The push button portion 30 is hermetically coupled to the push button portion engaging groove 16 by an O-ring 37.

The push button unit 30 is an essential safety device for the gas filling device 1 according to the present invention, which is a case in which the filling container 100 is immediately removed after the high pressure gas is filled in the filling container 100. In order to prevent the high-pressure gas remaining in the upper space 11 from being blown out at high speed, the upper portion 11 and the upper portion 11 of the push button part 30, precisely, press one end of the valve body 35 protruding to the outside. By connecting the nozzle 15 connected to the nozzle 33 on the end side, the high pressure gas remaining in the upper space 11 is discharged to the outside to completely remove the internal pressure, and then to safely separate the filling container 100. do.

The used filling container 100 is screwed into the filling container coupling groove 18 formed on the other side of the body part 1, which is particularly large in pitch in order to eliminate the risk of inflow of high pressure gas. It is preferable to engage by the engagement of the threads.

As shown in FIGS. 1 and 5, the filling container 100 has a check valve at one side coupled to the filling container coupling groove 18 to prevent gas introduced into the filling container 100 from escaping to the outside. 101 is provided, and the other side is preferably provided with a discharge port 102 through which the filled gas can be discharged according to the purpose of use.

The adjusting handle part 40 is inserted into and coupled to the upper space 11 of the body part 10. As shown in FIGS. 1 and 6, one side has a gas flow path into the upper space 11. 42 is screwed to form and the other side is protruded to the outside and moving up and down the adjustment rod 41 for opening and closing the orifice 12, and the control dial 43 is coupled to the other end of the control rod 41 Include. Here, the control rod 41 is preferably maintained airtight by the O-rings (45, 46) on the upper side of the body portion (10).

In consideration of general use, the screwing of the adjusting handle part 40 rotates the adjusting dial 43 clockwise, and the adjusting rod 41 closes the orifice 12, and the adjusting dial 43 is rotated counterclockwise. It is preferable that the adjusting rod 41 be turned to open the orifice 12 when turned to.
