Abstract
The utility model discloses a stroller frame which comprises pushing handles, a connecting seat, two rear wheel supports, two cross-shaped support rods, two front wheel supports and a front wheel support connecting rod. When the stroller frame is unfolded, the two cross-shaped support rods stand up and can stably support the handles on both sides and the two rear wheel supports under the action of the traverse rod and the front wheel supports. When the stroller frame is folded, the handheld parts at the upper end of the pushing handles rotate forwards relative to the front wheel supports, and the lower parts of the pushing handles rotate backwards, so that the two cross-shaped support rods rotate downwards and backwards relative to the rear wheel support; the two front wheel supports rotate downwards and move close to the rear wheel supports along with the front wheel support connecting rod, so that the two cross-shaped support rods move from the horizontal position to the vertical position and are folded up at the same time, as a result, the two rear wheel supports are folded up and enable the pushing handles to be folded up towards the inner side of the stroller frame. The folded stroller frame has less size along the transverse direction and is easy to store and carry.
