Abstract

The invention belongs to the field of auto oil pipe fixing devices, and particularly relates to an auto oil pipe positioning mechanism which comprises an oil filling pipe, a carbon tank breather pipe and an oil filling breather pipe, wherein the oil filling pipe is communicated with the oil filling breather pipe, a positioning fixed part is arranged at the end part of the oil filling pipe, the carbon tank breather pipe is fixed on the side surface of the oil filling breather pipe through a connecting piece, the connecting piece comprises a dust cap and a connecting piece, the dust cap is fixed at the end part of the connecting piece, the dust cap covers the pipe orifice of the carbon tank breather pipe, the positioning fixed part is in interference fit with the oil filling pipe and is welded and fixed, and a positioning pin and an arc positioning strip are arranged at the two ends of the positioning fixed part. The auto oil pipe positioning mechanism provided by the invention has the advantages that the positioning is accurate, the fixing and matching effects of the dust cap are excellent, and the positioning accuracy of the oil pipe and the dust preventing effect of the carbon tank breather pipe are improved.

Description

Technical field [0001] The invention belongs to the field of automobile oil pipe fixing devices, in particular to an automobile oil pipe positioning structure. Background technique [0002] There are basically three types of automobile fuel pipes. The gasoline pipe connects the gasoline pump and the engine injector to provide fuel. There is also a booster oil pipe, which provides booster oil for the steering gear, so as to reduce the steering resistance. The brake hose is connected to the brake pump and the top post of the brake pad. When we step on the brake, the brake pump will pressure the brake pads through the brake hose, and the two brake pads squeeze the brake disc to achieve the purpose of decelerating and stopping the car. [0003] With the development of the automobile industry, people have higher and higher requirements for the quality, performance, fuel consumption and noise of the car. For the fuel filler pipe with a seal ring on the head, the fuel filler pipe is inst...
