Abstract

The invention relates to an air tightness test fixture, which comprises a storage seat, a driver, a push plate, an ejector rod and an elastic test assembly, and is characterized in that a groove is formed in the storage seat, the groove is provided with an opening, and a product to be tested is assembled at the opening of the groove; the driver is in transmission connection with the push plate, the ejector rod is fixedly connected to the push plate, the elastic test assembly is movably connected to the push plate, the push plate is arranged corresponding to the storage seat and suspended abovethe storage seat, and the driver drives the push plate to move in the direction close to or away from the storage seat to drive the ejector rod and the elastic test assembly to be close to or away from the storage seat; the elastic test assembly comprises a supporting rod, a rubber plug and an elastic piece, a through hole is formed in the push plate, and the supporting rod is assembled and fixedin the through hole and movably connected to the push plate; the rubber plug is arranged at the end, away from the push plate, of the supporting rod and used for sealing the through hole; and one endof the elastic piece abuts against the push plate, and the other end abuts against the end, provided with the rubber plug, of the supporting rod. The air tightness test fixture can carry out air tightness test on a product with a through hole.

Description

technical field [0001] The present application relates to the field of airtightness testing, in particular to an airtightness testing jig. Background technique [0002] The airtight test is to test the sealing of the product to prevent the occurrence of defective products to meet the design requirements. For some products with a cavity covered by a cover, there may be other through holes such as screw holes on the cover for installing and fixing parts. The airtightness of the lower part and the cover is enough. The airtightness of the lower part is better tested. It only needs to use a rubber tree with an opening in the cavity. For the cover, since there are other through holes , It is difficult to test the airtightness of the edge of the cover, and it is also difficult to conclude whether the contact position is sealed when the cover is closed on the lower part. Therefore, for the airtightness test, when the product to be tested is provided with a through hole, the airtig...
