[0024] As a technical optimization solution of the present utility model, a lifting mechanism 8 is set up, and the first bevel gear 82 is driven to rotate by starting the motor 81, and then the first bevel gear 82 drives the second bevel gear 83 to rotate through the meshing connection, and then the second bevel gear 83 drives the screw 84 to rotate, so that the screw 84 drives the slider 7 to move and adjust the height of the sign 5 through the threaded connection.

[0025] refer to Figure 3The rotating mechanism 9 includes a driving rod 91, a groove 92, a spring 93 and a rotating groove 94. The driving rod 91 is movably connected to the left side of the fixed frame 4.

[0026] As a technical optimization solution of the present invention, by setting a rotating mechanism 9, the sleeve 95 is pressed to slide inside the groove 92 opened by the driving rod 91, and then the sleeve 95 drives the positioning column 96 to move, and then the positioning column 96 slides in the rotating groove 94. At the same time, the sleeve 95 squeezes the spring 93, and then the positioning column 96 slides to the left side of the rotating groove 94. Then, the spring 93 releases the pressure to drive the sleeve 95 to slide out of the rotating groove 94 through the positioning column 96, and at the same time, the driving rod 91 is rotated slightly, and then the driving rod 91 drives the sign 5 to rotate, so that the display angle of the sign 5 can be adjusted.

[0032] As a technical optimization solution of the present invention, by providing a linear bearing 12 , the rotation stability of the screw 84 is increased and the friction generated by the screw 84 is reduced.

[0033] refer to Figure 1 The right side of the slider 7 is fixedly connected with a pulley 13, and the surface of the pulley 13 is slidably connected to the right side of the inner wall of the chute 6.

[0034] As a technical optimization solution of the present invention, by providing a pulley 13 , the slider 7 drives the pulley 13 to contact the inner wall of the slide groove 6 , thereby increasing the smoothness of the movement of the slider 7 .

[0035] The working principle and usage process of the present invention are as follows: when the sign 5 is placed on the road of the project, the first bevel gear 82 is driven to rotate by starting the motor 81, and then the first bevel gear 82 is driven to rotate by the meshing connection, and then the second bevel gear 83 is driven to rotate by the second bevel gear 83, so that the second bevel gear 83 drives the screw 84 to rotate, so that the screw 84 drives the slider 7 to move and adjust the height of the sign 5 through the threaded connection, and the pressing sleeve 95 slides in the groove 92 opened by the driving rod 91, and then the sleeve 95 drives the positioning post 96 to move, and then the positioning post 96 slides in the rotating groove 94, and at the same time the sleeve 95 squeezes the spring 93, and then the positioning post 96 slides to the left side of the rotating groove 94, and then the spring 93 releases the pressure to drive the sleeve 95 to slide out of the rotating groove 94 through the positioning post 96, and at the same time the driving rod 91 is rotated slightly, and then the driving rod 91 drives the sign 5 to rotate, so that the display angle of the sign 5 can be adjusted, so far, it has the advantage of rotating and lifting adjustment of the sign 5.

[0036] In summary, the road sign 5 used in road engineering projects, provided by the present invention, employs a slider 7 and a chute 6. The slider 7 drives the connecting plate 3 to move, which in turn drives the sign 5 via the fixed frame 4. This allows the slider 7 to move within the chute 6 to adjust the sign 5. This solves the problem of poor visibility of some road signs at night or in dimly lit environments, hindering their recognition. Furthermore, since the road sign device is fixed at a fixed height after installation, different drivers' perspectives can make it difficult to read the information. Therefore, it is necessary to adjust the sign's height and position to suit the perspectives of drivers of different types of vehicles.
