An engine oil dipstick hole sealing device

Abstract

The invention provides a sealing device for an oil level gauge hole of an engine. The sealing device comprises a pull rod, a sleeve, a gas-type fitting, a seal cartridge and a handle, wherein the pull rod is provided with a sealing end and a connecting end, a gas charging hole is formed in the pull rod, and a connection hole communicated with the gas charging hole is formed in the surface of the pull rod; the sleeve sleeves the pull rod and is in sliding fit with the pull rod, and the sealing end and the connecting end are both outside the sleeve; the gas-type fitting is fixedly connected with the sleeve, and an inner hole of the gas-type fitting is communicated with the connection hole; the seal cartridge sleeves the sealing end, and end surface of the seal cartridge abuts against the sleeve; and the handle is provided with a cam part in rotational connection with the connecting end. According to the sealing device for the oil level gauge hole of the engine, as the seal cartridge sleeves the sealing end of the pull rod, during use, the sealing end and the seal cartridge are inserted into the oil level gauge hole at first, the end surface of the sleeve abuts against the oil level gauge hole, then the handle is rotated to enable the pull rod to move relative to the sleeve in the direction far away from the oil level gauge hole, at the moment, the seal cartridge is extruded to be deformed to block off the oil level gauge hole, and accordingly, the purpose of sealing the oil level gauge hole of the engine is achieved.

Description

technical field [0001] The invention relates to the field of air tightness detection of an automobile engine oil channel, in particular to a sealing device for an engine oil dipstick hole. Background technique [0002] At present, the plugging of the orifice of the oil dipstick for engine oil passage leakage test is generally carried out by the end face sealing method, that is, the sealing ring is used to block the processing surface of the orifice end of the engine oil dipstick hole, and the processing surface is generally smaller in size. If it is small, it is easy to have insufficient sealing when plugging, which will cause air leakage during the engine oil passage seal test, which will affect the test effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an engine oil dipstick hole sealing device which can effectively seal the engine oil dipstick hole. [0004] In order to solve the above technical problem...
