Description

Technical Field

[0001] This utility model belongs to the field of durian transportation technology, specifically relating to a protective device for transporting durians. Background Technology

[0002] Durian is hailed as the "King of Fruits," but its unique hard, spiky shell, delicate and fragile flesh, strong odor, and crucially, its post-ripening characteristics make its transportation an extremely challenging task. Because vibrations during transport significantly impact durians, shock-absorbing protection is necessary. Furthermore, as durians are climacteric fruits, they continuously produce ethylene after harvesting, accelerating their ripening and aging. To suppress respiration, slow the ripening process, and ensure they arrive at their optimal consumption condition, refrigerated transport is required. To ensure proper air circulation, ventilation holes need to be created on the sides of the protective boxes. However, when the boxes are stacked close together, and the distance between boxes increases or decreases with transport, the ventilation holes can easily be blocked, affecting air circulation, reducing refrigeration effectiveness, and negatively impacting the quality of the durians.

[0019] Please see Figures 1-5The present invention provides the following technical solution: a protective box 1, the protective box 1 having a foam base 11 inside, a box cover 2 detachably connected to the top of the protective box 1, a foam pad 23 at the bottom of the box cover 2, alignment rods 14 on both sides of the protective box 1, two through holes 21 on the box cover 2, the alignment rods 14 being movably connected to the through holes 21, a limiting block 141 threadedly connected to the top of the alignment rods 14, a base plate 3 at the bottom of the protective box 1, two through holes 31 on the base plate 3, the limiting block 141 being movably connected to the through holes 31, ventilation holes 12 on both sides of the protective box 1, two ventilation grooves 22 on the box cover 2, and two ventilation grooves 32 on the base plate 3.

[0020] This implementation plan includes a protective box 1 with an open top, allowing durians to be placed inside. The inside of the protective box 1 is equipped with a foam base 11, which cushions and absorbs shocks, reducing the risk of damage during transport. A lid 2 is detachably connected to the top of the protective box 1, sealing the durian inside. There is a gap between the inside of the lid 2 and the outside of the protective box 1. A foam pad 23, made of the same material as the foam base 11, provides additional protection for the durian. The protective box 1 has alignment rods 14 on both sides. The alignment rods 14 are vertical and there is a gap between them and the protective box 1. The box cover 2 has two through holes 21. When the box cover 2 is placed on the protective box 1, the alignment rods 14 need to be inserted into the inside of the through holes 21. The alignment rods 14 and the through holes 21 are movably connected. Through the connection between the alignment rods 14 and the through holes 21, the box cover 2 can be limited to prevent it from shifting. The top of the alignment rods 14 is threadedly connected to a limit block 141. After the box cover 2 is connected to the alignment rods 14, the limit block 141 is connected to the top of the alignment rods 14, which limits the box cover 2 and improves the connection stability between the box cover 2 and the protective box 1. To prevent the lid 2 from separating from the protective box 1 during transportation and handling, ensuring the protection of the durian, the bottom of the protective box 1 is equipped with a bottom plate 3, which is fixedly connected to the protective box 1. The bottom plate 3 has two through holes 31, symmetrically positioned and located below the alignment rod 14. A limiting block 141 is movably connected to the through holes 31. When two protective boxes 1 are stacked vertically, the bottom plate 3 of the upper protective box 1 will be positioned on the top lid 2 of the lower protective box 1. By allowing the lower limiting block 141 to enter the inner side of the upper through hole 31, the two protective boxes 1 can be connected, improving the stability when multiple protective boxes 1 are stacked. Both sides of the protective box 1 have... Ventilation holes 12 are positioned opposite each other, allowing cold air to circulate between the inside and outside of the protective box 1. Two ventilation slots 22 are provided on the lid 2, and two ventilation slots 32 are provided on the base plate 3. Ventilation slots 22 and 32 are of the same size. These slots prevent interference between the lid 2 and the base plate 3 in the vertical flow of cold air, allowing cold air to circulate between the protective boxes 1, ensuring effective refrigeration of the durian during transportation. The protective box 1, foam base 11, lid 2, and foam pad 23 provide shock absorption, cushioning, and puncture protection for the durian during transportation, reducing the risk of damage.The ventilation holes 12, ventilation slot 1 22, and ventilation slot 2 32 allow cold air to circulate inside and outside the protective box 1, as well as between several protective boxes 1, ensuring the refrigeration effect on the durians during transportation. Furthermore, the connection between the alignment rod 14 and the box lid 2 and bottom plate 3 improves the stability of stacking several protective boxes 1, further reducing the impact of transportation on the durians.

[0021] The protective box 1 has fixing blocks 13 on both sides, and the alignment rod 14 is fixedly connected to the top of the fixing blocks 13; the positions of the two fixing blocks 13 are symmetrical to each other, and the top of the alignment rod 14 is higher than the protective box 1.

[0022] The top of the foam base 11 is concave, and the bottom of the foam pad 23 is arc-shaped. The foam pad 23 is perpendicular to the position of the foam base 11. By placing the durian in the concave part of the foam base 11 and then placing the foam pad 23 on top of the durian, the durian can be protected by the foam base 11 and the foam pad 23.

[0023] The protective box 1 is provided with handles 15 on both sides. The handles 15 and the alignment rod 14 are located on different sides of the protective box 1. The handles 15 are fixedly connected to the protective box 1, and the protective box 1 can be easily moved through the two handles 15.

[0024] The dimensions of the through hole 21 match those of the alignment rod 14, and the dimensions of the through hole 31 match those of the limiting block 141. By inserting the alignment rod 14 into the inside of the through hole 21, the cover 2 can be limited by the alignment rod 14.

[0025] The position of the alignment rod 14 is perpendicular to the position of the second through hole 31, and the position of the first vent groove 22 is perpendicular to the position of the second vent groove 32. By connecting the second through hole 31 on the other protective box 1 to the limiting block 141, the stability between the two protective boxes 1 can be improved.

[0026] The handle 15 and the vent 12 are located on the same side of the protective box 1. The inner diameter of the through hole 21 is smaller than the outer diameter of the limiting block 141. There is a gap between the outer side of the protective box 1 and the inner side of the box cover 2, so as to avoid the box cover 2 from blocking the vent 12 and affecting the ventilation. After the box cover 2 is connected to the alignment rod 14, the limiting block 141 is connected to the alignment rod 14, so that the box cover 2 can be limited by the limiting block 141.

[0027] The working principle and usage process of this utility model are as follows: When using it, firstly, the durian needs to be placed in the recess of the foam base 11, and then the box lid 2 is placed on the protective box 1. At the same time, the two alignment rods 14 need to be inserted into the inner side of the two through holes 21 respectively. Then, the limiting block 141 is connected to the alignment rods 14, thereby fixing the position between the box lid 2 and the protective box 1. After several protective boxes 1 are packaged, by connecting the through hole 2 31 to the limiting block 141, the purpose of stacking several protective boxes 1 can be achieved. By connecting the alignment rods 14 to the through holes 21 and 31, the stability of several protective boxes 1 when stacked can be improved. And through the ventilation holes 12, ventilation grooves 22 and 32, cold air can circulate inside and outside the protective box 1 and between several protective boxes 1.
