Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is correspondingly changed.

In the present application, unless explicitly specified and limited otherwise, the terms "coupled," "secured," and the like are to be construed broadly, and for example, "secured" may be either permanently attached or removably attached, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In addition, if there is a description of "first", "second", etc. in the embodiments of the present application, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and/or" as it appears throughout includes three parallel schemes, for example "A and/or B", including the A scheme, or the B scheme, or the scheme where A and B are satisfied simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be regarded as not exist and not within the protection scope of the present application.

Referring to fig. 1 to 3, the embodiment of the application provides a highway buffering crash barrier, including the elasticity railing, the elasticity railing includes entablature 300, underbeam 400 and direction rotary drum 100, wherein, entablature 300 and underbeam 400 centre gripping respectively in the upper and lower both sides of direction rotary drum 100, and direction rotary drum 100 can rotate between entablature 300 and underbeam 400, then when the vehicle strikes the elasticity railing, the elasticity railing is with the help of direction rotary drum 100, change the vehicle direction of travel, the vehicle slides along a plurality of continuous direction rotary drum 100, the direction of travel of orderly adjustment vehicle is until with guardrail or highway road surface syntropy, prevent that the vehicle from dashing out the road surface.

In this embodiment, the guiding drum 100 includes an upper end cover 101 and a lower end cover 102, a plurality of stress columns 103 are circumferentially arrayed between the upper end cover 101 and the lower end cover 102, two ends of the stress columns 103 are integrally formed with the upper end cover 101 and the lower end cover 102 respectively, a central column 105 is integrally formed between the upper end cover 101 and the central position of the lower end cover 102, an elastic plate 104 is arranged between the adjacent stress columns 103 and between the stress columns 103 and the central column 105, the guiding drum 100 is divided into a plurality of buffering energy releasing cavities by the elastic plate 104, and a plurality of coils of coiled spring pieces 200 are arranged in each buffering energy releasing cavity.
