Abstract
The utility model relates to an exhaust conduit of silencer jet exhaust for car. The structure is characterized in that the utility model is composed of an inner sleeve tube connected with the tail gas tube of vehicle silencer and an outer sleeve tube which can move in the axial direction relatively to the inner sleeve tube. The tail gas of the automobile engine can be discharged from the backside of the car body to prevent the tail gas from sooting the back bumper; when the exhaust conduit of silencer jet exhaust for car receives the impact from the back vehicle, the exhaust conduit of silencer jet exhaust for car automatically contracts to avoid bringing about the damage of the starting exhaust manifold. The application of exhaust conduit of silencer jet exhaust for car can keep small-sized cars clean and beautiful particularly.
Description
The utility model relates to a kind of exhaust manifolds of automotive muffler offgas duct.
The rear port of the existing automotive muffler offgas duct that is positioned at automobile bottom is generally apart from about 5～10 centimeters of automobile rear bumper (causing the damage of enmgine exhaust to prevent to be collided), when waste gas is discharged, tend to the rear bumper sooting, so not only influenced the outward appearance of vehicle, and stain is difficult to clean.
The purpose of this utility model is the exhaust manifolds that a kind of automotive muffler offgas duct will be provided.When it is socketed on the rear portion of automotive muffler offgas duct, the waste gas that not only helps motor car engine is discharged from rear vehicle, thereby prevents waste gas sooting rear bumper, and when it is subjected to collision from front vehicle, can shrink automatically, thereby avoid causing the damage of starting gas exhaust manifold.
The utility model by with the joining inner sleeve of automotive muffler offgas duct and can forming by the axially movable outer sleeve of relative inner sleeve.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model working state schematic representation.1 is car body among the figure; 2 is rear bumper; 3 is inner sleeve; 4 is outer sleeve; 5 is silencing apparatus.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
With reference to accompanying drawing, the utility model by inner sleeve 3 with can form by the axially movable outer sleeve 4 of relative inner sleeve.The front end of inner sleeve is provided with fastening garter spring 7 and the bolt assembly 15(of two ends 16 locking of fastening garter spring is made of bolt and nut), the inner sleeve underside of forward is provided with sealing 6, the rear portion of inner sleeve is provided with several positioning grooves 8 that encloses rich its periphery wall, inner sleeve rear end outer rim is provided with baffle ring 9, being provided with some between inner sleeve rear portion outer wall and the outer sleeve inner wall, to be undulatory its effect of leaf spring 10(be that the relative inner sleeve of avoiding being supported of outer sleeve rocks) and a location catch spring 11.One end 12 of leaf spring is fixed on the outer wall of inner sleeve.The front end of location catch spring 13 is fixed in outer sleeve inner wall, and rearward end has the emulsus protuberance 14 that snaps in positioning groove.
The rear end of outer sleeve is provided with aduncate edge 17, to prevent that oily water influences outward appearance from this place's outflow in the waste gas.
Of the present utility model to install and use procedure declaration as follows: fastening garter spring is locked by bolt assembly in the rear portion that 1) inner sleeve 3 is enclosed within the automotive muffler offgas duct; 2) the outer sleeve post-tensioning is contacted baffle ring 9 until the rear end of location catch spring; 3) waste gas when motor passes through these exhaust manifolds through silencing apparatus, waste gas is just discharged from rear vehicle on the one hand, thereby avoids waste gas sooting rear bumper, on the other hand, be deposited on the greasy dirt in the exhaust manifolds, just flow out from the front port of outer sleeve or the sealing of inner sleeve; 4) when the collision that is subjected to from front vehicle, the outer sleeve reach, the emulsus protuberance 14 of location catch spring slips in the positioning groove of inner sleeve front side, the exhaust manifolds of automotive muffler offgas duct is shunk, thereby avoid causing the damage of starting gas exhaust manifold.
The utility model simple structure, easy to use, good economy performance.Its application is particularly conducive to the cleaning that keeps pony car and attractive in appearance.
