Side-by-side combination refrigerator and vertical beam guiding device thereof

The invention discloses a side-by-side combination refrigerator and a vertical beam guiding device thereof. The side-by-side combination refrigerator comprises a refrigerator body, a first door, a second door and a vertical beam in rotating connection with the second door. The vertical beam guiding device comprises a linking piece, a guiding piece and a driving component, wherein the linking piece can move forward when the first door is opened; the guiding piece comprises a guiding structure; the guiding structure is matched with a guided structure on the vertical beam so as to guide the vertical beam to rotate; the driving component comprises a body, a first driving mechanism and a second driving mechanism; the first driving mechanism comprises a first guiding slot and a first convex column moveably accommodated in the first guiding slot; the first guiding slot and the first convex column are respectively arranged on the body and the linking piece; the second driving mechanism comprises a second guiding slot and a second convex column moveably accommodated in the second guiding slot; the second guiding slot and the second convex column are respectively arranged on the body and the guiding piece; when the linking piece moves forward, the guiding piece is driven by the driving component to move backward and the guiding structure is matched with the guided structure so as to rotate the vertical beam.
