Preferably, the third articulated section 831, the 4th articulated section 32, two second gears 93, two second adapters 62 pass through
The pivot joint of one second pivot 94.
When sliding the pulling handle rod 4 down, except the above-mentioned first driving inclined-plane 71 driving 5 release the lock rear foot of rear foot release the lock part lock
Determine except mechanism, the second driving inclined-plane 72 can interact with the second inclined-plane 60, and the second actuator 61 is pushed toward far from front foot
The direction of pipe 1 is mobile, and tetrad moving part 613 is all pushed into the second accommodating hole, on the 6th inclined-plane 621 and the 5th inclined-plane
Under 611 interaction, two second adapter 62 is moved in the opposite direction by promotion, to respectively drive two second
Gear is mobile toward opposite direction, so that two second gears are detached from ipsilateral third tooth socket and only engage with the 4th ipsilateral tooth socket.
At this point, armchair connecting seat 31 can be rotated relative to fixed seat 8, i.e., seat 3 can be rotated relative to front foot pipe 1, seat locking release the lock.
And because tetrad moving part 613 is all pushed into the second accommodating hole, so that the second actuator 61 will not interfere with the rotation of seat 3
It folds.
(not shown) in other embodiments is also possible to be provided with left and right two thirds pivot joint on the downside of the armchair connecting seat
Portion 831, the front fixed part 83 are provided with the 4th articulated section 32, and the third articulated section 831, far from one end of front foot pipe 1
For the structure of four articulated sections 32 as above-described embodiment describes, the second adapter 62 is same, but under this configuration, institute
The segment design that the second actuator 61 can as above be divided into third STATEMENT OF FEDERALLY SPONSORED and tetrad moving part is stated, is also possible to monoblock type, i.e.,
Without separating into third STATEMENT OF FEDERALLY SPONSORED and tetrad moving part.Second actuator 61 is also possible to include the third STATEMENT OF FEDERALLY SPONSORED being fixedly connected
612 and tetrad moving part 613, but it is this identical as monoblock type the second actuator structural nature.
In the present embodiment, 8 front side of fixing seat, in other embodiments, the seat are articulated on the downside of the seat 3
Chair 3 can also be articulated in other appropriate orientations of front foot pipe 1.
The seat locking may be set to be other known feasible structures, as long as deenergizing by seat release the lock part 6
It pushes and release the lock.
In the present embodiment, the 7 lower end two sides of main actuator are respectively arranged with the first driving inclined-plane 71 and the second driving
Inclined-plane 72, in other embodiments, the main actuator 7 can be set to two and be individually fixed in 4 lower end two sides of pulling handle rod
First driving inclined-plane 71 and the second driving inclined-plane 72 is respectively set on two components in two components.
In conjunction with shown in Fig. 1,3,8, it is provided between the pulling handle rod 4 and front foot pipe 1 for limiting the opposite sliding of the two
Handle rod lock mechanism 40, in the present embodiment, the handle rod lock mechanism 40 include mounting base 41, button 42, third bullet
Spring 43, locking pin 44, the mounting base 41 is fixedly connected on 1 upside of front foot pipe, and the mounting base 41 is provided with installation
Slot 411, the button 42 are connected to mounting groove 411, and 42 middle part of button is pivotally connected with 411 side wall of mounting groove, to be formed as lifting up
It is board-like, and the third spring 43 is set between 411 bottom wall of 42 side of button and mounting groove, 44 one end of locking pin and button 42
Other side connection；Corresponding perforation, the pulling handle rod 4 or main are provided on 411 bottom wall of mounting groove and 1 tube wall of front foot pipe
The side of actuator 7 towards the perforation is provided with one or more lock holes；Under the action of third spring 43, the locking
44 other end of pin is inserted into a lock hole after sequentially passing through the perforation on 1 tube wall of 411 bottom wall of mounting groove and front foot pipe, from
And handle rod lock mechanism is in the lock state, pulling handle rod 4 cannot slide down with respect to front foot pipe 1, thus after cannot going release the lock
Foot locking mechanism and seat locking, cart of the present invention are locked to unfolded state.
When to fold cart of the present invention, push button 42 passes through seesaw principle, institute towards the side of third spring 43
It states locking pin 44 to move outward, so that the other end of locking pin 44 is exited out of pulling handle rod 4 lock hole, at this point, handle lever lock
Determine mechanism release the lock, pulling handle rod 4 can slide up and down in front foot pipe 1, so that rear foot locking mechanism described in release the lock and seat be gone to lock
Mechanism folds children trolley of the present invention.
Preferably, be provided on the pulling handle rod 4 between the upper and lower every two lock holes, when children trolley of the present invention is using
Under state, in the lock hole of the insertion of locking pin 44 lower section；When move down pulling handle rod 4 and also drive rear foot release the lock part 5 with
After 6 release the lock rear foot locking mechanism of seat release the lock part and seat locking, under the restoring force effect of third spring 43, locking
In the lock hole of the insertion of pin 44 top, to directly up mention institute again after release the lock foot locking mechanism and seat locking
State pulling handle rod 4, more convenient operation.
In other embodiments, more lock holes can be set on the pulling handle rod 4, to realize the height of pulling handle rod 4
Degree adjustment, thus to adapt to the cart person of different heights.
In other embodiments, the handle rod lock mechanism is also possible to other known feasible structures, pushes away described in release the lock
The locking releasing mechanism of barre 4 is also possible to other known feasible structures, and it is not technical key point of the present invention, thus do not do into
One step repeats.
The present invention folds children trolley easy to operate and further includes the front-wheel 20 of downside before being set to the front foot pipe 1, sets
It is placed in the rear-wheel 30 of 2 back lower place of the rear foot.
