Description

technical field [0001] The invention relates to a packing box and a trolley with an overturning guide mechanism installed inside the box body of the packing box. Background technique [0002] Packaging boxes are suitable for domestic or export packaging of various goods and products, and are economical. With the globalization of goods circulation, the use of packaging boxes is becoming more and more frequent, and the types of packaging boxes are also increasing. [0003] Yet all there are some shortcomings in existing packing case: [0004] First, as disclosed in the packing box of Chinese patent CN200620039747.9 and the packing box disclosed in Chinese patent CN200620129949.2, these types of packing boxes have not yet installed tackles inside, so that the existing packing boxes are manually loaded and unloaded. Handling, which in turn makes the loading and unloading of goods time-consuming, laborious, inefficient, and difficult to load and unload; [0005] Second, there i...

Problems solved by technology

[0004] First, as disclosed in the packing box of Chinese patent CN200620039747.9 and the packing box disclosed in Chinese patent CN200620129949.2, these types of packing boxes have not yet installed tackles inside, so that the existing packing boxes are manually loaded and unloaded. Handling, which in turn makes the loading and unloading of goods time-consuming, laborious, inefficient, and difficult to load and unload;

[0005] Second, there is no protective device inside the existing packaging box, so the loaded items placed inside the packaging box are easy to slide, and the loaded items inside the packaging box are easily damaged during the transportation of the packaging box;

[0006] Third, the existing packaging boxes are not easy to stack, and when multiple packaging boxes are stacked together, they are easy to collapse
