Description

technical field

[0001] The invention relates to the technical field of signboards used on bridges, in particular to a stable signboard device for bridges. Background technique

[0002] Various signboards can often be seen on some bridges, which are mainly used for traffic guidance to passing vehicles or to remind or warn vehicles passing on the bridge under bad weather conditions. However, the signage needs to be powered when it is working. In the prior art, the power supply is generally through the plug-in method. The power supply method is not stable. When the wind on the bridge is strong, the signboard is easily shaken due to the large force-bearing area. As a result, the plug port is loose and the power supply connection is interrupted, causing traffic disorder and seriously affecting the normal passage of vehicles on the bridge. At the same time, the traditional signage connection method makes the power port easily exposed to the outside world. It is very prone to cond...
