Pipe connecting structure for trampoline frame

摘要

A pipe connecting structure for trampoline frame includes a first pipe, a second pipe, and a coupling bar. The first pipe is provided at an end with a diameter-reduced portion having two diametrically opposite slots. The coupling bar is press-fitted in the diameter-reduced portion of the first pipe with an axial opening formed at its outer end in alignment with the two diametrically opposite slots on the first pipe. The second pipe is provided near an end for connecting to the diameter-reduced portion of the first pipe with a radially extended fixing pin. When the second pipe is connected to the diameter-reduced portion of the first pipe, the radial fixing pin is located in the two slots of the first pipe and the axial opening of the coupling bar to prevent the two pipes from circumferential movement relative to each other.
