Do not answered between person yet it is conllinear or it is parallel to ensure stroller frame fold when both sides back stay can be rotatably to interphase
To drawing close.
In the present embodiment, locking mechanism is set between slide bushing assembly 6 and front support rod 11 to lock the two.
Shown in Figure 1 when stroller frame is unfolded, left push rod 21 is in unfolded state with right push rod 22 in push rod 2,
Locking mechanism locks, and slide bushing assembly 6 is fixed with respect to fore-stock 1, structure between lower-left push rod 211, upper left strut 41 and front support rod 11
At triangular structure, also triangle structure between bottom right push rod 221, upper right strut 42 and front support rod 11;Front support rod 11, a left side
Triangle structure between back stay 31, lower-left strut 51, also structure between front support rod 11, right rear strut 32, bottom right strut 52
At triangular structure, stroller frame is in stable unfolded state.
It is shown in Figure 3 when needing to fold up stroller frame, push rod 2 is folded first, i.e., is pushed away upper left
Bar 212 is overturn separately down with upper right push rod 222, so that left push rod 21 is separately folded with right push rod 22.It then will locking
Mechanism unlocks so that slide bushing assembly 6 slidably, then pushes the top of lower push-rod on front support rod 6 so that push rod 2 acts on two
The upper strut 4 of side, as shown in figure 4, upper strut 4 is rotated relative to push rod 2, the lower part of upper strut 4 drives slide bushing assembly 6 along front support rod
11 slide downwards;Slide bushing assembly 6 drives the back stay of both sides along 11 slide downward of front support rod again(Left back strut 31 and right rear strut
32)Top respectively along 11 forward downward of front support rod to moving, this drives the lower supporting rod 5 of both sides with respect to front support rod 11 and two simultaneously
The back stay of side is rotated and is gradually drawn close to front support rod 11, finally, left push rod 21, right push rod 22, upper left strut 41, upper right strut
42, lower-left strut 51, bottom right strut 52, left back strut 31 are mutually drawn close with front support rod 11 respectively with right rear strut 32, are formed such as
Structure shown in Fig. 5, the stroller frame after the folding is compact-sized, and occupied space is smaller, easily stored and carrying.
When needing stroller frame to be unfolded in use, then first push rod 2 can be unfolded, pulling push rod 2, can make then up
Push rod 2 acts on strut 5 and the length direction upward sliding that drives slide bushing assembly 6 along front support rod 11 so that rear branch
Frame 3 is rotated relative to front support rod 11 with lower supporting rod 5 and is gradually spread out respectively.After stroller frame is fully deployed, locking mechanism locking,
The stroller frame can steadily be in unfolded state as shown in Figure 1.
In conclusion the child umbrella handle vehicle of the present invention, the rod piece quantity of stroller frame is few, simple for structure, and when expansion makes
Type is beautiful, only needs to can be realized by lifting or pushing push rod 2 in the expansion of stroller frame and folding operation, and operation is very square
Just, and stroller frame each rod piece can be closely close together after folding, the structure after folding closely, occupied space
It is smaller, convenient for storage and carry.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
