[0029] This utility model discloses a flattened, automatically formed hand-held packaging box.

[0030] Example 1

[0031] Reference Figure 1-5A flattened, automatically formed portable packaging box includes a lower box body 1 and an upper box body 2. The upper surface of the lower box body 1 has an annular groove 9, and the upper box body 2 is slidably inserted into the annular groove 9. The outer walls of both the upper box body 2 and the lower box body 1 are covered with a waterproof membrane to improve the waterproof performance of the packaging box. The cross-sections of both the upper box body 2 and the lower box body 1 are rectangular, allowing the upper box body 2 to slide stably. The bottom of the lower box body 1 has a first crease 10, and the four sides of the lower box body 1 have second creases 11. The top of the upper box body 2 has a third crease 12 parallel to the first crease 10, and the four sides of the upper box body 2 have fourth creases 13. Mounting blocks 3 are fixedly installed on both sides of the lower box body 1, and carrying ropes 4 are fixedly installed on the outer side of the mounting blocks 3. The carrying ropes 4 on both sides are made of nylon rope, making them more durable.

[0032] Example 2

[0033] Reference Figure 1-5 The upper end of the lower box 1 is provided with limiting mechanisms on both sides to restrict the upward movement of the upper box 2. The limiting mechanisms include locking blocks 14 and elastic L-shaped rods 16. Multiple locking blocks 14 are fixedly arranged on both sides of the upper box 2 from top to bottom. Fixed rods 15 are fixedly arranged on both sides of the upper end of the lower box 1. The elastic L-shaped rods 16 are fixedly arranged on the side of the fixed rods 15 away from the lower box 1. The inner side of the upper end of the elastic L-shaped rods 16 abuts against the upper surface of the corresponding locking blocks 14. The lower surface of the locking blocks 14 and the upper end of the elastic L-shaped rods 16 are both provided with inclined surfaces, so that the locking blocks 14 can squeeze the elastic L-shaped rods 16 away from the lower box 1.

[0034] Example 3

[0035] Reference Figure 1-5 A space adjustment mechanism is provided between the interior of the lower box 1 and the upper box 2. The space adjustment mechanism includes a first adjustment plate 7 and a second adjustment plate 8. The first adjustment plate 7 is slidably disposed inside the lower box 1, and the second adjustment plate 8 is slidably disposed inside the upper box 2. A groove is provided on the top of the first adjustment plate 7, and the lower end of the second adjustment plate 8 is slidably inserted into the groove. Movable strips 5 are fixedly provided at opposite ends of the first adjustment plate 7 and the second adjustment plate 8. Both ends of the movable strips 5 abut against the inner walls of the corresponding lower box 1 and upper box 2, so that the first adjustment plate 7 and the second adjustment plate 8 can slide stably.
