1. Product Features
&r;
Features:
This roadblock traffic stopper is composed of an aluminum alloy strip movable support and a hard die-cast zinc triangular edge needle. The aluminum alloy strips are connected by steel rivets to form a movable bracket that can be opened at will during use and can be simply closed after the work is completed. The triangular felting needle has a central ventilation hole and a groove on each edge thereof and is connected to the central hole. After the needle is inserted into the tire, the air in the tire will be quickly released directly from the central vent hole. It is the first choice device for intercepting cars and the nemesis of driving crimes. It is widely used in important national functional departments such as public security, armed police, and transportation. <>
2. Working principle
:
When the wheel comes into contact with the hard die-cast zinc-aluminum alloy nail roadblock, the pressure during driving causes the wheel to press against the triangular needle on the roadblock. The triangular needle will follow. Puncturing the tire in the direction the vehicle is moving and deflating the tire pressure at a speed of one kilometer per second will cause the needle to separate from the roadblock. As the wheel continues to rotate, the needle on the tire pierces deeper and deeper, and the gas in the tire leaks out from the inner hole of the needle. Generally, four to six steel nails will be pierced into the tire and all the gas will be released in less than a second. To achieve the purpose of effectively intercepting vehicles. <>
3. How to use:
<>
Open the box, take out the traffic barrier, and place it on the side of the road. The police officer holds the nylon rope connected to the traffic barrier and places it on the road. When a suspicious vehicle appeared on the other side, the rope was pulled to block the vehicle and the roadblocks were deployed. Police officers can use traffic barriers while standing in a safe position. <>
After completion, pull the nylon rope backwards to make it automatically integrate. At the same time, police officers should replace lost or damaged triangular steel pins in time for reuse, then put the roadblock into the box, wind the rope back into the winding ditch, and close the lid of the box. <>
4. Precautions:
<>
After use, the roadblocks should be inspected and corrected. The position of each triangular pin should be replaced if the damaged triangular pin is found. The missing triangular pin should be replaced. Complete to ensure effectiveness for next use.
It is necessary to protect the triangular needle from damage and pay attention to avoid injuring the operator during maintenance and use.
After use, if the roadblock is stained with dirt and other dirt, it needs to be rinsed with water and dehumidified in time; after drying, the correction triangle needle is placed in the box. <>
5. How to install the triangular pin:
<>
Unplug the damaged triangular pin. , Take out the spare triangular needle.
Align the flat end of the triangular needle with the fixed sleeve and insert it into the fixed sleeve hole. , check and calibrate the position of the triangular needle. <>
