Description

Technical Field

[0001] The utility model relates to the field of anti-equipment non-lethal weapons, in particular to a police self-locking vehicle arrester. Background Art

[0002] Police car blockers are a type of safety equipment used in emergency situations. They are designed to stop a fugitive's vehicle to protect the public and law enforcement officers. These devices are often used on highways, city roads, and other places where fugitives need to be intercepted quickly. When the police are chasing a fugitive, they can use a police car blocker to quickly stop the vehicle and prevent the fugitive from escaping or continuing to commit crimes.

[0003] Police vehicle blockers are devices that force the vehicle being pursued to stop by certain means. In their long-term inspections and emergency response missions, researchers have found that most of the existing checkpoints and important places use passive destructive vehicle blockers, which force the car to stop by puncturing tires, locking wheels, etc. In this process, the target vehicle will inevitably cause safety hazards to surrounding vehicles and officers and soldiers.

[0004] A police mechanical car blocker is provided. The side and top cones can puncture the tires of the terrorist's vehicle and prevent the vehicle from moving forward. The car blocker can block the vehicle and further prevent the terrorist's vehicle from moving forward. The blocking effect is good and the terrorist can be quickly subdued. To this end, we propose a police self-locking car blocker to solve the above problems. Utility Model Content

[0012] Preferably, a tension spring is fixedly connected to the inner wall of the hollow block, and the other end of the tension spring is fixedly connected to the upper end of the movable rod.

[0013] The utility model provides a police self-locking car blocker through improvement, which has the following improvements and advantages compared with the prior art:

[0014] First, the utility model provides a lower connecting rod, an upper connecting rod, a slide groove, a slider, a spring, and a hollow plate. The lower connecting rod and the upper connecting rod can rotate. When the lower connecting rod is rotated to the maximum angle, the protrusion will pop out from the lower connecting rod, and then cooperate with the spring in the slide groove to make the spring pop out the slider into the slide groove. The protrusion of the slider will pop from the lower connecting rod into the slide groove in the upper connecting rod. The groove in the slide groove is used to prevent the protrusion from moving. The lower connecting rod and the upper connecting rod cannot rotate, and multiple groups of lower connecting rods and upper connecting rods cannot be retracted into the box. In this way, vehicles that forcibly break through the card can be damaged, and not only can the vehicle be intercepted, but also human damage can be avoided.

[0015] Second, the utility model provides a hollow plate, a movable block, a hollow tube, a pressure plate, a round rod, a compression spring, a hollow block, a movable rod, a limit block, a limit groove, and a trigger rod. When the hollow plate is received in the box body, the movable block will be stuck in the through groove and move backward to drive the pressure plate to move. The round rod cooperates to make the compression spring contract under pressure. After the pressure plate moves to the limit block, no pressure is applied. The pressure plate will be limited by the limit block. Then, when the lower connecting rod and the upper connecting rod need to be popped out, the trigger rods on both sides of the box body are lifted, and the movable rod will be lifted, so that the pressure plate will no longer be restricted. In this way, the movable block will be popped out, and then the hollow plate will be popped out and triggered. During the pop-up rotation process, the lower connecting rod and the upper connecting rod will pop out from the slider, and the lower connecting rod and the upper connecting rod can no longer rotate. In this way, they can be locked and can be directly popped out in an emergency to avoid manual pulling. This saves time, is more efficient, and is more convenient to intercept vehicles.
