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）

[0022] This embodiment is a double precision load cell, see Figure 1 to Figure 6 As shown, it includes the first mounting base 1, the first precision load cell 2, the second mounting base 3, the second precision load cell 4, the elastic support 5 and the overall height adjustment of the elastic support, which are sequentially crimped. The adjustment mechanism 6; the elastic support includes an upper support 51, a threaded spring 52 and a lower support 53. The top end of the spring abuts on the upper supporting member, and the bottom end of the elastic supporting member abuts on the lower supporting member; the lower supporting member is provided with a force guiding support portion 531 .

[0023] The bottom wall of the first mounting seat is provided with a first card seat 11, and the top wall of the first mounting seat has a plane for bonding and fixing on the bottom wall of the external loading plate; the first precision load cell is provided with The first fixed part 21, ...

Embodiment 2）

[0045] This embodiment is basically the same as the above-mentioned embodiment 1, the difference is: see Figure 7 to Figure 10 As shown, the first precision load cell in this embodiment is still provided with a first fixing part, a first force-bearing deformation part, and a sensor set on the first force-bearing deformation part for detecting the deformation amount of the first force-bearing deformation part. The first resistance strain gauge; but the shape of the first precision load cell in this embodiment is similar to the reverse "G" shape, its first fixed part is similar to "C" shape, and the shape of the first force-bearing deformation part is similar to A smaller "C" shape is connected with the first fixed part to form a reverse "G" shape. The measuring range and accuracy of this first precision load cell are the same as those in Embodiment 1, and this structure can also be made by stamping, and its manufacturing process is simpler. The bottom of the first mounting se...

Abstract

The invention discloses an adjustable dual-precision weighing sensor comprising a first mounting seat, a first precision weighing sensor, a second mounting seat, a second precision weighing sensor and an elastic supporting part. The above-mentioned units are arranged successively in a compressing mode. The elastic supporting part consists of an upper supporting part, a spring and a lower supporting part; the top end of the spring is abutted against the upper supporting part; and the bottom of the elastic supporting part is abutted against the lower supporting part. The second mounting set is provided with a guiding pressing part; and the lower supporting part is provided with a guiding supporting part. In a free state, the guiding pressing part is higher than the guiding supporting part. When a force is applied on the second mounting seat, the second precision weighing sensor compresses the spring and thus the guiding pressing part is drive to move down; and when the second mounting seat reaches a preset degree under the force, the guiding pressing part moves down to the guiding supporting part. The adjustable dual-precision weighing sensor has a dual-step continuous range; and different precision values are set in all steps of ranges.

Description

technical field [0001] The invention belongs to the technical field of weighing sensor structure design, and in particular relates to an adjustable 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 even smaller...
