[0002] Traditional simple wooden box packaging and transportation cannot solve the problem that these high-tech products cannot be effectively protected during long-distance transportation and have poor mobility. To address this problem, a new packaging product, aviation box, has emerged as an alternative to transportation. The increasingly frequent cross-border trade has brought the use and development of aviation boxes into a golden stage, especially in the fields of stage lighting equipment, medical instruments and equipment, audio-visual system multimedia, optoelectronics industry, as well as military transportation packaging and military equipment transportation.

[0003] A Chinese patent with publication number CN214216634U discloses a portable plastic aviation box, including a box body, a partition fixedly connected to the bottom end of the box body near the center, the partition divides the box body into two storage chambers, a supporting bottom plate, and a shock-absorbing assembly. The shock-absorbing assembly includes an outer plate, and the outer plate is provided with two pieces. A fixed slide rod is fixedly connected between the two outer plates. The spring is compressed by the sliding sleeve. Since the spring has very good buffering properties, the impact force exerted on the buffer plate can be buffered and released, thereby avoiding damage to fragile goods during movement, thereby improving the convenience in actual use. However, there are still some shortcomings in the existing device. When carrying the aviation box, it is necessary to lift it as a whole, but it has a certain mass. Carrying it for a long time can easily cause arm soreness. Therefore, a person skilled in the art provides a portable plastic aviation box to solve the problems raised in the above background technology. Utility Model Content
