Abstract

The invention relates to a measuring leveling rod and a using method thereof, and belongs to the technical field of constructional engineering measuring equipment, the measuring leveling rod comprises a plurality of rod bodies which are sleeved together step by step, in every two adjacent rod bodies, the rod body sleeved with the inner side is called as an inner rod body, and the rod body sleeved with the outer side is called as an outer rod body; the inner ruler body extends out of the outer ruler body, a scale panel is attached to the side wall, extending out of the outer ruler body, of each inner ruler body, and all the scale panels are located on the same side, located on the same vertical plane and connected together in an abutting mode. The scale panel can move close to or away from the inner ruler body, and both the scale panel and the inner ruler body can be contained in the corresponding outer ruler body. After the leveling rod is unfolded, all the scale panels automatically move to the same vertical plane under the effect of springs, so that the consistency of transverse spans between all the scales and the leveling instrument is high, and the measurement precision of the levelness is improved.

Description

technical field

[0001] The application relates to the field of construction engineering surveying equipment, in particular to a surveying leveling rod and a method for using the same. Background technique

[0002] The leveling rod is used in conjunction with the spirit level to measure the level. Most of the rulers are made of wood, glass fiber reinforced plastic or aluminum alloy. Among them, the tower ruler is a socketed combination ruler, its length is between 3-5m, and it is connected by two or three sections. When in use, the internal combination ruler can be pulled out, and the measurement can be carried out, and the measurement is completed. Finally, the extracted combined ruler is retracted inside to reduce the volume of the entire tower ruler, which is convenient for the surveyor to carry.

[0003] However, since each combination ruler is nested together, the surfaces of different combination rulers are not on the same vertical plane, that is, the scales on the sur...
