Novel LED traffic sign for bridge

Abstract

A novel LED traffic sign for a bridge comprises a base fixed to a bridge frame and a sign body. Plug-in grooves are formed in the base in a left-right symmetrical mode, electrifying parts are arranged on the outer sides of the plug-in grooves, electrifying metal sheets are arranged on the front sides of the electrifying parts, lock catch grooves are formed in the front side of the base in a left-right symmetrical mode, and protruding parts sliding out towards the outer sides are arranged on the rear sides of the lock catch grooves; electrifying assemblies are arranged on the rear side face of the sign body in a left-right symmetrical mode, the electrifying assemblies comprise guide blocks matched with the plug-in grooves and slide bars fixedly arranged on the rear side face of the sign body, and first clamping grooves and second clamping grooves are formed in the guide blocks; the second clamping grooves communicate with the first clamping grooves, the slide bars extend into the first clamping grooves, and slide arms are assembled in the second clamping grooves in a sliding mode; and inclined slide faces and pressing parts are arranged on the inner sides of the slide arms, and the inclined slide faces slide out of the second clamping grooves, extend into the first clamping grooves, and are connected with the pressing parts on the rear sides of the slide bars.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a novel LED traffic sign for bridges. Background technique [0002] The bridge is usually erected on the river, so there is fog on the bridge. When the fog is thick, it will affect the traffic on the bridge deck and cause accidents. Therefore, ordinary traffic signs cannot meet the needs of the bridge deck. Self-illuminating LED traffic signs need to be installed. Generally, LED traffic signs need to be installed at a high place. The traditional method uses welding to ensure stability to prevent the signs from falling. This method makes it difficult to remove and replace signs when they are damaged. Fixing with bolts and other methods may cause the bolts to loosen easily. . Contents of the invention [0003] The object of the present invention is to provide a novel LED traffic sign for bridges, which is used to overcome the above-mentioned defects in the prior art. [0004] A novel bri...
