Abstract

A stroller for infants, the stroller frame includes a first rod, a second rod that is rotatably connected to the first rod at one end through a third rotating shaft, and the rod body of the second rod is along the axis of the third rotating shaft The direction extends outward to form an extension. When the cart frame is in the unfolded position, one side of the extension is against the rod body of the first rod. When the cart frame is in the folded position, the other side of the extension part against the rod body of the first rod. Because when the pushcart frame is in the unfolded position, one side of the extension part abuts on the rod body of the first rod, so the part of the second rod does not overlap with the first rod, eliminating the hidden danger of shearing, and through The extension part can meet the requirement of rigidity, and there is no need to press the lower end of the push rod against the first rod in the unfolded position, and the injury caused by the pressure of the lower end of the push rod is eliminated, so it is safer to use.

Description

toddler stroller

technical field

The utility model relates to a child stroller.

Background technique

A baby stroller, comprising a stroller frame with an unfolded position and a folded position, wheels arranged at the lower part of the stroller frame, and a locking device for locking the stroller frame at the unfolded position, The cart frame includes a first rod, a second rod whose one end is rotatably connected to the first rod through a third rotating shaft, and whose lower part is connected to the other end of the second rod. Rotate the connected push rod, the second rod is usually a connecting piece, the connecting piece is relatively thin, when the cart frame is in the unfolded position, the part of the connecting piece and the first The rods are overlapped, relying on the contact between the lower end of the push rod and the rear bracket to form a rigid support point.
