Problems solved by technology
[0002]The measurement of deflection or unevenness of components is often encountered in engineering. For larger components, we often use theodolite and level or other special measurement methods However, most of the existing deflection measurement methods have the problems of inconvenient use and low measurement accuracy; especially the level instrument is difficult to operate when measuring small rods, and the measurement accuracy is difficult to control
Therefore, the existing deflection measurement method is still not ideal enough to meet the needs of use

The invention discloses a method for measuring deflection and its convenient measuring instrument for deflection. When a dial indicator or a micrometer is used to measure the deflection of a component to be measured, the central part at the bottom of the dial indicator or the micrometer is provided with a table tip, and the two sides of the dial indicator or the micrometer are provided with an adjustable arm whose length can be adjusted. The front end of each adjustable arm is provided with a foot. When the measuring instrument is in use, the two feet are closely attached to the surface of the component to be measured or the vertical rod part and the table tip at the central part of the dial indicator or the micrometer abuts closely against the flat surface or the vertical rod of the component to be measured. When the length distance between two feet is L and the number indicated by the dial indicator or the micrometer is V, then the deflection of the component can be obtained as V. According to the invention, it is possible to solve the technical problem that the measuring operation of the deflection or the unevenness in a project is difficult and the precision is difficult to control. The instrument is convenient in use, high in accuracy, portable for carriage, convenient for field measurement, and simple to operate.
Description
technical field [0001] The invention relates to a deflection measuring method and a convenient deflection measuring ruler, belonging to the technical field of deflection measurement. Background technique [0002] It is often encountered in engineering to measure the deflection or unevenness of components. For larger components, we often use theodolite, level or other special measurement methods to measure, but most of the existing deflection measurement methods exist The problems of inconvenient use and low measurement accuracy; especially the operation of the level gauge to measure small rods is difficult, and the measurement accuracy is difficult to control. Therefore, the existing deflection measurement method is still not ideal enough to meet the needs of use. Contents of the invention [0003] The object of the present invention is to provide a deflection measurement method and its convenient deflection measuring ruler, to provide a tool with high measurement accurac...
