Adjustable damping hovering structure of flap-up door of furniture

Abstract

The invention discloses an adjustable damping hovering structure of a flap-up door of furniture. The adjustable damping hovering structure comprises a fixing seat, a spring, a connecting arm assembly and a stopping and butting element. The connecting arm assembly at least comprises a first connecting arm, a second connecting arm and a middle arm; the first connecting arm and / or the second connecting arm are hinged to the fixing seat, the middle arm is hinged to the fixing seat and / or the stopping and butting element, the stopping and butting element can be opened or closed on the fixing seat under the effect of the spring, a damping hovering device is arranged on the stopping and butting element, the stopping and butting element can be hovered at any time when the damping hovering device carries out opening and closing activities outside a certain acute angle range, an adjusting assembly is arranged on a displacement element, and the displacement element can be repositioned relative to the stopping and butting element by the aid of the adjusting assembly, so that damping force of a hovering damper can be ultimately adjusted. The adjustable damping hovering structure has the advantages that the improved adjustable damping hovering structure is simple, reasonable, safe and reliable, is easy to manufacture and implement, convenient to operate, wide in service range, low in noise and high in practicality, can be quickly adjusted, can be opened and closed smoothly and is low in collision when opened and closed, and the like.

Description

technical field [0001] The invention relates to a damping and hovering structure of an upward flap of furniture, in particular to an adjustable damping and hovering structure of an upward flap 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...

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, and the force during the closing or opening movement cannot achieve a uniform effect, and the elastic device has a large friction force and high noise when the upper flap is hinged to open and close, and the damping cannot be adjusted at any time The size of the force, the upper flap door will automatically close due to its own weight after opening a certain angle, which cannot meet the needs of users
