Plastic seesaw

First, the product principle introduction

The principle of plastic seesaw is the principle of leverage, the pressure of people on children's seesaw is power and resistance, and the distance from the fixed point of people to children's seesaw is the power arm and the resistance arm, respectively. Due to the downward speed up and down, the downward speed of the high is greater than that of the low, and the high decreases, while the low is warped under the action of the principle of leverage, and so on.

We all know that playing children's seesaw is a play child play equipment that needs to be cooperated to play up, and when playing, it requires good cooperation between two children, so this kind of children's play equipment is not suitable for children under 5 years old to play if there is no adult company, because children do not know how to take care of each other's feelings, do not want to play on their own, do not care what situation the other party is in, often prone to accidents.

Second, product safety precautions

1. Plastic seesaw can only sit one child at a end, if the weight difference between two children is too large, you can discuss with the child, change a child of similar weight to play together, instead of sitting on the light side of another child.

2. Two children should sit face to face on the children's seesaw, do not turn around, and sit back to back.

3. Let your child hold the handle tightly with both hands and do not try to touch the ground or empty it with both hands. Feet should be placed on a special pedal. If there is no pedal, it can hang down naturally instead of curling up under the children's seesaw, otherwise the child's feet may be pressed down when the children's seesaw is pressed down.

4. If other children are playing with children's seesaws, keep their distance while waiting next to them, and never put your feet under the upturned children's seesaw, do not stand in the middle of the beam of the children's seesaw, or try to climb to the up and down children's seesaw.
