| titleOfInvention | Pumping mechanism using lever |
| abstract | The present invention relates to a pumping mechanism using a lever for allowing a child or a student to directly perform a buoyancy change experiment according to a weight change of a heavy weight, that is, to visually check the water level and the amount of water discharged according to the weight of the heavy weight. It relates to a pumping mechanism using a lever. In addition, the present invention relates to a pumping mechanism using a lever, which enables the user to experience the principle of the lever by allowing a heavy object to be placed on a lifting plate using the lever. The pumping mechanism using the lever according to the present invention is the water inlet and drainage port is formed on the side wall and the liquid tank is stored; An elevating plate installed in the tank so as to be elevated; A heavy material placed on an upper portion of the elevating plate; It characterized in that it comprises a; lever to raise or lower the weight on the lifting plate. |
