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）

[0028] This embodiment is a kind of double-precision weighing electronic scale with adjustment mechanism, see Figure 1 to Figure 8 As shown, it includes a carrier plate 91 for placing objects to be weighed, a base 92 arranged under the carrier plate, and four double-precision load cells 93 arranged in the base for supporting the carrier plate.

[0029] Each double-precision load cell includes a first mount 1, a first-precision load cell 2, a second mount 3, a second-precision load cell 4, and an elastic support 5 that are sequentially crimped; the elastic support includes an upper A 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 .

[0030] The bottom wall of the first mounting seat is provided with a first card seat 11, and the top ...

Embodiment 2）

[0053] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 11 to Figure 12 As shown, since the adjusting screw is surrounded by the second mounting seat and the lower support, it cannot be rotated again after the overall assembly, so the adjusting mechanism in this embodiment also includes an adjusting screw cover 61 and a top screw cover 62; The outer peripheral wall of the support is provided with an outwardly convex stopper 533, and the outer peripheral wall of the force-guiding crimping part is provided with an external thread area 311; 611, the inner wall of the upper part is provided with an internal thread area 612 adapted to the external thread area of ​​the force-guiding crimping part; The screw cap is also screwed on the external thread area of ​​the force-guiding crimping part, located above the adjusting screw cap, and abuts against the adjusting screw cap; under the action of external force, the stopper part can Slip up and down ...

Embodiment 3）

[0056] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 13 to Figure 16 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 seat is bonded and fi...

Abstract

The invention discloses a double-precision weighing electronic scale with an adjustment mechanism, which comprises a loading board for placing objects to be weighed, a base arranged under the loading board, and a board for supporting the loading board arranged in the base The double-precision load cell; each double-precision load cell includes the first mount, the first precision load cell, the second mount, the second precision load cell and the elastic support that are sequentially crimped; the elastic support It includes an upper support, a spring and a lower support. The top end of the spring abuts on the upper support, and the bottom end of the elastic support abuts on the lower support; There is a force-guiding support part; in the free state, the force-guiding crimping part is higher than the force-guiding support part; when the second installation seat is under pressure, the spring is compressed by the second precision load cell, which then drives the crimping part to move down , when the second installation seat bears pressure to a preset level, the force-guiding crimping part moves down to be crimped on the force-guiding supporting part. The invention has two-stage continuous measuring ranges, and has different accuracy values ​​in each ordering range.

Description

technical field [0001] The invention belongs to the technical field of weighing instruments, and in particular relates to a 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 precision value can reach 1 gr...
