[0041] It should be noted that the height adjustment device includes an adjustment seat, which is equipped with an adjustment platform and a drive platform. The adjustment seat is slidably installed in a guide groove on the back of the cover plate, and the drive platform pushes the adjustment seat to slide along the guide groove. When the height of the baby walker needs to be adjusted, the drive platform slides backward along the guide groove, disengaging the adjustment platform from the adjustment groove on the support frame. The adjustment platform can then be aligned with the appropriate adjustment groove according to the child's height. After selecting the appropriate height, the drive platform slides forward along the guide groove, engaging and locking the adjustment platform with the adjustment groove.

The locking pin extends into the locking groove for sliding. The locking groove is distributed in a gourd shape, with the diameter of its two ends being larger than the diameter of its middle section, and the diameter of its middle section being smaller than the diameter of the locking pin. Therefore, whether the adjustment table is connected to or separated from the adjustment groove, the locking pin can be stably locked in the locking groove, ensuring stability after adjustment or during adjustment. This ensures that the height of the walker will not accidentally slide due to external forces, guaranteeing the safety of children during use and enhancing the reliability of the walker.

[0043] To enhance the playability of the baby walker, a spring is installed between the base and the support frame. One end of the spring presses against the support frame, while the other end presses against the base. When the adjustment platform is unlocked and separated, the support frame can be elastically supported on the base through the spring. At this time, the spring is compressed and extended according to the child's movements, which makes the child feel a bouncing sensation, increasing the fun of the baby walker and avoiding the discomfort caused by traditional rigid support. This stimulates children's interactive interest in the process of learning to walk, making it more attractive and entertaining.

[0044] The support frame and panel can be quickly disassembled and assembled. The bottom of the panel has a mating groove with locking holes on both sides. The top of the support frame has a mating seat containing a locking pin and a locking block. By vertically pulling the locking block, the locking pin engages or disengages from the locking holes, enabling quick disassembly and assembly of the support frame and panel. This facilitates the storage and transportation of the walker, improves its ease of use, and therefore allows for widespread adoption.
