Set up and have on the side of the 3rd hole clipping, and be connected in the 3rd hole clipping with the movement of cradle, to realize lock when rear wheel frame shrinks
Tight rear wheel frame.Pram folding is realized by above-mentioned steps.
When needing to launch, user pulls arm-rest frame to drive the first connector and the second connector relative motion to launching shape
State, screens dish moves it recovery to kayser the first connector and the second connector by the top pressure effect of the 4th elastic top casting die
Position, make the first connector and the second connector be relatively fixed, simultaneously second connector drive bracing frame, linkage fold device
Recover to deployed condition with front wheel carrier, and rotating disk rotates with the first connector and makes the first stay cord act on leading of the first STATEMENT OF FEDERALLY SPONSORED
Gravitation disappears, and the first latch piece blocks under the effect of the first elastic top pressure and is locked in the first hole clipping, and slip cap is locked at trailing wheel
On frame, to support front wheel carrier and bracing frame by first connecting rod and second connecting rod in the deployed state, simultaneously as the second stay cord
Contrary with the lead of the first stay cord, when the pull strength that the first stay cord draws the first STATEMENT OF FEDERALLY SPONSORED disappears, the second stay cord pulls
Cant turntable rotation, cant rotating disk is matched with cant boss by inclined thrust surface, makes cant driven by rotary disc card pin away from second
Hole clipping and the 3rd hole clipping, with unlock shrink rear wheel frame, the rear wheel frame of unblock make under the effect of air spring cradle from manage
Automatic-expanding in frame, the second latch piece is locked in the 4th hole clipping and the 5th hole clipping by the effect card of the 3rd elastic top casting die, with
Rear wheel frame after locking expansion.Launch perambulator by above-mentioned steps and perambulator is maintained at deployed condition.
It is described above as combining one or more embodiments that particular content provides, does not assert that the application's is concrete real
