[0018] Each weight plate 25 is provided with a transversely distributed through hole 251. Correspondingly, the weight plate shaft 26 is provided with a plurality of limit holes 261 arranged in sequence from top to bottom. The number of the limit holes 261 is equal to the number of the weight plates 25. Each limit hole 261 is concentrically arranged with the through hole 251 in the corresponding weight plate 25.

[0019] The adjustment chair further includes a latch 28 . A vertical slot 241 is formed on one side of the weight box 24 . The latch 28 passes through the vertical slot 241 transversely and is inserted into a through hole 251 on one of the weight plates 25 and a corresponding limiting hole 261 .

[0020] A shock absorbing spring 13 is fixed below both ends of the swing rod 1. The two shock absorbing springs 13 are respectively sleeved on the outside of the lower ends of the weight plate shafts 26 in the two adjustable seats.

[0021] Two upper footrests 2 are fixed above the swing rod 1 . The two upper footrests 2 are respectively arranged on the inner sides of the seats 18 in the two adjustable chairs and are respectively located on both sides of the support seat 10 .

[0022] Two lower footrests 3 are fixed below the swing rod 1 . The two lower footrests 3 are respectively arranged on the inner sides of the seats 18 in the two adjustable chairs and are respectively located on both sides of the support seat 10 .

[0023] A rotating disk 8 is also fixed to the upper end of the worm 9 .

[0024] A protective cover 11 is further provided outside the swivel seat 14 and the support seat 10 , and the protective cover 11 is fixed on the top of the support 15 .

[0025] Directions:

[0026] If two people with a large difference in weight sit at the two ends of the pendulum rod 1 respectively, they can hold the turntable 8 with their hands and turn it to drive the worm 9 to rotate, and then drive the transmission shaft 16 to rotate with the help of the worm wheel 7, so as to drive the rack 5 to move left or right with the help of the gear 6, and then drive the pendulum rod support 12 to move left or right in the guide seat 4, thereby adjusting the distance between the two ends of the pendulum rod 1 and the support seat 10 and making the distance between the two unequal. In this way, the distance between the fulcrum and the two ends of the lever can be adjusted according to the lever principle to adapt to two people with a large difference in weight. Even two people with a large difference in weight can play smoothly and happily; the mutual engagement of the worm 9 and the worm wheel 7 also realizes automatic locking, and the position of the pendulum rod 1 will not change even if the turntable 8 is released.

[0027] It is worth mentioning that if the user is a single person and sits on one of the seats 18, as long as the fulcrum position is adjusted to a suitable position, according to the principle of moment balance, even a single person can use the seesaw of the present invention, which breaks the limitation that the seesaw must be used by two people.

[0028] Moreover, the present invention has the function of fitness equipment when used by one person or two people. During operation, the user steps on the upper footrest 2 or the lower footrest 3 with both feet, and then pushes hard with both feet to straighten the legs, and the seat 18 will move outward with the help of the slide rail 17 to drive the baffle 23 to move outward. In this process, since the user moves outward with the seat 18, the torque on the side where the user is located is increased, thereby changing the torque difference on both sides of the seesaw; and the baffle 23 will pull the wire rope 27 to move when moving, and then with the help of the first pulley 20, the second pulley 21 and The third pulley 22 drives the weight plate shaft 26 to move upward, thereby pulling one of the weight plates 25 and all the weight plates 25 above the weight plate 25 upward in the counterweight box 24 with the help of the weight plate shaft 26; finally, the user puts force on his feet and bends his legs, and each weight plate 25 that moves upward will move downward by its own weight, and then pull the seat 18 inward by means of the wire rope 27 and the weight plate shaft 26 to reset, thereby reducing the torque on the user's side to change the torque difference on both sides of the seesaw again, thereby forming a cycle.

[0029] Before performing the above operation, the number of weight plates 25 can be determined according to the user's age and leg strength by selecting the tolerable stepping weight, and then the latch 28 is first pulled out, and then the latch 28 is passed through the vertical slot 241 and inserted into the through hole 251 on the selected weight plate 25 and a corresponding limit hole 261; thereafter, the weight plate 25 with the latch 28 inserted and each weight plate 25 located above the weight plate 25 will adapt to the user's leg strength with the help of the weight plate shaft 26 and the wire rope 27.

[0030] The present invention also adds a way to play the seesaw, that is, after two people adjust the support points to achieve a preliminary balance at both ends, one person randomly exerts force to pedal the pedals to adjust the position of the seat, while the other person tries to maintain balance and also exerts force to adjust the position of his or her own seat accordingly, and counts the time of maintaining balance; then the roles are exchanged, and the time of maintaining balance is counted again to determine the winner of the game. The party who passively adjusts the seat position, the longer the balance is maintained, is considered the winner, which increases the fun.

[0031] The present invention can adjust the fulcrum position by adjusting the relative position of the rocker arm 1 and the support seat 10, and can also adjust the torque size by adjusting the positions of the two seats 18. Even when the weight difference between the two persons is large or there is only one person, it can be used smoothly and continuously, which completely breaks through the limitations of the use conditions of the seesaw, so that the user can always get a better use experience; in addition, the present invention can be used as fitness equipment under the conditions of one or two persons, which increases the function of the seesaw and can also play a role when it is idle, thereby improving the practicality.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
