Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a weighted carton with four-corner protections. Background Art

[0002] Large-volume heavy-duty cartons are often used to package and transport heavy products or large quantities of goods. Large-volume heavy-duty cartons are generally composed of a main box body and a box cover. Since the main box body generally stores large-volume items and is relatively heavy overall, a forklift pallet will be set at the bottom of the main box body to facilitate the forklift to insert and lift the goods for transportation and loading in the later stage.

[0003] Since the main box is heavy overall, protective support blocks are generally set at the four corners of the forklift pallet to improve the bottom protection effect.

[0004] Due to the long-term use of the protective support blocks at the four corners of the forklift pallet at the bottom of the main box, they are prone to wear, aging, and even deformation, which makes it easy for the large-volume weighted carton to tilt when placed. At this time, it is necessary to disassemble and replace the protective support blocks that are worn, aged, and deformed. However, the protective support blocks at the four corners of the forklift pallet of the existing large-volume weighted cartons are mostly installed with bolts. Each bolt needs to be removed with a screwdriver, which is very troublesome and greatly reduces the convenience of individually disassembling and replacing the protective support blocks at the bottom of the large-volume weighted carton.

[0005] In addition, the bottom forklift pallet needs to support the main box body above, but the overall structural stability of the bottom forklift pallet of the existing large-volume weighted cartons is low and easy to deform, which greatly reduces the overall supporting structural stability of the forklift pallet for large-volume weighted cartons.

[0006] The above problems are widespread and urgently need to be improved. Utility Model Content

[0029] After the protective support block 4 is installed and inserted into the limiting slot 20, the installation limiting stability can be improved.

[0030] In detail, an embedded block 12 is embedded in the bottom of the main box body 1, and a mounting bolt 21 is inserted on the forklift pallet 2. The mounting bolt 21 is threadedly connected to the embedded block 12. The bottom end surface of the preset nut of the mounting bolt 21 is flush with the bottom end surface of the inner groove of the plug-in plate through-hole 22. The embedded block 12 is made of metal, and a screw groove is preset on the embedded block 12. The forklift pallet 2 can be stably installed on the main box body 1 through the preset screw groove and the mounting bolt 21.

[0031] Furthermore, the screw rod 61 passes horizontally through the forklift pallet 2 and is threadedly connected to the screw hole 42, the connecting block 6 is inserted in the inner groove 41, and the hook ring 62 is arranged on the inner end face of the connecting block 6. The side cross-section of the connecting block 6 and the inner groove 41 is a circular structure, which facilitates the connection block 6 to rotate in the inner groove 41.

[0032] Furthermore, the protective support block 4 is made entirely of carbon fiber material, which has high strength, does not deform, and is lightweight. In addition, the four protective support blocks 4 provide effective protective support for the four lower corners of the forklift pallet 2 .

[0033] The lower end surface of the protective support block 4 is lower than the lower end surface of the forklift pallet 2. The plug-in plate opening 22 and the stepped groove 23 are both longitudinally through-type, so that the two plug-ins of the forklift can be directly inserted into the plug-in plate opening 22, so as to facilitate the transportation of the main box body 1 to the shelf at a later time.
