The invention provides a multi-section buffer and relates to the technical field of buffers, the multi-section buffer is provided with a first buffer assembly, second buffer assemblies and third buffer assemblies, the first buffer assembly is movably connected with the second buffer assemblies in an inserted mode, and the second buffer assemblies are movably connected with the third buffer assemblies in an inserted mode; the first buffering assembly comprises a bottom cylinder body, the lower end of the bottom cylinder body is connected with a bottom plate, an oil cylinder through pipe is arranged on the side of the bottom cylinder body and externally connected with an oil storage tank, an assembly hole is connected with a first oil barrel, and the first oil barrel comprises a first oil passing hole groove. The second buffering assembly comprises a second oil cylinder, and a second oil passing hole groove is formed in the second oil cylinder. The third buffering assembly comprises a third oil cylinder, and a third oil passing hole groove is formed in the third oil cylinder. The buffer has the beneficial effects that the oil passing hole grooves are formed in the side walls of the oil cylinders which are connected in an inserted mode, buffering force is gradually increased during compression, in addition, the height of the buffer is only the height of the first buffering assembly after the buffer is compressed, and a large buffering stroke is achieved.

    本发明提供一种多节缓冲器,涉及缓冲器技术领域,具有第一缓冲组件、第二缓冲组件以及第三缓冲组件,所述第一缓冲组件活动插接有若干第二缓冲组件,第二缓冲组件活动插接有第三缓冲组件;所述第一缓冲组件包括底缸体,底缸体下端连接底板,底缸体侧方设置有油缸通管,油缸通管外接储油箱,装配孔连接第一油筒,第一油筒包括第一过油孔槽;所述第二缓冲组件包括第二油筒,第二油筒上设置有第二过油孔槽;所述第三缓冲组件包括第三油筒,第三油筒上设置有第三过油孔槽。本发明的有益之处是,在互相插接的油筒的侧壁设置过油孔槽,在压缩时实现了缓冲力逐渐变大,另外,缓冲器压缩之后的高度只有第一缓冲组件的高度,实现了较大的缓冲行程。
