Abstract

A hose connector is an important component connecting a hydraulic device with a rubber hose. The hose connector comprises a hollow connector rod core and a nut sleeved on the lower portion of the connector rod core. An annular pressing shoulder is arranged on the upper portion of the nut, and an annular blocking shoulder used for being pressed by the annular pressing shoulder is arranged on the lower portion of the connector rod core. The bottom of an inner cavity of the connector rod core is provided with a cone-shaped face, the end of the cone-shaped face with a small diameter faces upwards, two side lines on the cone-shaped face form an included angle alpha of 45 degrees to 55 degrees, the two side lines are symmetrical based on the axis of the connector rod core, an annular groove is arranged in the cone-shaped face, and sealing rings are arranged in the annular groove. After the hose connector is connected with a pipeline in the hydraulic device, the sealing effect is good.

Description

Hose coupling
Technical field:
The utility model relates to a kind of joint, specifically is a kind of hose coupling for flexible pipe being connected on the hydraulic equipment.
Background technique:
Present hose coupling generally comprises hollow connector rod core and the nut that is enclosed within connector rod core bottom, the connector rod core is connected on the pipeline in the hydraulic equipment by nut, behind the fastening nut, connector rod core one end end face can be close to pipeline one end end face, and produce resiliently deformable at the place of being close to and seal, yet, because connector rod core and pipeline are hollow-core construction, its area of contact is very little, it only is the facet of an annular, therefore, above-mentioned hose coupling sealing effect in actual use is not very desirable.
The model utility content:
The technical problems to be solved in the utility model is, provide pipeline a kind of and in the hydraulic equipment to be connected after, sealing effect is hose coupling preferably.
Technical solution of the present utility model is, provide a kind of hose coupling with following structure: comprise hollow connector rod core and the nut that is enclosed within connector rod core bottom, nut top is provided with annular and presses shoulder, connector rod core bottom is provided with the annular shoulder block of pressing shoulder to push down for annular, wherein, bottom, connector rod in-core chamber is provided with conical surface, and the smaller diameter end of conical surface up, have annular groove on the conical surface, be provided with seal ring in the annular groove.
Hose coupling described in the utility model, wherein, on the conical surface take the symmetrical formed angle α in two sidelines of connector rod wire mandrel as 45 °~55 °.
Hose coupling described in the utility model, wherein, angle α is 50 °.
After adopting above structure, compared with prior art, the utility model hose coupling has the following advantages: after the conical surface of connector rod in-core chamber bottom is inserted on the cone boss that pipeline one end sets in advance, greatly increased the area of contact of connector rod core and pipeline, in addition, also be provided with seal ring on the conical surface, under the acting in conjunction of these two kinds of structures, the utility model hose coupling will have comparatively ideal sealing effect with after pipeline is connected.
Sealing effect after 45 °~55 ° angle α can further improve the connector rod core and pipeline be connected.
50 ° angle α is the preferred forms of the utility model hose coupling.
Description of drawings:
Fig. 1 is that the master of the utility model hose coupling looks the sectional structure schematic diagram.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model hose coupling is described in further detail:
As shown in Figure 1, in this embodiment, the utility model hose coupling comprises hollow connector rod core 1 and the nut 4 that is enclosed within connector rod core 1 bottom, nut 4 tops are provided with annular and press shoulder 2, connector rod core 1 bottom is provided with for annular and presses the shoulder 2 annular shoulder blocks 3 of pushing down, connector rod core 1 intracavity bottom is provided with conical surface 5, the smaller diameter end of conical surface 5 up, on the conical surface 5 take the symmetrical formed angle α in two sidelines of connector rod core 1 axis as 50 °, have annular groove 7 on the conical surface 5, be provided with seal ring 6 in the annular groove 7.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
