Dual-order and dual-precision weighting sensor with adjustment mechanism

Abstract

The present invention discloses a dual-order and dual-precision weighting sensor with an adjustment mechanism. The sensor comprises a soleplate, a first precision weighting sensor, a second precision weighting sensor, a support leg, an elastic supporting piece and an adjustment mechanism configured to adjust the height of the elastic supporting piece; the soleplate is provided with an installation plate potion and a guiding force support part configured to transmit the pressured to the installation plate portion; the elastic supporting piece, the first precision weighting sensor, the installation plate portion, the second precision weighting sensor and the support leg are arranged in crimping state in order; and the top end of the elastic supporting piece at the free state is higher than the top end of the guiding force support part, and the top end of the elastic supporting piece is moved downwards when being forced and stressed. The dual-order and dual-precision weighting sensor with the adjustment mechanism has dual-step continuous measuring range and has different precision values in each-step range.

Description

technical field [0001] The invention belongs to the technical field of weighing sensor structure design, and in particular relates to a double-stage double-precision weighing sensor with an adjustment mechanism. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can not be used for other purposes except weighing the body on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its precision value...

[0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale.

However, the existing kitchen electronic scales have an accuracy of 1 gram or even less, but their range generally does not exceed 10 kilograms, so they cannot be used as weighing scales.
