Summary of the invention
In order to solve the problem, the utility model discloses a kind of oil connection, comprise nut and fittings body, described nut inner hole is provided with internal thread, and one end of described fittings body is connected on the internal thread of described nut, and one end of described fittings body attaching nut is provided with groove, in described groove, Sealing is installed, described nut is connected with transit joint, and described transit joint is provided with annular outside thread, is connected is pressed in described fittings body by described Sealing with the internal thread of described nut.
Further, described fittings body is the axis of guide, and it is sealed department that the described axis of guide connects described nut one end, and described groove is arranged circumferentially on the outer circumferential face of described sealed department.
Further, described fittings body outer wall is provided with the first bulge loop and the second bulge loop, and described first bulge loop is provided with catch, is formed with groove between described first bulge loop and described second bulge loop, described nut is removable to be arranged on described groove, and described catch is connected with the internal thread of described nut.
Further, described Sealing is O shape circle.
Further, described nut is self-locking nut.
Compared with prior art, the utility model has the following advantages:
The utility model by arranging groove in fittings body one end, and installs Sealing in described groove, can well fixing seals, and do not make it be shifted or come off, leakage of oil risk is low and easy for installation.

Fig. 1 is the structural representation sectional drawing of a kind of oil connection embodiment of the utility model;
In figure: 1, fittings body, 2, nut, 3, O shape circle, 4, groove, 5, transit joint, 6, catch, the 7, first bulge loop, the 8, second bulge loop, 9, groove.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " one end ", " the other end ", " root ", " end face " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristics.Thus, be limited with " first ", the feature of " second " can express or impliedly comprise one or more these features.
For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
With reference to Fig. 1, show the structural representation sectional drawing of a kind of oil connection embodiment of the utility model, a kind of oil connection, comprise: nut 2 and fittings body 1, fittings body 1 outer wall is provided with the first bulge loop 7 and the second bulge loop 8, this first bulge loop 7 and the second bulge loop 8 are cylindrical structural, can also be rectangular configuration according to the shape of fittings body 1, first bulge loop 7 is provided with catch 6, groove 4 is formed between first bulge loop 7 and the second bulge loop 8, this fittings body 1 is specially the axis of guide in the present embodiment, this axis of guide is tubular, it can also be rectangle, use the axis of guide as fittings body, wear resistance is good and convenient install.
Nut 2 is specially a kind of self-locking nut in the present embodiment, also can be that other specifically tighten up the nut of function, this nut 2 endoporus is provided with internal thread, catch 6 is connected with the internal thread of nut 2, nut 2 is removable to be arranged in groove 4, one end of fittings body 1 is connected on the internal thread of nut 2, one end of fittings body 1 attaching nut 2 is sealed department, on the outer circumferential face of sealed department, hoop is provided with groove 9, in groove 9, Sealing is installed, the seal is specially O shape circle 3 in the present embodiment, this O shape circle 3 is quality of rubber materials, can also be other materials such as metal, O shape circle 3 is located in groove 9, not easily make O shape enclose 3 move or come off, better sealing effect can be reached, nut 2 is connected with transit joint 5, transit joint 5 is provided with annular outside thread, the internal thread of institute's nut 2 connects removably to be tightened, fittings body 1 is pressed in by O shape circle 3, thus reach better sealing effect.
The structural representation sectional drawing of a kind of oil connection embodiment as shown in Figure 1; in the utility model, the shape of butt joint body 1 and quantity are not limited; as long as be provided with groove 9 on fittings body 1, and be provided with Sealing in groove 9, all in the utility model protection domain.Such as: fittings body 1 can be " one " character form structure, also can be " L " shape structure, fittings body 1 two ends are all connected with nut 2, and the two ends of attaching nut 2 are all set to sealed department, on the outer circumferential face of two sealed departments, hoop is provided with groove 9, O shape circle 3 is fixed in groove 9, the internal thread of nut 2 is fixedly connected with the outside thread of transit joint and tightens, the two ends of fittings body are pressed in by O shape circle 3, can better be connected and sealed to oil pipe like this, and dissimilar oil connection can be met, installation specification is low, and convenient.
