Abstract

The utility model relates to a height adjustment structure for a baby walker. As two gear racks are fixed on left and right both ends at the bottom side of a top frame, the length of the gear racks can be increased, and the numbers of pawls on the gear racks can be increased. Not only the height of the baby walker can be adjusted lightly, but also the height of the baby walker can be adjusted to higher or lower. Thereby, infantile feet can properly touch down. A front frame of the height adjustment structure for a baby walker is sheathed with the gear racks by two shrinking blocks on the right and the left ends of a transverse rod to assemble with the top frame. Thus, the weight that the top frame is pressed down can be shared out equally on both ends of the transverse rod of the front frame, and the transverse rod can not be deformed. In addition, when the height of the baby walker needs to be raised, only the top frame is directly pulled upward to adjust. Thus, the adjusting operation of the utility model is simple.
