Abstract
It is the quick coupling device being directed between the pipeline that working medium is gas or liquid, including sub- end, female end, clamp spring and sealing ring the present invention provides a kind of pipeline fast joint structure.The present invention realizes quickly connecting and sealing between pipeline, is widely used in a variety of industrial circles.
Description
Technical field
The invention belongs to industrial pipeline technical fields, more particularly, to a kind of pipeline fast joint structure.
Background technology
Often with settling mode it is flanged joint or intubation connection type when industrial pipeline connects, wherein flange connection,
Flange is needed to see that bolt fastens；Intubation connection type is also required to clip and bolt fastening.Both modes are required to bolt, and
It is needed by tools such as spanners when installation, installation effectiveness is low, and the time is long, cannot meet some coupling parts for needing to be rapidly completed
It needs.
Invention content
In view of this, the present invention is directed to propose a kind of pipeline fast joint structure, to improve installation effectiveness.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of pipeline fast joint structure, including：
Sub- end is tube-shaped structure, and one end is used for connecting line, and the other end is connected with the female end, is connected with female end
Section is equipped with the annular projection with Fillet Feature, and raised both sides are straight pipe；
Female end is maximum inner diameter section for connexon end side to become the round tube shape structure of internal diameter, and maximum inner diameter is more than son
End ring shape protruding apex diameter value, the inside diameter ranges of the connected small internal diameter section of maximum inner diameter section are in sub- end ring shape protruding apex diameter
Between value and sub- end protrusion both sides straight pipe outer diameter value, the lateral surface of maximum inner diameter section is equipped with multiple radial through-holes, multiple
Through-hole center is located at the same plane vertical with axis；
Clamp spring is petal-shaped not closing structure, and the part to concave can be smoothly embedded in the through-hole of female end；
Sealing ring, after group end is inserted into female end, sealing ring is arranged between annular projection inner end and female end internal diameter end face.
Further, the through-hole of the female end be located at group end be inserted into female end after when annular projection outer end corresponding position
Place.
Further, the clamp spring is three petal-shaped structures, is not closing structure at one of petal.
Compared with the existing technology, the present invention has the advantage that：
The configuration of the present invention is simple realizes quickly connecting and sealing between pipeline, is widely used in a variety of industrial circles.

Specific implementation mode
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
A kind of pipeline fast joint structure of the embodiment of the present invention, as shown in Figures 1 to 4, including：
Sub- end 1 is tube-shaped structure, and one end is used for connecting line, and the other end is connected with the female end 2, with 2 phase of female end
Even section is equipped with the annular projection with Fillet Feature, and annular projection both sides are straight pipe；
Female end 2 is maximum inner diameter section for connexon end side to become the round tube shape structure of internal diameter, and maximum inner diameter is more than
The inside diameter ranges of sub- end ring shape protruding apex diameter value, the connected small internal diameter section of maximum inner diameter section are straight in sub- end ring shape protruding apex
Between diameter value and sub- end protrusion both sides straight pipe outer diameter value, the lateral surface of maximum inner diameter section is equipped with multiple radial through-holes, more
A through-hole center is located at the same plane vertical with axis；
Clamp spring 3 is three petal-shaped not closing structures, and one of petal middle is not closed position, is concaved
Part can be smoothly embedded in the through-hole of female end 2, and through-hole is clamp spring entrance 7；
Sealing ring 4, after group end 1 is inserted into female end 2, sealing ring 4 is arranged in annular projection inner end and 2 internal diameter end face of female end
Between.
The through-hole of the female end 2 be located at group end 1 be inserted into female end 2 after when annular projection outer end clamp spring contact surface 6 it is right
It answers at position.
When pipeline fast joint structure application of the present invention：
After group end 1 is inserted into female end 2, being nested in 3 female parts of clamp spring of 2 through-hole of female end will be stuck in outside 1 protrusion of sub- end
End, sub- end 1 and female end 2 is fixed together, while being sleeved on the sealing ring 4 of the sealing ring contact surface 5 of 1 annular projection inner end of sub- end
It will be contacted with the end face of female end 2, realize sealing.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
