Description
Technical field
The utility model relates to automobile exhaust pipe field, particularly a kind of double-exhaust decorative tail tube.
Background technique
As everyone knows, outlet pipe is the vitals for car exhaust gas, generally comprises outlet pipe main body, exhaust connection and decoration tail tail pipe.Because decorative tail tube is what expose, good exhaust performance should be played, also want beautiful shape simultaneously, meet certain decoration demand.Existing most decorative tail tube is generally monomer-type, and for automobile or the sport car of some huge discharge, its fuel consumption and air displacement are all relatively large, and monomer-type decorative tail tube is difficult to meet its needs, easily causes the problems such as exhaust is slow, heat dispersion is poor.Also there are some double-exhaust decorative tail tubes market, but is generally and is connected by exhaust connection after two decorative tail tubes are independently arranged again, and not only strengthen cost of production, and assembling is wasted time and energy.The patent No. be 201320446092.7 utility model patent provide a kind of two inner bags decoration tailpipes of integral type, but problem is, there are some zig zag planes and arc surface in the surface of the inner bag of this tailpipe, the area of contact of the face of weld between upper and lower inner bag and shell is less, not easily locate, be easy between shell and inner bag the phenomenon such as rosin joint, sealing-off occurs, defect rate is higher.And due to inner bag be bending setting, have a lot of zig zag plane and arc surface, moisture can not be discharged smoothly, accumulate over a long period and can accumulate large quantity of moisture in outlet pipe, freeze blocking outlet pipe, causes waste gas to be arranged and do not go out, new gas does not enter cylinder, thus causes engine start difficulty.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of and can position the welding position between shell and inner bag easily, welding effect is good, effectively can prevent the double-exhaust decorative tail tube of freezed in winter.
The technical scheme in the invention for solving the above technical problem is: a kind of double-exhaust decorative tail tube, comprise shell and the inner bag being provided with double air cavity, a upper ancient piece of jade, round, flat and with a hole in its centre for described shell and the corresponding double air cavity place of lower wall are equipped with the depressed part be inwardly recessed, the end face of described depressed part is a plane, the position of the described depressed part described in inner bag correspondence is provided with projection, the upper surface of described projection is the plane matched with the end face of described depressed part, and the depressed part place of described shell offers strip hole, and described shell to be matched with the end face of the projection of described inner bag by described depressed part and is welded as a whole, the front-end edge place of described inner bag is provided with the flanging of bell mouth shape, and the front end of described shell is by inwardly the straight flange of setting and the flanging of described inner bag offset, be provided with heating equipment between the outer wall of described inner bag and the inwall of described shell, described heating equipment is by power supply and be connected with described power electric and the electric heating film be located on described inner bladder outer wall forms.
Compared with prior art, the utility model has the advantage of: a upper ancient piece of jade, round, flat and with a hole in its centre for the shell of this double-exhaust decorative tail tube and the corresponding double air cavity place of lower wall are equipped with the depressed part be inwardly recessed, the end face of depressed part is a plane, the position of the depressed part described in inner bag correspondence is provided with projection, the upper surface of projection is the plane matched with the end face of depressed part, and the depressed part place of shell offers strip hole, and shell to be matched with the end face of the projection of upper inner-liner by depressed part and is welded as a whole.Like this, not only effectively can position welding part, determine welding surface of contact, and the depressed part place of shell offers strip hole, welding operation is more convenient, can effectively avoid the phenomenon such as rosin joint, sealing-off occurs between shell and inner bag.The front-end edge place of inner bag is provided with the flanging of bell mouth shape, and the front end of shell is by inwardly the straight flange of setting and the flanging of inner bag offset.Like this, the flanging of inner bag can form effective support to the straight flange of the front end of shell, and structure is more firm, profile is also more attractive in appearance.Be provided with heating equipment between the outer wall of inner bag and the inwall of shell, heating equipment is by power supply and be connected with described power electric and the electric heating film be located on inner bladder outer wall forms.Like this, by the heating of electric heating film to inner bag, effective making ice blocking outlet pipe.
As preferably, described inner bag is welded to form by limit integral type more than being circumferentially provided with by upper inner-liner and bottom inner container.Like this, the shaping and assembling of inner bag is all more convenient.
As preferably, the front-end edge of described shell is a hypotenuse.Like this, the outward appearance of this outlet pipe is more attractive in appearance.
As preferably, between the outer wall of described inner bag and the inwall of described shell, be also provided with thermal insulation layer.Like this, better heat preservation, can effective making ice.
As preferably, described thermal insulation layer is made up of glass wool material.Like this, this thermal insulation layer also has certain erasure effect.
