[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5 As shown, the embodiment of the utility model includes a box body 1 and a flap 2 arranged on the outer edge of the box body opening, and also includes an inner box body 3 and a buffer sheet 4. Reinforcement strips 5 are provided on the four corners of the box body, and positioning grooves 6 and connecting grooves 7 are provided on the reinforcement strips. Connecting protrusions 8 that are plugged into the above-mentioned connecting grooves are provided at both ends of the buffer sheet, and the inner box body can be just inserted into the space formed between the positioning grooves on the four reinforcement strips.

[0026] When designing a corrugated box, reinforcement strips are installed at the four corners of the box body. The reinforcement strips have positioning grooves and connection grooves for connecting buffer sheets. The size of the inner box body precisely matches the positioning groove space between the reinforcement strips to ensure a secure embedding. The connection protrusions at both ends of the buffer sheet can be inserted into the connection grooves to fix the position of the buffer sheet.

[0027] After adopting the above technical solutions, the structural stability, buffering pressure resistance and flexibility of use of the carton can be enhanced.

[0028] The utility model is further configured as follows: a raised base 9 is provided at the bottom of the reinforcing strip, a first magnetic rubber sheet 10 is provided on the raised base, and a second magnetic rubber sheet 11 that attracts the first magnetic rubber sheet is provided at the bottom of the inner box.

[0029] A raised base is added at the bottom of the reinforcement strip, and a first magnetic rubber sheet is installed; accordingly, a second magnetic rubber sheet is provided at the bottom of the inner box, and the two sheets are fixed to each other by magnetic attraction. The inner box is connected to the box body by two mutually attractive magnetic rubber sheets, which increases the stability of the bottom of the carton and prevents sliding.

[0030] The utility model is further configured as follows: the buffer sheet is composed of an elastic rubber shell 12 and an air gasket 13 arranged in the elastic rubber shell.

[0031] The buffer sheet is composed of an elastic rubber shell wrapped with an air gasket. The air gasket is placed inside the rubber shell and uses the compressibility of the gas to absorb the impact force. This buffer sheet design can more effectively absorb and disperse external impacts, providing excellent shock protection for the goods, especially when encountering sudden vibrations or impacts during transportation, which can greatly reduce the risk of damage to the goods.

[0032] The utility model is further configured as follows: the cross-sections of the connecting groove and the connecting protrusion are "T"-shaped structures.

[0033] This "T"-shaped interface structure improves the connection strength between the buffer sheet and the reinforcement strip, and can prevent the components from falling off even during high-intensity handling or transportation, thus ensuring the integrity and reliability of the packaging.

[0034] The utility model is further configured as follows: the box body and the inner box body both include an outer corrugated paperboard 14, a fireproof layer 15, a heat-insulating layer 16 and an inner corrugated paperboard 17 which are sequentially arranged from the outside to the inside.

[0035] The outer corrugated cardboard, fireproof layer, thermal insulation layer and inner corrugated cardboard are laid out from the outside to the inside of the box and the inner box to build a multi-layer protection structure. This multi-layer structure not only strengthens the physical protection performance of the carton, but also improves the safety and temperature control ability of the packaging by adding the fireproof layer and thermal insulation layer, which can meet the transportation needs of a wider range of goods, especially those that are sensitive to temperature and humidity or require fire protection.

[0036] The utility model is further configured as follows: the fireproof layer is modified EPDM rubber.

[0037] The fireproof layer uses modified EPDM rubber as the fireproof layer material. Modified EPDM rubber has excellent flame retardancy and weather resistance, which can effectively prevent the spread of fire, protect the items in the box from the threat of fire, and extend the service life of the carton in harsh environments.

[0038] The utility model is further configured as follows: the thickness of the fireproof layer is 1-3 mm.

[0039] The utility model is further configured as follows: the thermal insulation layer is a corn starch-based material board with a thickness of 1-2 mm.

[0040] The insulation layer uses a 1-2mm thick corn starch-based material board. As a degradable and environmentally friendly material, corn starch-based material not only improves the eco-friendliness of the packaging, but also has good thermal insulation properties. It can effectively regulate the temperature inside the box and protect temperature-sensitive goods such as food and medicine, while responding to the requirements of sustainable development.

[0041] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
