The gasket 11 is a part to be detected and does not belong to the structure of the sealing gasket sealing detection device. The marking is to facilitate the understanding and description of the scheme. The bottom of the lower pressing member 16 extends out of the bottom of the workbench 1. A sealed box 3 is arranged on the top of the lower pressing member 16. A barometer 4 is fixedly connected to the top of the sealed box 3. The barometer 4 detects the air pressure change inside the sealed box 3. The top of the inner wall of the sealed box 3 is fixedly connected to the upper pressing member 2. The bottom of the lower pressing member 16 is connected to a delivery pipe 15. The other end of the delivery pipe 15 is connected to an air pump 14. The top of the air pump 14 is fixedly connected to the bottom of the workbench 1.

[0024] In the specific implementation process, it is worth pointing out that when the gasket 11 needs to be tested, the gasket 11 is placed on the top of the lower pressure piece 16, and then the sealing box 3 is moved downward by the driving device, so that the sealing box 3 and the workbench 1 form a sealed space. When the sealing box 3 moves downward, the upper pressure piece 2 is pressed against the top of the gasket 11, and then the air pump 14 is started to inflate the inside of the sealing box 3. If the gasket 11 leaks, the gas will enter the sealing box 3 from the leakage area. When the air pressure in the sealing box 3 changes, the barometer 4 will change, thereby testing the gasket 11 without wasting the testing cost.

[0025] Furthermore, an annular groove 12 is provided on the top of the workbench 1, and the inner wall bottom of the annular groove 12 is covered with a rubber sealing layer 13, and the rubber sealing layer 13 can ensure that the area formed between the sealing box 3 and the workbench 1 is a sealed area to prevent gas from flowing out;

[0026] In the specific implementation process, it is worth pointing out that when the sealing box 3 moves downward, it is finally inserted into the annular groove 12 opened on the top of the workbench 1, and a sealed space is formed inside the sealing box 3. The rubber sealing layer 13 can ensure that the area formed between the sealing box 3 and the workbench 1 is a sealed area to prevent gas from flowing out;

[0027] Specifically, when using the sealing gasket sealing detection device, when the gasket 11 needs to be detected, the gasket 11 is placed on the top of the lower pressure piece 16, and then the sealing box 3 is moved downward by the driving device, and finally inserted into the annular groove 12 opened on the top of the workbench 1, and a sealed space is formed inside the sealing box 3. The rubber sealing layer 13 can ensure that the area formed between the sealing box 3 and the workbench 1 is a sealed area to prevent gas from flowing out. When the sealing box 3 moves downward, the upper pressure piece 2 is pressed against the top of the gasket 11, and then the air pump 14 is started to inflate the inside of the sealing box 3. If the gasket 11 leaks, the gas will enter the sealing box 3 from the leakage area.
