[0019] The utility model provides a technical solution: Figure 1 and Figure 2As shown, in the present embodiment, a trampoline guard net rod connection structure comprises a connecting sleeve 2 arranged at the bottom of the guard net rod 1, a limiting plate 3 is symmetrically arranged inside the connecting sleeve 2, a telescopic spring 4 is installed between the two limiting plates 3, limiting protrusions 6 are symmetrically fixed on the side bottom surfaces of the two limiting plates 3, and a through groove 7 for the limiting protrusion 6 to engage is symmetrically opened on the inner wall of the connecting sleeve 2, the surface diameter of one end of the limiting protrusion 6 is smaller than the inner diameter of the opening of the through groove 7, and the side surface of one end of the limiting protrusion 6 is an inclined surface, and the end surfaces of the two limiting plates 3 are fixed with mounting plates 5, the surface diameter of the mounting plate 5 is equal to the inner diameter of the opening of the connecting sleeve 2, and the surface of the mounting plate 5 is welded and fixed to the surface of the limiting plate 3, so that the guard net rod 1 can be mounted on the bed frame, which is convenient and quick to operate, and fixed installation can be achieved without using bolts, which is convenient to improve the installation efficiency of workers and has good practicality.

[0020] like Figure 3 and Figure 4 As shown, a limit pin 8 is symmetrically arranged on the outer side of one end of the connecting sleeve 2, an elastic band 9 is fixed to the middle of the surface of one end of the limit pin 8, a fixing ring 10 is symmetrically installed on the outer side surface of one end of the connecting sleeve 2, one end of the elastic band 9 is knotted on the outside of the fixing ring 10, a first limit hole 11 is symmetrically opened on the outer side surface of one end of the connecting sleeve 2, and a second limit hole 12 is symmetrically opened on the side surface of one end of the protective net rod 1, the opening of the first limit hole 11 is opposite to the opening of the second limit hole 12, and one end of the limit pin 8 passes through the first limit hole 11. Inside the positioning hole 11 and the second positioning hole 12, the cross-section of the limiting pin 8 is "T"-shaped, and the side surface of one end of the limiting pin 8 is tightly fitted with the inner wall of the first limiting hole 11 and the second limiting hole 12. The inner wall of the end of the connecting sleeve 2 is symmetrically provided with a fixing ring groove 13, and a limiting ring 14 is fixed inside the fixing ring groove 13.
