[0022] Working principle:

[0023] When the present invention is used, after the device is placed at the construction site, the content recorded on the corresponding screen 22 is displayed in the observation window 49 according to the requirements of the construction site. When adjusting the content displayed in the observation window 49 on the screen 22, the vertical plate 30 is first moved toward the mounting plate 27 by pulling the pull rod 39 by hand, so that the rack 35 is separated from the gear 25 at the end of the winding roller 21. At this time, the gear 25 can be rotated by the crank 26, and the gear 25 drives the winding roller 21 to rotate synchronously. When the lower winding roller 21 is rotated counterclockwise, the lower winding roller 21 pulls the upper winding roller 21 to rotate. The curtain is wound on the square winding roller 21, and the lower winding roller 21 is performing the winding work, so that the content of the curtain 22 wound on the upper winding roller 21 can be displayed on the observation window 49. Similarly, when the upper winding roller 21 is rotated clockwise, the upper winding roller 21 is performing the winding work, and the content of the curtain 22 wound on the lower winding roller 21 can be displayed on the observation window 49. Therefore, the present invention can have the function of displaying a variety of different warning slogans and warning symbols through the arrangement of two winding rollers 21 and the curtain 22, so the present device can be applied to a variety of different construction sites. After adjusting the content displayed in the observation window 49 of the curtain 22, the hand holding the pull rod 39 is pulled and the pressing plate 41 is pressed at the same time, so that the pressing plate 41 moves toward the vertical plate 30, so that the push rod 42 pushes the square guide cylinder 43 to move toward the stopper 33. As the pressing plate 41 is continuously pushed, the pressing block 44 pushes the stopper 33. At this time, the two racks 35 move in opposite directions to each other, and the second spring 34 is squeezed by the stopper 33. At this time, the vertical plate 30 is pushed forward, so that the rack 35 meshes with the gear 25. At this time, the hand holding the pull rod 39 and pressing the pressing plate 41 is released. In this way, the rack 35 is meshed with the gear 25 under the action of the first spring 29. 35 will be tightly meshed with the gear 25. Under the action of the second spring 34, the upper rack 35 is always subjected to the downward force of the second spring 34, so that the upper rack 35 will mesh with the upper gear 25 to provide a clockwise rotational force. Similarly, the lower rack 35 is always subjected to the upward force of the second spring 34, so that the lower rack 35 will mesh with the lower gear 25 to provide a counterclockwise rotational force, thereby making the curtain 22 between the two winding rollers 21 in a tensioned state. Therefore, the curtain tensioning structure 48 can effectively prevent the curtain 22 between the two winding rollers 21 from loosening and drooping.

[0024] When adjusting the direction of the observation window 49, the first positioning pin 6 is pulled out, and the conical turntable 3 can be rotated by the second U-shaped handle 18, so that the direction of the observation window 49 can be adjusted 360 degrees at will, and after the second positioning pin 13 is pulled out, the sleeve 9 can be rotated by the first U-shaped handle 15, so that the elevation direction of the observation window 49 can also be adjusted at will. By setting the lighting lamp 20, light can be provided to the observation window 49 at night, providing a field of vision for vehicles and pedestrians driving at night to see the warning signs.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
