Reflected light can the active type road traffic direction board of optically focused
Technical field
The utility model relates to a kind of public utility, and specifically a kind of reflected light can the active type road traffic direction board of optically focused.
Background technology
Road traffic direction board is indispensable equipment in public utility, and it plays indispensable effect in the process ensureing the coast is clear and traffic safety.There is following defect in traditional road traffic direction board: road traffic direction board is usually be fixed on roadside, and when running into the situations such as high wind, resistance increases, and affects for a long time by wind, loosening according to easy of direction board, and its firm performance reduces; In addition, at night, traffic indication board adopts reflective principle to indicate usually, but vehicle is irradiated to most light on direction board to be dispersed in the air, reduce the intensity of reflection ray, cause indicating effect not obvious, indicating effect is poor, and it can not be applicable to the vehicle instruction far or more nearby of distance direction board.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of reflected light can the active type road traffic direction board of optically focused.
Technical solutions of the utility model are as described below:
Reflected light can the active type road traffic direction board of optically focused, comprise column, direction board body, the index plane be located on described body, it is characterized in that, described index plane comprises transparent font index plane and nontransparent blank index plane, described index plane is located on described body, is transparent index plane fixed bed on front side of described body, and described index plane fixed bed rear is provided with reflector layer, described reflector layer is located on cushion pad, and described cushion pad rear is the back cover of described body; Leave space between described index plane fixed bed and described reflector layer, form reflection cavity, described reflector layer front is provided with guide-lighting block, forms guide-lighting groove between described guide-lighting block; Be provided with U-shaped plate above described body, the inner groovy of described U-shaped plate passes cylinder and rotates along described cylinder, and described cylinder, described U-shaped plate are located in drum shell, and described cylinder and described drum shell are fixed on described column.
Further, described guide-lighting block and described guide-lighting groove downward-sloping, and the angle of inclination of upper and lower surface is different.
Further, it is 6 °-15 ° with the angle α of horizontal direction on the upside of described guide-lighting groove.
Further, it is 25 °-60 ° with the angle β of horizontal direction on the downside of described guide-lighting groove.
Further, described body is fixedly connected with described U-shaped plate by fixed head.
Further, before and after described cylinder, both sides are respectively equipped with limited block.
According to the utility model of said structure, its beneficial effect is, under running into the situations such as high wind, the direction board in the utility model can rotate within the specific limits, the impact that the less factors such as high wind cause direction board; Reflector layer of the present utility model has obvious spotlight effect, can carry out the light reflection in a big way, decrease the diffuse reflection of light when night, and overall indicating effect is obvious, and more traditional direction board has obvious advantage.
