A frame pipe connecting structure for a trampoline includes two frame pipes (1), a foot pipe (5), a guardrail pipe (7), a three-way component (2), bolts (8) and nuts (9); the foot pipe (5) longitudinally inserts into the vertical pipe portion of the three-way component (2); the frame pipes (1) insert into the horizontal pipe portion of the three-way component (2) from its two ends and sleeve together; a positioning groove (6) and hole-shaped protrusions (4) are provided on the three-way component (2), and a positioning slot is provided on the frame pipe (1); bolt holes (3) are respectively provided on the three-way component (2), the guardrail pipe (7) and the foot pipe (5); the foot pipe (5) inserts into the vertical pipe portion, then the bolts (8) pass through the bolt holes (3) and are fastened by the nuts (9), thereafter the bolts (8) pass through the bolt holes (3) on the guardrail pipe (7) and are fastened by the nuts (9); the positioning groove (6) is embedded into the positioning slot to be located, and the hole-shaped protrusions (4) are wedged into the connecting holes in the frame pipes (1) to make them fastened together. The frame pipe connecting structure for a trampoline has the following advantages: free of welding, a simple structure, material saving, convenient loading and unloading, improved efficiency, convenience of conveying and storing, higher strength, lower possibility of shake, skid and the damage of the combined portion; and the trampoline adopting the frame pipe connecting structure is more safe and artistic.
