The embodiment of the invention provides a side-by-side combination refrigerator with an overturning beam, and relates to the technical field of refrigeration equipment. The side-by-side combination refrigerator is invented for solving the problem that the locking reliability of an overturning beam and a door body in the side-by-side combination refrigerator with the overturning beam in the prior art is low. The side-by-side combination refrigerator with the overturning beam comprises a box, two door bodies are arranged on the box in parallel, the overturning beam is hinged to one door body, a self-locking mechanism is arranged between the overturning beam and the door body and comprises a trigger rod, a locking ring and a locking shaft, the trigger rod is connected to the overturning beam in a sliding manner in the vertical direction, a first stopping part is arranged on the inner wall of the locking ring, a second stopping part is arranged on the locking shaft, the first stopping part can be matched with or can break away from the second stopping part in the process that the door body is opened or closed, and therefore locking or unlocking of the overturning beam relative to the door body is achieved. The side-by-side combination refrigerator with the overturning beam in the embodiment is used for storing objects at a low temperature.
