Angle-adjustable electro-optical distance measuring instrument

Abstract

The invention discloses an angle-adjustable electro-optical distance measuring instrument. The angle-adjustable electro-optical distance measuring instrument comprises a distance measuring instrumentand reflectors; the distance measuring instrument comprises a base, a first horizontal table surface, a second horizontal table surface, a rotating adjusting shaft rotationally connected on the secondhorizontal table surface, a rotating output shaft rotationally connected on the first horizontal table surface and a control device, wherein the first horizontal table surface and the second horizontal table surface are located on the base. According to the angle-adjustable electro-optical distance measuring instrument, the rotating output shaft and the rotating adjusting shaft are arranged, anda light emitting device and a light receiving device are installed on the rotating adjusting shaft; when manual adjustment needs to be carried out, the rotating output shaft and the rotating adjustingshaft are mutually separated under the effect of the control device, and the rotating adjusting shaft can be freely rotated at this moment; when rotating adjustment needs to be carried out, the rotating output shaft is driven to rise to the portion engaged with the rotating adjusting shaft, and the rotating output shaft is in mutual transmission connection with the rotating adjusting shaft at this moment; the rotating output shaft is driven to rotate through a driving device, electric rotating is achieved, and therefore the problems existing in the prior art are effectively solved.

Description

technical field [0001] The invention relates to an angle-adjustable photoelectric distance measuring instrument. Background technique [0002] The photoelectric rangefinder, also known as the speed of light rangefinder, is an instrument that uses modulated light waves for precise distance measurement. The measurement range can reach about 2.5 kilometers, and it can also be used for night operations. There are many types of photoelectric range finders, among which infrared range finders are developing most rapidly. The principle of photoelectric ranging is: when measuring the distance between two points, place a rangefinder at one point to be measured, and place a reflector at the other point. When the rangefinder emits light to the reflector, it is reflected by the reflector and returns to the instrument. [0003] The photoelectric range finder in the prior art is composed of a range finder and a reflector. In order to accurately find the position of the reflector, the ran...

Problems solved by technology

[0003] The photoelectric range finder in the prior art is composed of a range finder and a reflector. In order to accurately find the position of the reflector, the range finder is usually set to a rotatable structure. Usually, it can be set to manual rotation or electric rotation. Using manual rotation, the adjustment is simple and convenient; while using electric rotation, the adjustment is accurate, but not convenient enough
