Abstract

An overturn-preventive weighing module comprises a column type weighing sensor. The module is characterized in that the upper and lower ends of the column type weighing sensor are connected with upper and lower connecting plates via upper and lower bearing pressure heads respectively, the lower connecting plate is provided with a limiting sleeve, the column type weighing sensor is arranged in the limiting sleeve, the upper end of the limiting sleeve abuts against a rubber sleeve which sleeves the upper bearing pressure head, a scale body plate is arranged on the upper connecting plate, and the scale body plate is connected to the lower connecting plate via limiting rods. The overturn-preventive weighing module is simple in structure, convenient to install and low in cost, can be used to solve problems in limiting and overturn prevention of the column type weighing sensor effectively, and ensures that an electronic weighing apparatus works safely and accurately.

Description

technical field [0001] The invention belongs to the technical field of weighing sensors and relates to an anti-tilt weighing module, which is specifically applied to various electronic weighing fields. Background technique [0002] Electronic weighing instruments are composed of a scale body, a load cell and a weighing instrument. Among them, the column type load cell is widely used due to its high measurement accuracy, large range and compact structure. [0003] The column load cell is generally a double-spherical rocker structure. If the scale body does not have a reliable limit device, the entire scale body will be in an unstable state, the sensor will swing too freely, and even a serious accident of the scale body overturning will occur. Therefore, electronic scales such as large-scale truck scales and tank scales will consider the limit of the scale body, and large-height tank scales should also consider anti-overturning design to ensure that the electronic scales can w...
