Description

Technical Field

[0001] This utility model relates to the field of vehicle stoppers, and in particular to a portable police auxiliary vehicle stopper. Background Technology

[0002] Traffic police checkpoints are a crucial measure to combat serious traffic violations and manage key vehicles, and are an important part of their work. However, many traffic violators attempt to evade punishment by forcibly breaking through checkpoints, posing a significant safety hazard to traffic enforcement officers. To avoid serious road safety issues and endanger the lives of other road users, extreme measures to forcibly stop vehicles are strictly prohibited. The value of portable police auxiliary vehicle blocking devices lies in their ability to scientifically utilize on-site physical blocking devices to employ flexible measures that disrupt the power and steering of vehicles attempting to break through checkpoints, thereby preventing serious traffic safety problems while simultaneously cracking down on such violations.

[0003] A search revealed Chinese Patent Publication No. CN221276434U, which discloses a portable police auxiliary vehicle stopper, comprising a base plate, a fixing frame, and tire-puncturing plates. The fixing frame is located at the top center of the base plate, and the tire-puncturing plates are located on both sides of the top of the base plate, with a tire-puncturing part at the top of the tire-puncturing plates. In checkpoint deployments, traffic police officers at the release points are tasked with intercepting vehicles attempting to break through checkpoints, while ensuring safety. When not activated, the portable police auxiliary vehicle stopper acts as a "slowing cone," reducing the speed of passing vehicles and improving the safety of officers at the release point. When activated, it can damage the tires of vehicles attempting to break through checkpoints, impairing their power and steering, thus serving as an auxiliary vehicle stopper. However, existing police auxiliary vehicle stoppers often use fixed cone-shaped devices to block vehicles attempting to break through checkpoints, lacking more effective means to impair the power and steering of vehicles traveling at high speeds. Utility Model Content

[0004] The purpose of this invention is to provide a portable police auxiliary vehicle stopper in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figure 1 — Figure 6 As shown, a portable police auxiliary vehicle stopper includes a speed bump 101, a reinforcing frame 102 welded inside the speed bump 101, several sets of openings 104 on both sides of the speed bump 101, and a symmetrically arranged vehicle stopping mechanism installed inside the speed bump 101. The vehicle stopping mechanism includes several rotating plates 401, with mounting shafts 402 bolted to the rotating plates 401. Fixed seats 403 are rotatably connected to both ends of the mounting shafts 402, and the fixed seats 403 are bolted to the speed bump 101. Several mounting seats 404 are rotatably connected to the rotating plates 401. A cone nail 405 is bolted to the mounting base 404. A cutting mechanism is provided on the rotating plate 401. The cutting mechanism includes a fixed frame 504, which is bolted to the rotating plate 401. A cutting wheel 505 is rotatably connected inside the fixed frame 504. In use, the cone nail 405 and the cutting wheel 505 are located on the inclined surface of the speed bump 101, which can more effectively damage the vehicle tires. The cutting mechanism includes a linkage component. The linkage component is used to rotate the cutting wheel 505 to cut the tire when a vehicle traveling at too high speed hits the cone nail 405.

[0028] The reinforcement frame 102 is equipped with a docking mechanism and a transmission mechanism. The docking mechanism and the transmission mechanism are used to lift the rotating plate 401 so that the cone nail 405 and the cutting wheel 505 extend out of the opening 104. When the cone nail 405 and the cutting wheel 505 do not extend out of the opening 104, the speed bump 101 can play a certain role in slowing down the vehicle. When the rotating plate 401 flips up and the cone nail 405 and the cutting wheel 505 extend out of the opening 104, they can damage the vehicle tires, affect the vehicle's steering and forward power, and effectively prevent vehicles from running through the checkpoint.

[0029] In this embodiment, the linkage component includes a movable plate 501, which is slidably disposed within a rotating plate 401. A connecting steel cable 502 is provided between the movable plate 501 and the mounting base 404. A lever 503 is bolted to the movable plate 501, and a lever 506 is bolted to one end of the cutting wheel 505. The lever 503 extends from inside the rotating plate 401 and is used to actuate the lever 506 during movement, causing the cutting wheel 505 to rotate and achieve a more effective cutting effect on the tire. A spring 507 is installed between the movable plate 501 and the rotating plate 401. When the vehicle that has attempted to break through the checkpoint reaches the speed bump 101, a spring 507 is installed between them. The vehicle tire first encounters the cone nail 405, which can puncture the tire. The subsequent puncturing wheel 505 also punctures the tire when it hits the blade, thus reducing vehicle speed. When the vehicle speed is too high, the impact force on the cone nail 405 increases, causing the mounting base 404 at the bottom of the cone nail 405 to rotate. The cone nail 405 falls into the opening 104, preventing it from breaking and increasing the device's lifespan. The mounting base 404, via the connecting steel cable 502, pulls the moving plate 501, causing the spring 507 to extend. The moving plate 501 then moves the lever 503. The lever 503 moves towards the dial wheel 506, causing the dial wheel 506 to rotate. The dial wheel 506 then rotates the puncturing wheel 505, effectively puncturing the vehicle tire and further impairing the vehicle's power.

[0030] In this embodiment, the transmission mechanism includes a movable seat 301, which is slidably connected to the speed reduction belt 101. One end of the movable seat 301 is connected to a push ring 303 by bolts. A transmission rod 304 is rotatably connected inside the push ring 303. Several push rods 305 are connected to the transmission rod 304 by bolts. One end of the push rod 305 is rotatably connected to a connecting shaft 306, which is rotatably connected to the inner side of the rotating plate 401.

[0031] In this embodiment, the docking mechanism includes a rotating rod 201. A bidirectional lead screw 202 is bolted to the middle section of the rotating rod 201. Two symmetrically arranged movable rings 203 are threaded onto the bidirectional lead screw 202. Connecting rods 204 are hinged to both sides of the movable rings 203. A push sleeve 205 is bolted to the connecting rod 204. A fixed rod 302 is bolted to the movable seat 301. The push sleeve 205 is rotatably connected to the fixed rod 302.

[0032] In this embodiment, one end of the rotating rod 201 is bolted to a connector 206, and the end of the rotating rod 201 away from the connector 206 is provided with a docking groove 207. Several speed bumps 101 are connected sequentially on their sides. The connector 206 and the docking groove 207 are connected, so that the workers can rotate the rotating rod 201 corresponding to the speed bump 101 at one end, and at the same time, all the cone nails 405 and the cutting wheel 505 can extend out of the opening 104 to block vehicles running through the checkpoint on a road.

[0033] In this embodiment, the speed bump 101 has a plurality of mounting holes 103.

[0034] Working principle: Before use, several speed bumps 101 are moved to the designated checkpoint. The appropriate number of speed bumps 101 is selected based on the road width. The speed bumps 101 are installed on the ground and connected sequentially by screwing bolts into the mounting holes 103. The connector 206 aligns with the docking groove 207. When a vehicle attempts to pass through the checkpoint, the rotating rod 201 at one end is rotated, sequentially driving the bidirectional lead screws 202 within all speed bumps 101 to rotate. The bidirectional lead screws 202 drive the moving rings 203 to move. The moving rings 203 within the same speed bump 101 move closer to each other. The moving rings 203 cause the opening angle of the connecting rod 204 to decrease. The connecting rod 204 pushes out the pushing sleeve 205. The pushing sleeve 205 pushes the moving seat 301 through the fixed rod 302. The moving seat 301 then drives the transmission through the pushing ring 303. The rod 304, through the push rod 305 and the connecting shaft 306, lifts all the rotating plates 401. At the same time as the rotating plates 401 are lifted, the cone nail 405 and the cutting wheel 505 extend from the opening 104, turning the speed bump 101 into a vehicle-blocking state. When the vehicle that is trying to break through the speed bump 101 reaches the position, the vehicle tire first hits the cone nail 405, which can scratch the vehicle tire. The subsequent cutting wheel 505 can also scratch the tire when the vehicle tire runs over the blade, thereby reducing the vehicle speed. When the vehicle speed is too high, the cone nail 405 is subjected to greater impact force, and the mounting seat 404 at the bottom of the cone nail 405 rotates under force. The mounting seat 404 pulls the moving plate 501 through the connecting steel cable 502, and the spring 507 is stretched under force. The moving plate 501 drives the lever 503 to move. The lever 503 moves to the position of the dial wheel 506, thereby causing the dial wheel 506 to rotate. The dial wheel 506 drives the cutting wheel 505 to rotate, effectively cutting the vehicle tires and further damaging the vehicle's power. After use, the rotating lever 201 needs to be rotated in the opposite direction to retract the cone nail 405 and the cutting wheel 505, so that the speed bump 101 returns to the state of slowing down the vehicle.
