As shown in Figure 1, be the sealed structural representation of steel pipe in the existing technology and sebific duct, the enlarged view that Fig. 2 locates for A ' among Fig. 1.As shown in the figure; Steel pipe 1 ' the end form annular protrusion 11 '; By the end inwardly be provided with annular retaining ring 12 ', wherein, annular protrusion 11 ' with steel pipe 1 ' the surface be the transition of R angle; Like this annular protrusion 11 ', R angle changeover portion and steel pipe 1 ' the surface form sealing surface; With sebific duct 2 ' be enclosed within steel pipe 1 ' go up and withstand on annular retaining ring 12 ' locate, clip 3 ' be fastened on annular protrusion 11 ' with the periphery of annular retaining ring 12 ' section sebific duct, realized steel pipe 1 ' with sebific duct 2 ' sealing be fastenedly connected.But the R angle changeover portion of said structure is prone between sebific duct and the steel pipe and pulls phenomenon, thereby cause the leakage of oil body, and reduces the working life of whole pipe fitting.
The model utility content
To above defective, the utility model provides a kind of structure that is tightly connected, through improvements over the prior art, strengthened the pulling-out force between steel pipe and the sebific duct, promoted both sealability and functional reliabilities, prolonged the working life of whole pipe fitting.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of structure that is tightly connected; Comprise steel pipe 1, sebific duct 2 and secure component 3; Form annular protrusion 11 in the end of steel pipe, inwardly be provided with annular retaining ring 12 by the end, the surface of annular protrusion 11 and steel pipe 1 is through the section of facing directly the transition perpendicular to steel pipe 1; Sebific duct 2 is enclosed within on the steel pipe 1 and withstands on annular retaining ring 12 places, and secure component 3 is locked at the periphery of annular protrusion 11 and 12 sections sebific ducts of annular retaining ring.
Preferably, secure component 3 withstands on the section of facing directly of annular protrusion 11 and steel pipe 1 transition.
Preferably, the height of the section of facing directly is not less than 0.3 millimeter.
Preferably, secure component 3 is clip or spring clip.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model; Through the changeover portion between annular protrusion in the existing technology and the steel pipe is improved; Changeover portion between annular protrusion and the steel pipe is improved to the section of facing directly the transition perpendicular to steel tube surface by the transition of R angle; Glue pipe socket at annular protrusion, face directly between changeover portion and the steel pipe on the formed sealing surface, and secure component withstood on face changeover portion directly sebific duct be connected and sealed, strengthened the pulling-out force between steel pipe and the sebific duct; Promote both sealability and functional reliability, prolonged the working life of whole pipe fitting.
