Abstract
The invention relates to a folding baby trolley, including a trolley frame, trolley wheels arranged at the lower part of the trolley frame and a locking mechanism arranged on the trolley frame, wherein, the trolley frame includes two side brackets symmetrically arranged at both sides of the trolley frame and a horizontal connecting rod which connects the two side brackets horizontally. Each of the side brackets includes a push rod, a side handrail, a front wheel bracket, a rear wheel bracket, a cushion rod, a backrest connector and a folding connecting rod. A guiding groove which extends along the lengthwise direction of the rear wheel bracket is opened on the rear wheel bracket. As the folding connecting rod is added to the trolley frame and the guiding groove is opened on the rear wheel bracket for the slide of the backrest connector, thereby leading the trolley frame to be more compacter after being folded and saving room.
