Description

Technical Field

[0001] The utility model relates to the technical field of geometric measuring tools, and particularly relates to a geometric measuring tool for metrological detection. Background Technique

[0002] Geometric measuring instruments are a kind of tools, applicable to the design and detection technology of mechanical product parts. Metrological detection is a process of obtaining a certain result through a series of repeated tests on the corresponding parameters of the metrological object. In physics, it is usually a process of using a measuring instrument to measure a certain tool to obtain a correct result. A measuring tool is the abbreviation of a physical measuring tool. It is an instrument with a fixed form when in use, used to reproduce or provide one or more known quantity values of a given quantity.

[0003] The prior art patent document with the publication number CN211401018U provides a geometric measuring tool for metrological detection, including a measuring scale. One side of the measuring scale is movably connected with an adjusting plate. A sliding groove is opened on one side of the adjusting plate. The inner wall of the sliding groove is movably connected with a sliding block. One side of the sliding block is fixedly connected with one side of the measuring scale. A through hole is opened at the bottom of the measuring scale. The inner side wall of the measuring scale is fixedly connected with a bearing. The inner wall of the bearing is fixedly connected with a screw rod. A first bevel gear is fixedly connected to the outer wall of the screw rod. The outer wall of the first bevel gear is movably connected with a second bevel gear. The inner wall of the second bevel gear is fixedly connected with a rotating shaft. A rotating handle is fixedly connected to the bottom of the rotating shaft. This geometric measuring tool for metrological detection can achieve the purpose of convenient adjustment, enable the measuring scale to measure a longer length, and can also be adjusted up and down, with a wider application range, meeting people's usage requirements.

[0004] However, in the process of using the existing geometric measuring tools for metrological detection, due to different measurement requirements, multiple measurement methods are needed. Since the measurement methods of geometric measuring tools are too single, when measuring, it is impossible to meet the measurement according to the measurement requirements, resulting in the problem of poor practicability of the geometric measuring tools for metrological detection. For this reason, we propose a geometric measuring tool for metrological detection. Content of the Utility Model
