[0039] According to the sliding door mechanism of the refrigeration device according to the embodiment of the present invention, during the door opening process of the cabinet door, the door panel slides relative to the width direction of the cabinet door. Among them, during the sliding process of the door panel, through the swing of the first connecting rod 310, through the meshing drive of the first gear 311 and the second gear 321, and the setting of the connecting member 330, the corresponding second connecting rod 320 can follow and swing. The above structure improves the transmission stability and precise transmission, enables the door panel to slide to avoid interference with the side wall of the cabinet, and improves the user experience.

[0040] It can be understood that referring to Figure 1 and Figure 2, according to an embodiment of the present utility model, the first link 310 is provided with a first mounting portion for rotatably mounting the first gear 311, the second link 320 is provided with a second mounting portion for mounting the second gear 321, one end of the connecting member 330 is connected to the first mounting portion, and the other end of the connecting member 330 is connected to the second mounting portion. With the above structure, through the meshing transmission of the first gear 311 and the second gear 321, the swinging of the first link 310 can drive the corresponding swinging of the second link 320. The first gear 311 is mounted on the first link 310 through the first mounting portion, the second gear 321 is mounted on the second link 320 through the second mounting portion, and both ends of the connecting member 330 are connected to the first mounting portion and the second mounting portion. The mounting manner of the connecting member 330 is beneficial to ensuring that the first link 310 and the second link 320 always maintain a transmission relationship, and ensuring their stable installation, preventing loosening or falling off during operation, simplifying the overall structure, and reducing the connection points between components.
