According to a preferred embodiment, the wall of the box 10 is provided with a first groove 102, and the first groove 102 is recessed to a depth no less than the thickness of the table top, and the table top is accommodated in the first groove 102 when the table top is folded, as shown in fig. 1 or fig. 2. The first recess 102 may be used to receive the first table top 201 and/or the second table top 301. Preferably, the first recess 102 is adapted to receive the second table top 301, as shown in figures 1 or 2. According to the preferred technical scheme of the embodiment, the first groove 102 is formed in the wall surface of the box body 10, the concave depth of the first groove 102 is not smaller than the thickness of the table top, when the table top is in a folded state, the table top can be accommodated through the first groove 102, and a gap between the table top in the folded state and the wall surface of the box body 10 is avoided.

According to a preferred embodiment, the table tops comprise a first table top 201 and a second table top 301, wherein the first table top 201 and the second table top 301 are rotatably connected to the wall surface of the housing 10 at different heights, and the first table top 201 and the second table top 301 are spaced apart from each other in the unfolded state, and the first table top 201 and the second table top 301 are overlapped with each other in the folded state, as shown in fig. 1 or fig. 2. Specifically, the first tabletop 201 is rotatably connected with a higher wall surface of the box body 10, the first tabletop 201 is in an unfolded state by rotating upwards, and is in a folded state by rotating downwards; the second table top 301 is rotatably connected to a lower wall of the box 10, the second table top 301 is unfolded by rotating downward and folded by rotating upward, and the first table top 201 and the second table top 301 are folded to form a double-layered table top at intervals after being unfolded, as shown in fig. 1 or fig. 2. The first desktop 201 and the second desktop 301 may be unfolded for use at the same time, or the first desktop 201 or the second desktop 301 may be unfolded separately. The folding table mechanism of the preferred technical scheme of this embodiment has double-deck interval and sets up folding desktop, can satisfy the multiple user demand of little living environment, has avoided the refrigerator that has folding table among the prior art to cause usable desktop area limited problem for the individual layer desktop. Without being limited thereto, the folding table mechanism in the preferred embodiment may also include a third table top, and even a fourth table top.

According to a preferred embodiment, the first desktop 201 is unfolded and folded as follows: when the first desktop 201 needs to be used, the handle part 2011 is held by hands to rotate the first desktop 201 to the horizontal position and fix the first desktop 201, so that the first desktop 201 is unfolded; when the first table top 201 is not needed to be used, the handle portions 2011 are lifted to rotate the first table top 201 to the vertical position, so that the first table top 201 is folded.

According to a preferred embodiment, the second table top 301 may be unfolded and folded as follows: when the second desktop 301 needs to be used, the fixing of the second desktop 301 is released by slightly pressing the lock catch 303, and the second desktop 301 is rotated downwards to the horizontal position and fixed by using the gravity of the second desktop 301, so that the second desktop 301 is unfolded; when the second table top 301 is not needed to be used, the second table top 301 is rotated upwards to the vertical position, and the second table top 301 is fixed by the locking hook 302 and the locking body 304, so that the second table top 301 is folded.
