Abstract

The invention provides a leveling ruler. The leveling ruler comprises a cross rod provided with a slideway and two adjusting components with one ends arranged on the slideway, and each adjusting component comprises a grounding piece used for supporting the corresponding adjusting component and a foot screw; each adjusting component further comprises a screw, a nut arranged on the screw in a sleeving mode and a sliding block arranged on the slideway, one ends of the nuts are connected with the sliding blocks, and one ends of the screws penetrate through the foot screws to be screwed into the grounding pieces; a first leveling bubble is arranged on the cross rod; and when the foot screws rotate, the screws are driven to rotate in the nuts. By rotating the foot screws, the relative position between the screws and the nuts can be adjusted, accordingly the distance from the cross rod to the ground can be adjusted, and thus the purpose of leveling is achieved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a leveling ruler. Background technique [0002] The definition of leveling is to facilitate construction, use a level to measure several control points on a plane to see if they are on a horizontal plane, that is, the elevation is the same. The leveling of today's buildings on the same plane basically uses instruments for leveling, such as levels, spirit levels, level tubes or laser instruments, etc. However, the preparation of the level is too much and too slow, and the data is prone to deviation within a certain range; Equipment such as horizontal pipes cannot observe the precise height difference between two points, and the measurement distance has limitations; the cost of the laser instrument is too high and the accuracy is poor. Therefore, it is necessary to design a new leveling device to improve leveling accuracy. Contents of the invention [0003] An embodiment o...
