Description

Technical Field

[0001] The utility model relates to the technical field of steel bar measurement, in particular to a steel bar horizontal weighing and length measuring instrument. Background Art

[0002] During the test of steel bars, it is often necessary to measure the weight and length of the steel bars so that the tested steel bars can be in a more standard form to improve the inspection quality of the test. The existing equipment for detecting the length of steel bars mostly detects the length of the steel bars after limiting the ends.

It is inconvenient to take and place the steel bars, and for testing more steel bars, a single limit point is not convenient for steel bar positioning and support, and it is inconvenient to disassemble and install the steel bars.
