Referring to fig. 1 and 2, the manual plugging tool for the gas outlet of the gas pressure regulator 14 may include: the gas pressure regulating device comprises an end cover 1, wherein the end cover 1 is provided with a cavity 13, the cavity 13 is used for accommodating a gas outlet of a gas pressure regulator 14, and a plugging rubber ring 8 is arranged in the cavity 13; the piston assembly is used for moving towards the end cover 1 direction and extruding the plugging rubber ring 8 when driven by external force, so that the plugging rubber ring 8 is extruded and deformed to form sealing; and the driving handle 2 is positioned behind the piston assembly, and the piston assembly is driven to move towards the end cover 1 in the rotating process of the driving handle 2.
In this embodiment, the end cap 1 is used for being connected to an outlet of a gas pressure regulator 14, and forms a closed structure with the piston assembly by virtue of the internal cavity 13, so that the gas pressure regulator 14 can be plugged in the gas charging process, and the gas tightness detection is facilitated.
The piston assembly can move towards the end cover 1 under the driving of external force. In order to enhance the air tightness of the sealing structure formed above, in the present embodiment, a plugging rubber ring 8 is arranged in the cavity 13. In the process that the piston assembly moves towards the end cover 1, the plugging rubber ring 8 is continuously extruded, and when the plugging rubber ring 8 deforms, the sealing effect is improved. The air outlet of the fuel gas pressure regulator 14 is effectively blocked.
The driving handle 2 can be arranged behind the piston assembly, and the circumferential radiuses of the driving handle 2 are different, so that the driving handle can drive the piston assembly to move towards the end cover 1 when rotating, and extrude the plugging rubber ring 8, so that the plugging rubber ring 8 deforms, and a plugging seal is formed on the air outlet of the air conditioning compressor 14. Or, the piston assembly can be in contact connection with the piston assembly, and the driving handle 2 can be pressed in manually, so that the aim of driving the piston assembly to move towards the end cover 1 is fulfilled.
