Damping and hovering structure of furniture tilt-up door
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.
