Referring to fig. 1-3, a weight balance mechanism of a seesaw comprises a base 1, the base 1 is made of magnetic material, and magnetic poles are respectively located at two ends, a central shaft 3 is fixedly connected to the middle of the upper end of the base 1, plate bodies 2 are movably mounted at two sides of the upper end of the base 1, the plate bodies 2 are located at the outer side of the central shaft 3, liquid storage cavities 4 are formed in the middle of the two ends of the plate bodies 2, press blocks 5 are movably mounted at two ends of the plate bodies 2, and the press blocks 5 are located above the liquid storage cavities 4, so that the press blocks 5 can move downwards when the upper ends of the press blocks are under pressure, the lower ends of the press blocks 5 are movably connected with the bottom surfaces of the liquid storage cavities 4 through springs 6, so that the press blocks 5 can move upwards under the action of the springs 6 after the upper ends of the press blocks 5 lose pressure, thereby automatically resetting is realized, the repeated work capability of the weight balance mechanism is ensured, and an adjusting cavity 11 is formed in the middle of the plate body 2, the adjusting cavity 11 is positioned on the outer side of the middle shaft 3, the lower end of the inner cavity of the plate body 2 is provided with a communicating groove 13, the communicating groove 13 communicates the liquid storage cavity 4 with the adjusting cavity 11, and the liquid storage cavity 4 and the speed reducing block 12 are filled with filling liquid, so that when the pressing block 5 moves downwards, pressure can be applied to the filling liquid in the liquid storage cavity 4, the filling liquid can move into the adjusting cavity 11 through the communicating groove 13, the middle parts of the two ends of the plate body 2 are fixedly connected with fixed blocks 7, the middle parts of the two ends of the plate body 2 are fixedly connected with coils 8, and the coils 8 are positioned on the outer side of the fixed blocks 7, so that after the fixed blocks 7 are electrified, the coils 8 can generate magnetism and are matched with the base 1 made of magnetic materials, the two ends of the plate body 2 generate downward magnetic attraction force, the lower end of the inner cavity of the plate body 2 is provided with a movable groove 9, the movable groove 9 is positioned above the communicating groove 13, and the lower half part of the movable groove 9, which penetrates through the lower end of the coil 8, make the conducting material at coil 8 middle part expose, the inboard activity of activity groove 9 has cup jointed regulation pole 10, and it makes for copper material to adjust pole 10, make when adjusting pole 10 and moving to the outside under receiving the pressure, can contact through adjusting pole 10 and coil 8, make the number of turns of coil 8 change, thereby along with the increase of briquetting 5 bearing pressure, the magnetic field intensity of fixed block 7 reduces, make can cooperate through human weight and the decurrent magnetic attraction of fixed block 7, reach both ends balance, make seesaw ability normal use, 7 outside coils 8's of both ends fixed block winding direction is the same, make when gravity balance mechanism normally works, both ends fixed block 7 homoenergetic receives the magnetic attraction that comes from base 1 the same strength, thereby guarantee gravity balance mechanism's balanced efficiency.

Referring to fig. 1-3, a deceleration block 12 is movably sleeved at the middle of a plate body 2, the deceleration block 12 is located at the outer side of a center shaft 3, and the deceleration block 12 contacts the center shaft 3, when the seesaw is not used, the deceleration block 12 contacts the center shaft 3 in a normal state, so that resistance is large, the outer end of the deceleration block 12 contacts the inner side of an adjusting rod 10, so that when a gravity balance mechanism stops working, negative pressure suction is generated in a liquid storage cavity 4 under the action of a spring 6, the adjusting rod 10 moves inwards under the cooperation of filling liquid, so that the deceleration block 12 is pushed to move inwards, further friction between the deceleration block 12 and the center shaft 3 is enhanced, and the rotation efficiency of the seesaw is rapidly reduced by matching with the magnetic attraction force rapidly increased at the lower end, and further, the higher end has sufficient time to get down.

Referring to fig. 1-3, wherein the deceleration block 12 is a weight block, when one end of the seesaw swings to a lower position, the deceleration block 12 moves outwards under the action of gravity, so that the deceleration block 12 pushes the liquid filled in the adjustment cavity 11, the adjustment rod 10 moves outwards, and further the magnetic attraction force downward at the lower side is reduced, so that the overall weight at the lower side is smaller than the overall gravity at the higher side, and further the seesaw can automatically swing in the opposite direction, and the seesaw can continuously swing along with the reciprocation of the deceleration blocks 12 at the two ends, the inner side of the adjustment rod 10 is relatively thin, so that when the inner side of the adjustment rod 10 contacts the deceleration block 12, the situation that the filled liquid cannot push the adjustment rod 10 to move outwards due to too tight contact between the adjustment rod 10 and the deceleration block 12 does not occur, and a triangular bump is arranged below the end of the deceleration block 12 located in the adjustment cavity 11, and the bevel edge is not contacted with the inner wall of the adjusting cavity 11, so that when the pressure of the filling liquid in the adjusting cavity 11 is increased, the speed reducing block 12 can move outwards for a certain distance through the triangular convex block, the speed reducing block 12 is separated from the middle shaft 3, and the seesaw can normally swing when the automatic swing mechanism normally works.

The using method of the invention is as follows:

and (3) balancing the weight: when people sit at the two ends of the seesaw to play an entertainment, under the action of the weight of the people, the pressing block 5 overcomes the elastic force of the spring 6 to move downwards, so that liquid in the liquid storage cavity 4 flows into the adjusting cavity 11 along the communicating groove 13 under the action of the pressure, the adjusting rod 10 is pushed to move towards the left under the action of the pressure of the liquid, the adjusting rod 10 is in contact with the coil 8 with proper turns, under the action of the adjusting rod 10 made of copper materials, the turns of the coil 8 can change along with the weight of the people, the magnetic force generated by the fixing block 7 under the action of the coil 8 is adjusted, the magnetic attraction between the fixing block and the base 1 is reduced along with the increase of the weight of the people, and the weights at the two ends of the seesaw can be adjusted in a self-adaptive mode;

slowly swinging the lower part of the user: when a person suddenly drops from one end of the seesaw, the pressing block 5 is quickly reset under the action of the elastic force of the spring 6, filling liquid is quickly moved into the liquid storage cavity 4 under the action of negative pressure suction force generated in the liquid storage cavity 4, the adjusting rod 10 is driven to move inwards, the adjusting rod 10 pushes the speed reducing block 12, the pressure between the speed reducing block 12 and the middle shaft 3 is increased, the friction force between the speed reducing block and the middle shaft is increased, and the rotation speed of the seesaw is quickly reduced under the action of the increase of the magnetic suction force on the lower side of the seesaw, so that a person at the higher end can have enough time to get off;

automatic swinging: through setting up the speed reduction piece 12 that possesses a dead weight, make at seesaw normal use, and one end rotates when lower position, its inboard speed reduction piece 12 slides to the outside under the effect of gravity, thereby produce pressure to adjusting 11 intussuseptions in chamber, make the filling liquid promote to adjust pole 10 and move to the outside, thereby make 8 turns of coil in the gravity balance mechanism further less, and then reduce the magnetic attraction between lower one side base 1 and the fixed block 7, make lower one end less for perk one end weight, thereby make perk one end can automatic fall, and under the effect of both ends speed reduction piece 12 reciprocating motion, thereby make the seesaw ability automatic swing.
