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 double-precision weighing sensor. The adjustable double-precision weighing sensor comprises a first installation base, a first precision weighing sensor, a second installation base, a second precision weighing sensor and an elastic support element, all of which are sequentially connected in a pressing mode. The elastic support element comprises an upper support element, a spring and a lower support element, wherein the top end of the spring is connected to the upper support element in an abutted mode, and the bottom end of the elastic support element is connected to the lower support element in an abutted mode. The second installation base is provided with a force guiding press-connecting part, and the lower support element is provided with a force guiding support part. In a free state, the force guiding press-connecting part is higher than the force guiding support part; when the second installation base bears pressure and is stressed, the second precision weighing sensor compresses the spring, and the force guiding press-connecting part is driven to move downwards; when the second installation base bears pressure and is stressed to a preset degree, the force guiding press-connecting part is downwards moved to be press-connected onto the force guiding support part. The adjustable double-precision weighing sensor has double step continuous ranges, and each step range has different precision values.

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...
