[0025] Based on the above structure, the detection plastic tank body is fixed by a fixing component, and the tank mouth is sealed by a sealing component, the box door 3 is closed to seal the entire box body 2, and then the vacuum pump 6 is started, and the vacuum pump 6 sucks out the gas in the box body 2 through the suction pipe 8, so that a negative pressure environment is formed in the box body 2, and the current pressure in the box body 2 is recorded through the pressure detector 9 and the pressure gauge 10, and then the air pump 4 is started, and the air pump 4 injects the detection gas into the plastic tank body through the gas injection pipe 7, the hose 11 and the sealing hose 18, and at the same time observes whether the data displayed on the pressure gauge 10 fluctuates, so as to determine whether the plastic tank body has an airtightness problem.

[0026] like Figure 3 As shown, the fixing assembly includes a mounting block 13, which is mounted on the upper side of the base plate 1. An adjusting groove is provided on the upper side of the mounting block 13, in which two adjusting blocks 14 are slidably installed. A fixing block 15 is installed on the upper side of the two adjusting blocks 14. A driving hole is provided on one side of the mounting block 13, in which a driving unit is installed. The internal metal structure surface of the two fixing blocks 15 includes rubber material, and the rubber material is used to protect the surface of the plastic tank body from wear due to the clamping effect.

[0027] Example 2

[0028] like Figure 3 As shown, the driving unit includes a bidirectional threaded rod 16, and the non-threaded area on the surface of the bidirectional threaded rod 16 is rotatably installed in the driving hole. The two adjustment blocks 14 are both screwed and installed in the threaded area on the surface of the bidirectional threaded rod 16. A rotating knob 17 is installed at one end of the bidirectional threaded rod 16. The bidirectional threaded rod 16 is a prior art, and there are two threaded areas on its surface, and the two threaded areas are in opposite directions.

[0032] Working principle of this utility model:

[0033] When using the device, the user first places the plastic can body to be inspected on the mounting block 13, and rotates the rotating knob 17, which drives the bidirectional threaded rod 16 to rotate, and the bidirectional threaded rod 16 drives the two adjusting blocks 14 to move closer to each other, and the two adjusting blocks 14 drive the two fixing blocks 15 to move closer to each other, so as to clamp and fix the plastic can body, and then pulls the sealing cover 12 downward, so that the sealing rubber tube 18 in the sealing cover 12 is tightly attached to the outer ring of the plastic can mouth to seal the can mouth, and drives the two extrusion sheets 20 to move closer to each other through the two springs 19, so that the two extrusion sheets 20 are respectively driven to move closer to each other, and the two extrusion sheets 20 are driven to move closer to each other. The pressing sheet 20 squeezes the sealing hose 18 to further improve the sealing performance. Then, the box door 3 is closed and the vacuum pump 6 is started. The vacuum pump 6 sucks out the gas in the box body 2 through the suction pipe 8 to form a negative pressure environment in the box body 2. The pressure detector 9 detects the current pressure information inside the box body 2 and displays it on the pressure gauge 10. The current pressure in the box body 2 is recorded and the air pump 4 is started again. The air pump 4 injects the detection gas into the plastic tank body through the gas injection pipe 7, the hose 11 and the sealing hose 18. At the same time, observe whether the data displayed on the pressure gauge 10 fluctuates, and then determine whether the plastic tank body has an airtightness problem.
