Abstract

The invention relates to a ranging device, which comprises a body, a receiving lens, a first locking wheel, a second locking wheel, a movable plate and a receiving component, wherein the body is provided with a first end and a second end; the first end is opposite to the second end, and the second end is provided with at least one guide rod; the receiving lens is connected to the first end of the body; the first locking wheel and the second locking wheel are connected to the second end of the body in a rotary mode; the movable plate is sleeved on the guide rod of the second end of the body in a movable mode and is arranged between the first locking wheel and the second locking wheel; and the receiving component is connected to the movable plate and is used for receiving light beams received by the receiving lens. The movable plate moves through the rotation of the first locking wheel and the second locking wheel so as to drive the receiving component to move on an optical axis.

Description

technical field [0001] The present invention relates to a distance-measuring device, in particular to a distance-measuring device capable of easily adjusting the receiving component to a proper focus and optical axis position. Background technique [0002] In general, there are various forms of distance measuring devices currently on the market. For example, a laser ruler is a distance measuring device. [0003] The laser ruler mainly includes a laser light source, a transmitting lens, a receiving lens and a receiving component. When the laser ruler is used for distance measurement, the laser light source will emit a 650nm red laser, and the red laser will be collimated by the emitting lens into an approximately parallel laser beam. Then, when the laser beam strikes a target object, diffuse reflection will occur, and the receiving lens can receive the reflected laser beam and focus it on the receiving component. Then, the laser beam received by the receiving component can...
