Description

Technical Field

[0001] The utility model relates to the technical field of signboards, in particular to a traffic signboard. Background Art

[0002] Route traffic signs are graphic symbols that display traffic regulations and road information. They can express traffic regulations in a vivid, specific and concise manner, and at the same time express content that is difficult to describe in words. They are used to manage traffic, indicate driving directions, and ensure smooth roads and driving safety.

[0003] Publication No. CN212533802U discloses a route traffic sign for a traffic station, comprising a fixed bottom box, a mounting frame fixedly mounted at the middle position of the upper end of the fixed bottom box, a mounting cavity opened inside the fixed bottom box, a lifting motor fixedly mounted at the bottom end of the mounting cavity, a screw connected to the output shaft of the lifting motor, the upper end of the screw sequentially passes through the fixed bottom box and the mounting frame, and is rotatably connected to the top end of the mounting frame, a slider is threadedly mounted on the screw, a connecting rod is fixedly mounted on the right end of the slider, the right end of the connecting rod passes through the mounting frame and extends to the right side of the mounting frame, and is detachably fixed to the hollow fixed connecting pipe. The hollow fixed connecting tube is detachably mounted on a sign, and the front end of the hollow fixed connecting tube is fixedly connected to a mounting plate. A signal light panel is fixedly mounted on the front end of the mounting plate. Multiple water spray pipes are fixedly mounted at equal intervals on the edge of the mounting plate and connected to the sign. A rubber hose is fixedly connected to the rear end of the hollow fixed connecting tube. The bottom of the rubber hose is fixedly connected to the front end of the mounting bracket via a fixed clamp. A water pump is fixedly mounted on the rubber hose and fixedly connected to the rear end of the left side of the sign. Four mounting bolts are mounted on the fixed base box, and the four mounting bolts are distributed in a rectangular array on the fixed base box. While this type of traffic sign is easy to install and remove and has high structural strength, it is often covered with rain and snow during snowfall, which affects the visibility of the information on the sign. Due to the accumulation of snow and rain on the sign, drivers and pedestrians have difficulty in seeing the traffic information on the sign in a timely and clear manner, and thus cannot correctly obtain important instructions such as driving directions, speed limits, and parking. This information dissemination barrier not only leads to traffic chaos and increases the risk of road accidents, but also makes it impossible to provide necessary guidance in an emergency, affecting the overall smoothness and safety of traffic. Therefore, improvements are needed. Utility Model Content

[0031] Working principle: When encountering snowy weather, in order to prevent excessive rain and snow from adhering to the sign body 4 and affecting its use, it is only necessary to turn on the electric push rod 12. The electric push rod 12 can then push the rack 7 upward to move. The rack 7 slides through the slide rod 6 and the side groove 5. During the upward movement of the rack 7, it can drive the transmission gear 8 meshing with it to rotate clockwise. The transmission gear 8 can then drive the rotating gear 10 meshing with it to rotate counterclockwise. The rotating gear 10 then drives the rotating rod 9 to rotate counterclockwise. The rotating rod 9 can then drive the shielding plate 11 to rotate counterclockwise until the shielding plate 11 rotates. The shielding plate 11 can be rotated 90 degrees, and the shielding plate 11 can be located on the top of the sign body 4, thereby shielding rain and snow, and preventing rain and snow from adhering to the surface of the sign body 4 and affecting the use. The utility model uses the design of the shielding plate 11 to rotate to the top of the sign in snowy or rainy weather, effectively preventing rain and snow from directly adhering to the surface of the sign, ensuring that the sign information is clearly visible. At the same time, the electric push rod 12 and the rack 7 transmission mechanism are used to realize the automatic expansion and folding of the shielding plate 11, without manual intervention, simple operation, and improved convenience and automation of use. Rain and snow adhere to the surface of the sign, reducing the risk of moisture, ice and corrosion on the surface of the sign, thereby extending the service life of the sign. In the process of unfolding the shielding plate 11, the scraper 17 can synchronously adhere to the surface of the rubbing sign body 4, so that the snow on the surface of the sign body 4 can be scraped off. At the same time, due to the tension of the tension spring 16, the tension spring 16 can pull the round block 15 to move, and the round block 15 can drive the long rod 14 to move. At this time, the long rod 14 can drive the scraper 17 to be closer to the surface of the sign body 4, so that the snow scraping effect can be improved. In the utility model, During the unfolding process of the shielding plate 11, the scraper 17 can synchronously adhere to and rub the surface of the sign body 4, effectively and automatically clearing the snow on the surface of the sign, ensuring that the sign information is clearly visible without the need for manual cleaning. At the same time, through the tension of the tension spring 16, the round block 15 and the long rod 14 are pulled to move, so that the scraper 17 is more closely attached to the surface of the sign body 4, thereby improving the snow scraping effect and ensuring that the snow will not remain on the surface of the sign. By effectively clearing the snow on the surface of the sign, the icing and corrosion that may be caused by snow accumulation are reduced, thereby extending the service life of the sign and related mechanical devices.
