Tray balance for physics teaching experiments

The utility model discloses a pallet balance for physics teaching experiments, comprising a metal crossbeam and a fixed pedestal, the metal crossbeam is fixedly installed at the middle position of theupper end of the fixed pedestal, and pallet iron frames are arranged at two sides of the upper end of the fixed pedestal. The tray balance for the physics teaching experiment has good adjusting and limiting fixing effects through the novel adjusting supporting leg structure, firstly, the threaded round rod in the middle of the upper end is welded through the metal iron block, so that the tray balance is fixedly connected in a welding mode, is firmer in use and is not prone to falling off, and the practicability is high; limiting and fixing effects can be well achieved through limiting screwson the periphery of the outer end of the threaded round rod, a person finds out a corresponding proper height by rotating the limiting screws on the distance of the threaded round rod during adjustment and fixes and locks the
