Hinge

Abstract

The invention discloses a hinge. The hinge comprises a hinge main body, a coupling component, a movable seat and an elastic component, wherein the coupling component is connected with a swinging block in a meshing manner, and forms a coupling relation with a buffering component of the hinge main body; the coupling component is also in pivot connection with the movable seat through a pivot connection part at one end; a rocker arm is arranged on the position, adjacent to the movable seat, of the coupling component in a pivot manner; one end of the rocker arm is arranged on a third shaft rod of the hinge main body in a pivot manner; a connecting hole of the elastic component is used for the passing of the third shaft rod of the hinge main body; two supporting ends are formed by equi-directionally extending from both sides of the connecting hole; the supporting ends are against the bottom wall surface of the hinge main body; an against end, which is located at the same side as the supporting ends, is convexly extended from the middle of the elastic component; and the against end is against the bottom surface of the coupling component. Through the structure, the hinge can generate free travel route and buffering travel route with proper angles, thus the effects of reducing the impact force and noise while opening and closing door plates are achieved.

Description

Technical field [0001] The invention relates to a hinge structure, in particular to a hinge which can generate a free stroke and a buffer stroke of an appropriate angle when the hinge main body and a movable seat are opened and closed, so as to reduce the impact force and noise of opening and closing door panels. Background technique [0002] In order to reduce the impact and noise of the furniture door on the main body of the furniture when the furniture door is closed, a damping device is usually installed between the furniture door and the main body of the furniture to slow down the closing speed of the furniture door and achieve the purpose of reducing the closing impact and noise of the door panel. Most of the existing hinges automatically switch to the pop-up state after the door is opened about 0°~60°. When the door is closed, the operator needs to apply a pressure greater than the self-elastic force of the hinge from the maximum opening angle of the door to close the door ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned existing hinges can realize silent closing, they do not consider that when the door panel is opened, the self-elastic force of the hinge will combine the weight of the door panel and the self-spring angle to generate a huge impact force, which will be transmitted to the joint between the hinge body and the furniture , which seriously affects the service life of the hinge and furniture; on the other hand, the existing hinge still has the problem of improper distribution of the spring return force, that is, the torsion angle in the closed state is the smallest, and the torsion angle in the opening process is the largest. It will make the spring very prone to elastic fatigue, causing the spring's restoring force to decrease rapidly, and even cause the spring body to break, so that the product has the defect of insufficient practicability
