Description
Technical field
The utility model relates to link field, special relevant to a kind of sealing configuration of hose coupling.
Background technique
As shown in Figure 1, 2, for a kind of more common hose coupling structure at present, rivet clasp one joint 1 ' on the port of flexible pipe, flexible pipe front end is accessed in attaching nut 2 ' and is connected with external piece together with joint 1 ', the shaping block edge 3 ' in front end of usual joint 1 ', upper installation one pad 4 ' of block edge 3 ', sealing is realized by this pad 4 ' when joint 1 ' is connected with external piece, after the locking of this hose coupling two ends, use middle flexible pipe jointing can be caused stuck or break because reversing or being wound around, flexible pipe is low for working life; And not easily Screw joint or easy dislocation cause poor sealing and leak when prior art adopts the discovery of the sealing configuration of pad to connect, the hardening and permanent deformation of meeting after the permanent pressurized of pad in addition, and then cause seal failure and leak.The improvement that the utility model is namely not enough for this and carry out, this case produces thus.
Model utility content
The utility model provides a kind of hose coupling to seal spin structure, to solve during the not good and flexible pipe of hose coupling sealing in prior art uses the problem easily twisting or be wound around.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of hose coupling sealing spin structure, include flexible pipe, spin core, attaching nut and connecting sleeve, one end of described spin core is fixedly connected with flexible pipe, the other end protrudes flexible pipe outward for being connected with external piece rotatable sealing, and this other end is provided with the SEALING FITTING connecing with external piece and mate in hole; What described attaching nut loosened is nested with in the outside of flexible pipe with spin core, and the inwall of this attaching nut is provided with the internal thread be connected with external piece; Described stuffing box gland gap is nested with on spin core, and spin core is positioned in attaching nut by sealing cover.
The inwall of described attaching nut is provided with defining flange.
Described spin core SEALING FITTING is a shaping step surface near the side of flexible pipe.
The middle part of described stuffing box gland is provided with trepanning, the shaping ring edge in end, and the aperture of trepanning is provided with step, and this step-shaped top is held on the step surface of spin core, and ring edge contact is on the defining flange of attaching nut.
The outer wall of described spin core SEALING FITTING is provided with the annular groove of seal ring and accommodating sealing circle.
One end that described spin core is connected with flexible pipe is provided with cutting graftage part, and the surface of this cutting graftage part is laid with dentation rib.
Adopt said structure, the utility model attaching nut and external piece screw tight in connection procedure, drive the SEALING FITTING of spin core to stretch into external piece and connect composition rotatable sealing connection in hole, this structure strengthens the sealing effect of interface, effectively avoid the hidden danger of leaking, and after connecting, the utility model spin core can rotate relative to external piece and attaching nut with flexible pipe and realize spin function.
Accompanying drawing explanation
Fig. 1,2 is the structure of existing hose coupling and the state of enforcement sectional view;
Fig. 3,4 is structure of the present utility model and the state of enforcement sectional view.
Embodiment
Below in conjunction with accompanying drawing and concrete enforcement, the utility model is elaborated.
As shown in Figure 3,4, the utility model hose coupling sealing spin structure, include flexible pipe 1, spin core 2, attaching nut 3 and connecting sleeve 4, the middle part of described spin core 2 is provided with class's through hole, one end is fixedly connected with flexible pipe 1, this one end forms the cutting graftage part 21 stretching into flexible pipe 1, the surface of cutting graftage part 21 is laid with dentation rib 22; The other end of spin core 2 protrudes outside flexible pipe 1, for with external piece A(as gondola water faucet, inlet valve joint etc.) rotatable sealing is connected, this the other end is provided with SEALING FITTING 23, the internal diameter that the external diameter of sealing joint 23 and external piece A connect hole matches, what during connection, SEALING FITTING 23 stretched into external piece A connects in hole, the outer wall of SEALING FITTING 23 is provided with the annular groove 25 of seal ring 24 and accommodating sealing circle 24, and SEALING FITTING 23 near the side of flexible pipe an also shaping step surface 26;
What described attaching nut 3 loosened is nested with in the outside of flexible pipe 1 with spin core 2, and this attaching nut 3 is horn-like hollow sleeve, and inwall is provided with the internal thread 31 be connected with external piece;
Described stuffing box gland 4 gap is nested with on spin core 1, spin core 1 is positioned in attaching nut 3 by sealing cover 4, this attaching nut 3 inwall is provided with the defining flange 32 of location spin core 1, the middle part of described stuffing box gland 4 is provided with trepanning 41, the shaping ring edge 42 in end, the aperture of trepanning 41 is provided with step 411, and this step 411 holds on the step surface 26 of spin core, and ring edge 42 contact is on the defining flange 32 of attaching nut 3.
Adopt said structure, attaching nut 3 and external piece screw tight in connection procedure, drive the SEALING FITTING 23 of spin core 2 to stretch into connecing in hole of external piece A to realize being tightly connected, compared with prior art the sealing of the section of pad is optimized for the circumferential sealing of SEALING FITTING by the utility model, enhance sealing effect, combination seal cover simultaneously, further lift-off seal effect, effectively avoid the hidden danger of leaking, and after connecting, the utility model spin core can rotate relative to external piece and attaching nut with flexible pipe and realize spin function.
The above, be only preferred embodiment of the present utility model, be not used for limit the utility model implement scope.Therefore the change in every case done according to claim of the present utility model and specification or modification, all should belong within scope that the utility model patent contains.
