Description

Technical Field

[0001] This utility model belongs to the technical field of road traffic enforcement facilities, specifically relating to a slotted, venting, magnetically attached portable explosive cone police vehicle stopper. Background Technology

[0002] In road traffic management, when lawbreakers or perpetrators flee in vehicles, the high speed and impact force of these vehicles make interception difficult while ensuring the safety of law enforcement officers, especially on busy urban roads. A slight miscalculation during interception can easily lead to serious traffic and safety accidents. Furthermore, some drivers with weak safety awareness often drive under the influence of alcohol. When these drivers are apprehended, they may resort to extreme actions like speeding through checkpoints to evade punishment. If such vehicles are not stopped in time, they too can cause traffic and safety accidents.

[0003] To address this, tire deflation devices have been designed to cause tires of unauthorized vehicles to burst, rendering the vehicles immobile without causing damage or personal injury. However, currently used tire deflation devices typically have exposed steel spikes, making them inconvenient to store. Furthermore, the exposed spikes are not easily concealed, potentially allowing people to spot them early and take alternative routes.

[0004] To prevent intercepted vehicles from escaping, avoid collisions, and ensure the safety of officers on duty, officers often use tire deflation devices and other vehicle-stopping tools. Existing tire deflation devices fall into two categories: one is pre-laid on the road, activated remotely when a target vehicle appears, puncturing the tire and forcing it to stop; the other is not pre-laid but quickly deployed remotely when a target vehicle appears. Neither method is suitable for vehicles stopped on the roadside because their locations are not fixed, and many other vehicles pass nearby. These two types of tire deflation devices are inconvenient to deploy and remove, cannot prevent accidental injury to other vehicles and pedestrians, and are relatively large, making them cumbersome to carry and use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slotted, venting, magnetically attached portable puncture cone for police vehicles.

Reinforcing rings, limiters, and reinforcing cones strengthen the puncture cones, enhancing their strength and enabling them to puncture tires of various models. A wear-resistant carbon fiber alloy composite coating on the surface of the puncture cones improves their wear resistance, corrosion resistance, and service life. Embedded magnets and connecting rods create a secure connection between the puncture cones, forming a deceleration barrier and effectively enhancing the buffering and deceleration effect. Embedded magnetic poles within the puncture cones enable a rodless magnetic connection.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0023] like Figure 1 , 2As shown, a slotted, venting, magnetically attached portable explosive cone for police vehicles includes an elongated triangular rod 1. Inside the elongated triangular rod 1 is a triangular nail tire puncturer 2. The triangular nail tire puncturer 2 includes tire-puncturing triangular nails 3 and a triangular nail connecting rod 4 that connects the tire-puncturing triangular nails 3. The elongated triangular rod 1 is a prismatic cylindrical structure with an equilateral triangular cross-section, generally made of conventional materials such as paper, plastic-containing materials, or PP. The triangular nail tire puncturer 2 connects several tire-puncturing triangular nails 3 through the triangular nail connecting rod 4, ensuring all tire-puncturing triangular nails 3 stand upright. The triangular nail tire puncturer 2 is directly installed inside the elongated triangular rod 1. When a vehicle drives over it, the tire-puncturing triangular nails 3 extend from the elongated triangular rod 1 under pressure to puncture the tire.

[0024] like Figure 3 , 4 As shown, a slotted, venting, magnetically attached portable tire-exploding cone police vehicle stopper is described. An elongated triangular bar 1 has a tire-exploding device storage cavity 5 running through its interior, and a tire-exploding device friction strip 20 and a tire-exploding device reflective strip 21 connected to its outer surface. A triangular nail tire-exploding device 2 is installed in the tire-exploding device storage cavity 5. The tire-exploding device friction strip 20 and reflective strip 21 are provided on the elongated triangular bar 1 to improve its friction performance and provide a good buffering effect, and also to make it highly visible, preventing drivers from failing to see the tire-exploding device and speeding past, which could cause a sudden tire rupture and vehicle rollover.

[0025] like Figure 5 , 6 As shown, a slotted, venting, magnetically attached portable explosive cone for police vehicles includes a tire-puncture triangular nail 3 comprising three triangular conical tips 6. Two rhomboid reinforcing cones 14 are integrally formed on both sides of the conical tips 6. A triangular venting groove 7 is formed through the conical tips 6 and the rhomboid reinforcing cones 14. A triangular nail connecting hole 8 is formed in the middle of the tire-puncture triangular nail 3, and a strong magnetic connecting sleeve 10 is embedded inside. A welding connecting hole 11 is formed on the inner wall of the triangular nail connecting hole 8, and the tire-puncture triangular nail 3 is welded to the triangular nail connecting rod 4 through the welding connecting hole 11. The conical tips 6 and the rhomboid reinforcing cones 14 are integrated on both sides of the conical tips 6. The reinforcing cone 14 is inserted into the angular venting groove 7 of the car tire to vent the tire, which allows the tire to vent slowly and reduces the car's inertia. The puncture triangular nail 3 is installed and connected to the triangular nail connecting rod 4 through the welding connection hole 11 on the inner wall of the triangular nail connecting hole 8, or the strong magnetic connecting sleeve 10 embedded in the puncture triangular nail 3 is used to achieve magnetic connection between the puncture triangular nails 3. This is because the strong magnetic connecting sleeve 10 in the puncture triangular nail 3 will form magnetic poles on both sides of the puncture triangular nail 3, making the puncture triangular nail 3 a magnetic pole and achieving magnetic pole attraction between opposite poles.

[0026] like Figure 5 , 6As shown, a slotted, venting, magnetically attached portable explosive cone for police vehicles is disclosed. The conical tip 6 of the tire-puncture triangular nail 3 is integrally connected to the tire-puncture triangular nail 3, with a thickness of 4-6 mm. The tip of the conical tip 6 is a rhomboid pyramid. A rhomboid reinforcing cone 14 is integrally connected to the conical tip 6, with the tip of the rhomboid reinforcing cone 14 fused to the conical tip 6. A rhomboid limiting cone 13 is integrally provided on the outer side of the rhomboid reinforcing cone 14, and a triangular nail reinforcing ring 12 is integrally provided on the outer side of the rhomboid limiting cone 13. The end of the rhomboid limiting cone 13 near the triangular nail reinforcing ring 12 is at the same height as the triangular nail reinforcing ring 12, and the height of the end near the triangular venting through groove 7 is half the thickness of the triangular nail reinforcing ring 12. The upper part is provided with a limiting cone ridge tip; the diamond limiting cone 13 on the surface of the diamond reinforcing cone 14 is lower near the cone tip 6 or near the triangular venting groove 7, and higher near the triangular nail reinforcing ring 12, which effectively limits the cone tip 6 and the diamond reinforcing cone 14 after they pierce the tire, and prevents the entire puncture triangular nail 3 from completely piercing the tire, so that the triangular venting groove 7 cannot effectively vent air. The triangular nail reinforcing ring 12 and the diamond limiting cone 13 further reinforce the cone tip 6 and the diamond reinforcing cone 14.

[0027] like Figure 5 , 6 As shown, a slotted, venting, magnetically attached portable explosive cone for police vehicles is disclosed. The thickness of the rhomboid reinforcing cone 14 is 2-3 mm, the thickness of the triangular nail reinforcing ring 12 is 2-3 mm, and the height of the triangular nail reinforcing ring 12 is 2-3 mm. A porous support reinforcing block 9 is filled inside the triangular venting groove 7. The porous support reinforcing block 9 is embedded in the triangular venting groove 7 and is the same height, width, and length as the triangular venting groove 7. The venting operation is achieved by the conical tip 6 and the rhomboid reinforcing cone 14 after they pierce the tire through the triangular venting groove 7. The porous support reinforcing block 9 is filled inside the triangular venting groove 7 to reinforce the area where the conical tip 6 and the rhomboid reinforcing cone 14 are vented through the triangular venting groove 7, thus preventing the conical tip 6 and the rhomboid reinforcing cone 14 from breaking out of the triangular venting groove 7 due to the squeezing force.

[0028] like Figure 7As shown, a slotted, venting, magnetically attached portable explosive cone for police vehicles is described. The two ends of the triangular nail connecting rod 4 are configured as welding ends 16. Strong magnetic connecting blocks 17 are filled inside the welding ends 16. The front end of the welding ends 16 is configured as an end welding strip 18, with welding heads 19 on the end welding strip 18. The triangular nail connecting rod 4 is directly welded to the welding connection hole 11 on the tire-puncturing triangular nail 3 via the welding heads 19 on the end welding strip 18. The strong magnetic connecting block 17 inside the welding end 16 is magnetically connected to the strong magnetic connecting sleeve 10 inside the tire-puncture triangular nail 3. The strong magnetic connection between the strong magnetic connecting sleeve 10 and the strong magnetic connecting block 17 inside the welding end 16 can realize the magnetic connection between the tire-puncture triangular nail 3 and the triangular nail connecting rod 4. The tire-puncture triangular nail 3 and the triangular nail connecting rod 4 are further fixedly connected by directly welding the welding head 19 on the welding strip 18 to the welding connection hole 11 on the tire-puncture triangular nail 3.

[0029] Furthermore, the lengths of the elongated triangular rod 1 and the triangular nail tire puncture device 2 are set to 300-3000 mm, and 4-50 tire puncture triangular nails 3 are equidistantly installed on the triangular nail connecting rod 4 of the triangular nail tire puncture device 2; the straight-line distance between the conical tips 6 of the tire puncture triangular nails 3 is 10-100 mm, and the length of the triangular venting through groove 7 is 30-45 mm and the width is 2-5 mm.

[0030] Furthermore, a deceleration bar 15 is provided between the connecting welded ends 16 of the triangular nail connecting rod 4. The deceleration bar 15 is welded to the tire-puncture triangular nail 3 through the integrated connecting welded ends 16. The deceleration bar 15 is configured to connect to a chain, a soft steel bar, a strong rope, or a spring. The deceleration bar 15 and the tire-puncture triangular nail 3 form a deceleration barrier. By connecting the tire-puncture triangular nail 3 that has been punctured into the tire and the tire-puncture triangular nail 3 that has not been punctured into the tire through the deceleration bar 15, a deceleration barrier is formed to achieve rapid deceleration of the tire.

[0031] Furthermore, the outer surfaces of the conical tip 6, the triangular nail reinforcing ring 12, the rhomboid limiting cone 13, and the rhomboid reinforcing cone 14 are all coated with a wear-resistant carbon fiber alloy composite material film, with the thickness of the wear-resistant carbon fiber alloy composite material film set to 1-2 mm. By covering the outer surfaces of the conical tip 6, the triangular nail reinforcing ring 12, the rhomboid limiting cone 13, and the rhomboid reinforcing cone 14 with a wear-resistant carbon fiber alloy composite material film, the wear resistance, corrosion resistance, and service life of the tire-puncture triangular nail 3 are effectively improved.

[0032] The working principle is as follows: During transport, place the triangular nail tire puncture device 2 directly into the tire puncture device storage cavity 5 of the elongated triangular bar 1 to prevent the triangular nail tire puncture device 2 from shaking and injuring the operator. When in use, simply place the elongated triangular bar 1 together with the triangular nail tire puncture device 2 on the road where tire punctures need to be prevented. The elongated triangular bar 1 is equipped with a tire stop friction strip 20 and a tire stop reflective strip 21. The tire stop friction strip 20 improves the friction performance of the elongated triangular bar 1 and can play a good buffering role. The tire stop reflective strip 21 plays a conspicuous role, preventing drivers from rushing over without seeing the tire puncture device, which could cause the tire to burst instantly and the car to overturn. When a car drives over the tire deflation device, the outer tire of the car comes into contact with the long triangular bar 1, generating a squeezing force that acts on the long triangular bar 1, and then on the triangular nail tire deflation device 2. Because the conical tip 6 of the deflation triangular nail 3 on the triangular nail tire deflation device 2 remains upright under the traction of the triangular nail connecting rod 4, the deflation triangular nail 3 will always have one conical tip 6 standing upright with the support of the three conical tips 6, and will not tip over when subjected to lateral pressure of 15-90°. At this time, the pressure of the conical tip 6 under the squeezing force is extremely high, causing the conical tip 6 and the rhomboid reinforcing cone 14 to directly pierce the long triangular bar 1. The car tire continues to move, and the conical tip 6 and the rhomboid reinforcing cone 14 of the deflation triangular nail 3 further puncture the outer tire and inner tire of the car tire. Because the conical tip 6 and the rhomboid reinforcing cone 14 are provided with triangular venting grooves 7, when the conical tip 6 and the rhomboid reinforcing cone 14 pierce the inner tube of the tire, the triangular venting grooves 7 will vent the tire. The gas will be released from the bottom of the triangular venting grooves 7. The porous support reinforcing block 9 can reinforce the triangular venting grooves 7 when they are subjected to tire compression, and will not block the venting process of the triangular venting grooves 7. The rhomboid limiting cone 13 ensures that the conical tip 6 and the rhomboid reinforcing cone 14 will not completely submerge the triangular venting grooves 7 after they pierce the tire. The triangular nail reinforcing ring 12 and the rhomboid limiting cone 13 reinforce the conical tip 6 and the rhomboid reinforcing cone 14. Because the strong magnetic connecting sleeve 10 is embedded in the puncture triangular nail 3, the puncture triangular nail 3 is given magnetism and magnetic poles. When the puncture triangular nail 3 is not connected by the triangular nail connecting rod 4, the puncture triangular nail 3 with magnetism and magnetic poles can be directly connected by magnetic attraction of opposite poles, and puncture work can also be performed. When the puncture triangular nail 3 is connected by the triangular nail connecting rod 4, the puncture triangular nail 3 and the triangular nail connecting rod 4 can be magnetically connected by the strong magnetic connecting sleeve 10 and the strong magnetic connecting block 17 inside the connecting welding end 16. The puncture triangular nail 3 and the triangular nail connecting rod 4 are further fixedly connected by directly welding the welding head 19 on the end welding strip 18 to the welding connection hole 11 on the puncture triangular nail 3. Because the puncture triangular nail 3 is inserted into the tire by the three conical sharp corners 6, the car will not stop instantly. The tire will move forward with the puncture triangular nail 3. At this time, all the puncture triangular nails 3 on the connecting rod 4 can play a good deceleration role. The connecting deceleration rod 15 is set to connect one of the following: chain, soft steel bar, strong rope, and spring. By connecting the connecting deceleration rod 15 to the puncture triangular nails 3 that have been inserted into the tire and the puncture triangular nails 3 that have not been inserted into the tire, a deceleration barrier is formed to achieve rapid deceleration of the tire and improve the deceleration effect. By covering the outer surfaces of the tapered tip 6, the triangular nail reinforcing ring 12, the rhomboid limiting cone 13, and the rhomboid reinforcing cone 14 with a wear-resistant carbon fiber alloy composite material coating, the wear resistance, corrosion resistance, and service life of the tire-puncture triangular nail 3 are effectively improved.
