Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a four-corner double-column stacked weighted cardboard box. Background Technology

[0002] Currently, cardboard boxes on the market often experience problems such as deformation and corner breakage when carrying heavy items, affecting packaging effectiveness and the safety of the goods.

[0003] Existing weight-bearing cardboard boxes are mostly made stronger by increasing the thickness or number of layers of cardboard. However, this increases material costs and the weight of the boxes, and takes up a lot of space when stacked, which is not conducive to transportation and storage. In addition, the traditional cardboard box stacking structure is not stable enough, and misalignment is easy to occur after stacking, which poses a safety hazard. Therefore, this device has certain shortcomings. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a four-corner double-column stacked weighted cardboard box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a four-corner double-column stacked heavy-duty cardboard box, comprising a cardboard box body and a box lid, wherein inner columns are fixedly connected to the inner sides of the four corners of the cardboard box body, and outer columns are fixedly connected to the outer sides of the four corners of the cardboard box body, and reinforcing columns are fixedly connected between the two sets of inner columns, wherein cavities are opened in the inner columns, and a reinforcing plate is fixedly connected to the top of the box lid, wherein four sets of reinforcing plates are provided, and the reinforcing plates are slidably connected in the cavities.

[0006] As a further description of the above technical solution:

[0007] The top of the box lid has a slot, and there are multiple sets of slots. The bottom of the carton body is fixedly connected to a block, and there are multiple sets of block blocks.

[0008] As a further description of the above technical solution:

[0009] The card slots correspond to the size and position of the card blocks.

[0010] As a further description of the above technical solution:

[0011] The reinforcing column is parallel to the bottom of the carton body.

[0012] As a further description of the above technical solution:

[0013] The height of the inner column is the same as the height of the carton body.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the reinforcing plate is provided with anti-slip texture.

[0016] As a further description of the above technical solution:

[0017] The outer side of the inner column is coated with a waterproof coating, which is a polyethylene (PE) coating.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, in the four-corner double-column stacked heavy-duty cardboard box, the four sets of inner columns on the inner side of the four corners of the cardboard body are used in combination with the four sets of outer columns on the outer side of the four corners, which greatly improves the load-bearing capacity of the cardboard box. While ensuring strength, it reduces the use of materials and lowers costs. In addition, the insertion of the reinforcing plate into the cavity and the setting of the reinforcing columns will enhance the compressive strength of the cardboard box body and prevent the cardboard box from deforming.

[0020] 2. In this utility model, the corresponding insertion method of the slots and blocks in the four-corner double-column stacked heavy-duty cardboard box can make the cardboard box body more stable when stacked, avoid misalignment and tipping, and improve safety. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-4 One embodiment of this utility model is a four-corner double-column stacked heavy-duty cardboard box, including a cardboard box body 1 and a box cover 2. Inner columns 3 are fixedly connected to the inner sides of the four corners of the cardboard box body 1, and outer columns 6 are fixedly connected to the outer sides of the four corners of the cardboard box body 1. A reinforcing column 5 is fixedly connected between the two sets of inner columns 3. A cavity 4 is opened in the inner column 3. A reinforcing plate 7 is fixedly connected to the top of the box cover 2. There are four sets of reinforcing plates 7. The reinforcing plates 7 are slidably connected in the cavity 4, providing more solid support.

[0029] The top of the box lid 2 has a slot 8, and there are multiple sets of slot 8. The bottom of the carton body 1 is fixedly connected to a block 9, and there are multiple sets of block 9. The slot 8 and the block 9 are corresponding in size and position. The reinforcing column 5 is parallel to the bottom of the carton body 1. The height of the inner column 3 is the same as the height of the carton body 1. The outer wall of the reinforcing plate 7 has anti-slip texture. The outer side of the inner column 3 is coated with a waterproof coating, which is a polyethylene (PE) coating, and has a better waterproof effect.
