As the further improvement of the utility model, the length of said first reinforced pipe is greater than the length of said the 3rd reinforced pipe, and the length of said second reinforced pipe is greater than the length of said the 4th reinforced pipe.
As the further improvement of the utility model, said first reinforced pipe and said the 3rd reinforced pipe are linearly.
As the further improvement of the utility model, the angle of adjacent two reinforced pipes is spent less than 180 greater than 0 degree.
As the further improvement of the utility model, the both ends open of said circular ball seat on the vertical line direction on plane, said reinforced pipe place.
Further improvement as the utility model; Said circular ball seat is provided with four water holes that disappear; Lay respectively at the weld of said circular ball seat and said first reinforced pipe, second reinforced pipe, the 3rd reinforced pipe, the 4th reinforced pipe, and the said water hole that disappears is connected with said reinforced pipe.
As the further improvement of the utility model, said circular ball seat is respectively equipped with end cover rubber on the both ends open on the vertical line direction on plane, said reinforced pipe place.
The beneficial effect of the utility model is: the utility model is to triangle moulding (X type pipe fitting overlap joint) before the specific vehicle frame; Use the transfer overlap joint of pipe fitting and pipe fitting of circular ball seat, can disperse the stress of pipe fitting and pipe fitting overlap joint, improve vehicle frame testing fatigue result; Circular ball seat both ends open; And be processed with the larger-size water hole that disappears, and assembler can be through the trend of cabling in the openings at two ends guiding tube, and cabling is convenient; Circular ball seat both ends open used end cover rubber to block up after cabling was accomplished, and is both artistic and practical.
