In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Fig. 1 is the stereoscopic schematic diagram according to the pipe coupling component of the utility model one embodiment.Pipe coupling component is general
It may include property connector 1, pipe 2, sealing ring 3 and nut 4.
Wherein the end circumferential surface of connector 1 is provided with external screw thread 11, and 11 root of external screw thread is provided with flange 12, and flange 12 rises
To barrier effect, prevent nut 4 from excessively advancing.12 periphery of flange is set as hexagon and is held with convenient wrench.
Pipe 2 is conventional tubulose, and the front end circumferential surface of pipe 2 is provided with a circle annular protrusion 21, before annular protrusion 21 and pipe 2
End is a distance away.
As shown in Fig. 2, annular protrusion 21 is formed by a bit of squeeze from inside to outside of pipe 2.Particular by research and development equipment
The molding die of machine achievees the effect that pipe 2(steel pipe) it is preforming.Annular protrusion 21 is made of cold forming mode, pipe 2 it is cold at
Type is completed by E02-FORM machine.Cold forming pipe can be simply and quickly made in E02-FORM machine, i.e., with annular protrusion 21
Pipe 2.
Sealing ring 3 is arranged between connector 1 and pipe 2, and sealing ring 3 is placed on the front end of pipe 2 and slides into and annular protrusion
21 offset, and one side of the sealing ring 3 towards connector 1 offsets with connector 1.
Such as Fig. 2, nut 4 is placed on 2 periphery of pipe, and the front end inner peripheral surface of nut 4 is provided with internal screw thread 42.In internal screw thread 42
The internal diameter of root position nut 4, which reduces to be formed, shrinks step 41.Step 41 is shunk to be pushed against on annular protrusion 21 relative to sealing
