Problems solved by technology

[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.

Embodiment 1

[0017] This embodiment is an adjustable double-stage double-precision load cell, see Figure 1 to Figure 5 As shown, it includes a mounting base 1, a first precision load cell 2, a second precision load cell 3, a support foot 4, an elastic support 5 and an adjustment mechanism 6 for adjusting the height of the elastic support.

[0018] The mounting seat is provided with a mounting plate portion 11 and a force guiding support portion 12 for transmitting the pressure received by itself to the mounting plate portion; an elastic support member, a first precision load cell, a mounting plate portion, and a second precision weighing The sensor and supporting feet are crimped and set in sequence.

[0019] The installation board part is arranged horizontally, the first card holder is arranged on the top wall of the installation board part, and the second card holder is arranged on the bottom wall. The existence of the first deck and the second deck can make the installation operation ...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 6 and Figure 7 As shown, a static contact 123 is set at the top of the force guiding support part, and a moving contact 514 adapted to the static contact is set on the force guiding crimping part of the upper support; when the force guiding crimping part is crimped on the force guiding When it is on the supporting part, the moving contact is crimped and arranged on the static contact, and the two realize electrical connection. In practice, when the moving contact and the static contact are in electrical contact, an electrical signal is generated to the connected external central control circuit. When the central control circuit receives the signal, the second precision load cell measurement is displayed on the display When the central control circuit does not receive the signal, the data measured by the first precision load cell will be displayed on the display screen; that is to say...

Abstract

The present invention discloses an adjustable dual-order and dual-precision weighting sensor. 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 an adjustable double-stage double-precision weighing sensor. 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 can reach 1 gram...
