Abstract:
A foldable hand truck, comprising a frame, a hand-pulling rod (5) provided at the front of the frame, and quick-remove wheels (6) provided at the bottom of the frame. The frame comprises a bottom frame (1), a front frame (2), a rear frame (3), and side frames (4) that are foldable. A compartment (7) is detachably provided in the frame. The front frame (2) and the rear frame (3) are symmetrically provided on front and rear sides of the bottom frame (1). The side frames (4) are symmetrically provided on left and right sides of the bottom frame (1). The front frame (2) and the rear frame (3) each comprise vertical left and right supporting rods (20). The quick-remove wheels (6) are mounted at lower ends of the supporting rods (20). Two hinged connecting rods (21) crossing in an X shape are connected between the supporting rods (20). The side frames (4) are in the shape of bridges. Each side frame (4) comprises an I-shaped bracket (41) located in a middle portion. A pair of first inclined rods (42) and a pair of second inclined rods (43) are respectively hinged to upper and lower ends of the I-shaped bracket (41). The hand-pulling rod (5) is formed by assembling a handle (51), a pulling rod (52), an omnidirectional frame (53), and a supporting seat (54). Such a structure is reasonably designed; the frame is easy to fold; steering of the hand-pulling rod is flexible; the quick-remove wheels and the compartment are quick to remove; and the hand truck has a large bearing capacity and a firm and stable structure.
