Problems solved by technology
[0003] There are many problems in the use of balances for physics teaching. For example, some existing balances for physics teaching often have beams that fluctuate up and down during use, and the beams fluctuate up and down for a long time, which affects the operator’s readings and reduces work efficiency. The placement requirements of some physics teaching balances are very high, and some existing physics teaching balances may cause inaccurate measurement results due to uneven placement surfaces

Abstract
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.
Description
technical field [0001] The invention relates to a balance, in particular to a balance for physics teaching, belonging to the technical field of educational equipment application. Background technique [0002] A balance is a kind of weighing apparatus. The balance beam is supported by a fulcrum (axis) at the center of the beam to form two arms. A plate is hung on each arm. An object of known mass is placed in one plate, and an object of known mass is placed in the other plate. Put the object to be measured, and the deflection of the pointer fixed on the beam when it does not swing and points to the middle scale indicates the quality of the object to be measured; the balance is a kind of equal arm lever; the balance is an instrument for measuring the quality of the object; it is based on Made of the principle of leverage, there is a small plate at both ends of the lever, a weight is placed at one end, and an object to be weighed is placed at the other end. There is a pointer i...
