[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 5The utility model provides a technical solution: a guardrail for highway construction, characterized in that it includes a bracket 1, one side of the bracket 1 is rotatably connected to the bracket 2 2 by a hinge, and the surfaces of the bracket 1 and the bracket 2 2 are fixedly connected to the protective plate 3, and the surfaces of the bracket 1 and the bracket 2 are provided with a hidden groove 4, the inner wall of the hidden groove 4 is rotatably connected to the rotating rod 5 by a rotating shaft, and the inner wall of the rotating rod 5 is slidably connected to the telescopic rod 6, and the end of the telescopic rod 6 is rotatably connected to the adjusting mechanism 7 by the rotating shaft; wherein the adjusting mechanism 7 includes a support plate 71, the interior of the support plate 71 is fixedly connected to the fixing rod 72, and the surface of the fixing rod 72 is slidably connected to the sliding seat 73, and the sliding seat 73 is rotatably connected to the end of the telescopic rod 6 by a rotating shaft. By rotating the rotating rod 5 inside the hidden groove 4, it can adjust the telescopic rod 6 inside the rotating rod 5, so as to make the end of the telescopic rod 6 contact the ground, thereby assisting in supporting the back of the bracket 1 and the bracket 2, and preventing the single support front from being easily tilted by impact.

[0025] according to Figure 3 It can be seen that the surface of the protective plate 3 is connected with a rubber belt 8, and the number of rubber belts 8 is set to be several. Under the setting of the rubber belt 8, when the surface of the hidden groove 4 is hit, part of the impact force can be absorbed by the rubber belt 8, thereby reducing the destructive force caused by the impact force.

[0026] according to Figure 4 It can be seen that the interior of the protective plate 3 is fixedly connected to a spring cylinder 9, and the end of the spring cylinder 9 is fixedly connected to a fixed plate, which is located on the back of the rubber belt 8. Under the setting of the spring cylinder 9, it can be supported by the fixed plate. Since the support plate 71 is located on the back of the rubber belt 8, when the surface of the rubber belt 8 is hit, part of the force can be transferred to the spring cylinder 9, and then the impact force can be slowed down for a second time through the spring cylinder 9, thereby reducing the impact force to a minimum for protection.

[0027] according to Figure 4 It can be seen that the rubber belt 8 is fixedly connected with a warning strip 10, which is made of fluorescent material. With the setting of the warning strip 10, it can serve as a warning at night and improve safety at night under the fluorescence.

[0028] according to Figure 5It can be seen that the surface of the rotating rod 5 is connected with a fixing bolt 11 through a thread, and an adjustment hole 12 is opened on the surface of the telescopic rod 6. The adjustment hole 12 is adapted to the size of the fixing bolt 11. The number of adjustment holes 12 is set to several, and the several adjustment holes 12 are arranged at equal distances along the surface of the telescopic rod 6. When the fixing bolt 11 threadedly connected to the surface of the rotating rod 5 is rotated, it is inserted into the inside of the adjustment hole 12, so that the rotating rod 5 and the telescopic rod 6 can be locked. When the adjustment holes 12 are set to several, when the telescopic rod 6 is adjusted, the fixing bolt 11 can be inserted into the inside of the nearest adjustment hole 12 to fix it at any length.

[0029] according to Figure 2 It can be seen that a buffer spring 74 is sleeved on the surface of the fixed rod 72, and the two ends of the buffer spring 74 are respectively fixed on the support plate 71 and the sliding seat 73. Under the action of the spring force of the buffer spring 74, the support plate 71 and the sliding seat 73 can be buffered, thereby providing three buffering protections again.

[0030] The working principle of the present invention is as follows: when in use, first, both bracket 1 and bracket 2 2 are installed on the road, and then the protective plate 3 can play a protective role between bracket 1 1 and bracket 2 2, and then the hidden groove 4 opened on the surface of bracket 1 1 and bracket 2 2 is set, so that the rotating rod 5 inside the hidden groove 4 can be rotated and displaced, and then the telescopic rod 6 is slid and adjusted inside the rotating rod 5, so that the adjusting mechanism 7 connected to the bottom of the telescopic rod 6 can be rotated to contact the ground, and then the bolt is passed through the adjusting mechanism 7 to fix it to the ground more firmly. When the adjusting mechanism 7 is working, when bracket 1 and bracket 2 2 are subjected to impact force, most of the force will be absorbed by the protective plate 3, and then the sliding seat 73 on the surface of the fixed rod 72 inside the support plate 71 is pushed by the telescopic rod 6 to displace, so that the impact force can be reduced again by the displacement difference, and then the force brought by the displacement can be absorbed under the spring force of the buffer spring 74.
