Abstract
The utility model relates to a rubber hose connector which is an important part for connecting hydraulic equipment and a rubber hose. The rubber hose connector comprises a hollow connector rod core and a nut, wherein the nut is sleeved on the lower part of the hollow connector rod core, and the nut is provided with an annular press shoulder; the lower part of the hollow connector rod core is provided with an annular shoulder ring which can be pressed by the annular press shoulder; the bottom of the annular shoulder ring is provided with a hollow tapered boss; the hollow tapered boss is communicated with the hollow connector rod core; the large-diameter end of the hollow tapered boss is positioned on the upper part of the small-diameter end; an induced angle formed by two side lines, which are symmetrical through the axial line of the hollow connector rod core, of the hollow tapered boss is 35-45 degrees; the peripheral wall of the hollow tapered boss is provided with an annular groove; and the annular groove is internally provided with a sealing ring. The rubber hose connector disclosed by the utility model is better in sealing effect after being connected with a pipeline inside the hydraulic equipment.
Description
Technical field:
The utility model relates to a kind of joint, specifically is a kind of rubber hose connection for flexible pipe being connected on the hydraulic equipment.
Background technique:
Present rubber hose connection 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 of 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 rubber hose connection 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 rubber hose connection preferably.
Technical solution of the present utility model is, provide a kind of rubber hose connection 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, annular shoulder block bottom is provided with hollow cone boss, hollow cone boss communicates with hollow connector rod core, the larger diameter end of cone boss is positioned at smaller diameter end top, have annular groove on the cone boss periphery wall, be provided with seal ring in the annular groove.
Rubber hose connection described in the utility model, wherein, on the cone boss take the symmetrical formed angle α in two sidelines of connector rod wire mandrel as 35 °～45 °.
Rubber hose connection described in the utility model, wherein, angle α is 40 °.
After adopting above structure, compared with prior art, the utility model rubber hose connection has the following advantages: after in the cone shape hole that cone boss insertion 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 cone boss, under the acting in conjunction of these two kinds of structures, the utility model rubber hose connection will have comparatively ideal sealing effect with after pipeline is connected.
Sealing effect after 35 °～45 ° angle α can further improve the connector rod core and pipeline be connected.
40 ° angle α is the preferred forms of the utility model rubber hose connection.
Description of drawings:
Fig. 1 is that the master of the utility model rubber hose connection looks the sectional structure schematic diagram.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model rubber hose connection is described in further detail:
As shown in Figure 1, in this embodiment, the utility model rubber hose connection comprises hollow connector rod core 1 and the nut 5 that is enclosed within connector rod core 1 bottom, nut 5 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, annular shoulder block 3 bottoms are provided with hollow cone boss 4, hollow cone boss 4 communicates with hollow connector rod core 1, the larger diameter end of cone boss 4 is positioned at smaller diameter end top, on the cone boss 4 take the symmetrical formed angle α in two sidelines of connector rod core 1 axis as 40 °, have annular groove 7 on cone boss 4 periphery walls, 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.
