Description

A kind of seesaw

Technical field

The utility model relates to a kind of amusement appliance, is specifically related to a kind of seesaw.

Background technology

Seesaw mainly is made up of flat board, support, rotating shaft three parts, player's branch is sitting in dull and stereotyped two, and the upwards active force that relies on both sides to produce in turn swings up and down dull and stereotyped two with pedaling in turn, because its simple and easy and elegant sense of soaring in short-term is subjected to liking of child deeply.

Obviously, two of seesaw will keep certain balance, just can pay the price for it, when the body weight for humans that is sitting in dull and stereotyped two ends differs big, the application of force imbalance on both sides, heavy one side is just gruelling, needs to pedal soil fertility and just can make the other side's bottom with very big, and also be less than peak and just fallen, be difficult to the swing that utilizes inertia continuous; And then it is more impossible that a people wants to play seesaw, and one side of sitting the people is always much bigger than empty one side power; Therefore the structure of seesaw of the prior art is quite high to the requirement of balance.

Summary of the invention

The utility model purpose provides does not a kind ofly have the balance requirement to dull and stereotyped two, even can the single laborsaving seesaw of playing of a people.

For achieving the above object, the technical solution adopted in the utility model is: a kind of seesaw, mainly form by flat board, support, rotating shaft, flat board is set up on the support by rotating shaft, dull and stereotyped two ends are provided with handrail, described dull and stereotyped below has at least an end to be provided with spring, and described spring is fixedlyed connected with dull and stereotyped bottom.

In the technique scheme, an end of described dull and stereotyped below is provided with a spring, fixedlys connected with dull and stereotyped in the top of described spring, and the bottom is provided with a spring pedestal, and spring is fixedlyed connected with ground by the spring pedestal.When having only a player, the spring force of a dull and stereotyped end can be seen another player as, and its principle is: when the player is sitting in an end of no spring, applied gravity at this end of flat board, the spring terminal perk, the player is pedaled ground, and flat board upwarps, and spring terminal bounces back under the effect of restoring force, when being up to the standard line, because dull and stereotyped movement velocity is bigger, can break through equalization point, to the lower compression spring; When the player fell, the spring of compression had an elastic force that makes progress, and the player is pedaled pin rapidly when landing, by the elastic force that makes progress of spring, the flat board that the player is held upwarps once more, and can reach than for the first time higher height, so repeatedly, reach the purpose of single object for appreciation seesaw.

Another kind of technical scheme is, the two ends of described dull and stereotyped below are respectively equipped with a spring, fixedlys connected with planar bottom surface in the top of each spring, and the bottom is provided with a spring pedestal, and spring passes through the spring pedestal fixedlys connected with ground.Added spring at dull and stereotyped two ends, the both sides that make recreation also can be easily when body weight differs big, play smoothly, because spring is an one-period property oscillating element, power-assisted can when moving, seesaw be provided, therefore, body weight if can the controlled motion frequency than double recipe, can be by the elastic force and the restoring force of the upper and lower cooperation of two ends spring, offset the influence of self unnecessary gravity easily.

In the technique scheme, fixedly connected by removable structure between described spring and flat board; Perhaps, fixedly connected by removable structure between described spring and spring pedestal; Can the both be removable connection also.Thereby, when the one-man plays, the spring pedestal of an end can be pulled down together with spring, perhaps, when two people's body weight gap was big, the spring of people's one end that can body weight is heavier was dismantled.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model at least one end below flat board is provided with spring, when at one end spring being set, single player is played, having broken seesaw must two rule that the people plays.

2. equally for above-mentioned reasons, when the two ends of flat board all are provided with spring, can make under the unbalanced situation of dull and stereotyped two ends body weight, easily finish recreation as usual, need not the balance requirement.
