Light-reflecting indicator

Abstract

The invention relates to a light-reflecting indicator. The light-reflecting indicator comprises a light reflecting plate, a lining plate, an installing plate, a supporting rod and a base, the light reflecting plate and the lining plate are buckled on the installing plate, a dust removal device is arranged on the light reflecting plate and comprises dust removal brushes, a screw propeller, magneticblocks and annular magnets, the screw propeller is arranged on the back face of the installing plate, the magnetic blocks are fixed to blades, a shaft hole is formed in the center of a hub, the pairof magnets are arranged on the two sides of the screw propeller, the dust removal brush is arranged on the front face of the light reflecting plate and fixedly installed on a rotary shaft, and the rotary shaft is inserted into the shaft hole and fixedly matched with the shaft hole. The light-reflecting indicator has the advantages that according to the dust removal device, an initial force is added to the screw proper with the help of wind force, the magnetic blocks on the blades conduct cutting magnetic induction line movement with the annular magnets, the screw propeller rotates for a long term to drive the dust removal brush to conduct constant clearing on the light reflecting plate, in this way, the working stability and continuity of the whole dust removal device are better, the cleanliness of the light reflecting plate is guaranteed, and a provided light-reflecting warning effect is durable and effective.

Description

technical field [0001] The invention belongs to the field of traffic signage, and in particular relates to an automatic dust-removing reflective signboard which works by means of wind force and magnetic force. Background technique [0002] Reflective signs are safety signs that give drivers clear driving warnings at the corners of the expressway, road bifurcations and other places. The currently used reflective signs have a single structure and do not have cleaning functions such as automatic dust removal. After a large amount of dust accumulates on the surface of the sign, it will greatly reduce the reflective effect, affect the warning function, and cause traffic safety hazards. It requires a lot of manpower to clean and wastes resources. . Contents of the invention [0003] The purpose of the present invention is to design a reflective sign with an automatic dust removal device aiming at the defects of the prior art. [0004] The solution of the present invention incl...
