Abstract

The invention discloses a structure of a baby stroller in which a bending handle is integrally retracted, comprising: a stroller frame with two states of unfolding and folding; a fixed joint is installed on the top ends of both sides of the stroller frame; a fixed joint The bottom end of the handlebar tube is installed by rotating and inserting upward, and the top end of the handlebar tube is connected with a bending device. When the cart frame is in the unfolded state, the limit boss set on the bottom side wall of the handlebar tube is connected with the fixed joint. The top port wall is in contact with the limit. When the cart frame is in the folded state, the bending device bends and drives the handle tubes on both sides to rotate. At the corresponding position of the groove, the handle tube slides down and closes along the fixed joint. By adopting this technical solution, the folding and folding of the cart frame is realized by the bending device driving the handle tube to bend and rotate, and the folding operation of the cart frame is convenient. Pull the handle tube upward to the limit state.
