Description

A connection structure of air intake aluminum pipe

technical field

The utility model belongs to the technical field of automobile pipelines, and relates to a connection structure of intake aluminum pipes.

Background technique

The intake aluminum pipe of the engine is one of the important pipelines of the engine, which is used for exhaust gas recovery. The engine intake aluminum pipe of the prior art is generally mainly composed of steel pipes and sleeves welded. After long-term use, the air-tight reliability of the air intake aluminum pipe of the prior art will deteriorate, there will be hidden dangers of corrosion, and it will have a great impact on the cleanliness of the pipeline, which will easily cause blockage. For this reason, a This kind of rubber sleeve and aluminum tube is tightly fitted into the engine intake aluminum tube, but the problem is that the intake aluminum tube of this structure is not reliable enough, and the rubber sleeve and aluminum tube are easy to disengage, which affects the gas flow of the pipeline. Tightness.

Contents of the invention

The purpose of this utility model is to provide a connection structure of intake aluminum pipes for the above problems in the prior art, and the technical problem to be solved is how to improve the firmness and air tightness of the intake aluminum pipes.

The purpose of this utility model can be achieved through the following technical solutions: a connection structure of an intake aluminum pipe, the intake aluminum pipe includes a body and a rubber sleeve, and the feature is that the connection structure includes a compression ring and an annular snap ring, so that The end of the body has an annular rim, and the middle of the inner wall of the rubber sleeve has an annular shoulder. The end of the body is passed through the rubber sleeve, and the compression ring is located In the tube, and the compression ring is screwed with the rubber sleeve so that the annular retaining edge and the annular retaining shoulder are snapped together, and the annular snap ring is embedded and fixed on the outer wall of the rubber sleeve so that the body and the rubber sleeve Phase solid connection.

The rubber sleeve has a certain degree of elasticity. One end of the body passes through the rubber sleeve, and the ring-shaped retaining edge at the other end of the body engages with the ring-shaped retaining shoulder in the rubber sleeve. Tighten the ring, make the compression ring lean against the annular retaining edge to engage the annular retaining edge and the annular retaining shoulder, and then insert and fix the annular snap ring on the outer wall of the rubber sleeve so that the body and the rubber sleeve are firmly connected . Through the cooperation of the compression ring and the annular snap ring, the firmness of the connection between the body and the rubber sleeve is improved, the body and the rubber sleeve will not be separated, and the airtightness is improved.

In the connection structure of the above-mentioned air intake aluminum pipe, the outer wall of the rubber sleeve has an annular locking groove, and the annular snap ring is embedded and fixed in the annular locking groove. The arrangement of the annular snap groove can improve the firmness of the installation of the annular snap ring, thereby improving the firmness of the connection between the body and the rubber sleeve, so that the body and the rubber sleeve will not be separated, and the airtightness is improved.

In the above connection structure of the intake aluminum pipe, the annular snap ring is a split snap ring. Split snap ring for easy installation.

In the above connection structure of the intake aluminum pipe, the compression ring is made of plastic material. The compression ring cooperates with the rubber bushing for easy installation.

Compared with the prior art, the connection structure of the intake aluminum pipe provided by the utility model improves the firmness of the connection between the body and the rubber sleeve through the cooperation of the compression ring and the annular snap ring, so that the body and the rubber sleeve will not be separated , improve airtightness.
