Description

Technical Field

[0001] The invention relates to a foldable baby carriage technology, in particular to a rotatable and foldable seat pocket structure and a baby carriage using the structure. Background Art

[0002] A baby stroller is a tool vehicle designed to facilitate outdoor activities for babies. It is also the baby's favorite means of transportation for walking and a necessity for mothers to take their babies shopping. However, according to the baby's growth and usage, baby strollers can be divided into many types, mainly based on the load capacity. The general test standard is nine to fifteen kilograms. The general baby stroller can be used for about four to five years.

[0003] At present, the existing baby strollers still have shortcomings. Most baby strollers cannot be folded or only have a simple folding function when in use, and the volume of the baby stroller cannot be more thoroughly compressed, resulting in the baby stroller occupying a large volume when carried in a vehicle or when the baby stroller is not in use, and is not convenient for storage; in addition, although some frames of existing baby strollers can be folded, the seat pocket part for children to sit on is a fixed mode, which can neither be folded to save space nor reduce the flexibility of children when sitting, causing children to maintain the same posture for a long time, which is not conducive to children's riding;

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When using this baby stroller, if the child needs to see the scenery in front, the seat pocket can be facing forward. If due to weather reasons, such as when the sun is too strong or there is wind and sand, the child's seat pocket can be adjusted to the rear to increase the child's comfort when riding. When adjusting the seat pocket group, press the pedal adjustment button to rotate the pedal upward, and then the seat pocket group can be rotated so that the seat pocket group rotates above the seat pocket chassis group and rotates to the rear, and then the pedal group is lowered to a drooping state, the direction of the seat pocket group can be re-locked, and the adjustment of the seat pocket group is completed. Not only does it realize the on-demand adjustment of the seat pocket direction and increase the child's comfort when riding, but the adjustment steps of the seat pocket direction are also extremely simple. Even if you hold the child in one hand, you can easily operate it with the other hand, which is convenient for parents to use and adjust outdoors.

[0016] 2. The seat pocket in this baby stroller can not only rotate, but also can be adjusted and folded by sliding forward and backward. When sliding forward and backward, by pulling the seat pocket adjustment handle, the fixation between the seat pocket chassis group can be quickly unlocked, and then the seat pocket group can be pushed. At this time, the seat pocket adjustment handle can be loosened, and then when the seat pocket group is adjusted to the next group of translation slots, the translation pin will automatically pop out to fix the position of the seat pocket. The front and rear position of the seat pocket can be adjusted simply and quickly. By using this adjustment function in conjunction with the seat pocket rotation function, a larger adjustment space can be given to the footrest group, which can make the child's legs more comfortable; this function can also be used in conjunction with the backrest adjustment function, so that the child can get a more comfortable posture when lying down, which is also beneficial to the balance of the baby stroller.

[0017] 3. When the stroller is not in use or needs to be carried, it can be folded. When folding the stroller, the upper push handle group and the lower push handle group with longer lengths are folded, thereby avoiding the problem that the upper push handle group and the lower push handle group are too long and inconvenient to carry. At the same time, the front foot group, the rear foot group and the push handle group of the frame can be rotated and overlapped, and stacked into a rectangular block, thereby avoiding the waste of volume occupied by the frame being too large and the internal hollowness. At the same time, the backrest can be folded down to contact the seat pocket, saving the volume of the seat pocket group, and can also cooperate with the forward and backward sliding function of the seat pocket group, so that the volume of the folded stroller is compressed to the maximum and the exterior is roughly rectangular, and there will be no overly protruding parts that affect carrying and storage.
