The first limiting stand fastened with the annular spacing groove and the second limiting stand engaged with air inlet tube end.
Preferably, the air inlet pipe between first limiting stand and second limiting stand is interference fitted with the inserting paragraph,
Its magnitude of interference is 0.5mm.
Preferably, the air inlet pipe is the pyramidal structure tapered into along the airintake direction diameter of axle.
Preferably, first limiting stand is wedge structure of the projection in air inlet tube end, before first limiting stand
End face it is concordant with the end face of the air inlet pipe and with the cascaded surface against the rear end face of first limiting stand stretches into annular limit
In the groove of position and with the end face of cascaded surface offside against.
Preferably, a buckling groove is also equipped with outside the air inlet pipe, the buckling groove is with the annular spacing groove in institute
State adjacent in the axial direction of escape pipe, clip is fixed with the buckling groove.
Preferably, the escape pipe is made up of injection moulding integrated molding.
Effect of the present utility model is：This programme is entered by stair-stepping closing component structure to escape pipe and turbocharger
Row pre-determined bit, is carried out sealed by the first limiting stand and the second limiting stand to the junction of escape pipe and turbocharger, it is ensured that
Junction connection is reliable, and escape pipe does not produce axial movement in junction, it is ensured that the reliability of connection.
Brief description of the drawings
, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art

Fig. 2 is the structural representation of escape pipe in the utility model embodiment.
Fig. 3 is escape pipe and the schematic diagram of turbocharger attachment structure.
In prior art diagram：1a- escape pipe 2a- clip 3a- turbocharger
In the present embodiment figure：1- turbocharger 2- escape pipe 3- annular spacing grooves the first limiting stands of 4- 5-
Second limiting stand 6- buckling groove 7- clips
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
Referring to a kind of escape pipe and the connection of turbocharger provided shown in Fig. 2 to Fig. 3 for the utility model embodiment
Structure, including turbocharger 1 and escape pipe 2, the end of escape pipe 2 is its inserting paragraph, and the turbocharger 1 has air inlet
Pipe, the inserting paragraph is interference fitted with the air inlet pipe；Wherein, the inserting paragraph is to become two grades of big ranks along the grafting direction diameter of axle
Ladder pipe, an annular spacing groove 3 is provided with the inserting paragraph along the step surface of two grades of ladder pipes；Along insertion in air inlet pipe
Direction is sequentially provided with the first limiting stand 4 fastened with the annular spacing groove 3 and second engaged with air inlet tube end is spacing
Platform 5.This programme carries out pre-determined bit by stair-stepping closing component structure to escape pipe and turbocharger, passes through the first limiting stand 4
The junction of escape pipe 2 and turbocharger 1 is carried out with the second limiting stand 5 sealed, it is ensured that junction connection is reliable, outlet
Pipe does not produce axial movement in junction, it is ensured that the reliability of connection.
Wherein, the air inlet pipe between the first limiting stand 4 and the second limiting stand 5 is interference fitted with the inserting paragraph, its magnitude of interference
For 0.5mm, to ensure that air inlet pipe and inserting paragraph are completely embedded, gap is not produced therebetween.
In order to improve in the air inflow in the unit interval, the present embodiment, the air inlet pipe of turbocharger 1 is along airintake direction
Under the pyramidal structure that the diameter of axle is tapered into, this structure, it is inner because caliber is smaller, and pressure is smaller, so that flow velocity herein
Comparatively fast, the air inflow of unit interval is improved.
First limiting stand 4 is wedge structure of the projection in air inlet tube end, the front end face of the first limiting stand 4 and air inlet
The end face of pipe is concordantly and with the cascaded surface against the rear end face of the first limiting stand 4 is stretched into annular spacing groove 3 and and cascaded surface
The end face of offside against.Be using stepped purpose it is convenient for assembly, because annular spacing groove is opened in the inner side of escape pipe
, thus, if using complete interference fit, assembling effect is poor, and stepped design, its outer end with annular spacing groove
There is gap in face.
A buckling groove 6 is also equipped with outside the air inlet pipe, buckling groove 6 is with annular spacing groove 3 in the axial direction of escape pipe 2
It is adjacent, clip 7 is fixed with the buckling groove, by locked clip device, further the junction of escape pipe and connecting tube is fixed.
Manufacture processing for convenience, the escape pipe 2 is made up of injection moulding integrated molding.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims.
