Moving part, the sliding part is slidably on another part, and the relatively described fore-stock of the sliding part or the push rod turn
Set dynamicly.
Further, the sliding part is to be opened on the sliding pin on a described part, another described part
Provided with chute, the sliding pin is slidably plugged in the chute.
Further, the sliding pin is regularly on the push rod, and the chute is opened in the upper of the fore-stock
Portion, the sliding pin can be plugged in slidably and rotationally in the chute around Pivot Point Center line.
Preferably, there is the connecting rod extended downwardly, the bottom of the connecting rod and the top of the fore-stock on the push rod
Between relative can slide with being rotationally connected.
Further, a pocket care frame, the upper end of the connecting rod and the seat pocket care frame phase are fixedly provided with the push rod
It is fixedly connected.
Further, the fore-stock include from front to back gradually the branch bar portion of updip, from the upper end of the branch bar portion to
The montant portion of upper extension, the montant portion is connected with the push rod.
Further, when the stroller frame is in deployed condition, the connecting rod and the montant portion are along same length
Spend direction extension.
Preferably, the locking mechanism, which is located between the push rod and the fore-stock, is used to lock both.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：The children of the present invention
Stroller, its rod member quantity is few, and structure is very simple, and stroller frame has good stability upon deployment.Carried out by stroller
Upset push rod before and after only being needed when folding with expansion, operation very facilitates, and the cart structure after folding is also very compact, space-consuming
It is smaller, with good comprehensive performance.

Embodiment
Technical scheme is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
Referring to the children trolley shown in Fig. 1 to Fig. 6, including stroller frame with deployed condition and folded state, it is located at
The wheel assembly of stroller frame bottom, and for the locking mechanism by stroller frame locking in the deployed state.
The stroller frame includes fore-stock 1, after-poppet 2 and push rod 3, and fore-stock 1 intersects and in infall with after-poppet 2
Phase pivot is connected, and the bottom of push rod 3 is connected with the top phase pivot of after-poppet 2, can phase between the top of fore-stock 1 and push rod 3
To sliding and rotatably connecting.
It can specifically be connected in the following way between fore-stock 1 and push rod 3：The top of fore-stock 1 and push rod 3 the two
In part, sliding part is provided with one of part, the sliding part is slidably on another part, and the sliding part phase
Push rod 3 or fore-stock 1 are rotationally set.
In the present embodiment, fore-stock 1 includes from front to back the gradually branch bar portion 11 of updip, upward from the upper end of branch bar portion 11
The montant portion 12 of extension, after-poppet 2 from back to front gradually updip and intersected with branch bar portion 11 and by the phase pivot of first axle 8 connect
Connect.There is the connecting rod 4 extended downwardly on push rod 3, be connected by the connecting rod 4 with the montant portion 12 on the top of fore-stock 1.At this
In, the chute 6 extended along its length is offered in montant portion 12, the lower end of connecting rod 4 is rotatably provided with sliding pin 5, the sliding pin 5
Slidably it is plugged in chute 6, so just realizing relative can slide between push rod 3 and the top of fore-stock 1 and relative can turn
Dynamic connection.Certainly, sliding pin 5 also can regularly be located at the lower end of connecting rod 4, now so that sliding pin 5 can be around itself in chute 6
Axial line is rotationally set.
