And a bottom plate assembled in the enclosed frame.

The rod body is connected to an L-shaped angle iron.

Each of the through holes described above is a multi-angled plum blossom through hole.

The bottom end of the screw of the caster is provided with a positive polygonal member, and the fixed member is located at the top end of the wheel carrier.

The inner bonding plate is configured as a plate body which is bent in a meander shape.

Another type of cargo truck structure comprises: a frame which is made up of four rods, wherein each corner end of the rod body is provided with a continuous perforation and overlap each other; a plurality of The vertical pipe is provided with a slab-shaped plate body in one side plate body of the vertical pipe, and the connected plate body can be bent into a horizontal inner inner joint plate, and the bent plate body opening portion is Forming a hole, and the center of the inner plate is provided with a coupling hole; a plurality of casters are arranged on the top of the wheel body of the caster, and a screw extends upwardly, and the top end of the screw is stretched over the corresponding frame The through hole, the joint hole of the joint plate in the vertical pipe, and a fastener is locked; and a bottom plate is assembled in the surrounding frame.

Therefore, according to the technical means of the present invention, the functions that can be obtained by the present invention are briefly described as follows:

1. The structure of the new cargo truck is provided with the through holes respectively at the lap joints of the corner ends of the rod body, and then the corresponding screws which are corresponding to each other and overlap each other are respectively penetrated by the screws on the four casters. The hole allows the through hole of the rod body to be fixed on the fixing member of the caster, so that the frame of the novel freight truck can achieve rapid assembly efficiency.

2. The structure of the new cargo truck has a hole in one side of the standpipe, and a bent inner joint plate is arranged inside the standpipe to allow the screw at the top end of each caster to be stretched and A fastener is locked to achieve a low-cost pallet truck.
