FIG. 5 is an operational state view showing an internal structure of a regulator for a high-pressure gas according to the present invention in a locked mode, and FIG. 6 is an operational state diagram showing an internal structure in a release mode of a regulator for a high-pressure gas according to the present invention.

The lock mode and the release mode of the present invention will be described with reference to FIGS. 5 and 6. FIG. First, when the high pressure gas container is not used, that is, in the locked mode, the actuating member 50 is positioned on the first concavo-convex portion 71 as shown in FIG. 5 so that the piston 30 is not in contact with the valve pin 5 So that the gas does not flow out to the outside and is kept in a sealed state in the high-pressure gas container.

Thereafter, when the user pulls the operation pin 60 in the axial direction D1, the mode is switched from the locked mode to the released mode by the following chain action, and the gas in the high-pressure gas container is discharged to the outside.

That is, when the actuating pin 60 is pulled in the axial direction D1, the actuating body 50 positioned on the first concave / convex portion 71 is pressed against the spherical back surface 73 moving in the first direction D1 Gradually downward in the vertical downward direction, and eventually the position is shifted onto the second concavo-convex portion 72 as shown in Fig.

As described above, when the operating body 50 is relatively moved on the second concave / convex portion 72, the operating body 50 compresses the elastic body 40, and the repulsive force resulting from the compression of the elastic body 40 is transmitted to the piston 30) to the vertical downward direction.

When the piston 30 is lowered by the repulsive force of the elastic body 40, the piston stem 32 positioned on the valve pin 5 presses the valve pin 5 to release gas in the high-pressure gas container.

The gas thus discharged is discharged into the flow path 19 of the upper hollow portion 12 through the hollow 81 of the boss 80 and then discharged to the outside through the gas outlet 14 communicating therewith.

On the other hand, when the operation pin 60 is pulled in the one lateral direction D1 for the release mode, the pulling portion 61 coupled to the operation pin 60 is released from the restraint by the first insertion hole 15, The projection 65 can be separated from the support platform 62 and the pulling portion 61 can be separated from the support platform 62. [

Accordingly, the next user or the manager can immediately recognize whether the high-pressure gas container is in an unused state or already used state by grasping only whether or not the pulling-out portion 61 has been removed.
