Mechanical electronic scale chassis

Abstract

The invention discloses a mechanical electronic scale chassis, which comprises a display assembly. A main damping rotating shaft is embedded to the bottom of the display assembly; a first connecting shaft is sleeved to the bottom of the main damping rotating shaft; a first shaft sleeve is sleeved to the bottom of the first connecting shaft; an upper force-bearing truss is arranged on the outer part of one side of the first connecting shaft; a first fixed disc is arranged on one side of the upper force-bearing truss; a second fixed disc is arranged on the other side of the upper force-bearing truss; a main centering stud is sleeved in the middle of the second fixed disc; a first balance rod is arranged on one side of the upper force-bearing truss; and a second balance rod is sleeved to thetail end of the first balance rod. In the mechanical electronic scale chassis in the invention, a novel structure is used and a design of multiple sets of balance rods is adopted so that the whole electronic scale is ensured to be located at a horizontal position and the horizontal position of the electronic scale is avoided from deviation; meanwhile, multiple sets of limiting pins are adopted sothat inner components of the electronic scale can be ensured to be completely fixed, thereby avoiding moving and ensuring the accuracy of use of the electronic scale.

Description

technical field [0001] The invention relates to the field of electronic weighing, in particular to a chassis of a mechanical electronic scale. Background technique [0002] Scale is a kind of weighing instrument. It is a tool to measure the mass of objects by using Hooke's law or the principle of lever balance of force. According to the structural principle, it can be divided into three categories: mechanical scale, electronic scale, and electromechanical combination scale. The force transmission conversion system and the display system are composed of three parts. Due to the large amount of electrical equipment used in modern times, electronic scales are also more commonly used. When an object is placed on the weighing pan, pressure is applied to the sensor, and the sensor undergoes elastic deformation. Make the impedance change, and at the same time use the excitation voltage to change, output a changed analog signal, the signal is amplified by the amplifier circuit and ou...

AI Technical Summary

Problems solved by technology

[0003] The price of existing electronic scales is relatively high, and the initial adjustment is relatively complicated. Due to the relatively simple structure of the existing electronic scale chassis, when weighing a large mass, the main body of the electronic scale will be bent, which seriously affects the weighing accuracy of the electronic scale. At the same time, because the existing electronic scales do not have additional support and balance devices when weighing, the electronic scales will lose their horizontal position when they are in use, resulting in serious weighing errors in the electronic scales
