Description

Technical Field

[0001] The utility model relates to the technical field of engineering surveying, in particular to a leveling staff for engineering surveying. Background Technique

[0002] The leveling staff is a kind of leveling rod. In the early days, most leveling rods were made of wood, which was heavy and had a limited length. During measurement, it was inconvenient to carry. Later, lightweight and high-strength materials such as aluminum alloy were gradually used, and it adopted a tower-type retractable form. According to the measuring leveling staff for convenient fixing in construction engineering with the application number CN213147802U, it has the following features. When it is necessary to use the leveling staff for measurement, first pull the pull rod. The pull rod drives the sliding plate to move along the backing plate, and the limiting block at the lower end of the sliding plate slides along the chute. At this time, the limiting groove plays the role of restricting the moving position of the sliding plate. Then, place the bottom end of the ruler between the fixing plate and the sliding plate, and then release the pull rod. At this time, the sliding plate is pulled by the first spring and moves towards the direction close to the fixing plate. At this time, the sliding plate will fix the ruler between the fixing plate and the sliding plate, achieving the effect of fixing the ruler on the backing plate. Then, buckle the buckle onto the snap rings on both sides of the ruler, and then rotate the two collars. The collars make the two screw rods move away from each other by means of the thread. At this time, the two sliders move away from each other, and the sliders will pull the snap rings by means of the support plate. At this time, the two sides of the ruler are subjected to the same magnitude of pulling force, thus achieving the effect of further fixing the ruler and the backing plate. Among them, the collar plays the role of assisting in rotating the screw rod, solving the problem that the stability of the bottom end of the traditional leveling staff is relatively low. The traditional use method of the leveling staff is to directly rely on manual support of the leveling staff and then read the leveling staff. This wastes manpower, and it is easy to cause measurement errors when manually supporting the leveling staff for reading, thus affecting the measurement accuracy. However, it only limits the bottom end of the leveling staff. When the leveling staff is unfolded, the upper end of the leveling staff is not limited, resulting in the leveling staff being prone to shaking and affecting the engineering surveying work.
