Problems solved by technology
In use, it is often necessary to adjust the height of the telescopic rod to adjust the position of the prism. At present, the telescopic rod is usually fixed by bolt clamping. The plastic knob on the outside of the bolt is worn out after long-term use, making it difficult to turn later, and the bolt itself is easy. Due to long-term wear and tear, the slippery wire often causes inconvenient adjustment of the centering rod in engineering practice, which affects the measurement efficiency

The invention belongs to the technical field of engineering surveying, and particularly relates to a centering rod for leveling, which comprises a supporting rod, a centering rod and a centering rod, the at least one telescopic rod is arranged at the upper end of the supporting rod in a sliding manner; the prism rod is arranged at the upper end of the at least one telescopic rod in a sliding manner, and the prism rod is used for mounting a prism; the top of the supporting rod and the top of the at least one telescopic rod are each provided with a locking mechanism, the top of the supporting rod and the top of the at least one telescopic rod are each provided with a notch, and the locking mechanisms are used for tightening the top of the supporting rod and the top of the at least one telescopic rod. The prism is installed through the prism rod, then the sharp part at the bottom of the supporting rod is inserted into the ground so that the prism can be perpendicular to an underground target point, the top of the supporting rod and the top of at least one telescopic rod are tightened through the locking mechanism, and therefore the movable telescopic rods and the prism rod are locked and fixed so that measurement can be completed.
Description
technical field [0001] The invention belongs to the technical field of engineering survey, and in particular relates to a centering rod for leveling survey. Background technique [0002] As an indispensable centering device in surveying and mapping, the surveying and mapping centering rod has a wide range of uses in surveying and mapping. When the existing centering rod is working, the lower end of the centering rod is used to align the tip of the centering rod with the target point to be measured, and the two support rods are adjusted to center the circular blister. Since the centering rod is vertical, the prism group on the centering rod Plumb to the subsurface target point. In use, it is often necessary to adjust the height of the telescopic rod to adjust the position of the prism. At present, the telescopic rod is usually fixed by bolt clamping. The plastic knob on the outside of the bolt is worn out after long-term use, which makes it difficult to turn later, and the b...
