[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, a special carton for fruits with a fresh-keeping function, comprising a box body 1, side plates 2, a fresh-keeping box 3, a placement box 4 and a buffer device. The side plates 2 are foldably installed at the top edge of the box body 1. A support plate 5 is installed at the bottom inside the box body 1. A number of groups of symmetrically designed vertical plates 6 are installed on the bottom wall of the support plate 5. The bottom ends of the vertical plates 6 are fixedly connected to the bottom wall inside the box body 1. The fresh-keeping box 3 is installed at the central position inside the box body 1. A number of square grooves 7 penetrating through the fresh-keeping box 3 are evenly opened on the side wall of the fresh-keeping box 3. The fresh-keeping box 3 divides the box body 1 into four placement areas 8. A number of the placement boxes 4 can be stacked in the placement areas 8. A placement groove 9 is opened at the top of the placement box 4. The buffer device includes sliders 10, fixed rods 11, springs 12 and buffer frames 13. Two groups of symmetrically designed rectangular grooves 14 are horizontally opened on the two side walls of the placement box 4 away from the fresh-keeping box 3. The fixed rods 11 are fixedly installed in the two groups of rectangular grooves 14. Springs 12 are sleeved on the outer walls of the fixed rods 11. Sliders 10 are slidably installed at the corresponding ends of the two groups of fixed rods 11. A buffer frame 13 is jointly connected to the sides of the two sliders 10 away from the rectangular grooves 14. In this embodiment, during use, the inner cavity of the box body 1 is separated from the bottom wall of the box body 1 by the support plate 5. A number of vertical plates 6 installed on the bottom wall inside the box body 1 play a role of spacing and stable support for the support plate 5, so as to ensure the safety of the fruits stored in the inner box body 1 to the greatest extent. A number of frozen ice bags or other fresh-keeping agents are placed in the fresh-keeping box 3. Then the fruits to be fresh-kept are placed in the placement box 4. Then the placement boxes 4 are stacked in each placement area 8 in turn. Then the box body 1 is sealed by the side plates 2. The cold air emitted by the ice bags will evenly enter the box body 1 through the square grooves 7, playing a role of fresh-keeping for the fruits. During the transportation of the box body 1, the side wall of the box body 1 is most likely to be impacted. When impacted, the side wall of the box body 1 will contact the buffer frame 13. The buffer frame 13 will drive the two sliders 10 to slide towards the ends of the two fixed rods 11 away from each other. Under the support of the springs 12, the sliders 10 can quickly slide back into place. The springs 12 can undergo elastic deformation to absorb and disperse these impact forces. This characteristic of the springs 12 enables the entire buffer device to effectively reduce the direct impact of the outside on the fruits in the placement box 4 and provide safety protection for the fruits in the placement box 4.

[0026] In actual use, it is further convenient to support the stacked placement boxes 4. In this embodiment, support columns 15 are fixedly installed at the four corners of the top of the placement box 4, and support blocks 16 are fixedly installed at the top of the support columns 15. Support grooves 17 are opened at the four corners of the bottom end of the placement box 4, and the support grooves 17 are adapted to the support blocks 16. When multiple groups of placement boxes 4 are stacked, the support columns 15 support their support blocks 16, and the support blocks 16 are adapted to the support grooves 17 opened on the bottom wall of the placement box 4 above them, which can not only provide stable stacking support for the placement boxes 4, but also accurately position the placement of the placement boxes 4.

[0027] During actual use, the fresh-keeping box 3 is further insulated. In this embodiment, a pressure plate 18 is movably installed at the top of the fresh-keeping box 3, and a fresh-keeping cover 19 is installed at the bottom of the pressure plate 18. The fresh-keeping cover 19 is adapted to the fresh-keeping box 3. When the box body 1 is filled with fruits, the pressure plate 18 is placed at the top of the box body 1, and the fresh-keeping cover 19 is aligned with the fresh-keeping box 3. The top of the fresh-keeping box 3 is closed to prevent the cold air in the fresh-keeping box 3 from dissipating. The pressure plate 18 protects the top of the box body 1.

[0028] Preferably, in the present embodiment, the buffer rack 13 is an arc-shaped elastic block and the arc protrudes toward the outside of the placement box 4. As an elastic block, the buffer rack 13 can absorb and disperse external shocks and vibrations. When encountering external shocks, the arc-shaped elastic block can undergo elastic deformation, thereby effectively reducing the impact of the shock on the fruit in the placement box 4, and the arc is oriented to facilitate contact with the inner wall of the box body 1.

[0029] Preferably, in this embodiment, the pressure plate 18 is elastically configured to effectively disperse and reduce the pressure inside the box 1. The elastic pressure plate 18 helps to reduce damage to the fruit caused by top squeezing or collision during transportation, thereby protecting the quality of the fruit and extending its shelf life.

[0030] In actual use, in order to further improve the heat preservation effect of the fresh-keeping box 3, in this embodiment, the fresh-keeping cover 19 and the fresh-keeping box 3 are both provided with a heat preservation layer, which is convenient for keeping the ice bag in the fresh-keeping box 3 warm and slowing down the melting speed of the ice bag.

[0031] Preferably, in the present embodiment, the fresh-keeping box 3 and the fresh-keeping cover 19 are both designed in a "cross" shape. The cross-shaped design can make full use of the space in the box body 1. Compared with other shapes, its structural stability is higher and it is not easy to shift or tip over during transportation, thereby ensuring that the fresh-keeping box 3 can continuously and effectively provide a fresh-keeping effect for the fruit.

[0032] In the actual use process, to further improve the support strength of the vertical plate 6, in this embodiment, each group of the vertical plates 6 is designed to be relatively inclined. Each group of relatively inclined vertical plates 6 can form a stable triangular structure with each other. Structurally, compared with traditional vertical components, its lateral stability performance is better.

[0033] To illustrate in detail the possible application scenarios, technical principles, specific implementable solutions, achievable purposes and effects of the present application, the following will be described in detail with reference to the specific examples listed and in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, so they are only examples and cannot be used to limit the protection scope of the present application.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
