The buffer comprises a hydraulic buffer tank, an adjusting structure is arranged on the side of the hydraulic buffer tank, the adjusting structure comprises an outer barrel, and an oil guide pipe is connected between the bottom of the outer barrel and the hydraulic buffer tank; the sealing piston is arranged in an inner cavity of the outer barrel, and the top end of the sealing piston is fixedly connected with a T-shaped connecting rod; the nut seat is fixedly connected to the top end of the outer cylinder, the inner side of the nut seat is in threaded connection with a threaded rod, and a limiting sliding groove is formed in the bottom end of the threaded rod; and the second pressure spring is arranged outside the T-shaped connecting rod in a sleeving manner. The outer cylinder is arranged on the outer side of the hydraulic buffer tank and matched with a sealing piston, a T-shaped connecting rod and a second compressed spring on the outer cylinder to achieve the auxiliary buffer effect, meanwhile, a nut seat and a threaded rod are arranged on the outer cylinder, and a limiting sliding groove matched with the T-shaped connecting rod is formed in the bottom end of a matched thread; the lifting height of the sealing piston can be limited, so that the buffering grade is adjusted, and the sealing piston can meet the use requirement.

    本发明公开了缓冲等级可调节的缓冲器,包括液压缓冲罐,液压缓冲罐的边侧设置有调节结构,调节结构包括:外筒体,外筒体底部与液压缓冲罐之间连接有导油管;密封活塞,其设置于外筒体内腔,密封活塞顶端固定连接有T形连杆;螺母座,其固定连接于外筒体顶端,螺母座内侧螺纹连接有螺纹杆,螺纹杆的底端开设有限位滑槽;第二压簧,其套设于T形连杆外部。本发明通过液压缓冲罐外侧设置的外筒体,再配合外筒体上密封活塞、T形连杆和第二压簧可起到辅助缓冲的作用,同时外筒体上螺母座和螺纹杆的设置,在配合螺纹底端开设的与T形连杆相匹配的限位滑槽,能够实现对密封活塞上升高度进行限定,从而实现缓冲等级的调节,使其可满足使用需求。
