Background technology
Strain gauge load cell is for dynamometry under static, dynamic condition or again, and in China, industrial processes detect
Widely applied with fields such as control, automatic gauges.Reflect in the market after the weighing sensor actual use on small weighbridge,
Tensile strength is inadequate, weighs inaccurate, and stability is poor, unreasonable due to designing, i.e., the spacing between installation through-hole too close to, with
When claiming body fixation, tensile strength is inadequate so that weighting platform face cracky, kinetic energy resistance to compression is poor, and it is poor that numeral is stablized, and effect is very not
It is good.
Utility model content
The purpose of this utility model is to provide a kind of strain gauge load cell and weighbridge, is claimed with solving traditional strain-type
Retransmit the technical problem of sensor installation strength difference.
In order to solve the above-mentioned technical problem, the utility model provides a kind of strain gauge load cell, including：
In the elastomer of cuboid；The side of the elastomer is provided with first, second installation through-hole being disposed adjacent, with
And the center spacing of first, second installation through-hole is 30 ~ 31mm；Being suitable to by first, second installation through-hole should
Variant weighing sensor, which is arranged on, to be claimed on body.
Further, do not opened up in the elastomer and positive and negative strain regions are symmetrically arranged with the two sides of installation through-hole, it is described
Positive and negative strain regions are the circular groove suitable for placing strain gauge element.
Further, the opposite side of the elastomer offers the 3rd peace of the spike for claiming body load-bearing table top suitable for installation support
Through hole is filled, the 3rd installation through-hole is set in the same direction with first, second installation through-hole.
Another aspect, the utility model additionally provide a kind of weighbridge, are provided with foregoing strain gauge load cell.
Further, the weighbridge is provided with some equally distributed strain gauge load cells, and each strain weighing passes
First, second installation through-hole of sensor is fixedly connected with the bottom plate of weighbridge；3rd installation through-hole of each strain gauge load cell
Equipped with the spike suitable for installing weighbridge load-bearing table top.
The beneficial effects of the utility model are that strain gauge load cell of the present utility model is by the way that first, second is pacified
Center spacing between dress through hole is set as 30 ~ 31mm, and the distance increases the cantilever force of strain gauge load cell, so as to add
Strong strain gauge load cell and claim the installation strength between body；Strain gauge load cell stability of the present utility model
Height, dynamic property are good, it is not easy to damage, have obvious performance advantage in farming and animal husbandry.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
