Connecting device

A connecting device for interconnecting a vertical tube and a plurality of display cabinets for carrying display modules, the vertical tube including a plurality of vertical outer surface portions, said connecting device comprising:

• a first connecting frame adapted for mounting the display cabinets thereon, adapted to be disposed in front of the vertical tube, and adapted to abut against a front one of the outer surface portions of the vertical tube that faces the display cabinets;
• a second connecting frame spaced apart from said first connecting frame along a front-rear direction, adapted to be disposed behind the vertical tube, and adapted to abut against a rear one of the outer surface portions of the vertical tube that faces away from said first connecting frame;
• and
• a fastening unit including two first fastening sets and a plurality of second fastening sets, said first fastening sets being spaced apart from each other along a left-right direction transverse to the front-rear direction and fastening said first connecting frame securely to said second connecting frame so as to clamp the vertical tube between said first connecting frame and said second connecting frame, said second fastening sets being adapted to fasten the display cabinets securely to said first connecting frame;
• wherein said first connecting frame includes a vertical supporting plate, two vertical bent plates, and two first vertical connecting plates, said vertical supporting plate having a vertical mounting surface adapted for mounting the display cabinets thereon and a back surface opposite to said mounting surface along the front-rear direction, said second fastening sets being adapted for fastening the display cabinets securely to said vertical supporting plate, said bent plates extending rearwardly from said back surface of said vertical supporting plate and being spaced apart from each other along the left-right direction, each of said first connecting plates being spaced apart from said vertical supporting plate, said second connecting frame including two vertical second connecting plates corresponding respectively in position to said first connecting plates along the front-rear direction, each of said first connecting plates being spaced apart from the respective one of said second connecting plates by a gap, each of said first fastening sets fastening a respective one of said first connecting plates to a corresponding one of said second connecting plates;
• and
• wherein said mounting surface includes two vertical mounting surface portions that are connected perpendicularly to each other at rear ends thereof to define a first included angle of 90 degrees therebetween, and that are adapted for mounting the display cabinets thereon,
• said first connecting frame further including two vertical first abutment plates connected perpendicularly to each other, and two vertical side walls extending respectively and perpendicularly from outer ends of said first abutment plates so as to cooperate with the first abutment plates to form a W-shape, each of said first abutment plates having a vertical first abutment surface adapted to abut against the front one of the outer surface portions of the vertical tube, said first abutment surfaces of said first abutment plates defining a second included angle equal to the first included angle.
