ROTARY JOINT STRUCTURE AND BABY TROLLEY WITH THE SAME

摘要

A baby trolley is provided. A side frame of each side comprises a front frame (2), a pusher frame (1) whose lower end is rotatably connected with the front frame via a shaft (15). At the upper part of the front frame, there is an extension part (16) upward from the shaft. The extension part can prevent the pusher frame from passing the extension part to rotate backward. The extension part and the lower part of the pusher frame form an angle (17), whose vertex is the shaft and whose open-end is upward. The trolley frame also comprises a protection part (3). The protection part has a left protection wall (6) and a right protection wall (7) which are provided on the left and right sides of the angle separately. During the rotation of the pusher frame relative to the front frame, the left protection wall and right protection wall keep on the left and right sides of the angle as a barrier and prevent the baby from putting the finger into the angle from the left and right side of the angle. Because of adding the protection part with the left and right protection wall, the finger of baby will not reach into the angle from the left or right side of the angle so as to avoid clipping fingers.
