[0002] Existing electronic platform scales such as Figure 1 As shown, the scale frame consists of an upper frame and a lower frame, and the upper frame and the lower frame are welded by components such as rectangular tubes and fixed plates.

The weighing sensor is arranged between the two sensor fixing plates, and two longitudinal tubes need to be respectively arranged on the upper frame and the lower frame, which has high material cost and labor cost.

On the other hand, the setting height and horizontality between the two longitudinal tubes and the setting horizontality of the sensor fixing plate between the two longitudinal tubes are prone to deviations, and uneven force is prone to occur, thereby affecting the weighing accuracy.
