Description

Motorcycle oil tank gas tightness detects instrument Technical Field The utility model relates to the field of oil tank testing equipment, in particular to a motorcycle oil tank air tightness detection tool. Background The fuel tank cap of a motorcycle is typically designed with a filler port for filling fuel and a fuel outlet port for delivering fuel to the engine. In the prior art, a butt joint positioning seat for a sealing joint is usually designed at an oil outlet, and the butt joint positioning seat plays a role in butt joint of an oil outlet pipeline. In the production test link, the butt joint positioning seat is often used for air tightness test, and is usually manually matched with a cover plate with a polyurethane sealing gasket, and is locked on the cover plate by an operator through a screw and a nut by a wind gun so as to fully fix and press the cover plate, thereby blocking the oil outlet to form a seal. In the detection process, a leak tester needs to plug a connector from an oil filling port, and compressed air is injected into an oil tank to perform an airtight test. After the test is completed, the screw and nut are removed by another operator.
