Description
Technical field
The utility model relates to a kind of link, particularly relates to a kind ofly connecting firm pipe joint.
Background technique
Existing oil connection is often due to reasons such as its connection are not firm, sealing is poor, oil pipe is caused easily to be deviate from from oil connection, cause the fuel leakage in oil pipe or splashing, because outlet pipe during internal combustion engine, pressurized machine surface temperature are higher, so once occur that leakage of oil is splashed on outlet pipe, pressurized machine, may serious accidents such as catching fire be caused.
