[0026] The main body 100 has a rotating hole 200 on its surface, an internal thread 201 on its inner wall, a rotating rod 202 inside the rotating hole 200, an external thread 203 matching the internal thread 201 on the outer side of the rotating rod 202, a fixed block 204 at the outer end of the rotating rod 202, a sliding hole 205 on the fixed block 204, a sliding rod 206 sliding inside the sliding hole 205, handles 207 at both ends of the sliding rod 206, a rotating disk 208 at the inner end of the rotating rod 202, and a surface of the rotating disk 208 rotatably connected to the positioning block 209. A positioning groove 210 is provided on the surface of the positioning block 209. When in use, the cylinder valve is placed inside the device so that the valve inflation port is aligned with the position of the trachea 401. Then, the handle 207 is used to rotate the rotating rod 202 through the slide rod 206, so that the rotating rod 202 moves inside the rotating hole 200, thereby making the positioning block 209 close to the safety cap on the surface of the cylinder valve, so that the safety cap enters the positioning groove 210 on the surface of the positioning block 209. Then, the rotating rod 202 is continuously rotated to fix the cylinder valve inside the device and perform the inflation operation.

[0027] The connecting component includes an air hole 300, which is arranged on the outer surface of the main body 100. A mounting seat 301 is provided on the surface of the air hole 300. A connecting pipe 302 is provided on the surface of the mounting seat 301. The connecting pipe 302 is connected to the air hole 300. A sealing ring 303 is provided on the end surface of the connecting pipe 302. A limiting ring 304 is provided in the middle of the connecting pipe 302. A connecting sleeve 305 is provided on the outer side of the connecting pipe 302. The connecting sleeve 305 is located between the main body 100 and the limiting ring 304. When in use, the inflation head connected to the air pump is brought into contact with the connecting pipe 302, and then the connecting sleeve 305 is rotated so that the connecting pipe 302 and the inflation head are fixed, and the sealing ring 303 can ensure the sealing of the connection.

[0028] The sealing assembly includes a fixing seat 400, which is arranged on the inner surface of the air hole 300, and an air pipe 401 is provided on the surface of the fixing seat 400, and the air pipe 401 is connected to the air hole 300. A bracket 402 is provided on the inner wall of the air pipe 401, and a movable sleeve 403 is provided on the surface of the bracket 402. A spring 404 is provided at the bottom of the movable sleeve 403, and a limiting plate 405 is provided at the end of the spring 404. A push rod 406 is provided on the surface of the limiting plate 405, and a fixing plate 407 is provided on the inner wall of the air pipe 401. A through hole 408 is provided on the surface of the fixing plate 407, and a push rod 406 is provided inside the through hole 408. The diameter of the rod 406 is smaller than the inner diameter of the through hole 408, and a sealing plug 409 corresponding to the through hole 408 is provided in the middle of the push rod 406. During the fixing process of the cylinder valve, the valve inflation port contacts the air pipe 401, so that the valve inflation port squeezes the push rod 406, causing the push rod 406 to move toward the inside of the movable sleeve 403, so that the push rod 406 drives the sealing plug 409 to leave the through hole 408 and open the through hole 408. Since the diameter of the push rod 406 is smaller than the inner diameter of the through hole 408, the gas entering the air hole 300 can be ejected from the through hole 408 and then injected into the interior of the cylinder through the valve inflation port.

[0029] The above embodiment discloses a gas valve device that is adapted to the gas filling ports of various sizes of cylinders. When using this device, first, the gas filling head connected to the air pump is brought into contact with the connecting pipe 302, and then the connecting sleeve 305 is rotated so that the connecting pipe 302 and the gas filling head are fixed, and the sealing ring 303 can ensure the sealing of the connection. Then, the cylinder valve is placed inside the device so that the valve gas filling port is aligned with the position of the trachea 401. Then, the handle 207 is used to rotate the rotating rod 202 through the slide rod 206, so that the rotating rod 202 moves inside the rotating hole 200, thereby making the positioning block 209 close to the safety cap on the surface of the cylinder valve, so that the safety cap enters the positioning position. The positioning groove 210 on the surface of the block 209 is positioned inside the positioning groove 210, and the rotating rod 202 is continuously rotated to fix the cylinder valve inside the device, and the air pump is started to inflate the cylinder. During the fixing process of the cylinder valve, the valve inflation port contacts the air pipe 401, so that the valve inflation port squeezes the push rod 406, so that the push rod 406 moves toward the inside of the movable sleeve 403, so that the push rod 406 drives the sealing plug 409 to leave the through hole 408 and open the through hole 408. Since the diameter of the push rod 406 is smaller than the inner diameter of the through hole 408, the gas entering the air hole 300 can be ejected from the through hole 408 and then injected into the cylinder through the valve inflation port.

[0030] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
