Technical background
At present; LOAD CELLS is widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, vapour inspection line, track scale, and it converts measurable electric signal into through the quality signal with weight, and now the most frequently used be exactly resistance strain weighing transducer; Elastic body deforms under the effect of external force; Make attaching foil gauge above that also in company with deforming, its resistance of foil gauge distortion back changes, and converts changes in resistance into electric signal at last.The Chinese patent notification number is CN201285314Y, and the day for announcing is that the name of the utility model on August 5th, 2009 is called energetically the value side force sensor of weighing, and comprises elastic body, strainometer, can and stressed pressure head; Elastic body is provided with strain bore, and described strainometer is arranged in the strain bore, and can is arranged on the elastomeric outside; Strain bore on the sealing elastomer, elastomeric upper end is provided with installation base, and described stressed pressure head is arranged on the installation base; Though above-mentioned utility model has improved security and reliability of data transmission in survey when being worth energetically; But complex structure, manufacturing procedure and material expend many, and weighing precision is low.
Summary of the invention
The purpose of the utility model is to overcome existing load cell structure complicacy, and the technical barrier that weighing precision is low provides a kind of simple in structure, the LOAD CELLS that weighing precision is high.
The utility model solves through following technical proposals: a kind of LOAD CELLS comprises elastic body, supporting part that is connected with elastic body and the cable that is connected with elastic body; It is characterized in that; Described supporting part bottom sides is along being provided with the last ring groove that opening makes progress, and described elastic body upper surface is provided with annular groove, and annular cover plate is stamped in described annular groove upper end; Described elastic body lower end hollow forms cavity; Described cavity upper surface middle is provided with the circular groove that Open Side Down, and edge, described cavity upper surface is provided with the following ring groove that Open Side Down, and the anchor ring between described ring groove down and the circular groove is pasted with foil gauge.The utility model has adopted loop configuration; Improved the load-bearing capacity of whole LOAD CELLS; Also reduced the use amount of elastomeric material, reduced production cost, gone up ring groove, following ring groove and annular groove simultaneously and all help to improve elastomeric deformability; And following ring groove is kept apart the elastomer portion that foil gauge attached and the sidewall of cavity, reduces elastic body interference to the foil gauge linearity when distortion.
As preferably, the edge of described circular groove bottom surface is provided with and has downward ring groove, and described circular groove sidewall is conical surface-shaped.Improve elastomeric deformability once more.
As preferably, described elastomeric lateral wall is provided with loop concave, and the sidewall thickness at loop concave position is less than the thickness of elastic body lower end sidewall.Form the elastic hinge structure at thick, thin-wall cross-linked position, improve elastomeric deformability, improve weighing precision.
As preferably, described foil gauge has eight, and eight foil gauges evenly distribute around elastomeric central shaft.Help to improve weighing precision.
As preferably, describedly go up ring groove, the xsect of ring groove and ring groove all is U shape down.Increase elastomeric deformability, improve weighing precision.
As preferably, described cable is connected with elastic body through water joint.Water joint plays waterproof, anti-wet goods effect.
Therefore; A kind of LOAD CELLS of the utility model possesses following beneficial effect, and 1, simple in structure, easy for installation; Manufacturing procedure and material use amount have been reduced; 2, improve elastomeric deformability through last ring groove, following ring groove, annular groove, ring groove and loop concave, reduce the linear disturbance of other stress simultaneously, improve weighing precision foil gauge.
