Sliding folding and unfolding mechanism of baby carriage

Abstract

The invention relates to the technical field of products for babies and discloses a sliding folding and unfolding mechanism of a baby carriage. The sliding folding and unfolding mechanism comprises a handrail mechanism, a folding and unfolding mechanism and a seat mechanism, wherein the seat mechanism is connected with the handrail mechanism through a connecting piece, the seat mechanism is used for providing a baby seat, the lower end of the folding and unfolding mechanism is provided with a wheel group, the folding and unfolding mechanism is connected on the low ends of the two sides of the handrail mechanism through fixed joints, the folding and unfolding mechanism is connected above the fixed joints on the two sides of the handrail mechanism through sliding joints in a sliding way, elastic clamping and fastening mechanisms are respectively and internally arranged on the two sides of the handrail mechanism, and the elastic clamping and fastening mechanisms are used for fastening the sliding joints when the baby carriage is folded or unfolded. The sliding folding and unfolding mechanism of the baby carriage is simple and firm in structure, reduces the weight of the carriage and is simple and convenient to operate, the sliding joints can be enabled to keep in a relatively steady state when the baby carriage is folded or unfolded, and the sliding folding and unfolding mechanism of the baby carriage provides convenience for a user to use the baby carriage and is high in safety performance.

Description

technical field [0001] The invention relates to the technical field of infant products, in particular to a sliding and retracting mechanism of a stroller. Background technique [0002] Baby stroller is a tool cart designed for the convenience of baby's outdoor activities. It is the baby's favorite means of transportation for walking, and it is also a must for mothers to take their babies to the street for shopping. With the development of science and technology and the improvement of people's living standards, there are higher requirements on the operability and structural safety of baby strollers. [0003] At present, the general stroller is to set a foldable structure on each joint of the frame to realize its foldable performance, so that the stroller has a retractable function. Forming the inter-hinged structure of the three plays a better effect for the folding of the baby carriage. However, this kind of folding mechanism of the existing baby carriage is actually r...

[0003] At present, the general stroller is to set a foldable structure on each joint of the frame to realize its foldable performance, so that the stroller has a retractable function. Forming the inter-hinged structure of the three plays a better effect for the folding of the baby carriage. However, this kind of folding mechanism of the existing baby carriage is actually realized through more linkage structures, and the structure is complicated, which increases the The weight of the car body is also not convenient for the baby carriage to move after it is folded, which causes a lot of inconvenience to the user. Moreover, the existing baby carriage is easy to be folded by the baby carriage when people use it or when the baby is playing. The joint is pinched, and the safety performance is not high
