The invention relates to a damping buffer device, which comprises a pipe body, an end cover, a pull rod, a piston group and a spacer, wherein one end of the pipe body is an open end; one end, which is far away from the open end, of the pipe body is the bottom part of the pipe body; the end cover is arranged at the open end of the pipe body; the end cover and the pipe body are hermetically fixed; the spacer is arranged in the open end the pipe body; damping liquid is arranged between the bottom part of the pipe body and the spacer; after penetrating through the end cover and the spacer, one end of the pull rod extends into the pipe body; one end, which is located in the pipe body, of the pull rod is provided with the piston group; at least one flow channel arranged along the axial direction of the pipe body is formed in the inner wall of the pipe body; the at least one flow channel is gradually reduced and then gradually increased in cross sectional area from one end to other end. According to the damping buffer device disclosed by the invention, buffer resistance can be effectively regulated in a closing process of sliding members of furniture, so the smoothness of the sliding members in the closing process can be ensured; the damping buffer device can also exert buffer action.
