The placement part 302 is arranged on the installation part 301 and is detachably connected to the installation part 301. The placement part 302 is provided with several gas cylinder clamping structures 303 for fixing gas cylinders.

[0040] When the present invention is in use, the gas cylinder to be tested can be placed upside down on the placement portion 302, and the gas cylinder can be fixed by the gas cylinder clamping structure 303. Then, the height of the fixing component 30 can be adjusted by the lifting component 20, so that the gas cylinder valve on the inverted gas cylinder can be immersed in the test liquid in the test pool 10. Then, by observing whether bubbles emerge in the test liquid near the gas cylinder valve on each gas cylinder, the air tightness of the gas cylinder valve can be judged. Compared with the traditional gas cylinder valve detection device, the present invention can detect multiple gas cylinder valves at the same time, which solves the problem that the current gas cylinder valve detection device can only detect one gas cylinder valve at a time and has low detection efficiency.

[0041] like Figure 3 As shown, in order to facilitate the rapid fixation of the gas cylinder, this embodiment is modified on the basis of the above embodiment.

The driving cylinder 203 is arranged on the top of the fixed plate 201, and the output end of the driving cylinder 203 passes through the fixed plate 201 and is slidably connected to the fixed plate 201. The guide column 205 is arranged on the top of the fixed plate 201, and one end of the guide column 205 passes through the fixed plate 201 and is slidably connected to the fixed plate 201.
