Description

Technical Field

[0001] The utility model relates to the field of child strollers, in particular to a quick folding structure of a child stroller. Background Art

[0002] A stroller is an important tool for carrying children for long and short distance travel and outings. The existing strollers have reached a certain level of design in terms of appearance, comfort, etc., but the folding structure design of the frame is not very ideal. The most common situation is that the storage volume after folding is not high compared with the unfolded volume before folding, and the space occupied is still large, making it difficult to carry when traveling and outings. The existing folding strollers for children are more troublesome to fold. The armrests, backrests and seats connected to the legs need to be unlocked before they can be folded one by one. In this process, both hands are required to operate at the same time. If the operator holds the child in one hand, the folding structure of this stroller is convenient to operate and is more troublesome. Utility Model Content
