Description

TECHNICAL FIELD

[0001] The utility model relates to packing tool technical field, specifically, relate to a full paper heavy packing box. BACKGROUND

[0002] In the packing tool technical field, especially for the packing of heavy articles, traditional packing boxes are often made of wood, plastic or metal materials to ensure sufficient strength and load-bearing capacity. However, these materials not only have high costs, but also may cause adverse effects on the environment during production and processing, such as consumption of wood resources, difficulty in degradation of plastic waste, etc. With the enhancement of environmental awareness and the promotion of the concept of sustainable development, it has become an urgent demand in the industry to find an environmentally friendly, economical and sufficiently strong packing material.

[0003] As a new type of environmentally friendly packing solution, full paper packing boxes have gradually attracted market attention. Compared with traditional materials, paper has the advantages of being renewable, easily degradable, and relatively low cost. However, to apply paper to the heavy packing field, the problems of load-bearing capacity and structural stability must be solved. The internal stability is poor during transportation, and the internal components are easily separated by vibration. Therefore, developing a full paper heavy packing box that is both environmentally friendly and has sufficient strength and stability has become an important research direction in the packing tool technical field. SUMMARY

[0004] The utility model aims at providing a full paper heavy packing box to solve the problem of poor internal stability during transportation and easy separation of internal components caused by vibration when paper is applied to the heavy packing field, as mentioned in the background art.

[0006] As a preferred embodiment, end sockets are provided on the top of the bottom plate close to the end plates, end insertion plates are installed on the bottom of the end plates, and the end sockets and the end insertion plates are inserted and matched.

[0007] As a preferred embodiment, side sockets are provided on the top of the bottom plate close to the side plates, side insertion plates are installed on the bottom of the side plates, and the side sockets and the side insertion plates are inserted and matched.

[0008] Preferably, weight-reducing holes are provided on both sides of the middle portion of the bottom plate.

[0009] Preferably, the side panels, side plates and end plates are all provided with direction marks.

[0010] Preferably, a support plate is installed on the outer side of the middle portion of the side plate, and the bottom of the support plate abuts against the bottom plate.

[0011] Preferably, the clamping mechanism includes a fixed sleeve, a slot is provided on the inner side of the fixed sleeve, a movable block is inserted into the slot, a spring is installed at the bottom end of the movable block, and the outer end of the movable block is plugged into the assembly hole.

[0012] Preferably, a hand hole is provided in the middle of the bottom plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This all-paper heavy-duty packaging box features a stable internal structure by installing a bottom plate on the bottom surface of the box body, and mounting side and end panels on the bottom plate. In particular, the interlocking fit between the end and side panels and the bottom plate (e.g., end latches and end inserts, and side latches and side inserts), as well as the tightening mechanism that secures the end panels, effectively improves the overall stability and load-bearing capacity of the box, preventing internal components from becoming detached due to vibration during transport.

[0015] The choice of an all-paper material minimizes the environmental impact of this packaging box during production and disposal. Paper, a renewable resource, easily degrades upon disposal, meeting the requirements of environmental protection and sustainable development. Compared to traditional wood, plastic, or metal packaging boxes, this all-paper packaging box offers significant material cost advantages. Furthermore, its structural design takes into account ease of production and assembly, further reducing manufacturing costs.

[0016] A hand hole in the center of the base facilitates handling and moving of the boxes. Directional markings on the side and end panels help maintain proper orientation during handling and stacking, improving operational efficiency. Lightening holes on both sides of the center of the base reduce the overall weight of the boxes while maintaining sufficient strength and stability, achieving a balance between lightweight and load-bearing capacity.
