Description

Technical Field

[0001] This utility model belongs to the technical field of road traffic enforcement facilities, specifically relating to a portable explosive cone police vehicle stopper with prism-shaped gas release. 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 portable, prismatic tire-puncturing cone police vehicle stopper. The vehicle stopper employs a three-conical-pointed puncture cone structure, significantly improving its stability. By incorporating reinforcing prisms and puncture conduits at the conical points, the puncture cone allows for smooth and rapid deflation of the tire, prompting the vehicle to stop quickly and effectively. The conical points are reinforced with reinforcing prisms, reinforcing rings, and modified ultra-high molecular weight polyethylene carbon fiber, increasing their strength and enabling them to puncture tires of various models. A connecting rod links several puncture cones, creating a chain reaction that cushions the impact and stops the vehicle. The overall structure of the vehicle stopper is lightweight, easy to carry, and convenient to deploy. It punctures the tire, releasing air within seconds, and simultaneously entangles the wheel, forcing the vehicle to slow down and stop.

[0006] To achieve the objective of this utility model, the technical solution adopted is as follows: A portable explosive cone for police vehicles with prism-shaped venting mechanism includes an elongated triangular bar, inside which a triangular nail tire puncturer is installed. The triangular nail tire puncturer includes a tire-puncturing triangular nail and a triangular nail connecting rod that passes through and connects to the tire-puncturing triangular nail.

[0007] As a preferred embodiment, the tire puncture triangular nail includes three conical tips forming a triangle, with a triangular nail reinforcing prism integrally provided on both sides of the conical tips, and a prism venting conduit running through the interior of the triangular nail reinforcing prism.

The two hypotenuses of the elongated triangular bar rotate around the connecting hinge at the connection with the base and are magnetically connected by the strong permanent magnet.

[0010] Preferably, the length of the elongated triangular bar and the triangular nail tire puncture device is set to 300-3000 mm, and 4-50 tire puncture triangular nails are equidistantly installed on the triangular nail connecting rod of the triangular nail tire puncture device.

[0011] Preferably, the straight-line distance between the conical tips of the tire-puncture triangular nail is 50-90 mm, and the length of the reinforcing prism of the triangular nail is 30-45 mm and the width is 2-5 mm.

[0012] Preferably, the tapered tip of the tire puncture triangular nail is integrated with the tire puncture triangular nail and has a thickness of 4-6 mm. The tip of the tapered tip is a rhomboid pyramid tip. The reinforcing prism of the triangular nail is integrated with the tapered tip and the tip of the reinforcing prism of the triangular nail is fused with the tapered tip.

[0013] As a preferred embodiment, the tail of the triangular nail reinforced prism (9) is integrally connected with a triangular nail reinforcing ring (12), and the triangular nail reinforcing ring (12) is provided with several reinforcing ring air guide holes (11). Each tire-puncturing triangular nail (3) is directly fixedly connected to the triangular nail connecting rod (4) through the triangular nail reinforcing ring (12).

[0014] Preferably, the triangular nail connecting rod (4) is provided with multiple segments, and each segment has a connecting welding end at both ends. The connecting welding end is inserted into the triangular nail reinforcing ring (12) of the tire-damaging triangular nail (3) and directly welded to the tire-damaging triangular nail (3).

[0015] Preferably, there is a connecting deceleration bar between the connecting and welding ends of the triangular nail connecting rod (4). The connecting deceleration bar is welded to the tire-puncture triangular nail (3) through an integrated connecting and welding end.

[0016] Preferably, the outer surface of the conical tip of the tire-puncture triangular nail is wrapped with ceramic-modified ultra-high molecular weight polyethylene carbon fiber, and the coverage length of the ceramic-modified ultra-high molecular weight polyethylene carbon fiber at the conical tip is the same as the prism length of the triangular nail reinforcing prism.

[0017] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a prism-shaped, portable explosive cone police vehicle stopper, the beneficial effects of which are: The tire puncture device employs a three-conical-pointed triangular nail structure, significantly enhancing its stability.

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

[0022] like Figure 1 , 2 As shown, a portable prism-shaped tire-bursting cone for police vehicles includes an elongated triangular rod 1. Inside the elongated triangular rod 1 is a triangular nail tire-bursting device 2. The triangular nail tire-bursting device 2 includes tire-bursting triangular nails 3 and a triangular nail connecting rod 4 that connects the tire-bursting triangular nails 3. The elongated triangular rod 1 is a prism-shaped 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-bursting device 2 connects several tire-bursting triangular nails 3 through the triangular nail connecting rod 4, ensuring that all the tire-bursting triangular nails 3 stand upright. The triangular nail tire-bursting device 2 is directly installed inside the elongated triangular rod 1. When a vehicle drives over it, the tire-bursting triangular nails 3 extend from the elongated triangular rod 1 under pressure to puncture the tire.

[0023] like Figure 1 , 2 As shown in Figure 3, a portable prism-shaped tire-exploding cone for police vehicles includes a long triangular rod 1 with a tire-exploding device storage cavity 5 inside, in which a triangular nail tire-exploding device 2 is installed. A connecting hinge 6 is installed at the connection between the two inclined sides and the base of the long triangular rod 1, and a strong permanent magnet 7 is installed at the connection between the two inclined sides. The two inclined sides of the long triangular rod 1 rotate around the connecting hinge 6 at the connection with the base and are magnetically connected by the strong permanent magnet 7. The connecting hinge 6 allows the two inclined sides of the long triangular rod 1 to be separated from the strong permanent magnet 7 directly through the tire-exploding triangular nail 3 when subjected to tire pressure, thus preventing the tire-exploding triangular nail 3 from piercing the long triangular rod 1 and ensuring its integrity. When the long triangular rod 1 is forcefully separated by the strong permanent magnet 7 and naturally flattens on the ground, the tire-exploding triangular nail 3 provides support between itself and the tire.

[0024] like Figure 4 As shown, a portable prism-shaped explosive cone for police vehicles is disclosed. The puncture triangular nail 3 includes three triangular conical tips 8. A triangular nail reinforcing prism 9 is integrally formed on both sides of each conical tip 8. A prism-shaped explosive conduit 10 is internally installed within the reinforcing prism 9. A triangular nail reinforcing ring 12 is integrally connected to the tail of the reinforcing prism 9. The reinforcing ring 12 has several reinforcing ring vent holes 11. Each puncture triangular nail 3 is connected to the three conical tips 8 via the reinforcing ring 12. The corner nail connecting rod 4 is directly fixedly connected. The three pyramidal pointed corners 8 on the puncture triangular nail 3 have very sharp tips. When subjected to pressure, they directly open the long triangular bar 1 to puncture the tire. The triangular nail reinforcing prism 9 on the pointed corner 8 reinforces the pointed corner 8 and prevents the pointed corner 8 from bending under the pressure of the car. The prism venting conduit 10 on the triangular nail reinforcing prism 9 directly vents the tire after the device punctures the tire, which can make the tire vent slowly and reduce the inertia of the car.

[0025] like Figure 5 As shown, a portable prism-shaped tire deflation cone police vehicle stopper is provided with a tire stopper friction strip 13 and a tire stopper reflective strip 14 connected to the outer surface of the elongated triangular bar 1. The tire stopper friction strip 13 and tire stopper reflective strip 14 are provided on the elongated triangular bar 1 to improve the friction performance of the elongated triangular bar 1 and provide a good buffering effect. Secondly, they serve to make the vehicle more conspicuous, preventing drivers from rushing over the tire stopper without seeing it, which could cause the tire to burst instantly and the car to overturn.

[0026] Furthermore, the lengths of the elongated triangular rod 1 and the triangular nail tire puncture device 2 are set to 300-3000 mm. 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 8 of the tire puncture triangular nails 3 is 50-90 mm. The length of the triangular nail reinforcing prism 9 is 30-45 mm and the width is 2-5 mm. The tail end of the conical tip 8 of the tire puncture triangular nail 3 is integrally connected with the tire puncture triangular nail 3 and the thickness is set to 4-6 mm. The tip of the conical tip 8 is set as a rhomboid pyramid tip. The triangular nail reinforcing prism 9 is integrally connected with the conical tip 8, and the tip of the triangular nail reinforcing prism 9 is fused with the conical tip 8.

[0027] Furthermore, the triangular nail connecting rod 4 is provided with multiple segments, each segment having connecting and welding ends at both ends. The connecting and welding ends are inserted into the triangular nail reinforcing ring 12 of the tire-puncture triangular nail 3 and directly welded to the tire-puncture triangular nail 3. There is a connecting deceleration rod between the connecting and welding ends of the triangular nail connecting rod 4. The connecting deceleration rod is welded to the tire-puncture triangular nail 3 through an integrated connecting and welding end. The connecting deceleration rod is configured as one of connecting chain, connecting soft steel bar, connecting strong rope, and connecting spring, forming a deceleration barrier with the tire-puncture triangular nail 3. The connecting deceleration rod connects 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, forming a deceleration barrier to achieve rapid tire deceleration. The outer surface of the conical tip 8 of the tire-puncture triangular nail 3 is wrapped with ceramic-based modified ultra-high molecular weight polyethylene carbon fiber. The coverage length of the ceramic-based modified ultra-high molecular weight polyethylene carbon fiber on the conical tip 8 is the same as the prism length of the triangular nail reinforcing prism 9. The outer surface of the conical tip 8 can be wrapped with ceramic-based modified ultra-high molecular weight polyethylene carbon fiber, which can improve its strength and stiffness.

[0028] The working principle is as follows: During transport, the triangular nail tire breaker 2 is placed directly in the tire breaker storage cavity 5 of the elongated triangular rod 1 to prevent the triangular nail tire breaker 2 from shaking and injuring the operator. The two inclined sides of the elongated triangular rod 1 can be rotated by the connecting hinge 6 at the connection between the two inclined sides and the bottom side. The two inclined sides are then magnetically connected by the strong permanent magnet strip 7 at the top of the two inclined sides to form a complete elongated triangular rod 1. Ordinary small squeezing force will not separate the strong permanent magnet strip 7 at the top of the two inclined sides of the elongated triangular rod 1, ensuring the safety of using the elongated triangular rod 1. When in use, simply place the elongated triangular bar 1 along 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 puncture friction strip 13 and a tire puncture reflective strip 14. The tire puncture friction strip 13 improves the friction performance of the elongated triangular bar 1 and can play a good buffering role. The tire puncture reflective strip 14 plays a conspicuous role, preventing drivers from rushing over without seeing the tire puncture device, which could cause the tire to puncture instantly and the car to overturn. When a car drives over the tire puncture 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 puncture device 2. Because the conical tip 8 of the puncture triangular nail 3 on the triangular nail tire puncture device 2 remains upright under the traction of the triangular nail connecting rod 4, the puncture triangular nail 3 will always have one conical tip 8 standing upright with the support of the three conical tips 8, and will not tip over when subjected to lateral pressure of 15-90°. At this time, the pressure of the conical tip 8 under the squeezing force is extremely high, causing the conical tip 8 to directly separate the strong permanent magnetic strip 7 at the top of the two inclined sides of the long triangular bar 1 from the connection point of the top of the two inclined sides. At this time, the two inclined sides of the long triangular bar 1 will fall down and flatten on the ground, and the conical tip 8 of the puncture triangular nail 3 will then puncture the outer tire and inner tire of the car tire. Because the conical tip 8 is provided with a triangular nail reinforcing prism 9, the tips of the conical tip 8 and the triangular nail reinforcing prism 9 converge to form a puncture tip. The triangular nail reinforcing prism 9 can reinforce the conical tip 8. When the triangular nail reinforcing prism 9 punctures the inner tube of the tire, the prism venting duct 10 on the triangular nail reinforcing prism 9 will release air from the tire. The gas enters the reinforcing ring vent 11 on the triangular nail reinforcing ring 12 from the prism venting duct 10 on the triangular nail reinforcing prism 9, and then releases all the gas from the reinforcing ring vent 11. The triangular nail reinforcing ring 12 also reinforces the conical tip 8. Because the puncture triangular nail 3 is inserted into the tire by the three conical sharp corners 8, 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 triangular nail connecting rod 4 can play a good deceleration role. The triangular nail connecting rod 4 can be connected to a chain, a soft steel bar, a strong rope, or a spring to form a deceleration barrier to achieve rapid deceleration of the tire and greatly improve the deceleration effect. Example 2

[0029] The difference between this embodiment and Embodiment 1 is that: like Figure 1 , 2 As shown in Figure 3, a portable prism-shaped deflation cone for police vehicles is described. The tire deflation cone 3 includes three triangular cone-shaped sharp corners 8. A prism-shaped deflation groove is integrally provided on the cone-shaped sharp corners 8. The prism-shaped deflation groove allows the tire to deflate after the cone-shaped sharp corners 8 are inserted into the tire. Furthermore, several deflation holes can be provided on the side convex wall of the prism-shaped deflation groove to achieve rapid tire deflation.

[0030] In this invention, the tire puncture device employs a three-conical-angled triangular nail structure, significantly enhancing its stability. By incorporating reinforcing prisms and venting conduits at the conical angles, the device achieves smooth and rapid deflation of the tire, prompting the vehicle to stop quickly and effectively. The conical angles are reinforced with reinforcing prisms, reinforcing rings, and modified ultra-high molecular weight polyethylene carbon fiber, increasing their strength and enabling them to puncture tires of various models. A connecting rod links several puncture triangular nails, creating a chain reaction that cushions the impact and stops the vehicle. The device is lightweight, portable, and easy to deploy. It punctures the tire, releasing air within seconds, and simultaneously entangles the wheel, forcing the vehicle to slow down and stop. It possesses excellent technical practicality and application value.
