Embodiment
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Refer to figure, a kind of buckle press joint overcoat, includes:
Spacer shell 1, withholds on core pipe 4;
Shell 2, withholds on described spacer shell 1;
Inner sleeve 3, be encapsulated in described shell 2, the internal chamber wall of described inner sleeve 3 is provided with multiple annular tooth 31, the sidewall of described inner sleeve has docking port, described inner sleeve is squeezed face, two butt ends docking reducing rear described docking port, and the described annular tooth circular groove 41 corresponding with on described core pipe be mutual to be extruded to coordinate the body be placed between described inner sleeve 3 and core pipe 4 to fasten and compress.
Tighter in order to realize fastening, prevent body from fastening retrolisthesis and realizing better sealing function, namely anticreep pulls out sealing function, the height of described annular tooth 31 from the installation side of described body to the inboard of described spacer shell in raising trend gradually.
In specific implementation, described annular tooth 31 is opened on the 4-6 internal chamber wall of described inner sleeve.
Described annular tooth can be arc double wedge, and two bottom sides has corresponding tapering, the gap 3-7mm between described annular tooth, and the both sides cone angle of described annular tooth is 10-30 degree, and the height of described annular tooth is 1.5-3mm.
Further, shown in Fig. 4 b, 4c, two docking end faces 32,33 of the docking port of described inner sleeve 3 have corresponding dislocation docking structure 34, and also can be structure like similar straight channel type joggle etc., concrete shape not be limit.
Further, the inwall of described spacer shell 1 has the ledge structure 12 matched with the spacer shell restraining groove 41 on described core pipe 4.In specific implementation, described spacer shell restraining groove 41 is circular groove, on the internal face that described ledge structure 12 is ring is located at described spacer shell, and is connected with described spacer shell restraining groove 41 interference fit.
In specific implementation, the outer wall of the inboard end of described spacer shell 1 is cone-shaped structure 14, body conveniently to be withheld inserts and coordinates, the inwall of inboard end is that the conical surface 15 matches with the corresponding medial extremity of spacer shell restraining groove 41 on core pipe, and end face and the outer wall place of joining of the exposed junction of described spacer shell 1 are arc angling transition structure 13.Described ledge structure 12 is right angle step.
Further, described shell 2 comprises spacer shell buckling part 21 and inner sleeve encapsulation part 23, and described spacer shell buckling part is connected by rake 22 with inner sleeve encapsulation part.In specific implementation, the two ends of described rake 22 are connected with described spacer shell buckling part and the transition of described inner sleeve encapsulation part 23 respectively by the first curved transition sections 25 and the second curved transition sections 26.
Be packaged in after in described shell drop to realize described inner sleeve, further, the outboard end of described inner sleeve encapsulation part 23 has the infolding position-limited edge 24 preventing described inner sleeve from dropping.In specific implementation, described infolding position-limited edge 24 is after being 90 degree of infoldings, and its free end forms the free end of a hook-like again to infolding several angle.So more easily realize the function of the spacing Anti-fall to described inner sleeve.
In order to realize described shell and described spacer shell is fastened and connected fixing, further, the outer wall of described spacer shell 1 has shell buckling groove 11, and the buckling part 21 of described shell has the fastening convex surface 21 be 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.Like this, make the connection of inner sleeve and described shell more stable, coordinating when extruding better, certain gap can certainly be reserved.
Buckle press joint overcoat of the present invention is made up of spacer shell, inner sleeve, shell three independent sectors owing to adopting, adding man-hour, three independent sectors are individually processed, and spacer shell relatively simply can Vehicle Processing, inner sleeve can adopt heavy-gauge sheeting to draw by above-mentioned structure and dial shaping, then rear Rolling is cut off in punching press, and shell adopts sheet metal stretch forming, and three-piece carries out plate surface process respectively.
The spacer shell of buckle press joint overcoat of the present invention, shell and inner sleeve, particularly shell and inner sleeve only need punch press to process, and can be designed to the progressive die and produce, so more easily form batch sizes, manufacturing efficiency is very high, and cost is low, and better quality controls.
Buckle press joint overcoat of the present invention when mounted, is first withheld spacer shell on core pipe, then is withheld shell outside spacer shell, and inner sleeve loads in shell, carries out in-flanges process, inner sleeve is closed in shell to shell end face.
When withholding flexible pipe, buckle machine is directly withheld shell, while shell contracting shell, inner sleeve start shrink, indentation, there is docked by the dislocation docking structure on both sides, when withhold require size time, just in time inner sleeve synthesizes a complete circle, annular tooth on the internal face of simultaneously inner sleeve catches body jointly with the fit depressions on core pipe, as flexible pipe, thus is formed and seals and anti-dial de-function.
The overcoat of buckle press joint of the present invention is owing to including spacer shell, shell, inner sleeve three parts, and described inner sleeve is, the processing of the annular tooth of inner sleeve is made to become very simple, reduce the difficulty of processing annular tooth, decrease processing cost high, greatly improve the efficiency of the making of buckle press joint overcoat, batch mass production can be realized, there is great production practices and realistic meaning.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
