Blind hinge used for furniture

摘要

A blind hinge used for furniture, comprising a movable cup holder provided on the furniture door body, an adjusting base provided on the furniture body, a rotary arm connected between the movable cup holder and the adjusting base as well as an elastic element designed to generate opening/closing acting force on the movable cup holder. The adjusting base is designed as L-shape or bent shape to realize three-dimensional or two-dimensional adjustment to the hinge; a convex step used to support the elastic member is formed on the bottom base of the movable cup holder; the elastic member is a torsion spring, with its section on at least one of its end parts being square or circular; the connecting piece is provided with a boss and a convex part.

1. A blind hinge used for furniture, comprising a movable cup holder provided on a furniture door body, an adjusting base provided on a furniture body, a rotary arm connected between the movable cup holder and the adjusting base as well as an elastic element designed to generate opening/closing acting force on the movable cup holder; wherein the adjusting base is designed as one of an L-shape or bent shape and to realize three-dimensional or two-dimensional adjustment to the hinge; a convex step used to support the elastic element is integrally formed on a bottom base of the movable cup holder; the elastic element is a torsion spring, with a section on at least one of the torsion spring end parts being square or circular; the adjusting base comprises a movable plate, a base plate and a connecting piece and the connecting piece is provided with a boss and a convex part; the rotary arm is movably assembled on a bent plane on one side of the connecting piece, and the adjustment to the relative positions of the rotary arm and connecting piece is completed through a first eccentric adjustment rivet; wherein the movable plate and the base plate are in turn assembled in the bent plane on the opposite side of the connecting piece, the adjustment to the relative positions of the movable plate and the connecting piece is completed through a second eccentric adjustment rivet, and the adjustment to the relative positions of the base plate and the connecting piece is completed through a third eccentric adjustment rivet, so that the three-dimensional adjustment to the hinge is realized; wherein the first eccentric adjustment rivet, the second eccentric adjustment rivet and the third eccentric adjustment rivet are arranged in triangle form; wherein the first eccentric adjustment rivet passes through a first adjusting hole on the rotary arm and is assembled on the connecting piece; wherein the second eccentric adjustment rivet passes through a second adjusting hole on the connecting piece and is assembled on the movable plate; wherein the third eccentric adjustment rivet passes through a third adjusting hole on the movable plate and is assembled on the base plate; and wherein a fixed plate is provided at the bottom of the movable plate and is positioned in coordination with the second eccentric adjustment rivet and/or the third eccentric adjustment rivet.
