Warning device

Abstract

The invention relates to a warning device, which is characterized in that the body is made of transparent reinforced base material with thickness and single-piece type, the top part has at least two incidence unit swelling upward, which show a tapered incidence arch-shaped from bottom to top at the surroundings, the bottom of the body has at least two reflection unit swelling downward, which show a tapered reflection arch-shaped from top to bottom at the surroundings, the external periphery of the reflection arch-shaped has the reflective layer which can make the optical line reflex, the height of the incidence unit is no more than 10mm, the car lamp line can obtain well reflective caution impact when the incidence unit is arranged at road guide line position or two sides of the road, and make sure the travel driving safety when the vehicle running over for giving prominence to the lower height of the pavement.

Description

technical field [0001] The invention relates to the technical field of warning devices for roads, in particular to a structure with a low protruding road surface height during installation, good reflection warning effect and long service life. Background technique [0002] Road markings provide vehicle drivers with a clear view of the route and direction of travel, maintain the correct distance between vehicles, and maintain driving safety. Ideally, it must be able to provide in any environment, such as cloudy, rainy, and night Appropriate visual effects. like figure 1 Shown is a cross-sectional view of the current road marking. The main component of the current road marking 91 is thermal-plastic. In order to have a proper reflective warning effect, tiny glass with a radius of 0.1-0.4mm is added to the thermal-plastic Beads 92 (glass beads), because these a large number of tiny glass beads can reflect the light of vehicle headlights in poor light conditions, so that driver...

AI Technical Summary

Problems solved by technology

However, through field tests, these markings protruding 3mm from the road surface are easy to be ground by the continuous rolling of the vehicle due to their insufficient strength, and the attached glass beads are also easy to fall off, so that this kind of marking line can be repaired in a short time. Inner loss of reflective effect

At present, the latest technology is to sinter dozens of very small beads into a larger bead. These larger beads are combined on the marking line of hot mix resin. Large beads can still reflect the light of the vehicle and produce a warning effect, which is a major breakthrough in current technology, but the combination of such large beads and hot mix resin is still not good, and it is easy to fall off after the vehicle is rolled for a long time
