Abstract
The invention provides a blind hinge for furniture. The blind hinge comprises a connecting arm and a movable cup base which are connected through a swinging arm, wherein the hinge is internally provided with a torsion spring which is at least used for generating opening/closing acting force on the movable cup base. The blind hinge is characterized in that at least one supporting foot of the torsion spring is provided with a positioning block which is slidingly connected with the swinging arm; the positioning block is provided with a contact face and the contact face is slidingly connected with the swinging arm in an opening/closing process of the hinge; the positioning block is further provided with a limiting block; and a limiting part is fixedly arranged on one supporting foot and/or the swinging arm of the torsion spring in a limiting manner. According to the blind hinge disclosed by the invention, the positioning block is arranged on the supporting foot of the torsion spring so that the limiting block is fixedly arranged on one supporting foot and/or the swinging arm of the torsion spring in the limiting manner and is contacted with a hinge part; the mutual contact face of the positioning block and the hinge part is a curved surface, a plane or a combination of the curved surface and the plane so that the contact between the positioning block and the hinge part is in linear contact or face contact and the pressure of the contact part is greatly reduced; and the positioning block is a plastic anti-wearing plastic piece so that the rigid friction between the torsion spring and the hinge part is reduced, the abrasion is reduced, the service life of a product is prolonged and the aim of smoothly and reliably opening and closing the hinge is achieved.
