Abstract
The utility model is applied in automobile hydraulic tubular union field, refer more particularly to the male connection for hydraulic tube, it comprises screw thread leading portion, hexagonal intermediate section and screw thread rear end, male connection inside has axial hole, described screw thread leading portion has the first plane of inclination, the second plane of inclination and horizontal transition section, horizontal transition section is located between two plane of inclination, and the horizontal sextant angle of first, second plane of inclination is 45 °, the height of the first plane of inclination is 0.6-0.7mm, and the height of the second plane of inclination is 0.2-0.3mm.By implementing the utility model, mainly solve male connection poor sealing performance in prior art, complexity is installed, the technical problem that cost is high.
Description
Technical field
The utility model is applied to, in automobile hydraulic tubular union field, refer more particularly to the male connection for hydraulic tube.
Background technique
Inipple, refers to threaded pipe joint, is modal a kind of pipe fitting in industry and life, according to actual needs, can change the shape of inipple, then pass through at the two ends of inipple connecting tube, thereby obtain our required pipeline path.So, inipple makes being connected between pipeline and pipeline become simpler, and dismounting and change is also easier, has greatly saved the cost that pipeline connects.Male connection is connecting pipeline or pipeline is contained in to the part on hydraulic element in hydraulic system, inipple of the prior art, its two ends are suitable for connecting other parts or other pipeline in fluid system, its two ends are for having externally threaded linkage section, middle for profile is the intermediate section of outer-hexagonal shape, spanner can be installed inipple in the intermediate section application of force.But there is following shortcoming in the inipple of this structure: because one of them linkage section of inipple is used for connecting tube, joint external application cutting ferrule tightens up, and pipeline end face is planar end surface, therefore, in order to guarantee sealability, must between pipeline and inipple, end-face seal ring be set, like this, one side complex structure, part is many, complexity is installed, reduces manufacturing efficiency; On the other hand, the poor sealing performance of high, the end face seal of cost.
Model utility content
The utility model mainly solves male connection poor sealing performance in prior art, complexity is installed, the technical problem that cost is high.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: for the male connection of hydraulic tube, comprise screw thread leading portion, hexagonal intermediate section and screw thread rear end, male connection inside has axial hole, described screw thread leading portion has the first plane of inclination, the second plane of inclination and horizontal transition section, horizontal transition section is located between two plane of inclination, and the horizontal sextant angle of first, second plane of inclination is 45 °, the height of the first plane of inclination is 0.6-0.7mm, and the height of the second plane of inclination is 0.2-0.3mm.
Adopt technique scheme, the utility model compared with prior art has the following advantages: because the joint of external pipeline and inipple has adopted the sealing configuration of twice inclined-plane sealing, liquid in hydraulic tube can not exosmosed, therefore, saved on the one hand seal ring, simple in structure, easy to assembly, greatly enhance productivity; Also reduced on the other hand cost of production.
Further, before described screw thread, segment length is 15-16.5mm, and diameter is 9.5-10.5mm.
Further, in the middle of described hexagonal, segment length is 7.9-8.7mm.
Further, described screw thread rear end is long is 19.5-20mm, and diameter is 13.5-13.7mm.
Further, the diameter of described axial hole is 6.8-7.0mm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is right elevation of the present utility model.
Embodiment
As shown in Figure 1, the technical program provides a kind of male connection for hydraulic tube, comprises screw thread leading portion 1, hexagonal intermediate section 2 and screw thread rear end 3, and male connection inside has axial hole 7, and its diameter is 6.8-7.0mm.Described screw thread leading portion 1 is long is 15-16.5mm, and diameter is 9.5-10.5mm, and hexagonal intermediate section 2 is long is 7.9-8.7mm, and screw thread rear end 3 is long is 19.5-20mm, and diameter is 13.5-13.7mm.Described screw thread leading portion 1 has the first plane of inclination 4, the second plane of inclination 6 and horizontal transition section 5, horizontal transition section 5 is located between two plane of inclination, and the horizontal sextant angle of first, second plane of inclination is 45 °, the height of the first plane of inclination 4 is 0.6-0.7mm, and the height of the second plane of inclination 6 is 0.2-0.3mm.
In the technical program, because the horizontal sextant angle of first, second plane of inclination is 45 °, when external pipeline is connected with inipple, barrier effect is played in plane of inclination, when making liquid mobile in pipeline, can from the gap of pipeline and inipple joint, not infiltrate, and the sealing configuration that has adopted twice inclined-plane sealing herein, has ensured the sealing between male connection and pipeline more.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (5)
1. for the male connection of hydraulic tube, comprise screw thread leading portion, hexagonal intermediate section and screw thread rear end, male connection inside has axial hole, it is characterized in that, described screw thread leading portion has the first plane of inclination, the second plane of inclination and horizontal transition section, and horizontal transition section is located between two plane of inclination, and the horizontal sextant angle of first, second plane of inclination is 45 °, the height of the first plane of inclination is 0.6-0.7mm, and the height of the second plane of inclination is 0.2-0.3mm.
