Specific embodiment
Come with specific embodiment below in conjunction with the accompanying drawings technical scheme is further elaborated.
Definition below in relation to direction is all to install this children trolley when using, and child rests on and seen on children trolley
Come to define, the left and right directions shown in fore-and-aft direction that is, Fig. 2, Fig. 4, wherein left are front in the direction observing, after right is,
Above-below direction in above-below direction that is, each accompanying drawing.
Referring to the children trolley shown in Fig. 1～4, including having the stroller frame of deployed condition and folded state, located at pushing away
The anterior front-wheel 10 in vehicle carriage bottom, the trailing wheel 20 located at stroller frame bottom rear portion, it is used for stroller frame in stroller frame
It is locked in the locking mechanism (not shown) of deployed condition.This stroller frame includes push rod 1, fore-stock 2, after-poppet 3, seat bar
4th, fork 5 and rear pole 6.
The bottom of push rod 1 is rotated with the top of fore-stock 2 and is connected, the top of after-poppet 3 be rotationally connected to push rod 1 with
On at least one of fore-stock 2 part, in the present embodiment, the bottom of push rod 1, the top of fore-stock 2 and after-poppet 3
Top is pivotally connected together.Front-wheel 10 is arranged on the bottom of fore-stock 2, and trailing wheel 20 is installed on the bottom of after-poppet 3.
The front portion of seat bar 4 is rotationally connected on fore-stock 2 by first axle 7, and first axle 7 is located at front on fore-stock 2
Support 2 and push rod 1, the lower section of after-poppet 3 transit point.One end of fork 5 is passed through the second axle 8 and is rotationally connected on present bar 4, pendulum
The other end of bar 5 is rotationally connected on after-poppet 3.Under stroller frame deployed condition, fork 5 is located at the lower section of seat bar 4, so
A bar 4 support along the vertical direction can be provided to a certain extent.
Between seat bar 4 and push rod 1, the top of rear pole 6 is rotationally connected on push rod 1 rear pole 6, rear pole 6
Lower rotational ground connect on present bar 4 or fork 5, the bottom of rear pole 6 is passed through the 3rd axle 9 and is rotationally connected bar of being present herein
On 4 rear portion.Wherein, the second axle 8 is located between first axle 7 and the 3rd axle 9 along the bearing of trend of seat bar 4.
Between after-poppet 3 and fork 5, both are locked by setting locking mechanism, or set between after-poppet 3 and seat bar 4
Put locking mechanism to lock both, stroller frame can be made to be in stable deployed condition when launching.Certainly, locking mechanism
