The specific embodiment
Below in conjunction with embodiment specific embodiment of the utility model is described.
Embodiment 1:
As shown in Figure 1, according to the children trolley that the utility model is implemented, its vehicle frame comprises:
A pair of handspike 1, the upper end of handspike 1 is connected by a cross bar, makes whole handle be reverse U shape;
U font foot-operated 4, this foot-operated 4 is made of across the treadle 3 between connecting rod 2 bottoms the connecting rod 2 of a pair of longitudinal extension and one;
Across the seat bar 5 between handspike 1 bottom, rotating around the first turning cylinder a between the both ends of this bar 5 and the handspike 1 is connected, and the upper end of riding 4 connecting rod 2 also rotates around the first turning cylinder a with the bottom of handspike 1 respectively and is connected;
Upper end and handspike 1 foot lever 6 behind the bonded assembly that rotates, its pivot center is level;
Across the rear transverse rod 9 between the bottom of back foot lever 6, and be rotating the connection between the both ends of rear transverse rod 9 and the back foot lever 6, pivot center is level;
Along the bottom bar 10 that fore-and-aft direction extends, the rearward end of this bottom bar 10 rotates with the middle part of rear transverse rod 9 and is connected, and pivot center is level;
The last strut 8 that the middle part of upper end and seat bar 5 is fixedly connected, its bottom rotates with the approximate mid-section of bottom bar 10 and is connected, and pivot center is level;
The a pair of front-wheel of the leading section both sides of present bar 5 is installed, and the pair of rear wheels that is installed in foot lever 6 bottoms, back;
Be installed in the car load lockout mechanism between handspike 1 and the connecting rod 2.
Said structure makes this children trolley to fold in the mode shown in accompanying drawing 4,5, and after folding, will ride 4 towards the below bending, and the volume after having reduced greatly to fold is convenient to take in.
When deployed condition, the structure of this children trolley as shown in Figure 1.To ride 4 stretchingly, then connecting rod 2 and handspike 1 conllinear form the state shown in accompanying drawing 1,2; To ride 4 towards the below bending, then form state as shown in Figure 3.According to the height difference that is sitting in the children in the car, can regulate foot-operated 4 bending angle, change the high and low position of treadle 3, make children sit more comfortablely.
In said structure, rear transverse rod 9 and bottom bar 10 constitute the bottom bracing frame.Except the structure described in the present embodiment, the bottom bracing frame can also be linked together as long as can and go up strut 8 with back foot lever 6 by multiple constituted mode.Front-wheel 71 also can be designed to pair of right and left, or only single-wheel is installed at the middle part, forms three wheel barrows.
