Description

Technical Field

[0001] This utility model belongs to the technical field of road traffic enforcement facilities, specifically relating to a slotted, venting, 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, portable, puncture-proof tire-breaking cone police vehicle stopper. It employs a three-conical-pointed puncture-proof triangular nail structure, significantly improving the stability of the tire-breaking device. By creating puncture grooves on the conical points, the device rapidly deflates the tire, causing the car to stop quickly and effectively stopping the vehicle. A connecting rod links several puncture-proof triangular nails, creating a chain reaction that cushions the tire and stops the vehicle. Modified Kevlar carbon fiber reinforces the triangular nails, increasing their strength and enabling them to puncture tires of various models. The overall structure of the vehicle stopper is lightweight, easy to carry, and convenient to deploy. Its easily puncturable outer shell punctures the tire, releasing air within seconds and simultaneously entangling 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 slotted, venting, portable explosive cone for police vehicles includes an elongated triangular bar. Inside the elongated triangular bar is a triangular nail tire puncturer. The triangular nail tire puncturer includes a tire-puncturing triangular nail and a connecting rod that penetrates and connects to the tire-puncturing triangular nail. The tire-puncturing triangular nail has three conical tips forming a triangle, with slotted venting holes penetrating within each conical tip. A connecting rod connection hole for mounting the connecting rod is penetrating the center of the tire-puncturing triangular nail.

[0007] Preferably, the elongated triangular bar has a tire puncture device storage cavity running through its interior, and a tire stop friction strip and a tire stop reflective strip connected to its outer surface. The triangular nail tire puncture device is installed in the tire puncture device storage cavity.

[0008] 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.

[0009] Preferably, the straight-line distance between the conical tips of the tire puncture triangular nail is 10-100 mm, and the lower width of the groove-type vent hole is 1-10 mm, and the length of the hypotenuse is 3-25 mm.

[0010] Preferably, the tapered tip of the tire puncture triangular nail is integrated with the tire puncture triangular nail and has a thickness of 1-10mm, with the tip of the tapered tip being a rhomboid pyramid tip.

[0011] Preferably, the slotted vent hole is filled with a slotted porous reinforcing block of the same shape as the slotted vent hole, and the slotted porous reinforcing block is movably connected to the tire puncture triangular nail.

[0012] Preferably, the triangular nail connecting rod is provided with multiple sections, and each section has a connecting welding end at both ends. The connecting welding end is inserted into the connecting hole of the connecting rod of the tire-puncture triangular nail and welded to the tire-puncture triangular nail.

[0013] Preferably, there is a connecting deceleration bar between the connecting and welding ends of the triangular nail connecting rod. The connecting deceleration bar is connected to the tire-puncture triangular nail by an integrated connecting and welding end. The connecting deceleration bar is configured as one of the following: connecting chain, connecting soft steel bar, connecting strong rope, and connecting spring, forming a deceleration barrier with the tire-puncture triangular nail.

[0014] Preferably, the outer surface of the conical tip of the tire puncture nail is wrapped with ceramic-based modified Kevlar carbon fiber, and the coverage length of the ceramic-based modified Kevlar carbon fiber at the conical tip is the same as the length of the hypotenuse of the groove-type vent hole.

[0015] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a slotted, venting, portable explosive cone police vehicle stopper, the beneficial effects of which are: The tire puncture device in this vehicle stopper employs a three-conical-angled puncture triangular nail structure, significantly enhancing its stability. Air release grooves on the conical angles allow for rapid deflation of the tire, forcing the car to stop quickly and effectively stopping the vehicle. A linkage connects several puncture triangular nails, creating a chain reaction that cushions the impact and brings the vehicle to a stop. Modified Kevlar carbon fiber reinforces the triangular nails, increasing their strength and enabling them to puncture tires of various models. The vehicle stopper is lightweight, easy to carry, and convenient to deploy. Its easily puncturable outer shell punctures the tire, releasing air within seconds and simultaneously entangling the wheel, forcing the vehicle to slow down and stop. It possesses excellent technical practicality and application value. Attached Figure Description

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

[0020] like Figure 1 , 2As shown, a slotted, venting, 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 passes through and 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 that all the 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 pass through the elongated triangular rod 1 under pressure, puncturing the tire.

[0021] like Figure 1 , 2 As shown in Figure 3, a slotted venting portable explosive cone police vehicle stopper includes a tire-puncture triangular nail 3 comprising three triangularly shaped conical tips 6. A slotted venting hole 7 is perforated within each conical tip 6. A connecting rod connecting hole 8 for mounting a connecting rod 4 is perforated in the middle of the tire-puncture triangular nail 3. A slotted porous reinforcing block of the same shape as the slotted venting hole 7 is filled within the slotted venting hole 7 and is movably connected to the tire-puncture triangular nail 3. The outer surface of the conical tips 6 of the tire-puncture triangular nail 3 is wrapped with ceramic-based modified Kevlar carbon fiber, the coverage length of which is the same as the hypotenuse length of the slotted venting hole 7. The triangular nail connecting rod 4 has multiple segments, each segment having two ends... The device is equipped with a connecting welding end, which is inserted into the connecting hole 8 of the connecting rod of the tire puncture triangular nail 3 and welded to the tire puncture triangular nail 3. The three pyramidal pointed tips 6 on the tire puncture triangular nail 3 are very sharp and can directly puncture the elongated triangular rod 1 under pressure to puncture the tire. The grooved vent hole 7 on the pointed tip 6 can directly vent the tire after the device punctures the tire. A grooved porous reinforcing block can be set in the grooved vent hole 7, which can not only improve the strength and rigidity of the pointed tip 6 and prevent the pointed tip 6 from breaking under the pressure, but also allow for slow venting and reduce the inertia of the car. The outer surface of the pointed tip 6 can be wrapped with ceramic-based modified Kevlar carbon fiber, which can also improve its strength and rigidity.

[0022] like Figure 4 , 5As shown, a slotted, venting, portable explosive cone police vehicle stopper is described. An elongated triangular bar 1 has a tire puncture device storage cavity 5 running through its interior, and a tire stopper friction strip 9 and a tire stopper reflective strip 10 connected to its outer surface. A triangular nail tire puncture device 2 is installed in the tire puncture device storage cavity 5. The tire puncture device 2 is perfectly positioned within the storage cavity 5 of the elongated triangular bar 1, preventing it from becoming loose. The tire stopper friction strip 9 and reflective strip 10 on the elongated triangular bar 1 serve two purposes: first, to improve the friction performance of the elongated triangular bar 1, providing a good cushioning effect; and second, to make it highly visible, preventing drivers from failing to see the tire puncture device and speeding past, which could lead to a sudden tire puncture and vehicle rollover.

[0023] 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 6 of the tire puncture triangular nails 3 is 10-100 mm. The lower width of the slotted vent hole 7 is 1-10 mm, and the length of the hypotenuse is 3-25 mm. The tail end of the conical tip 6 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 6 is set as a rhomboid pyramid tip.

[0024] Furthermore, there is a connecting deceleration bar between the connecting and welded 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 welded end. The connecting deceleration bar is set to be one of the following: connecting chain, connecting soft steel bar, connecting strong rope, or connecting spring. It forms a deceleration barrier with the tire-puncture triangular nail 3. The tire-puncture triangular nail 3 and the multi-segment triangular nail connecting rod 4 form a deceleration barrier. Different triangular nail connecting rods 4 can be selected according to the actual situation to improve the overall anti-buffering deceleration effect.

[0025] The working principle is as follows: During transport, the triangular nail tire puncture device 2 is placed directly in 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, the elongated triangular bar 1 together with the triangular nail tire puncture device 2 is placed directly on the road where tire punctures need to be prevented. The elongated triangular bar 1 is equipped with a tire stop friction strip 9 and a tire stop reflective strip 10. The tire stop friction strip 9 improves the friction performance of the elongated triangular bar 1 and can play a good buffering role. The tire stop reflective strip 10 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 always 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 its three conical tips 6 supported by the support of the three conical tips 6. It 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 to directly puncture the long triangular bar 1, and then puncture the outer tire and inner tube of the car tire. Because the conical vent 7 has grooved vent holes 6, and even grooved porous reinforcing blocks can be installed inside the grooved vent holes 7, the inner tube of the car tire can be deflated through the grooved vent holes 7 and the grooved porous reinforcing blocks inside, allowing the car to decelerate quickly. The grooved porous reinforcing blocks can reinforce the conical vent holes 7. Because the puncture triangular nails 3 are inserted into the tire under the action of the three conical vent holes 6, the car will not stop instantly. The tire will move forward with the puncture triangular nails 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, so that the puncture triangular nails 3 and the triangular nail connecting rod 4 form a deceleration barrier, which greatly improves the deceleration effect. Example 2

[0026] The difference between this embodiment and Embodiment 1 is that: like Figure 1 , 2 As shown in Figure 3, a slotted venting portable explosive cone police vehicle stopper is provided. The tire venting triangular nail 3 includes three triangular cone-shaped sharp corners 6. A rhomboid venting protrusion is integrally provided on the cone-shaped sharp corner 6. A venting hole is provided through the rhomboid venting protrusion. After the cone-shaped sharp corner 6 is inserted into the tire, the tire is vented through the venting hole in the rhomboid venting protrusion. Example 3

[0027] The difference between this embodiment and embodiments 1 and 2 is that: like Figure 1 , 2 As shown in Figure 3, a slotted, venting, portable blasting cone police vehicle stopper includes a puncture triangular nail 3 comprising three triangular cone-shaped tips 6. Each cone-shaped tip 6 has an integrally formed prismatic venting groove. The prismatic venting groove allows the tire to be vented after the cone-shaped tip 6 is inserted into the tire. Furthermore, several venting holes can be provided on the side convex wall of the prismatic venting groove to enable rapid tire venting.

[0028] In this invention, the tire puncture device in the tire stopper adopts a three-conical-pointed puncture triangular nail structure, which greatly improves the stability of the tire puncture device. By opening air release grooves on the conical points, the tire puncture device can smoothly and quickly release air from the tire, prompting the car to stop quickly and shut off, thus playing a good role in stopping the vehicle. Several puncture triangular nails are connected by a connecting rod, and the puncture triangular nails inserted into the tire are linked together, which can buffer the car tire and stop the vehicle. The triangular nails are reinforced with modified Kevlar carbon fiber to improve their strength and enable them to puncture tires of various models. The overall structure of the tire stopper is lightweight, easy to carry, and convenient to deploy. The outer shell is easy to puncture, and the tire punctures the air inside the tire within a few seconds. At the same time, it can wrap around the wheel, forcing the vehicle to slow down and stop. It has good technical practicality and application value.
