Description

Technical Field

[0001] This invention relates to an inflation valve mechanism, and more particularly to a rapid inflation valve mechanism for a portable life ring. Background Technology

[0002] Portable life rings are foldable water emergency devices that automatically inflate upon contact with water to provide buoyancy. They are suitable for self-rescue and rescue in scenarios such as swimming and flood control. Rapid inflation requires the use of a high-pressure gas cylinder in conjunction with a rapid inflation valve to quickly inflate the life ring.

[0003] Most existing portable lifebuoys use manual or mechanical inflation valves, which require a triggering device to connect to the high-pressure gas cylinder. The triggering mechanism is driven by a pull rope, which directly connects the gas cylinder to the valve for rapid inflation, increasing the overall complexity of the lifebuoy inflation mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid inflation valve mechanism for a portable life ring to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid inflation valve mechanism for a portable lifebuoy, comprising a high-pressure gas cylinder, a lifebuoy, and further comprising: The valve body has a gas cylinder connector fixedly connected to its outer wall, which cooperates with a high-pressure gas cylinder, and a sealing ring fixedly connected to its inner wall. A gasket, wherein a sealing ball head is fixedly connected to the top of the gasket and the sealing ring cooperates with each other, and a telescopic rod is fixedly connected to the bottom of the gasket, and a return spring is sleeved on the telescopic rod; A raised edge is fixedly installed on the outer wall of the valve body. A limiting groove is formed in the raised edge and communicates with the inside of the valve body. A limiting slide rod is slidably installed in the raised edge. The limiting slide rod has an installation groove and a roller is rotatably installed in the installation groove via a shaft. An insurance institution, which is used to restrict the movement of the limit slider.

[0006] Preferably, a support rod is fixedly connected to the inner wall of the valve body and below the sealing ring, the lower end of the telescopic rod is fixedly connected to the support rod, and a sealing gasket is fixedly connected to the outer wall of the valve body.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0021] Example 1: A rapid inflation valve mechanism for a portable life ring, comprising a high-pressure gas cylinder 9, a life ring, and further comprising: Valve body 1, with a gas cylinder connector 101 fixedly connected to the outer wall of valve body 1, the gas cylinder connector 101 cooperating with high-pressure gas cylinder 9, and a sealing ring 102 fixedly connected to the inner wall of valve body 1. Washer ring 5, a sealing ball head 501 is fixedly connected to the top of washer ring 5, the sealing ball head 501 cooperates with the sealing ring 102, a telescopic rod 502 is fixedly connected to the bottom of washer ring 5, and a return spring 503 is sleeved on the telescopic rod 502. A flange 3 is fixedly installed on the outer wall of the valve body 1. A limiting groove 301 is opened in the flange 3. The limiting groove 301 is connected to the inside of the valve body 1. A limiting rod 4 is slidably installed in the flange 3. The limiting rod 4 has an installation groove. A roller 401 is rotatably installed in the installation groove through a shaft. Insurance institutions are used to limit the movement of limit slider 4.

[0022] In this embodiment, the high-pressure gas cylinder 9 can be directly connected to the valve body 1 by the cooperation of the gas cylinder connector 101 and the high-pressure gas cylinder 9. The limiting slide rod 4 is slidably installed inside the limiting slide groove 301. The end of the limiting slide rod 4 is located inside the valve body 1 and below the gasket 5. Thus, the limiting slide rod 4 restricts the backward movement of the gasket 5. The sealing ball head 501 cooperates with the sealing ring 102. The sealing ball head 501 abuts against the sealing ring 102 to block the internal passage of the valve body 1, preventing the gas inside the high-pressure gas cylinder 9 from directly rushing into the life ring through the valve body 1. The safety mechanism restricts the movement of the limiting slide rod 4 to prevent the limiting slide rod 4 from being accidentally pulled during transportation, which would cause the gas inside the high-pressure gas cylinder 9 to push the sealing ball head 501 into the life ring. Before use, the safety mechanism can be released, and the limiting slide rod 4 can be pulled manually. The end of the limiting slide rod 4 is rotatably mounted with a shaft. Roller 401 directly contacts the bottom of the washer 5, avoiding the pressure exerted by external air pressure on the sealing ball head 501. This prevents excessive friction caused by the washer 5 tightly adhering to the outer wall of the limiting slide rod 4, making it difficult to pull the limiting slide rod 4. When the limiting slide rod 4 moves the roller 401 to the side, the lower end of the washer 5 loses support. At this time, the sealing ball head 501 is pushed backward by the high-pressure gas, allowing the gas to be directly injected into the life ring through the valve body 1, achieving rapid inflation of the life ring. After the air pressure between the high-pressure gas cylinder 9 and the life ring is balanced, the return spring 503 pushes the washer 5 upward, and the washer 5 drives the sealing ball head 501 to re-adhere to the edge of the sealing ring 102, resealing the internal passage of the valve body 1 and preventing gas leakage from the valve body 1. At the same time, the safety and triggering mechanisms are integrated, simplifying the rapid inflation mechanism of the portable life ring.

[0023] Example 2: A support rod 103 is fixedly connected to the inner wall of the valve body 1 and below the sealing ring 102. The lower end of the telescopic rod 502 is fixedly connected to the support rod 103. A sealing gasket 2 is fixedly connected to the outer wall of the valve body 1. The lower end of the valve body 1 is inserted into the life ring. The sealing gasket 2 is bonded to the outer wall of the life ring with high-strength adhesive.

[0024] In this embodiment, the telescopic rod 502 is supported by the support rod 103. The telescopic rod 502 is used to restrict the gasket 5 to move up and down only inside the valve body 1. High-strength adhesive is applied to the underside of the sealing gasket 2 to adhere and bond the sealing gasket 2 to the outer wall of the life ring, thereby sealing the gap between the valve body 1 and the life ring and ensuring that the valve body 1 is sealed and installed on the life ring.

[0025] Example 3: The safety mechanism includes a threaded post 303, with a pull ring 305 fixedly connected to one end of the threaded post 303 and a safety pin 304 fixedly connected to the other end of the threaded post 303. A threaded sleeve block 302 is embedded in the outer wall of the protruding edge 3, and the threaded sleeve block 302 is threadedly engaged with the threaded post 303. A connecting rod 402 is fixedly connected to the other end of the limiting slide rod 4. A limiting pin hole 403 is opened in the connecting rod 402, and the limiting pin hole 403 and the safety pin 304 cooperate with each other. A sealing washer 406 is fixedly connected to the end of the limiting slide rod 4 and around the connecting rod 402. A pressing block 404 is fixedly connected to the other end of the connecting rod 402. A connecting rope hole 405 is opened in the pressing block 404, and a pull rope 8 is wound and installed in the connecting rope hole 405.

[0026] In this embodiment, the pull ring 305 can drive the threaded post 303 to rotate, and the threaded post 303 is threadedly installed inside the threaded sleeve block 302. At this time, the safety pin 304 will be inserted into the limiting pin hole 403, thereby fixing the connecting rod 402 inside the limiting slide groove 301. The connecting rod 402 is fixed to the limiting slide rod 4, thereby fixing the limiting slide rod 4 inside the limiting slide groove 301. The pressing block 404 can drive the connecting rod 402 to move. Later, the pressing block 404 can be manually pushed to reset the limiting slide rod 4, so that the operator can replace the high-pressure gas cylinder 9 and reuse it. The end of the pull rope 8 is wrapped inside the connecting rope hole 405. The pulling rope 8 can quickly drive the pressing block 404, and the connecting rod 402 drives the limiting slide rod 4 to move. The sealing gasket 406 will abut against the inner wall of the limiting slide groove 301, restricting the airflow from slowly leaking from the gap between the connecting rod 402 and the limiting slide groove 301.

[0027] The working principle and usage process of this invention are as follows: The high-pressure gas cylinder 9 is installed on the gas cylinder connector 101. Before use, the threaded post 303 needs to be manually rotated using the pull ring 305 to unscrew it from the threaded sleeve block 302. At this point, the safety pin 304 can be moved out of the limiting pin hole 403 directly through the pull ring 305, thus contacting the safety mechanism of the device. During use, the pull rope 8 is held and pulled forcefully. The pull rope 8 can move the limiting slide rod 4 through the pressing block 404 and the connecting rod 402. The roller 401 will move to the inner side of the valve body 1, releasing the restriction on the gasket 5. At this time, the sealing ball head 501 will be pushed backward by the high-pressure gas, and the gas can be directly rushed into the life ring through the valve body 1 to realize the rapid inflation of the life ring. After the air pressure between the high-pressure gas cylinder 9 and the life ring is balanced, the return spring 503 will push the gasket 5 upward. The gasket 5 will drive the sealing ball head 501 to re-fit against the edge of the sealing ring 102, re-sealing the internal passage of the valve body 1 to prevent the gas inside the valve body 1 from leaking out.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
