Pushchair in the market generally can only fold front and back when folding, thereby after folding, cause volume still very big, not easy to store, carry and transport, and the Push rod hand cart after folding is exposing outside, be easy to cause damage in depositing, carry and transporting, also have the baby of working as to be positioned over for a long time in the perambulator, perambulator is because the distortion of lower support, be easy to cause sinking, cause baby's discomfort.

Summary of the invention:

In order to solve the problems of the technologies described above, the invention provides a kind of Foldable baby stroller of depositing, carry and transporting of being easy to.

The technical solution adopted for the present invention to solve the technical problems is: a kind of Foldable baby stroller, comprise and taking the shape of the letter U, have backward the end plastic support of forming by arm at the bottom of end plastic and two and by preceding plastic and two front frames that preceding arm is formed, on plastic of the described end and the end arm wheel is housed, the top of arm links to each other by the bottom of upper joint with a push rod before described, the bottom of described push rod is fixed on the preceding arm by hypozygal, be provided with bracing frame between described hypozygal and the end arm, described two push rod tops are connected with one and have the collapsible handgrip that folds button, be provided with the collapsible bottom supporting rod of an arc between the arm of the described end, be provided with two strut bars between described collapsible bottom supporting rod and the end plastic.

Further: support frame as described above is the X-shaped bracing frame.

Solve the baby when just being placed on perambulator, keep the stability under loading of perambulator, further: support frame as described above is upright support structure bracing frame.

Further: described push rod and preceding arm lap are provided with a L shaped cover sheet, described L shaped cover sheet inside is provided with the groove that an opening makes progress, described slot opening place is connected with the bottom of push rod, described push rod is provided with lock slider in the bottom, described lock slider can be embedded in groove, described lock slider top is by set pin) be fixed with a spring, the lock slider top also is connected with traction lock simultaneously, described traction lock top is connected on the slide block, and described slide block is positioned at the poke hole at push rod rear portion.

The present invention can not only before and after folding can also about folding, be more convenient for depositing, carry and transport, and the handgrip after folding do not expose outside vehicle body, prolonged the life-span of car, and the effect of passing through bracing frame, collapsible bottom supporting rod and lower supporter, solved the problem that car sinks.
