Description

Technical Field

[0001] This utility model relates to the field of material gauge length technology, and mainly to a gauge length device. Background Technology

[0002] In the field of construction engineering, when tensile strength tests are required on materials (steel bars, steel pipes, etc.), elongation is an important indicator for measuring the mechanical properties of materials. The usual practice for measuring the gauge length of materials is to set the specified gauge length with vernier calipers and then mark it on the material, or to use a gauge length measuring instrument. However, when using vernier calipers, there is a certain degree of human error in setting the gauge length, which causes certain problems in the evaluation of results, especially in the processing of critical data. In addition, existing gauge length measuring instruments can only perform fixed-length tests on steel bars.

[0003] Chinese utility model patent with announcement number CN220932000U discloses a rebar gauge to solve the problems mentioned above, such as the certain human error when using vernier calipers, and the fact that existing rebar gauges can only detect rebars of fixed lengths.

[0004] However, in implementing the aforementioned rebar gauge, the inventors discovered at least the following problems: Only two groups of steel bars can be marked at a time, resulting in low work efficiency.

[0005] It is not suitable for gauge length of steel bars with uneven lengths, and it does not have a weighing function, so its function is relatively simple. Utility Model Content
