DETAILED DESCRIPTION
[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] Please refer to Figure 1 The buffer protection structure of the metal guardrail in the embodiment comprises two columns 1, the top and the bottom between the opposite sides of the two columns 1 are fixed with connecting plates 2, the opposite sides between the upper and lower connecting plates 2 are fixed with vertical plates 3, the front and rear sides of the connecting plates 2 are provided with buffer mechanisms 4 for buffering, and the front and rear sides of the vertical plates 3 are provided with prompting mechanisms 5 for prompting passing vehicles.
[0023] The width of the connecting plate 2 is less than the width of the column 1, and the number of the vertical plates 3 is not less than two and is evenly distributed between the opposite sides of the upper and lower connecting plates 2.
[0024] Please refer to Figures 2 to 3In order to prevent direct impact on the connecting plate 2, the buffering mechanism 4 in the embodiment comprises stress plates 401 arranged on the front and rear sides of the connecting plate 2, and a buffer plate 402 is fixed to the side opposite to the stress plate 401 on the front and rear sides. When the metal guardrail is impacted by external force, the buffer plate 402 and the stress plate 401 will be first extruded, and the buffer plate 402 can absorb part of the external force. After the stress plate 401 is stressed, it will move towards the side close to the connecting plate 2. The middle part of the front and rear sides of the connecting plate 2 is provided with a fixing groove 403, and the middle part between the left and right side walls of the inner cavity of the fixing groove 403 is fixed with a limiting rod 404. The left and right ends of the outer surface of the limiting rod 404 are slidably connected with a sliding block 405, and the side opposite to the stress plate 401 of the sliding block 405 is hingedly connected through a hinge seat and a hinge rod. The side opposite to the other sliding block 405 is fixed with a driving plate 406, and the top and bottom between the driving plate 406 and the fixing groove 403 are fixed with a first spring buffer rod 407. The movement of the stress plate 401 can drive the sliding block 405 to move away from each other on the outer surface of the limiting rod 404 through the hinge rod and the hinge seat. The movement of the sliding block 405 drives the driving plate 406 to move, and the movement of the driving plate 406 can extrude the first spring buffer rod 407 to shorten it, so that the first spring buffer rod 407 can absorb the pressure. The left and right sides between the side opposite to the connecting plate 2 of the stress plate 401 are fixed with a second spring buffer rod 408. When the stress plate 401 moves towards the side close to the connecting plate 2, the second spring buffer rod 408 will be pressed.
[0025] Wherein, the size of the stress plate 401 is smaller than the size of the connecting plate 2, the buffer plate 402 is a rubber plate, and the two sliding blocks 405 are symmetrically distributed on the left and right sides of the vertical central axis of the limiting rod 404. The driving plate 406 is slidably connected with the limiting rod 404.
[0026] In the embodiment, the number of the second spring buffer rod 408 is not less than two, and the not less than two second spring buffer rods 408 are evenly distributed on the left and right sides between the side opposite to the connecting plate 2 of the stress plate 401.
[0027] It can be understood that the energy of the impact is absorbed by the deformation of the first spring buffer rod 407 and the second spring buffer rod 408, and the direct impact of the stress plate 401 on the connecting plate 2 is reduced.
[0028] Please refer to Figure 4In order to avoid hitting the metal guardrail, the prompt mechanism 5 in this embodiment includes reflective strips 501 fixed on the front and rear sides of the vertical plate 3. The reflective strips 501 can warn the driver when the light is irradiated on its surface, avoiding hitting the metal guardrail and protecting the service life of the metal guardrail. A support frame 502 is fixed on the upper surface of the column 1, and solar panels 503 are fixed on the top of the left and right sides of the support frame 502. A lighting lamp 504 is fixed on the upper surface of the column 1. The solar panel 503 can absorb sunlight and convert solar energy into electrical energy, so that it can be used to provide lighting for pedestrians and vehicles when the lighting lamp 504 is at night.
[0029] The inner cavity of the support frame 502 is larger than the inner cavity of the lighting lamp 504 , and a transparent rainproof film is attached to the outer surface of the lighting lamp 504 .
[0030] The working principle of the above embodiment is:
[0031] (1) When the metal guardrail is hit by an external force, the buffer plate 402 and the force-bearing plate 401 will be squeezed first. The buffer plate 402 is provided to absorb part of the external force. After the force-bearing plate 401 is subjected to force, it will move to the side close to the connecting plate 2, and then the slider 405 can be pushed to move in opposite directions on the outer surface of the limit rod 404 through the hinge rod and the hinge seat. The movement of the slider 405 drives the driving plate 406 to move. The movement of the driving plate 406 can squeeze the first spring buffer rod 407 to shorten it, and then the first spring buffer rod 407 can absorb the pressure. When the force-bearing plate 401 moves to the side close to the connecting plate 2, pressure will be generated on the second spring buffer rod 408. The deformation of the first spring buffer rod 407 and the second spring buffer rod 408 absorbs the energy of the impact, thereby reducing the direct impact of the force-bearing plate 401 on the connecting plate 2.
[0032] (2) When a car is driving at night, the reflective strip 501 can warn the driver when light shines on its surface, avoiding collision with the metal guardrail. The solar panel 503 can absorb sunlight and convert solar energy into electrical energy, which can be used to provide lighting for pedestrians and vehicles at night by the lighting lamp 504.
[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
