Packing boxes of liquid crystal panels

Abstract

The present disclosure relates to a packing box for carrying liquid crystal panels. The packing box includes an outer body and two bearing trays received within the outer body. Each of the bearing trays includes a body and a plurality of clips arranged periodically. The body includes a first surface and a second surface back to the first surface. The clip protrudes from the first surface toward the second surface. The clip includes a recess portion on a top portion of the first surface and a protrusion portion on the second surface. A hub is arranged on a bottom of the recess portion, and the hub extends toward an internal of the protrusion portion. When the two bearing trays are stacked, the protrusion portion of the bearing trays on a top layer inserts into the hub of the other bearing tray to abut against a wall of the hub.
