Abstract
The invention discloses a tray balance. The tray balance comprises a foundation, a suspension bracket and a knife rest, wherein the middle portion of the foundation is provided with a horizontal ruler, a lower end of the suspension bracket is provided with a vertical supporting arm, the vertical supporting arm is a leading screw, an upper end of the vertical supporting arm is provided with a nut, the nut is in rotatable connection with the vertical supporting arm, the middle portion of the suspension bracket is provided with a scale, the middle portion of the knife rest is provided with an edge, the suspension bracket and the scale are in rotatable connection, one side of the scale is provided with a rider, an upper end of the suspension bracket is provided with a tray, an upper end of the knife rest is provided with an index dial, a lower end of the index dial is provided with a pointer, an upper end of the pointer is provided with a magnifier, and the magnifier is fixedly connected with the pointer. The tray balance is advantaged in that the tray balance in an idle static mode can effectively protect the edge, a measurement result is convenient to acquire, and the measurement result is accurate.
Description
technical field [0001] The invention relates to a pallet balance. Background technique [0002] A balance is an instrument for weighing the mass of an object. Commonly used are analytical balances, physical balances, student balances, tray balances, etc. Physical balances, student balances, and tray balances are commonly used in middle school physics laboratories. It is made according to the principle of "equal". It is mainly composed of swimming codes, scales, balance nuts, bottom plates, indexing plates, beam pointers, heavy vertical lines, etc. [0003] Pallet balance, a weighing tool commonly used in laboratories, is composed of a tray, a beam, a balance nut, a scale, a dial, a pointer, a knife edge, a base, a scale, a swimming weight, and a weight. Its structure is as follows: the balance beam is supported by the fulcrum at the center of the beam to form two arms, and a plate is hung or supported on each arm, and an object of known weight is placed in one of the plate...
