Description
Technical field
This utility model relates to a kind of pipeline, the attachment structure of a kind of pipeline.
Background technology
At present, along with the development of market economy, pipeline transportation is in the ascendant, and particularly the application of liquid conveying pipe is more
Extensively, for promoting that the liquid such as water oil flow in pipeline, fluid flows in pipeline and must keep the pressure of certain orientation, pipeline
Manufacturing generally regular length standard, during use, mutually assembly links together again, and in order to prevent seepage, stitching portion is general
Must do special handling, such as, use the mode that screw thread spins, special tool(s) car on-the-spot must be used to go out screw thread thread, screw socket wraps up
Unsintered tape is to strengthen sealing, more involutory screws, and, when actually used, the length of required pipeline differs, and causes using
The pipeline of standard system length is in connection procedure, and the pipeline of end is not necessarily lucky conformance with standard standard length, at this moment
Be subjected to first block, then the cumbersome process such as car tooth, sealing, time and effort consuming and it is necessary to be aided with special tool(s) can not, to installation
The technology of the technical staff of pipeline requires the highest, and in order to improve installation effectiveness, applicant once proposed with regard to following technical scheme
Chinese patent application: a kind of metallic conduit attachment means, including the first pipeline and second pipe, also includes adjustable joint, interior connection
Pipe and clip detent mechanism；The caliber of the loose joint end of described adjustable joint is less than the bore of described first pipeline, and described loose joint
The loose joint end of pipe inserts described first pipeline makes the loose joint end of described adjustable joint dock with described first seal for pipe joints；Described loose joint
The positioning end of pipe sets adjustable joint connecting tube, and the bore of described adjustable joint connecting tube is more than the bore of described adjustable joint；Described
Inner connection tube external diameter less than the bore of described adjustable joint connecting tube and the bore of second pipe, by described interior connection
Described adjustable joint connecting tube is inserted at the two ends of pipe respectively, second pipe makes described adjustable joint connecting tube seal with described second pipe
Docking, described adjustable joint connecting tube is axially positioned connected with described second pipe by described clip detent mechanism.Though this scheme
So simplifying installation procedure, also without special tool(s), part improves installation effectiveness, but there is also adjustable joint and be connected firmly the most not
By force, when manifold pressure is the biggest, adjustable joint may be made easily to deviate from, and the more high drawback of production cost of pipeline.
Utility model content
For above-mentioned technical problem, it is low that this utility model provides a kind of simple installation, cost of labor, maintenance cost, and
Achieve the pipe connecting structure of stepless retractable.
The technical solution of the utility model includes: the flexible attachment structure of liquid conveying pipe, including sleeve pipe and intubate,
Wherein, the one end intubated is connected with one end of sleeve pipe, it is characterised in that described sleeve pipe with intubate the port being connected be provided with to
A few gap, is provided with screw thread by described gap, is additionally provided with the swivel nut spun with threaded adapter, and the internal diameter of described swivel nut is from oral area
Reduce to bottom.Complete sleeve pipe is the most stable due to structure, is susceptible to external force deformation, and gap then changes being subject to about
Power stability, the tube wall around gap supports without connecting, and when being extruded by external force, can slope inwardly deformation.Insertion set will be intubated
Guan Hou, firmly rotary sleeve swivel nut at sleeve port, along with the occlusion precession of thread, the port of sleeve pipe is by from the screw socket of swivel nut
Reaching at the bottom of spiral shell, owing to the internal diameter of swivel nut reduces to bottom from oral area, the tube wall of opening position is produced by the extruding bottom swivel nut at last
Raw deformation, tilts to the outer wall intubated, and is tightly pressed on the outer wall intubated, it is achieved thereby that sleeve pipe and the tight jail intubated
It is solidly connected.Owing to using spiral compression mode, sleeve pipe with intubate no matter can intubate concrete insertion in the range of adaptive grafting
Sleeve pipe where, all can closely crimp, it is achieved that freely stretch, and locks without shelves.The internal diameter of described swivel nut from oral area the end of to
The implementation that portion reduces, can be that the tooth footpath change of thread itself is as little in oral area bottom greatly, it is also possible to be that tooth footpath is constant, and
The near-bottom of swivel nut sets a ramp, and the cross section of ramp can be trapezoidal.
A better embodiment of the present utility model is that described gap is U-shaped.
A better embodiment of the present utility model is that described gap is three.Each gap is equally spaced.
A better embodiment of the present utility model is to be provided with stage portion at the mouth of pipe of sleeve pipe, and described gap is located at set
In the stage portion of pipe.In this way so that the tube wall at the mouth of pipe is relatively thin, the most relatively have more elasticity, yielding, special
It is not for metallic conduit.
A better embodiment of the present utility model is that described sleeve pipe is provided inwardly with convex on the tube wall near gap
Point.Design due to salient point so that the tube wall of opening position is deformed inward when pressing to intubate, be salient point crimping and non-face contact insert
Pipe so that crimp more stable.
A better embodiment of the present utility model is, to being externally provided with bulge loop on described cannula outer wall.Described bulge loop can
Being the most integrally to be rolled into arch form by sleeve pipe, it is also possible to be inwardly to be rolled grooving by sleeve pipe, then place ring, ring in groove
The diameter of circle, more than the degree of depth of groove, is similar to sealing ring and the design of seal groove.Bulge loop is set and is inserted into intubating and turning round when sleeve pipe
After tight swivel nut, after bulge loop is against salient point just, then can the connection of reinforcing sleeve and sleeve further fix.Certainly, if
In practice, intubating insertion sleeve pipe relatively deep, fixing rear bulge loop is not directly to abut with salient point, but bulge loop is now prevented from
Reversely maloperation, such as, if there being people will intubate reverse withdrawing, when intubating withdrawing to after certain distance, the salient point intubated still can
Abutting to bulge loop thereafter, unless unscrewed swivel nut, being otherwise difficult to completely detach out from sleeve pipe by intubating.
Advantageous Effects of the present utility model includes: simple in construction, simple installation, cost of labor and maintenance cost be low,
Can be according to beneficial effects such as the length of erecting bed practical situation regulation connection pipeline.
This utility model can be used for the connection of various fluid line and installs.

Detailed description of the invention
Embodiment one
As shown in Figure 1, Figure 2, Figure 3 shows, sleeve pipe 1 is provided with screw thread 1.2, and the port of sleeve pipe 1 is provided with stage portion 1.3, step
Being provided with three gap 1.1 at portion 1.3, the front end of swivel nut 3 is provided with internal screw thread 3.1, and bottom is provided with ramp 3.2, will intubate 2 and put
Insert in sleeve pipe 1 after swivel nut 3, then the thread 3.1 of swivel nut 3 is made relative turn-knob action with the screw thread 1.2 of sleeve pipe 1, until twisting
Tightly, now the outer wall mouth of sleeve pipe 1 is against in the ramp 3.2 of swivel nut 3, and the horizontal force that swivel nut 3 is threaded into and produces is by ramp
3.2 resolve into a downward pressure, and this pressure is executed in the stage portion 1.3 of sleeve pipe 1, and stage portion 1.3 is inwardly stressed generation
Deformation, thus the inwall test of stage portion 1.3 is until supporting on the outer wall being attached to intubate 2, define one metastable fixing
State.
