Description

The elastic body of integral type LOAD CELLS

Technical field

The utility model relates to a kind of elastic body of integral type LOAD CELLS, belongs to the electronic scale technical field.

Background technology

In industrial occasions, also more and more higher to the requirement of weighing along with improving constantly of production efficiency, traditional static weighing can not adapt to modern industry high speed, requirement efficiently, presses for the high-precision weighing problem of solution in dynamic case.Therefore influences such as under the dynamic case, LOAD CELLS can be subjected to more vibration, impact, push, reverse have higher requirement to the autoprotection of LOAD CELLS.And present disclosed LOAD CELLS has caused the very fast damage of LOAD CELLS owing to lack protection.Especially in weighing of low capacity used, because the LOAD CELLS sensitive beam of low capacity is thinner, just easier damage under this dynamic environment.

Summary of the invention

The purpose of this utility model provides a kind of elastic body that can realize the integral type LOAD CELLS of the dynamic safeguard protection of weighing down.

The utility model is that the technical scheme that achieves the above object is: a kind of elastic body of integral type LOAD CELLS, comprise fixed part and strain part, the Response Division branch comprises strain bore, strain beam and the distortion slotted eye between two strain beams, it is characterized in that: described going up is out of shape slotted eye and is out of shape the both sides up and down that slotted eye is symmetricly set on strain bore respectively down, has the upper limit beam that is connected with elastic body in the last distortion slotted eye, be out of shape down and have the lower limit beam that is connected with elastic body in the slotted eye, the upper limit beam has the last skew notch that runs through the upper limit beam section, have the following skew notch that runs through the lower limit beam section on the lower limit beam, the last skew notch of upper limit beam is opposite with the following skew notch direction of lower limit beam, angle α between the vertical cross-section of the last skew notch of upper limit beam and the following skew notch of lower limit beam and strain bore is at 10 °～80 °, angle β between the last skew notch of upper limit beam and the following skew notch of lower limit beam and the parallel cut of strain bore horizontal axis is at 10 °～80 °, and the following skew notch gap of the last skew notch of upper limit beam and lower limit beam is between 0.05～0.5mm.

The utility model has been set up the spacing beam up and down that links to each other with elastic body elastomeric the distortion up and down in the slotted eye; and the skew notch up and down on the spacing up and down beam is as a protection gap; because two skew notch directions are opposite up and down; and the vertical cross-section of skew notch and strain bore and strain bore parallel axes cross section have a certain degree; when elastic body affords up or down power from the horizontal force of any direction of horizontal direction and vertical direction; can limit elastomeric deflection by two skew notches up and down; reduce the distortion after elastic body impacts, and simple in structure; reliably.Elastic body of the present utility model not only vertically is being subjected to have upper and lower spacing effect on the force direction simultaneously; and can effectively resist horizontal force; realized multidirectional protection; has good torsional property; the safeguard protection of weighing under realizing dynamically is applicable to the rapid weighing metering under dynamic case.
