Abstract

The invention relates to a non-linear scale specific gravity balance capable of directly weighing the specific gravity of solids of any types, any volumes and any shapes. The balance comprises a pivot and a balance arm, and the balance arm is supported on the pivot. The balance is characterized in the pivot is fixed on a support seat, a counterweight is arranged on the balance arm on the left side of the pivot; the counterweight can be finely tuned toward the left and the right around the position of the counterweight on the balance arm; and a water cup and an object suspension cable device are hung on the balance arm on the right side of the pivot. The pivot consists of a cutting edge which is fixed on the balance arm and takes a triangular prism shape and a line-shaped groove which is fixed on the support seat. The balance has simple and compact structure and integrated functions, and can directly weighs the specific gravity of a solid without the specific value of the weight and the specific value of volume of the measured solid and computation. The balance has simple measurement principle and strong practicability, is a direct embodiment of the lever principle and the Archimedes principle, and can be widely used in laboratories of middle and primary schools as well as ordinary households.

Description

technical field [0001] The invention relates to a non-linear scale specific gravity balance (or density) device, in particular to a device capable of directly weighing any type, volume and shape of non-water-soluble solids. Background technique [0002] In general, when measuring the specific gravity of a solid, first use a weighing device, such as an electronic scale, to weigh the weight of the solid to be measured, then use a measuring cup to measure the volume of the solid, and then use the formula "specific gravity of the object = object The weight of the object ÷ the volume of the object" to calculate the specific gravity of the solid. Because this method involves measuring the weight, volume and calculation formula of solids, the measurement process is cumbersome and complicated. Except for experimenters and schools who use these methods when measuring the specific gravity of solids when doing experiments, ordinary people seldom use them. . [0003] The current speci...
