Description

An engineering measuring tripod

technical field

The utility model relates to an engineering measuring tripod.

Background technique

The optical theodolite is the main measuring instrument in civil engineering surveying. It is usually supported by a tripod. At present, it is difficult to accurately control the telescopic range of the tripod legs of the optical theodolite. The telescopic legs often cause large-scale sliding of the legs and displacement of the tripod tip. The problem has brought great inconvenience to the operator. The main reason for such problems is that the existing tripod leg brake screw is designed to be arranged vertically on the telescopic leg surface. When leveling, it is necessary to loosen the leg brake screw and artificially pull the telescopic leg to change the height of the leg. In the circular level bubble sentence, the brake screw of the frame leg is finally tightened, so it is impossible to accurately control the expansion and contraction of the frame leg to achieve the purpose of leveling.

Therefore, it is necessary to provide a new technical solution to overcome the above defects.
