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] The present embodiment is an adjustable two-stage weighing electronic scale, see Figure 1 to Figure 9 As shown, it includes a carrier plate 91 for placing objects to be weighed; it is characterized in that: it also includes a base 92 arranged under the carrier plate and four double-stage scales for supporting the carrier plate arranged in the base Heavy sensor 93.

[0029] Each double-stage load cell includes a first mount 1, a first precision load cell 2, a first support foot 3, an elastic support 4, a second mount 5, and a second precision load cell 6, which are sequentially crimped. And the second supporting foot 7.

[0030] On the bottom wall of the first mounting seat, there is provided with an annular force-guiding crimping portion 11 and a first card seat 12 located at the center of the force-guiding crimping portion; in this embodiment, the bottom of the force-guiding crimping portion 11 The wall is an annular plane, and the top wall of the first installation...

Embodiment 2）

[0057] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 10 to Figure 13 As shown, in this embodiment, the structural shape of the second precision load cell, the second support leg and the cover is different from that of Embodiment 1, and the second precision load cell in this embodiment is still provided with a second fixed part 61, the second force-bearing deformation part 62, and the second resistance strain gauge 63 arranged on the second force-bearing deformation part for detecting the deformation amount of the second force-bearing deformation part; but the second precision in this embodiment The shape of the load cell is similar to the reverse "G" shape, its second fixed part is similar to "C" shape, and the shape of the second force-bearing deformation part is similar to a smaller "C" shape, and it is connected with the second fixed part , combined to form a reverse "G" shape. The measuring range and precision of this second precisi...

Embodiment 3）

[0062] 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 moving contact 92 are no longer provided, and the upper part of the outer peripheral wall of the first support leg is no longer provided with the annular crimping part 32, and the lower part is no longer used as the sliding column part 33.

[0063] In this embodiment, an adjustment 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. There is a connecting screw hole 591 at the center of the top wall of the pillar; the tubular boss and the circular connecting pillar form an annular limiting groove 592; the bottom end of the spring is located in the annular limiting groove and abuts against the mounting plate On the part, the top end of the spring abu...

Abstract

The invention discloses a double-order weighing electronic scale. The double-order weighing electronic scale comprises an object carrying plate used for carrying an object to be weighed, bases arranged under the object carrying plate and double-order weighing sensors which are arranged in the bases and used for supporting the object carrying plate; each double-order weighing sensor comprises a first installing seat, a first precision weighing sensor, a first support foot, an elastic supporting part, a second installing seat, a second precision weighing sensor and a second supporting foot which are sequentially connected in a pressed mode, wherein the first installing seat is provided with a force guiding press-connecting part, the second installing seat is provided with an installing plate part and a force guiding supporting part used for transmitting the pressure borne by the second installing seat to the installing plate part, the force guiding press-connecting part is higher than the force guiding supporting part in a free state, the first installing seat compresses the elastic supporting part to move downwards when the first installing seat bears the pressure, and when the first installing seat bears the pressure to a preset degree, the force guiding press-connecting part of the first installing seat moves downwards to be connected to the force guiding supporting part in a pressed mode. The double-order weighing electronic scale has the double-order continuous measuring range and has different precision values in all orders of the measuring range.

Description

technical field [0001] The invention belongs to the technical field of weighing instruments, and in particular relates to a 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 its measurin...
