Cylinder is connected.
As a kind of preferred scheme, it is provided with second sealing container and coordinates peace for workpiece for measurement sealing
The recess of dress, first sealing container is concavely provided with the annular groove being adapted with foregoing recess so that
First sealing container, the second sealing container and workpiece for measurement are fitted close and are installed together.
Used as a kind of preferred scheme, the Pneumatic adjusting mechanism also includes the pressure for showing pressure size
Table, the cylinder is connected with pressure gauge and connects wireway.
Used as a kind of preferred scheme, the cylinder drives the first sealing container to move up and down, and makes it with second
Sealing container forms sealed chamber.
Used as a kind of preferred scheme, the floor push is arranged on the lower section of support, and the cylinder is by leading
Line is connected with floor push.
Compared with prior art, the good effect that has of the present invention is：
The present invention is put into the first closed container and the second closed container by by injection oil bottle cap closed
Among, it is inflated using cylinder, and coordinate using transparent water pot, if there is bubble to emerge in water pot,
Prove that the injection oil bottle cap air-tightness is unqualified, if conversely, no bubble is emerged in water pot, it was demonstrated that the note
Modeling oil bottle cap air-tightness is qualified, so more intuitively realizes the air tightness test of injection oil bottle cap, even if
It is that trickle stomata can also be easier to intuitively be detected so that test jobs are easy to operate, reliability
It is good, working efficiency greatly improved, brought convenience to enterprise's production, and effectively reduce the production of enterprise
Cost.

Specific embodiment
As shown in figure 1, the present invention provides a kind of new airtight test device, including support 1 and air pressure are adjusted
Section mechanism, Pneumatic adjusting mechanism includes cylinder 2, pressing plate 3 and power transmission shaft 4, and cylinder 2 is arranged at pressing plate 3
Upper surface on, cylinder 2 is connected by wire with the floor push 5 of the lower section for being arranged on support 1, lead to
The control cylinder 2 of floor push 5 is crossed, it is simple and convenient.
The piston rod and power transmission shaft 4 of cylinder 2 are connected, and the lower end of power transmission shaft 4 is fixedly connected the first sealing appearance
Device 6, the piston rod of cylinder 2 drives power transmission shaft 4 upwardly or downwardly to move, and then drives first to seal
Container 6 is upwardly or downwardly moved.Correspond in the centre of support 1 and be provided with first sealing container 6
