[0029] Example 2:

[0030] like Figures 1-4 As shown, a lightweight thin-walled guardrail with energy-absorbing and buffering function according to an embodiment of the present utility model is provided with a buffer component 3 on one side of the adjustment component 2. The buffer component 3 includes a plurality of connecting slots 1 opened on one side of the adjustment seat 201. The number of connecting slots 1 is four. The inner wall of the connecting slot 1 is connected to a buffer plate 1 301 through a rotating rod 2. One end of the buffer plate 1 301 is connected to a buffer plate 2 302 through a rotating rod 2. One end of the buffer plate 2 302 is connected to a buffer seat 303 through a rotating rod 2. A connecting slot 2 is opened on one side of the buffer plate 2 302 and the buffer plate 1 301. The inner wall of the connecting slot 2 is connected to a hydraulic buffer 304 through a rotating rod 3.

[0031] A mounting component 4 is connected to one side of the buffer assembly 3. The mounting component 4 includes a placement groove opened above the buffer seat 303. Multiple spring-loaded telescopic rods 2 5 are fixed on both sides of the inner wall of the placement groove. There are four spring-loaded telescopic rods 2 5.

The adjusting plate 202 and the spring-loaded telescopic rod 203 installed on one side of the inner wall of the adjusting groove ensure that the adjusting plate 202 can move in a specific direction, which facilitates the auxiliary restriction of the rack 204. The interaction between the rack 204 and the adjusting plate 202 can change the height of the thin-walled guardrail plate 402 and the thin-walled guardrail plate 403. Adjusting the rotating adjusting rod 6 causes one end of the adjusting rod 6 to restrict the rack 204 through the bearing-set limiting block 7, preventing the adjusting seat 201 from sliding. At the same time, the buffer plate 301, the buffer plate 302, and the buffer seat 303 are connected through the rotating rod 2 in the connecting groove, which can adjust the height of the buffer plate 301 and the buffer plate 403. The angle between the two 302 plates changes to adapt to different collision situations. A hydraulic buffer 304 is installed between the first buffer plate 301 and the second buffer plate 302 to absorb and dissipate collision energy, thereby reducing the impact force transmitted to the guardrail system. The first thin-walled guardrail plate 402 and the second thin-walled guardrail plate 403 can be installed and connected by the mounting sleeve 401 placed in the groove on the buffer seat 303. The mounting sleeve 401 is tightly connected to the mounting sleeve 401 by the fixing screw 404 to ensure the stability of the entire guardrail system. The two sides of the groove are also equipped with spring-loaded telescopic rods 5 to provide additional support and reset capability for the mounting sleeve 401, helping to disperse the force when an impact occurs. The guardrail post 1 is locked with the groove by a limiting cover 8 to further ensure the safety and stability of the guardrail post 1. At the same time, there are multiple mounting holes on the guardrail post 1, which can be used to firmly fix the guardrail to the ground or other supporting structures by mounting screws 9.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
