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.
