Buoyancy survey device for physics experiments

The utility model discloses a buoyancy survey device for physics experiments belongs to physical experiment technical field, the device including the container that is used for adorning liquid, with the spring dynamometer of body coupling awaits measuring, the key is: the device still including the montant that has the base, fix at the horizon bar of montant upper end, erect the reel on the horizon bar, connecting wire on the reel constructs with lift hoisting machine that spring dynamometer's upper end fixed connection formed to the body that awaits measuring after fixing the fixed pulley on the horizon bar. In the measurement process, need not be more portable the spring dynamometer of student only needs to rotate the reel and puts suitable length with the connecting wire, then with the reel fix can, treat spring dynamometer reading again after static, measure and accomplish the back, with the connecting wire time twine on the reel can, improved measured data's accuracy, simple structure, convenient operati
