Description

Technical Field

[0001] The utility model relates to the technical field of road equipment, and particularly relates to a road traffic signboard. Background Art

[0002] In the field of road traffic engineering, signboards are important traffic facilities for indicating road directions, traffic control, safety warnings, etc.; Patent No. CN111028665A discloses a safety traffic signboard, the surface of which may be scratched during use, resulting in blurred or damaged information and affecting road traffic safety; CN216339137U discloses a portable traffic signboard, but it cannot be carried and operated for replacement and maintenance.

[0003] Specifically, the visibility of existing signboards is insufficient at night or under low visibility conditions, which may lead to traffic accidents. The processing cost of existing signboards is relatively high, which increases the cost of traffic management. Existing signboards may be damaged by external factors such as scratches and bird droppings during use, which will affect the clarity and service life of the signboards. The replacement and maintenance process of existing signboards is relatively complex, which increases the difficulty and cost of traffic management. Therefore, there is an urgent need for a new type of road traffic signboard to solve the above problems. Summary of the Utility Model

The sign shell includes a shell skin, and a plurality of guiding grooves are provided on both sides of the shell skin, and a plurality of bottom grooves are provided at the bottom of the shell skin;

[0007] The middle of the transparent frame is hollow, the TPU film is inlaid and pasted on the inner side of the transparent frame, a reflective strip is provided on the front side of the transparent frame for being more easily seen in an environment with insufficient light, a fixing bolt is installed at the bottom of the front side of the transparent frame, and screw holes adapted to it are provided at the corresponding positions of the sign shell and the transparent frame; the transparent frame is placed in the bottom groove at the front end and fixed to the sign shell through the fixing bolt.

[0008] A plurality of the bottom grooves are sequentially provided with a sign layer, a spare layer, and a spare film. The height of the spare layer and the spare film is higher than that of the sign shell. When the road conditions ahead change, the spare layer can be pulled out and replaced with the sign layer. When the TPU film is damaged, the damaged TPU film in the transparent frame is replaced with the spare film.

[0009] On both sides of the bottom of the identification shell, there are fixed columns. The bottom surface of the columns is equipped with hinge shafts. The columns are respectively connected with three connecting rods through the hinge shafts, and a limiting chain is sequentially connected between the connecting rods.

[0010] A universal wheel is fixed at the port of the connecting rod. There is a cross plate on the side where the universal wheel is fixed to the connecting rod, and a vertical downward braking bolt is threadedly connected to the cross plate.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model designs an acrylic transparent frame embedded with a TPU (thermoplastic polyurethane) film, which has good transparency for the identification plate, ensuring visual safety; the TPU film can protect the information, text, and patterns of the identification plate from damage by external factors such as scratches and bird droppings, improving the durability of the identification plate. At the same time, the use of the transparent frame and the identification shell structure makes the TPU film not bind to the surface of the identification layer, facilitating flexible replacement; specifically, after layering, it is convenient to quickly replace the identification layer with a spare layer when the road conditions change, replace different identification information to guide pedestrian instructions, and can improve the timeliness and adaptability of road signs; at the same time, if the TPU film is damaged, the spare film can be quickly replaced to ensure the continuity of the identification.

[0013] 2. The identification plate designed by the present utility model can ensure flexible positioning and adjustment of the road position through the universal wheels, and can also keep the identification plate stable through the limiting chain, avoiding occlusion or flipping; by equipping the transparent frame with a reflective strip, its reflectivity can improve visibility under night or low visibility conditions, thereby reducing the occurrence of traffic accidents.
