[0022] The strengthening mechanism 16 includes a protective block 1601, a support plate 1602, a support block 1603, a stabilizing groove 1604, and a strengthening plate 1605. A protective block 1601 is fixedly connected to the outer surface of the outer box body 1, a support plate 1602 is fixedly connected to the lower surface of the outer box body 1, a support block 1603 is fixedly connected to one side surface of the support plate 1602, a stabilizing groove 1604 is formed on the inner surface of the outer box body 1, and a strengthening plate 1605 is fixedly connected to the inner surface of the stabilizing groove 1604. Through the arrangement of the protective block 1601, the support plate 1602, the support block 1603, the stabilizing groove 1604, and the strengthening plate 1605, during use, the protective block 1601 fixedly connected to the outer surface of the outer box body 1 plays a key anti-collision protection role, protecting the four corners of the outer box body 1 and making it not easily deformed. The support plate 1602 and the support block 1603 under the outer box body 1 cooperate with each other to enhance the support strength of the bottom of the lunch box. The stabilizing groove 1604 and the strengthening plate 1605 fixedly connected to its inner surface provide an important reinforcement effect for the overall structure of the lunch box. The components in the strengthening mechanism 16 cooperate with each other to protect the lunch box from external damage, improve the durability of the lunch box, and through maintaining the structural integrity and stability of the lunch box, make the heat preservation effect of the lunch box more stable.
[0023] Furthermore, there is a certain gap between the outer box body 1 and the inner box body 2, forming an air heat insulation layer. The inner box body 2 is fixedly connected to the fixing block 10. Through the arrangement of the fixing block 10 and the inner box body 2, during use, the inner box body 2 is fixedly connected to the fixing block 10, providing stability for the entire lunch box, and further maintaining the uniformity and effectiveness of the air heat insulation layer, making the heat preservation effect more stable.
[0024] Furthermore, multiple groups of waterproof plates 4 are arranged on the inner surface of the heat insulation layer 3, and multiple groups of placement grooves 6 are arranged at equal intervals on the surface of the base 5. Through the arrangement of the waterproof plates 4, during use, the multiple groups of waterproof plates 4 can effectively prevent moisture from penetrating into the heat insulation layer 3 and being affected by moisture, thereby maintaining the stability of the heat preservation performance of the lunch box.
[0025] Furthermore, the inner wall size of the placement groove 6 matches the outer wall size of the placement block 7, and multiple groups of placement blocks 7 are arranged at equal intervals on the lower surface of the divided lunch box 8. Through the arrangement of the placement groove 6 and the placement block 7, during use, the design that the inner wall size of the placement groove 6 matches the outer wall size of the placement block 7 makes the sliding operation of the placement block 7 in the placement groove 6 smoother, making the installation of the divided lunch box 8 more convenient.
[0026] Furthermore, multiple sets of partitioned lunch boxes 8 are provided. The inner wall size of the fixed block 10 matches the outer wall size of the rotating shaft 11. Two sets of limiting pieces 12 are provided at both ends of the rotating shaft 11, and two sets of rotating blocks 13 are provided. Through the arrangement of the limiting pieces 12, during use, the limiting pieces 12 can limit the movement range of the rotating shaft 11 in the axial direction, enabling the rotating shaft 11 to rotate within a stable range and ensuring the smooth opening and closing of the box cover 14.
[0027] Furthermore, multiple sets of protective blocks 1601 are provided at the four corners of the outer box body 1, and multiple sets of support plates 1602 are arranged at equal intervals on the lower surface of the outer box body 1. Through the arrangement of the protective blocks 1601, during use, the multiple sets of protective blocks 1601 distributed at the four corners enhance the overall structural stability of the outer box body 1, prevent the outer box body 1 from deforming due to excessive local pressure, and ensure the stability of the overall structure of the lunch box.
[0028] Furthermore, multiple sets of support blocks 1603 are arranged at equal intervals on the lower surface of the outer box body 1, and the reinforcing plate 1605 is composed of multiple V-shaped plates. Through the arrangement of the reinforcing plate 1605, during use, the reinforcing plate 1605 increases the overall structural strength and rigidity of the outer box body 1. The V-shaped plates have good mechanical properties. When subjected to external forces, they can effectively disperse and bear the stress. When the outer box body 1 is subjected to lateral extrusion or torsional force, the V-shaped plates can transmit and disperse these forces in different directions, enabling the outer box body 1 to better resist deformation.
[0029] Working principle: When food is placed in the lunch box, first, the heat preservation layer 3 inside the inner box body 2 plays a major heat preservation role, reducing the heat transfer to the outside. The air heat insulation layer between the inner box body 2 and the outer box body 1 further prevents the conduction of heat. At the same time, the heat insulation board 15 under the box cover 14 prevents heat from losing from the top, and the waterproof board 4 prevents the moisture in the food from penetrating into the heat preservation layer 3 and affecting the heat preservation performance. Users can install and disassemble the partition lunch box 8 according to their needs to achieve the classified placement of food. The design that the inner wall size of the placement groove 6 matches the outer wall size of the placement block 7 makes the sliding operation of the placement block 7 in the placement groove 6 smoother, making it more convenient to install the partition lunch box 8. When the box cover 14 needs to be opened, the box cover 14 can be lifted. The rotating shaft 11 rotates smoothly in the fixed block 10, and the limiting pieces 12 limit the axial movement at both ends of the rotating shaft 11 to ensure that the rotating shaft 11 rotates within a stable range, making the opening and closing actions of the box cover 14 accurate and smooth. When the box cover 14 is closed, it can fit tightly with the outer box body 1 to ensure the sealing of the lunch box and further enhance the heat preservation effect. The protective block 1601 fixedly connected to the outer surface of the outer box body 1 plays a key anti-collision protection role, protecting the four corners of the outer box body 1 and making it not easy to deform. The support plate 1602 and the support block 1603 under the outer box body 1 cooperate with each other to enhance the support strength of the bottom of the lunch box. The stabilizing groove 1604 and the reinforcing plate 1605 fixedly connected to its inner surface provide an important reinforcement function for the overall structure of the lunch box. The components in the strengthening mechanism 16 cooperate with each other to protect the lunch box from external damage and improve the durability of the lunch box. By maintaining the structural integrity and stability of the lunch box, each component makes the heat preservation effect of the lunch box more stable.
