ABSTRACT:
An improved umbrella rod structure of multiple tubes, in which the locating assembly includes a spring, a main body, and a plunger. The locating assembly is plugged into an inner tube, with a stop flange of the main body abutting against the lower end of the inner tube. Then, the conical front end of the plunger will retractably project out of a through hole of the inner tube. Using the recessed groove of the outer tube sliding over the elongated guide groove of the inner tube, the projecting end of the plunger will first engage with the lower aperature of the outer tube and then as the inner tube is drawn upwards to have a short rib of the main body abut against the upper segment of the recessed groove, which has a smaller curvature, the plunger will engage with the upper aperature to lock the inner tube and the outer tube in position. With such an arrangement, the inner tube and the outer tube can cooperate with each other to open or close an umbrella, without relative rotation motion therebetween.
