Description

Technical Field

[0001] This utility model relates to the field of anti-collision guardrail technology, and in particular to an anti-collision cargo box guardrail. Background Technology

[0002] In today's logistics, transportation, and warehousing sectors, the safety and protection of cargo containers are of paramount importance. With the booming development of the freight industry, cargo containers face numerous collision risks during transportation, handling, and storage. Whether it's accidental collisions between vehicles during road transport or scraping between cargo containers and handling equipment such as forklifts in warehouses and logistics centers, these incidents can all lead to damage to the containers, resulting in damage to the goods and economic losses.

[0003] Existing cargo box guardrails only have a simple blocking function. When faced with a large impact, they cannot effectively absorb and disperse energy. Traditional rigid guardrails are prone to deformation and breakage after being hit, making it difficult to provide continuous protection. Moreover, they are not good at protecting the main body of the cargo box and cannot prevent the impact force from being directly transmitted to the cargo box, resulting in problems such as dents and damage to the cargo box.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a crash-resistant cargo box guardrail, including a base plate 1, a support column 2 fixedly connected to the surface of the base plate 1, two fixed rods 3 fixedly connected to the surface of the support column 2, a sliding frame 5 slidably connected to the surface of the two fixed rods 3, a push rod 6 rotatably connected to one side of the sliding frame 5, a fixed seat 7 rotatably connected to one end of the push rod 6, and a crash-resistant frame 8 fixedly connected to one side of the fixed seat 7. When the crash-resistant frame 8 is subjected to an external collision force, the force is transmitted to the push rod 6 through the fixed seat 7. Due to the rotatable connection characteristics of the push rod 6 with the sliding frame 5 and the fixed seat 7... The collision force can be converted into a sliding driving force for the sliding frame 5 along the fixed rod 3, causing the sliding frame 5 to displace on the surface of the fixed rod 3. During this process, the sliding action of the sliding frame 5 achieves the initial transmission and dispersion of the collision force, avoiding the force from acting directly on the main body of the distribution cabinet. At the same time, the support column 2, as the load-bearing foundation of the entire structure, works with the fixed rod 3 to provide a stable sliding trajectory for the sliding frame 5, ensuring that the force transmission path is controllable. The base plate 1, through its fixed connection with the support column 2, stably supports the overall structure, ultimately protecting the cargo box and reducing the direct impact of external collisions on the cabinet.

[0025] Reference Figure 1 and Figure 2 As shown in this embodiment: the number of sliding frames 5 is set to two sets, the two sets of sliding frames 5 are symmetrically distributed, and the surface of the sliding frame 5 is provided with two sets of springs 4. The two sets of springs 4 are symmetrically arranged and located at both ends of the sliding frame 5. A damping sleeve 12 is fixedly connected to the side of the sliding frame 5 away from the push rod 6. A damping rod 13 is slidably connected to the surface of the damping sleeve 12. The two ends of the damping rod 13 are fixedly connected to the surface of the support column 2. When the anti-collision frame 8 is impacted by an external force, the two sets of symmetrically distributed sliding frames 5 can slide synchronously along the fixed rod 3 to ensure uniform force distribution and avoid structural distortion due to unilateral force. The symmetrical springs 4 at both ends of the sliding frame 5 generate elastic deformation when the sliding frame 5 is displaced, converting kinetic energy into elastic potential energy to achieve initial buffering. At the same time, the sliding friction between the damping sleeve 12 and the damping rod 13 forms a damping force, suppressing the rebound oscillation of the spring 4, making the buffering process smoother and irreversible, effectively preventing secondary impact damage to the cargo box, and enhancing the impact resistance of the guardrail.

[0026] Reference Figure 1 and Figure 3 As shown, specifically, a reinforcing plate 9 is fixedly connected between the two sets of anti-collision frames 8, and a reflector 10 is provided on the surface of the anti-collision frame 8. A buffer plate 11 is provided on the inner wall of the anti-collision frame 8. The buffer plate 11 is in a continuous "Z" shape. A reinforcing rib 14 is provided at the connection between the base plate 1 and the support plate, and a fixing bolt 15 is provided at each of the four corners of the base plate 1. The reinforcing plate 9 between the two sets of anti-collision frames 8 enhances the overall rigidity of the anti-collision frame 8, preventing the anti-collision frame 8 from deforming or breaking during a collision, and improving the structural strength of the anti-collision component. The reflector 10 on the surface of the anti-collision frame 8 can reflect light in low-light environments, playing a clear warning role and reducing the risk of collision due to poor visibility. At the same time, the "Z" shape on the inner wall of the anti-collision frame 8... The shaped buffer plate 11, through its continuous bending structure design, can disperse the impact force layer by layer through its own deformation when it is hit, further reducing the impact of the collision on the cargo box. The reinforcing ribs 14 at the connection between the bottom plate 1 and the support plate effectively enhance the load-bearing capacity of the connection between the two, preventing loosening or breakage during long-term use. The fixing bolts 15 at the four corners of the bottom plate 1 can firmly fix the entire guardrail structure to the mounting surface, preventing the guardrail from shifting during collisions or vibrations, and ensuring the stable performance of the protective function.

[0027] Working principle: First, the bottom plate 1 is fixed to the outside of the cargo box by the fixing bolt 15. When the external collision force acts on the anti-collision frame 8, the force is first transmitted through the surface of the anti-collision frame 8. The "Z"-shaped buffer plate 11 on the inner wall initially disperses the impact force through deformation. Then, the force is transmitted to the push rod 6 through the fixing seat 7. The push rod 6, with the rotational connection characteristics with the sliding frame 5 and the fixing seat 7, converts the force into the sliding driving force of the sliding frame 5 along the fixing rod 3, so that the two sets of symmetrically distributed sliding frames 5 slide synchronously along the fixing rod 3. During this process, the symmetrical springs 4 at both ends of the sliding frame 5 undergo elastic deformation due to the displacement of the sliding frame 5, converting kinetic energy into elastic potential energy to achieve the initial buffer. At the same time, the damping sleeve 12 on one side of the sliding frame 5 slides along the damping rod 13 to generate damping force, suppressing the rebound oscillation of the spring 4 to avoid secondary impact. The reinforcing plate 9 between the two sets of anti-collision frames 8 and the reinforcing rib 14 at the connection between the bottom plate 1 and the support plate respectively enhance the rigidity of the anti-collision frame 8 and the overall structure. The reflective plate 10 on the surface of the anti-collision frame 8 reduces the risk of collision through reflection warning.
