The utility model is applied to, in automobile hydraulic tubular union field, refer more particularly to the female adapter for hydraulic tube.It comprises screw thread leading portion, hexagonal intermediate section and screw thread rear end, female adapter inside has axial hole, before described screw thread, intersegmental part has the first horn mouth and second horn mouth of outward opening, between two horn mouths, be provided with horizontal transition face, the first horn mouth and the second bell-mouthed horizontal sextant angle are 120 °, the first bell-mouthed inclined-plane height is 1.1-1.3mm, and the first bell-mouthed inclined-plane height is 1.9-2.1mm.By implementing the utility model, mainly solve female adapter 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 female adapter 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.Female adapter 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 the female linkage section of tool, 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 female adapter 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 female adapter of hydraulic tube, comprise screw thread leading portion, hexagonal intermediate section and screw thread rear end, female adapter inside has axial hole, before described screw thread, intersegmental part has the first horn mouth and second horn mouth of outward opening, between two horn mouths, be provided with horizontal transition face, the first horn mouth and the second bell-mouthed horizontal sextant angle are 120 °, the first bell-mouthed inclined-plane height is 1.1-1.3mm, and the first bell-mouthed inclined-plane height is 1.9-2.1mm.
Adopt technique scheme, the utility model compared with prior art has the following advantages: because intersegmental part before screw thread has the first horn mouth and second horn mouth of outward opening, the first horn mouth and the second bell-mouthed horizontal sextant angle are 120 °, when the interior pipeline connecing is connected with inipple, barrier effect is played in bell-mouthed plane of inclination, when making liquid mobile in pipeline, can from the gap of pipeline and inipple joint, not infiltrate, and adopted the sealing configuration of two horn mouth inclined-plane sealings herein, more ensured the sealing between female adapter and pipeline.Therefore, saved seal ring on the one hand, simple in structure, easy to assembly, greatly enhance productivity; Also reduced on the other hand cost of production.
Further, the length of described horizontal transition face is 8.1-8.4mm.
Further, before described screw thread, segment length is 10.3-10.7mm, and diameter is 13.75-14.1mm.
Further, the diagonal distance of described hexagonal intermediate section is 15.9-16.2mm, and opposite side distance is from being 13.74-14.1mm.
Further, the length of described screw thread back segment is 20.79-21.1mm, and diameter is 13.75-14.1mm.
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 Fig. 1, shown in 2, the technical program provides a kind of female adapter for hydraulic tube, comprise screw thread leading portion 1, hexagonal intermediate section 2 and screw thread rear end 3, female adapter inside has axial hole 7, described screw thread leading portion 1 is long is 10.3-10.7mm, diameter is 13.75-14.1mm, the diagonal distance of hexagonal intermediate section 2 is 15.9-16.2mm, opposite side distance is from being 13.74-14.1mm, the length of described screw thread back segment 3 is 20.79-21.1mm, diameter is 13.75-14.1mm, described screw thread leading portion 1 inside has the first horn mouth 4 and second horn mouth 6 of outward opening, between two horn mouths, be provided with horizontal transition face 5, the horizontal sextant angle of the first horn mouth 4 and the second horn mouth 6 is 120 °, the inclined-plane height of the first horn mouth 4 is 1.1-1.3mm, the inclined-plane height of the first horn mouth 6 is 1.9-2.1mm.
In the technical program, because intersegmental part before screw thread has the first horn mouth 4 and second horn mouth 6 of outward opening, the horizontal sextant angle of the first horn mouth 4 and the second horn mouth 6 is 120 °, when the interior pipeline connecing is connected with inipple, barrier effect is played in bell-mouthed 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 two horn mouth inclined-plane sealings herein, has ensured the sealing between female adapter 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.
