1. Field of the Invention
The present invention relates to the field of packaging, and in particular to a package box of liquid crystal display module.
2. The Related Arts
It is inevitable that a liquid crystal display module may be impacted by external forces and falling during the shipping thereof. To well protect the liquid crystal display module, it is desired to add a cushioning device in a package box to spread impact forces induced by external forces and absorb the impact energy of falling.
A conventional package box of liquid crystal display module is illustrated in FIG. 1. The package box comprises a box body 100, a bottom cushioning structure 300, and a top cushioning structure 500. The bottom cushioning structure 300 comprises a cushioning bottom board 302, two cushioning side boards 304 that are mounted on the cushioning bottom board 302 and arranged at two ends of the cushioning bottom board 302, and three positioning cushioning boards 306 that are mounted on the cushioning bottom board 302 and arranged, in a spaced manner, between the two cushioning side boards 304. The two cushioning side boards 304 are both provided with a plurality of spaced receiving slots 305. The three positioning cushioning boards 306 are all provided with a plurality of positioning slots 307 corresponding to the receiving slots 305. The top cushioning structure 500 that is used in combination with the bottom cushioning structure 300 has a structure corresponding to that of the bottom cushioning structure 300.
To set up, the bottom cushioning structure 300 is first positioned in the box body 100.
