Control device of furniture hinge damping force

Abstract

A control device of furniture hinge damping force comprises an outer rocker, an inner rocker, a connecting arm, and a moving cup base, wherein the connecting are is connected with the moving cup base through the outer rocker and the inner rocker. A damper is disposed in the connecting arm. An elastic part at least generating opening-closing force upon the moving cup base is disposed in a hinge. The damper is a linear damper, one end of the linear damper is disposed on the connecting arm, and the other end of the linear damper is connected with a swing block at during closing of the hinge. The connecting arm is provided with a release mechanism. The path of the swing block from an initial position to a limited position is regulated by the release mechanism so as to achieve release and recovery of hinge damping force. The inner rocker generates acting force upon the swing block at least when the release mechanism is not regulated. The damper is further provided with a return mechanism corresponding to the swing block. Through modification on the structure, the lifetime of the damper is prolonged effectively, the damping force of the hinge can be regulated according to users' needs so as to achieve controlling closing speed and force of the hinge and reduce collision of furniture, and the control device is low in noise and highly practical.

Description

technical field [0001] The invention relates to a furniture hinge, in particular to a control device for the damping force of the 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 that t...

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 body, which may easily cause damage to the handle on the door body or the door body cannot be closed properly. And the hinge of this structure is not convenient enough to use, and the buffering time of the buffer cannot be adjusted, which cannot meet the needs of users
