Laser line-projection device

Abstract

A laser line-projection device with a ranging function. The laser line-projection device comprises a support, a suspension system, a laser line-projection module and a laser ranging module, wherein the suspension system is movably connected to the support and the suspension system swings freely with gravity to realize a suspended state; and the laser line-projection module and the laser ranging module are fixedly mounted on the suspension system, the laser line-projection module projects on a plane to form crossed beams which have an intersection point, and an axis of a ranging beam emitted by the laser ranging module passes through the intersection point. The laser line-projection device ensures the consistency of emergent directions of the laser line-projection module and the laser ranging module; moreover, by means of rationally integrating and arranging the positions of laser transmitters in the laser line-projection module and the laser ranging module, an axis of emergent light of the laser ranging module coincides with tile intersection point projected by the laser line-projection module, thus providing convenience for measurement and setting-out processes while the accuracy of measurement is also improved, which is conducive to improving the working efficiency.
