Abstract

The invention relates to an all-purpose turning joint which is a furniture member and comprises a right connecting plate and a left connecting plate, each of the two connecting plates is provided with a matching bearing surface and a gear surface at one end, the two connecting plates can enlarge the rotation angle through a plurality of steps of connecting device, each step of connecting device comprises an upper gear form plate and a lower gear form plate, the two ends of the upper gear form plate and the lower gear form plate are all provided with a bearing surface and a gear surface, the corresponding upper gear form plate and the lower gear form plate are movably connected through a rotation shaft; when the two connecting plates are stressed by the rotating force from the respective gear faces, the rotating force is stably transferred through the engaged gear surface and the limiting effect between the neighboring rotation shafts, and thus, the rotation angle between the two connecting plates is adjustable within the range of the gear face. Each rotation connecting point is all designed to the connection with the connecting plate, the connecting device, a liner bushing, an elastic gasket through the rotation shaft, and thus, the rotation position of a hinge can stop at any angle. Compared with the existing art, the invention has the advantages that the range of the rotation angle is large, the rotation position can stop at any angle, the rotation is stable, noise-free and the bearing strength is large, etc.

Description

Technical field: [0001] The invention relates to a furniture component, in particular to a universal rotating hinge for an adjustable backrest, armrest or headrest of sitting or lying furniture. Background technique: [0002] The hinges currently used on furniture are usually installed between a support cam and a pressing boss by means of external gears, so that the entire effective range that works with the locking pawl is limited by the support cam on one side and the other side by the support cam. Restricted by the hold-down boss. Therefore, the entire rotation angle of the hinge is limited to a certain extent, and certain noises will be generated during the mating process of the locking pawl and the gear. Invention content: [0003] The technical problem to be solved by the present invention is to provide a universal rotary hinge with arbitrarily adjustable rotation angle, stable rotation, no noise and certain supporting force. [0004] The technical solution adopted...
