Abstract
The utility model discloses a rubber hose connector. The rubber hose connector comprises a connector body (1), wherein a bamboo joint structure (1.1) is arranged on the connector body (1), one end of the connector body (1) is of a circular truncated cone shape, and the included angle a between the extension line of the side line of the cross section of one end of the connector body (1) and the central axis of one end of the connector body (1) is 15-25 degrees. The rubber hose connector is reliable in connection and good in sealing performance.
Description
Technical field
The utility model relates to a kind of rubber hose coupling.
Background technique
At present, on internal combustion locomotive the connection between useful oil pipe (being all generally sebific duct), be all to connect by simple nut, so have always that sealing is poor, a leakage of oil, the poor problem of soundness, cause unnecessary waste, and connect loosening phenomenon generation, affect working efficiency.
The model utility content
The technical problems to be solved in the utility model is that a kind of rubber hose coupling reliable, good airproof performance that connects is provided.
Technical solution of the present utility model is, a kind of rubber hose coupling with following structure is provided, and comprises joint body, and described joint body is provided with bamboo joint structure, and an end of joint body is round table-like; The angle a that forms between the central axis of the elongation line in the sideline of the cross section of one end of described joint body and an end of described joint body is 15 ~ 25 °.
After adopting above structure, rubber hose coupling of the present utility model compared with prior art, has the following advantages:
Because an end of the joint body of rubber hose coupling of the present utility model is round table-like, the angle a that forms between the central axis of the elongation line in the sideline of the cross section of one end of described joint body and an end of described joint body is 15 ~ 25 °, when making like this rubber hose coupling of the present utility model and supporting sebific duct round table surface coordinating, sealing effect is better, avoids occurring the phenomenon of leakage of oil.
As a kind of improvement of the present utility model, described angle a is 20 °.Be optimum implementation.
As another kind of improvement the of the present utility model, an end of described joint body is sheathed with set screw nut outward.After adopting this kind structure, convenient fixing and installation are firmly.
Also have a kind of improvement as of the present utility model, the end face of an end of described joint body is provided with annular seal groove, is provided with seal ring in described annular seal groove.After adopting this kind structure, sealing effect more.
Also have a kind of improvement as of the present utility model, the angle b that forms between the central axis of an end of the center line of the cross section of described annular seal groove and described joint body is 25 ~ 35 °.After adopting this kind structure, seal ring is aimed at annular seal groove, then just axially pressing along an end of joint body to be fit in annular seal groove, it is quite convenient to install, and the seal ring that be arranged in annular seal groove this moment is in extended state, contact closelyr between seal ring and annular seal groove, therefore, the sealing effect of seal ring is better.
Also have a kind of improvement as of the present utility model, described b is 30 °.This kind structure is optimum implementation.
