Abstract

The invention provides an elastic body of a weighing sensor and a weighing system, and the elastic body comprises a base, a vertical plate, an acting frame, a cantilever type elastic plate, a pressing plate, a guide rail, a supporting frame, a spring and an auxiliary deformation assembly; the vertical plate is arranged on the base, and the acting frame is located on the base and forms a moving pair in the vertical direction; an acting block at the bottom of the acting frame makes contact with the end of the cantilever type elastic plate, the two auxiliary deformation assemblies are oppositely arranged, and the auxiliary deformation assemblies are arranged between the base and the acting frame. When the pressing plate moves downwards, the inclined-face-shaped end can make contact with the supporting frame, then the supporting frame is pushed to move outwards so that the supporting frame can move in the direction close to the cantilever type elastic plate, and therefore, when the deformation amount of the cantilever type elastic plate is too large, the supporting frame can abut against the cantilever type elastic plate, so the situation that the cantilever type elastic plate generates inelastic deformation due to overlarge load is avoided; the auxiliary deformation assembly deforms when the deformation quantity of the cantilever type elastic plate is overlarge, and the auxiliary supporting and measuring effects are achieved.

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...
