surface. The principle behind them is buoyancy. According to Archimedes' principle, the buoyant force on an object in a liquid is equal to the weight of the liquid it displaces. Life jackets are usually filled with buoyant materials, such as foam plastic or cork, or they are inflatable. These materials can increase the buoyancy of the human body in the water, making the buoyant force greater than the body's own weight, thus allowing the person to float on the water's surface.

[0003] In the prior art, such as the invention with application number 202310050051.4, a life jacket with a conspicuous distress signal structure is disclosed. In order to solve the problem that it is not conspicuous enough in the sea or large lakes and rivers and is not easy to be found by rescuers, a distress signal stick is set up. When the person falls into the water, it will release a conspicuous smoke. The distress signal smoke is large and conspicuous, which can facilitate rescuers to find the person who has fallen into the water.

[0004] The above-mentioned applications still have shortcomings: Using a distress smoke stick to signal for help has a certain degree of visibility, but its duration is only about 3-5 minutes, which is relatively short. Moreover, it is ineffective at night and has low practicality. To address this issue, a life jacket with a prominent distress signal structure was designed. Summary of the Invention

[0005] The main objective of this invention is to provide a life jacket with a conspicuous distress signal structure to solve the problems mentioned in the background art.

[0006] The objective of this invention can be achieved by adopting the following technical solution: A life jacket with a conspicuous distress signal structure includes a life jacket body, a hydrogen tank located on the chest of the life jacket body, a switch valve located at the bottom of the hydrogen tank, an air duct installed at the vent on the side of the switch valve, an inflation bladder installed at the end of the air duct, a release rope wound around the adjustment knob on the switch valve, a cover located below the chest of the life jacket body, and Velcro fasteners on both the cover and the life jacket body. The cover is attached to the surface of the life jacket body, and the hydrogen tank, switch valve, air duct, and inflation bladder are all covered by the cover. The end of the release rope is fixedly connected to the inside of the cover.

[0007] Preferably, a safety rope is provided at the top of the outer side of the cover, and the safety rope is made of nylon.

[0008] Preferably, a fluorescent coating is provided at the middle position of the outer side of the airbag, and distress signs are provided at the top and bottom of the outer side of the airbag.

[0009] Preferably, the top of the airbag is provided with a transparent bladder, the interior of which is connected to the airbag, and the interior of the transparent bladder is provided with a vibration lamp.

[0010] Preferably, a whistle is provided on the side of the life jacket body away from the cover on the chest, and a hanging rope is provided between the top of the whistle and the life jacket body.

[0011] Preferably, waist belts are evenly installed on both sides of the life jacket body, and buckles are provided between the waist belts on both sides of the life jacket body. Limiting straps are symmetrically provided on both sides of the life jacket body, and the waist belts pass through the limiting straps.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The rescue mechanism, consisting of a hydrogen tank, a switch valve, a gas delivery tube, and an inflatable bladder, allows the hydrogen tank to open when the person falls into the water. This inflates the red bladder, making it float in the air for rescuers to see. It is more visible during the day and can be used at night. The transparent bladder at the top of the bladder has a vibrating light that flashes when the person in distress shakes the bladder, further enhancing visibility for nighttime rescues. In addition, the whistle on the life jacket body can also emit a warning sound. This invention combines sound, light, and color cues, making it more visible and practical.

These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a life jacket with a conspicuous distress signal structure, including a life jacket body 1, a hydrogen tank 2 located on the chest of the life jacket body 1, a switch valve 3 located at the bottom of the hydrogen tank 2, an air duct 4 installed at the exhaust port on the side of the switch valve 3, an inflation bag 5 installed at the end of the air duct 4, a release rope 7 wrapped around the adjustment knob on the switch valve 3, a cover 6 located below the chest of the life jacket body 1, and Velcro 10 provided on both the cover 6 and the life jacket body 1. The cover 6 is adhered to the surface of the life jacket body 1, and the hydrogen tank 2, switch valve 3, air duct 4 and inflation bag 5 are all covered by the cover 6. The end of the release rope 7 is fixedly connected to the inside of the cover 6.

[0021] When wearing the life jacket body 1 and falling into the water, the hydrogen tank 2, switch valve 3, air duct 4, and inflatable bladder 5 are initially covered by the cover 6 and are in a stowed state. When a distress call is needed, the cover 6 is pulled down. As the cover 6 is pulled open, the release rope 7 is pulled, which in turn controls the knob on the switch valve 3 to turn, opening the hydrogen tank 2. Compressed hydrogen will enter the interior of the inflatable bladder 5, causing it to inflate. Because hydrogen is relatively light, the inflatable bladder 5 will float in the air, and the red inflatable bladder 5 is more conspicuous, making it easier for rescuers to observe. Example

[0022] The solution in Example 1 will be further described below with reference to its specific working method. like Figure 2 As shown, in a preferred embodiment, based on the above method, a safety rope 601 is further provided on the top of the outer side of the cover 6, and the safety rope 601 is made of nylon. When opening the cover 6, the cover 6 can be opened by simply pinching the safety rope 601 with one hand and pulling it down, which is more convenient to use.

[0023] like Figure 3 As shown, in a preferred embodiment, based on the above method, a fluorescent coating 501 is further provided at the middle position of the outer side of the airbag 5, and distress signs are provided at the top and bottom of the outer side of the airbag 5. The distress signs are more conspicuous during the day and more conspicuous at night thanks to the fluorescent coating 501.

[0024] like Figure 3 As shown, in a preferred embodiment, based on the above method, the top of the airbag 5 is provided with a transparent bladder 502, the interior of the transparent bladder 502 is connected to the airbag 5, and the interior of the transparent bladder 502 is provided with a vibration lamp 503.

[0025] When the inflatable bladder 5 floats in the air, the transparent bladder 502 is located on top of the inflatable bladder 5. When calling for help at night, the inflatable bladder 5 can be pulled through the air tube 4. The vibration light 503 will automatically flash when it is vibrated, which will increase the warning effect. The vibration light 503 is existing technology and is often used in children's toys. Therefore, this application will not elaborate on its working principle.

[0026] like Figure 1 As shown, in a preferred embodiment, based on the above method, a whistle 9 is provided on the side of the life jacket body 1 away from the cover 6 on the chest, and a hanging rope 901 is provided between the top of the whistle 9 and the life jacket body 1. In the process of calling for help, the whistle 9 can also be blown to alert the rescuer.

[0027] like Figure 1As shown, in a preferred embodiment, based on the above method, the life jacket body 1 is further provided with waist belts 8 evenly installed on both sides, and a buckle 801 is provided between the waist belts 8 on both sides of the life jacket body 1. The life jacket body 1 is provided with limiting straps 802 symmetrically on both sides, and the waist belts 8 pass through the limiting straps 802. During the wearing of the life jacket body 1, the waist belts 8 are tightened to prevent the life jacket body 1 from falling off when falling into the water. Example

[0028] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. During the donning of the life jacket body 1, the waist belt 8 is tightened and its two ends are secured with buckles 801. The limiting strap 802 prevents the waist belt 8 from slipping, thus improving the stability of the donning process and preventing the life jacket body 1 from falling off during drowning. Initially, when the life jacket body 1 is donned and the person falls into the water, the hydrogen tank 2, valve 3, air duct 4, and inflation bag 5 are concealed by the cover 6 and are in a retracted state. When a distress call is needed, the cover 6 is pulled down and opened. During the process, the release rope 7 will be pulled, which will control the knob on the switch valve 3 to turn, opening the hydrogen tank 2. Compressed hydrogen will enter the interior of the inflatable bladder 5, causing it to expand. Because hydrogen is relatively light, the inflatable bladder 5 will float in the air, and the red inflatable bladder 5 will be more conspicuous, making it easier for rescuers to observe. When calling for help at night, the inflatable bladder 5 can be pulled through the air tube 4, and the vibration light 503 will automatically flash upon vibration, increasing the alert effect. Alternatively, the whistle 9 can be blown to alert the rescuer.

[0029] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
