Description

Technical Field

[0001] This invention relates to the field of road traffic technology, specifically to a road traffic information indication device. Background Technology

[0002] Traffic information signs are graphic symbols that display traffic regulations and road information. They provide a vivid, concrete, and concise expression of traffic regulations, as well as information that is difficult to describe in words. They are used to manage traffic, indicate driving directions, and ensure smooth traffic flow and driving safety. They are applicable to highways, urban roads, and all special-purpose roads, and have the nature of laws, which must be obeyed by vehicles and pedestrians.

[0003] However, the existing traffic information display devices have fixed orientations and numbers, which cannot meet the requirements of indicating straight roads, T-junctions, crossroads, and special irregular angle intersections on actual roads. The indication effect is poor. In addition, on sunny days, sunlight shines on the display device, affecting the viewing brightness for pedestrians and drivers, thus affecting the indication effect and failing to meet the requirements of current use. Therefore, we propose a road traffic information indication device. Summary of the Invention

[0036] The bottom support box 1 has multiple support bases 60 fixedly connected to its side. Each support base 60 is threaded with a support stud 61. The bottom end of the support stud 61 is fixedly connected to a support foot 62, and the top end of the support stud 61 is fixedly connected to a rotating plate 64. Multiple casters 63 are fixedly installed on the bottom surface of the bottom support box 1. The casters 63 are used to move the device. The bottom support box 1 has a storage battery 59 installed inside. The storage battery 59 is electrically connected to the photovoltaic power generation panel 31, the main display 11, the auxiliary display 22, the micro water pump 32, and the multi-stage electric push rod 28. The storage battery 59 supplies power to the main display 11, the auxiliary display 22, the micro water pump 32, and the multi-stage electric push rod 28.

The inner wall of the slide groove 15 limits the slide seat 18 and the movable seat 19, so that the slide seat 18 and the movable seat 19 can only move along the axis of the slide rod 16 and the lead screw 17. The side of the inner indicator box 20 is attached to the inner wall of the storage groove 13. The inner wall of the storage groove 13 limits the inner indicator box 20 stored in the inner cavity of the storage groove 13.

[0038] In summary, when using this road traffic information indication device, the device is first moved to the intersection where traffic information needs to be indicated using the movable wheels 63. The rotating plate 64 drives the support stud 61 to rotate, and the cooperation between the support stud 61 and the support base 60 drives the support foot 62 to move downwards. The support foot 62 and the movable wheels 63 provide stable support for the bottom support box 1. Then, the rotating disk 57 drives the first bevel gear 58 to rotate, and the cooperation between the first bevel gear 58 and the second bevel gear 56 drives the threaded rod 50 to rotate. The cooperation between the threaded rod 50 and the vertical square column 51 adjusts the height of the external threaded column 3, the external indicator box 9, the main display 11, and the auxiliary display 22, so that the main display 11 and the auxiliary display 22 display the traffic information. The information display is easily visible to pedestrians and drivers. The spring force of the first spring 53 causes the first pin 55 to insert into the first socket 52 to fix the vertical square post 51. When used on straight roads, traffic information is displayed directly through the main displays 11 inside the two outer indicator boxes 9. When used at T-junctions, rotating the rotating disk 25 on the side of one outer indicator box 9 rotates the lead screw 17, causing the inner indicator box 20 to extend from the inner cavity of the storage slot 13 via the threaded engagement between the lead screw 17 and the moving seat 19. When the inner end of the inner indicator box 20 extends to the outer rotating slot 14, the inner indicator box 20 is rotated 90 degrees, causing the outer indicator box 9 and the inner indicator box 20 to be arranged vertically. The bolt 38 at the end of the movable fixing bracket 37 is moved to a fixing screw hole 24 on the top surface of the inner indicator box 20. The bolt 38 is rotated so that its bottom thread is installed into the fixing screw hole 24, fixing the position between the outer indicator box 9 and the inner indicator box 20. This allows the main displays 11 on the two outer indicator boxes 9 and the auxiliary displays 22 on the inner indicator box 20 to indicate the three directions of the T-junction. When used at a crossroads, the inner indicator boxes 20 inside the two outer indicator boxes 9 are moved out according to the above steps, and the outer indicator boxes 9 and inner indicator boxes 20 are fixed perpendicularly to each other. The two main displays 11 and two auxiliary displays 22 indicate the four directions of the crossroads. When indicating intersections with irregular angles, the bolt 38 is moved out. After the inner indicator box 20 is pulled out from inside the outer indicator box 9, the angle between the outer indicator box 9 and the inner indicator box 20 is rotated to the same angle as the irregular angle intersection. The outer indicator box 9 and the inner indicator box 20 are fixed together by the cooperation of the fixing bracket 37, bolts 38, and fixing screw holes 24. Traffic information is indicated using the auxiliary display 22 and the main display 11. When three or four irregular angle intersections appear, the nut 40 is loosened simultaneously to release the fixing of the rotating ring seat 39. The rotating ring seat 39 is then rotated on the external threaded post 3 to adjust the angle between the two outer indicator boxes 9, ensuring that the two outer indicator boxes 9 and one inner indicator box 20, or the two outer indicator boxes 9 and two inner indicator boxes 20, respectively indicate three or four irregular angle intersections.The rotating ring seat 39 is then pressed and fixed by nut 40 after rotation. Finally, the multi-stage electric push rod 28 is activated to move the pull plate 29 outward. The pull plate 29 pulls the elastic sunshade and waterproof cloth 30 to block the outer indicator box 9 and inner indicator box 20, thus shading the main display 11 and auxiliary display 22 from the sun. Additionally, the micro water pump 32 is periodically activated to draw water from the water tank 4, which is then guided through the water pipe 33 to the nozzle 34 for spraying. The water sprayed from the nozzle 34 washes the main transparent protective plate 12 and auxiliary transparent protective plate 23 on the outside of the outer indicator box 9 and inner indicator box 20, removing dust from their surfaces and ensuring the clarity of the main display 11 and auxiliary transparent protective plate 23.
