Damping and hovering structure of furniture tilt-up door

Abstract

A damping and hovering structure of a furniture tilt-up door comprises a fixing seat, a spring, a connecting arm component and a retaining element. The connecting arm component 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 is hinged to the fixing seat, the middle arm is hinged to the fixing seat and / or the retaining element, and the retaining element is opened and closed on the fixing seat in a turnover manner under the action of the spring; a damping and hovering unit is arranged on the retaining element and comprises a hovering damper and a pushing element; when the retaining element is opened and closed within a certain acute angle range, the hovering damper is at the initial position and basically does not generate damping force; when the retaining element is opened and closed beyond the certain acute angle range, the middle arm acts on the hovering damper through elasticity of the spring and / or loading capacity of the retaining element, the hovering damper generates damping force, and elasticity of the spring and / or loading capacity of the retaining element is offset through the damping force, so that the retaining element can hover anytime when being opened and closed beyond the certain acute-angle range.

Description

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

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 hinge of the flap door only realizes buffering and damping through the elastic device, and the force during the closing movement or opening movement cannot achieve a uniform effect, and the elastic device has a large friction force and high noise when the upper flap door is hinged to open and close, and the upper flap door opens at a certain angle Then it will automatically close due to its own weight, which cannot meet the needs of users
