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 1-2 In this embodiment, a road traffic safety facility construction anti-collision guardrail includes at least two bases 1, a bracket 4 is fixed on the top of the base 1, a fixing plate 5 is fixed between the opposite sides of the two brackets 4, an anti-collision mechanism 2 is provided on the fixing plate 5, and a connecting component 3 is provided on the fixing plate 5.

[0021] In this embodiment, the anti-collision mechanism 2 and the connecting assembly 3 cooperate to enable the anti-collision guardrail to weaken the impact force of the object and reduce the impact damage itself when it is hit, thereby improving the anti-collision performance.

[0022] See also Figure 2-3 In order to improve the anti-collision performance of the anti-collision guardrail, the anti-collision mechanism 2 in this embodiment includes two mounting seats 201 fixed to the left and right ends of the inner rear side wall of the fixed plate 5, a fixing rod 202 is fixed between the opposite sides of the two mounting seats 201, and two sliders 203 are slidably connected to the outer surface of the fixing rod 202, and a first spring 204 is fixed between the opposite sides of the two sliders 203, and a connecting rod 205 is hinged at the front end of the slider 203, and an anti-collision baffle 206 is hinged at the front end of the two connecting rods 205, and a plurality of reflective strips are fixed on the front of the anti-collision baffle 206, and telescopic rods 207 are fixed on the left and right ends of the back of the anti-collision baffle 206, and the backs of the two telescopic rods 207 are respectively fixed to the left and right sides of the inner rear side wall of the fixed plate 5, and a second spring 208 is fixed on the outer surface of the telescopic rod 207. The anti-collision mechanism 2 also includes a slide groove 209 opened on the inner rear side wall of the fixed plate 5.

[0023] In this embodiment, the movement of the anti-collision baffle 206 drives the connecting rod 205 to move, the movement of the slider 203 generates kinetic energy, the first spring 204 generates elastic force to form resistance, and at the same time, multiple second springs 208 shrink to generate elastic force, forming resistance to the movement of the anti-collision baffle 206, further playing a buffering role, and buffering and unloading the impact force.

[0024] It should be noted that the slide groove 209 and the slider 203 are slidably connected, and the cross-sections of the slider 203 and the slide groove 209 are convex, which makes the slide groove 209 more stable during movement. The outer surface of the fixed rod 202 is socketed with the first spring 204 to provide support for the movement of the first spring 204.

[0025] See also Figure 2 In order to improve the anti-collision performance of the anti-collision guardrail, the connecting component 3 in this embodiment includes connecting blocks 301 fixed to the left and right ends of the back of the anti-collision baffle 206, and guide blocks 302 are fixed on the opposite sides of the two connecting blocks 301. The connecting component 3 also includes guide grooves 303 opened at the left and right ends of the fixing plate 5, and the guide grooves 303 and the guide blocks 302 are slidably connected.

[0026] In this embodiment, the movement of the anti-collision baffle 206 drives the connecting rod 205 and the connecting block 301 to move, and the guide groove 303 moves along the guide block 302 to provide guidance for the movement of the anti-collision baffle 206 .

[0027] The working principle of the above embodiment is:

[0028] When the anti-collision baffle 206 is impacted by the outside world, the movement of the anti-collision baffle 206 drives the connecting rod 205 and the connecting block 301 to move. At this time, the guide groove 303 moves along the guide block 302 to provide a certain guide for the movement of the anti-collision baffle 206. The movement of the connecting rod 205 prompts the slider 203 to move stably along the slide groove 209 to generate kinetic energy. At the same time, the first spring 204 will also generate elastic force to form resistance to prevent the slider 203 from moving, which can play a certain buffering role. At the same time, the elastic force generated by the compression of multiple second springs 208 can also form resistance to the movement of the anti-collision baffle 206, further playing a buffering role, and cooperating with each other to offset the external force to the greatest extent, buffer the impact force, improve the anti-collision performance, and at the same time extend the service life of the anti-collision guardrail to the greatest extent.
