A photoelectric angle measuring device

Abstract

The invention discloses a photoelectric type angle measuring device, and relates to the technical field of angle measurement. The photoelectric type angle measuring device comprises a box body and a bottom cover. The bottom of the bottom cover is rotatably connected with an annular base, and a positioning device is fixed to the peripheral side surface of the box body. A lase emitter and a luminometer are separately fixed to one opposite inner wall of the box body, and an optical filter assembly is rotatably connected to the top of the inner wall of the box body through a hinge seat. The optical filter assembly comprises a optical filter, and a fixing ring is fixed to the peripheral side surface of the optical filter. According to the photoelectric type angle measuring device, the box bodyis rotated through the cooperation of a limiting block, a limiting notch, a sliding rod and an annular notch, the angle to be measured again is selected through the relative positions of a scale ringand a scale, the relative positions of the bottom cover and the annular base are limited through the positioning device, angle values of different angles of an object can be quickly and accurately measured, and the problem that the measurement is inaccurate after the measurement angle of an existing angle measuring device is changed is solved.

Description

technical field [0001] The invention belongs to the technical field of angle measurement, in particular to a photoelectric angle measurement device. Background technique [0002] Angle measurement is divided into horizontal angle measurement and vertical angle measurement. Horizontal angle measurement is used to determine the plane position of ground points, and vertical angle measurement is used to indirectly determine the elevation of ground points and the distance between points. [0003] The traditional angle measuring device can only measure the angle in a single direction when measuring, which has the limitation of measurement. When measuring other angles, the direction of the measuring device needs to be rotated. When the angle is converted, the error of the angle data will be generated and the angle is uncontrollable , resulting in inaccurate measurement data, which is not convenient for users to use.
