Prism centering rod

Abstract

The invention discloses a prism centering rod which comprises a centering rod and two support rods, wherein the centering rod and the support rod all comprise an outer tube and a telescopic inner tube which is inserted into the outer tube; the outer tube and the inner tube are fixed through handheld type locking pieces; the support rods are connected with the outer tube of the centering rod through a connecting component and have the function of supporting the centering rod; the inner tube of the centering rod is at least sleeved by one connecting sleeve; a support rack for supporting a prism detection piece is arranged at one end of the connecting sleeve; a balance counterweight component is arranged at the other end of the connecting sleeve. The prism centering rod disclosed by the invention has the advantages of simple structure, convenience in operation, high universality and solidness and reliability, not only is simultaneous plotting operation of multiple items of different heights at one same plotting point achieved, but also plotting on different adjacent plotting points of different heights in different directions within certain range that the centering rod is taken as the circle center can be achieved, the time and the labor are saved, the number of operators is reduced, the working efficiency is high, and the plotting result is precise and accurate.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a prism centering rod. Background technique [0002] The centering rod for surveying and mapping is an indispensable centering device in surveying and mapping, and has a wide range of uses in surveying and mapping. It is a retractable metal rod that can directly point to the ground marking point in the vertical direction. [0003] There are many specifications of existing centering rods, generally with different height specifications such as 2.15 meters, 2 meters, 3 meters, 5 meters, etc. Although the existing centering rods have been made into telescopic metal rod structures, their general performance has been improved from the height . [0004] However, the surveying and mapping equipment is all installed on the top of the centering rod, but one centering rod can only perform one surveying and mapping operation. If there are many surveying and mapping ...
