Problems solved by technology
[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 surface of the combination ruler are not on one surface. During the measurement process, the level distance The distance of each combined ruler is inconsistent, which affects the measurement accuracy

Embodiment Construction
[0039] The following is attached Figure 1-7 The application is described in further detail.
[0040] The embodiment of the application discloses a measuring leveling rod.
[0041] refer to figure 1 with figure 2 , the leveling rod includes a plurality of scale bodies 1 nested together, that is, the number of scale bodies 1 is at least two, and the cross-sectional area of each scale body 1 gradually becomes smaller. In this embodiment, the scale body 1 The number is three, and the cross section of each scale body 1 is rectangular.
[0042] In order to facilitate the description of the structure between each scale body 1, two adjacent scale bodies 1 nested together, the inner scale body 1 is called the inner scale body 1, and the outer scale body 1 is called the inner scale body 1. Become the outer scale body 1, and describe it with the leveling rod unfolded.
[0043] refer to figure 1 with figure 2 , one of the outer walls of the outermost ruler body 1 is provided w...

The application relates to a surveying leveling rod and its usage method, belonging to the technical field of construction engineering surveying equipment, which includes a plurality of scale bodies that are nested together step by step. The inner ruler body is called the inner ruler body, and the outer ruler body is called the outer ruler body; the inner ruler bodies all extend out of the outer ruler body, and each of the inner ruler bodies stretches out of the outer ruler body A scale panel is attached to the side wall of the body, and all the scale panels are located on the same side, on the same vertical plane and abutted against each other; the scale panels can be moved closer to or away from the inner scale body , the scale panel and the inner scale body can be received in the corresponding outer scale body. After the leveling rod is unfolded, all the scale panels automatically move to the same vertical plane under the action of the spring, so that the horizontal spans of all the scale distances from the level are more consistent, thereby improving the measurement accuracy of the leveling degree.
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...
