Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 to Figure 3, this automobile exhaust pipe, including：
Hole pipe 1, is equipped with several bloops 11, several described bloops 11 are uniformly arranged along helical trajectory；
Baffle pipe 2 is connected and is obliquely installed with 1 left end of hole pipe, is equipped with several baffles 21 in baffle pipe 2, and any two
The spacing of a adjacent screen 21 is equal and is staggered up and down, and baffle 21 at least covers the 1/2 of 2 section of baffle pipe；
Socket 3, left and right ends are inserted in hole pipe 1 and are connected, 3 left end of socket and 1 left alignment of hole pipe, socket 3 or so two
End and the junction of hole pipe 1 seal, and 3 mid diameter of socket is greater than the diameter at its both ends, and bloop 11 is covered in the middle part of socket 3
Arrangement range；
Connecting flange 4 is set to 3 right side of socket, and connecting flange 4 is inserted in 1 right end of hole pipe and is connected, and connecting flange 4 is in circle
Shape and two sides are respectively equipped with the lug 41 of arc-shaped, and the lug 41 is equipped with connecting hole.
When vehicle exhaust is extraneous by the discharge of this exhaust pipe, the closing silencing cavity being made of hole pipe 1 and socket 3 is first passed through,
Reflection, interference occur in silencing cavity for noise, to reduce noise；Then when tail gas passes through baffle pipe 2, baffle 21 makes pipeline
Section mutates, and noise is more difficult to propagate in baffle pipe 21, this exhaust pipe is preferably provided with multiple staggered baffles 21 up and down, and
Baffle 21 at least covers the 1/2 of 2 section of baffle pipe, so that the acoustic resistance of baffle pipe 2 be made to further increase, erasure effect is more preferable, when
When baffle number is more, erasure effect is better；The spacing of any two adjacent screen 21 is equal, when making noise by baffle pipe 2,
Noise is easier to interfere counteracting.In addition, several bloops 11 are arranged to semicircle and are uniformly arranged along helical trajectory,
Make noise in a limited space in occur it is more reflect and interference, the erasure effect of exhaust pipe is more preferable.This automobile exhaust pipe
Structure is simple, good muffling effect, and without using quieter material, at low cost.
When automobile wading operation, the incline structure and baffle 21 of baffle pipe 2 can also make water flow and foreign matter be not easily accessible row
Tracheae improves the reliability of exhaust pipe.
When this exhaust pipe manufactures, socket 3 is first inserted in hole and manages and welds connected, 3 left end of socket is flushed with 1 left end of hole pipe
Structure keeps welding positioning more convenient；Then the right end of baffle pipe 2 and the left end oblique weld of hole pipe 1 are connected, the welding position
Install the double-layer structure of perforated pipe 1 and socket 3, welding position be unlikely to deform and weld it is more firm；In addition 3 both ends of socket are in
Portion's tapering transition, welding high temperature, which is not easy to be transferred in the middle part of socket 3, to be caused to deform, to guarantee the erasure effect of exhaust pipe；Secondly
Connecting flange 4 is inserted in the right end of hole pipe 1 and welded and is connected, connecting flange 4 and the right end of socket 3 are spaced apart, to weldering
Rifle position, which is set, reserves certain working space, so that it is relatively reliable to weld connecting flange 4 with hole pipe 1.
Pipe 4 right end in hole stretches out connecting flange 4, and extension is equipped with several circumferential equally distributed rectangular apertures 12, this
Exhaust pipe is connect by connecting flange 4 with other pipeline threads, and when connection is installed, pipe 4 right end extension in hole is embedded in other pipes
The one end in road, while other pipelines are equipped with protrusion corresponding with rectangular aperture 12, thus keep pipeline alignment more convenient, wherein
The quantity of rectangular aperture 12 is preferably three, makes corresponding lug boss be not easy to skid off rectangular aperture 12, in addition by one of them
Right above rectangular aperture 12 is set to, facilitate the installation site of installation personnel identification exhaust pipe, it is easier for installation.
It is extended with tapered protrusion along connecting hole outer, is carried out by installation site of the tapered protrusion to exhaust pipe more accurate
Positioning, keeps the junction sealing effect of exhaust pipe and other pipelines more preferable.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
