Example Embodiment

[0029] (Example 1)

[0030] This embodiment is an intelligent two-stage weighing electronic scale, see Figure 1 to Figure 9 As shown, it includes an object carrier 91 for placing the object to be weighed; it is characterized in that it also includes a base 92 arranged below the object carrier and four double-stage scales arranged in the base for supporting the object carrier Heavy sensor 93.

[0031] Each two-stage load cell includes a first mounting seat 1, a first precision weighing sensor 2, a first supporting leg 3, an elastic support 4, a second mounting seat 5, and a second precision weighing sensor 6 which are sequentially crimped and arranged And the second support foot 7.

[0032] On the bottom wall of the first mounting seat, there is an annular guide crimping portion 11 and a first clamping seat 12 located at the center of the guide crimping portion; in this embodiment, the bottom of the guide crimping portion 11 The wall is an annular flat surface, and the top wall of ...

Example Embodiment

[0058] (Example 2)

[0059] This embodiment is basically the same as embodiment 1, the difference is: see Figure 10 to Figure 13 As shown, in this embodiment, the structure and shape of the second-precision load cell, the second supporting leg, and the cover are different from those in Embodiment 1. The second-precision load cell in this embodiment is still provided with a second fixing Section 61, the second force-bearing deformation portion 62, and the second resistance strain gauge 63 provided on the second force-bearing deformation portion for detecting the deformation of the second force-bearing deformation portion; but the second precision in this embodiment The shape of the load cell is similar to the reverse "G" shape, the second fixing part is similar to the "C" shape, and the shape of the second force-bearing deformation part is similar to a smaller "C" shape, and is connected to the second fixing part , The combination forms a reverse "G" shape. The range and accurac...

Example Embodiment

[0063] (Example 3)

[0064] This embodiment is basically the same as embodiment 1, the difference is: see Figure 14 to Figure 17 As shown, in this embodiment, the static contact 91 and the movable contact 92 are no longer provided, the upper part of the outer peripheral wall of the first support leg no longer has the annular crimping part 32, and the lower part is no longer used as the spool part 33.

[0065] In this embodiment, an adjusting hole 35 is provided at the center of the first supporting leg, and a circular connecting column 59 protruding upward from the mounting plate is also provided at the center of the tubular boss 53 of the mounting plate. The center of the top wall of the pedestal is provided with a connecting screw hole 591; the tubular boss and the circular connecting pedestal are enclosed to form an annular limit groove 592; the bottom end of the spring is located in the annular limit groove and abuts on the mounting plate On the bottom, the top of the spring a...

Abstract

The invention discloses an intelligent dual-step electronic weighing scale comprising a carrying plate for placing a to-be-weighed object, a pedestal arranged below the carrying plate, and dual-step weighing sensors that are arranged in the pedestal and are used for supporting the carrying plate. The dual-step weighing sensors consist of first mounting seats, first precision weighing sensors, first supporting legs, elastic supporting elements, second mounting seats, second precision weighing sensors and second supporting legs, wherein the units are arranged successively in a pressing mode. The first mounting seats are provided with guiding and pressing parts; the second mounting seats are provided with mounting plate parts and guiding and supporting parts for transmitting pressures exerted on the guiding and supporting parts to the mounting plate parts. In a free state, the guiding and pressing parts are higher than the guiding and supporting parts. When forces are applied on the first mounting seats, the elastic supporting elements are compressed and the first mounting seats move down; and when the forces exerted on the first mounting seats reach a preset degree, the guiding and pressing parts of the first mounting seats move down and are pressed on the guiding and supporting parts. The dual-step electronic weighing scale has the continuous dual-step ranges and has different precision values in ranges at all steps.

Description

technical field [0001] The invention belongs to the technical field of weighing instruments, and in particular relates to an intelligent double-stage weighing electronic scale. 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, but...
