Abstract

The utility model relates to a double catalytic converter installation structure of a silencer, which comprises a catalytic converter fixing pipe (1) and two catalytic converters (2 and 3). A plug welding hole (4) is disposed respectively at the position of the pipe wall of the catalytic converter fixing pipe (1) corresponding to each of the catalytic converters (2 and 3). The catalytic converters (2 and 3) and the catalytic converter fixing pipe (1) are fixedly welded by welding rods through the plug welding hole (4). The double catalytic converter installation structure of the silencer has the advantages of avoiding radial and axial motion of the catalytic converters in the catalytic converter fixing pipe, and improving efficiency of purifying exhaust gas of the catalytic converters.

Description

The two catalytic converter mounting structures of silencing apparatus

Technical field

The utility model relates to a kind of motorcycle part, is specifically related to the two catalytic converter mounting structures of a kind of silencing apparatus.

Background technique

Two catalytic converters of existing silencing apparatus are contained in silencing apparatus and connect in the catalytic converter fixed tube at mouth of pipe place; Owing to there is not the catalytic converter fixing device; Catalytic converter is done radial and axial motion in the catalytic converter fixed tube, the usefulness of catalytic converter purifying exhaust air is reduced.

The model utility content

The utility model technical problem to be solved just provides a kind of two catalytic converter mounting structures of silencing apparatus that can the fixed catalytic converter.

The utility model technical problem to be solved is to realize through such technological scheme; It includes catalytic converter fixed tube and two catalytic converters; The position of corresponding each catalytic converter respectively offers the plug welding hole on the tube wall of catalytic converter fixed tube, welds fixed catalytic converter and catalytic converter fixed tube through the plug welding hole with welding rod.

Owing to adopted technique scheme; The position of corresponding each catalytic converter respectively offers the plug welding hole on the tube wall of catalytic converter fixed tube; Weld fixed catalytic converter and catalytic converter fixed tube through the plug welding hole with welding rod; Avoid catalytic converter in the catalytic converter fixed tube, to do radial and axial motion like this, improved the usefulness of catalytic converter purifying exhaust air.The utlity model has following advantage: avoided catalytic converter in the catalytic converter fixed tube, to do radial and axial motion, improved the usefulness of catalytic converter purifying exhaust air.

Description of drawings

The description of drawings of the utility model is following:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the enlarged view of A portion among Fig. 1.

Among the figure: 1. catalytic converter fixed tube; 2. first catalytic converter; 3. second catalytic converter; 4. plug welding hole.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

As depicted in figs. 1 and 2; The utility model includes catalytic converter fixed tube 1 and two catalytic converters 2,3; The position of corresponding each catalytic converter 2,3 respectively offers plug welding hole 4 on the tube wall of catalytic converter fixed tube 1, through plug welding hole 4 usefulness welding rods welding fixed catalytic converter 2,3 and catalytic converter fixed tube 1.

Because the position of corresponding each catalytic converter 2,3 respectively offers plug welding hole 4 on the tube wall of catalytic converter fixed tube 1; Through plug welding hole 4 usefulness welding rods welding fixed catalytic converter 2,3 and catalytic converter fixed tube 1; Avoid catalytic converter 2,3 in catalytic converter fixed tube 1, to do radial and axial motion like this, improved the usefulness of catalytic converter 2,3 purifying exhaust airs.The utlity model has following advantage: avoided catalytic converter in the catalytic converter fixed tube, to do radial and axial motion, improved the usefulness of catalytic converter purifying exhaust air.

Claims

1. two catalytic converter mounting structures of a silencing apparatus; Include catalytic converter fixed tube (1) and two catalytic converters (2,3); It is characterized in that: the position of corresponding each catalytic converter (2,3) respectively offers plug welding hole (4) on the tube wall of catalytic converter fixed tube (1), welds fixed catalytic converter (2,3) and catalytic converter fixed tube (1) through plug welding hole (4) with welding rod.
