[0020] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, but the embodiment should not be understood as the limitation of the utility model.
[0021] The utility model discloses as shown in Figures 1 to 6 :
[0022] A kind of commercial vehicle bunk drawer box hopper's reversible support mechanism, including drawer body 1, drawer body front end is equipped with drawer panel 2, the width of both sides of drawer panel is greater than drawer body, the bottom of the front end of drawer body is rotatably connected with support rod 4 by hinge 3 on both sides, one end of support rod passes through hinge, end is equipped with limit cap 5, spring 6 is sleeved on support rod between limit cap and adjacent hinge,
[0023] Supporting block 7 is symmetrically fixed on both sides of support rod between two hinges, and a movable gap is reserved between supporting block and hinge, the other end of support rod extends outward through hinge, and L-shaped handle 8 is connected to the end, the other end of L-shaped handle extends to the cavity position between the side of drawer body and the side of drawer panel, to avoid interference.
[0024] The side of drawer body 1 is provided with a limiting component for limiting the forward and backward angles of the support rod, one of which is used to limit the rotation of the supporting block to the vertical support state, and the other is used to limit the upward rotation of the supporting block to the horizontal state.
