Abstract
Description
Technical Field
[0001] The utility model relates to a detection device, in particular to a detection device for measuring a steel ruler. Background Art
[0002] When measuring a steel ruler, the "0" mark on the end edge should be used as the measurement reference. In this way, it is not only easy to find the measurement reference during measurement, but also convenient for reading and counting; when measuring, the steel ruler should be placed flat and straight, with the scale facing up and outward, and should not be tilted forward and backward or left and right, otherwise, the number read from the ruler will be larger than the actual size measured; when reading, the line of sight must be perpendicular to the ruler surface to avoid errors in the reading: the measured plane must be flat, otherwise the measured number is not the actual size of the measured part. Before using the steel ruler, check whether all parts of the steel ruler are damaged, and no appearance defects that affect the performance are allowed, such as bends, scratches, broken lines, or unclear scale lines; steel rulers with hanging holes must be wiped clean with clean cotton thread after use, and then hung up to allow them to droop naturally. The above-mentioned prior art has problems in the detection of measuring steel rulers of different sizes; the problem of inaccurate calibration of measuring steel rulers due to usage time, wear and tear, etc. often occurs.
