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 switch, 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 measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this kind of traditional weight

Example Embodiment

[0055] (Embodiment 1): This embodiment is a double precision electronic scale, see Figure 1 to Figure 10 As shown, it includes an object carrier 1, a display screen 11, an adjustment switch 12, four first-accuracy weighing components for supporting the object carrier 2, and four first-accuracy weighing components for supporting the object carrier and The second-precision weighing assembly 3, and four force guides 4 for transmitting the pressure it receives to the second-precision weighing assembly.

[0056] In this embodiment, the specific structure of the second-precision weighing assembly 3 is as follows: including a holder 34 with a receiving slot 33 and a card slot, a second-precision load cell 31 arranged in the card slot, and a second The supporting leg 32 on the precision load cell 31, the reed cover 35 covering the bottom opening of the accommodating groove 33 and having a central positioning hole 351; the supporting leg 32 in this embodiment includes a cylindrical metal ...

Example Embodiment

[0066] (Embodiment 2): This embodiment is basically the same as Embodiment 1, the difference is: see Figure 11 to Figure 13 As shown, the force guide member 4 in this embodiment and the holder 34 in the second precision weighing assembly are integrally made by injection molding. Compared with Embodiment 1, the force guide member in this embodiment is no longer separate The bottom wall 41 is provided, but the top wall of the holder 34 is directly used as the bottom wall 41 of the force guiding member in the first embodiment.

[0067] In addition, the specific structure of the first-accuracy weighing assembly in this embodiment is as follows: it includes a mounting seat 27 provided with a card slot and an accommodating cavity, and an opening that covers the bottom of the accommodating cavity in the mounting seat and has a central through hole. The elastic cover 28, the first precision load cell 22 located in the accommodating cavity and clamped in the slot, and the elastic support ...

Example Embodiment

[0070] (Example 3)

[0071] This embodiment is basically the same as embodiment 1, the difference is: see Figure 14 to Figure 18 As shown, this embodiment also provides a square bearing plate 5 with four circular support holes 51 on the top end of the tubular supporting wall in the force guiding member. The bearing plate is used as the guiding force supporting portion of the guiding member in this embodiment. 40. The bottom wall of the carrier plate is still used as the guiding force crimping portion 10.

[0072] In this embodiment, in a free state, the upper support 212 of each elastic support passes through the corresponding support hole 51 and is glued and fixed on the bottom wall of the carrier board, so that the guiding force pressing portion 10 of the carrier board is higher than The guiding force supporting portion 40 of the guiding member; when the weight of the object on the loading board exceeds a certain level, the loading board is moved down and pressed on the bearing ...

Abstract

An electronic scale includes a loading plate (1), a first precision weighing assembly (2) for supporting the loading plate (1), a second precision weighing assembly (3) for supporting the loading plate (1) and the first precision weighing assembly (2), and a force-guiding member (4) for transmitting itself pressure to the second precision weighing assembly (2). The first precision weighing assembly (2) includes an elastic support member (21). A force-guiding support part (40) is arranged on the force-guiding member (4). A force-guiding pressure welding part (10) is arranged on the loading plate (1). When there is no object on the loading plate (1), the force-guiding pressure welding part of the loading plate (1) is higher than the force-guiding support part (40) of the force-guiding member (4). When there are some objects on the loading plate (1), the loading plate (1) is stressed to press the elastic support member (21) to move down. After the loading plate (1) is stressed to a certain degree, the force-guiding pressure welding part (10) presses the force-guiding support part (40) of the force-guiding member (4). When the weight of the loaded objects exceeds the metre full scale of a kitchen electronic scale, the inventive electronic scale effectively prevents damage to the kitchen electronic scale besides the electronic scale is used as a weight electronic scale and the kitchen electronic scale at the same time.

Description

technical field [0001] The invention belongs to the technical field of electronic balance structure design, and in particular relates to an electronic balance. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment switch, 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 measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this traditional body weight electronic scale can not be used as other things except for weighing body weight on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its graduation value can reach 1 gram, but its measuring range is...
