Problems solved by technology

Due to the small diameter of the torsion spring steel wire, the contact between the connecting foot and the parts is very small, almost a point contact, so the pressure at the contact is strong, resulting in serious wear between the parts, affecting the life of the torsion spring and even the entire hinge

Abstract

The invention relates to a hinge which comprises more than one torsional spring, wherein the torsional spring comprises a first connecting foot and a second connecting foot, and the first and the second connecting feet are respectively connected with two parts of the hinge, which move relatively during the opening and closing process; a connecting block is fixedly arranged on at least one connecting foot of the torsional spring; and the connecting block is provided with a contact surface and connected with one part of the hinge through the contact surface. The connecting block is arranged on the connecting leg of the torsional spring provided by the invention, and the connecting block is used for being in contact with the parts in the hinge; furthermore, as the surface of the connecting block, which is in contact with the part of the hinge is large in width and the contact surface can be designed into a plane, a curved surface or the combination of the plane and the curved surface according to the motion needs of the hinge, the contact between the connecting block and the part of the hinge becomes line contact or surface contact, the pressure at the contact part is greatly reduced, the abrasion between the torsional spring and the part of the hinge is further reduced, the service life is prolonged and the purpose of smoothly and reliably opening and closing the hinge is also achieved.

Description

technical field [0001] The invention relates to a hinge, in particular to a furniture hinge. Background technique [0002] The connection of the torsion spring in the current furniture hinge can be found in Figure 21 and Figure 22 , the two connecting feet 17.1 of the torsion spring 17 are respectively directly connected with the two parts that move relative to each other during the opening and closing of the hinge. Because the diameter of the torsion spring steel wire is very small, the contact position between the connecting pin and the parts is very small, almost a point contact, so the pressure at the contact point is strong, resulting in serious wear between the parts, affecting the life of the torsion spring and even the entire hinge. Contents of the invention [0003] The purpose of the present invention is to provide a hinge with simple and reasonable structure, less wear between the torsion spring and the hinge parts, long service life, smooth and reliable oper...
