[0002] Highway maintenance and construction traffic safety guidance devices refer to safety warning signs, markings, lights and other facilities set up during highway maintenance and construction to ensure the safety of the construction site and smooth traffic. The main function of these devices is to remind drivers and pedestrians of the existence of the construction site, guide them to pass through the construction area safely, and avoid traffic accidents. The existing highway maintenance and construction traffic safety guidance devices can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] Most of the road maintenance and construction traffic safety guidance devices widely used on the market are fixedly installed, and the guide signs are installed at the construction location. However, in actual use, not only does it take a lot of time to fix the position of the guide signs, but also because the construction site is full of dust, it is easy for dust to be adsorbed on the surface of the guide signs, forming an obstruction on the surface of the guide signs. It is also necessary to manually clean the guide signs regularly, which is labor-intensive. For this reason, we propose a road maintenance and construction traffic safety guidance device to solve the above problems. Utility Model Content

[0014] 2. The utility model installs laterally movable limit rods on both sides of the cross bar. When the cleaning cotton on the cross bar needs to be replaced, the two sets of shift blocks can be pushed toward each other, so that the two sets of movable blocks can drive the two sets of limit rods to move toward each other along the movable inner cavity. The two sets of return springs are squeezed and deformed by the movable blocks to accumulate force. When the two sets of limit rods completely leave the limiting holes on the first positioning column and the second positioning column, the connection between the sleeve and the first positioning column and the second positioning column can be released. Then the cross bar can be pulled forward to allow the cross bar to drive the cleaning cotton to complete the disassembly, which is convenient for quickly replacing and disassembling the cleaning cotton on the cross bar, ensuring that the cleaning cotton can effectively clean the surface of the guide display board.
