Abstract
The utility model discloses an automotive oil pipe joint. The oil pipe joint comprises a nut and a connecting ring integrally connected with the nut, wherein round through holes are formed inside the nut and the connecting ring, an outer thread is arranged outside the connecting ring, and the outer thread is divided into a first outer thread and a second outer thread; the first outer thread is arranged adjacent to one end of the nut, the second outer thread is arranged at the front end of a radial nut screwing direction, and the round holes are provided with smooth inner walls; the first thread is a coarse thread, and the second thread is fine thread. By adopting the designing scheme provided by the utility model, the joint is connected with an another pipeline after being connected to an oil pipe, the coarse thread is matched with an inner thread of the pipeline, and an outer fine thread is matched up with another inner thread in the oil pipe, and the pipeline matched up with the fine thread is more compact, so that the tightness of the connection of pipelines can be improved.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of automobile oil pipe joint.
Background technique
Existing automobile oil pipe joint adopts the interface with screw-thread fit mostly, and in the outer wall setting of oil pipe, the internal thread coordinating with oil tube external thread the setting of the oil pipe the other end, completes the connection of oil pipe.But the connection of general major thread inevitably exists gap, and threaded coupling also seals with sealer or sealing gasket, and its manufacture cost is higher, and sealing effect is poor, easily causes leakage of oil.
Summary of the invention
The purpose of this utility model is to design a kind of automobile oil pipe joint.
To be solved in the utility model is the poor problem of existing oil connection sealing effect.
The technical solution of the utility model is: the connecting ring that comprises nut and be connected as a single entity with nut, described nut and connecting ring inner side are provided with manhole, described connecting ring outside is provided with outside thread, described outside thread is divided into the first outside thread and the second outside thread, the first outside thread is located near nut one end, the second outside thread is located at the radially front end of tightening direction of nut, and described manhole is smooth inner wall.
Described the first screw thread is coarse thread, and the second screw thread is fine thread.
Adopt design proposal of the present utility model, after joint access oil pipe, be connected with other pipeline, by the screw-internal thread fit of coarse external screw thread and pipeline, closely-pitched outside thread with oil pipe in another screw-internal thread fit, pipeline after coordinating with fine thread, tightr, thus the sealing while connection between pipeline increased.
The utlity model has good sealing effect advantage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the connecting ring 4 that the utility model comprises nut 2 and is connected as a single entity with nut 2, described nut 2 is provided with manhole 1 with connecting ring 4 inner sides, described connecting ring 4 outsides are provided with outside thread, described outside thread is divided into the first outside thread 3 and the second outside thread 4, the first outside thread 3 is located near nut 2 one end, the second outside thread 4 is located at the radially front end of tightening direction of nut 2, described manhole 1 is smooth inner wall, described the first screw thread 3 is coarse thread, the second screw thread 4 is fine thread, adopt design proposal of the present utility model, after joint access oil pipe, be connected with other pipeline, by the screw-internal thread fit of coarse external screw thread and pipeline, closely-pitched outside thread with oil pipe in another screw-internal thread fit, pipeline after coordinating with fine thread, tightr, thereby increase the sealing while connection between pipeline.
