This utility model discloses a license plate packaging box, belonging to the field of packaging materials technology. It includes a lower shell and an upper shell, with the upper shell fastened to the inner upper part of the lower shell. The lower shell includes a bottom plate. A first folding portion is provided on the upper part of the long side of the bottom plate, and a first adhesive portion is provided on the side of the first folding portion near the bottom plate. A second folding portion is provided on the upper part of the short side of the bottom plate, and a second adhesive portion is provided on the side of the second folding portion near the bottom plate. Both the first and second adhesive portions are adhered to the bottom plate. The first folding portion, the second folding portion, and the upper shell are all hollow. This utility model effectively achieves omnidirectional positioning of the license plate, perfectly meets the requirement of "avoiding vibration of the license plate without using non-degradable materials," and effectively ensures stability during the mailing process.

The invention discloses a U-shaped automatic container wharf maintenance monitoring device, and belongs to the technical field of wharf monitoring equipment.The U-shaped automatic container wharf maintenance monitoring device comprises a bottom plate, an outer sleeve is fixed to the side face of the top end of the bottom plate, an inner supporting rod is slidably connected into the outer sleeve, a placing plate is fixed to the top end of the inner supporting rod, and a surrounding plate is arranged on the side face of the top end of the placing plate; an elastic clamping assembly is arranged in the surrounding plate, an elastic supporting assembly is arranged at the bottom of the surrounding plate, and an adjusting and moving assembly is arranged on one side of the outer sleeve. The maintenance monitor in the surrounding plate is elastically wrapped and clamped through the expanded clip assembly, shaking of the maintenance monitor is effectively reduced, the height position of the containing plate can be adjusted through the adjusting and moving assembly, and then the height position of the maintenance monitor is adjusted; the bottom of the maintenance monitor has certain shock resistance through the arranged elastic supporting assembly, the overall shock resistance effect of the maintenance monitor is further improved, the accuracy of monitoring result data is improved, and meanwhile the service life of the maintenance monitor is prolonged.
