Dual-step double-precision electronic weighing scale having adjusting mechanism

Abstract

The invention discloses a dual-step double-precision electronic weighing scale having an adjusting mechanism. The electronic weighing scale comprises a carrying plate for placing a to-be-weighed object, a pedestal arranged below the carrying plate, and dual-step double-precision weighing sensors that are arranged in the pedestal and are used for supporting the carrying plate. All dual-step double-precision weighing sensors consist of mounting seats, first precision weighing sensors, second precision weighing sensors, supporting legs, elastic supporting members and adjusting mechanisms. The mounting seats are provided with mounting plate parts and guiding and supporting parts for transmitting pressures to the mounting plate parts; the elastic supporting members, the first precision weighing sensors, the mounting plate parts, the second precision weighing sensors, and the supporting legs are arranged successively in a pressing mode. The tops of the elastic supporting members are higher than the tops of guiding and supporting parts in a free state and move down when forces are applied on the tops of the elastic supporting members. The dual-step double-precision electronic weighing scale has the dual-step continuous ranges and has different precision values in ranges at all steps.

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 electronic scale 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 preci...

[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.
