In the present invention, when user uses the device, whole equipment and the center of gravity of children are determined when use first Position, after children are sitting in seat 7, since the both sides of chuck 17 are 10 structure of the first universal joint that can be freely rotated, The position of 17 relative equilibrium bar 13 of constantly regulate chuck so that children are sitting in balancing pole 13 when on cushion 9 and are in vertically not The state of shaking rotates adjustment axis 3, the rotation of 3 opposite thread axis 4 of adjustment axis so that the opening of chuck 17 becomes smaller, chuck 17 and balance Bar 13 is clamped, for relatively dutiful children, when double swerve by a small margin, since position of centre of gravity is in chuck 17 Place so that when seat 7 deviates to the left, counterweight 1 can deviate to the right accordingly, balancing pole 13 itself can be relatively fixed axis 5 and telescopic shaft 11 rotate, since fixed position is in position of centre of gravity, there are one physics centers of gravity for each object, as long as having found Its equalization point, so that it may to go to manipulate it with minimum strength；

Children can shake seat 7 during movable so that seat 7 is swung, and ground is placed in since chair frame 2 is fixed on On, it plays one and slows down and eliminate this active force for shaking and bringing, seat 7 is kept to be in the core of equilibrium state always Position is exactly the first universal joint 10, it can be with the weight of support whole equipment, while the low friction resistance function of offer can effectively subtract It is influenced less with isolation applied external force, seat 7 is made to remain the state of balance and stability；

But once when the scope of activities of children is excessive so that change the angle position of entire chair frame 2, not by The resultant force of the chair frame 2 of any power is zero, is standing balance, it is assumed that children have given the power of seat 7 one to the left, and seat 7 is always It accelerates to the left, at this moment, it is static unbalance, in order to allow it to come back to the state of standing balance, is needed again to seat 7 one sizes of chair are identical, the opposite power in direction, but the two power not only need equal in magnitude, and direction is on the contrary, they are also needed to On the same line, an object will keep balancing, and it is zero not only to need resultant force, it is also desirable to resultant moment zero, due to balancing pole 13 both ends are separately connected seat 7 and counterweight 1, and seat 7 moves to the left, and corresponding counterweight 1 moves to the right, wherein seat 7, Balancing pole 13 and the position of centre of gravity of counterweight 1 are fixed axis 5 and are fixed at one, to seat 7 when the rotation of balancing pole 13 and match 1 running torque direction is weighed on the contrary, size is the same, is zero with joint efforts, resultant moment is also zero, so whole equipment remains able to keep Balance, and the angle of seat 7 is level angle；

If but the range that deviates of seat 7 it is larger when, the left side that the center of gravity chair frame 2 of whole equipment is contacted with ground It a little rotates, gravity will generate a clockwise torque at the point of rotation, this torque can make us with the point of rotation Centered on rotate clockwise, allow on the right side of chair and come back on ground, ground can surround the point of rotation to our support force and produce A raw torque counterclockwise, the clockwise moment generated with gravity balance each other, and power and torque are all balances, if but weight The heart is displaced to the surface of the point of rotation, and suffered is effectively on same straight line, so torque disappears, this shape State is difficult to maintain, and when center is continued to when moving to left the left side for changing to the point of rotation, the torque generated at the point of rotation is via suitable Hour hands become in order to counterclockwise, and clockwise torque balances, and will topple over, since seat 7 is in balancing pole 13 and counterweight 1 Under effect, horizontal angle position is remained, to the meeting vertical drop of seat 7, rather than rollover is toppled over, and in cushion 9 Under buffer protection, children can be sitting on the ground rather than rollover topples over head towards ground, are effectively protected the safety of children.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
