Abstract
The utility model relates to a grade rod supporting frame, in particular to the improvement of field measuring and exploring instruments. The grade rod supporting frame is characterized in that a rule hoop is fixed with a connecting column through a connecting plate, the connecting column is connected with an expansion link through a nut, a grade rod is installed in the rule hoop, a screw bolt spanner is screwed firmly, and thereby a grade rod with the supporting frame is formed. The grade rod supporting frame has the beneficial effects that the fatigue of rule supporting staff can be alleviated, the selection conditions of the rule holding staff can be suitably broaden, the stability and the verticality of the grade rod are increased, and thereby the measuring precision is increased.
Description
Technical field
The utility model belongs to field of measuring technique, relates to the improvement of a kind of field survey, prospecting instrument.
Background technology
Still from start to finish hand steered by the people at the technical levelling pole of measurement of the level at present, support must make the people tired easily for a long time, causes levelling pole understable, thereby causes measuring error to strengthen.
Summary of the invention
The purpose of this utility model is:
A kind of levelling pole support is provided, and it can add levelling pole and can make support flexible and that support, make levelling pole be in vertical steady state (SS) all the time.
The technical solution of the utility model is:
The chi hoop is fixed by web joint and joint pin, and joint pin is connected by nut with expansion link, levelling pole is installed screwed track wrench in the drilling depth hoop, forms the levelling pole of belt supporting frame.
The beneficial effects of the utility model are:
Can alleviate the fatigue of holding up the chi personnel, can suitably relax the alternative condition of holding up the chi personnel, strengthen the stability and the verticality of levelling pole, thereby improve measuring accuracy.
