Land surveying and mapping measuring instrument with angle adjusting function

Abstract

A territorial surveying and mapping measuring instrument with an angle adjusting function belongs to the technical field of surveying and mapping instruments and comprises a first calibration plate and a measuring piece, the measuring piece comprises a scale plate and a second calibration plate, a second limiting piece is mounted on the first calibration plate, a first limiting block is arranged on the second limiting piece, and a second limiting block is arranged on the first limiting block. The right side of the first limiting block is fixedly connected with a second limiting block, the side, away from the first limiting block, of the second limiting block is obliquely arranged, the second limiting piece further comprises a second bottom plate, and a groove is formed among the first limiting block, the second limiting block and the second bottom plate. Wherein the first limiting block and the second limiting block form a groove, the arrangement of the groove can further realize the limiting of the scale plate, and the groove formed by the first limiting block and the second limiting block can facilitate the stability of the scale plate when the scale plate slides in the second limiting piece; therefore, the measuring efficiency of the measuring instrument in the angle measuring process is further enhanced.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping instruments, in particular to a surveying instrument for land surveying and mapping with an angle adjustment function. Background technique [0002] At present, with the continuous development of the construction industry, many measuring devices need to be used in engineering construction to measure the angle of the building. Generally, when automatic equipment is used for measurement, the measured angle can be directly read, and the measurement is more accurate. However, the measuring equipment is not easy to carry, so a low-cost measuring tool is needed to measure the angle of the building, and at the same time, the accuracy of the measurement must be ensured. [0003] In the prior art, the patent with the application number of CN202020145054.8 provides an angle measuring ruler, including a first clamping block, a first locking screw, a base ruler, a main ruler, a fan-shaped base, ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a measuring instrument for land surveying and mapping with an angle adjustment function, through the setting of the first limiter and the second limiter, to solve the problem of frequent rotation in the above background technology that causes the wear of the measuring ruler , resulting in shaking, which reduces the measurement efficiency of the measurement process
