806 other end is engaged with the 7th rotation seat 803, when the 3rd bindiny mechanism is in the second state, 806 pairs the 7th rotations of torsion spring
Seat 803 applies rotating torque, so, after the 3rd bindiny mechanism is switched to the second state by first state, torsion spring 806 pairs the 7th
Rotation seat 803 applies rotating torque, so that guard block 5 is turned down automatically from the rear direction of trend perambulator body, this
Sample avoids the need for going manually to overturn guard block so that the folding of perambulator is more convenient.
The method for folding of above-mentioned perambulator comprises the steps：
Pressing piece is pressed, the first bindiny mechanism is switched to the second state by first state so that upper boom and lower beam can phases
To upset, then upper boom is overturn to the front portion of baby's vehicle main body so that upper boom and lower beam close up；
During upper boom overturns, the second rotation seat pulls up drag-line, when upper boom is turned near the position of lower beam, drag-line
Fixture block 604 is pulled out from two draw-in grooves 607, so that the second bindiny mechanism switches to the second state by first state, is made
Obtain lower beam, foreleg and back leg relative to overturn；
Continue to close up upper boom to the anterior upset of baby's vehicle main body up to upper boom and lower beam, then by lower beam to baby's vehicle main body
Rear portion upset so that lower beam is gradually drawn close to back leg, when lower beam overturn, lower beam drives handle to rotate, drive when handle is rotated
6th rotation seat, 802 synchronous axial system, by the second fluted disc 804 near the side of the 7th rotation seat 803 when the 6th rotation seat 802 is rotated
To promotion；
After lower beam flips an angle, the 3rd bindiny mechanism is switched to the second state by first state by handle so that the 7th
Rotation seat 803 unlocks mutually locking state with fixed seat 801, then due to the active force of torsion spring 806 so that the 7th rotation seat
803 overturn to the rear portion of baby's vehicle main body, so as to drive guard block 5 to overturn to the rear portion of baby's vehicle main body；
Then lower beam and foreleg are overturn to relative direction, so that lower beam, back leg and foreleg close up；
Complete the folding of perambulator.
Below only just present invention application preferably example is made that explanation, but is not to be construed as the limit to claim
System, the structure of the present invention can have other changes, be not limited to said structure.In a word, all independent claims in the present invention
