Abstract

The invention discloses a range finder. By arranging a gear, a detection ring, an inner ring, an outer ring, a resistance tape, a lead hammer and an electric conductor, when a support rod rotates to drive the gear to rotate, the gear drives the inner ring to rotate through the detection ring, the relative position between the electric conductor at the lower end of the lead hammer and the resistance tape is changed, the resistance value, between the resistance tape and the electric conductor, measured by a resistance measurement instrument is changed, and the rotating angle of the support rod is calculated; and by arranging an inner rod, an outer rod, a measurement body and a resistance strip, when a telescopic rod in the support rod stretches or shrinks, the relative position between the inner rod and the outer rod is changed, the position of the measurement body on the resistance strip is changed, the resistance, between the resistance tape and the electric conductor, measured by theresistance measurement instrument is changed, the length of the support rod is calculated, the angle of the range finder is adjusted, and the automatic leveling is realized.

Description

technical field [0001] The invention belongs to the technical field of civil engineering surveying and mapping, and in particular relates to a distance measuring instrument. Background technique [0002] The range finder is a commonly used instrument in civil engineering surveying and mapping. When using the range finder, it can measure the horizontal distance and the oblique distance. On the basis of leveling, fine-level the rangefinder. During the leveling, you need to observe the position of the horizontal bubble and gradually adjust the rangefinder to the level. The calibration process is slow; [0003] Aiming at this problem, Chinese patent CN207471063U discloses a kind of total station type electronic range finder bracket. The bottom leg adopts a telescopic tripod, which is characterized in that the top of the tripod is fixed with a cloud platform, and the platform includes a base and a support plate, wherein: a flange bearing is arranged in the center of the base, an...
