Rotatable positioning hinge structure for furniture
A rotatable positioning hinge structure for furniture comprises a hinge device. The hinge device comprises a positioning element and a fixed element which are mutually and rotationally connected through an adapter unit. The fixed element is provided with an elastic assembly acting on the positioning element elastically. The positioning element is formed by stamping metal materials integrally, and an arc sliding part is arranged in the middle of the positioning element. The arc sliding part is provided with at least three grooves in a spaced manner. The elastic assembly is arranged on the fixed element, and comprises springs and an elastic acting piece. When the positioning element rotates relative to the fixed element, the elastic acting piece acts on the arc sliding part of the positioning element and the grooves due to elasticity of the springs, so that when the positioning element rotates relative to the fixed element, the stepless elastic hovering at any time and suspension limiting at least three positions of the positioning element relative to the fixed element are achieved. The rotatable positioning hinge structure for the furniture has the beneficial effects of being simple and reasonable in structure, excellent in performance, rapid in assembly, convenient to operate, low in manufacturing cost, easy to produce and implement, safe, reliable, high in practicability, and the like.
