Embodiment
The specific embodiment of the present invention is described with reference to the accompanying drawings.
Specific embodiment one
A kind of pipe joint sees figures.1.and.2, and its main structure comprises pipe joint 1 and connected tubing 2,3.This pipe joint 1 has a tube chamber, and has two connecting ends that are connected with tube chamber 11,12, is connected with tubing 2,3 respectively by this two connecting end 11,12, thereby makes tubing 2,3 realize connecting.
The following describes the linkage structure of connecting end 11 with the tubing 2 of pipe joint 1.
See figures.1.and.2, the connecting end 11 of pipe joint 1 forms a direct expansion section, and the madial wall of this direct expansion section is provided with internal thread, forms a gripping surface 10 between the madial wall of the madial wall of this direct expansion section and pipe joint 1 other parts.Other has a threaded connector 4, this threaded connector 4 is a sleeve shape body, be socketed on the periphery of tubing 2 connecting ends, the periphery wall of this threaded connector 4 is provided with the outside thread that matches with the internal thread of described pipe joint 1 connecting end 11 direct expansion section madial walls, and the end face of this threaded connector 4 in pipe joint 1 forms a gripping surface 40.The connecting end of tubing 2 outwards turns down, and forms flange 21, and this flange 21 is clamped between the gripping surface 40,10 of described threaded connector 4 and pipe joint 1, and the tube chamber of pipe joint 1 is connected with the tube chamber of tubing 2.
