The utility model aims at solving the following problems existing in the prior art: the existing airtight detection equipment is used for detecting a container, the detected side object is directly placed inside the container filled with liquid, the top cover covers the container, at the moment, the container is vacuumized by an air extractor, bubbles can be generated when the object tightness is detected to cause problems, the air pressure in the container changes, but the object is not detected completely by the liquid, the detection result is invalid due to the fact that the bubbles cannot be generated in the detection process when the air extractor works, the rejection rate is increased, and the processing cost is improved.

For solving the problem that prior art exists, the utility model provides an airtight check out test set of pressure vessel, including container and air exhaust device, the container top is provided with the closing cap, and closing cap bottom fixedly connected with connecting rod, the movable plate has been cup jointed in the connecting rod outside, movable plate bottom fixedly connected with spring, spring other end fixedly connected with layer board.

Preferably, the top of the sealing cover is provided with a connecting nozzle, the top of the connecting nozzle is provided with an air pipe, the top of the sealing cover is provided with a handle, and a closed rubber ring is arranged between the sealing cover and the container and connected with the sealing cover.

Preferably, the air pumping device consists of an air pump and a control device, and the output end of the air pump in the air pumping device is connected with the air pipe.

Preferably, the four connecting rods are arranged on the sealing cover in a rectangular shape, and the four connecting rods penetrate through the moving plate and are connected with the supporting plate.

Preferably, the surfaces of the moving plate and the supporting plate are both provided with through holes.

Preferably, the number of the springs is four, the springs are respectively arranged at the outer sides of the four connecting rods, and the four springs are in a compressed state.

Preferably, the moving plate has the same diameter as the support plate, but a diameter smaller than the inner diameter of the container.

Compared with the prior art, the invention has the beneficial effects that:

the utility model discloses a to the inside instillation liquid of container place the article that will detect again at the layer board top, move down the movable plate under the effect of spring and be pulled to the layer board direction, with the layer board top wait that detect article centre gripping fixed, again with closing cap to container top, wait to detect that the whole body of article is submerged back to use air exhaust device to take out to the vacuum with the container is inside, take off the closing cap after the use and can directly take off with detecting article, need not stretch the hand to the liquid in, the utility model discloses simple structure, convenient operation detects article and is surveyed more easily and have the leakage condition, reduces the rejection rate, reduces the processing cost.
