Folding door capable of resetting automatically
The invention discloses a folding door capable of resetting automatically. The folding door capable of resetting automatically comprises first connecting shafts, second connecting shafts, at least two door hinges and a sliding track, wherein the door hinges are rotatably hinged to the first connecting shafts so as to fold or unfold around the first connecting shafts; the sliding track is arranged at the upper end or the lower end of the first connecting shafts so that the door hinges slide along the sliding track and fold or unfold; each door hinge comprises at least four arc hinges; the arc hinges are pairwise and rotatably hinged to the second connecting shafts, and fold or unfold around the second connecting shafts to form geometrical barrels; a cavity is formed in each geometrical barrel; and an elastic air bag is arranged in each cavity so that the door hinges can reset automatically after folding or unfolding. The arc hinges are rotatably hinged to the connecting shafts to form the door hinges with the cavities in the middles, and sound-insulation and thermal-insulation functions of the door hinges are fulfilled. Sound is reflected by uniform concave and convex structures on the outer surfaces of the door hinges, and the sound shielding effect of the door hinges is improved.
