A foldable cabinet, comprising:

• a framework provided with two side frames which are oppositely disposed and vertically arranged;
• panel assemblies provided into two sets, corresponding to the two side frames, respectively;
• wherein each set of panel assembly comprises a side board and a back board, each side board is provided with a side board body, and first connecting portions and a first turning portion which are disposed on two lateral sides thereof, each back board is provided with a back board body, and a second turning portion and a fourth connecting portion which are disposed on two lateral sides thereof, the first connecting portions are hingedly connected with the side frames through first shafts which are vertically arranged, the first turning portion is hingedly connected with the second turning portion through a vertically arranged second shaft, and the fourth connecting portions of the two back boards are detachably connected;
• wherein each first connecting portion extends from a portion of the edge of respective side board body and bends to define a first groove, the first turning portion is provided with a second connecting portion bending to define a third groove, the second turning portion is provided with a third connecting portion bending to define a fourth groove, each side frame is provided with a fifth connecting portion bending to define a second groove, each first shaft is disposed to extend through the first groove of the first connecting portion and the second groove of corresponding fifth connecting portion, each second shaft is disposed to extend through the third groove of the second connecting portion and the fourth groove of corresponding third connecting portion;
• when the foldable cabinet is in a folded state, the side boards, the back boards, and the framework are superposed, with the back boards being located between the side boards and the framework;
• when the foldable cabinet is in an unfolded state, the side boards are located between the framework and the back boards in such a manner that the side boards are perpendicular to the framework, and the sideboards are perpendicular to the back boards;
• and
• throughout the folded state and the unfolded state of the foldable cabinet and a transition state therebetween, an opening of the first groove of each first connecting portion and an opening of the second groove of corresponding fifth connecting portion always face different directions, and an opening of the third groove of each second connecting portion and an opening of the fourth groove of corresponding third connecting portion always face different directions;
• wherein each first connecting portion is provided on a portion of an edge of the side board;
• the side frame is further provided with a side frame body and a first limiting portion, and the first limiting portion and the fifth connecting portion are located behind the side frame body, a portion of the edge of the first limiting portion extends and bends to define the fifth connecting portion;
• the first turning portion is further provided with a second limiting portion, the second connecting portion is connected with the side board body through the second limiting portion, and a portion of an edge of the second limiting portion extends and bends to define the second connecting portion;
• the second turning portion is further provided with a third limiting portion, the third connecting portion is connected with the back board body through the third limiting portion, and a portion of an edge of the third limiting portion extends and bends to define the third connecting portion;
• and
• when the foldable cabinet is in the unfolded state, a portion of an edge of the side board body abuts against the fifth connecting portion, a portion of an edge of the first limiting portion abuts against the first connecting portion, a portion of an edge of the second limiting portion abuts against the third connecting portion, and a portion of an edge of the third limiting portion abuts against the second connecting portion.
