Blind hinge structure used for furniture

摘要

A blind hinge structure 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; wherein the adjusting base is designed to realize three-dimensional or two-dimensional adjustment to the hinge; a convex step used to support the elastic member is integrally formed on the bottom wall 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 present utility model enables the structure among the rotary arm, the adjusting base and the adjusting components to have higher firmness and even compact assembly, improves strength and extends the service life.

1. A blind hinge structure used for furniture, comprising:
a movable cup holder provided on the furniture door body, an adjusting base provided on the furniture body, the adjusting base comprising a rotary arm rotatably connected to the movable cup holder, at least one elastic element that generates opening/closing acting force on the movable cup holder by engaging the movable cup holder with a bent end of the elastic element and engaging the rotary arm with a straight end of the at least one elastic element; wherein the adjusting base further comprises a movable plate and a base plate, the movable plate is movably provided between the rotary arm and the base plate, the rotary arm is connected with the movable plate through an adjusting screw and a first eccentric adjustment rivet, and the movable plate is connected with the base plate through a second eccentric adjustment rivet, so that two or three-dimensional adjustment relative to the furniture door body is realized; wherein at least one convex step used to support the bent end of one of the at least one elastic members is integrally formed on the bottom walls on one or both sides of the movable cup holder; the at least one elastic member is a torsion spring, with its section on at least one of its end parts being square or circular; wherein the adjusting screw, the first eccentric adjustment rivet and the second eccentric adjustment rivet are arranged in triangle form on the whole; the adjusting screw passes through a first adjusting hole on the rotary arm and is buckled in an open slot on the movable plate; the first eccentric adjustment rivet passes through a second adjusting hole on the rotary arm and is assembled in an assembly hole on the movable plate; the second eccentric adjustment rivet passes through a third adjusting hole on the movable plate and is assembled on a mating hole on the base plate; a fixed plate is provided at the bottom of the base plate and is configured to engage with at least one of the first eccentric adjustment rivet and the second eccentric adjustment rivet.
