Internal folding type overlapped and reused logistics box

The invention discloses an internal folding type overlapped and reused logistics box which is the logistics box provided with a novel structure and applied in the logistics field. The logistics box adopts plastic (not paper) material as the matrix, and the structure of the original plastic material fixed box body is changed, so that the side faces and the bottom surface (or other faces) of the boxbody are connected through a movable joint, and the side faces are freely folded inwards without constraint; and when the box body is loaded, under the constraint of an ectopic barb and a tenon lockcatch, a side panel can be firmly perpendicular to the bottom surface, and the logistics box is not different from the fixed box body when being used. When the box body is no-load, the logistics box can be conveniently folded inwards as long as being in contact with the constraint of the ectopic barb and the tenon lock catch, so that the side panel can be overlapped on a bottom panel orderly and densely, space occupation i
