Embodiment

To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing And specific embodiment is described in detail.

As shown in Figures 1 to 4, the utility model embodiment provides a kind of automobile pipeline fixing device, applied to automobile, institute Stating automobile includes fuel pipe, including：

Fixed support 1 and instlated tubular 2；Wherein, the first end of the fixed support 1 is fixed on the vehicle body of the automobile, Support bracket fastened second end is socketed in the outer surface of instlated tubular 2, and the instlated tubular 2 is hollow structure, the fuel pipe The hollow part of the instlated tubular 2 is arranged in, there is space between the instlated tubular 2 and the fuel pipe.

In the utility model embodiment, due to the presence of oil pump, pulsation is usually there will be in fuel pipe, is produced by pulsation Vibration vehicle body, therefore the first of the fixed support 1 can be delivered to by the fixed support 1 of the automobile pipeline fixing device End can be fixed by way of welding with vehicle body, can so ensure the intensity of the fixed support 1 and vehicle body junction, make Obtain junction to be not easy to be broken or destroyed because of vibration, certain fixed support 1 can also pass through other connected modes It is fixed with the vehicle body, welding is that one kind preferably selects for intensity.In addition, the material of the fixed support 1 can Think metal or rubber, its intensity can be improved using metal, the transmission of vibration can be reduced using rubber.

In addition, the material of the instlated tubular 2 can be heat resistance and the high material of heat reflectivity, for example, silver, nickel, aluminium foil or Plate polyester or steel plate of metal etc..

So, using the good heat resistance of the instlated tubular 2 and heat reflectivity the characteristics of, can be by outside the instlated tubular 2 Portion's heat as caused by the thermals source such as blast pipe is effectively completely cut off, so as to improve the effect of heat insulation of vehicle fuel pipe.

Optionally, the material of the instlated tubular is aludip；It should be noted that aludip has good anti-height Warm oxidisability, can be long-term use of and non-discolouring at 450 DEG C, and maximum operation (service) temperature is up to 750 DEG C；Specifically, it can be aluminium Content 90%, the alloy layer steel plate of silicone content 10%.So, using its good high temperature oxidation resistance and heat reflectivity, The transmission of heat can preferably be blocked.

Optionally, as shown in Figure 1 to Figure 2, described device also includes vibration isolation block 3；The vibration isolation block is filled with described In space between instlated tubular 2 and the fuel pipe；It should be noted that due to the presence of oil pump, would generally in fuel pipe In the presence of pulsation, and vibration caused by pulsing can be delivered to vehicle body by the automobile pipeline fixing device, design the vibration isolation block 3 Purpose be exactly to be to reduce the vibration that the automobile pipeline fixing device is delivered to vehicle body.Wherein, the material of the vibration isolation block 3 It can be rubber or plastics, preferably rubber, can possess higher shock attenuation result using the high-damping of rubber；So, it is sharp The vibration that the automobile pipeline fixing device is delivered to vehicle body is effectively reduced with the vibration isolation block 3 that material is rubber.

Optionally, as shown in Figure 1 to Figure 2, described device also includes inner tube 4；Said inner tube 4 is arranged at the instlated tubular 2 In space between the fuel pipe, said inner tube 4 is hollow structure, and is socketed in the outer surface of the fuel pipe；

There is space, the vibration isolation block 3 is filled with said inner tube 4 and institute between said inner tube 4 and the instlated tubular 2 State in the space between instlated tubular 2.

Wherein, the material of said inner tube 4 can be plastics, and its diameter of section can determine according to tubing diameter, so that The fuel pipe can be passed through and is defined, and it is excellent that the gap between the fuel pipe and said inner tube 4, which is no more than 1mm,.So, contrast Directly it is joined directly together in by the vibration isolation block 3 with the fuel pipe, can only be directly from combustion when the vibration isolation block 3 is damaged Dismantled on oil pipe, so as to which maintenance cost is higher；And embodiment provided by the utility model is utilized, can be directly by described in Inner tube 4 is withdrawn from outside the fuel pipe, so as to improve removal efficiency and reduce maintenance cost.In addition, utilize plastics Material can lift the shock attenuation result of the automobile pipeline fixing device.

Optionally, as shown in Figure 1 to Figure 2, described device includes multiple vibration isolation blocks 3；Wherein, in the multiple vibration isolation block 3 Each vibration isolation block 3 between there is gap 5；It should be noted that the cross sectional shape in the gap 5 can be trapezoidal shape；Set The purpose in gap 5 be in order to reduce the contact area of the vibration isolation block 3 and the instlated tubular 2 and said inner tube 4, it is so effective Reduce the instlated tubular 2 and be delivered to the heat of inner tube 4, and vibration isolation and heat-insulated effect can be provided simultaneously with.

Optionally, as shown in Figure 1 to Figure 2, described device includes at least four vibration isolation block 3；This is from effect of heat insulation and vibration isolation One kind for effect considers more preferably is selected.

Optionally, the material of the vibration isolation block is rubber, because the vibrational energy of the fuel pipe in itself is relatively low, therefore institute The rigidity for stating rubber acts on than relatively low competence exertion, it is preferred that the rubber can be the rubber that shore hardness is 50, so Vibration can preferably be absorbed.

Optionally, through hole 11 is provided with the support bracket fastened first end as shown in Figure 1, the through hole 11 is mainly used in Coordinate with bolt so that the fixed support 1 is fixed on vehicle body, so can conveniently dismantle.
