Abstract
Description
Technical Field
[0001] This utility model relates to a tetrahedral vehicle blocking cone and a row of vehicle blocking devices, belonging to the field of police equipment technology. Background Technology
[0002] To stop illegal vehicles or prevent them from illegally entering specific areas, traffic cones are widely used as a simple and effective road barrier. Their main function is to physically block vehicles, forcing them to slow down, turn, or stop, thereby stopping them and protecting key areas or facilities. However, traditional traffic cones suffer from problems such as structural instability, insufficient friction, and excessive stopping distance, failing to effectively prevent vehicles from advancing and causing damage to people or facilities. Therefore, researching a new type of traffic cone and a series of traffic cone blocking devices is of great practical significance. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a tetrahedral vehicle blocking cone and a series of vehicle blocking devices.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a tetrahedral vehicle blocking cone, comprising six support rods, with one end of every three support rods intersecting and connecting at a point to form a tetrahedral structure, and the support rods at the connection position extending outward by a certain length to form a protrusion.
[0005] Furthermore, the included angle α between the three support rods that are intersected and connected at a point is 60°, and the six support rods are of the same length, with each support rod extending outward from the connection position to the same length.
[0006] Furthermore, the outward extension length L1 of the support rod is 0.08-0.12 times the length L of the support rod.
[0007] Furthermore, each face of the tetrahedral structure is provided with a reinforcing rod, and the first and second ends of the reinforcing rods are respectively connected to the two support rods on the triangular face in which they are located.
[0008] Furthermore, the connection angle between the first end of the reinforcing rod and one of the support rods is 90 degrees, and the connection angle between the second end of the reinforcing rod and the other support rod is 30 degrees.
[0009] Furthermore, the distance L2 from the connection point of the first end to the support rod to the end of the support rod is 0.35-0.45 times the length L of the support rod, and the distance L2 from the connection point of the first end to the support rod to the end of the support rod is equal to the distance L3 from the connection point of the second end to the support rod to the end of the support rod.
[0010] Furthermore, both the first and second ends of the reinforcing rod extend outward by a certain length, and the vertical height K1 of the outward extension of the first end and the vertical height K2 of the outward extension of the second end are equal to the vertical height K3 of the outward extension of the support rods on both sides of the triangular face connection position.
[0011] Furthermore, both the support rod and the reinforcing rod are hollow structures, and both are equipped with reinforcing ribs inside.
[0012] Furthermore, both the support rod and the reinforcing rod are coated with reflective paint.
[0013] This utility model also provides a row of vehicle blocking devices, including a plurality of the above-mentioned tetrahedral vehicle blocking cones, with adjacent vehicle blocking cones connected by ropes.
[0014] The beneficial effects of this utility model are:
[0015] During the process of stopping a vehicle with a traffic cone, the cone is easily pushed backward by the vehicle's forward force. This application, by setting protrusions, firstly ensures that three protrusions are always in contact with the ground. Compared to existing traffic cones, the traffic cone described in this application has greater friction with the ground, thereby increasing the vehicle's forward resistance and achieving a better stopping effect, effectively shortening the stopping distance. Secondly, when stopping a high-speed vehicle, the friction between the traffic cone and the ground is insufficient to overcome the vehicle's forward force. At this time, during the process of the traffic cone being pushed, compared to existing traffic cones, this application fully considers the vehicle's dynamic characteristics and impact force. The traffic cone easily flips around the protrusions when reversing, guiding the vehicle upward along the support rod as it continues to move forward. This allows the traffic cone to penetrate under the vehicle, directly lifting it off the ground for direct stopping. Furthermore, when the vehicle is lifted off the ground, the large contact area between the protrusions and the bottom of the vehicle better supports the vehicle and reduces the probability of sideslip.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0024] Example 1
[0025] like Figure 1-2 As shown, this utility model provides a tetrahedral vehicle braking cone, comprising six support rods 1. Three support rods 1 are connected at one end to form a tetrahedral structure. The support rods 1 at the connection points extend outwards by a certain length to form protrusions 2. It should be noted that the support rods 1 are fixed together by welding, preferably using argon arc welding.
[0026] During the process of stopping a vehicle with a traffic cone, the traffic cone is easily pushed backward by the vehicle due to the force of its forward movement. This application addresses this by providing protrusions 2. First, it ensures that three protrusions 2 are always in contact with the ground. Compared to existing traffic cones, the traffic cone described in this application has greater friction with the ground, thus increasing the vehicle's forward resistance and achieving a better stopping effect, effectively shortening the stopping distance. Second, when stopping a high-speed vehicle, the friction between the traffic cone and the ground is insufficient to overcome the vehicle's forward force. In this case, during the process of the traffic cone being pushed, compared to existing traffic cones, this application fully considers the vehicle's dynamic characteristics and impact force. The traffic cone easily flips around the protrusions 2 when reversing, guiding the vehicle upward along the support rod 1 as it continues to move forward. This allows the traffic cone to penetrate under the vehicle, directly lifting it off the ground for direct stopping. Furthermore, when the vehicle is lifted off the ground, the large contact area between the protrusions 2 and the bottom of the vehicle better supports the vehicle and reduces the chance of sideslip.
[0027] Specifically, such as Figure 2 As shown, the included angle α between the three support rods 1 that are intersected and connected at a point is 60°, and all six support rods 1 are of the same length. The length of each support rod 1 extending outward from the connection point is the same. Through the above settings, the stability and balance of the tetrahedral structure of the vehicle blocking cone described in this application are ensured, which can bring the same stopping performance in any placement state. Furthermore, by setting the included angle and length to be the same, the four faces are kept consistent in size, which greatly reduces the manufacturing difficulty and improves the manufacturing efficiency. In addition, by setting the same outward extension length, the friction force between the vehicle blocking cone and the ground is ensured to be evenly distributed. Because the parameters of each face are the same, in emergency situations, the vehicle blocking cone described in this application can be quickly deployed without distinguishing between the working surface and the ground surface, which is conducive to quickly handling emergencies.
[0028] Specifically, such as Figure 2As shown, the outward extension length L1 of the support rod 1 is 0.08-0.12 times the length L of the support rod 1. The limitation of this parameter directly affects the pressure-bearing performance of the protrusion 2 and even the entire vehicle cone. If the outward extension length L1 of the support rod 1 is less than 0.08 times the length L of the support rod 1, the protrusion size of the protrusion 2 is too small, which increases the manufacturing difficulty and is not conducive to providing stable support for the vehicle when it is lifted off the ground. In addition, the middle part of the support rod 1 is prone to deformation and bending, affecting the stopping effect. If the extension length L1 is greater than 0.12 times the length L of the support rod 1, although the vehicle cone is not easily deformed, the welding quality requirements at the connection are high, which is not conducive to improving manufacturing efficiency. Furthermore, the excessively long protrusion 2 does not have enough rigidity to resist lateral bending, resulting in a short service life of the vehicle cone. It will also occupy more space during transportation and storage, increasing logistics costs and storage difficulty. Only when the extension length L1 is 0.08-0.12 times the length L of the support rod 1 can the manufacturing difficulty be reduced and the local structural strength be improved while ensuring the stopping performance.
[0029] Specifically, such as Figure 1-2 As shown, each face of the tetrahedral structure is provided with a reinforcing rod 3. The first end 31 and the second end 32 of the reinforcing rod 3 are respectively connected to the two support rods 1 of the triangular face to which it belongs. It should be noted that the reinforcing rod 3 and the support rod 1 are fixed by welding, preferably by argon arc welding. By setting the reinforcing rod 3, the structural stability of the vehicle stop cone is further enhanced, forming a more stable triangular support structure and greatly improving the resistance to deformation. Furthermore, the connection angle between the first end 31 of the reinforcing rod 3 and one of the support rods 1 is 90 degrees, and the connection angle between the second end 32 of the reinforcing rod 3 and the other support rod 1 is 30 degrees. By setting the connection angle, the reinforcing rod 3 can better disperse external forces, improve the load-bearing capacity of the overall structure, and ensure that when any face is near the ground, a reinforcing rod 3 is vertically connected to one of the three support rods 1 that make up that face. This arrangement can improve the torsional resistance of the vehicle stop cone, further ensure the local structural strength, avoid deformation, and extend the service life.
[0030] Specifically, such as Figure 2As shown, the distance L2 from the connection point of the first end 31 and the support rod 1 to the end of the support rod 1 is 0.35-0.45 times the length L of the support rod 1. The distance L2 from the connection point of the first end 31 and the support rod 1 to the end of the support rod 1 is equal to the distance L3 from the connection point of the second end 32 and the support rod 1 to the end of the support rod 1. By setting the reinforcing rod 3 to be offset from the center of the support rod 1, stress concentration at the center of the support rod 1 can be avoided, which can lead to deformation and bending. If the distance L2 from the connection point of the first end 31 and the support rod 1 to the end of the support rod 1 is less than 0.35 times the length L of the support rod 1, the reinforcing rod 3 is too close to the connection point of the support rod 1, and the reinforcement effect on the structure is not significant. During the vehicle blocking process, the stress will affect the connection point of the support rod 1, causing cracking and damage at the connection point. If the distance L2 is greater than 0.45 times the length L of the support rod 1, although the structural strength is improved, the corresponding reinforcing rod 3 is prone to causing deformation and bending at the center of the support rod 1 during the vehicle blocking process. This can also lead to damage to the vehicle blocking cone; only when the distance L2 from the connection point of the first end 31 and the support rod 1 to the end of the support rod 1 is 0.35-0.45 times the length L of the support rod 1 can the service life be ensured while enhancing the structural strength.
[0031] Specifically, such as Figure 2 As shown, both the first end 31 and the second end 32 of the reinforcing rod 3 extend outward by a certain length, and the vertical height K1 of the outward extension of the first end 31 and the vertical height K2 of the outward extension of the second end 32 are equal to the vertical height K3 of the outward extension of the support rods 1 on both sides of the triangular face connection position. This arrangement increases the contact area between the vehicle-stopping cone and the ground, further increasing the friction between the vehicle-stopping cone and the ground, thereby achieving a better stopping effect and improving the stability and balance of the vehicle-stopping cone when subjected to external impact.
[0032] Specifically, such as Figure 3 As shown, both the support rod 1 and the reinforcing rod 3 are hollow structures, and both are equipped with reinforcing ribs 4 inside. It should be noted that the reinforcing ribs 4 can be cross-shaped or triangular-shaped. In this embodiment, a cross-shaped reinforcing rib 4 is used. In actual production, the shape of the reinforcing rib 4 can be designed according to performance requirements and is not limited to the cross-shaped reinforcing rib 4 described in this embodiment. By setting the reinforcing ribs 4, not only is the weight of the vehicle cone reduced, but its resistance to deformation is further improved.
[0033] Specifically, in order to improve the visibility of the traffic cones at night or in low-light conditions, the support rod 1 and the reinforcing rod 3 are coated with reflective paint. This design allows drivers to see the traffic cones clearly from a distance, thus slowing down and avoiding them in advance.
[0034] Example 2
[0035] To meet the needs of vehicle blocking in different scenarios, this utility model provides a row of vehicle blocking devices, including several tetrahedral vehicle blocking cones as described in Embodiment 1, with adjacent vehicle blocking cones connected by ropes. Through this arrangement, the vehicle blocking cones described in this application can be combined into vehicle blocking devices of different lengths and shapes as needed, flexibly adapting to various road environments and traffic demands.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are exhaustively listed. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these modifications and improvements are all within the protection scope of this utility model.
