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 switch, a power module and a load cell for supporting the loading board. When the weight of the 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 measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g. The error is relatively large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing the weight, especially it cannot be used as a kitchen electronic scale.
And the existing kitchen electronic scale, its indexing value can reach 1 gram, but its measuring range generally does not exceed 50 kilograms, so can not be used as weighing scale
At present, there are also electronic scales with a division value of 2 grams and a range of 150 kg on the market. They are made of force sensors with high precision and a large range, but they are very expensive and cannot be popularized.

Abstract

The invention discloses an improved double-precision electronic scale, which includes a loading board, a first precision weighing assembly for supporting the loading board, a second precision weighing assembly for supporting the loading board and the first precision weighing assembly. The weight assembly, and the force guide for transmitting the pressure it receives to the second precision weighing assembly; the first precision weighing assembly includes an elastic support; the force guide includes a load bearing with a support hole and a crimping plate area Plate, and four placement parts fixed on the bottom wall of the load-bearing plate; in the free state, the force-guiding crimping part of the loading plate is higher than the guiding support part of the force-guiding piece; when the loading plate carries objects, the loading plate The elastic supporting part is pressed down under force to move down, and after the loading plate is stressed to a certain extent, its force-guiding crimping part is crimped on the force-guiding support part of the force-guiding part. In addition to serving as both an electronic weight scale and a kitchen electronic scale, the present invention can effectively prevent the kitchen electronic scale from being damaged when the weight of the loaded object exceeds the maximum range of the kitchen electronic scale.

Description

Technical field [0001] The invention belongs to the technical field of electronic scale structure design, and specifically relates to an improved double-precision electronic scale. Background technique [0002] The weight electronic scales currently on the market mainly include a load board, a display screen, an adjustment switch, a power module, and a load cell for supporting the load board. Its function is mainly used for weighing the human body, and is generally used for weighing the human body. When the weight of the weighing object exceeds the preset value, the display screen starts 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 graduation value is 100 grams. Therefore, this traditional electronic weight scale cannot be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale. However, the existing electronic kitchen s...
