Abstract

The invention relates to the technical field of well lids, in particular to a quick opening and closing type urban highway well lid with a fallen object collecting structure. The quick opening and closing type urban highway well lid comprises a fixing frame, the fixing frame is arranged to be annular, a water drum is welded to the lower end of the fixing frame, an auxiliary drainage hole is formedin the water drum, a lid groove is formed in the upper end of the fixing frame, a lid body is installed in the lid groove, four sets of limiting grooves are formed in the edge of the lid body at equal intervals, screw rods are transversely installed in the four sets of limiting grooves through bearings, and a transmission mechanism is arranged at the ends, close to each other, of the four sets ofscrew rods. The transmission mechanism is arranged to control a locking mechanism, a rotating handle at the output end of the transmission mechanism is detachable, so that all lid bodies of the sametype are controlled through the single rotating handle, the locking mechanism is difficult to open if the rotating handle is not used, the locking mechanism can firmly lock the lid bodies and the fixing frame, and thus the stabilizing and anti-theft effects are achieved.
