The invention discloses a balance for physics teaching, which comprises a bottom plate, a support column, an external thread, a rotating plate, an internal thread, a base, a fixed rod, a fan-shaped scale, a pointer, a fixed shaft, a beam, a threaded rod, an adjusting nut, a hanging ring, Lanyards, trays, fixing plates, elastic springs, rubber blocks, reservoir housings and glass strips. This kind of balance for physics teaching has a reasonable structure and novel design. Through the mutual cooperation of the set support column, rotating plate, base, bottom plate, water storage shell and glass strips, the horizontal placement of the bottom plate is realized, which is convenient for the stable use of the balance. , to ensure the accuracy of balance measurement, easy to use, through the interaction between the set rubber block, elastic spring and fixed rod, the angle of the up and down fluctuation of the beam is reduced, the time for the beam to stop is reduced, and it is convenient for the operator to read. The practical value is relatively high. High, easy to popularize and use.
