Damping silent limit mechanism of furniture overturning device

Abstract

A damping, muting and limiting mechanism of a furniture turnover device comprises a movable element, a fixed element, a lever element, a damper and a connection arm assembly; the connection arm assembly at least comprises a first connection arm and a second connection arm; the movable element is hinged to the fixed element in a matched mode at least through the first connection arm and the second connection arm; the fixed element is provided with an elastic assembly; the movable element is arranged on the fixed element in an open and closed mode through elastic turning over of the elastic assembly; the lever element is rotationally arranged on the fixed element, one end of the lever element is interacted with the damper, and the other end of the lever element is provided with a damper closing area, a first damper opening area and a second damper opening area; and the first connection arm is provided with a service portion, the second connection arm is provided with a limiting portion, and a notch is formed between the service portion and the limiting portion. According to the damping, muting and limiting mechanism of the furniture turnover device, through structure improvement, no matter when a flap-up door of a piece of furniture is changed from an open state to a closed state, or from the closed state to the open state, the lever element can be forced to move on the fixed element according to the factory preset position, and the practicability is high.

Description

technical field [0001] The invention relates to a damping and silent limiting mechanism of a furniture overturning device. 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 mova...

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 achieves cushioning and damping through the elastic component, and the force during the closing or opening movement cannot achieve a uniform effect, and the elastic component has a large friction force and high noise when the upper flap is hinged to open and close, and it is not easy to use in the actual use process. Displacement is easy to appear in the center, resulting in the failure of the buffer damping. At the same time, the buffer damping force does not have the adjustment function, which cannot meet the needs of users.
