Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to thoroughly understand the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened is fully disclosed to those skilled in the art.
Fig. 1 to Fig. 3 shows the structural representation for the enmgine exhaust that embodiment according to the present utility model provides
Figure.As shown in Figure 1 to Figure 3, this enmgine exhaust includes downtake pipe 1, second exhaust pipe 2 and is used to connect first
One end of the expansion joint 3 of exhaust pipe 1 and second exhaust pipe 2, expansion joint 3 is fixedly connected with downtake pipe 1, expansion joint 3 it is another
One end is fixedly connected by clamping mechanism with second exhaust pipe 2, and diversion pipe 11 is integrated on downtake pipe 1.
Specifically, the main body of expansion joint 3 is circular bellows 31, and one end and the downtake pipe 1 of expansion joint 3 are welded on
Together, the other end of expansion joint 3 is connect by clip 4 with second exhaust pipe 2.Downtake pipe 1 and second exhaust pipe 2 are passed through
Expansion joint is tightly connected, and one end of expansion joint 3 and exhaust pipe are welded, and the other end is connected by clip 4, i.e., one end is solid
