Abstract
A damper of furniture comprises a piston and a damp plate which are sequentially connected in a cylinder. One end of a piston rod extends into the cylinder and is connected with the piston after penetrating through the damp plate; the piston is provided with more than one flow-passing hole, or the outer side of the piston is provided with more than one first flow-passing groove; one side of the damp plate, opposite to the piston, is provided with an annular step; a certain oil-passing gap is retained between the piston and the inner wall of the cylinder and between the damp plate and the inner wall of the cylinder; one end of the piston rod, connected with the piston, is in a T shape and is connected with the piston as a whole. The damper can be arranged in a pivoted arm, rotates flexibly and can not easily loose. When a door is closed, the damper has strong impact resistance, can effectively slow down the closing speed and reduce the collision sound generated by closing the door, andthe door is opened without any influence. The invention has simple and reasonable structure, low manufacture cost and long service life.
