Description

Convertible Seat Mechanism for Stroller

technical field

The utility model relates to a convertible seat pocket mechanism of a baby carriage.

Background technique

At present, there are many fashionable and beautiful baby carriages on the market, but because their bases are fixed on the frame and cannot be disassembled, for example, one kind of baby carriage is equipped with a basket, while the other kind of baby carriage is equipped with a chair. In different situations, babies can only use the same seat and cannot be replaced. Therefore, at different stages of infant growth, as the child's height and needs change, each family must replace baby carriages with different functions. Meet your child's needs. This is not only a waste of raw materials and resources, which is not conducive to environmental protection, but also increases a certain economic burden for the family.

In order to solve the above problems, some existing baby carriages design both the chair and the basket as a structure that can be plugged and installed with the frame, and the conversion of the two functions can be realized by replacing the chair or the basket. Although this design reduces the cost to a certain extent , but it still needs to be equipped with a chair and a basket for a frame, the cost is still not low, and it cannot be replaced in real time as needed. The replacement can only be realized when the two accessories are available at the same time. It is obviously impractical to replace the carrying basket with a chair or the chair with a basket when going out. Therefore, even if two accessories are equipped, they cannot be replaced at any time, so they cannot better meet the needs of children.
