Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a flatness measuring device. Background Art

[0002] During the processing of plates and platforms, it is necessary to measure the flatness of the plates and platforms. Plates and platforms with large areas need to be measured at multiple positions and points using a level to measure the flatness of the surfaces of the plates and platforms. However, using a traditional level to measure the plates not only requires the operator to bend down and squat to place the level on the surface of the plates and platforms for measurement, but also is difficult to operate and inconvenient to detect the surfaces of large areas of plates and platforms. In addition, it is difficult to measure the slope of the plates and platforms for calculation using a traditional level. For this reason, we propose a flatness measuring device.
