Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, and in particular to a foldable temporary road safety buffer device. Background Technology

[0002] Highway collision buffer devices are specialized safety facilities installed around highway maintenance and construction areas or accident sites. They absorb collision energy through structural deformation and energy dissipation of buffer materials, reducing the impact of out-of-control vehicles on construction personnel, equipment, and road facilities, thereby mitigating the severity of collision accidents and ensuring on-site operational safety and traffic order.

[0003] For example, Chinese Patent Publication No. CN108755513B discloses a highway anti-collision device, which includes an anti-collision buffer unit, a connecting unit, and a column. The anti-collision buffer unit is located on the side close to the highway and is connected to the column through multiple connecting units. The anti-collision buffer unit consists of a pressure-reducing plate, a slider, a shock-absorbing spring, a base, a tension spring, screws, a buffer layer, and reflective strips. The pressure-reducing plate and the buffer layer are semi-circular rings, and straight sections are provided at the top and bottom of the pressure-reducing plate and the buffer layer. They are fixedly connected to the slider by screws. The base consists of a groove, a protruding part, and a limiting baffle.

[0004] In the event of an emergency on the highway, when an emergency rescue lane needs to be opened, guardrails placed between the motor vehicle lane and the non-motor vehicle lane can hinder the efficient conduct of rescue operations. When it is necessary to quickly move the injured to the interior of the rescue vehicle, the guardrails will block rescue personnel, making it impossible to transport the injured to medical institutions for treatment in time within the golden rescue period, causing the injured to miss the best treatment opportunity. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing guardrails placed between motor vehicle lanes and non-motor vehicle lanes prevent rescuers from quickly lifting the injured into rescue vehicles, thus delaying the best rescue time. Therefore, a foldable temporary road crash buffer device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foldable temporary highway anti-collision buffer device, comprising several connecting long rods and several foldable guardrail components. Positioning grooves are provided on both sides of the connecting long rods. The two ends of the foldable guardrail components are respectively movably engaged within the positioning grooves. A positioning plate is provided at the upper end of the connecting long rods. A positioning rod is movably inserted through one end of the positioning plate. A baffle is fixedly installed at one end of the positioning rod. A return spring is movably sleeved on the outer side of one end of the positioning rod. The return spring and one end of the positioning rod are located inside one end of the foldable guardrail component. A pull rod is fixedly connected to the other end of the positioning rod.

[0007] Preferably, the foldable guardrail assembly includes two hollow tubes and several anti-collision plates, with the two ends of the anti-collision plates being rotatably connected to each other via a round shaft, and one end of the return spring and the positioning rod being disposed inside the hollow tubes.

[0008] Preferably, a honeycomb aluminum anti-collision buffer layer is fixedly bonded to one side of the anti-collision plate.

[0009] Preferably, a positioning screw is fixedly installed at the top of the connecting rod, a groove is provided at the center of the positioning plate, one end of the positioning screw moves through the inside of the groove, and a positioning nut is threaded to the outside of one end of the positioning screw.

[0010] Preferably, the other end of the connecting rod is fixedly connected to a base.

[0011] Preferably, load-bearing blocks are fixedly installed at both ends of the base.

[0012] Preferably, the interior of the load-bearing block has a rounded rectangular groove.

[0013] Preferably, a handle is fixedly connected to one side of the hollow tube.

[0014] Preferably, a reflective warning strip is fixedly adhered to the outside of the connecting rod.

[0015] Preferably, a first limiting rod is fixedly installed inside a positioning groove, and a second limiting rod is fixedly connected to one side of the other end of the positioning plate. One end of the first limiting rod and the second limiting rod respectively movably penetrate the interior of a hollow tube.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by grasping the pull rod and lifting the positioning rod upward, the baffle at one end of the positioning rod compresses the return spring, causing the baffle to drive the return spring to slide out from the inside of the hollow tube. At this time, by grasping the handle, the hollow tube that is movable and locked inside the positioning groove is pulled out, thereby opening the connection between the foldable guardrail assembly and the connecting long rod, and pushing the foldable guardrail assembly to retract it to form an emergency exit, which makes it convenient for rescuers to push the injured to the ambulance from the exit, thus improving rescue efficiency.

[0018] 2. In this invention, when the foldable guardrail assembly is impacted, the honeycomb aluminum anti-collision buffer layer comes into contact with the impact force first, and the honeycomb core material undergoes gradual collapse and deformation. This deformation process disperses the concentrated impact force along the honeycomb structure, greatly reducing the impact force per unit area. Compared to ordinary materials, honeycomb aluminum can absorb energy over a wider area, preventing excessive concentration of impact force that could lead to localized damage to the anti-collision plate or other parts of the guardrail, thus significantly improving the overall impact resistance of the guardrail assembly.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a foldable temporary highway anti-collision buffer device, including several connecting rods 1 and several foldable guardrail components 2. Positioning grooves 11 are provided on both sides of the connecting rods 1. The two ends of the foldable guardrail components 2 are respectively movably engaged inside the positioning grooves 11. A positioning plate 12 is provided at the upper end of the connecting rods 1. A positioning rod 121 is movably inserted through one end of the positioning plate 12. A baffle 122 is fixedly installed at one end of the positioning rod 121. A return spring 123 is movably sleeved on the outer side of one end of the positioning rod 121. The return spring 123 and one end of the positioning rod 121 are located inside one end of the foldable guardrail component 2. A pull rod 124 is fixedly connected to the other end of the positioning rod 121. The foldable guardrail component 2 includes two hollow tubes 21 and several anti-collision plates 22. The two ends of the several anti-collision plates 22 are rotatably connected to each other via round shafts. The return spring 123 and the positioning rod... One end of 121 is located inside the hollow tube 21. A positioning screw 13 is fixedly installed at the top of the connecting rod 1. A groove 125 is opened at the center of the positioning plate 12. One end of the positioning screw 13 moves through the inside of the groove 125. A positioning nut 131 is threaded to the outside of one end of the positioning screw 13. A base 14 is fixedly connected to the other end of the connecting rod 1. A load block 141 is fixedly installed at both ends of the base 14. A rounded rectangular groove 142 is opened inside the load block 141. A handle 211 is fixedly connected to one side of the hollow tube 21. A reflective warning strip 15 is fixedly glued to the outside of the connecting rod 1. A first limiting rod 111 is fixedly installed inside a positioning groove 11. A second limiting rod 112 is fixedly connected to one side of the other end of the positioning plate 12. One end of the first limiting rod 111 and the second limiting rod 112 moves through the inside of a hollow tube 21.

[0028] The specific settings and functions of this embodiment are described below. When it is necessary to quickly open the connection between the foldable guardrail assembly 2 and the connecting rod 1, first grasp the pull rod 124 and lift the positioning rod 121 upwards. The baffle 122 at one end of the positioning rod 121 compresses the return spring 123, causing the baffle 122 to drive the return spring 123 to slide out from the inside of the hollow tube 21. At this time, grasp the handle 211 and pull out the hollow tube 21 that is movable and locked inside the positioning groove 11, thereby opening the connection between the foldable guardrail assembly 2 and the connecting rod 1, and pushing the foldable guardrail assembly 2 to retract and form an emergency exit, which makes it convenient for rescuers to push the injured to the ambulance from the exit, thus improving rescue efficiency.

[0029] When it is necessary to remove the foldable guardrail assembly 2, rotate to remove the positioning nut 131, and then remove the positioning plate 12. At this time, one end of the second limiting rod 112 slides out from the inside of the hollow tube 21, applying an upward pushing force to the foldable guardrail assembly 2, so that the hollow tubes 21 at both ends slide out from the inside of the positioning groove 11, thus completing the removal operation.

[0030] Example 2: Figure 1 - Figure 5 As shown, the foldable temporary highway anti-collision buffer device of this utility model includes several connecting rods 1 and several positioning grooves 11 on both sides of the connecting rods 1. The two ends of the foldable guardrail assembly 2 are respectively movably engaged in the interior of the positioning grooves 11. A positioning plate 12 is provided at the upper end of the connecting rods 1. A positioning rod 121 is movably passed through one end of the positioning plate 12. A baffle 122 is fixedly installed at one end of the positioning rod 121. A return spring 123 is movably sleeved on the outer side of one end of the positioning rod 121. The return spring 123 and one end of the positioning rod 121 are located inside one end of the foldable guardrail assembly 2. A pull rod 124 is fixedly connected to the other end of the positioning rod 121. The foldable guardrail assembly 2 includes two hollow tubes 21 and several anti-collision plates 22. The two ends of the several anti-collision plates 22 are rotatably connected to each other through a round shaft. The return spring 123 and one end of the positioning rod 121 are located inside the hollow tubes 21. A honeycomb aluminum anti-collision buffer layer is fixedly bonded to one side of the anti-collision plate 22.

[0031] The overall effect of this embodiment is that by fixing and bonding a honeycomb aluminum impact buffer layer to one side of the crash barrier 22, the unique hexagonal honeycomb structure of the honeycomb aluminum acts like countless tightly arranged energy absorption units. When the foldable guardrail assembly 2 is impacted, the honeycomb aluminum impact buffer layer is the first to come into contact with the impact force, and the honeycomb core material undergoes gradual collapse and deformation. This deformation process can disperse the concentrated impact force along the honeycomb structure, greatly reducing the magnitude of the impact force per unit area. Compared with ordinary materials, honeycomb aluminum can absorb energy over a wider area, avoiding excessive concentration of impact force that could lead to localized damage to the crash barrier 22 or other guardrail components, significantly improving the overall impact resistance of the guardrail assembly. The honeycomb aluminum material has a certain degree of flexibility and plasticity, which can well adapt to the folding and unfolding process of the foldable guardrail assembly 2. When the guardrail is folded, the honeycomb aluminum impact buffer layer will not break or lose its buffering performance due to bending, and can still maintain its structural integrity. When the guardrail is unfolded and used again, its protective performance is not affected, ensuring that the foldable guardrail can still reliably play its role in shock absorption after multiple folding and unfolding operations.

[0032] The method of use and working principle of this device: First, grasp the pull rod 124 and lift the positioning rod 121 upwards. The baffle 122 at one end of the positioning rod 121 compresses the return spring 123, causing the baffle 122 to drive the return spring 123 to slide out from the inside of the hollow tube 21. Then, grasp the handle 211 and pull out the hollow tube 21 that is movable and locked inside the positioning groove 11, thereby opening the connection between the foldable guardrail assembly 2 and the connecting long rod 1, and pushing the foldable guardrail assembly 2 to retract it to form an emergency exit.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
