Abstract

The utility model relates to a high pressure oil pipeline structure for the diverter, which belongs to the automotive vehicle hydraulic pressure boosting type diverter. The high pressure oil pipeline structure comprises a high pressure rubber pipe and high pressure metal pipes arranged at both ends of the high pressure rubber pipe, and one end of the high pressure rubber pipe is connected with the high pressure metal pipes through compression joint. The high pressure oil pipeline structure is characterized in that the other end of the high pressure rubber pipe is connected with the pipe orifice end of one pipe joint through compression joint, the thread end of the pipe joint is attached with the pipe orifices of the high pressure metal pipes through a conical surface and is fastened through bolts. The high pressure oil pipeline structure solves the problem that because the high pressure rubber pipe and the high pressure metal pipes arranged at both ends of the high pressure rubber pipe are connected through compression joint, the contortion of the high pressure rubber pipe is caused after the assembly, therefore to cause the untimely fatigue failure, the fixed connection and sealing of the high pressure oil pipeline structure is reliable, the direction of the high pressure metal pipe is not required to be controlled during the assembly, the corresponding tools are not required to be configured, thereby enhancing the working efficiency and reducing the production cost.

Description

Commutator high-pressure oil pipe pipeline structure

Technical field

The utility model relates to the commutator of hydraulic pressure of motor vehicle assistance type, the structure of high-pressure oil pipe pipeline especially wherein.

Background technique

High-pressure oil pipe pipeline in the commutator of hydraulic pressure of motor vehicle assistance type comprises one section high-pressure rubber pipe and is connected in its two ends to have the high-pressure metal pipe of specific tube road curve separately.In the prior art, be the two ends that earlier two high-pressure metal pipes are crimped on described high-pressure rubber pipe, make the three connect firmly into an integral body, the high-pressure metal pipe with two ends is connected to commutator filler opening and oil pump oil outlet respectively again.Because the location error assembling back high-pressure rubber pipe is distorted, and the crooked high-pressure metal pipe at its two ends is subjected to the restriction of this spatial position, place, can not do corresponding rotation to be adjusted, so the distortion of high-pressure rubber pipe can not obtain removing.Under high pressure conditions, the easy premature fatigue of high-pressure rubber pipe that is in twisted state lost efficacy, and broke then, and the hydraulic booster effect is disappeared.

Summary of the invention

The purpose of this utility model provides a kind of commutator high-pressure oil pipe pipeline structure, breaks with distortion so that the premature failure of avoiding high-pressure rubber pipe, prolongs the working life of high-pressure oil pipe.

The commutator high-pressure oil pipe pipeline structure that the utility model provides, the high-pressure metal pipe that comprises high-pressure rubber pipe and its two ends, one end of high-pressure rubber pipe and a high-pressure metal pipe crimping mutually, it is characterized in that, the nose end crimping mutually of the other end of high-pressure rubber pipe and a pipe joint, the threaded end of pipe joint and another high-pressure metal pipe mouth of pipe are fitted with the conical surface, are tightened up by nut.

During assembling, the first step is crimped on the two ends of high-pressure rubber pipe respectively with the pipe joint of a high-pressure metal pipe and the band conical surface, becomes one section pipeline; Second goes on foot nut sleeve at another high-pressure metal pipe epicone facial canal oral area; The 3rd step was connected to commutator filler opening and oil pump oil outlet respectively with two high-pressure metal pipes; The 4th step was fitted the conical surface of two sections pipes, and nut is screwed on the pipe joint screw thread until limit place, promptly formed between these two sections pipes to compress the deformation type sealing.

The beneficial effects of the utility model are:

1, high-pressure rubber pipe only has an end to run affairs with rotatable high-pressure metal to connect firmly earlier, the other end connect firmly final tache in assembling, and to be the conical surface contact the conical surface in this connection place, do not have the orientation requirement, like this distortion with regard to not producing sebific duct.

2, thereby connecting firmly at last of high-pressure rubber pipe and high-pressure metal pipe takes to advance the means make tube wall deformation compress sealing by pipe joint with conical surface applying nut, easy operation, and it is reliable to connect firmly sealing effect.

3, because technology is become separately assembling of high-pressure oil pipe, dock, the orientation when need not to control the assembling of high-pressure metal pipe has again improved working efficiency, has also saved simultaneously to be the frock that the control azimuth disposed, and cost of production is reduced again.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, the utility model comprises that its high-pressure rubber pipe 1 that sleeve pipe 7 is arranged and its two ends respectively have the high-pressure metal pipe 2 and the high-pressure metal pipe 3 of certain bend outward, between high-pressure rubber pipe 1 and the high-pressure metal pipe 3 by pipe box 4 crimping mutually, become one, connecting between high-pressure rubber pipe 1 and the high-pressure metal pipe 2 referring to Fig. 2, high-pressure rubber pipe 1 is by pipe joint 5, nut 6 links with high-pressure metal pipe 2, pipe joint 5 is basic identical with general pipe joint, just be provided with male cone (strobilus masculinus) 2a (see figure 3) at its threaded end end face, change to high-pressure metal pipe 2 is at the one end horn mouth to be set, has the inner conical surface 5a (see figure 4) that matches with pipe joint 5 male cone (strobilus masculinus) 2a on the horn mouth, purpose is that high-pressure metal pipe 2 and pipe joint 5 are fitted with the conical surface, and make the mouth of pipe of high-pressure metal pipe 1 be pressed to and to be wrapped on the pipe joint 5 by nut 6, reliable to reach sealing, nut 6 one ends are provided with aperture, it is enclosed within on the tube wall of high-pressure metal pipe 1 with aperture, can move axially thereon, the surface slope of nut aperture and screw transition position should be identical with described bell-mouthed surface slope, in order to good fit, before the high-pressure oil pipe butt joint, the nose end of pipe joint 5 passes through pipe box 4 crimping mutually with the unassembled end of high-pressure rubber pipe 1, become one, during butt joint two sections pipes are fitted in described conical surface place, the nut 6 that is enclosed within advance on the high-pressure metal pipe 2 is tightened on the screw thread of pipe joint 5, the horn mouth of high-pressure metal pipe 2 is just compacted and wrap the threaded end of being strict in pipe joint 5, has realized connecting firmly and sealing of high-pressure rubber pipe 1 and high-pressure metal pipe 2.
