Description
[technical field]
The invention patent relates to a kind of perambulator skeletons convenient for folding.
[background technique]
Trolley is very common child utensil, children are put walking is onboard push by adult not only can be big generous
Become the nurse action of people, moreover it is possible to keep children itself more comfortable, while also safer.However, current trolley is universal
Structure is more complicated, and mostly not foldable, and some can be folded also can only be partially folded, not only folding process is number
It is tired, it needs a part a part successively to fold, many users is caused all cannot expertly to complete folding process in this way, and opening up
It is also required to a part a part when opening operation to be successively unfolded, so causes trouble to the use of many users.In addition, after folding
Volume is bigger, bad carrying.In this way, when car do not need in use, when needing to carry, car place need to occupy compared with
More spaces thus can carry out big inconvenience to storage or conveyer belt.
Currently, perambulator has become child's article indispensable in developmental process, perambulator in the market generally can be into
Row folds or expansion, but existing perambulator is sufficiently complex convenient for the perambulator skeleton structure of folding, causes perambulator heavy, after folding
Volume is still larger, and manufacturing cost is high, and due to the complexity of structure, people are very laborious when folding, and are easily damaged perambulator.
Pram folding among existing design is ineffective, and folding and expansion are inconvenient.
Perambulator inconvenience among existing design is converted between children's seating and standing posture and lying position two states, gives people
Bring inconvenience during using perambulator.
Perambulator among existing design is not provided with erect position, cannot stand after perambulator folding, it has not been convenient to put.
Since there are the above problems, it is necessary to propose that solution, the present invention are exactly made in this context to it
's.
[summary of the invention]
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing a kind of convenient for folding
