Referring to the drawings and initially to FIGS. 1-3, a modular frame with a U-shaped hook member in accordance with the present invention comprises multiple upright columns 10 each having a polygonal cross-section and multiple faces. At least two faces of each of the multiple upright columns 10 have multiple couples of first through hole 11 and second through hole 12 defined therein, wherein the coupled first through hole 11 and second through hole 12 horizontally correspond to each other and the multiple couples of first through hole 11 and second through hole 12 are longitudinally arranged in upright column 10. Multiple horizontal columns 20 are respectively connected to a corresponding one of the at least two faces of a corresponding one of the multiple upright columns 10. Each of the multiple horizontal columns 20 includes a tube 21 having a rectangular cross section. The tube 21 has two long sides and two short sides, wherein the two long sides of the tube 21 is parallel to an axis of the corresponding upright column 10. Two connecting blocks 30 respectively mounted into a corresponding one of two opposite ends of the tube 21. Two U-shaped hook members 40 are respectively mounted into a corresponding one of the two connecting blocks 30. Each U-shaped hook member 40 includes a first wing plate 41 and a second wing plate 42 connected to each other by a bridge 43 for forming a U-shaped structure. The first wing plate 41 has a first hook 411 extending therefrom and the second wing plate 42 has a second hook 421 extending therefrom. With reference to FIGS. 6, 7 and 7A, the first hook 411 and the second hook 421 respectively downward extend and engaged to a lower portion of a couple of first through hole 11 and second through hole 12. In the preferred embodiment of the present invention, the first through hole 11 and the second through hole 12 respectively have a narrowed lower portion for stably holding the first hook 411 and the second hook 421 in place.
A first protrusion 412 extends from a free end of the first hook 411 and hooks an upper edge of a corresponding one of the first through holes 11. A second protrusion 422 extends from a free end of the second hook 421 and hooks an upper edge of a corresponding one of the second through holes 12.
