As bottom right tube socket 121 is rotated along the first preset direction a together, under the elastic reaction of third elastic component, so that rotational pin 122
One end far from third elastic component can be connected to the bottom wall of driving groove 134 always, and in rotational pin 122 along the first preset direction a
During rotation, rotational pin 122 can be moved to the first end of driving groove 134 from the second end of driving groove 134, work as rotational pin
122 when being moved to the first end of driving groove 134, and connection ring 133, connecting tube 131 and the first transmission gear 132 can be by rotational pins
122 drive along the first preset direction a rotation, to drive 140 band of the second transmission component using the first transmission gear 132 of rotation
Dynamic seat-assembly rotation；When bottom right tube socket 121 is rotated along the second preset direction b, rotational pin 122 can be from driving groove 134
First end is moved to second end, and rotational pin 122 can be transmitted the bottom wall of slot 134 and push away towards one end close to bottom right tube socket 121
It squeezes, during rotational pin 122 is moved to second end from the first end of driving groove 134, ring 133, connecting tube will not be drivingly connected
131 and first transmission gear 132 rotate.
It should be noted that connection ring 133 can open up multiple driving grooves 134, and multiple driving grooves 134 are along connection ring 133
Circumferential setting, when bottom right tube socket 121 is rotated along the second preset direction b, rotational pin 122 can be from the of driving groove 134
Two ends slide into another adjacent driving groove 134, when bottom right tube socket 121 is rotated along the first preset direction a again, rotation
Pin 122, which can be plugged in the driving groove 134, drives 130 further occurrence of the first transmission component to rotate, i.e. the every edge of bottom right tube socket 121
First preset direction a rotation can once drive seat-assembly rotate predetermined angle, such as: 10 °, 30 °, 60 ° etc., if desired after
Continuous swiveling seat component then needs to rotate bottom right header assemblies 120 to the second preset direction b, switches to rotational pin 122 along the
In another driving groove 134 of two upstreams preset direction b, a bottom right tube socket 121 then is rotated to the first preset direction a again
Driving seat-assembly rotates predetermined angle again, and can be with above steps may be repeated multiple times until seat-assembly turns to accordingly
Position；It should be further noted that 6 driving grooves 134 are provided in connection ring 133 in the present embodiment, in other implementations

In conclusion the beneficial effect of rotary seat structure and children trolley of the invention is:
The rotary seat structure of the embodiment of the present invention can be rotated to be made with right large joint rotation connection ground bottom right header assemblies
The rotation of first transmission component, the first transmission component of rotation are able to drive the second transmission with first transmission component transmission connection
Component rotation, and drive the horizontal direction of seat-assembly to rotate using the second transmission component, it so, can be right by rotation
Down tube holder assembly realizes seat-assembly rotation in the horizontal direction, does not need in the horizontal direction integrally to turn the rotary seat structure
It is dynamic, seat-assembly can be made to be rotated in the horizontal direction, so that when the rotary seat structure rotates in the horizontal direction not
Vulnerable to the influence of outer space environment, the rotation of seat-assembly also can relatively be neatly realized in more narrow space, improve
The convenience that uses.
Children trolley provided in an embodiment of the present invention can use right push handle component and left push handle component be same when in use
When driving bottom right header assemblies and lower-left header assemblies rotation, to drive the rotation of the first transmission component, and utilize rotationally the
One transmission component drives the rotation of the second transmission component, so that the second transmission component driving seat-assembly rotates in the horizontal direction, this
Sample one does not need the entirety of rotation children trolley when needing swiveling seat component angle in the horizontal direction, but can be with
Individually control seat-assembly rotates in the horizontal direction, when rotation influenced by space environment it is smaller, even if more narrow
Space also more can neatly rotate, and improve the convenience used.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
