Abstract

The invention provides an elastic body of a load cell and a weighing system, including a base, a vertical plate, an action frame, a cantilever elastic plate, a pressure plate, a guide rail, a support frame, a spring and an auxiliary deformation component, and the vertical plate is arranged on the base. The action frame is located on the base and forms a moving pair in the vertical direction. The action block at the bottom of the action frame is in contact with the end of the cantilever elastic plate. between. When the pressure plate moves down, the inclined-plane-shaped end will contact the support frame, and then push the support frame to move outward, so that the support frame moves in the direction close to the cantilever elastic plate, and then the support frame can withstand the deformation of the cantilever elastic plate when the deformation is too large. The cantilever elastic plate avoids inelastic deformation of the cantilever elastic plate caused by excessive load, and the auxiliary deformation component deforms when the deformation of the cantilever elastic plate is too large, so as to realize the effect of auxiliary support and measurement.

Description

technical field [0001] The invention relates to the technical field of weighing, in particular to an elastic body of a weighing sensor and a weighing system. Background technique [0002] The publication number is CN2903934, which discloses a cantilever beam load cell. The arrangement of the strain holes is asymmetrical to the thickness of the upper and lower walls of the elastic body, and there is a stress barrier between the bottom plane of the elastic body's lower strain zone and the bottom plane of the fixed end. groove, the stress-blocking groove is set at 90° to the axial length direction, the upper strain region of the elastic body is provided with a concave surface for installing a working circuit, and the strain gauge is arranged on the upper strain region. [0003] In the above-mentioned prior art, the elastic body will undergo elastic deformation during weighing, and then the strain gauge resistor will generate an electrical signal, but the elastic body will be da...
