Description

Technical Field

[0001] The utility model relates to the field of traffic safety equipment, in particular to a buffering, pressure-resistant, protruding reflective road stud. Technical Background

[0002] Raised reflective road studs, also called raised road studs, are mainly installed on both sides of the road or on the center line of the road. The main body protrudes from the road surface, and a retro-reflector is installed on the oncoming side of the main body. It has the function of reflecting the lights of oncoming cars to provide road guidance for motor vehicle drivers.

[0003] The existing protruding reflective road studs have a shell made of plastic, and a retroreflector made of microprism retroreflectors (reflective lattice plates) or microbead array combination retroreflectors (glass beads), which are fixed in the groove of the road stud's oncoming surface by gluing or by ultrasonic hot melting. Due to the limitation of the shell material, the road stud has insufficient overall pressure resistance, and is easily broken or the retroreflector falls off or is damaged due to wheel impact, so that the road stud cannot play its reflective function.

[0004] To this end, some people use metal road spike shells to increase the overall structural strength of the road spike. However, due to the large difference in the properties of the bottom material of the retroreflector and the road spike shell material, the retroreflector and the road spike shell are not firmly bonded together, and the retroreflector is easily detached or damaged due to wheel impact and rolling, making the road spike unable to be used normally.

[0005] Some people also use a lens unit type retroreflector with a spherical lens structure on its head and a reflective coating on its lower part or bottom to meet the regression reflection conditions. The lens unit type retroreflector is implanted in the cylindrical hole of the plastic road stud shell and fixed by gluing. Although the retroreflector is not easy to fall off or be damaged due to wheel impact and rolling, it is limited by the shell material and the rolling causes the whole to break. Moreover, since no protective structure is used for the lens unit type retroreflector, the lens unit type retroreflector is easily worn by wheel impact, thereby reducing its reflective performance and even causing the lens unit type retroreflector to break.

[0006] In summary, how to provide a protruding reflective road stud whose retroreflective body is not easy to fall off and damage and has good overall compression and impact resistance has become a difficult problem to be solved urgently in the industry. Summary of the invention

[0007] In view of the shortcomings of existing products, the technical problem to be solved by the present invention is to provide a protruding reflective road stud whose retroreflective body is not easy to fall off and be damaged and has good compression and impact resistance as a whole.

The retroreflector is implanted into the cylindrical hole of the plastic road spike shell and fixed by adhesive, so that the retroreflector is not easily dropped off or damaged due to wheel impact and rolling;

[0009] In particular, an outer bottom plate is extended outwards for a certain distance at the bottom of the front (rear) side of the road spike, and a ramp body with a lower outside and a higher inside is arranged between the outer bottom plate and the side of the road spike (the part between the cylindrical holes on the side of the road spike shell for arranging the retroreflector) starting from the outer bottom plate and rising from the outside to the inside and connected to the corresponding side of the road spike. The ramp bodies can be arranged in combination with the same or different lengths, the same or different widths and the same or different heights as required, which can play a role of gentle slope transition, disperse the impact force of the tire on the side of the road spike, especially on the retroreflector, so as to withstand vehicle rolling, have less bumps, and make the retroreflector less likely to be worn or even broken due to wheel stamping, thereby ensuring the service life of the road spike, and the reflective performance of the road spike can also meet the standards.
