Abstract

The utility model discloses a foldable children stroller, which comprises a stroller frame with an unfolding state and a folding state, a front wheel and rear wheels and a locking device, wherein the front wheel and the rear wheels are installed below the stroller frame, and the locking device is used for locking the stroller frame in an unfolding state. The stroller frame comprises a front support rod, rear support rods, push rods, seat armrests, connection rods and a seat rod. The foldable children stroller has the advantages that the push rods are pushed downwards along the length direction after the locking device of the stroller is unlocked when the stroller is folded, and the push rods slide so as to enable the stroller to contract in height. The push rods drive the seat armrests to rotate while sliding downwards and further drive the connection rods to rotate, the connection rods drive the seat rod to rotate, and the seat rod drives the rear support rods to rotate and fold towards the front support rod, thereby enabling the stroller to be contracted in thickness. When the stroller is unfolded, the operation is opposite.
