Abstract

The utility model provides a heat-proof and burn-proof discharge pipe of motor-bicycle for the public of society. The novel style discharge pipe of motor-bicycle is composed of an inner pipe, a metal outer pipe and a quiet device. The front end of the heat-proof inner pipe is connected with a motor of the motor-bicycle, and the rear end of the heat-proof inner pipe directly reaches to a puff port. The heat-proof inner pipe is sleeved by the metal outer pipe. The heat-proof inner pipe is a core body of the metal outer pipe. The shape, structure and the installment portion of the quiet device are the same as the existing quiet device of motor-bicycle and the quiet device is installed at the tail-end of the heat-proof inner pipe. The novel style discharge pipe of motor-bicycle is provided with no high temperature on the surface. The utility model has the advantages that the fabrication cost is low and the utility model is easy to be produced.

Description

The heat insulation anti-scald outlet pipe of motorcycle

The utility model relates to a kind of exhaust system for motorcycle and motorcycle, especially the heat insulation anti-scald outlet pipe of the motorcycle that can avoid the driver to be scalded.

At present, known motorcycle exhaust pipe all is to be made by metallic material, and hot gas that motor produced during motorcycle driving and sound wave are discharged by this metal tube, because the conduction of heat of metal, cause the temperature of outlet pipe very high, cause the thing of scalding the driver to happen occasionally.

The purpose of this utility model provides the heat insulation anti-scald outlet pipe of a kind of motorcycle, its exhaust of not only can eliminating the noise, and also the surface does not have high temperature again.

The purpose of this utility model is achieved in that to adorn in metal outer pipe in the thermostable heat insulation and manages, the front end of pipe has one along peripheral poor toward the garden of turning up in heat insulation, the garden is poor to penetrate the engine exhaust hole and motorcycle engine is joined, the relief opening of the through silencer in its rear end, afterbody have and are drilled with the heat insulation anti-scald circle that hush tube passes through.When motorcycle engine starting exhaust, because the effect of pipe in heat insulation, the air-flow of the high heat of motor does not touch the metal pipe-wall of outlet pipe, thereby high temperataure phenomena does not appear in the outlet pipe surface.

Owing to adopt such scheme, in the motorcycle driving process, the phenomenon that outlet pipe is scalded the driver just can not occur.Simultaneously, the said heat insulation interior tube thickness of the utility model is little, and as core body, the diameter of its metal outer pipe is similar to existing motorcycle exhaust pipe with specification, is easy to produce.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is heat insulation anti-scald first embodiment's of outlet pipe of motorcycle a longitudinal section tectonic maps.

Fig. 2 is the poor tectonic maps in garden of second embodiment's of the utility model heat insulation interior pipe.

Fig. 3 is the 3rd embodiment's of the utility model the screw base of metal outer pipe and the location diagram of outer tube.

Among the figure, 1, heat insulation in the pipe 2, metal outer pipe 3 silencer

4, poor 5, the screw base 6 in garden, heat insulation anti-scald circle

In enforcement shown in Figure 1, the heat insulation anti-scald outlet pipe of motorcycle structure from inside to outside is followed successively by heat insulation interior pipe (1), metal outer pipe (2), the front end of pipe (1) has a garden poor (4) along periphery toward interior cover metal outer pipe (1) front end that turns up in heat insulation, the relief opening of silencer (3) and silencer (3) and metal pipe-wall separated goes directly in its rear end, afterbody has and is drilled with the heat insulation anti-scald circle (6) that hush tube passes through, and garden poor (4) mouth has one can movable screw base (5).

In the embodiment shown in Figure 2, the internal diameter of garden poor (4) is consistent with the external diameter of metal outer pipe (2) front end and can overlap mutually.

In the embodiment shown in fig. 3, the internal diameter of metal outer pipe (2) front end is consistent with the external diameter of the heat insulation interior pipe (1) at poor (4) rear portion, garden and can be inserted in heat insulation interior pipe (1), and screw base (5) can activity.

Claims

1, the heat insulation anti-scald outlet pipe of a kind of motorcycle, comprise heat insulation interior pipe (1), metal outer pipe (2) and silencer (3), it is characterized in that, the front end of said heat insulation interior pipe (1) has one along peripheral be pickled with grains or in wine toward the garden of turning up (4), garden poor (4) penetrates the engine exhaust hole and motorcycle engine is joined, the puff prot of the through silencer in its rear end, afterbody have and are drilled with the heat insulation anti-scald circle (6) that hush tube passes through.

2, according to the heat insulation anti-scald outlet pipe of the said motorcycle of claim 1, it is characterized in that metal outer pipe (2) makes core body with pipe (1) in heat insulation, encase heat insulation interior pipe (1), its front end is inserted in the garden poor (4) of heat insulation interior pipe (1) front end, and in the garden poor (4) muzzle have one can the movable metallic screw seat (5) that is drilled with screw, afterbody has the tinsel that is drilled with the pore that hush tube passes through.

3,, it is characterized in that said heat insulation interior pipe (1), garden poor (4), heat insulation anti-scald circle (6) are to be made by non-brittle high temperature resistant heat insulation material according to claim 1, the heat insulation anti-scald outlet pipe of 2 said motorcycles.
