Problems solved by technology

[0004] However, each component in the existing laser rangefinder is produced by division of labor, and the errors generated during production are inevitable, which makes the assembled rangefinder have errors of varying degrees, such as the existence of non-parallel laser light emitted or distance measurement. The reflected laser received by the instrument is not the strongest reflected laser, etc., which affects the accuracy of the distance test result of the rangefinder to the test object, and the test effect is poor

Abstract

The invention discloses a laser ranging device, comprising a body and an object lens assembly, a prism assembly, an eye lens assembly, a receiving lens assembly and an emission module which are arranged on the body, wherein the body is provided with a first port, a second port and a third port; the wall surfaces of the first port and the third port are respectively provided with a first skewed slot and a third skewed slot; the object lens assembly is sleeved in the first port; a first dowel on the outer surface of the object lens assembly is correspondingly buckled in the first skewed slot and stretches out of the wall surfaces of the ports; the receiving lens assembly is sleeved in the third port; a third dowel on the outer surface of the receiving lens assembly is buckled in the third skewed slot and stretches out of the wall surfaces of the ports; the emitted laser becomes parallel light by sliding the first dowel to change and adjust the displacement of the object lens assembly; the strongest reflected laser is received by sliding the third dowel to change and adjust the displacement of the receiving lens assembly, thus more accurately measuring the distance of the measured objects and improving the ranging accuracy.

Description

technical field [0001] The invention relates to the technology in the field of range finders, in particular to a laser range finder that can be adjusted to improve test accuracy. Background technique [0002] In addition to direct measurement with a ruler, the existing distance measurement method also includes the method of using a pole to measure with an instrument, and calculating the corresponding angle to calculate the distance. However, because the length of the ruler is limited, the ruler method is not suitable for long-distance measurement. The disadvantage of using a pole to measure with an instrument is that one person needs to insert the pole and another person controls the instrument, so this method is time-consuming. In the measurement of long distances, this method is inconvenient and prone to large errors. [0003] In recent years, the laser distance measurement method has been widely used in distance measurement, and the laser distance meter has also become a...
