【Product Introduction】
This anti-riot product has many characteristics such as pre-assembly, recycling, free expansion and contraction, safe and effective, large road coverage, strong adaptability, lightweight, portable, easy to use, etc. Schools, enterprises and institutions, and other important departments are the preferred roadblock equipment and anti-riot equipment for intercepting illegal violent vehicles.
Taking the usual 8m roadblock as an example, a triangular thorn with 158 hard die-casting zinc alloy nails and an orange fixing sleeve show an eye-catching and insurmountable warning line at a long distance, which can be used in emergency situations. It is the first choice for forcibly controlling the movement of vehicles on the road, and it is the nemesis of violent driving crimes.
【working principle】
This road blocker is composed of an aluminum alloy strip movable support and a hard die-cast zinc triangular thorn needle. The aluminum alloy strip is connected by steel rivets into a movable bracket, which can be opened at will during use and can be simply closed after the work is completed. The triangular needle has a central vent hole, and each edge has a relinquishment groove, which is connected to the central hole. Once the needle penetrates the tire, the air in the tire is quickly released directly from the center vent.
When the wheel comes into contact with the hard die-casting zinc-aluminum alloy nail barricade, due to the pressure during driving, the wheel is pressed against the triangular thorn on the barricade. Exhaust at the rate of on/sec, pneumatic tires will separate the needle from the barricade. The wheel continues to rotate so that the puncture needle on the tire pierces deeper and deeper, and the gas in the tire leaks from the inner hole of the puncture needle. Generally, there will be four to six steel nails pierced into the tire, and all the gas will be released in less than 20 seconds. achieve the purpose of effectively intercepting vehicles.
