Description

Technical Field

[0001] This utility model belongs to the field of anti-collision plate technology, specifically relating to a high-strength impact-resistant structure for anti-collision plates. Background Technology

[0002] As a common protective component, crash barriers are widely used in various scenarios where collisions may occur, such as parking lots, factory workshops, and roadsides. Their function is to effectively absorb and disperse the impact force when a collision occurs, protecting the protected object from damage. However, traditional crash barriers have certain limitations in terms of impact resistance.

[0003] Most existing crash barriers have simple structures and cannot fully absorb energy when faced with large impacts, resulting in poor crash protection. Some crash barriers rely solely on the hardness of their material to withstand impacts, which is also ineffective. This not only makes the crash barrier itself prone to damage and deformation, but also fails to effectively protect the object being protected. Therefore, we provide a high-strength impact-resistant structure for crash barriers to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-strength impact-resistant structure for a crash barrier.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength impact-resistant structure for a crash barrier includes an I-shaped base, with two sets of limiting frames fixedly connected to the inner wall of the I-shaped base. The outer surface of the limiting frames is slidably connected to the crash barrier body. Three sets of buffer components are provided on the back of the crash barrier body, and buffer components are provided inside the limiting frames.

[0007] As a preferred embodiment, the buffer assembly includes an elastic element fixedly connected to the outer surface of the anti-collision plate body, and a fixing plate is fixedly connected to one end of the elastic element away from the anti-collision plate body.

[0008] In a preferred embodiment, the outer surface of the fixing plate is fixedly connected to the outer surface of the object being protected.

[0009] As a preferred embodiment, an elastic element two is fixedly connected to the outer surface of the fixing plate, and the elastic element two is located inside the elastic element one.

[0010] As a preferred embodiment, the second buffer component includes a limiting rod fixedly connected to the inner wall of the limiting frame, and a rubber pad is fixedly connected to the outer surface of the limiting rod.

[0011] As a preferred embodiment, a rubber pad is fixedly connected to the outer surface of the limiting rod.

[0012] In a preferred embodiment, a slider is fixedly connected to the outer surface of the limiting rod, and a bearing plate is fixedly connected to the outer surface of the slider.

[0013] In a preferred embodiment, the outer surface of the bearing plate is in contact with the outer surface of the anti-collision plate body.

[0014] As a preferred embodiment, the outer surface of the limiting rod is fitted with an elastic element three, and one end of the elastic element three is fixedly connected to the outer surface of the slider.

[0015] In a preferred embodiment, the end of the elastic element three that is away from the slider is fixedly connected to the outer surface of the rubber pad two.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) By setting buffer component two, this utility model can achieve the initial buffering and pressure relief effect on the body of the anti-collision plate. By setting buffer component one, it can achieve the multi-level buffering and pressure relief effect on the body of the anti-collision plate. Through the coordinated cooperation of various components in buffer component one and buffer component two, the impact force is absorbed and dispersed in multiple levels and stages from different stages and levels, thereby effectively protecting the protected object from damage and greatly improving the impact resistance and protection effect of the anti-collision plate.

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Please see Figures 1 to 3 As shown, this utility model embodiment provides a high-strength impact-resistant structure for a crash barrier, specifically including an I-shaped base 1. The I-shaped base 1 is typically made of high-strength metal, such as Q345 steel. This material has good strength and toughness, and can withstand large external forces without easily deforming. Its unique I-shaped design not only saves materials but also reduces its weight while ensuring structural stability, making it convenient for installation and use. Two sets of limiting frames 2 are fixedly connected to the inner wall of the I-shaped base 1. The limiting frames 2 are made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant, effectively extending its service life. The limiting frames 2 are elongated and have a smooth outer surface, slidingly connected to the crash barrier body 3. This connection method allows the crash barrier body 3 to slide smoothly along the limiting frames 2 when impacted, limiting the movement trajectory of the crash barrier body 3 and preventing it from shifting or shaking during the impact, thus ensuring the stability of the buffering effect. The outer surface of the limit frame 2 is slidably connected to the anti-collision plate body 3. The anti-collision plate body 3 is made of polyurethane material with high elasticity and wear resistance. When subjected to impact, the polyurethane material can produce large elastic deformation and absorb a large amount of impact energy. At the same time, its good wear resistance can ensure that the anti-collision plate body 3 can still maintain good performance after multiple collisions.

[0027] Please see Figure 4As shown, three sets of buffer components 4 are provided on the back of the crash barrier body 3. These three sets of buffer components 4 are evenly distributed on the back of the crash barrier body 3, which can more evenly disperse the impact force. The buffer component 4 specifically includes an elastic element 401 fixedly connected to the outer surface of the crash barrier body 3. The elastic element 401 is a helical spring structure, made of spring steel. Spring steel has a high elastic limit and fatigue limit, which can ensure that the spring is not easily fatigued and damaged during long-term expansion and contraction. The design of the helical spring allows it to effectively absorb impact energy through its own elastic deformation when subjected to tension or compression. A fixing plate 402 is fixedly connected to the end of the elastic element 401 away from the crash barrier body 3. The fixing plate 402 is made of steel plate of appropriate thickness, which has sufficient strength to fix the elastic element 401 and withstand the impact force. Its outer surface is fixedly connected to the outer surface of the protected object, thereby transferring part of the impact force to the protected object and realizing the dispersion of force.

[0028] Please see Figure 4 As shown, an elastic element 403 is fixedly connected to the outer surface of the fixing plate 402. The elastic element 403 is an elastic washer made of rubber. Rubber has good elasticity and damping characteristics. The elastic element 403 is located inside the elastic element 401. When the elastic element 401 is compressed to a certain extent under impact, the elastic element 403 begins to function. It can further buffer the remaining impact force, and at the same time, it uses the damping characteristics of rubber to consume some impact energy, reduce the impact force on the protected object, and also play a certain role in sealing and corrosion prevention, protecting the connection between the fixing plate 402 and the protected object.

[0029] Please see Figure 5 As shown, the limiting frame 2 is equipped with a second buffer assembly 5 inside. The second buffer assembly 5 includes a limiting rod 501 fixedly connected to the inner wall of the limiting frame 2. The limiting rod 501 is made of stainless steel, which has good corrosion resistance and high strength, and can be used for a long time in humid or harsh environments without rusting or deformation. The limiting rod 501 is cylindrical, and rubber pad 1 502 and rubber pad 2 503 are fixedly connected to its outer surface. Both rubber pad 1 502 and rubber pad 2 503 are made of natural rubber, which has excellent elasticity and buffering performance. When the anti-collision plate body 3 completes the impact and begins to reset, rubber pad 1 502 can buffer the impact force of the slider 504 during the reset process, avoiding the reverse force generated during reset from damaging the anti-collision plate body 3 and related structures, and ensuring the stability of the entire structure. Rubber pad 2 503 buffers the elastic element 3 506 when the elastic element 3 506 contracts to its limit position, preventing the elastic element 3 506 from being damaged due to excessive contraction, extending its service life, and ensuring that the second buffer assembly 5 can continuously and stably perform its buffering function.

[0030] Please see Figure 5As shown, a slider 504 is fixedly connected to the outer surface of the limiting rod 501. The slider 504 is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction and good self-lubricating properties, making the slider 504 slide more smoothly on the limiting rod 501 and reducing the impact of friction on the buffering effect. A bearing plate 505 is fixedly connected to the outer surface of the slider 504. The bearing plate 505 is a rectangular metal plate made of high-strength alloy steel, which has high strength and rigidity. The outer surface of the bearing plate 505 is in contact with the outer surface of the anti-collision plate body 3. When the anti-collision plate body 3 is impacted and slides, the bearing plate 505 moves on the limiting rod 501 through the slider 504, transferring part of the impact force to the elastic element 3 506, thus achieving effective transmission and dispersion of the impact force.

[0031] Please see Figure 4 As shown, an elastic element 3 506 is sleeved on the outer surface of the limiting rod 501. The elastic element 3 506 is a compression spring, also made of spring steel, and has good elastic properties. One end of the elastic element 3 506 is fixedly connected to the outer surface of the slider 504, and the end of the elastic element 3 506 away from the slider 504 is fixedly connected to the outer surface of the rubber pad 2 503. When the anti-collision plate body 3 is impacted, the elastic element 3 506 is compressed between the slider 504 and the rubber pad 2 503, and absorbs a large amount of impact energy through its own elastic deformation. It is an important energy absorption component in the buffer assembly 2 5. Working together with other components, it improves the impact resistance and protection effect of the anti-collision plate.

[0032] In use, when an object impacts the anti-collision plate body 3, the impact force first acts on the anti-collision plate body 3. Since the anti-collision plate body 3 is slidably connected to the limiting frame 2, it will slide along the limiting frame 2 under the impact force. At this time, the second buffer component 5 begins to function. Simultaneously, the slider 504 moves with the movement of the anti-collision plate body 3, transferring part of the impact force to the third elastic element 506 through the bearing plate 505 and the slider 504. The third elastic element 506 undergoes elastic deformation under the impact force, absorbing a large amount of impact energy. The second rubber pad 503 plays an important protective role. When the third elastic element 506 contracts to its limit position under the strong impact force, the second rubber pad 503 can intervene in time to buffer the third elastic element 506, preventing damage due to excessive contraction, extending its service life, and ensuring that the second buffer component 5 continuously and stably performs its buffering function. When the anti-collision plate body 3 completes the impact and begins to reset, the first rubber pad 502 again functions to further buffer the impact force. During the reset process, the impact force of the slider 504 is buffered to avoid damage to the anti-collision plate body 3 and related structures caused by the reverse force generated during reset, thus ensuring the stability of the entire structure. In addition, the buffer component 4 also plays a role simultaneously. The elastic element 401 connects the anti-collision plate body 3 and the fixed plate 402. During the movement of the anti-collision plate body 3, the elastic element 401 is stretched or compressed, and further absorbs the impact energy by its own elastic deformation. When the elastic element 401 is compressed to a certain state, the end of the elastic element 403 away from the fixed plate 402 comes into contact with the anti-collision plate body 3. It buffers the impact force again to a certain extent and disperses some of the force to the fixed structure such as the wall, reducing the impact force borne by the anti-collision plate body 3. Through the coordinated cooperation of various components in the buffer component 4 and the buffer component 5, the impact force is absorbed and dispersed in a multi-level and multi-stage manner from different stages and levels, thereby effectively protecting the protected object from damage and greatly improving the impact resistance and protection effect of the anti-collision plate.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
