Embodiment
Below in conjunction with Figure of description, the invention will be further described with concrete preferred embodiment.
embodiment 1:
Fig. 1 to Fig. 5 shows the first embodiment that tubing of the present invention is fastenedly connected accessory, these connection fittings comprise swelling joint 1 and for making the jackscrew 2 of swelling joint 1 distending, swelling joint 1 comprises connecting bottom board 11, connecting bottom board 11 lower ends are bent with raising plate 12, connecting bottom board 11 both sides are bent with two blocks of side plates 14, two side plate 14 upper ends are equipped with the top board 13 that is bent to connecting bottom board 11 tops, jackscrew 2 one end are threaded with raising plate 12, the other end and two top boards 13 join, while screwing jackscrew 2, the downward distending of raising plate 12, top board 13 is distending upwards, and drive two blocks of side plates 14 to be connected with tubing 3 inwalls formation four sides swellings to both sides distending, it is simple in structure, be convenient to install, can effectively protect fastening piece not impaired.During assembling, first by fastening piece, swelling joint 1 and tubing 3 outer walls are fastenedly connected, again by jackscrew 2 precession swelling joints 1, and one end of jackscrew 2 and two top boards 13 of swelling joint 1 are joined, then another tubing 3 is inserted in to the outside of swelling joint 1, the perforate of passing this tubing 3 with instrument continues to screw jackscrew 2, make the downward distending of raising plate 12, two top boards 13 are distending upwards, and drive two blocks of side plates 14 to be connected with these tubing 3 inwalls formation four sides swellings to both sides distending, when two sections of tubing 3 are damaged power, the power that these connection fittings bear is not concentrated on jackscrew 2, but offset by the tension force between swelling joint 1 and tubing 3 inwalls, thereby can prevent jackscrew 2 to be subject to shearing force and rupture, avoid the Joint failure of two sections of tubing 3.
