Embodiment Construction
[0042] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. The folding mechanism 50 of the present invention is suitable for the stroller frame 1 to prevent the hand-clamping problem of the stroller frame 1 during unfolding.
[0043] Such as figure 1 As shown, the stroller frame 1 of the present invention includes a rider 10, a front leg 20, a connecting rod 30 and a rear leg 40, and a retracting mechanism is passed between the lower end of the rider 10, the upper end of the front leg 20, and the upper end of the connecting rod 30 50 are pivotally connected to each other, and the front foot 20 and the rider 10 extend slightly backward. The front end of the rear foot 40 is connected to the lower end of the front foot 20 and extends slightly downwards. In addition, a retractable operation part 11 is provided on the upper end of the driver 10 , and the retractable mechanism 50 can b...

The invention discloses a folding mechanism. The folding mechanism is used for hinging the lower end of a stroller handle, the upper end of a front leg and the upper end of a connecting rod of a stroller frame, the lower end of the stroller handle and the upper end of the front leg are mutually separated to form a safety area, and the safety area is used for preventing the stroller frame from being sheared and extruded in the unfolding process. Therefore, when the folded stroller frame is unfolded, the safety problems of shearing and extruding are solved, and the risk of clamping hands in the operation process is avoided. The folding mechanism has the advantages that the safety is higher in the folding and unfolding processes of the stroller frame, the structure is simple, and the folding and the unfolding are easy and convenient. The invention also discloses the stroller frame using the folding mechanism.
Description
technical field [0001] The invention relates to the field of children's products, in particular to a stroller frame and a retractable mechanism that can prevent hands from being pinched during retraction. Background technique [0002] In the design of the frame structure of the cart, in order to meet the practicality and portability required by consumers, the frame of the cart is generally designed to be foldable, so that it can be opened when in use It is for the baby to sit on, and when not in use, it can be folded into a smaller volume for easy storage or portability. [0003] In order to realize the folding of the cart frame, a folding mechanism is provided on the frame to connect the cart frame and realize the folding of the cart frame, but the existing folding mechanism, some The structure is too complicated, and some folding operations are not easy enough, and there is a safety problem of shearing and extrusion in the process of opening the cart frame after it is fol...
