Engineering surveying instrument convenient to carry

Abstract

The invention discloses an engineering surveying instrument convenient to carry, and relates to the technical field of engineering surveying. The instrument comprises a detaching box and a supportingplate, a telescopic block is arranged on the bottom of the detaching box in a penetrating manner, the bottom of an inner cavity of the telescopic block is fixedly connected with a first spring, the top end of the first spring is fixedly connected with a connecting rod, the end, away from the first spring, of the connecting rod penetrates the telescopic block and extends to the top of the telescopic block, and clamping rods are fixedly connected to the two sides, extending to an inner cavity of the detaching box, of the telescopic block. The engineering surveying instrument convenient to carryfacilitates detaching and mounting of a user, the user can conveniently carry the instrument during surveying, when the surveying instrument is not used, storage is convenient, the service life of thesurveying instrument is longer, a control board can adjust the surveying angle, during surveying, more convenience is achieved, a buffer frame achieves a buffer effect, damage during surveying of thesurveying instrument can be avoided, due to supporting legs, the surveying instrument is more stable, the surveying result is more precise, and hole grooves and inserting blocks can adjust the heightof the supporting legs.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a portable engineering surveying and mapping instrument. Background technique [0002] Engineering surveying and mapping mainly refers to measuring various information of space and the earth and drawing topographic maps of various information. Taking the shape, size and gravity field of the earth and other planets as the research object, the objects of research and mapping are very extensive, mainly including the surface Various ground features, landforms and underground geological structures, hydrology, mineral deposits, etc., such as mountains, rivers, houses, roads, vegetation, etc., usually before developing a piece of virgin land or carrying out large-scale engineering construction, the topographic map must be measured and drawn by an engineering surveyor , and provide other information before making decisions, planning and design, so surveying and ...
