The elastic body comprises a fixed part and a strain part, wherein the strain part comprises a strain hole, strain beams and a deformed slotted hole arranged between the two strain beams; the deformed slotted hole positioned on the strain part is provided with two spacing holes, axial lines of the spacing holes present 90 degrees plus or minus 5 degrees together with axial lines of the strain beams; the front ends of the spacing holes extend into the fixed part; in addition, the spacing holes and the deformed slotted hole are intersected, pin shafts are arranged in the spacing holes and are closely matched with the spacing holes of the fixed part, the pin shafts and the spacing holes of the strain part are in clearance fit, and the clearance in radius is between 0.05 mm and 1.5 mm. The elastic body is not only provided with an upper spacing and a lower spacing on the vertical forced direction, but also can effectively resist the horizontal force, realizes multidirectional protection, has favorable torsion-resistance property, achieves weighing safety protection under the dynamic state, and is applicable to the rapid weighing mensuration under the dynamic occasion.
Description
Technical field
The utility model relates to a kind of elastic body of 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 simple in structure, can realize the elastic body of the 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 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: the described distortion slotted eye place that is positioned at the strain part has two spacing holes, the axis of spacing hole and the axis of strain beam are 90 ° ± 5 °, the front end of spacing hole extends into fixed part and intersects with the distortion slotted eye, bearing pin is installed in the spacing hole, the spacing hole of bearing pin and fixed part closely cooperates, the spacing hole of bearing pin and strain part is a clearance fit, and monolateral gap is between 0.05～1.5mm.
The utility model is provided with two pivot pins on elastomeric strain part; the axis of this pivot pin and the axis of strain beam are 90 ° ± 5 ° settings; because an end of this two pivot pin cooperates with elastic body fixed part tightening seal; pivot pin is connected elastomeric fixed part reliably; and there is the gap in the elastic body of part pivot pin and strain part; make the elastic body of strain part and another part of pivot pin form a protection gap; simple in structure; reliably; 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 this bearing pin, reduce the distortion after elastic body impacts.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.
