An automobile lamp airtightness detection device
This invention discloses an automotive headlight airtightness testing device, relating to the field of airtightness testing. This device utilizes an inflatable airbag that, when inflated, elastically bulges. This bulge, in conjunction with an air guide mechanism pressing against the outside of the headlight insertion hole, seals the hole. The inflated airbag bulges, causing a sliding ring to move upwards. This internal expansion of the airbag exerts upward pressure, creating a clamping effect with the air guide mechanism. Under this clamping pressure, a seal is formed at the insertion hole. Compared to existing airtightness testing equipment, this device achieves sealing by applying downward pressure, reducing pressure on the overall headlight structure. This prevents errors in the test results caused by small vents within the headlight structure being sealed under downward pressure.
