Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are made further
Explanation, but this utility model is not limited to listed embodiment.
See Fig. 1～4b, a kind of buckle press joint overcoat, include:
Spacer shell 1, withholds on core pipe 4；
Shell 2, withholds on described spacer shell 1；
Four inner sleeves 3, described four inner sleeves 3 combine and are encapsulated in described shell,
It is equipped with annular tooth 31 on the internal chamber wall of each inner sleeve 3, the sidewall of described inner sleeve has
Docking port, docking port is that dislocation is placed, and described inner sleeve is squeezed and reduces rear described docking port
Face, two butt ends docking, the cannelure 41 that described annular tooth is corresponding with on described core pipe
Mutually extruding coordinates the body being placed between described inner sleeve 3 and core pipe 4 to fasten compression.
Tighter in order to realize fastening, prevent body from fastening retrolisthesis and realizing better seal
Function, i.e. anticreep pull out sealing function, and the height of described annular tooth 31 is from described body
The inboard installing lateral described spacer shell in gradually rising trend or installation side end face the
One tooth is shallow, and the tooth of the inside is contour.
Further, described annular tooth 31 is opened on the internal chamber wall of described inner sleeve.
Described annular tooth can be arc double wedge, and two bottom sides has corresponding tapering, institute
Stating the gap 3-7mm between annular tooth, the both sides cone angle of described annular tooth is 10-30 degree,
The height of described annular tooth is 1.5-3mm.
Further, two docking end face 32,33 tools of the docking port of described inner sleeve 3
There is corresponding dislocation docking structure, it is also possible to be structure as similar straight channel type joggle
Deng, concrete shape does not limits.
Further, the inwall of described spacer shell 1 has and the transition on described core pipe 4
The ledge structure 12 that set stopper slot 41 matches.Implementing, described spacer shell limits
Position groove 41 is cannelure, and described ledge structure 12 is located at the inwall of described spacer shell for ring
On face, and it is connected with described spacer shell stopper slot 41 interference fit.
Implementing, the outer wall of the inboard end of described spacer shell 1 is cone-shaped structure
14, body to be withheld inserts and coordinates, and the inwall of inboard end is the conical surface 15 and core
On pipe, the corresponding medial extremity of spacer shell stopper slot 41 matches, outside described spacer shell 1
The end face of dew end is arc angling transition structure 13 with the outer wall place of joining.Described Step-edge Junction
Structure 12 is right angle step.
Further, described shell 2 includes spacer shell buckling parts 21 and inner sleeve encapsulation
Portion 23, described spacer shell buckling parts is connected by rake 22 with inner sleeve encapsulation part.Tool
Body realize on, the two ends of described rake 22 respectively by the first curved transition sections 25 with
And second curved transition sections 26 and described spacer shell buckling parts and described inner sleeve encapsulation part
23 transition connect.
In order to realize dropping after described inner sleeve is packaged in described shell, further, institute
The outboard end stating inner sleeve encapsulation part 23 has the infolding position-limited edge preventing described inner sleeve from dropping
24.Implementing, described infolding position-limited edge 24 is after in 90 degree of infoldings, and it is certainly
Form the free end of a hook-like again to infolding certain angle by end.So it is easier to
Realize the function of the spacing Anti-fall to described inner sleeve.
It is fastened and connected fixing in order to realize described shell with described spacer shell, further,
The outside wall surface of described spacer shell 1 has shell buckling groove 11, the buckling parts of described shell
21 have the fastening convex surface 21 being interlocked with described shell buckling groove 11.
Further, the outer wall of described inner sleeve 3 contacts with the inwall of described shell 2 and is connected.
So so that inner sleeve is more stable with the connection of described shell, coordinate when extruding more preferably,
Certain gap can certainly be reserved.
Buckle press joint overcoat of the present utility model is owing to using by spacer shell, inner sleeve, shell
Three independent sectors are constituted, and are adding man-hour, and three independent sectors are individually processed, and
Spacer shell relatively easy can Vehicle Processing, single inner sleeve can use heavy-gauge sheeting by above-mentioned structure
Draw dial shape, then punching press cut off after Rolling, combine be encapsulated in described outside
In shell, shell uses sheet metal stretch forming, and three-piece carries out plate surface process respectively.
Spacer shell, shell and the inner sleeve of buckle press joint overcoat of the present utility model, especially
It is shell and single inner sleeve only needs punch press to process, may be designed to the progressive die and produce, this
Sample is more readily formed batch sizes, and production efficiency is the highest, low cost, and quality is more
Good control.
Buckle press joint overcoat of the present utility model when mounted, first withholds spacer shell at core pipe
On, then withhold shell outside spacer shell, single inner sleeve is sequentially loaded in shell, to shell
End face carries out in-flanges process, and inner sleeve is closed in shell.
When withholding flexible pipe, shell is directly withheld by buckle machine, while shell contracting shell,
Inner sleeve starts to shrink at, and indentation, there is docked by the dislocation docking structure on both sides, works as button
It is pressed onto when requiring size, just inner sleeve synthesis one complete circle, the simultaneously internal face of inner sleeve
On annular tooth and core pipe on fit depressions jointly catch body, such as flexible pipe, thus
Formed and seal and anti-dial de-function.
The overcoat of this utility model buckle press joint is owing to including spacer shell, shell, inner sleeve
Three parts, and described inner sleeve is the split type inner sleeve having docking port on sidewall so that
The processing of the annular tooth of inner sleeve becomes very simple, and the molding reducing processing annular tooth is difficult
Degree, decreases processing cost, is greatly enhanced the efficiency of the making of buckle press joint overcoat,
Batch large-scale production can be realized, there is great production practices and realistic meaning.
The above, the only preferred embodiment of this utility model technology, this utility model
The scope of technical protection is not limited thereto, and any people being familiar with this technology is new in this practicality
It is appreciated that the conversion expected or replacement in scope disclosed by type, all should contain in this practicality
Novel comprise within the scope of, therefore, the protection domain of this utility model technology should be with
The protection domain of claims is as the criterion.
