Description

Technical Field

[0001] This utility model relates to the field of road traffic safety equipment technology, specifically to a vehicle blocking cone. Background Technology

[0002] Vehicle cones are specialized equipment used for road safety management and security interception. Their core function is to forcibly control the driving status of vehicles through physical obstruction, tire damage, and other methods, ultimately achieving the goal of "stopping vehicles and ensuring safety".

[0003] Currently, the mainstream car cones on the market are mainly divided into two categories: one is an integrated fixed structure car cone, which is mostly made of rubber, cast iron or ordinary alloy materials. The whole is conical or pyramidal in shape, and the bottom is reinforced with weights (such as cast iron bases) to enhance stability. Some products have anti-slip textures on the surface, but there is no structure to actively grip vehicles or the ground; the other is a simple folding car cone, which is mostly a 3-4 bar folding design. It is stored by connecting with hinges. The material is mainly lightweight aluminum alloy, and the "portability" problem can be solved by the folding structure.

[0004] However, the core working logic of existing traffic cones is "physical obstruction," that is, to hinder the movement of vehicles by their own weight and shape. The drawbacks are: insufficient gripping force of traffic cones, making them easy to be knocked away by vehicles and unable to effectively lock the vehicles; insufficient gripping force of traffic cones, making them easy to be pushed away and lose their stopping function; and the inability of traffic cones to lift the vehicle's tires (especially the front wheels), causing the vehicle to continue to move forward by its own power, resulting in low stopping efficiency (requiring a longer braking distance). Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a vehicle-stopping cone that can quickly and efficiently stop vehicles.

[0006] This utility model provides a vehicle blocking cone, including a cross-connection part, at least three gripping bars extending obliquely downward from the cross-connection part in different directions, and at least three vehicle grabbing bars extending obliquely upward from the cross-connection part. Each gripping bar has a gripping cone at its lower end and a vehicle grabbing cone at its upper end.

[0007] Furthermore, the gripping cone includes a plurality of first gripping cones arranged axially in the middle region of the lower end of the gripping bar, and a plurality of second gripping cones arranged inclined outward relative to the axial direction in the edge region of the lower end of the gripping bar.

[0008] The vehicle grabbing cone includes multiple first vehicle grabbing cones arranged axially in the middle region of the upper end of the vehicle grabbing rod, and multiple second vehicle grabbing cones arranged outward relative to the axial direction in the edge region of the upper end of the vehicle grabbing rod.

[0009] Furthermore, the lower end of the grip bar has a gripping plane perpendicular to the axial direction of the grip bar in the middle region, and each of the first gripping cones is vertically fixed on the gripping plane. The lower end of the grip bar has a gripping annular cone surface at a certain angle to the axial direction of the grip bar in the edge region, and each of the second gripping cones is vertically fixed on the gripping annular cone surface.

[0010] The lower end of the grabbing rod has a grabbing plane perpendicular to the axial direction of the grabbing rod in the middle area. Each of the first grabbing cones is vertically fixed on the grabbing plane. The lower end of the grabbing rod has a grabbing annular cone surface at a certain angle to the axial direction of the grabbing rod in the edge area. Each of the second grabbing cones is vertically fixed on the grabbing annular cone surface.

[0011] Furthermore, a gripping cone mounting base is fixed to the lower end of the gripping bar. The gripping plane and the gripping annular cone surface are both provided on the gripping cone mounting base. The area of ​​the gripping cone mounting base corresponding to the gripping plane is located in the end area of ​​the gripping bar, and the area of ​​the gripping cone mounting base corresponding to the gripping annular cone surface extends radially out of the end area of ​​the gripping bar.

[0012] The lower end of the grabbing rod is fixed with a grabbing cone mounting seat. The grabbing plane and the grabbing annular cone are both located on the grabbing cone mounting seat. The area of ​​the grabbing cone mounting seat corresponding to the grabbing plane is located in the end area of ​​the grabbing rod, and the area of ​​the grabbing cone mounting seat corresponding to the grabbing annular cone extends radially out of the end area of ​​the grabbing rod.

[0013] Furthermore, each of the first and second gripping cones is threadedly connected to the gripping cone mounting base and then welded and fixed to the gripping cone mounting base.

[0014] Each of the first and second grabbing cones is threadedly connected to the grabbing cone mounting seat and then welded and fixed to the grabbing cone mounting seat.

[0015] Furthermore, the number of the vehicle gripping rods corresponds one-to-one with the number of the ground gripping rods, and each pair of vehicle gripping rods and ground gripping rods are coaxial.

[0016] Furthermore, the number of grip bars and vehicle grip bars is three.

[0017] Furthermore, the cross connection includes a cross connector, which includes a central hole and U-shaped grooves extending from the central hole to the surrounding area, with the openings of each U-shaped groove facing the same side.

[0018] The pair of grip bars and grip vehicle bars are coaxially connected as a single rod, and the remaining grip bars and grip vehicle bars are folding rods. The middle part of the single rod passes through the central hole and is fixedly connected to the cross connector. The inner ends of each folding rod are hinged to each of the U-shaped grooves and can be fixed to the side plate of the corresponding U-shaped groove by locking pins.

[0019] Furthermore, a U-shaped handle is fixed to the integrated rod, with both ends of the U-shaped handle fixed to the outside of the ground grip bar and the vehicle grip bar of the integrated rod, respectively.

[0020] Furthermore, the integrated rod is provided with four magnetic attachments on the outer periphery of one end of the U-shaped groove opening, and each of the folding rods is attached and fixed to the corresponding magnetic attachment when folded up.

[0021] The beneficial effects of this utility model are reflected in:

[0022] The gripping cones at the lower ends of each gripping bar in this invention support the ground. When a vehicle collides with a parking cone, the gripping cones at the upper ends of the gripping bars instantly penetrate the vehicle's tires or chassis. The vehicle's horizontal forward force is transmitted to the parking cones through the gripping cones, causing the parking cones to generate a torque that causes the gripping cones on the opposite side of the impact direction to roll over the contact point with the ground. At the same time, the gripping cones on the opposite side of the impact direction penetrate the ground. As the vehicle continues to move forward and pushes the parking cones to roll, the gripping cones completely lock the vehicle's chassis and the ground. The rolling force lifts the front wheels of the vehicle, causing them to lift off the ground. The vehicle then loses power, thus quickly stopping the vehicle.

[0023] Therefore, when a vehicle collides with the vehicle-stopping cone of this invention, the grabbing cone pierces the vehicle's tires or chassis, and the ground-gripping cone pierces the ground. This solves the problem that existing vehicle-stopping cones have insufficient grabbing force and ground-gripping force, cannot effectively lock the vehicle, and are easily pushed away, thus losing their stopping function. At the same time, when a vehicle collides with the vehicle-stopping cone, it can cause the cone to roll. During the rolling process, the cone can lift the front wheels of the vehicle off the ground, preventing the vehicle from gaining power. This allows for quick and efficient stopping of the vehicle.

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0033] like Figures 1-5 As shown, this utility model embodiment provides a vehicle blocking cone, including a cross connection part 100, at least three gripping bars 200 extending obliquely downward from the cross connection part 100 in different directions, and at least three vehicle grabbing bars 300 extending obliquely upward from the cross connection part 100. Each gripping bar 200 has a gripping cone 210 at its lower end, and each vehicle grabbing bar 300 has a vehicle grabbing cone 310 at its upper end.

[0034] In this embodiment, the grip bar 200 and the gripping bar 300 can be made of high-strength manganese steel (yield strength ≥900MPa), and the gripping cone 210 and the gripping cone 310 can be made of heat-treated alloy steel (hardness HRC55-60).

[0035] The gripping cones 210 at the lower end of each gripping bar 200 of this utility model are supported on the ground. When the vehicle hits the stopping cone, the gripping cones 310 at the upper end of the gripping bar 300 instantly penetrate the vehicle's tires or chassis. The horizontal forward force of the vehicle is transmitted to the stopping cone through the gripping cones 310, causing the stopping cone to generate a torque around the contact point between the gripping cones 210 and the ground on the opposite side of the impact direction. At the same time, the gripping cones 210 on the opposite side of the impact direction penetrate the ground. As the vehicle continues to move forward and pushes the stopping cone to roll, the gripping cones 310 completely lock the vehicle chassis and the gripping cones 210 completely lock the ground. The rolling force lifts the front wheels of the vehicle, and the front wheels are lifted off the ground. The vehicle cannot obtain power, thereby quickly stopping the vehicle.

[0036] Therefore, when a vehicle hits the vehicle-stopping cone of this utility model, the grabbing cone 310 penetrates the vehicle's tire or chassis, and the ground-gripping cone 210 penetrates the ground. This solves the problem that existing vehicle-stopping cones have insufficient grabbing force and ground-gripping force, cannot effectively lock the vehicle, and are easily pushed away, thus losing their stopping function. At the same time, when a vehicle hits the vehicle-stopping cone, it can cause the cone to roll. During the rolling process, the cone can lift the front wheels of the vehicle off the ground, and the vehicle cannot obtain power. This allows for quick and efficient stopping of the vehicle.

[0037] In some embodiments, such as Figure 3 and Figure 4 As shown, the grip cone 210 includes a plurality of first grip cones 211 arranged axially in the middle region of the lower end of the grip bar 200, and a plurality of second grip cones 212 arranged outward relative to the axial direction in the edge region of the lower end of the grip bar 200.

[0038] Similarly, the grabbing cone 310 includes a plurality of first grabbing cones 311 arranged axially in the middle region of the upper end of the grabbing rod 300, and a plurality of second grabbing cones 312 arranged outward relative to the axial direction in the edge region of the upper end of the grabbing rod 300.

[0039] In one specific embodiment, refer to Figure 3 and Figure 4 In the initial state, the second grab cone 312 on the lower side is basically horizontal with the ground, the second gripping cone 212 on the lower side forms an angle of about 70° with the ground, the first grab cone 311 is tilted at an angle of about 34° with respect to the ground, and the gripping bar 200 forms an angle of about 36° with the ground.

[0040] When a vehicle (e.g., traveling at 30-60 km / h) collides with a vehicle-stopping cone, it first contacts the horizontally arranged second grabbing cone 312. Figure 3At the impact point 1), the second grab cone 312 instantly pierces the vehicle tire or chassis. The grab cone 310 can penetrate a 3-5mm thick metal chassis. The horizontal forward force of the vehicle is transmitted to the blocking cone through the grab cone 310, causing the blocking cone to generate a rolling torque around the contact point between the grab cone 210 and the ground.

[0041] As the vehicle continues to move forward and pushes the anti-vehicle cones to roll (rolling angle 0°→30°), the first anti-vehicle cone 311 (impact points 2 and 3), which was originally at an angle of 15°-30° to the horizontal, gradually becomes perpendicular to the vehicle surface. The depth of the tip penetrating the vehicle body increases from 2cm to more than 5cm. The penetration angle of the anti-vehicle cone 310 approaches vertical as the rolling angle increases. The anti-vehicle force is positively correlated with the impact force (the greater the impact force, the greater the rolling angle, the deeper the steel nail penetrates, and the stronger the anti-vehicle force), thus preventing the anti-vehicle cone 310 from slipping out.

[0042] Under the action of the rolling moment, the force state of the second grip cone 212 (grip point 1), which initially forms a 70° angle with the ground, changes as follows: the horizontal force of the vehicle is transformed into a "vertical force of the second grip cone 212 piercing the ground" through the vehicle stop cone (the mechanical transformation from horizontal force to vertical force, based on the principle of force decomposition: Fvertical = FHorizontal × sin70°); the second grip cone 212 instantly pierces the ground (3-5cm deep in concrete and 5-7cm deep in asphalt); as the vehicle stop cone continues to roll, grip points 2 and 3 of the first grip cone 311 pierce the ground in sequence, forming a "three-point grip", and the gripping force increases with the increase of the impact force (to prevent the vehicle stop cone from being pushed away). When the rolling angle of the vehicle-stopping cone reaches 30°-45°, the vehicle-catching cone 310 has completely locked the vehicle chassis, and the ground-grabbing cone 210 has completely locked the ground. The rolling force lifts the front wheels of the vehicle by 2-5cm (because the front wheels lose ground support, the vehicle cannot gain power). At this time, the vehicle-stopping cone forms a huge resistance through the rigid connection of "cone-vehicle-ground", which makes the vehicle stop within 1-3 seconds.

[0043] Preferably, the lower end of the grip bar 200 near the middle region has a gripping plane 221 perpendicular to the axial direction of the grip bar 200. Each first gripping cone 211 is vertically fixed on the gripping plane 221. This allows the first gripping cones 211 to be axially positioned while ensuring good force distribution. The lower end of the grip bar 200 near the edge region has a gripping annular cone surface 222 at a certain angle to the axial direction of the grip bar 200. Each second gripping cone 212 is vertically fixed on the gripping annular cone surface 222. This allows the second gripping cones 212 to be inclined outward relative to the axial direction while ensuring good force distribution.

[0044] Optionally, a gripping cone mounting base 220 is fixed at the lower end of the gripping bar 200. Both the gripping plane 221 and the gripping annular cone surface 222 are provided on the gripping cone mounting base 220. The area of ​​the gripping cone mounting base 220 corresponding to the gripping plane 221 is located in the end area of ​​the gripping bar 200, and the area of ​​the gripping cone mounting base 220 corresponding to the gripping annular cone surface 222 extends radially beyond the end area of ​​the gripping bar 200.

[0045] Similarly, the lower end of the grabbing rod 300 near the middle region is provided with a grabbing plane 321 perpendicular to the axial direction of the grabbing rod 300. Each first grabbing cone 311 is vertically fixed on the grabbing plane 321. This allows the first grabbing cone 311 to be axially positioned while ensuring that the first grabbing cone 311 is subjected to good force. The lower end of the grabbing rod 300 near the edge region is provided with a grabbing annular cone surface 322 at a certain angle to the axial direction of the grabbing rod 300. Each second grabbing cone 312 is vertically fixed on the grabbing annular cone surface 322. This allows the second grabbing cone 312 to be inclined outward relative to the axial direction while ensuring that the second grabbing cone 312 is subjected to good force.

[0046] Optionally, a grabbing cone mounting base 320 is fixed at the lower end of the grabbing rod 300. The grabbing plane 321 and the grabbing annular cone surface 322 are both provided on the grabbing cone mounting base 320. The area of ​​the grabbing cone mounting base 320 corresponding to the grabbing plane 321 is located in the end area of ​​the grabbing rod 300, and the area of ​​the grabbing cone mounting base 320 corresponding to the grabbing annular cone surface 322 extends radially out of the end area of ​​the grabbing rod 300.

[0047] In this embodiment, the gripping cone mounting base 220 is used to fix the gripping cone 210, and the vehicle grabbing cone mounting base 320 is used to fix the vehicle grabbing cone 310. They are made of the same material as the vehicle grabbing rod 300 and the gripping rod 200. The gripping cone mounting base 220 and the vehicle grabbing rod 300, and the vehicle grabbing cone mounting base 320 and the gripping rod 200 can be fixed by welding.

[0048] In some embodiments, each of the first gripping cones 211 and the second gripping cones 212 is threadedly connected to the gripping cone mounting base 220 and then welded to the gripping cone mounting base 220. This ensures that the gripping cones 210 and the gripping cone mounting base 220 are firmly connected, and that the gripping cones 210 will not fall off under an impact force of ≥50kN, thereby improving service life and stopping reliability.

[0049] Similarly, each of the first grabbing cones 311 and the second grabbing cones 312 is threaded to the grabbing cone mounting base 320 and then welded to the grabbing cone mounting base 320. This ensures that the grabbing cones 310 and the grabbing cone mounting base 320 are firmly connected, and that the grabbing cones 310 will not fall off under an impact force of ≥50kN, thereby improving service life and stopping reliability.

[0050] In some embodiments, refer to Figure 1 The number of gripping bars 300 corresponds one-to-one with the number of gripping bars 200, and each pair of gripping bars 300 and gripping bars 200 are coaxial.

[0051] In this embodiment, there are three grip bars 200 and three gripping bars 300. It is understood that in other embodiments, there are four grip bars 200 and four gripping bars 300, or other numbers.

[0052] Preferably, the cross connection 100 includes a cross connector 110, which includes a central hole 111 and U-shaped grooves 112 extending outward from the central hole 111. The openings of each U-shaped groove 112 face the same side. A pair of grip bars 200 and grip rods 300 are coaxially connected as a single rod. The remaining grip bars 200 and grip rods 300 are folding rods. The middle part of the single rod passes through the central hole 111 and is fixedly connected to the cross connector 110. The inner ends of each folding rod are hinged to each U-shaped groove 112 and can be fixed to the side plate of the corresponding U-shaped groove 112 by locking pins 120.

[0053] When folding, the locking pins 120 between each folding rod and the U-shaped groove 112 can be pulled out, and then each folding rod can be rotated on one side of the groove opening of the U-shaped groove 112 to fold the vehicle blocking cone as shown. Figure 5 The structure shown has a significantly reduced volume when folded, allowing it to be placed in a dedicated storage box for easy portability.

[0054] In use, remove the folded car cones from the storage box, then unfold each folding rod and insert the locking pins 120 to fix each folding rod to the U-shaped groove 112 (e.g., Figure 1 As shown in the image, the deployed traffic cones can be placed in the designated stopping area to stop vehicles, making them suitable for emergency scenarios (such as counter-terrorism and road inspection).

[0055] Optionally, such as Figure 1 and Figure 5 As shown, a U-shaped handle 400 is fixed on the integrated rod. The two ends of the U-shaped handle 400 are respectively fixed to the outside of the ground grip bar 200 and the vehicle grip bar 300 of the integrated rod, so that it is convenient to lift the vehicle cone through the U-shaped handle 400.

[0056] Optionally, such as Figure 1 As shown, the integrated rod has four magnetic attachments 500 on the outer periphery of one end of the opening of the U-shaped groove 112. When each folding rod is folded up, it is attached to each magnetic attachment 500. When folded, each folding rod can be magnetically attached to the outside of the integrated rod by the magnetic attachments 500, which can fix each folding rod and prevent the anti-vehicle cone from automatically spreading out after folding.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
