Description

Technical Field

[0001] The utility model relates to the technical field of baby strollers, in particular to a novel foldable baby stroller frame. Background Art

[0002] A baby stroller is a "means of transportation" for babies. It requires someone to help push or pull the stroller. It is generally composed of a sunshade, a seat cushion, a sleeping basket and an anti-smog cover. The service life is generally three to five years. The age of the baby should be taken into consideration when purchasing. Nowadays, the functions of baby strollers have been upgraded to allow sleeping, eating, playing, etc.

[0003] For example, the authorization announcement number "CN207416931U" is a foldable baby stroller frame. The entire baby stroller frame can be folded quickly, and the folded volume is smaller, which can be stored in a smaller space, meeting people's requirements for small-volume foldable baby strollers. However, the height of the push rod of the foldable baby stroller frame cannot be adjusted. When the user is tall, the user needs to bend over to use it. Long-term use can easily cause the user to be overworked. At the same time, when the folded baby stroller frame needs to be moved, the folded baby stroller frame is not fixed and is easy to fall apart, making it inconvenient for the operator to move. Utility Model Content

[0028] Working principle:

[0029] When using the new folding stroller frame:

[0030] Preparation process:

[0031] When the user uses it, first pull the push rod 9 upwards according to the operator's height to drive the two sliding rods 301 to move. The movement of the sliding rod 301 drives the first clamping block 303 and the vertical block 304 to slide along the sliding groove processed on the support rod 2. When the vertical rod 301 moves to the appropriate position, the operator turns the two second bolts 302 to make the ends of the second bolts 302 press against the outer wall of the sliding rod 301 to achieve the height adjustment of the push rod 9. When a taller user pushes the push rod 9, there is no need to bend over, and long-term use will not cause excessive fatigue to the taller user.

[0032] When the foldable baby stroller frame is folded:

[0033] First, rotate the second bolt 302 to retract the sliding rod 301 into the support rod 2, then rotate the second bolt 302 again to make the end of the second bolt 302 press against the outer wall of the sliding rod 301, and prevent the sliding rod 301 from sliding out of the support rod 2, then rotate the first bolt 11 connecting the front bracket 1 and the support rod 2, then rotate the support rod 2 counterclockwise to make the outer wall of the support rod 2 fit against the outer wall of the front bracket 1, then tighten the first bolt 11 connecting the front bracket 1 and the support rod 2, and finally rotate the first bolt 11 connecting the rear bracket 6 and the protrusion 7 to make the front bracket 1 rotate counterclockwise. When the outer walls are in contact with each other, the first bolt 11 connecting the rear bracket 6 and the protrusion 7 is tightened, and then the handle 502 is rotated forward to drive the worm 503 to rotate, which drives the worm wheel 504 to rotate. The rotation of the worm wheel 504 drives the transmission rod 505 to rotate, thereby driving the pull rope 507 to move downward. The user wraps the pull rope 507 around the outer wall of the fixing rod 10 on the rear bracket 6, and finally sticks the Velcro 509. After the user folds the baby stroller frame, the pull rope 507 can fix the support rod 2 and the rear bracket 6, and the front bracket 1, the support rod 2 and the rear bracket 6 will not be scattered, which is convenient for the user to move the baby stroller frame after folding.

[0034] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
