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

[0026] This embodiment is an adjustable combined weighing electronic scale, see Figure 1 to Figure 8 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 combined scales for supporting the object plate arranged in the base Heavy sensor 93.

[0027] Each combined load cell includes a mounting seat 1, a first precision load cell 2, an elastic support 3, a second precision load cell 4, a support foot 5 and an adjustment mechanism 6 for adjusting the overall height of the elastic support; The supporting member includes an upper supporting member 31, a spring 32 and a lower supporting member 33, 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 mounting seat, the first precision weighing The sensor, the upper supporting part, the spring, the lower support...

Embodiment 2

[0050] This embodiment is basically the same as the above-mentioned embodiment 2, the difference is: see Figure 9 to Figure 12 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 of the first force-bearing deformation part. The amount of 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 Based on a smaller "C" shape, it is connected with the first fixing part to form a reverse "G" shape. The range and accuracy of this first precision load cell are the same as those in Embodiment 2, and this structure can also be made by stamping, and its manufacturing process is simpler. The bottom of the mounti...

Embodiment 3

[0053] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 13 to Figure 16 As shown, in this embodiment, the guide strut 313 is no longer arranged on the bottom wall of the connecting plate portion of the upper support. In this embodiment, an adjustment hole 315 is provided at the center of the connecting plate, and a circular connecting column 334 protruding upward from the mounting plate is provided at the center of the tubular boss of the lower support. There is a connecting screw hole 335 at the center of the top wall; the tubular boss and the circular connecting column form an annular limiting groove 336; the bottom end of the spring is located in the annular limiting groove and abuts against the mounting plate of the lower support On the top wall of the upper support, the top end of the spring abuts on the bottom wall of the upper support.

[0054] This embodiment includes an adjustment mechanism 6 for adjusting the height of the spring...

Abstract

Disclosed in the invention is an adjustable combined weighing sensor comprising a carrying plate, a pedestal, and four combined weighing sensors. The four combined weighing sensors that are arranged in the pedestal and are used for supporting the carrying plate consist of mounting seats, first precision weighing sensors, elastic supporting elements, second precision weighing sensors, supporting legs, and adjusting mechanisms for adjusting the overall heights of the elastic supporting elements. The elastic supporting elements include upper support elements, springs, and lower support elements; and the mounting seats, the first precision weighing sensors, the upper support elements, the springs, the lower support elements, the second precision weighing sensors, and the support legs are arranged successively in a pressing mode. The upper support elements are provided with guiding pressing parts; and the support legs are equipped with guiding supporting parts. In a free state, the guiding pressing parts are higher than the guiding supporting parts; when forces are applied on the upper support elements to reach a preset degree, the guiding pressing parts move down and then are pressed on the guiding supporting parts. The 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 adjustable combined 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 ...
