Problems solved by technology
[0002] Leveling is to measure the height difference between different points in a certain position, and to measure the levelness of a certain surface. However, under some special working conditions, the shape of the surface that needs to be measured for levelness is special, and there is no space for the traditional straight leveling rod to be placed. No, so measuring the levelness of this surface becomes a problem

Abstract
The invention discloses an arc-shaped leveling ruler. The arc-shaped leveling ruler comprises a ruler rod, an elastic sheet, an adjusting column and leveling bubbles, wherein the elastic sheet is in astrip shape; the adjusting column is vertically connected with the ruler rod; the adjusting column is assembled with a threaded hole in the ruler rod through a thread section of the adjusting column;the adjusting column comprises a central adjusting column and two end adjusting columns, and the adjusting column is connected with the elastic sheet at the same time; the connecting positions of theend adjusting columns and the ruler rod and the end adjusting columns and the elastic sheet are positioned on the two sides of the connecting positions of the central adjusting column and the ruler rod and the central adjusting column and the elastic sheet; and the leveling bubbles comprise a first leveling bubble which is positioned on the adjusting column and is arranged in parallel with the adjusting column, and further comprises a second leveling bubble which is arranged on the ruler rod and is arranged in parallel with the ruler rod. According to the arc-shaped leveling ruler, the bending degree of the elastic sheet is changed by adjusting the adjusting columns through knob to be adapted to contact with tested planes of different shapes, so that the universality is strong, the elastic pieces are in direct contact with the tested planes, and the accuracy is high.
Description
technical field [0001] The invention relates to the field of measuring tools, in particular to an arc-shaped leveling rod. Background technique [0002] Leveling is to measure the height difference between different points in a certain position, and to measure the levelness of a certain surface. However, under some special working conditions, the shape of the surface that needs to be measured for levelness is special, and there is no space for the traditional straight leveling rod to be placed. No, so measuring the levelness of such surfaces becomes a problem. Contents of the invention [0003] The problem to be solved by the present invention is to provide an arc-shaped leveling rod, which can change the bending degree of the elastic piece by adjusting each column of the knob, so as to adapt to the contact of the measured plane of different shapes, has strong versatility, and the elastic piece is in direct contact with the measured plane , with high accuracy. [0004] I...
