Upturning structure used for automatic opening and closing of furniture

Abstract

An upturning structure used for automatic opening and closing of furniture comprises a connecting arm element, a support element, a middle element and an elastic assembly. A connecting arm groove is formed in the connecting arm element. An action portion is arranged on the support element. A moving shaft portion is arranged at one end of the middle support, the middle element is movably arranged on the connecting arm groove through the moving shaft portion, the other end of the middle element is rotationally arranged on the elastic assembly, and the connecting arm element is elastically hingedto the support element through the elastic assembly in an opening and closing manner. When the connecting arm element is hinged and closed to a certain position relative to the support element by opening the end position, the moving shaft portion and the action portion act on each other and slide along the track of the connecting arm groove and / or the action portion through action of the action portion, and the connecting arm element is suspended on the support element when the moving shaft portion slides. When the connecting arm element is hinged and opened to a certain position relative tothe support element by closing the end position, the moving shaft portion and the action portion are separated from each other and located to the connecting arm groove. Through the improvement of thestructure, practicality is high.

Description

technical field [0001] The invention relates to an upturning structure for automatic opening and closing of furniture. Background technique [0002] The Chinese patent document number is CN202039710U, which discloses a hinge on November 16, 2011. The curved end of the first rotating arm of this structure is rotatably connected to the base plate, and the curved end of the second rotating arm is rotatably connected to the base plate. The two ends of the above-mentioned connecting arms that can overlap with the respective straight ends of the first rotating arm and the second rotating arm at the same time are rotatably connected with the respective straight ends of the first rotating arm and the second rotating arm respectively, and the connecting arms are located at the first Between the rotating arm and the second rotating arm, the bent end of the first rotating arm is hinged with the free end of the movable rod of the gas rod, and the fixed rod of the gas rod can be movably ...

Problems solved by technology

It is said that this structure can reduce noise, and the closing or opening movement of the cabinet door is more flexible. During the movement of the cabinet door, the overall translational movement can avoid the situation that ordinary cabinet doors may hit the head; however, the upper The flap hinge only realizes cushioning and damping through the elastic device, which cannot achieve automatic opening and closing. At the same time, the force when opening and closing cannot achieve a uniform effect, and the elastic device has a large friction force and high noise when the hinge is opened and closed, which cannot meet the requirements.
