The whole process is through the cooperation of a linkage mechanism, and the folding is smooth. After the folding is completed, the volume is small and easy to carry. Moreover, during the folding process of the stroller, the first hinged part on the push rod and the second hinged part on the front connecting rod rotate relatively, and when the stroller is in the folded position, the projection on the first hinged part snaps into place. into the slot on the second hinge, so that the stroller remains stable in the folded state, and due to the cooperation between the protrusion and the slot, there are fewer parts and the cost is reduced. When the baby carriage needs to be unfolded, it is only necessary to turn the hand push rod firmly to disengage the protrusion from the card slot, and the operation is also very convenient.

2. When the utility model is folded, the lower end of the hand push rod moves backward and downward, and during the process of driving the upper end of the rear connecting rod and the upper end of the front connecting rod to move downward, the seat frame rod slides in the sliding sleeve, and the rear connecting rod When the upper end moves downward, the lower end of the rear connecting rod tilts up obliquely, and the linkage rod is pulled during the tilting process, so that the front legs are pulled closer to the rear legs through the linkage rod. The entire traction and folding assembly is ingeniously designed and simple in structure , so that the stroller can be folded smoothly, and the folded size is small.

3. The front connecting rod of the utility model is provided with a connecting seat, between the lower end of the connecting seat and the seat frame rod, there is a lower armrest link hinged with the two, and the upper end of the connecting seat is provided with an upper armrest link connected to it in rotation. A U-shaped handrail is detachably connected to the upper link of the handrail. Therefore, when the stroller is folded, the front armrest can be folded along with it, without disassembling the front armrest, and the operation is very fast.

4. The utility model has simple structure and low cost, and is suitable for popularization and application.
