Specific embodiment
Below in conjunction with the accompanying drawings and implementation method is conducted further description to the present invention：
As shown in figure 1, a kind of pipeline connecting assemble, including pipe fitting 10 and external member 20, two external members 20 are respectively fitted over pipe fitting 10
Two ends.
In the present embodiment, the material of pipe fitting 10 is stainless steel, and the material of external member 20 is aluminium alloy.Stainless-steel pipe is processed
Pipe fitting 10 is formed, the pipeline connecting assemble pressure-bearing property after assembling is good, and can farthest reduce cost of material, while reducing
The weight of whole assembling assembly, is readily transported and installs.
As shown in Fig. 2 pipe fitting 10 includes connecting cylinder 11, the wall thickness of connecting cylinder 11 is 1.0mm, the energy of connecting cylinder 11 of the thickness
Enough fully ensure that the load performance of connecting cylinder 11, moreover it is possible to save raw materials for production, it is cost-effective.
The middle part of connecting cylinder 11 caves inward to form outside depression, the connected unit 12 of internal protrusion, connected unit 12 be connected
Cylinder 11 is connected by buffer edge 13.Connecting cylinder 11 positioned at the both sides of connected unit 12 is provided with outwardly seal groove 14, is close to
The edge of connecting cylinder 11 is provided with through hole.Connected unit 12 can play a part of positioning when pipeline is inserted, it is to avoid pipeline occur and insert
Enter the too deep or not enough situation of insertion.
A diameter of 4.2mm of the arc section of seal groove 14 correspondence circular arc；Seal groove 14 is less than it with the distance of connected unit 12
With the distance at the edge of connecting cylinder 11, pipeline to be connected can be avoided from being difficult to enter when packing into connecting cylinder 11, sealing ring 30 is just
It will not be caused when pipeline is in insertion to hinder, it is easier for installation, while also can fully ensure that between the two is close
Sealing property；The angle of the arc section of seal groove 14 correspondence central angle is more than 180 degree so that after sealing ring 30 packs into seal groove 14,
The lower end of sealing ring 30 can exceed the lower edge of seal groove 14 so that sealing ring 30 can be fully contacted with pipe fitting to be connected；
Cause that sealing ring 30 is difficult to be come off from seal groove 14 simultaneously, connect even closer.
Buffer edge 13 is curved with the junction of connected unit 12 and connecting cylinder 11, when pipeline to be connected is inserted in and company
Connect platform 12 to offset, the junction of arc can play cushioning effect, while the place of connected unit 12 can be ensured will not easily let out
Leakage.
As shown in figure 3, external member 20 includes sleeve 23, width and the outer ledge of seal groove 14 to the side of connecting cylinder 11 of sleeve 23
The distance of edge is equal, and the side of sleeve 23 is provided with the screwed hole 22 being radially arranged along sleeve 23.
The inner diameter edge of sleeve 23 is provided with outward-dipping chamfering 24, and the edge of connecting cylinder 11 prolongs radially outward upset and formed
Bevelling, bevelling is connected with chamfering 24, and after mating connection, sleeve 23 can be stuck between bevelling and the seal groove 14 of protrusion,
So that sleeve 23 is difficult to drop；The radial outer edge of sleeve 23 is provided with intilted safe edge 21, plays good to workmen
Protective effect, it is to avoid scratch in operating process.
Screwed hole 22 near sleeve 23 outer ledge, the precession of bolt when not only improving processing, at the same can reduce again it is right
The damage of pipeline to be connected, additionally it is possible to fully ensure that connection tightness of the bolt to sleeve 23.The inner diameter edge of screwed hole 22 to
Sunken inside forms inner buckle groove, after bolt precession screwed hole 22 its edge can be made concordant with the edge of sleeve 23, junction surface
It is attractive in appearance and can effectively protect bolt.Screwed hole 22 is uniformly distributed so that the stress of pipeline to be connected is more balanced after installation.
In one embodiment, the number of screwed hole 22 and through hole is 3；In another embodiment, screwed hole 22
Number be 4, the number of through hole is 2 or 4.
Pipe fitting of the invention 10 and the non-casting of external member 20, while cost of material is reduced, simple production process, reduction
Production cost.
A kind of pipe connecting structure, including foregoing pipeline connecting assemble, sealing ring 30 and pipeline to be connected, two sections are treated
The connection end of connecting pipe is inserted into connecting cylinder 11, and the front end of pipeline to be connected contacts and extrude and is connected with connected unit 12.
Pipeline to be connected is tightly connected by sealing ring 30 with connecting cylinder 11, the screwed hole in screw bolt passes external member 20
22nd, the through hole on connecting cylinder 11 and tube contacts to be connected, and the top of bolt is connected with track squeeze to be connected.
Pipe connecting method of the invention, comprises the following steps：
Step 1：Prepare pipe fitting 10 and external member 20.
Step 2：External member 20 is enclosed within the two ends of pipe fitting 10, extruding the edge of pipe fitting 10 makes its outside bevelling, bevelling and set
The chamfering 24 of the inner diameter edge of part 20 is fitted.
Step 3：Sealing ring 30 is enclosed within the seal groove 14 of the inner side of pipe fitting 10.
Step 4：Two sections of pipelines to be connected are clamp-oned in pipe fitting 20, it is tightly connected by sealing ring 30 with pipe fitting 10.
Step 5：Bolt is aligned the through hole on the screwed hole 22 and pipe fitting 10 in external member 20, screwing bolts successively so that
The top plan of bolt and the flush with outer surface of external member 20, bolt inwardly extrude the outer wall of pipeline to be connected so that band connecting tube
Road is fixedly connected with pipe fitting 10.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
Exemplary description is carried out to patent of the present invention above in conjunction with accompanying drawing, it is clear that the realization of patent of the present invention is not received
The limitation of aforesaid way, if the various improvement that the method design of patent of the present invention and technical scheme are carried out are employed, or without
