The present embodiment working principle:
When needing to fold, by being unlocked by pressing button, push card lock collar is detached from first inner chamber, makes the first connector and second
Connector can relatively rotate, and rotating disk, which rotates with the first connector and passes through the first drawstring, pulls the first STATEMENT OF FEDERALLY SPONSORED, the first linkage
Part by the relative motion of the first skewed slot and the first spacer pin, make the first spacer pin the first latch piece of drive far from the first card hole with
Unlock linkage fold mechanism slides sliding sleeve along upper pipe support and drives to drive support by first connecting rod and second connecting rod respectively
Frame and front wheel carrier are folded against, while sliding sleeve slides the top splenium in the second STATEMENT OF FEDERALLY SPONSORED of press along upper pipe support, makes the second linkage
Part is mobile with the glide direction of sliding shell, and the second STATEMENT OF FEDERALLY SPONSORED is by the second skewed slot and the second spacer pin relative motion, drive the
Two latch pieces are far from the 4th card hole and the 5th card hole, to unlock the upper pipe support and cradle of opposite expansion, and because the second drawstring
For lead with the first drawstring on the contrary, when the first drawstring draws the first STATEMENT OF FEDERALLY SPONSORED, the second drawstring acts on cant turntable
Tractive force disappears, and clamping pin is connected in the second card hole under the second elastic top-pressure part effect, and user shrinks down tube by external force
Frame enters in upper pipe support, and cradle makes clamping pin be moved to down tube by the mating reaction of the guiding chamfering of guiding surface and clamping pin
It is provided on the side of third card hole, and is connected in third card hole with the movement of cradle, lock when realizing that rear wheel frame is shunk
Next wheel carrier.Pram folding is realized through the above steps.
When needing to be unfolded, user pulls arm-rest frame to drive the first connector and the second connector relative motion to shape is unfolded
State, detent disk move it recovery to the first connector of clamping lock and the second connector by the press effect of the 4th elastic top-pressure part
Position, keep the first connector and the second connector relatively fixed, at the same the second connector drive support frame, linkage folding device
Restore with front wheel carrier to unfolded state, and rotating disk makes the first drawstring act on leading for the first STATEMENT OF FEDERALLY SPONSORED with the rotation of the first connector
Gravitation disappears, and sliding sleeve in clamping lock to the first card hole, is locked at rear-wheel under the action of the first elasticity press by the first latch piece
