[0002] Gas cylinders are used as mobile gas sources to store gas at a certain pressure during use. Gas cylinders should be safe and reliable. When storing gas, they are required to have high pressure resistance and low leakage during long-term storage. After the gas cylinder is inflated, it is often necessary to conduct a leakage test on the gas cylinder to ensure the sealing of the gas cylinder.

[0003] For example, a gas cylinder leakage test device with publication number CN216789872U can seal, wrap and fix the test gas cylinder through an upper sleeve, a lower sleeve and a back nozzle, and leave a corresponding detection interface, so that the gas cylinder as a whole can be leaked.

However, when testing gas cylinders, the above detection methods are generally unable to quickly detect a number of gas cylinders, and the testing process is complicated and cumbersome, and the test work efficiency is low. For this reason, a gas cylinder leakage test device is proposed for improvement. Utility Model Content
