Damping force releasing and locking mechanism of furniture hinge

Abstract

A damping force releasing and locking mechanism of a furniture hinge. The damping force releasing and locking mechanism of the furniture hinge comprises a hinged cup base, a hinged arm, an elastic arm and a damper. One end of the elastic piece acts on the hinged cup base, and the other end of the elastic piece acts on the hinged arm. The damper is arranged on a concave portion of the hinged cup base, and the hinged arm is hinged to the hinged cup base and acts on the damper at least when the hinge is closed. A cushioning stroke of the damper is shortened, and cushioning force is generated. A cover plate is located on the concave portion. The damper is limited on the cover plate in a sliding mode and is provided with a locating portion. The cover plate is provided with a linear switch, and the linear switch is at least provided with an acting portion and a locking portion. The acting portion is acted through a tool or through manual work, the linear switch does linear movement on the cover plate and the locking portion of the linear switch is disengaged from and/or buckled with the locating portion of the damper, so the cushioning stroke of the damper can be released and/or locked. The damping force releasing and locking mechanism of the furniture hinge has the advantages of being simple and reasonable in structure, reliable in performance, easy to produce and implement, quick in adjustment, convenient to operate, wide in application range and the like, thereby being high in practicability.

Description

technical field [0001] The invention relates to a furniture hinge, in particular to a damping force release and locking mechanism for a furniture hinge. Background technique [0002] The Chinese patent literature number is CN201339380, which discloses a hinge on January 9, 2009, which includes a door box, a connecting rod, a hinge arm, a shift arm, a base, a buffer, a torsion spring, a link and a lever drive piece, and the link The device is a fan-shaped structure, which has a center hole and 3 peripheral holes, through which the center hole is movably connected to the hinge arm for positioning, and 1 peripheral hole is movably connected to the piston rod end of the buffer, and the remaining 2 peripheral holes are equipped with shafts. The lever driving piece is provided with an end hole and a middle hole, and the other end opposite to the end hole is provided with two fork mouths, and the lever driving piece is movably connected to the hinge arm through the middle hole, so ...

AI Technical Summary

Problems solved by technology

It is said that the structure is simple, the performance is reliable, and the use is flexible. However, due to the effect of the buffer, this structure requires a large force to open or close the door, which may easily cause damage to the handle on the door or the door cannot be closed properly. And the hinge of this structure is not convenient enough to use, and the buffer stroke of the buffer cannot be adjusted, which cannot meet the needs of users
