Description

Technical Field

[0001] The invention relates to the technical field of children's strollers, and in particular to a safety bicycle quick-release rotating and folding mechanism. Background Art

[0002] Children's bicycles are a major category of children's vehicles, which include four categories: children's bicycles, children's strollers, baby walkers and children's tricycles.

[0003] Existing children's strollers usually have an integrated frame. On the one hand, the shape of the entire vehicle cannot be changed again after the product is assembled. In order to maintain the stability of the stroller, the stroller is generally large in size, and the required storage space is correspondingly large. In addition, the use venue of the children's stroller is mostly outdoor open space, that is, the storage location of the stroller is usually not together with the use venue, and it needs to be moved to reach it. In this case, it is very inconvenient to move the relatively large stroller. On the other hand, due to the large size of the entire stroller after assembly, it is basically impossible to package the product after installation into a complete vehicle. It can only be packaged in parts and stacked. Consumers need to assemble it by themselves after purchase, which causes many inconveniences to consumers. For this reason, we propose a safe folding mechanism for a stroller. For this reason, we propose a safe bicycle quick-release rotating folding mechanism. Summary of the invention
