Structure the most effectively solves the problems referred to above.Such as Chinese patent Authorization Notice No. CN 201841941 U, authorized announcement date
On 05 25th, 2011, the entitled tail pipe decorating cover of innovation and creation, this Patent Case disclosed the knot of a kind of automobile tail pipe
Structure, by the isostructural combined innovation of inner and outer tubes, the structure of this tail pipe can reduce the exhaust noise of tailpipe, but
The interior crimping of this Patent Case is wrapped in tail frame, and when automobile tail pipe aerofluxus, tail gas has backflow phenomenon after running into interior crimping, can produce
Exhaust noise, however it remains the problem that exhaust noise is bigger.And for example Chinese patent Authorization Notice No. CN 202441471 U, authorizes
At on 09 19th, 2012 day for announcing, entitled a kind of automobile tail pipe of innovation and creation, this Patent Case discloses a kind of automobile tail pipe
Structure, by the isostructural combined innovation of inner tube, outer tube and projection, this tail pipe structure reduces the weight of finished product, but should
The end of the inner and outer tubes of Patent Case still uses the mode of welding to assemble, and there is cost height and low the asking of production efficiency
Topic.This utility model passes through the isostructural combined innovation of inner and outer tubes, it is provided that a kind of simple in construction, easy for installation, low cost,
Production efficiency is high, the little and widely used automobile tail pipe of noise.
Summary of the invention
This utility model solves the structure of general drive shaft in prior art, and the most effectively to solve cost height, production efficiency low
The problem big with noise, it is provided that a kind of automobile tail pipe, by the isostructural combined innovation of inner and outer tubes, it is achieved this automobile tail pipe
Having simple in construction, easy for installation, low cost, production efficiency is high, the little and widely used feature of noise.
In order to solve the technical problem of above-mentioned existence, this utility model takes following technical proposals: a kind of automobile tail pipe, bag
Including inner and outer tubes, described outer tube is socketed with inner tube, it is characterised in that the end of described outer tube is provided with crimping, said inner tube with
Crimping is in close contact, and forms the structure of interference fit, and the front end of inner tube fixes with outer tube.
Outer tube, simple in construction, it is used for protecting inner tube；Inner tube, simple in construction, the aerofluxus for vehicle exhaust saves；Outer tube interior
Side crimping, strengthens the intensity of outer tube, prevents outer tube from deforming；Crimping and the over-surplus fit structure of inner tube, instead of outer tube and inner tube
Welding Structure, as long as extruding socket can be realized as the assembling of outer tube and inner tube, cost of labor is low, and production efficiency is high, installs
Convenient；When automobile last person's gas, tail gas is directly discharged from inner tube, does not has the resistance of external tubular curl, and tail gas does not reflux, noise
Lower.
As preferably, the outer wall of said inner tube is in close contact with crimping.
As preferably, the inwall of said inner tube is in close contact with crimping.
As preferably, the end of said inner tube is provided with the horn mouth suitable with the inwall of crimping.This structure increases inner tube
With the contact area of crimping, connecting more reliable, noise is lower.
As preferably, the end of said inner tube is weldingly connected with crimping.
As preferably, the section of said inner tube is curved configuration.
As preferably, the section of said inner tube is polygonized structure.
As preferably, the section of said inner tube is regular polygon structure.Tail pipe is adjusted whole by the structure of inner tube section
The section structure of body, it is achieved this tail pipe is be applicable to the structure of different automobile exhaust pipes.
As preferably, the front end of described outer tube is provided with front breach, and the surrounding of described front breach is weldingly connected with inner tube.
As preferably, the middle part of described outer tube is provided with pit, is provided with breach, the surrounding of described breach and inner tube in pit
Outer surface is weldingly connected.
Owing to taking above-mentioned technical scheme, a kind of automobile tail pipe that this utility model provides has such useful effect
Really: by the isostructural combined innovation of inner and outer tubes, it is provided that a kind of simple in construction, easy for installation, low cost, production efficiency
Height, the little and widely used automobile tail pipe of noise.
