[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1, please refer to Figures 1-4 An adjustable guardrail for complex terrain includes a post 1 and a guardrail body 2 that works with the post 1. The guardrail body 2 has a mounting base 3 on its side. Both sides of the post 1 have fasteners 4, which are used to insert into the outer surface of the mounting base 3. Both sides of the fasteners 4 have connection ports 401. A first fixing bolt 402 is inserted between the two connection ports 401 and is connected to the mounting base 3. The first fixing bolt 402 consists of a head and a threaded part. The diameter of the threaded part of the first fixing bolt 402 is smaller than the length and width of the connection port 401. After the threaded part of the first fixing bolt 402 is inserted into the connection port 401, because the diameter of the threaded part of the first fixing bolt 402 is smaller than the length and width of the connection port 401, the threaded part of the first fixing bolt 402 can be finely adjusted in the up, down, left, and right directions within the connection port 401. This facilitates the connection of the fasteners 4 and the mounting base 3, allowing the guardrail body 2 and the post 1 to tilt to meet the needs of complex terrain.

[0027] Fastener 4 is a U-shaped metal part with its opening facing the card holder 3.

[0028] Furthermore, the card holder 3 is provided with a connecting hole 301, and the connecting hole 301 allows the screw portion of the first fixing bolt 402 to pass through, so that after the fastener 4 is inserted into the card holder 3, the first fixing bolt 402 can fix the card holder 3 and the fastener 4 together.

[0029] Furthermore, the card holder 3 is welded to the side of the guardrail body 2, and the welded joints of the guardrail body 2 and the card holder 3 are coated with protective paint. The protective paint can be epoxy resin paint. The application of epoxy resin paint can reduce the corrosion of the welded joints of the guardrail body 2 and the card holder 3.

[0030] Furthermore, the outer surface of the guardrail body 2 is coated with reflective paint, specifically fluorescent reflective paint. Fluorescent reflective paint has reflective properties and reflects light at night to improve visibility.

[0031] Furthermore, a fastening nut 403 is threadedly connected to the end of the first fixing bolt 402 away from the head, and the heads of the fastening nut 403 and the first fixing bolt 402 are located on both sides of the fastener 4. The fastening nut 403 and the first fixing bolt 402 cooperate with each other to fix the fastener 4 and the card holder 3 together.

[0032] Furthermore, two washers 405 are provided on the threaded portion of the first fixing bolt 402, and the two washers 405 are respectively located between the fastener 4, the fastening nut 403 and the head of the first fixing bolt 402.

[0033] Example 2 further optimizes the adjustable guardrail for complex terrain provided in Example 1. Specifically, the fastener 4 is welded to the side of the post 1, and the welding method ensures a strong connection.

[0034] Example 3 further optimizes the adjustable guardrail for complex terrain provided in Example 1, specifically, as follows: Figure 4 As shown, the fastener 4 is provided with a through hole, and the column 1 is provided with a threaded hole. A second fixing bolt 404 is inserted into the through hole, and one end of the second fixing bolt 404 is threadedly connected to the threaded hole on the column 1. The fastener 4 is fixed to the column 1 by the second fixing bolt 404, which enables the fastener 4 to be detachably connected.

[0035] Example 4 further optimizes the adjustable guardrails for complex terrain provided in the above embodiments, such as... Figure 1 As shown, a cover is provided on the outer surface of the column 1. The cover is located below the fastener 4. The cover is a cover plate 102. The middle of the cover plate 102 has a hole that matches the cross-section of the column 1, and the outer surface of the column 1 passes through the hole. Since the column 1 is fixed by setting a pit on the road surface and then filling it with materials such as concrete or asphalt, the newly filled material has a color difference with the original material of the road surface, which is not aesthetically pleasing. Therefore, covering the newly filled material with the cover plate 102 can improve the overall aesthetics.
