Patent ID: 8769837

Claim:
A device for marking riding lines for a transport vehicle, comprising: laser-emitting modules 300 adapted to form luminous lines spaced apart from each other by a predetermined distance on the road beside or behind the transport vehicle 100 , each laser-emitting module 300 has a light source-producing unit 310 adapted to produce the luminous line therefrom and a light-guiding unit 320 adapted to adjust the direction of the light produced from the light source-producing unit 310 to induce the formation of the luminous line, the light-guiding unit 320 being formed of a line-forming module adapted to diffuse or collect the light emitted from the light source-producing unit 310 in such a manner as to allow the diffused or collected light to be formed in a shape of the line having a given length along the road; a power supply module 500 adapted to supply power to the laser-emitting modules 300 ; an external housing A adapted to accommodate the laser-emitting modules 300 thereinto; and a fixing module 200 adapted to fix the external housing A to the transport vehicle 100 and having a gripping part 210 fixed to a given position of the transport vehicle and a fixing part 220 insertedly fixed into the gripping part 210 by means of a fixing member 230 , so that the external housing A is moved up and down around the fixing member 230 .
