Abstract
The utility model provides a furniture hinge, comprising a fixed arm and a movable cup base which are connected through a swing arm component, wherein the hinge is provided with a spring which at least closes the movable cup base. The furniture hinge is characterized in that the spring is at least composed of a main spring and an auxiliary spring. More than two springs are mounted in the hinge so that the hinge is totally opened or closed by the force of the spring when the hinge is opened or closed to a certain degree. During the process, the force of the hinge is born by the spring, which greatly improves the service life of the spring; the advantage of the service life of the hinge with over two springs is embodied in testing the working service life of the hinge (the service life of the opening and closing operation is over 50,000 times); meanwhile, the diameter of the spring is adequately reduced.
