  • Patent number: 9758297
    Abstract: The invention provides an adjustable tilting packaging box for liquid crystal module. The first solution includes: box, support rack for carrying liquid crystal module, supporting rack being connected to box bottom through first support element. First support element includes at least a first adjustment mechanism, connected to side of support rack; wherein, first adjustment mechanism including: a first support pillar, a resilient element and a positioning element. First support pillar is retractably connected to box bottom through resilient element; first support pillar is disposed with resilient buckle matching positioning element to realize multi-level rising and lowering of first support pillar. Through tilt angle of support rack making PCB located at lower end of leaning, the weight of PCB prevents PCB from folding up to cause crease in COF or damage to glass during bumpy transportation.
