They are suitable for transportation, distribution, storage, and processing in air logistics and are essential for modern logistics management in production and distribution companies.
[0003] Traditional air cargo containers typically have a single cavity structure, making it impossible to separate different types of items such as medicines, food, and electronic products for storage. After transportation, they require manual secondary sorting, which is time-consuming and labor-intensive. Furthermore, the simple sealing structure of the lid makes them prone to air leakage due to changes in air pressure during air transport. Loading and unloading also require multiple screws or clips to be turned, resulting in low operational efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an EPP aviation turnover box to solve the problems of simple internal layer structure, simple sealing structure and poor sealing performance of the cover under the existing technology.
[0005] To solve the above-mentioned technical problems, an embodiment of this utility model provides an EPP aviation turnover box, including a box body, a cover plate, and partitions. The top of the box body is provided with an opening, and the cover plate is provided at the opening of the box body. Fastening mechanisms are provided at the four bottom corners of the cover plate. Grooves are provided at the four upper corners of the box body, and the grooves are corresponding to the fastening mechanisms. Frame limiting grooves are provided on the inner wall and bottom of the box body, and limiting holes are provided in the frame limiting grooves. Partition fixing mechanisms are provided around the partitions, and the partition fixing mechanisms are snap-fitted to the limiting holes.
[0006] The fastening mechanism includes a fastening sleeve, a pressing post, and two fastening limiting blocks. The top of the fastening sleeve is fixedly connected to the cover plate.

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figure 1 , Figure 2 As shown, an embodiment of this utility model provides an EPP aviation turnover box, including a box body 1, a cover plate 2 and a partition plate 4. The top of the box body 1 is provided with an opening, the cover plate 2 is provided at the opening of the box body 1, and fastening mechanisms 3 are provided at the four corners of the bottom of the cover plate 2. The four corners of the upper end of the box body 1 are provided with grooves 11, and the grooves 11 are correspondingly provided with the fastening mechanisms 3.
[0022] The fastening mechanism 3 includes a fastening sleeve 31, a pressing post 32, and two fastening limiting blocks 33. The top of the fastening sleeve 31 is fixedly connected to the cover plate 2. A first spring 34 is fixedly installed at the bottom of the sleeve. The pressing post 32 is slidably disposed inside the fastening sleeve 31. The fastening sleeve 31 has symmetrical openings on both sides. The two fastening limiting blocks 33 slide obliquely in the openings and are hinged to the pressing post 32. Two symmetrical fastening limiting grooves 35 are also provided in the groove 11, and the fastening limiting grooves 35 are correspondingly disposed to the fastening limiting blocks 33. A limiting baffle 36 is also provided at the opening of the fastening sleeve 31. The limiting baffle 36 and the sleeve wall of the fastening sleeve 31 form a positioning cavity that engages with the fastening limiting blocks 33. During the pressing and rebounding process, the fastening limit block 33 abuts against the limit baffle 36 to prevent the fastening limit block 33 from rebounding into the fastening sleeve 31.
[0023] In this embodiment, the stroke length of the first spring 34 is slightly shorter than the length of the fastening limiting block 33, so that when the first spring 34 pushes the pressing post 32 back, it will push the fastening limiting block 33 back into the fastening limiting groove 35.
[0024] By pressing down the pressing column 32, the fastening limiting block 33 moves downward synchronously with the pressing column 32 and disengages from the fastening limiting groove 35. When the column presses close to the bottom of the fastening sleeve 31, the fastening limiting block 33 also abuts against the limiting baffle 36. At this time, the cover plate 2 of the fastening sleeve 31 can be separated from the top of the box 1, completing the separation of the cover plate 2 from the box 1. Conversely, when the sleeve cover plate 2 is inserted into the groove 11, the elastic force of the first spring 34 will cause the pressing column 32 to spring up and the fastening limiting block 33 to extend into the fastening limiting groove 35 simultaneously, thus completing the sealing of the box 1 by the cover plate 2.
[0025] The inner wall and bottom of the housing 1 are provided with frame limiting grooves 12, and limiting holes 13 are provided in the frame limiting grooves 12. The partition 4 is provided with partition fixing mechanisms 5 around its perimeter, which are snapped together with the limiting holes 13. The partition fixing mechanism 5 includes a pin 51, a pull rod 52, a second spring 53, and a connecting rod 54. The partition 4 is provided with a pin groove 55, and the pin 51 is slidably disposed in the pin groove 55. One end of the pin 51 is fixedly connected to the second spring 53, and the other end is snapped together with the limiting hole 13. The surface of the partition 4 is provided with a sliding groove 56, which communicates with the pin groove 55. The pull rod 52 slides in the sliding groove 56 and is fixedly connected to the pin 51. The connecting rod 54 is horizontally disposed in the pin groove 55 and is fixedly connected to multiple pins 51. By pulling the pull rod 52 inward, the connecting rod 54 and multiple pins 51 are driven into the pin groove 55. After aligning with the limiting hole 13, the pull rod 52 is released, so that the pins 51 and the limiting hole 13 are interlocked, completing the engagement of the partition 4 and the box 1, realizing the internal partition design of the box 1.
[0026] In this embodiment, the surface of the partition 4 is also provided with through holes 41, the diameter of which is the same as the diameter of the limiting hole 13. It should also be noted that the size of the partition 4 can be changed according to the internal partitioning and layering design of the box 1, and the through holes 41 on the partition 4 can be used for classification within the box 1.
[0027] The working principle of this utility model is as follows:
[0028] Before use, press down the pressing column 32. When the column is pressed close to the bottom of the fastening sleeve 31, the fastening limit block 33 also abuts against the limit baffle 36, separating the cover plate 2 from the box body 1. Then pull the lever 52 to align the pin 51 on the partition 4 with the limit hole 13. Release the lever 52, and the second spring 53 will engage the pin 51 with the limit hole 13. By placing multiple partitions 4, the box body 1 is divided into multiple spaces, which can store different types of items. After storing the items, put the cover plate 2 on top of the box body 1. Insert the fastening sleeve 31 on the cover plate 2 into the groove 11. Due to the elasticity of the first spring 34, the pressing column 32 will spring up, and the fastening limit block 33 will simultaneously extend into the fastening limit groove 35, thus fixing the cover plate 2 firmly to the box body 1.
[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
