Abstract
The invention belongs to the field of auto oil pipe fixing devices, and particularly relates to an auto oil pipe positioning mechanism which comprises an oil filling pipe, a carbon tank breather pipe and an oil filling breather pipe, wherein the oil filling pipe is communicated with the oil filling breather pipe, a positioning fixed part is arranged at the end part of the oil filling pipe, the carbon tank breather pipe is fixed on the side surface of the oil filling breather pipe through a connecting piece, the connecting piece comprises a dust cap and a connecting piece, the dust cap is fixed at the end part of the connecting piece, the dust cap covers the pipe orifice of the carbon tank breather pipe, the positioning fixed part is in interference fit with the oil filling pipe and is welded and fixed, and a positioning pin and an arc positioning strip are arranged at the two ends of the positioning fixed part. The auto oil pipe positioning mechanism provided by the invention has the advantages that the positioning is accurate, the fixing and matching effects of the dust cap are excellent, and the positioning accuracy of the oil pipe and the dust preventing effect of the carbon tank breather pipe are improved.
Description
Technical field
The invention belongs to the automobile oil pipe field of fixation devices, specifically a kind of automobile oil pipe location structure.
Background technology
Automobile oil pipe has three kinds basically, and gasoline pipe is to connect petrol feed pump and engine nozzle, is used to provide fuel oil.Also have the power-assisted oil pipe, for steering box provides power-assisted oil, thereby reach the purpose that alleviates cornering resistance.Brake oil pipe is to connect brake pump and brake facing fore-set, and when we stepped on brake, brake pump can be by brake oil pipe to brake facing pressure, two brake facing extruding brake discs, thus reach the purpose that car deceleration stops.
Along with the development people of auto-industry are more and more higher to the requirements such as quality, performance, oil consumption and noise of automobile, be directed to head with the fuel filler pipe of seal ring form, when this fuel filler pipe is installed on automobile because the head is cover of dust, this cover of dust only has dust-proof effect and does not have connection structure, fuel filler pipe one end can't be fixed, when making fuel filler pipe install onboard, eccentric phenomena easily occurs.
Summary of the invention
The present invention is directed to the weak point that exists in above-mentioned technology, propose the automobile oil pipe location structure that a kind of energy simple in structure prevents dust and connects good positioning effect.
The invention provides following technical scheme:
The automobile oil pipe location structure, it comprises fuel filler pipe, canister breather pipe and the breather pipe that refuels, fuel filler pipe and the breather pipe that refuels are communicated with, the fuel filler pipe end is provided with positioning mounting, the canister breather pipe is fixed on the side of oiling breather pipe by attaching parts, connection fixture comprises dust cap and connecting strap, dust cap is fixed on the connecting strap end, dust cap is placed on the mouth of pipe of canister breather pipe, described positioning mounting and fuel filler pipe interference fit and be welded and fixed, positioning mounting two ends are provided with locating dowel pin and arc positioning strip.
The crown face of described dust cap is provided with pit, and cap inwall circumference is provided with projection, and the end face of described canister breather pipe end is provided with fin, and the end face outer peripheral face is provided with groove, and pit coordinates with the fin clamping, and projection coordinates with the groove clamping.
Advantage of the present invention is that accurate positioning and dust cap heavy keying fit are effective, has improved the positional accuracy of oil pipe and the dust-proof effect of canister breather pipe.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A-A to view.
The specific embodiment
as Fig. 1, shown in Figure 2, the automobile oil pipe location structure, it comprises fuel filler pipe 1, canister breather pipe 2 and the breather pipe 3 that refuels, fuel filler pipe 1 and the breather pipe 3 that refuels are communicated with, fuel filler pipe 1 end is provided with positioning mounting 4, canister breather pipe 2 is fixed on the side of oiling breather pipe 3 by attaching parts, connection fixture comprises dust cap 5 and connecting strap 6, dust cap 5 is fixed on connecting strap 6 ends, dust cap 5 is placed on the mouth of pipe of canister breather pipe 2, described positioning mounting 4 is with fuel filler pipe 2 interference fit and be welded and fixed, positioning mounting 4 two ends are provided with locating dowel pin 7 and arc positioning strip 8.
Wherein, the crown face of dust cap is provided with pit, and cap inwall circumference is provided with projection, and the end face of described canister breather pipe end is provided with fin, and the end face outer peripheral face is provided with groove, and pit coordinates with the fin clamping, and projection coordinates with the groove clamping.
