Abstract

The invention provides a furniture damper. The furniture damper comprises a piston rod and a cylinder body, wherein damping oil is placed in the cylinder body; a piston is slidably arranged in the cylinder body; one end of the piston rod extends out of the cylinder body, and the other end of the piston rod is connected with the piston in a matched mode and slidably stretches out and draws back onthe cylinder body through the piston; an annular oil passing groove is formed in the piston, and an axial oil passing groove is formed between the piston and the piston rod; one end of the annular oilpassing groove communicates with the axial oil passing groove, and an oil passing opening is formed in the other end of the annular oil passing groove; an annular soft piece and a reset oil passing groove are further arranged between the piston and the cylinder body; the annular soft piece moves between the piston and the cylinder body and is opened or sealed on the reset oil passing groove during moving; and the oil passing direction of the oil passing opening is basically consistent with the oil passing direction of the axial oil passing groove and / or the oil passing direction of the resetoil passing groove. Through the improvement of the structure, the furniture damper has the characteristics of being simple and reasonable in structure, excellent in performance, convenient to use, lowin manufacturing cost, easy to produce and implement, long in service life, good in damping effect, good in sealing performance and the like, and the practicability is high.

Description

technical field [0001] The invention relates to a furniture damper. Background technique [0002] Chinese Patent Document No. CN102287103A disclosed a furniture hinge structure on December 21, 2011, which includes a hinge cup seat arranged on the furniture door body, a base connected to the furniture body and a damper thereof. There is a damper, the bottom plate is provided with a connecting wing corresponding to the damper, the damper is arranged on the connecting wing, the connecting wing is provided with a positioning part, and the damper is provided with a sleeve that slides and fits with it, and the sleeve is positioned correspondingly The part is provided with a positioning matching part, or the damper is provided with a positioning matching part corresponding to the positioning part. It is said that a connecting wing is added to the base of the structure, and the connecting wing is connected with the damper or its sleeve, so that the external force generated when the...
