Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of flexible hose joint.
Background technique
Pipeline in daily life is mainly used for carrying fluid, as being applied in the conveying of gas or liquid, but, in actual use, the group of general pipeline is established and often need be used pipe joint, is completed the connection between tube and tube, therefore by the connection of pipe joint, the convenience that suitable pipe joint structure design concerns in use, and the function needed for Consumer can be met.
Model utility content
The purpose of this utility model is to provide a kind of flexible hose joint, solves the technical problem of flexible hose joint tensile resistance difference in prior art.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of flexible hose joint, comprises nut, adapter sleeve and locking sliding sleeve, described nut has been wholely set core pipe with nut, and the end periphery wall of described core pipe is provided with some pawls; Core pipe extends in insertion adapter sleeve, and is connected with adapter sleeve by screw thread, also leaves the annular space for accommodating flexible hose braid between adapter sleeve and core pipe; Described locking sliding sleeve is sleeved on adapter sleeve periphery, and the afterbody of locking sliding sleeve extends beyond the afterbody of adapter sleeve, and the inwall of locking sliding sleeve is also provided with for oppressing adapter sleeve to enterolithic inner conical surface; The periphery wall of described adapter sleeve is also provided with locking sliding sleeve limited step.
The afterbody periphery wall of described adapter sleeve offers and subtracts wall groove, described in subtract wall groove ringwise.What adapter sleeve subtracts wall groove is arranged so that adapter sleeve afterbody easily inwardly deforms, and avoid adapter sleeve Folding Deformation, brute force effectively oppresses braid, ensures connection reliability.
The front inner wall of described locking sliding sleeve with described subtract wall groove corresponding be provided with arc convex.During non-working condition, arc convex can be made to be in and subtract in wall groove, when installing and using, arc convex decreases the surface of contact between locking sliding sleeve inwall and adapter sleeve periphery wall, consequently reduce force of sliding friction when locking sliding sleeve is installed, make installation more convenient.
The front port inwall of described locking sliding sleeve also offers the guiding conical surface, and described guide cone face extends inwardly to described arc convex.The setting of the guiding conical surface is convenient to adapter sleeve and is press-fitted in locking sliding sleeve, has locking sliding sleeve and installs leading role.
The periphery of described locking sliding sleeve is provided with anti-slip veins.The setting of anti-slip veins can be avoided locking to slide in assembly process occurring skidding.
The inwall of described core pipe offers some circular grooves one, and in described circular groove, one is provided with seal ring one.The setting of seal ring one can increase the sealability between core pipe and hookah bodies, avoids fed sheet of a media to leak.
Described locking sliding sleeve limited step offers some circular grooves two, in described circular groove two, is provided with seal ring two.Arranging of seal ring two strengthens sealability of the present utility model further.
The tapered contraction of afterbody of described core pipe.Taper is shunk project organization and is facilitated core pipe to insert between braid and flexible pipe.
When the utility model uses, the braid of flexible hose is inserted in annular space, hookah bodies stretches in core pipe, then locking sliding sleeve is axially pushed forward until locking sliding sleeve limited step on adapter sleeve periphery wall, the inner conical surface of locking sliding sleeve inwall in the process will oppress adapter sleeve to internal strain, in the pawl of braid by adapter sleeve distortion compressing embedded core pipe, flexible hose is fixed, and nut place end is directly connected with use instrument or other pipe fitting screw threads by screw thread.Compared with prior art, the beneficial effect that the utility model reaches is: the end of core pipe is provided with some pawls, realizes the reliable fixing of braid, can significantly improve the axial tensile resistance of flexible hose joint through adapter sleeve distortion compressing; Be provided with multiple-sealed circle and can significantly improve sealability of the present utility model.
Accompanying drawing explanation
Fig. 1 is the utility model non-working condition structural representation.
Fig. 2 is the utility model using state structural representation.
In figure: 1, nut; 2, core pipe; 2a, pawl; 3, adapter sleeve; 3a, subtract wall groove; 4, seal ring one; 5, sliding sleeve is locked; 5a, inner conical surface; 5b, arc convex; 6, anti-slip veins; 7, seal ring two; 8, braid; 9, hookah bodies.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, nut 1 has been wholely set core pipe 2 with nut 1, core pipe 2 extends in insertion adapter sleeve 3, and is connected with adapter sleeve 3 by screw thread.The end periphery wall of core pipe 2 is provided with some pawl 2a, inserts between braid 8 and hookah bodies 9, the tapered contraction of afterbody of core pipe 2 for convenience of core pipe 2.The inwall of core pipe 2 offers some circular grooves one, in circular groove, one is provided with seal ring 1.
Leave the annular space for accommodating flexible hose braid 8 between adapter sleeve 3 and core pipe 2, the head periphery wall of adapter sleeve 3 is also provided with locking sliding sleeve 5 limited step, afterbody periphery wall offers and subtracts wall groove 3a, subtracts wall groove 3a ringwise.
Locking sliding sleeve 5 is sleeved on adapter sleeve 3 periphery, and the afterbody of locking sliding sleeve 5 extends beyond the afterbody of adapter sleeve 3, and the inwall of locking sliding sleeve 5 is also provided with for oppressing adapter sleeve 3 to enterolithic inner conical surface 5a.Locking sliding sleeve 5 front inner wall corresponding with subtracting wall groove 3a be provided with arc convex 5b.During non-working condition, arc convex 5b can be made to be in and to subtract in wall groove 3a.The front port inwall of locking sliding sleeve 5 also offers the guiding conical surface, and guide cone face extends inwardly to arc convex 5b, and the setting of the guiding conical surface is convenient to adapter sleeve 3 and is press-fitted in locking sliding sleeve 5, has locking sliding sleeve 5 and installs leading role.In order to avoid locking sliding sleeve 5 occurs skidding in assembly process, the periphery of locking sliding sleeve 5 is also provided with anti-slip veins 6.For strengthening sealability of the present utility model further, locking sliding sleeve 5 limited step offering some circular grooves two, in circular groove two, is provided with seal ring 27.
When the utility model uses, the braid 8 of flexible hose is inserted in annular space, hookah bodies 9 stretches in core pipe 2, then locking sliding sleeve 5 is axially pushed forward until locking sliding sleeve 5 limited step on adapter sleeve 3 periphery wall, the inner conical surface 5a locking sliding sleeve 5 inwall in the process will oppress adapter sleeve 3 to internal strain, braid 8 is out of shape in the pawl 2a of compressing embedded core pipe 2 by adapter sleeve 3, flexible hose is fixed, and nut 1 place end is directly connected with use instrument or other pipe fitting screw threads by screw thread.The structural representation assembled, as shown in Figure 2.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
