    • BACKGROUND
  • At present, conventional refrigerated compartments in the market are generally configured in refrigerators equipped with side-by-side doors, such as French refrigerators, multi-door refrigerators and the like. Typically a turnover beam capable of turning over at 90 degrees is designed on a refrigerator door on one side of the refrigerator. It is generally required that when the door is closed, the turnover beam is parallel to the door, and when the door is opened, the turnover beam is perpendicular to the door. It is a common practice that a torsion spring is used to ensure that the turnover beam is only maintained stable at either of the two positions, that is, a door open position or a door close position.
  • In the above design, the torsion spring is typically provided outside the turnover beam, thereby affecting appearance of the refrigerator. In addition, service life of the torsion spring is limited, and opening and closing during long-term use of the refrigerator may cause damages to the torsion spring, which resulting in failure of the turnover beam. During shift of the torsion spring between the two states, the torsion spring is definitely subjected to a dead center. In this case, if the design is not proper, the turnover beam may remain at the dead center, affecting normal use of the refrigerator.

    DETAILED DESCRIPTION
  • The present invention is further described with reference to a specific embodiment.
  • As illustrated in FIG. 1, FIG. 2, and FIG. 3, the present invention provides a turnover beam, comprising: a front cover plate 1, a rear cover plate 2, a mount 3, and an elastic structure 4. The front cover plate 1 and the rear cover plate 2 mate with each other to form a cavity, wherein the mount 3 and the elastic structure 4 are positioned in the cavity. The mount 3 comprises a fixing position 32 coupled to a refrigerator door and a rotating shaft 31 hinged to a hole 11 provided on the front cover plate 1, wherein the rotating shaft 31 is provided with a limiting stopper 33. One end of the elastic structure 4 is fixed into the cavity, and the other end of the elastic structure 4 is a free end which elastically mates with the limiting stopper 33, wherein when the refrigerator door is at either of two limiting positions, the free end of the elastic structure 4 is positioned on two sides of the limiting stopper 33, and when the refrigerator door is between the two limiting positions, the free end of the elastic structure 4 is in elastic extrusion mating with the limiting stopper 33.
  • According to the present invention, the front cover plate 1 is fixed to the rear cover plate 2 via snap-fitting. In addition to some parts in the present invention, a foam, a heating wire and the like are also defined in the above cavity. The mount 3 is fixed onto a container rib on a lateral side of the door.
  • Specifically, the elastic structure 4 is an elastic piece, the limiting stopper 33 of the mount 3 is of an arch structure, one end of the elastic structure 4 is fixed onto the front cover plate 1, and the two limiting positions are a door close position and a door open position.
