Problems solved by technology

However, because the diameter of the torsion spring steel wire is very small, the contact portion between the support leg of the torsion spring and the part is very small, almost a point contact, so the pressure at the contact is strong, resulting in serious wear between the torsion spring and the part, affecting the torsion spring. even the life of the entire hinge

Abstract

The invention discloses a hinge for furniture. The hinge comprises a connecting arm and a movable cup seat, which are connected through a swing arm. A torsion spring at least generating opening and closing action force on the movable cup seat is arranged in the hinge. The hinge is characterized in that an anti-friction block is arranged between the torsion spring and an inner swing arm, and is in sliding connection with the inner swing arm in the opening and closing processes of the hinge; a fixing part is arranged on the anti-friction block; and a pin shaft is inserted into the fixing part, and is fixedly arranged on an outer swing arm or the inner swing arm. The anti-friction block is arranged between the torsion spring and the inner swing arm, and is limited and fixedly arranged on the outer swing arm and / or the inner swing arm through the fixing part; the anti-friction block contacts with a part in the hinge through a plane, so that the contact between the anti-friction block and the part of the hinge is linear contact or surface contact, the pressure of a contact part is greatly reduced, rigid friction between the torsion spring and the part of the hinge is reduced, abrasion is reduced, the service life of the product is prolonged, and the aim of smoothly and reliably opening and closing the hinge is also fulfilled.

Description

technical field [0001] The invention relates to a hinge, in particular to a hinge for furniture. Background technique [0002] Chinese Patent Document No. CN1873178 disclosed a hinge device on December 6, 2006, which has: an elongated first body installed on the furniture body; a cover-shaped second body installed on the door; the second body The first and second chain links rotatably connected to the first body; and the torsion spring, one end of the torsion spring pushes the spring receiving plate of the first chain link, thereby, the second body faces the first The main body rotates and applies force, one end of the torsion spring is disposed between the side wall of the first main body and the side wall of the second link, the gap between the spring receiving plate and the side wall of the first main body, and the gap between the spring receiving plate and the side wall of the second link. The gaps between the side walls of the second link are all smaller than the line ...
