Disclosed is an easily foldable folding frame, comprising a first post (101), a second post (102), a third post (103), a fourth post (104), two or more layers of racks (201, 202, 203), a first connecting rod mechanism (301), a second connecting rod mechanism (302), a first support beam (401) and a second support beam (402). Each rack (201, 202, 203) is hinged between the four posts (101, 102, 103, 104) and is foldable upwards vertically, respectively; shaft pins (200, 300) of two hinges (2013, 2014) between two sub-racks (2011, 2012) on each rack (201, 202, 203) respectively pass through through-holes in rigid connecting portions (3013, 3023) on the two connecting rod mechanisms (301, 302), each shaft pin (200, 300) being rotatable in each of the through-holes, respectively. The two support beams (401, 402) are hinged between the four posts (101, 102, 103, 104) and are foldable inwards horizontally. When each of the racks (201, 202, 203) are unfolded to be horizontal, the back surface of the lowest rack (203) is in contact with the top portions of both the first support beam (401) and the second support beam (402). The folding frame has a more concise structure, is more stable, has good bearing capability, and is easy to fold.
