[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 belong to the scope of protection of the present utility model.

[0024] Embodiment 1 is given by Figures 1-7 The present utility model includes a base 1. On both the left and right sides of the upper end of the base 1, short side plates 2 are movably provided. On both the front and rear sides of the upper end of the base 1, long side plates 3 are movably provided. The two long side plates 3 and the two short side plates 2 are movably inserted and arranged.

[0025] On both sides of the short side plate 2, insertion ports 4 are provided. On both sides of the long side plate 3, insertion blocks 5 are connected. The insertion blocks 5 are movably clamped with the insertion ports 4. On both sides of the upper part of the outer wall of the long side plate 3, positioning blocks 6 are connected. A positioning groove 7 is penetrated through the inside of the positioning block 6. A pull-ring locking fastener 8 is arranged inside the positioning groove 7. A locking groove 9 is opened on the upper part of the short side plate 2. The pull-ring locking fastener 8 is inserted into the locking groove 9.

[0026] On both sides of the upper end of the base 1 corresponding to the installation of the short side plates 2, short side plate slots 10 are opened. On the upper side of the inside of the short side plate slots 10, first stop blocks 11 are connected. At the lower end of the short side plate 2, a short side plate insertion block 12 is connected. On both sides of the lower part of the short side plate insertion block 12, limiting protrusions 13 are connected.

[0027] On both sides of the upper end of the base 1 corresponding to the installation of the long side plates 3, long side plate slots 14 are provided. On the upper side of the inside of the long side plate slots 14, second stop blocks 15 are connected. At the lower end of the long side plate 3, a long side plate insertion block 16 is connected. On both sides of the lower part of the long side plate insertion block 16, limiting pins 17 are connected. On the upper side of the upper part of the long side plate insertion block 16, upper convex blocks 18 are connected.

[0028] The pull-ring locking fastener 8 includes a long rod body 801. One end of the long rod body 801 is connected with a pull ring 802. The other end of the long rod body 801 is connected with an insertion rod 803. On the side of the insertion rod 803 close to the long rod body 801, limiting bevels 804 are symmetrically connected. At the middle position of the long rod body 801, a claw-shaped part 805 is provided.

[0029] On both sides of the positioning block 6 and at the upper and lower edges of the positioning groove 7, guiding bevels 19 are connected, which is convenient for the claw-shaped part 805 to cooperate with the guiding bevel 19 when the pull ring 902 is pulled, facilitating the long rod body 801 to drive the insertion rod 803 to be pulled outwards, and when inserting, the interaction between the claw-shaped part 805 and the guiding bevel 19 makes the insertion rod 803 convenient to insert.

[0030] Working principle: Assembly and unfolding process:

[0031] First, place the base 1 stably, ensuring that the short side plate slots 10 and the long side plate slots 14 are in an open state. Then, align the short side plate inserts 12 of the two short side plates 2 with the short side plate slots 10 of the base 1 and insert them. Next, align the long side plate inserts 16 of the two long side plates 3 with the long side plate slots 14 of the base 1 and insert them;

[0032] Subsequently, dock the insertion block 5 of the long side plate 3 with the insertion port 4 of the short side plate 2 to realize the connection between the two long side plates 3 and the two short side plates 2. Finally, push the long rod body 801 of the pull-ring lock fastener 8 horizontally along the positioning groove 7 until the insertion rod 803 is inserted into the lock groove 9 on the short side plate 2 to complete the final locking of the box body, which together with the base 1 forms a box body structure with an open upper end for placing, accommodating and transporting items;

[0033] Folding process:

[0034] When folding, first unlock the pull-ring lock fastener 8. Pull the pull ring 802 to disengage the insertion rod 803 from the lock groove 9. Then, push the long side plate 3 inward towards the inside of the box body so that the insertion block 5 is disengaged from the insertion port 4 on the short side plate 2. At this time, the long side plate insert 16 at the lower part of the long side plate 3 can rotate inward towards the inside of the box body within the long side plate slot 14, and the short side plate insert 12 at the lower part of the short side plate 2 can rotate inward towards the inside of the box body within the short side plate slot 10. Thus, fold the two long side plates 3 inward towards the inside of the box body in sequence, and then fold the two short side plates 2 inward towards the inside of the box body in sequence, so that the two long side plates 3 and the two short side plates 2 are folded inside the base 1 for easy storage and transportation.
