Foldable suite device for measuring density of electronic balance

Abstract

The invention relates to the field of density measurement devices and discloses a foldable suite device for measuring the density of an electronic balance. The foldable suite device comprises a supporting tray, a supporting frame, a sample putting mechanism and / or a buoyancy mechanism, wherein the supporting tray can be arranged on a balance seat of the electronic balance; the supporting frame isin an axial symmetry structure, is connected to the supporting tray and is arranged to be folded or unfolded along a folding line parallel to the supporting tray; in an unfolding state, the gravity center of the supporting frame and a weighing center of the electronic balance are both positioned on a symmetrical center line of the supporting frame; the sample putting mechanism and / or the buoyancymechanism can be arranged on the supporting frame and extends towards the bottom end of the supporting frame along the symmetrical center line of the supporting frame. The foldable suite device disclosed by the invention has the advantages that the space is saved and convenience in carrying is realized; the gravity center of a weighed heavy object can be controlled within a smaller radius area with the weighing center of the electronic balance as a round point, so that a measurement result of the electronic balance is more accurate.

Description

technical field [0001] The invention relates to the technical field of density measuring devices, in particular to a foldable electronic balance density measuring kit device. Background technique [0002] In the application of electronic balance, there is a detection function for the density of the measured object, which is determined by Archimedes principle. When measuring the density of a solid, the weight of the measured object is measured in air and water, and the density of the measured object is calculated using the buoyancy formula; when measuring the density of a liquid, an object with a known volume is used to intrude into the water and measured using a balance The buoyancy force on the intruding object, according to the formula buoyancy F=ρ 液 gv 排 , the liquid density can be measured. Devices with similar functions currently on the market are usually self-contained and mainly supported by a single arm. At the same time, the structural materials are all metal, wh...
