Description

Technical Field

[0001] The utility model relates to the technical field of logistics distribution, in particular to a logistics turnover box convenient for stacking in a logistics distribution center. Background Technique

[0002] A logistics turnover box is a container used for transporting, storing, and sorting goods, usually made of plastic or metal materials. This kind of box usually has a solid structure and a stackable design, which is convenient for stacking and storing during the logistics process and saves space. However, there are still some defects in the existing devices; for example;

[0003] As the Chinese utility model patent with the application number CN202122030139.9 discloses a logistics turnover box convenient for stacking, which includes a turnover box assembly and a connecting assembly. The turnover box assembly includes a box body, a box cover, and a buckle. The box cover is movably connected to the box body, the buckle is arranged on the box body, and the buckle is movably connected to the box cover. The connecting assembly includes a handle and a dovetail block. One handle is movably connected to both sides of the box body, and a stop block is fixedly connected to each handle. The dovetail blocks are evenly distributed and fixed on the bottom wall of the box body, and dovetail grooves adapted to all the dovetail blocks are formed on the upper surface of the box cover;

[0004] There are some problems with the above device. When the device is used, the length of the dovetail groove is greatly shortened through the connecting assembly, which is convenient for dovetail connection during stacking, and the dovetail block can be locked in the dovetail groove to prevent the upper stacked box body from sliding out; however, in the use of this device, the dovetail groove lacks fixation for the dovetail tenon, and the upper and lower stacked box bodies can still slide along the dovetail groove, and there is a risk of sliding and toppling after the box bodies are stacked, which has potential safety hazards.

[0005] Therefore, we propose a logistics turnover box convenient for stacking in a logistics distribution center to solve the above-mentioned problems. Content of the Utility Model
