As further improvement, the main part of described Joining clasp is provided with two annular recess structures that cooperate with the ring-type arcuate configuration of described front and rear tube.
As further improvement, the ring-type arcuate configuration of the ring-type arcuate configuration of described preceding pipe and back pipe is superimposed.
As further improvement, the main part of described Joining clasp is provided with an annular recess structure that the ring-type arcuate configuration that is superimposed of described front and rear tube is cooperated.
As further improvement, between the described front pipe afterbody outside and the anterior inboard of described rear pipe, be formed with cavity, in described cavity, be provided with a sealing ring.
As further improvement, the nose end of described rear pipe front portion circumferentially offers at least one otch.
As further improvement, described Joining clasp is a metal material, and tightens pipe before described and back pipe lock ring by the bolt of snap ring.
The utlity model has following advantage:
Blast duct for vehicle of the present utility model, Guan Yuhou managed mutually sheathed mode before its syndeton adopted blast pipe, and be provided with annular arcuate configuration at front Guan Yuhou pipe, by Joining clasp and the annular recess structure that matches with aforesaid annular arcuate configuration that is arranged on the Joining clasp, this Joining clasp can guarantee described front and rear tube is coated the stability that lock ring links together effectively; Simultaneously, be provided with a sealing ring in the cavity that between the described front pipe afterbody outside and the anterior inboard of described rear pipe, forms, and the effect of the otch of the rear pipe of utilization, make front and rear tube and sealing ring each other gap under the effect of the clamping force of metal clasp more and more littler, and then play good sealing function; The syndeton of above-mentioned blast pipe, not only simple in structure, can also save gas and protect welding, with the multiple working procedure of blast pipe front and rear tube and flange welding, greatly improved blast pipe and produced efficiency of assembling.

[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, first embodiment of the present utility model: a kind of blast duct for vehicle, pipe 1 and back pipe 2 before comprising, the afterbody 10 of pipe 1 is provided with a ring-type arcuate configuration 11 before described, the front portion 20 of described back pipe 2 also is provided with a ring-type arcuate configuration 21, and the external diameter of described preceding pipe 1 afterbody 10 is less than the internal diameter of pipe 2 front portions 20, described back, and along the flow direction of tail gas rafting air-flow, described preceding pipe 1 afterbody 10 is sheathed on the inboard of pipe 2 front portions 20, back.And please in the lump with reference to figure 2 and Fig. 4, wherein, this syndeton also comprises Joining clasp 4, and described Joining clasp 4 is metal material, and its main part is provided with two annular recess structures 41 that cooperate with the ring-type arcuate configuration (11,21) of described front pipe 1 and rear pipe 2.This metal clasp 4 coats described front pipe 1 and rear pipe 2, and tightens described front pipe 1 and rear pipe 2 lock rings by bolt 6 and the nut 5 of this metal clasp 41, the front pipe 1 that can effectively guarantee blast pipe be connected the stability that pipe 2 connects.
