DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a road traffic deceleration and anti-collision guardrail device, including a first upright pole 1 and a second upright pole 2, two horizontal bars 3 are fixedly installed on the opposite sides of the first upright pole 1 and the second upright pole 2, a plurality of vertical bars 15 are fixedly installed on the opposite sides of the two horizontal bars 3, two circular through holes 16 are provided inside the plurality of vertical bars 15, a moving rod 17 is slidably installed inside the circular through holes 16, spring pressure plates 19 are fixedly installed on both ends of the moving rod 17, and the end of the spring pressure plate 19 away from the moving rod 17 is An anti-collision column 8 is fixedly installed, and buffer springs 18 are sleeved on the outer sides of both ends of the moving rod 17. One end of the buffer spring 18 is fixedly connected to the end of the spring pressure plate 19 away from the anti-collision column 8, and the other end of the buffer spring 18 is fixedly connected to the outer side of the vertical rail 15. A rubber protective pad 7 is fixedly installed on the side of the anti-collision column 8 away from the spring pressure plate 19, and two fluorescent strips 11 are symmetrically installed on the side of the rubber protective pad 7 away from the anti-collision column 8. A support seat 13 is fixedly installed at the bottom of the first vertical pole 1 and the second vertical pole 2.

[0021] The working principle of the above technical solution is as follows: when an external object hits the outer side of the guardrail, the object first contacts the rubber protective pad 7 on the outer side of the anti-collision column 8. The rubber protective pad 7 can prevent the external object from directly hitting the surface of the horizontal rail 3 and the vertical rail 15, thereby playing an anti-collision effect. In addition, under the impact of external force, the anti-collision column 8 will push the moving rod 17 to move inside the circular through hole 16 inside the vertical rail 15 through the spring pressure plate 19, and in the process of the movement of the moving rod 17, the spring pressure plate 19 on one side of the rubber protective pad 7 that is hit will squeeze the buffer spring 18, thereby playing a switching role, and the spring pressure plate 19 on the other side of the rubber protective pad 7 will pull the buffer spring 18, so that the buffer springs 18 on both sides of the vertical rail 15 are deformed, generating buffer elastic force, reducing the impact force of the object on the guardrail as a whole, realizing protection of the guardrail, and ensuring the normal use of the guardrail.

[0022] In another embodiment, Figure 1-Figure 3As shown, two rotating rods 14 are fixedly installed on both sides of the first vertical pole 1 and the second vertical pole 2, and the rotating rods 14 are rotatably installed on the opposite sides of the rotating rods 14, and the outer sides of the rotating rods 14 are fixedly installed with side anti-collision plates 6, and the top and bottom of one side of the side anti-collision plates 6 are fixedly installed with arc-shaped airbags 5, the side of the arc-shaped airbag 5 away from the side anti-collision plate 6 is fixedly connected to one side of the crossbar 3, and the side of the side anti-collision plate 6 away from the arc-shaped airbag 5 is fixedly installed with a rubber protective pad 2 10.

[0023] When an external object hits the outer side of the side impact plate 6, the impact force will cause the rotating rod 14 to rotate on the inner side of the ear plate 12, so that the side impact plate 6 squeezes the arc-shaped airbag 5. The arc-shaped airbag 5 deforms to buffer the impact force, thereby improving the overall anti-collision performance of the guardrail.

[0024] In another embodiment, Figure 1-Figure 2 As shown, two connecting slots 4 are symmetrically provided on the side of the first upright pole 1 away from the horizontal bar 3, and two connecting posts 9 are symmetrically fixedly installed on the side of the second upright pole 2 away from the horizontal bar 3. The specifications of the outer diameters of the two connecting posts 9 match the specifications of the inner diameters of the two connecting slots 4, and the positions of the two connecting posts 9 correspond to the positions of the two connecting slots 4 respectively.

[0025] The guardrails can be assembled by means of the provided connection slots 4 and connection posts 9, thereby extending the length of the guardrails and improving the overall applicability of the guardrails.

[0026] Working principle: The guardrails can be assembled by setting the connecting slot 4 and the connecting column 9 to extend the length of the guardrail. When an external object hits the outside of the guardrail, the object first contacts the rubber protective pad 7 on the outside of the anti-collision column 8. The rubber protective pad 7 can prevent the external object from directly hitting the surface of the horizontal rail 3 and the vertical rail 15, thereby achieving an anti-collision effect. In addition, under the impact of external force, the anti-collision column 8 will push the moving rod 17 to move inside the circular through hole 16 inside the vertical rail 15 through the spring pressure plate 19, and in the process of the moving rod 17 moving, the spring pressure plate 19 on the side of the rubber protective pad 7 that is hit will The buffer spring 18 is squeezed to play a switching role, and the spring pressure plate 19 on the other side of the rubber protective pad 7 will pull the buffer spring 18, so that the buffer springs 18 on both sides of the vertical rail 15 are deformed, generating a buffer elastic force, reducing the impact force of the object on the guardrail as a whole, thereby protecting the guardrail and ensuring the normal use of the guardrail. When an external object hits the outer side of the side anti-collision plate 6, the impact force will prompt the rotating rod 14 to rotate on the inner side of the ear plate 12, so that the side anti-collision plate 6 squeezes the arc airbag 5, and the arc airbag 5 is deformed to buffer the impact force, thereby improving the overall anti-collision performance of the guardrail.
