Problems solved by technology

[0002] The leveling rod of the existing surveying and mapping instrument has deficiencies in the measurement process, especially when aligning the leveling bubble, the line of sight cannot be perpendicular to the leveling bubble, and there is a certain inclination angle, which will cause errors, and when the head is lowered to calibrate the bubble During the process, the situation of the surveyor and the vehicle on the road cannot be seen, which not only wastes the measurement time, but also has potential safety hazards, which brings a lot of inconvenience to the work of the surveyor

Abstract

The invention relates to a novel precise invar leveling staff. The novel precise invar leveling staff is provided with a prolate ruler with scales on the front surface; a handle is arranged on one side of the ruler; a leveling bubble is arranged at the back of the ruler; the upper part of the ruler is connected with a sliding sleeve capable of sliding up and down; and the sliding sleeve is positioned at the back of the ruler and is hinged with a reflecting mirror capable of adjusting an angle up and down. The novel precise invar leveling staff has a simple structure and convenient use; a user can conveniently align and calibrate the leveling bubble without lowering the head and can observe the conditions of a road surface and a surveyor on the opposite side at the same time to achieve timely communication; and measuring time is effectively saved and personal safety is ensured.

Description

technical field [0001] The invention relates to an Invar level gauge, in particular to a novel precision Invar level gauge. Background technique [0002] The leveling rod of existing surveying and mapping instruments has deficiencies in the measurement process, especially when aligning the leveling bubble, the line of sight cannot be perpendicular to the leveling bubble, and there is a certain inclination angle, which will cause errors, and when the head is lowered to calibrate the bubble During the process, the situation of the surveyor and the vehicle on the road cannot be seen, which not only wastes the measurement time, but also has potential safety hazards, which brings a lot of inconvenience to the work of the surveyor. Contents of the invention [0003] In order to solve the problems encountered in the use of the existing Invar level gauge, the present invention proposes a new type of precision Invar level gauge. The level gauge is simple in structure and easy to us...
