In this embodiment, the first connecting device 530 includes a first transmission rod 710, a first pulley 720, a first synchronous belt 730 and a first connecting member 740, as shown in fig. 5 and 6.

It can be understood that two first pulleys 720 are provided, the first synchronous belt 730 is wound around the two first pulleys 720, and since the two first connecting devices 530 are in transmission connection with the same retraction driving source 520, the first transmission rod 710 extends along the left-right direction, two ends of the first transmission rod 710 are respectively in transmission connection with the output end of the retraction driving source 520 and one of the first pulleys 720, and the first synchronous belt 730 is connected with the retraction placement structure 510 through the first connecting member 740.

Specifically, the first pulleys 720 are provided with two first pulleys 720 and are symmetrically arranged in front and back directions, the first synchronous belts 730 are in transmission engagement with the outer cambered surfaces of the two first pulleys 720, the movable ends of the first connecting devices 530 are first connecting members 740, and the first connecting members 740 can connect the first synchronous belts 730 with the first inward-retreating placement structures 510 so as to drive the inward-retreating placement structures 510 to move back and forth.

It can be understood that the two first pulleys 720 are fixed on the left and right inner side walls of the cabinet 200 through the mounting seats with shafts, and the first pulleys 720 are rotatably connected with the mounting seats; the axes of the two first pulleys 720 extend along the left-right direction, and because the two first pulleys 720 are symmetrical in front-back direction, the upper and lower sections of the first synchronous belt 730 extend along the front-back direction, the first synchronous belt 730 is fixedly connected with the first connecting piece 740 through a connection mode such as a screw, the first connecting piece 740 is fixed with the retraction placing structure 510 through the screw, when the retraction driving source 520 is started, the first synchronous belt 730 drives the first connecting piece 740 to move back and forth, so that the retraction placing structure 510 moves back and forth relative to the storage cavity 210, and further the retraction door 410 is driven to move back into the storage cavity 210 or move forward to the front of the storage cavity 210.

It is understood that the retraction mechanism 500 is only used to drive the retraction door 410 to move back and forth into the storage cavity 210, so that the distance of the movement of the retraction mechanism 500 is small, and the first connecting member 740 fixed to the first timing belt 730 does not contact the two first pulleys 720.

Therefore, when the two inner doors 410 move backward into the storage cavity 210 through the inner mechanism 500, the sliding driving source 610 is started, and the second connecting device 620 can drive the two sliding door assemblies 420 to move up and down, so that the storage cavity 210 located in the middle is exposed or blocked.

It is understood that, in order to further stabilize the movement of the sliding door assembly 420, the sliding direction of the sliding door assembly 420 is prevented from being deviated from a straight line extending up and down, and therefore, each sliding door mechanism 600 includes two second connecting devices 620, the two second connecting devices 620 are laterally symmetrical with respect to the sliding door assembly 420 and are respectively connected to the left and right sides of the sliding door assembly 420, the two second connecting devices 620 are connected to the same sliding driving source 610, so that the sliding driving source 610 is simultaneously transmitted to the two second connecting devices 620, and both the left and right ends of the sliding door assembly 420 are synchronously moved, thereby preventing the sliding door assembly 420 from being deviated, and saving the setting cost of the sliding driving source 610.

In the present embodiment, the slide driving source 610 is a stepping motor, a servo motor, or the like, which can be rotated in the forward and reverse directions. The sliding driving source 610 is located in the storage cavity 210, and may be fixed to the cabinet 200 by a connection method such as a screw, a welding, etc.
