Baby carriage frame and its folding mechanism

Abstract

The invention discloses a retracting mechanism, which is arranged on a bottom frame of a baby carriage frame and is used for assisting the baby carriage frame to retract. The bottom frame is provided with a bottom pipe; the retracting mechanism comprises a clamping part and a retracting operation part, wherein when the baby carriage frame is in use, the carriage frame has a backward-pushing trend to the clamping part due to self gravity, so that the clamping part clamps tightly without being pivoted, and the baby carriage frame is in lock; when the carriage frame needs to be retracted, the retracting operation part is stepped by the foot and then moves, so that the retracting operation part drives the clamping part to move and enables the clamping part to pivot for unlocking; due to the backward-pushing trend of the carriage frame to the clamping part, an operator can easily push an upper frame downwards so as to realize retraction of the baby carriage in the three-dimensional space; and not only is the retracting operation of the baby carriage frame smoother, but also the baby carriage frame with the retracting mechanism can achieve smaller retracting size after retraction. In addition, the invention also discloses the baby carriage frame with the retracting mechanism.

Description

technical field [0001] The invention relates to a retractable mechanism and a baby carriage with the retractable mechanism, in particular to a baby carriage with smoother folding operation and smaller folded volume. Background technique [0002] Baby carriages are more and more widely used in families with babies. At present, in order to better meet people's needs for the portability and storage of baby carriages, most of the baby carriage frames are designed as foldable structures. In this way, baby carriages It is in an open state when in use, and when not in use, the stroller frame can be folded so that the stroller can be folded into a smaller volume for convenient storage or carrying. Of course, the stroller not only needs to be folded, but people also have higher and higher requirements for the simplicity of its folded operation. At the same time, it is also hoped that the folded stroller will have a smaller volume for storage or carrying, so some foldable mechanisms a...

Problems solved by technology

Of course, the stroller not only needs to be folded, but people also have higher and higher requirements for the simplicity of its folded operation. At the same time, it is also hoped that the folded stroller will have a smaller volume for storage or carrying, so some foldable mechanisms are used On the baby carriage frame, to realize the convenience of the folding operation of the carriage frame, and further reduce the volume of the folded baby carriage, but the design of the existing baby carriage frame and the design of the folding mechanism on it make the baby carriage There is still room for improvement in the collapsing operation of the shelf
