Abstract
The utility model discloses a kind of high-pressure oil pipes of engine anti-leak, have：Oil pipe ontology；End is arranged in oil pipe body end, and end is an integral structure with oil pipe ontology；End is spherical shape；Attaching nut, middle part are equipped with threaded hole；One end of threaded hole is equipped with the beam oral area that diameter reduces, and end is mounted in threaded hole, and end is contacted with beam oral area line, and high-pressure oil pipe is avoided to leak.
Description
Technical field
The utility model belongs to technical field of automobile engine more particularly to a kind of high-pressure oil pipe of engine anti-leak.
Background technique
As the technology of engine increasingly tends to maturing, high-performance, small displacement, environmentally protective miniaturization engine
Become the research direction of each main engine plants at present.
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems：Engine
Fuel pressure is always flowed on high pressure oil rail with by boost in pressure to certain pressure, and through high-pressure oil pipe through high pressure fuel pump.
Be for the design of high-pressure oil pipe wherein it is vital, high-pressure oil pipe once design it is bad once have the risk of certain leakage,
It is even more especially to require especially high, designer end of some main engine plants for high-pressure oil pipe to the design of two ends of high-pressure oil pipe
Head still has the risk of leakage by the way of welding to a certain extent.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of engine anti-leaks for avoiding high-pressure oil pipe from leaking
High-pressure oil pipe.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is：A kind of engine anti-leak
High-pressure oil pipe, which is characterized in that have：
Oil pipe ontology；
End is arranged in the oil pipe body end, and the end is an integral structure with the oil pipe ontology；The end
Head is spherical shape；
Attaching nut, middle part are equipped with threaded hole；One end of the threaded hole is equipped with the beam oral area that diameter reduces, the end
Head is mounted in the threaded hole, and the end is contacted with the beam oral area line.
Oil pipe ontology both ends are respectively provided with an end and attaching nut, and an attaching nut and high pressure oil rail screw thread connect
It connects, another attaching nut is threadedly coupled with high pressure fuel pump.
The diameter of the end maximum is less than the diameter of threaded hole, and the diameter of end maximum is greater than the straight of beam oral area
Diameter.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect, and the end of high-pressure oil pipe is changed
Integrated form, avoids high-pressure oil pipe from leaking.

Label in above-mentioned figure is：1, oil pipe ontology, 11, end, 2, high pressure oil rail, 3, high pressure fuel pump, 4, connection
Nut, 41, beam oral area.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Referring to Fig. 1-3, a kind of high-pressure oil pipe of engine anti-leak, which is characterized in that have：
Oil pipe ontology；
End is arranged in oil pipe body end, and end is an integral structure with oil pipe ontology；End is spherical shape；
Attaching nut, middle part are equipped with threaded hole；One end of threaded hole is equipped with the beam oral area that diameter reduces, and end is mounted on
In threaded hole, end is contacted with beam oral area line.Using line contact form, contact is close, is not likely to produce gap, is not easy to leak.
Oil pipe ontology both ends are respectively provided with an end and attaching nut, and an attaching nut is threadedly coupled with high pressure oil rail,
Another attaching nut is threadedly coupled with high pressure fuel pump.
The diameter of end maximum is less than the diameter of threaded hole, and the diameter of end maximum is greater than the diameter of beam oral area.
After above-mentioned structure, the end of high-pressure oil pipe is changed to integral type form, high-pressure oil pipe is avoided to leak.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
