Abstract
Description
Technical Field
[0001] This invention relates to the field of lifesaving device technology, and more specifically, to a portable automatic inflation lifesaving device. Background Technology
[0002] An inflatable lifesaving device is a water rescue apparatus that provides buoyancy through inflation. Its main purpose is to provide temporary floating support in the water, helping a person who has fallen into the water keep their head above water, thereby extending their survival time while awaiting rescue. The primary reason for using inflatable lifesaving devices is that during water activities, if an accident such as drowning occurs, rescuers may not be able to reach the scene immediately. In such situations, inflatable lifesaving devices can provide temporary floating support, buying the user more time to survive.
[0003] Currently, various personal flotation devices and lifebuoys are in use. When someone accidentally falls into the water, at least one person (for example, one or more crew members or rescue team members) may fall into the water with a lifebuoy and try to swim to the person in the water and guide the lifebuoy to the person in the water. However, at least one other person trying to rescue may also face great risks and dangers in the water, which may further aggravate the drowning risk and increase the difficulty of the rescue. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a portable automatic inflation life-saving device, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable automatic inflatable life-saving device, comprising a limiting cylinder for support, wherein an inflatable life-saving component is provided on the limiting cylinder; The inflatable lifesaving assembly includes a reinforced protective cylinder disposed outside the limiting cylinder for protection, and an extension sleeve located outside the limiting cylinder is disposed inside the reinforced protective cylinder. One end of the extension sleeve and located outside the limiting cylinder is provided with an elastic sealing and locking element for sealing, and a limiting ring for limiting is provided on the outside of the limiting cylinder. As can be seen, the above technical solution, by setting the extension sleeve, elastic sealing locking component and limiting ring, can limit the reinforcing protective cylinder when it is installed outside the limiting cylinder, so as to ensure the stability of the installation of the reinforcing protective cylinder; The extension sleeve has a gas generator storage chamber for guiding flow inside. A limiting seat for supporting the gas generator storage chamber is provided outside the gas generator storage chamber and inside the limiting cylinder. The outer side of the limiting seat extends to the limiting cylinder and is detachably connected to the limiting cylinder. One end of the gas generator storage chamber is provided with a reinforced ignition device for limiting position. Inside the reinforced ignition device and at one end of the gas generator storage chamber, a rupture disc is provided. On one side of the reinforced ignition device and inside the limiting cylinder, a guide cylinder for limiting position is provided. A punch extending to one side of the reinforced ignition device is slidably connected inside the guide cylinder. A spring is provided on the outside of the punch at the end of the guide cylinder. The spring is detachably connected to the guide cylinder. A pull plate is provided at one end of the spring away from the guide cylinder, and a pull knob for manual pulling is provided on one side of the pull plate. As can be seen, in the above technical solution, when the pull plate is displaced, it drives the punch to displace and stretches the spring. Then, the pull and torque are released, causing the pull plate, spring and punch to lose their limits. The punch can penetrate the guide tube and hit the enhanced ignition igniter through the traction force when the spring is reset. The enhanced ignition igniter will produce a small-scale explosion and generate an ignition signal, causing the rupture disc to explode violently and generate a large amount of gas, which is then transported to the gas generator storage chamber through the second flow-guiding one-way valve. An elastic rescue airbag ring is provided at one end of the gas generator storage chamber. A first flow-guiding one-way valve is provided on one side of the elastic rescue airbag ring, located at one end of the inner cavity of the gas generator storage chamber. A second flow-guiding one-way valve is provided on one side of the first flow-guiding one-way valve, located inside the gas generator storage chamber, and on the side of the enhanced igniter. A protective sleeve for protection is provided on the outer side of the elastic rescue airbag ring. A limit seat is provided on the outer side of the limit seat, which is installed on the gas generator storage chamber to limit the position of the limit seat. The protective sleeve has a limiting card protective cover at one end and outside the first flow guide barrier check valve for limiting the position. One end of the limiting card protective cover extends to the reinforcing protective cylinder and is detachably connected to the reinforcing protective cylinder. An elastic sleeve is provided on one side of the limiting card protective cover outside the reinforcing protective cylinder. A quick-connect connector is provided on the outside of the quick-connect connector extending to the inner wall of the limiting card protective cover. A protective ring is provided on one side of the quick-connect connector and installed on the gas generator storage chamber for limiting the position of the quick-connect connector. As can be seen, in the above technical solution, when the high-pressure gas is transported in the gas generator storage chamber, the gas is blocked by the second flow-guiding one-way valve to prevent the high-pressure gas flow from flowing back. At the same time, when the gas flow is transported in the gas generator storage chamber, it is injected into the elastic rescue airbag ring through the first flow-guiding one-way valve, causing the elastic rescue airbag ring to expand rapidly and push open the protective sleeve to float on the water surface, improving the convenience of the device during use. When the elastic rescue airbag ring is contracted, the protective sleeve can protect the elastic rescue airbag ring and prevent damage to it. Loosening the elastic rescue airbag ring allows it to deflate and is then pushed back into the protective sleeve. Pulling the reinforcing protective cylinder causes the extension sleeve and elastic sealing locking element to shift, loosening and tightening the gas generator storage chamber and the limiting cylinder, allowing the gas generator storage chamber to be extracted from the limiting cylinder. This allows the reinforced igniter to be disassembled from one end of the gas generator storage chamber and the rupture disc to be replaced, facilitating the reuse of the device. The technical effects and advantages of this invention are as follows: 1. When the pull plate is displaced during use, the spring is stretched and the pull plate, spring and punch are displaced. Then the pull plate is released, so that the pull plate, spring and punch lose their limit. The punch can pass through the guide tube and hit the enhanced igniter by the traction force when the spring returns to its original position, so that the user can operate quickly and improve the convenience of the device during use. 2. This invention enhances the ignition device to generate a small-scale explosion and ignition signal, causing the rupture disc to explode violently and generate a large amount of gas, which is then transported to the gas generator storage chamber through the second flow-guiding one-way valve. When the high-pressure gas is transported in the gas generator storage chamber, the gas is blocked by the second flow-guiding one-way valve to prevent the high-pressure gas flow from flowing back. 3. When the high-pressure gas of the present invention is transported in the gas generator storage chamber, it is injected into the elastic rescue airbag ring through the first flow guide barrier one-way valve, so that the elastic rescue airbag ring expands rapidly and pushes open the protective sleeve to float on the water surface, improving the convenience of the device during use. When the elastic rescue airbag ring is contracted together, the protective sleeve can protect the elastic rescue airbag ring and prevent damage to the elastic rescue airbag ring. 4. The present invention releases the elastic rescue airbag ring and pushes it back into the protective sleeve. Pulling the reinforced protective cylinder causes the extension sleeve and elastic sealing locking element to shift, loosening and tightening the gas generator storage chamber and the limiting cylinder so that the gas generator storage chamber can be pulled out into the limiting cylinder. This allows the reinforced igniter to be disassembled from one end of the gas generator storage chamber and the rupture disc to be replaced, facilitating the reuse of the device. In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of various structures, the punch can penetrate the guide tube and impact the enhanced igniter by the traction force when the spring returns to its original position, facilitating quick operation by the user and improving the convenience of the device during use. The rupture disc violently deflagrates and generates a large amount of gas, which is then transported to the gas generator storage chamber through the second flow-guiding one-way valve. When the high-pressure gas is transported in the gas generator storage chamber, it is blocked by the second flow-guiding one-way valve to prevent backflow of the high-pressure gas flow. When the high-pressure gas is transported in the gas generator storage chamber, it is injected into the elastic rescue airbag ring through the first flow-guiding one-way valve, causing the elastic rescue airbag ring to expand rapidly and push open the protective sleeve to float on the water surface, improving the convenience and safety during rescue. It is convenient to use and has good practicality. Attached Figure Description

[0018] As attached Figure 1-7The portable automatic inflatable life-saving device shown features an inflatable life-saving component on a limiting cylinder 1. The punch 205, through the traction force of the spring 206 during reset, penetrates the guide cylinder 204 and strikes the enhanced igniter 202, facilitating quick operation and improving the device's usability. The rupture disc 203 violently explodes, generating a large amount of gas which is then transported to the gas generator storage chamber 2 via the second flow-blocking one-way valve 302. While the high-pressure gas is being transported within the gas generator storage chamber 2, it is blocked by the second flow-blocking one-way valve 302 to prevent backflow. Simultaneously, the high-pressure gas is injected into the elastic rescue airbag ring 3 via the first flow-blocking one-way valve 301, causing the elastic rescue airbag ring 3 to rapidly inflate and push open the protective sleeve 303, floating on the water surface. This enhances the convenience and safety during rescue operations. The device is convenient to use and highly practical. The specific structural configuration of the component is as follows. The inflatable lifesaving assembly includes a reinforced protective cylinder 101 disposed outside the limiting cylinder 1 for protection, and an extension sleeve 102 located outside the limiting cylinder 1 is disposed inside the reinforced protective cylinder 101. An elastic sealing locking element 103 for sealing is provided at one end of the extension sleeve 102 and on the outside of the limiting cylinder 1, and a limiting ring 104 for limiting is provided on the outside of the limiting cylinder 1. The extension sleeve 102 has a gas generator storage chamber 2 for guiding flow inside. A limiting seat 201 for supporting the gas generator storage chamber 2 is provided outside the gas generator storage chamber 2 and inside the limiting cylinder 1. The outer side of the limiting seat 201 extends to the limiting cylinder 1 and is detachably connected to the limiting cylinder 1. A reinforced igniter 202 for limiting is provided at one end of the gas generator storage chamber 2. A rupture disc 203 is provided inside the reinforced igniter 202 and at one end of the gas generator storage chamber 2. A guide cylinder 204 for limiting is provided on one side of the reinforced igniter 202 and inside the limiting cylinder 1. A punch 205 extending to one side of the reinforced igniter 202 is slidably connected inside the guide cylinder 204. A spring 206 is provided on the outside of the punch 205 at the end of the guide cylinder 204. The spring 206 is detachably connected to the guide cylinder 204. A pull plate 207 is provided at one end of the spring 206 away from the guide cylinder 204, and a pull knob 208 for manual pulling is provided on one side of the pull plate 207. An elastic rescue airbag ring 3 is provided at one end of the gas generator storage chamber 2. A first flow-guiding one-way valve 301 is provided on one side of the elastic rescue airbag ring 3, located at one end of the inner cavity of the gas generator storage chamber 2. A second flow-guiding one-way valve 302 is provided on one side of the first flow-guiding one-way valve 301 and inside the gas generator storage chamber 2, located on one side of the enhanced igniter 202. A protective sleeve 303 is provided on the outer side of the elastic rescue airbag ring 3 for protection. A stop plate 304 is provided on the outer side of the limiting seat 201 for limiting the limiting seat 201 and is installed on the gas generator storage chamber 2. One end of 303 and located outside the first flow-guiding barrier check valve 301 is provided with a limit card protective cover 305 for limiting the position. One end of the limit card protective cover 305 extends to the reinforcing protective cylinder 101 and is detachably connected to the reinforcing protective cylinder 101. One side of the limit card protective cover 305 is provided with an elastic sleeve 306 located outside the reinforcing protective cylinder 101. The quick connector 307 is provided on the outside of the quick connector 307 and extends to the inner wall of the limit card protective cover 305. One side of the quick connector 307 is provided with a protective ring 308 installed on the gas generator storage chamber 2 for limiting the position of the quick connector 307.
[0019] According to the above structure, when an emergency occurs and rescue is needed, pulling the pull knob 208 causes the pull plate 207 to move. When the pull plate 207 moves, it causes the punch 205 to move and the spring 206 to stretch. Then, the pull knob 208 is released, so that the pull plate 207, spring 206 and punch 205 lose their limit. The punch 205 can penetrate the guide tube 204 and hit the enhanced igniter 202 by the traction force when the spring 206 returns to its original position. At this time, the enhanced ignition igniter 202 will produce a small-scale explosion and generate an ignition signal, causing the rupture disc 203 to explode violently and generate a large amount of gas, which is then transported to the gas generator storage chamber 2 through the second flow-guiding one-way valve 302. When high-pressure gas is transported in the gas generator storage chamber 2, the gas is blocked by the second flow-guiding one-way valve 302 to prevent the high-pressure gas flow from flowing back. At the same time, when the gas flow is transported in the gas generator storage chamber 2, it is injected into the elastic rescue airbag ring 3 through the first flow-guiding one-way valve 301, causing the elastic rescue airbag ring 3 to expand rapidly and push open the protective sleeve 303 to float on the water surface, improving the convenience of the device during use. When the elastic rescue airbag ring 3 is contracted, the protective sleeve 303 can protect the elastic rescue airbag ring 3 and prevent the elastic rescue airbag ring 3 from being damaged. Furthermore, during subsequent recovery, the elastic rescue airbag ring 3 is loosened to deflate it, and the elastic rescue airbag ring 3 is pushed back into the protective sleeve 303. The reinforcing protective cylinder 101 is pulled to move the extension sleeve 102 and the elastic sealing locking element 103, thereby loosening and tightening the gas generator storage chamber 2 and the limiting cylinder 1. This allows the gas generator storage chamber 2 to be extracted from the limiting cylinder 1, enabling the enhanced igniter 202 to be disassembled from one end of the gas generator storage chamber 2 and the rupture disc 203 to be replaced, facilitating the reuse of the device. Furthermore, by setting the extension sleeve 102, the elastic sealing locking element 103 and the limiting ring 104, the reinforcing protective cylinder 101 can be limited when it is installed outside the limiting cylinder 1, so as to ensure the stability of the installation of the reinforcing protective cylinder 101. The quick-connect connector 307 and the protective ring 308 can limit the first flow guide barrier check valve 301 after it is installed, so as to ensure the stability of the device during operation.
[0020] Unlike existing technologies, this application discloses a portable automatic inflatable lifesaving device. The punch 205, through the traction force of the spring 206 during its reset, penetrates the guide cylinder 204 and impacts the enhanced igniter 202, facilitating quick operation and improving the device's usability. The rupture disc 203 violently explodes, generating a large amount of gas which is then transported to the gas generator storage chamber 2 via the second flow-blocking one-way valve 302. While the high-pressure gas is being transported within the gas generator storage chamber 2, the second flow-blocking one-way valve 302 blocks the gas flow, preventing backflow. Simultaneously, the high-pressure gas is injected into the elastic rescue airbag ring 3 via the first flow-blocking one-way valve 301, causing the elastic rescue airbag ring 3 to rapidly inflate and push open the protective sleeve 303, floating on the water surface. This enhances the convenience and safety during rescue operations, providing both ease of use and practicality.
[0021] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
