Concrete meaning in the present invention.
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of plastic tube and coupling, including 7, two housings 1 of a main body and a bushing 18, institute
It states and bushing 18 is set from middle part to one end in 7 inner hole of main body, two housings 1 are respectively sleeved in the periphery of main body 7, outside the main body 7
There is annular groove 12 among all, the shaft shoulder 13 is arranged in 12 two sides of annular groove, and setting is anti-on the shaft shoulder 13 is disengaged from the groove 8, and the anti-decylization 2 is
Section is the annular projection of triangle, is the smallest internal diameter in convex apexes, that is, anti-decylization of annular projection at A, described to prevent being disengaged from the groove
8 be that the spill that section is triangle is cyclic annular, is the cricoid recess minimum point of spill at B, i.e., anti-to be disengaged from the groove the smallest internal diameter on 8.
As shown in figure 3,7 periphery of main body sets gradually the shaft shoulder 13,14 and of the first ladder outer circle from annular groove 12 to left end
Second ladder outer circle 16, the circumference that the first ladder outer circle 14 and the second ladder outer circle 16 are in contact are that the first circular shape is convex
15 are played, the main body 7 is interior to set gradually the first inner hole 9, the second inner hole 17 and third inner hole 27, the annular groove by centre to both ends
12 positions correspond to the first inner hole 9, the position and the second inner hole 17 of the first ladder outer circle 14 and the second ladder outer circle 16
Corresponding, the position of the 5th ladder outer circle 28 and the 6th ladder outer circle 30 is corresponding with third inner hole 27.
As shown in figure 5, there is a trapezoidal annular protrusion 21 in described 18 outer surface one end of bushing, the annular protrusion 21 is to the other end
Set gradually third ladder outer circle 20, fourth order ladder outer circle 19 and rectangular recess 23.
As shown in fig. 7 ,-first pipe 25 and second pipe 26 are locally deformed C after strongly being squeezed, deformation C enters
In rectangular recess 23；
Housing both ends apply pressure along axial by hydraulic installation tool respectively, and it is the first circle that the second circular conical surface 6, which squeezes circumference,
Arc convex 15 and the second arc-shaped convex 29, make main body be deformed clamping pipe, and left side pipeline is locally deformed and is pressed
Enter in the rectangular recess 23 of bushing, right side pipeline is engaged by the first sealing ring 11 of main body and the second sealing ring 22, two side ducts
All secured connection and sealing are realized with connector.
Prevent being disengaged from the groove in 8 in addition, anti-decylization 2 enters, plays the role of locking, housing is locked in main body securely, is prevented
Under bigger external force, housing is slipped from main body, guarantees that connection is stronger.
Working principle:
First main body and bushing are installed before construction, housing pre-pressing but not in place, purpose be intended merely to make housing, main body and
Bushing is integrally formed, and facilitates pick-and-place, this work is completed in connector factory.When construction and installation, pipeline is first cut to size simultaneously
Nozzle burr is handled, a segment pipe is inserted into main body and bushing crack from one end, another segment pipe is inserted into from one end
In main body inner hole, the housing after precompressed is finally pressed with dedicated hydraulic installation tool, outer situation is shown in figure after pressing
6, main body clamping pipe, one end pipeline local deformation are pressed into bushing groove at this time, and other end pipeline is by the first sealing of main body
Ring 11 and the occlusion of the second sealing ring 22, connector, which realizes pipeline, to be reliably connected and seals.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
