[0004] In the prior art, improvements have also been made to the joint assembly of the high-pressure gas cylinder. However, because the internal pressure of the high-pressure gas cylinder is very high, it is still laborious to manually insert and remove the female and male heads of the pneumatic self-locking quick connector, and gas will occur. Leakage, especially when high-pressure gas cylinders store toxic gases, there is a greater potential safety hazard

Provided are a plugging device and method of a quick connector of a high-pressure air cylinder and high-pressure air source equipment. The device comprises a second hand vise arm assembly, and one end of the second hand vise arm assembly is rotationally connected with one end of a first hand vise arm assembly. When the second hand vise arm assembly is combined with the first hand vise arm assembly, a male connector storage portion is combined to a female connector storage portion so that a male connector assembly and a female connector assembly can be assembled; or, when the second hand vise arm assembly is separated from the first hand vise arm assembly, the male connector storage portion is moved away from the female connector storage portion so that the male connector assembly and the female connector assembly can be separated. Compared with the assembly mode of holding a female connector and a male connector with hands in the prior art, labor is saved, and the assembly efficiency is improved. In addition, as people do not need to make contact with the female connector and the male connector directly, the potential safety hazard caused by gas leakage of the high-pressure air cylinder can be effectively reduced.
Description
technical field [0001] The invention relates to the field of high-pressure power equipment, in particular to a high-pressure gas cylinder quick joint plugging device, method and high-pressure gas source equipment. Background technique [0002] As a gas storage container, high-pressure gas cylinders are widely used in hospitals, factories, automobile filling stations, etc. The gases stored in high-pressure gas cylinders include air, nitrogen, oxygen, carbon dioxide, natural gas, hydrogen, etc. Seal the high-pressure gas cylinders. In most cases, the high-pressure gas cylinders are sealed with pneumatic self-locking quick connectors. [0003] This kind of joint has good sealing performance, is safe and reliable. However, in the prior art, the connector needs to be manually inserted and removed. During the specific operation process, it is necessary to hold the locking sleeve with one hand, slide the locking sleeve down to the limit position, and insert the male quick connecto...
