[0002] After the metal sealing ring is produced, it needs to be sampled and tested to prevent defects in the quality of the metal sealing ring. At present, the sealing test of the metal sealing ring mainly focuses on the airtightness test. There are still certain problems in the use of traditional airtightness test devices. The metal sealing rings tested by traditional airtightness test devices generally have a certain size. However, the diameters of metal sealing rings are large and small, and they cannot be adapted to different metal sealing rings during use, resulting in poor applicability. In addition, the functions of traditional test devices are relatively single. The flatness of the surface of the metal sealing ring is also an important part of the test and detection of the metal sealing ring, and it cannot perform surface flatness detection while conducting the sealing test, resulting in poor functionality.

One end of the air duct 5 penetrates through the top of the pressure plate 4 and is equipped with a rotary joint 7. A bracket 8 is installed on the surface of the cavity 1. Through the design of the placement plate 2 and the rubber pad 3 inside the cavity 1, after the metal ring is placed on the rubber pad 3, the downward pressure of the pressure plate 4 can drive the spherical ball 6 to press down, so that the surface of the spherical ball 6 contacts the inner edge surface of the metal ring. When an external air supply device is connected to the rotary joint 7 to supply air, the gas enters the internal space of the metal ring through the air duct 5 to achieve the purpose of detection. And due to the spherical ball 6, its surface can contact metal rings with different diameters, improving the applicability during the test.

The downward pressure of the pressure plate 4 can drive the spherical ball 6 to press down, so that the surface of the spherical ball 6 contacts the inner edge surface of the metal ring. When an external air supply device is connected to the rotary joint 7 to supply air, the gas enters the internal space of the metal ring through the air duct 5. When there is insufficient airtightness, there will be air leakage at the contact point between the metal ring and the spherical ball 6, and bubbles will be generated in the water body to achieve the purpose of detection. And due to the spherical ball 6, its surface can contact metal rings with different diameters, improving the applicability during the test.
