The mutually locking of component 4.The children trolley also includes setting present conversion locking mechanism between bar assembly 5 and second connecting rod 7
（It is not shown）.The conversion locking mechanism is used to lock the seat bar assembly 5 and second connecting rod 7.When the vehicle frame is in positive exhibition
Between open position and reverse expanded position during switching position, the locking joint 100 is unlocked, and the conversion locking mechanism is kept
The seat bar assembly 5 and second connecting rod 7 are locked to each other in lock-out state.So, only push-rod assembly 3 can rotate, seat
Bar assembly 5, first connecting rod 6 and the remains stationary of second connecting rod 7 do not link with the push-rod assembly 3.
When the vehicle frame folding, the locking joint 100 and the conversion locking mechanism are unlocked.And seat pillar 51
Also mutually unlocked between back support bar 52.Drive the push-rod assembly 3 and fluffy bar assembly 4 around first axle 101 turn over
The after-poppet 2 is drawn close.The fore-stock 1 rotates backward around first axle 101 and drawn close with the after-poppet 2.The seat pillar 51
Overturn around the 3rd axle 103, the back support bar 52 is turned over around the 7th axle 107, and the first connecting rod 6 moves upwards, final car
Each rod member of frame mutually draws close folding and completes to fold.
It can be seen that in children trolley described in the utility model, by the setting of first connecting rod 6 and second connecting rod 7, make vehicle frame
Each rod member can link together.By turn down push-rod assembly 3 and fluffy bar assembly 4 can a step realize the folding of whole children trolley
Folded, folding step is few, simple and convenient.Each rod member is limited by the annexation with other rod members in whole vehicle frame simultaneously, is folded
Drawn close afterwards between each rod member closely, the space between each rod member greatly reduces, the vehicle frame small volume after folding.The utility model institute
The children trolley stated can also realize the commutation of vehicle frame by the rotation of push-rod assembly 3, and in commutation process, other rod members can be protected
Hold motionless, only push-rod assembly 3 is rotated, and the stability of seat bar assembly 5 is kept in handoff procedure, ensures the security of children's ride-on.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit in technological thought of the present utility model
It is interior to carry out different change and implementation.
