Abstract

The utility model discloses an exhaust tail pipe with a carbon fiber outer sleeve. The exhaust tail pipe with the carbon fiber outer sleeve is composed of an inner pipe and the carbon fiber outer sleeve, wherein the carbon fiber outer sleeve is sleeved outside the inner pipe, the carbon fiber outer sleeve is a hollow pipe body, and an end edge of the tail end is bent inwards and extends to form an inner lip portion. By means of the structure, the exhaust tail pipe is enabled to be light, and the end edge of the carbon fiber outer sleeve is prevented from hurting people.

Description

Tailpipe with carbon fiber jacket pipe

Technical field

The utility model relates to a kind of tailpipe, particularly a kind of tailpipe with carbon fiber jacket pipe, and its safety, lightweight can effectively prevent the ora terminalis incised wound people of carbon fiber jacket pipe.

Background technique

See also Fig. 1, shown in Figure 2, it is an existing tailpipe 1 with carbon fiber jacket pipe 12, wherein be provided with an inner tube 11 in the carbon fiber jacket pipe 12 of this tailpipe 1, and the tail end ora terminalis 121 of this carbon fiber jacket pipe 12 directly cuts with the mould cutter and forms, 1 group of this tailpipe is established and is connect the tail end of holding in the mouth in automobile exhaust pipe, and slightly protrude from outside car body, therefore after automobile parking, because the tail end ora terminalis 121 of this carbon fiber jacket pipe 12 is very sharp-pointed, when the pedestrian close because of carelessness, slightly careless just being easy to by its incised wound, and be that This is what people generally disapprove of; But except the aesthetic feeling with high-quality, light weight own can not increase the loading of outlet pipe due to this carbon fiber jacket pipe 12, liked by Ai Che family, right this be fraught with risks and the contradiction of very attractive under, perplexing Ai Che family always.

The model utility content

In view of this, inventor of the present utility model is for the existing disappearance of depositing, after going through research improvement many times, finally complete the utility model, it is the purpose of this utility model, be to provide a kind of safe, light-weighted tailpipe, the structure spy can make the tailpipe lightweight whereby, and can prevent the ora terminalis incised wound people of carbon fiber jacket pipe.

For reaching above-mentioned the purpose of this utility model, a kind of tailpipe with carbon fiber jacket pipe of the utility model is comprised of the outside sheathed carbon fiber jacket pipe of an inner tube, wherein:

This inner tube, its body has an inner via hole, and this body peripheral envelope is provided with a supporting frame, and this supporting frame is provided with at least one supporting base, has one first fixed hole on this supporting base;

This carbon fiber jacket pipe, it is by the made body of a carbon fiber, it has a hollow via-hole, this carbon fiber jacket pipe periphery is provided with at least one the second fixed hole, this second fixed hole is corresponding with this first fixed hole, penetrate for a binding member fixed, this carbon fiber jacket pipe support is established and to be fixed in this inner tube outside;

Wherein, the tail end ora terminalis of this carbon fiber jacket pipe is stretched an epipharynx section to curls inward, so that this tail end ora terminalis forms a circular arc ora terminalis, can prevent thus this carbon fiber jacket pipe tail end ora terminalis incised wound people.

Described tailpipe with carbon fiber jacket pipe, wherein, this inner tube body front end is provided with a caliber less than the front cervical part of esophagus of this pipe diameter, the fixed fixed base of this front cervical part of esophagus periphery.

Described tailpipe with carbon fiber jacket pipe, wherein, this fixed base is provided with a locking holes, and this locking holes is locked for a locking element.

Described tailpipe with carbon fiber jacket pipe, wherein, this foreneck intersegmental part more is arranged with a flexible fastening cover, and this flexible fastening cover is an annular body.

The beneficial effects of the utility model are to provide a kind of safe, light-weighted tailpipe, and the structure spy can make the tailpipe lightweight whereby, and can prevent the ora terminalis incised wound people of carbon fiber jacket pipe.

Embodiment

See also Fig. 3, Fig. 4, shown in Figure 5, a kind of tailpipe A with carbon fiber jacket pipe of the utility model, this tailpipe A is comprised of an outside sheathed carbon fiber jacket pipe 3 of inner tube 2, wherein:

This inner tube 2, its body 22 has an inner via hole 20, these body 22 front ends are provided with a caliber less than the front cervical part of esophagus 21 of these body 22 diameters, the fixed fixed base 23 of cervical part of esophagus 21 peripheries before being somebody's turn to do, this fixed base 23 is provided with a locking holes 231, this locking holes 231 is locked for a locking element 232, this tailpipe A is consolidated in this outlet pipe 5 of an outlet pipe 5(as existing member), these body 22 peripheral envelope are provided with a supporting frame 24, this supporting frame 24 is provided with at least one supporting base 241, has one first fixed hole 242 on this supporting base 241;

This carbon fiber jacket pipe 3, it is by the made body of a carbon fiber, it has a hollow via-hole 30, these carbon fiber jacket pipe 3 peripheries are provided with at least one the second fixed hole 32, this second fixed hole 32 is corresponding with this first fixed hole 242, penetrate for a binding member B fixed, this carbon fiber jacket pipe 3 is set up and is fixed in this inner tube 2 outsides;

It is characterized in that:

The tail end ora terminalis 31 of this carbon fiber jacket pipe 3 is stretched an epipharynx section 311 to curls inward, so that this tail end ora terminalis 31 forms a circular arc ora terminalis, can prevent thus this carbon fiber jacket pipe 3 tail end ora terminalis 31 incised wound people's (seeing also shown in Figure 6).
