Frame is connected by the first sliding sleeve, and the rear wheel support is located in the first sliding sleeve and can slided in the first sliding sleeve, the push rod
It is slidably arranged on front-wheel support, the push rod is rotated with rear wheel support and is connected, when vehicle frame is in deployed condition, front-wheel branch
Frame mutually supports vertical with rear wheel support, and the push rod stretches towards the direction away from front-wheel；When vehicle frame is in folded state, the front-wheel
Support is mutually drawn close with rear wheel support, and the push rod shrinks towards the direction close to front-wheel.
It is preferred that, the upper end of the front-wheel pole, which is fixed, is equiped with the second sliding sleeve, and the push rod is slidably located in the
In two sliding sleeves.
Specifically, the junction of the push rod and rear wheel support is less than the position where the second sliding sleeve.
Specifically, when locking device unblock, the push rod can be slided along the bearing of trend of front-wheel pole.
Specifically, the front-wheel support, rear wheel support, push rod and the first sliding sleeve formation slider-crank mechanism, when locking dress
Unblock is put, the push rod, which is slided, drives rear wheel support movement, is slided when the push rod towards the direction close to front-wheel, the trailing wheel branch
The upper end of frame is drawn close towards front-wheel direction；Slided when the push rod towards the direction away from front-wheel, the upper end of the rear wheel support is drawn
Rise towards away from the movement of front-wheel direction.
It is preferred that, the connecting rod intersects vertically with front-wheel pole, and first sliding sleeve is rotatably arranged on connecting rod away from front-wheel
The end of pole.
It is preferred that, the bottom of the push rod and the upper end of rear wheel support are connected by pin rotation.
It is referred to above to the inferior noun of locality upper all around, be the orientation when the children trolley normal is used
Make what is defined.
The scope of the present invention, however it is not limited to the technical scheme of the particular combination of above-mentioned technical characteristic, while should also contain
Lid other technical schemes as formed by being combined above-mentioned technical characteristic or its equivalent feature.Such as features described above and sheet
Disclosed in application（But it is not limited to）Technical characteristic with similar functions carries out technical scheme etc. formed by replacement mutually.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：Vehicle frame only has front-wheel
The a limited number of part such as support, rear wheel support, push rod, first sliding sleeve, the part of whole children trolley is less, and vehicle frame is succinct,
It is with low cost；Front-wheel support, rear wheel support, push rod, the first sliding sleeve composition toggle, push-and-pull push rod can be achieved with entirely
The folded/expanded of children trolley, step is few, and operation is simple；Front-wheel support, rear wheel support and push rod are drawn close one after folding
Rise, take small volume, it is easy to carry and transport.

Embodiment
As shown in Figures 1 to 6, a kind of children trolley of the present invention, including with deployed condition and folded state
Vehicle frame, the front-wheel 7 for being arranged on vehicle frame lower front portion, the trailing wheel 8 for being arranged on vehicle frame lower rear and for vehicle frame to be locked in into exhibition
Drive/the locking device of folded state.The vehicle frame includes front-wheel support 1, rear wheel support 2 and push rod 3.The front-wheel 7 is arranged on
The bottom of front-wheel support 1, the trailing wheel 8 is arranged on the bottom of rear wheel support 2.
Front-wheel pole 5 and be fixedly installed on the top of front-wheel pole 5 that the front-wheel support 1 is connected including bottom with front-wheel 7
Connecting rod 6, the connecting rod 6 intersects vertically with front-wheel pole 5.In the present embodiment, connecting rod 6 is weldingly fixed on front-wheel pole 5.Institute
State connecting rod 6 to be connected by the first sliding sleeve 4 with rear wheel support 2, first sliding sleeve 4 is rotatably arranged on connecting rod 6 away from front-wheel pole 5
End.The rear wheel support 2 is located in the first sliding sleeve 4 and can slided in the first sliding sleeve 4.The push rod 3 is slidably set
Put on front-wheel support 1, the bottom of the push rod 3 is connected with the upper end of rear wheel support 2 by pin rotation.The front-wheel
The upper end of pole 5 is fixed and is equiped with the second sliding sleeve 9, and the push rod 3 is slidably located in the second sliding sleeve 9.The push rod 3 with
The junction of rear wheel support 2 is less than the position where the second sliding sleeve 9.The front-wheel support 1, rear wheel support 2, push rod 3 and first
The formation slider-crank mechanism of sliding sleeve 4.
When vehicle frame is in deployed condition, front-wheel support 1 and the mutually support of rear wheel support 2 are vertical, and the push rod 3 is towards away from front-wheel
Stretch in 7 direction；When vehicle frame is in folded state, the front-wheel support 1 mutually draws close with rear wheel support 2, the push rod 3 towards by
Nearby the direction of wheel 7 is shunk.
When locking device unblock, the push rod 3 can be slided along the bearing of trend of front-wheel pole 5.The slip band of push rod 3
Dynamic rear wheel support 2 is moved, and is slided when the push rod 3 towards the direction close to front-wheel 7, and the upper end of the rear wheel support 2 is towards the side of front-wheel 7
To drawing close；Slided when the push rod 3 towards the direction away from front-wheel 7, the upper end of the rear wheel support 2 is pulled up towards away from front-wheel 7
Move in direction.
When the children trolley of deployed condition is folded, locking device is unlocked first, then by push rod 3 to the direction of front-wheel 7
Promote, the slide downward in the second sliding sleeve 9 of push rod 3, the front-wheel support 1, rear wheel support 2, the sliding sleeve 4 of push rod 3 and first are formed
