Measurement rod

Abstract

The invention relates to the technical field of shipbuilding equipment and especially relates to a measurement rod. The measurement rod comprises a telescopic measurement rod body and a reflection sheet assembly, wherein the reflection sheet assembly is detachably installed at the upper end of the telescopic measurement rod body, and the reflection sheet assembly comprises a convex reflection sheet, the front surface and the back surface of the convex reflection sheet are each provided with a graduation line, the convex reflection sheet comprises a bottom sheet and a convex sheet, and the convex sheet is arranged at one side of the bottom sheet in the middle. According to the invention, through the convex structure of the reflection sheet assembly, the problem that measurement points are inaccurate because support is lacked and sometimes standing stability cannot be 100% ensured during concrete point measurement is solved, and through the telescopic measurement rod body, the problem that the measurement scope of shipbuilding is restricted to the height of a surveyor and erection of a scaffold is solved. Through the detachably reflection sheet assembly and the telescopic measurement rod body, the structure is simple, the portability is high, the operation is convenient, construction operation and application are facilitated, and the measurement accuracy and the measurement efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding equipment, in particular to a measuring rod. Background technique [0002] Measurement is to use data to describe the observed phenomenon according to a certain law, that is, to make a quantitative description of things. Measurement is the process of quantifying non-quantified objects. [0003] In mechanical engineering, measurement refers to the experimental cognition process of comparing the measured value with a standard quantity with a unit of measurement in order to determine the ratio between the two. [0004] The object of measurement is the measurement object: mainly refers to geometric quantities, including length, area, shape, elevation, angle, surface roughness, and shape and position errors. Since geometric quantities are characterized by a wide variety and various shapes, their characteristics, definitions of measured parameters, and standards must be studied and familiarized i...

Problems solved by technology

[0008] The purpose of the present invention is to propose a measuring rod. Through the structure of the reflective sheet assembly, it solves the problem of inaccurate measuring points due to no support and sometimes not necessarily being able to ensure a stable stand when measuring specific stuck points. Problem, through the telescopic measuring rod body, it solves the problem that the measurement range of shipbuilding is limited by the height of the surveyor and the erection of scaffolding
