The top of after-poppet 12 and the lower part of lower push-rod 131 rotate connection, in the present embodiment, the top of fore-stock 11, after-poppet 12
Top and lower push-rod 131 lower part three component same axis rotation connection；The lower part phase on the top of strut 15 and upper push-rod 132
Rotation connection, the lower part of strut 15 rotates with after-poppet 12 to be connect；First sliding part 16 can extend along the length of strut 15
Direction is slidably arranged on strut 15；Armrest assembly 14 rotates and connect with the first sliding part 16 and lower push-rod 131 respectively；The
The one end of one connecting rod 17 and the one end of second connecting rod 18 rotate connection, the other end of first connecting rod 17 and fore-stock 11
Rotate connection, and second connecting rod 18 rotates with after-poppet 12 and connect, and the second sliding part 19 can be along the length of second connecting rod 18
Extending direction is slidably arranged on second connecting rod 18, and the lower end of strut 15 also rotates with the second sliding part 19 and connect.
In the present embodiment, the first sliding part 16 uses the first sliding sleeve, and the first sliding sleeve is set on strut 15, and can be along support
The length extending direction of bar 15 is slidably arranged.First connecting rod 17 is arranged in second sliding part 19 and the rotation of second connecting rod 18 connects
Between the rotation connection for connecing place and second connecting rod 18 and after-poppet 12, the second sliding part 19 uses the second sliding sleeve, and second is sliding
It is set on second connecting rod 18, and can slidably be arranged along the length extending direction of second connecting rod 18.
Armrest assembly 14 includes the first handrail 141 and the second handrail 142, is provided in the first handrail 141 and the
The one end of the slot that two handrails 142 match, the second handrail 142 is fixed in the slot, the first handrail 141
One end rotate and connect with the first sliding part 16, the first handrail 141, which also rotates with lower push-rod 131, to be connect.
It is preferred that the first handrail 141 is mutually detachably connected with slot, it, can in this way before the children's ride-on children trolley
First handrail 141 is separated with 142 phase of the second handrail, again by the first handrail after being rested on children trolley to children
141 and second handrail 142 be fixed together so that it is convenient to the children's ride-on children trolley.
First handrail 141 includes the first segment 141a extended along the longitudinal direction and the second segment vertically extended

Ground is arranged on first segment 141a, and first segment 141a rotates with the first sliding part 16 and connect, second segment 141b and lower push-rod 131
Rotate connection.The structure of first handrail 141 is set in this way, after armrest assembly 14 can be enable to fold more with push-rod assembly 13
Step up thickly to be close together.
In the present embodiment, locking mechanism, which is arranged at the rotation connection of 132 two components of lower push-rod 131 and upper push-rod, to be used for
The position of both parts is locked, when locking mechanism is in the lock state, since the connection of each rod piece of stroller frame 1 is closed
System, entire stroller frame 1 are just in the lock state.The specific structure of locking mechanism is not that the claimed technology of this patent is wanted
Structure in the prior art can be used in point.
The children trolley further includes the seat mechanism 4 being arranged in stroller frame 1.
When the children trolley is in unfolded state, locking mechanism is in the lock state, as depicted in figs. 1 and 2.
When children trolley needs to fold, locking mechanism first is unlocked, forward and is pressed downward upper push-rod 132, makes upper push-rod
132 forward overturning drawn close with lower push-rod 131, and downwardly turn over lower push-rod 131 and upper push-rod 132, so that the first cunning
Moving part 16 so that the overturning of armrest assembly 14 is drawn close with 131 phase of lower push-rod, and makes along the length extending direction slide downward of strut 15
Strut 15 is also downwardly turned over and is drawn close with after-poppet 12, when strut 15 persistently downwardly turns over, connect the second sliding part 19 along second
The length extending direction forward slip of bar 18, and rotate second connecting rod 18 relative to after-poppet 12, it is pulled by first connecting rod 17
Fore-stock 11 is turned over to be drawn close with after-poppet 12, and folding process is as shown in Figure 3 and Figure 4, until each bar of composition stroller frame 1
Part close proximity is together, final to fold as shown in Figure 5 and Figure 6.In the children trolley folding process, armrest assembly 14 is only with
One sliding part 16 is flipped when sliding, and will not be stretched forward or backward along its own length extending direction, thus in handrail
When 14 folding of component, enough spaces are reserved without being thought of as 14 folding of armrest assembly, this pushes away folded double children
Bassinet structure is more compact, small in size, easy to carry and storage.
