Description

Technical Field

[0001] The utility model relates to the field of weighing sensors, in particular to an elastic body of a weighing sensor. Background Art

[0002] The elastic body of the traditional beam type weighing sensor includes a cross beam in the middle and fixed parts at both ends of the cross beam, and there is an elastic cavity in the middle of the cross beam. In the prior art, the elastic body of the beam type weighing sensor is relatively large in size, and the fixed ends are all solid bodies, which requires more man-hours to process, consumes more materials, and has high production costs. Utility Model Content

[0003] The utility model aims to provide a braking resistor to solve the above problems.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A weighing sensor elastomer comprises an elastomer, an elastic cavity is arranged in the middle of the elastomer, deformation beams are arranged at the upper and lower ends of the elastic cavity, strain gauges are installed on the deformation beams, a flexible circuit board is connected between the strain gauges, the elastic cavity has fixed ends on the left and right, cavities are arranged on the fixed ends, a plurality of fixing holes are arranged on the fixed ends, a wire hole is also arranged on the fixed ends, and a column is arranged between the cavity and the elastic cavity.

[0006] Optionally, a through hole is provided on the column, and the through hole is used to accommodate the flexible circuit board.

[0007] Optionally, the flexible circuit board is installed on the outside of the column.

[0008] The beneficial effects of the utility model are:

[0009] 1. The cavity at the fixed end not only reduces the material usage of the elastomer, but also reduces the drilling depth when machining the fixing hole at the fixed end, thereby reducing material costs and improving processing efficiency.

[0010] 2. The through holes on the columns are used to pass through the flexible circuit boards, which makes the overall appearance more beautiful and the flexible circuit boards are not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS
