  • the hinge mechanism 1b is formed by integrating the lower hinge mechanism 1 and 1a of the upper door with the upper hinge mechanism 1 and 1a of the lower door, which can reduce the space for setting the hinge mechanism 1b on the middle beam 101, reduce the thickness of the middle beam 101, enhance the overall aesthetics of the refrigeration device 10, increase the storage volume inside the refrigeration device 10, and reduce the cost.
  • the fixing seat 11b includes a fixing plate 113 for fixing on the box body 2 and a horizontal plate 114 fixed on the fixing plate 113.
  • the hinge mechanism 1b includes two groups of connecting rod assemblies 12 and 12a respectively arranged on the upper and lower sides of the horizontal plate 114, and the door body fixing rods 131 and 131a in the two groups of connecting rod assemblies 12 and 12a are respectively connected to the two door bodies 3 arranged on the upper and lower sides, thereby reducing the space for setting the hinge mechanism 1b on the middle beam 101, reducing the thickness of the middle beam 101, enhancing the overall aesthetics of the refrigeration device 10, increasing the storage volume inside the refrigeration device 10, and reducing the cost.
  • the structures of the two groups of connecting rod assemblies 12 and 12 a can follow the structures of the connecting rod assemblies 12 and 12 a described above, and will not be described in detail herein.
  • the hinge mechanism 1 in the present invention by setting a connecting rod assembly 12 between the door body 3 and the box body 2, and the connecting rod assembly 12 includes at least one group of four-bar groups.
  • the connecting rod assembly 12 can drive the door body 3 to translate along a preset trajectory while rotating and opening. It has a simple structure and a small size. At the same time, it can increase the opening angle of the door body 3.
