Description

Technical Field

[0001] The utility model relates to the technical field of level rods, in particular to a level rod capable of adjusting its angle. Background Art

[0002] Surveying and mapping is a highly comprehensive professional technology, which mainly involves the technology and activities of measuring and depicting various objects and phenomena. A level rod is needed in the process of surveying and mapping. A level rod is a ruler used for leveling, and is mainly used to measure the height difference between two points on the ground, so as to calculate the elevation of an unknown point. The level rod is mainly used in the fields of construction and machinery, and because of its high precision and versatility, it has become an indispensable and important tool in measurement tasks.

[0003] Some existing levels have certain defects during use. The main reason is that their angles cannot be adjusted during use. This is because the level is designed only to measure and mark height or distance, and angle adjustment is not a core function. However, this will ultimately lead to a certain limitation in the measurement range and increase the difficulty of measurement in some areas. Therefore, technical personnel in this field provide a level with adjustable angle to solve the problems raised in the above background technology. Utility Model Content

[0008] Furthermore, a plurality of rectangular through holes are provided on the front surface of the level ruler body, and a horizontal tube is fixedly connected to one side surface of the plurality of rectangular through holes;

[0009] Through the above technical solution, the main function of the rectangular through hole is to serve as a connecting medium between the level tube and the level ruler body, and the main function of the level tube is to determine whether the level ruler is in a horizontal state.

[0010] Furthermore, a shift rod is fixedly connected to a surface of one side of the first gear column;

[0011] Through the above technical solution, the first gear body can be shifted under the action of the shifting rod, so that the first gear column and the second gear column can be separated.

[0018] Furthermore, the protective coating includes an anti-rust coating, and the upper end surface of the anti-rust coating is fixedly connected with a wear-resistant coating;

[0019] Through the above technical scheme, the anti-rust coating can achieve an anti-rust effect, and the wear resistance of the surface of the level ruler body and the movable ruler body can be improved under the action of the wear-resistant coating.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model provides an angle-adjustable level ruler. When the angle of the level ruler body needs to be adjusted, the lever is first moved to move the first gear column to the depth of the fixed cylinder, and then the angle of the movable ruler body is adjusted. The lever is then released, and the first gear column is restored to its original state under the action of a limit spring. In this way, the first gear column and the second gear column can be matched, thereby limiting and fixing the movable ruler body after rotation. In this way, the angle of the level ruler body can be adjusted, thereby improving the measurement accuracy, reducing the error generated during measurement, and improving the measurement efficiency.

[0022] 2. The utility model proposes an angle-adjustable level ruler. Under the action of a magnetic handle, an ink line that is arranged to rotate around the surface of a roller can be pulled out to the inside of a movable ruler body. Then, the module is used to mark the places to be marked. Then, under the action of a rocker, the marked ink line is recovered into the inside of the movable ruler body. In this way, the operation can be simplified to a certain extent, so that complicated equipment and calibration process are not required. The size and position of the building can be better clarified through the ink line, and the accuracy and consistency of the surveying and mapping data can be ensured to a certain extent. At the same time, the use cost can be reduced by using the ink line. BRIEF DESCRIPTION OF THE DRAWINGS
