[0034] See also Figure 2-3In order to prevent the goods from tipping over, the adjustment mechanism 2 in this embodiment includes a driving assembly and a lifting assembly. The driving assembly includes a box body 201, a movable rod 202, two first gears 203, four second gears 204, four screw rods 205, four movable sleeves 206, four hinged rods 207 and two U-shaped seats 212. The box body 201 is fixed to the lower surface of the bottom plate 1. The movable rod 202 is rotatably connected between the front and rear side walls of the inner cavity of the box body 201 through a bearing. The two first gears 203 are fixed to the outside of the movable rod 202. The four second gears 204 are divided into two groups. The two groups of second gears 204 are respectively meshed with the outsides of the two first gears 203. The four screw rods 205 are respectively fixed to the four second gears Inside the wheel 204, four movable sleeves 206 are respectively threadedly connected to the outside of the four screw rods 205, and the four hinged rods 207 are respectively hinged to the upper surfaces of the four movable sleeves 206 through hinge shafts. The front and rear sides of the two U-shaped seats 212 are threadedly connected to the front and rear sides of the base plate 1 through bolts. The lifting assembly includes four mounting plates 208, four fixed columns 209, four sleeves 210 and a limit frame 211. The four mounting plates 208 are respectively fixed to the front and rear sides of the base plate 1 by bolts, and the four fixed columns 209 are respectively vertically fixed to the inside of the four mounting plates 208.

The four screw rods 205 are rotatably connected between the opposite sides of the U-shaped seats 212 on the left and right sides through bearings. The front and rear hinge rods 207 are respectively located on the front and rear sides of the bottom plate 1. Two connecting rods are fixed between the front and rear movable sleeves 206. The logistics goods for logistics storage are placed on the upper surface of the bottom plate 1, and then the handle is turned to make the movable rod 202 drive the two first gears 203 Rotate to make the front and rear side screw rods 205 start to rotate. The thread directions of the left and right side screw rods 205 are the same. The cross-sectional shape of the limit frame 211 is a rectangle. The front and rear side hinged rods 207 are respectively hinged to the outside of the front and rear side sleeves 210 through hinge shafts on one side away from the front and rear side movable sleeves 206.

At this time, since two connecting rods are fixed between the front and rear side movable sleeves 206, the rotation of the front and rear side movable sleeves 206 is restricted, so that the front and rear side movable sleeves 206 push the front and rear side hinged rods 207 respectively, so that the limit frame 211 can adjust the height up and down to limit the goods and prevent the goods from tipping over.
[0043] (2) When transporting goods, the four groups of springs 404 and the four groups of dampers 405 are compressed and damped to reduce the impact force of the logistics cart from the ground during transportation. At the same time, since the four T-shaped columns 402 are rotatably connected to the inside of the four mounting seats 401, the direction of the logistics cart can be adjusted.
