Compared with the conventional vehicle intercepting technology, the pneumatic vehicle stopping mechanism of the present invention can restrain the traveling vehicle wheel, and the stopping mechanism will puncture the stopping mechanism with the wheel through the pneumatic nail; because of the volume and weight Larger, the pneumatic vehicle stopping mechanism does not rotate with the wheel, but can brake the wheel instantaneously. The braking wheel is pressed against the pneumatic vehicle stopping mechanism and is relatively stationary; at this time, the car will continue to drive by inertia. During driving, the pneumatic vehicle stopping mechanism rubs against the ground, and the inertially driven car is stopped by the friction between the pneumatic vehicle stopping mechanism and the ground. For the structure of the pneumatic vehicle stopping mechanism, the triggering arc plate can be moved up and down by the cooperation of the arc plate guiding block and the arc plate guiding groove and the telescopic column; the car first starts from the guiding block of the triggering arc plate to the stopping mechanism. As the car wheel is gradually pressed against the outer casing, the trigger arc plate is gradually moved downward; the design of the baffle prevents the arc plate guide block from sliding out of the arc plate guide groove, thereby preventing the triggering arc plate from sliding out of the outer casing, and the design of the telescopic column is Increasing the stability of the triggering arc on the lower and lower movements; when the triggering arc plate moves under the pressure of the wheel, the triggering arc plate drives the piston to move downward through the horizontal plate and the piston plate to compress the air in the cylinder; the piston has the gas nail The pressure plate and the gas nail pressure plate move downward with the piston. When the piston moves to the design position, the gas nail pressure plate contacts the gas nail trigger rod, and the gas nail trigger rod is pressed, and the air nail switch is made by dialing the gas nail lever. Open, at this time, the gas in the cylinder is compressed to the design pressure, and the high-pressure air flows from the cylinder through the main passage and the main inlet into the bottom end of the air nail base of the air nail column, and applies upward pressure to the air nail base; The high-pressure air of the cylinder presses the rotating groove on the base of the air nail through the main passage, the rotating passage and the rotating inlet, and the rotating groove has a certain distance from the center of the air nail base, and the generated force causes the air nail base to rotate; After the air nail base is pushed by the lower side of the air nail base, the air nail snap ring on the air nail base is off After the gas-filled shell snap ring made of rubber material moves upwards, and the force applied by the rotating inlet of the side is applied, the gas nail will rotate; the air nail that rotates upward will pierce the wheel tire because the gas nail It has a spiral pattern and is screwed into the tire by rotation. The gas nail will be difficult to be pulled out directly without reverse rotation, so the incoming gas nail will be kept in the tire; the gas nail is supported by the thrust. After the upward movement, the air nail base will be blocked by the retaining ring, preventing the gas nail from coming out of the air nail shell and losing the purpose of binding the wheel and the stopping mechanism. When the air nail binds the tire, the car will drag the pneumatic vehicle stop mechanism to slide forward together, because the bottom area of the pneumatic vehicle stop mechanism is large, the friction generated is large, and the car in motion can be quickly stopped; The purpose of the cover design is to carry the load when the car is driven to the stopping mechanism, and at the same time ensure that it does not interfere with the horizontal plate or the like.

The balance mechanism installed on the pneumatic vehicle stopping mechanism can prevent the front and back of the vehicle and the stopping mechanism from being unbalanced and causing the accident of rolling forward during the braking process of the vehicle. The specific principle is that when the piston is pressed by the wheel, the piston moves downward with the balance platen. When the balance platen touches the balance trigger lever, the balance trigger lever drives the balance lock block to move downward, and the balance lock block is moved from the previous The balance housing lock groove moves downwardly out of the balance case lock groove, and loses the locking effect on the balance case lock groove; after the lock function of the balance lock block is lost, the balance case moves along the balance bar and the balance card body under the action of the balance spring thrust Passing through the balance hole of the outer casing to the outer casing; the outer balance shell increases the front and rear length of the stopping mechanism on the one hand, and prevents the car from turning forward; on the other hand, the protruding balance shell penetrates into the connecting member. Balance the shell in the perforation. The two balance shell perforations on each connector correspond to two adjacent balance shells of adjacent pneumatic vehicle stop mechanisms; such a design is intended for a stop belt composed of a plurality of pneumatic vehicle stop mechanisms, The wheel of the car that needs to be stopped may be pressed against any of the stopping mechanisms, or one of the wheels spans two stopping mechanisms. At this time, when the wheel is pressed to a stopping mechanism, the two balancing mechanisms of the same stopping mechanism The shell protrudes into the perforations adjacent to the two balance shells, causing the two connecting members to slide together, and does not affect the stopping mechanism that is not pressed by the wheel; when the wheel crosses the two stopping mechanisms The two adjacent stopping mechanisms are on the one hand bound by the tires to the adjacent two air nails on the two stopping mechanisms, and on the other hand by the connecting pieces pierced by the balancing shell to the two stopping mechanisms The restraining effect of the adjacent balance shells, the two restraining effects enable the two adjacent stopping mechanisms to be integrated to function as a stop for the car. The invention uses the pneumatic vehicle stopping mechanism to restrain the wheel, quickly brakes the car without destroying the automobile, and assists the public security organ to achieve the purpose of stopping the illegal vehicle, and has a good use effect.

When the air nails bind the tires, the car will drag the pneumatic vehicle stop mechanism to slide forward together, because the bottom area of the pneumatic vehicle stop mechanism is large, and the friction is large, which can quickly stop the moving car.

The balance mechanism installed on the pneumatic vehicle stopping mechanism can prevent the front and back of the vehicle and the stopping mechanism from being unbalanced and causing the accident of rolling forward during the braking process of the vehicle. The specific principle is that when the piston is pressed by the wheel, the piston moves downward with the balance platen. When the balance platen touches the balance trigger lever, the balance trigger lever drives the balance lock block to move downward, and the balance lock block is moved from the previous The balance case lock groove moves downwardly out of the balance case lock groove, and loses the locking effect on the balance case lock groove; after the lock of the balance lock block is lost, the balance case passes through the balance bar along the balance bar under the action of the balance spring thrust The balance hole is pierced out to the outer casing; the balance shell that is worn out increases the front and rear lengths of the stopping mechanism on the one hand, and prevents the car from turning forward; The extended balance shell penetrates into the balance shell perforations in the connector. As shown in Figure 14, the two balance shell perforations on each connector correspond to two adjacent balance shells of adjacent pneumatic vehicle stop mechanisms; such a design is intended for a plurality of pneumatic vehicle stop mechanisms The stopping belt, the wheel of the car that needs to be stopped may be pressed against any stopping mechanism, or one wheel spans two stopping mechanisms.
