[0002] A measuring electronic scale refers to a weighing device that uses electronic technology to convert the weight of an object into an electrical signal through a sensor, and displays the weight value in digital form after processing. It is usually composed of a weighing device, a sensor, a display and a power supply. It is commonly used for weighing and pricing of goods in supermarkets, shopping malls, farmers' markets and other places.

They are mainly used in situations where accurate measurement is required, such as commercial trade settlement, laboratory analysis, and pharmaceutical production. In these situations, the accuracy of weight is crucial and is directly related to economic benefits and product quality. However, for some merchants, cheating on electronic scales can make the actual weight of the goods less than the displayed weight.

If damaged, it can be visually checked and handled. When in use, by turning the knob 210, the I-shaped limit block 209 and the adjusting screw 208 are rotated at the same time, and the I-shaped limit block 209 rotates inside the active area 212. The two sides of the I-shaped limit block 209 clamp the active area 212, so the I-shaped limit block 209 will not shake inside the active area 212. Since the adjusting screw 208 and the threaded hole 206 are threadedly rotated, and the adjusting wedge 205 is clamped between the two limiting side plates 215, the bottom of the adjusting wedge 205 At the same time, it is sandwiched between two adjusting ramps 214, so the adjusting wedge 205 will move on the top surface of the adjusting ramp 214 under the rotation of the adjusting screw 208. When the adjusting wedge 205 is close to the active area 212, it will rise, otherwise it will fall. At the same time, the knob 210 will also move up and down. By making the slide bar 203 slide inside the slide groove 202, the adjusting wedge 205 will drive the connecting plate 201 to move up and down at the same time. The connecting plate 201 is fixed to the bottom of the chassis 101. Therefore, by turning the knobs 210 at the four corners respectively, the electronic weighing scale can be adjusted to a balanced state.
