Of course, it should be noted that the side plates and the base 1 may be hinged by other means without departing from the scope of the present invention, such as hinges, which are disposed in the hinge grooves 14.

In addition, as shown in fig. 8 and 9, any pair of side plates is located between the other pair of side plates, that is, the pair of long side plates 4 is located between the pair of short side plates 5, and the pair of short side plates 5 can be prevented from being turned inside the container by the first long side plate 4 abutting against the pair of short side plates 5.

In order to lock the adjacent two side plates, as shown in fig. 11, 12, and 27, the lock mechanism 2 includes: a stop 21 and a movable block 22, the stop 21 being located on a side edge 41 of one side plate of any one of the pair of side plates, that is, on a side edge 41 of a pair of long side plates 4, the side edge 41 being disposed opposite an adjacent side plate of the one side plate, that is, the side edge 41 being disposed opposite an adjacent short side plate 5. The movable block 22 is slidably disposed on the adjacent side plate along the vertical direction, and the movable block 22 moves upward or downward to a predetermined position to abut against the stopper 21. Specifically, in the present embodiment, the movable block 22 is located on the short side plate 5, and is capable of sliding in the height direction of the short side plate 5. When the movable block 22 moves downwards to a preset position and abuts against the inner side of the movable block 22 facing the box body, the long side plate 4 can be prevented from turning over in the box body. When the movable block 22 moves upwards, the movable block 22 is separated from the stop block 21, the movable block 22 does not abut against the stop block 21, and the long side plate 4 can turn towards the inside of the box body.

In order to drive the movable blocks 22 to move up and down, as shown in fig. 27, the short side plates 5 are further provided with connecting plates 23, the connecting plates 23 are fixedly connected with the two movable blocks 22 arranged at the two ends of the short side plates 5, and the two movable blocks 22 can be driven to move up and down by pulling the connecting plates 23 to move up and down. In order to prevent the connection plate 23 from being displaced, the short side plates 5 have a step surface 25 thereon, and the step surface 25 is located below the connection plate 23 and supports the connection plate 23. Meanwhile, the positioning plate 26 is arranged on the inner side of the short side plate 5, the positioning plate 26 is positioned on the side of the connecting plate 23 facing the box body, and the position of the connecting plate 23 can be basically limited by the short side plate 5, the positioning plate 26 and the step surface 25, so that the connecting plate 23 can only move up and down. As shown in fig. 27, the connection plate 23 is further provided with fixing grooves 231, and the fixing grooves 231 are provided along the height direction of the short side plates 5 and penetrate the connection plate 23. Still set up elastic hook 24 on the short lateral plate 5, this elastic hook 24 passes this connecting plate 23 and catches on and hugs closely connecting plate 23, prevents that connecting plate 23 from moving down because of self gravity. In the present embodiment, the elastic hook 24 and the fixing groove 231 are two.

Of course, the lock mechanism 2 may have other configurations than the above-described one without departing from the scope of the present invention. For example, a through hole penetrating through the short side plate 5 can be formed in the short side plate 5, a blind hole is formed in the side plate of the long side plate 4, when the long side plate 4 and the short side plate 5 are vertically arranged, the through hole and the blind hole are coaxially arranged, meanwhile, the locking mechanism 2 is a bolt, the bolt is inserted into the through hole and the blind hole, and when the bolt is required to be unlocked, the bolt can be withdrawn from the blind hole.

In addition, as shown in fig. 11 to 13, 17, 18 and 27, any two adjacent side plates are also snapped together, for example, a first hook 46 is provided on the long side plate 4, a second hook 52 is provided on the short side plate 5, and the first hook 46 is hooked on the second hook 52, so that the long side plate 4 and the short side plate 5 are snapped together.

As shown in fig. 9 and 11, a first portion 16 of the base 1 hinged to the pair of side plates is lower than a second portion 17 of the base 1 hinged to the pair of side plates by a predetermined distance, and the pair of driving members 3 correspond to the pair of side plates. In the present embodiment, any one pair of side plates is a pair of long side plates 4, and the other pair of side plates is a pair of short side plates 5. That is, the pair of driving members 3 correspond to the pair of long side plates 4, and can drive the pair of long side plates 4 to turn over into the container, and a first portion 16 of the base 1 hinged to the pair of long side plates 4 is lower than a second portion 17 of the base 1 hinged to the pair of short side plates 5 by a predetermined distance, which is the thickness of the long side plates 4.

Because the articulated position of base 1 and a pair of long curb plate 4 will hang down than base 1 and a pair of short curb plate 5 articulated position and predetermine the distance, consequently when long curb plate 4 flatly put the back, long curb plate 4 can not interfere with short curb plate 5, avoids short curb plate 5 can not flatly the phenomenon to take place.

While the preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide yet further embodiments.

8. The collapsible container of claim 2 wherein the drive member is disposed on the base and abuts against the end of the respective side panel that is distal from the interior of the container.

9. The foldable container according to claim 8, wherein the elastic member is a second torsion spring, an axis of the second torsion spring is parallel to the corresponding side plate, and a second torsion arm of the second torsion spring abuts against an end of the lower end surface away from the inside of the container.

10. The collapsible container of claim 9 wherein the end of the lower end surface remote from the interior of the container has a projection which abuts the second torque arm.

11. The collapsible container of claim 8, wherein the actuating member further comprises an actuating block, the actuating block having an upper surface that is a sloped surface that slopes from top to bottom into the container, and a lower surface that abuts the sloped surface, and wherein the resilient member is disposed below the actuating block and is operable to drive the actuating block in an up-and-down motion.

12. The foldable container according to claim 11, wherein a first guide rod is further disposed below the driving block, the first guide rod is disposed vertically, and the elastic member is sleeved on the first guide rod;

and/or a second guide rod is also arranged on the base, the second guide rod is vertically arranged relative to the driving block, and the elastic piece is sleeved on the second guide rod;

and/or the driving piece further comprises a sleeve arranged below the driving block, the sleeve is vertically arranged, and the elastic piece is located in the sleeve.

13. The collapsible container of claim 8 wherein the upper surface of the base defines a receiving cavity and the actuating member is disposed within the receiving cavity.

14. The collapsible container of claim 1 wherein the base is further formed with a plurality of hinge slots, each hinge slot being located below a respective side panel, the hinge slots opening onto the upper surface of the base and into the container;

the bottom of the side plate is provided with a plurality of hinged pieces, each hinged piece is arranged along the length direction of the side plate, and the hinged pieces are rotatably arranged in the corresponding hinged grooves in a one-to-one correspondence manner around the length direction of the side plate.

15. A collapsible container as claimed in claim 14 wherein any pair of side panels is located between another pair of said side panels, said locking mechanism comprising:
