Abstract

The invention relates to a column type elastic body which comprises a fixed portion, a bearing portion and a strain portion. The fixed portion and the bearing portion are arranged on two sides of the elastic body, the strain portion is fixed between the fixed portion and the bearing portion and comprises two ring grooves arranged on the elastic body, strain holes arranged between the two ring grooves, and strain pieces fixed in the strain holes, a sleeve is sleeved at the elastic body of the strain portion, two ends of the sleeve are respectively connected with thin walls outside the ring grooves, an overload protection mechanism formed by bent notches is arranged on one side, facing the bearing portion or / and the fixed portion, of the elastic body of the strain portion, clearances between the bent notches are overload clearances beta, outside notches of the bent notches extend to the periphery of the elastic body, inside notches of the bent notches are communicated with deformation holes outside the strain holes, or the inside notches of the bent notches are communicated with the strain holes. The column type elastic body is good in manufacturability and capable of realizing dynamic weighing safety protection.

Description

technical field [0001] The invention relates to a column type elastic body and belongs to the technical field of electronic weighing instruments. Background technique [0002] In industrial occasions, with the continuous improvement of production efficiency, the requirements for weighing are getting higher and higher. Traditional static weighing can no longer meet the high-speed and high-efficiency requirements of modern industry. It is urgent to solve the problem of high-precision weighing in dynamic occasions. . In dynamic situations, the load cell will be affected by more vibration, impact, extrusion, torsion, etc. [0003] With people's attention to food hygiene, the requirements for dynamic weighing technology are getting higher and higher. Under dynamic applications, the load cell is required to have a high ability to resist overload. Furthermore, due to the particularity of the food industry, the load cell is required to be easier to clean to meet the requirements o...
