Description

Technical Field

[0001] This utility model relates to the field of road traffic facilities technology, and in particular to a collision prevention and safety isolation device. Background Technology

[0002] Security barriers are used to separate roads, creating a separation between pedestrians and vehicles, and preventing accidents. Common security barriers include bollards and guardrails. Bollards rely on their own weight to sit on the ground and mitigate the impact of vehicles, stopping them from moving. However, recent incidents of vehicles ramming into schools demonstrate that current security barriers are not ideal in preventing such collisions. Vehicles often break through bollards and continue ramming, further exacerbating injuries and property damage. Furthermore, some vehicles remain capable of driving after a collision and flee the scene, complicating arrest efforts. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a collision prevention and security isolation device that is more effective in stopping ramming vehicles, helps reduce casualties and property damage, and facilitates timely capture.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an anti-collision security isolation device, including a ceramic shell and a blocking assembly installed in the ceramic shell; the blocking assembly includes a vertically arranged column in the ceramic shell, and the upper and lower ends of the column are respectively fixed with spike structures, each of the spike structures including a plurality of circumferentially arranged spike rods; a blocking connection structure is provided between the column and the ceramic shell.

[0005] As a preferred technical solution, the connection-rejection structure includes a connecting horizontal bar that is radially installed through the middle of the column, with both ends of the connecting horizontal bar extending out of the ceramic shell; the ceramic shell and the column are respectively provided with shell insertion holes and column insertion holes adapted to the connecting horizontal bar; the connecting horizontal bar is provided with internal insertion limiting structures at both ends of the column insertion holes, and the connecting horizontal bar is provided with external insertion limiting structures at the outer ends of the two shell insertion holes on the ceramic shell.

[0006] As a preferred technical solution, the two ends of the connecting strip extending out of the ceramic shell are respectively provided with connecting holes, the connecting holes are used to connect the intermediate connecting strip, and the end of the intermediate connecting strip near the ceramic shell also serves as the outer fitting limiting structure.

[0007] As a preferred technical solution, the ceramic shell includes a lower shell for accommodating the lower piercing structure and an upper shell for accommodating the upper piercing structure. The upper part of the lower shell is integrally provided with a supporting shell, the outer diameter of which is smaller than the outer diameter of the upper shell and the lower shell. The top of the upper shell is integrally provided with an upper shell support platform, and the upper shell rests on the upper shell support platform.

[0008] As a preferred technical solution, a spiked mounting sleeve is fixedly installed on the upper end of the column, and a plurality of circumferentially arranged spiked rods are fixedly installed on the spiked mounting sleeve. A spiked mounting structure is provided between the spiked mounting sleeve and the column.

[0009] As a preferred technical solution, the piercing end of the piercing rod is provided with a vent hole, the piercing rod is provided with a vent channel communicating with the vent hole, and the piercing rod is provided with a vent outlet on the side wall of the vent channel.

[0010] As a preferred technical solution, a traveling assembly is installed on the column, and a lifting and lowering operating mechanism is provided between the traveling assembly and the column.

[0011] As a preferred technical solution, the column is hollow, and the walking assembly includes a lifting guide rod slidably installed in the column. The end of the lifting guide rod extending out of the lower end of the column is fixedly provided with a walking mounting seat, and at least three circumferentially arranged walking wheels are installed on the walking mounting seat.

[0012] As a preferred technical solution, the lifting and lowering operating mechanism includes a lifting and lowering transmission screw fixedly disposed on the top surface of the lifting and lowering guide rod, a lifting and lowering transmission sleeve rotatably installed inside the column and threadedly engaged with the lifting and lowering transmission screw, a lifting and lowering transmission worm gear fixedly disposed on the outer periphery of the lifting and lowering transmission sleeve, a lifting and lowering transmission worm gear rotatably mounted on the column and constantly meshing with the lifting and lowering transmission worm gear, a lifting and lowering operating hole provided at one end of the lifting and lowering transmission worm gear, the lifting and lowering operating hole being used to insert a lifting and lowering operating handle, and a lifting and lowering operating clearance opening corresponding to the lifting and lowering operating handle provided on the ceramic outer shell.

[0013] Due to the adoption of the above technical solution, the anti-collision safety isolation device includes a ceramic shell and a deterrent assembly installed inside the ceramic shell. The deterrent assembly includes a vertically arranged column inside the ceramic shell, with a spike structure fixed at the upper and lower ends of the column. Each spike structure includes several circumferentially arranged spike rods. A deterrent connection structure is provided between the column and the ceramic shell.

Furthermore, after puncturing, the deterrent assembly, which itself has no rolling ability, will lift the vehicle body, causing the vehicle's drive wheels to leave the ground and stop moving quickly. This creates a stronger stopping effect on impacting vehicles, helping to reduce casualties and property damage, and facilitating timely capture. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0025] like Figures 1 to 6 As shown, the anti-collision safety isolation device includes a ceramic shell 1 and a deterrent assembly 2 installed inside the ceramic shell 1. The deterrent assembly 2 includes a vertically arranged column 21 inside the ceramic shell 1. The upper and lower ends of the column 21 are respectively fixed with spike structures 3, each spike structure 3 including several circumferentially arranged spike rods 31. A deterrent connection structure 4 is provided between the column 21 and the ceramic shell 1. In this embodiment, the deterrent assembly 2 is installed inside the fragile ceramic shell 1, forming the appearance of an isolation pier, and can therefore be used as an isolation device at a designated location. The deterrent assembly 2 has a double-headed ring spike structure. After being impacted, the deterrent assembly 2 can be quickly exposed from the broken ceramic shell 1, and the double-headed ring spike structure forms a relatively significant supporting capacity between the impacting vehicle and the ground, thereby creating multiple points of piercing the impacting vehicle and achieving the purpose of deterring the impacting vehicle.

[0026] The piercing rods 31 in each of the piercing structures 3 can be three, four, or more, such as Figure 2 and Figure 4As shown in the illustrations, four are used in each embodiment. The piercing rod 31 can be a rod-shaped structure with a sharp end, or it can be a sharp structure welded to the end of a tube; there is no limitation here. Preferably, a supporting diagonal rod 32 is provided between the piercing rod 31 and the column 21 to improve the deformation resistance of the piercing rod 31 and promote a better piercing effect.

[0027] Preferably, the puncture rod 31 has a vent hole 311 on its puncture end, a vent channel 312 communicating with the vent hole 311 inside the puncture rod 31, and a vent outlet 313 on the side wall of the vent channel 312. Thus, when the puncture rod 31 punctures a tire or other part, the vent hole 311, the vent channel 312, and the vent outlet 313 can be used to cause instantaneous deflation of the tire, further improving the deterrent effect and hindering vehicle escape.

[0028] like Figure 1 and Figure 3 As shown, the blocking connection structure 4 in this embodiment includes a connecting crossbar 41 radially penetrating and installed at the middle of the column 21. Both ends of the connecting crossbar 41 extend out of the ceramic housing 1. The ceramic housing 1 and the column 21 are respectively provided with housing insertion holes 42 and column insertion holes 43 adapted to the connecting crossbar 41. The connecting crossbar 41 has internal insertion limiting structures 44 at both ends of the column insertion holes 43, and external insertion limiting structures 45 at the outer ends of the two housing insertion holes 42 on the ceramic housing 1. Through the insertion of the connecting crossbar 41 and the internal and external limiting structures, the blocking assembly 2 is installed within the ceramic housing 1.

[0029] The connecting crossbar 41 is preferably made of a rectangular iron bar, such as an iron bar with a cross-sectional size of 5cm × 1cm. The inner fitting limiting structure 44 includes a U-shaped plate 441 that is snapped onto the connecting crossbar 41, and an inner limiting connecting pin 442 is inserted between the U-shaped plate 441 and the connecting crossbar 41; the inner limiting connecting pin 442 is inserted to connect the U-shaped plate 441 and block the end of the column fitting hole 43, thereby playing an inner limiting role.

[0030] Preferably, the connecting strip 41 has connecting holes 46 at both ends extending from the ceramic shell 1. These connecting holes 46 are used to connect the intermediate connecting strip 5. The end of the intermediate connecting strip 5 near the ceramic shell 1 also serves as the external fitting limiting structure 45, thereby simplifying the structure of a single isolation device. Furthermore, by connecting the intermediate connecting strip 5, as... Figure 8As shown, multiple isolation devices can form a long-distance isolation facility. Thus, when a vehicle collision occurs, regardless of whether it hits an isolation device or the intermediate connecting strip 5, this continuous isolation facility can be driven to move closer to the vehicle as a whole under the impact. After the ceramic shell 1 collides with the vehicle body and breaks, the exposed blocking assembly 2 together forms a puncture to the vehicle, further improving the blocking effect.

[0031] The intermediate connecting strip 5 is preferably made of iron with a rectangular cross-section to improve the connection strength and reduce the impact of impact breakage on the puncture resistance of this embodiment. The connections between the connecting crossbars 41 of the intermediate connecting strip 5, and between adjacent intermediate connecting strips 5, can be made using bolts or locks, etc., without limitation. Multiple connecting holes 46 are preferably arranged on the intermediate connecting strip 5. When at least two intermediate connecting strips 5 need to be connected between two adjacent isolation devices, suitable connecting holes 46 can be selected between the two connected intermediate connecting strips 5 to meet the arrangement requirements of different spacings of the isolation devices.

[0032] like Figure 1 As shown, the ceramic outer shell 1 includes a lower shell 11 for accommodating the lower piercing structure 3 and an upper shell 12 for accommodating the upper piercing structure 3. A supporting shell 13 is integrally provided on the upper part of the lower shell 11. The outer diameter of the supporting shell 13 is smaller than the outer diameters of the upper shell 12 and the lower shell 11. An upper shell support platform 14 is integrally provided on the top of the upper shell 12, and the upper shell 12 rests on the upper shell support platform 14. Therefore, the smaller outer diameter of the middle supporting shell 13 in the ceramic outer shell 1 allows for a shorter length of the connecting crossbar 41, reducing the impact of the connecting crossbar 41 on the piercing of the piercing structure 3.

[0033] The ceramic outer shell 1 consists of two parts. The deterrent assembly 2 can be installed on the supporting shell 13 and then covered by the upper shell 12 to form an integral block-like structure. Both the upper shell 12 and the lower shell 11 form a cover-like structure. The difference is that the top of the lower shell 11 is open in the middle to communicate with the inner cavity of the supporting shell 13, while the top of the upper shell 12 is closed to create a closed environment inside the shell. This closed top allows security personnel to stand on it for surveillance, enabling them to quickly detect dangers and direct people to safety in crowded areas and traffic.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, a spike mounting sleeve 33 is fixedly installed on the upper end of the column 21. Several circumferentially arranged spike rods 31 are fixedly arranged on the spike mounting sleeve 33. A spike mounting structure 34 is provided between the spike mounting sleeve 33 and the column 21. The spike structure 34 on the upper part forms a detachable structure, which is beneficial to meet the installation requirements of the denial assembly 2.

[0035] The piercing installation structure 34 includes a lower step 341 of the mounting sleeve, which is fixedly mounted on the column 21 and located below the piercing installation sleeve 33. A mounting nut 342 is threaded onto the upper part of the piercing installation sleeve 33 on the column 21. When the mounting nut 342 is tightened, it, together with the lower step 341, clamps the piercing installation sleeve 33, thus fixing the piercing installation sleeve 33 in place. In actual installation, threads are machined upwards from the lower step 341 on the outer circumference of the column 21. The lower step 341 is also a nut threaded onto the column 21, and the piercing installation sleeve 33 is also threaded onto the column 21. Therefore, after the mounting nut 342 is tightened, the upper piercing structure 3 can form a more rigid whole with the column 21, facilitating successful piercing.

[0036] In addition to the above structures, such as Figure 1 and Figure 7 As shown, a walking assembly 6 is also installed on the column 21, and a lifting and lowering mechanism 7 is provided between the walking assembly 6 and the column 21. The walking assembly 6 is lowered by the lifting and lowering mechanism 7, extending out from the bottom of the ceramic shell 1. This is equivalent to the ceramic shell 1 being lifted along with the blocking assembly 2. Therefore, in this embodiment, the walking assembly 6 can generate walking capability, facilitating movement. After moving to the designated position, the walking assembly 6 is raised by the lifting and lowering mechanism 7, and the ceramic shell 1 descends along with the blocking assembly 2 until it rests back on the ground, completing the relocation operation.

[0037] In this embodiment, the column 21 is hollow. The walking assembly 6 includes a lifting guide rod 61 slidably installed within the column 21. A walking mounting seat 62 is fixedly provided on the end of the lifting guide rod 61 extending out of the lower end of the column 21. At least three circumferentially arranged walking wheels 63 are mounted on the walking mounting seat 62. Preferably, a circumferential limiting structure 64 is provided between the lifting guide rod 61 and the column 21 to promote that the lifting guide rod 61 only slides axially within the column 21, thus promoting walking stability. The circumferential limiting structure 64 can be implemented using a key, an axial pin, or a radial screw, etc. This embodiment only illustrates an axial pin.

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, the lifting and lowering operation mechanism 7 includes a lifting and lowering transmission screw 71 fixedly mounted on the top surface of the lifting and lowering guide rod 61. A lifting and lowering transmission sleeve 72, which is threadedly engaged with the lifting and lowering transmission screw 71, is rotatably installed inside the column 21. A lifting and lowering transmission worm gear 73 is fixedly mounted on the outer periphery of the lifting and lowering transmission sleeve 72. A lifting and lowering transmission worm 74, which is constantly meshed with the lifting and lowering transmission worm gear 73, is rotatably mounted on the column 21. One end of the lifting and lowering transmission worm 74 is provided with a lifting and lowering operation hole 75 for inserting a lifting and lowering operation handle 76. The ceramic housing 1 is provided with a lifting and lowering operation clearance opening 77 corresponding to the lifting and lowering operation handle 76.

[0039] During operation, the lifting and lowering operating handle 76 is inserted into the ceramic housing 1 and connected to the lifting and lowering operating hole 75. Rotating the lifting and lowering operating handle 76 from the outside causes the lifting and lowering transmission worm gear 73 and the lifting and lowering transmission worm 74 to rotate the lifting and lowering transmission screw sleeve 72. This screw sleeve, in turn, engages with the lifting and lowering transmission screw 71, causing the traveling assembly 6 to lift and lower. When the lifting and lowering operating handle 76 rotates forward, the traveling assembly 6 lowers; when it rotates in the reverse direction, it raises. Regardless of when the lifting and lowering operating handle 76 is stopped, the self-locking properties of the lifting and lowering transmission worm gear 73 and the lifting and lowering transmission worm 74, as well as the self-locking properties of the lifting and lowering transmission screw sleeve 72 and the lifting and lowering transmission screw 71, ensure that the traveling assembly 6 remains stably at a fixed height, thus promoting reliable movement operations. The lifting and lowering operation hole 75 can be implemented by a hole or groove with a polygonal cross-section. Correspondingly, the lifting and lowering operation handle 76 is provided with a polygonal protrusion that matches the lifting and lowering operation hole 75, so that the handle can be rotated and operated after being inserted.

[0040] In this embodiment, during assembly, firstly, the walking assembly 6 and the parts of the lifting and lowering operating mechanism 7, excluding the lifting and lowering operating handle 76, are assembled onto the column 21. The supporting housing 13 and the lower housing 11 are then fitted over the column 21. The column 21 is raised until the connecting crossbar 41 can be sequentially installed through the height between the supporting housing 13 and the column 21. After the connecting crossbar 41 is installed, the inner fitting limiting structure 44 is installed for inner limiting. Then, the upper piercing structure 3 is installed. Finally, the upper housing 12 is placed over the upper housing support platform 14, completing the assembly of the isolation device. After assembly, the isolation device is stored and transported as a whole.

[0041] In use, the lifting and lowering mechanism 7 is used to switch to walking mode and move to the designated location; the intermediate link 5 connects adjacent isolation devices to form a common isolation facility. After connecting the intermediate link 5, the lifting and lowering mechanism 7 is used to bring the ceramic shell 1 back to the ground, thus achieving the isolation function. Warning strips can be affixed to both the ceramic shell 1 and the intermediate link 5, with warnings such as "Personnel and Vehicle Separation" and "Violation Will Be Prosecuted," and are made of reflective material for easy visibility at night.

[0042] The height of the isolation device is preferably 50-60cm, more preferably 55cm. When a vehicle rams into it, whether it hits the isolation device or the intermediate connecting strip 5, a collision between the isolation device and the vehicle body will eventually occur. After the collision, the ceramic outer shell 1 breaks, exposing the internal blocking assembly 2. The blocking assembly 2 with its double-headed ring spike structure can easily puncture the vehicle body, especially the bottom, by relying on its ground support and its low height. Components such as the vehicle's water tank, tires, and fuel tank are highly likely to be punctured, causing the vehicle to quickly lose some of its functions. Furthermore, after puncturing, the blocking assembly 2, which does not have the ability to roll, will cause the vehicle body to lift off the ground, causing the vehicle's drive wheels to leave the ground and stop moving quickly. This creates a stronger stopping effect on ramming vehicles, which helps reduce casualties and property damage and facilitates timely capture.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
