Bracket for folding surveying and mapping instrument

Abstract

The invention provides a foldable support for a surveying and mapping instrument. The support comprises a centering rod I, a centering rod II and a support rod, wherein the centering rod I and the centering rod II vertically arranged to be parallel and of equal height, the centering rod I is connected with the support rod through an articulated beam I, the centering rod II is connected with the support rod through an articulated beam II, the support rod rotarily passes through the end parts of the articulated beam I and the articulated beam II, and the top of the support rod is provided with a surveying and mapping instrument connecting seat. The foldable support is applicable to installation of a surveying and mapping instrument with great weight, has a simple structure and can be conveniently carried after folding.

Description

technical field [0001] The invention relates to a bracket for a foldable surveying and mapping instrument, which belongs to the technical field of surveying and mapping equipment. 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. 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 . However, the surveying and mapping instruments are all installed on the top of the centering rod, and only one surveying and mapping instrument can be assembled on the top of a centering rod; O...

AI Technical Summary

Problems solved by technology

However, the surveying and mapping instruments are all installed on the top of the centering rod, and only one surveying and mapping instrument can be assembled on the top of a centering rod; Other support frames cannot guarantee its stability well, which will affect the accuracy of the overall surveying and mapping results

At present, although some combined support frames appear on the market to overcome the above-mentioned defects of the single centering rod, such combined support frames are often too large to be carried and transported.
