[0038] The unfolded box 1 is carried by the hand-carrying slot 3;

[0039] When the box 1 needs to be transported, the side frames 2 on both sides of the bottom frame 6 can be rotated inward to fold the box 1, so that multiple empty boxes 1 can be stacked and transported, thereby avoiding the problem that the area of ​​the cartons is usually large, and only one or two cartons can be transported at a time during manual hand transport, which greatly limits the efficiency of transportation and leads to low transportation efficiency. By folding the cartons, multiple cartons can be transported at a time, thereby improving the transportation efficiency.

[0040] like Figure 8 As shown, a limiting groove 13 and a sliding groove 14 are provided inside the fixed seat 26, and the limiting groove 13 is internally slidably connected to a limiting block 12, and the limiting block 12 is fixedly installed on the outer wall of the first rotating shaft 7, and a first connecting ring 9 is installed at one end of the first rotating shaft 7, and the first connecting ring 9 is embedded in the first movable plate 8, and the first movable plate 8 is slidably installed inside the side frame 2, and a spring 15 is arranged on one side of the first movable plate 8.

[0041] When the box body 1 needs to be unfolded for use, the side frames 2 on both sides of the bottom frame 6 are rotated outward to unfold them. The rotation of the side frames 2 drives the rotation of the first rotating shaft 7. The rotation of the first rotating shaft 7 drives the rotation of the limit block 12, so that the limit block 12 rotates inside the slide groove 14. When the side frames 2 are rotated to be perpendicular to the bottom frame 6, the limit block 12 rotates to one side of the limit groove 13. The elastic potential energy released by the spring 15 pushes the first movable plate 8 to move inward. The movement of the first movable plate 8 drives the movement of the first rotating shaft 7. The movement of the first rotating shaft 7 drives the limit block 12 to move and embed into the limit groove 13. The limit block 12 is limited so that the side frames 2 no longer rotate after being perpendicular to the bottom frame 6, and maintain a vertical state, which is convenient for the box body 1 to be unfolded and used.

[0042] like Figure 6 As shown, a stopper 20 is fixedly connected to the top of the first movable plate 8 , and the stopper 20 is slidably mounted on the top of the side frame 2 .

[0043] A slide groove 14 is provided inside the side frame 2 for the first movable plate 8 to slide, and a stopper 20 is located at the top of the slide groove 14 inside the side frame 2 to prevent external dust from entering the slide groove 14;

[0044] When the box body 1 needs to be folded and transported, the stopper 20 is slid to one side, and the movement of the stopper 20 drives the movement of the first movable plate 8, and the movement of the first movable plate 8 drives the movement of the first connecting ring 9, and the movement of the first connecting ring 9 drives the movement of the first rotating shaft 7, and the movement of the first rotating shaft 7 drives the movement of the limit block 12, so that the limit block 12 slides out of the inside of the limit groove 13 and slides into the inside of the slide groove 14, and then the side frame 2 can be rotated to fold and store the box body 1.

[0045] like Figure 8 As shown, the first connecting ring 9 is rotatably connected to the first movable plate 8 .

[0046] like Figure 5 As shown, gears 18 are provided inside the two side frames 2. The gears 18 are rotatably connected to the side frames 2 via a second rotating shaft 19. Rack plates 17 are meshedly connected on both sides of the gears 18. The rack plates 17 are fixedly mounted on one side of the first movable plate 8.

[0047] When the first movable plate 8 moves, the first movable plate 8 drives the rack plate 17 to move, and the movement of the rack plate 17 drives the gear 18 to rotate, and the rotation of the gear 18 drives the other rack plate 17 to move, so that the two first movable plates 8 in the side frame 2, when any one of the first movable plates 8 is moved, the other one also moves together, so as to facilitate the side frame 2 to release the limit and rotate and fold.

[0048] like Figure 8 As shown, a second connecting ring 10 is fixedly installed at one end of each first rotating shaft 7, a second movable plate 11 is installed on the outer wall of the second connecting ring 10, a connecting plate 16 is fixedly connected to the bottom end of the second movable plate 11, and the connecting plate 16 is slidably installed inside the bottom frame 6.

[0049] When the first rotating shaft 7 moves, the movement of the first rotating shaft 7 drives the movement of the second connecting ring 10, and the movement of the second connecting ring 10 drives the movement of the second movable plate 11. The movement of the second movable plate 11 drives the other second movable plate 11 to move simultaneously through the connecting plate 16, so that the two second movable plates 11 on the same side of the two side frames 2 move simultaneously, and at the same time, through the cooperation of the rack plate 17 and the gear 18, when any one of the stop blocks 20 in the two side frames 2 is moved, the other three stop blocks 20 move simultaneously, and the limit is released at the same time, thereby improving the convenience when folding.

[0050] like Figure 8 As shown, the second connecting ring 10 is rotatably connected to the second moving plate 11 .

[0051] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a first clamping block 21 is fixedly mounted on the top end of the top frame 5 , and a first clamping slot 22 is formed at the bottom end of the bottom frame 6 .

[0052] When stacking two cartons, the first card block 21 at the top of one carton is embedded in the first card slot 22 at the bottom of the other carton to connect the two cartons, thereby improving the stability of the two cartons when connected and facilitating the stacking and transportation of multiple cartons.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, both sides of the top frame 5 are rotatably connected with connecting blocks 23, one side of the two connecting blocks 23 is fixedly installed with a second clamping block 24, and both sides of the bottom frame 6 are provided with a second clamping groove 25.

[0054] The connecting block 23 is rotatably connected to the top frame 5. After the box body 1 is folded, the top frame 5 is located at the top of the bottom frame 6. The second clamping block 24 is embedded in the second clamping groove 25 to clamp the top frame 5 and the bottom frame 6 to prevent the carton itself from gradually unfolding after the external force disappears due to its certain elasticity and restoring force. The box body 1 is kept in a folded state by clamping the top frame 5 and the bottom frame 6, which makes it easy to stack several folded boxes 1 together for transportation, thereby improving transportation efficiency.

[0056] S1: When the box body 1 needs to be folded, one of the stoppers 20 is moved, and the movement of the stopper 20 drives the movement of the first movable plate 8, and the movement of the first movable plate 8 drives the movement of the first connecting ring 9, and the movement of the first connecting ring 9 drives the movement of the first rotating shaft 7, and the movement of the first rotating shaft 7 drives the movement of the limit block 12, so that the limit block 12 slides out of the limit groove 13 and slides into the slide groove 14;

[0057] S2: At the same time, the movement of the first movable plate 8 drives the movement of the rack plate 17, the movement of the rack plate 17 drives the gear 18 to rotate, and the rotation of the gear 18 drives the other rack plate 17 to move, so that the two first movable plates 8 in the side frame 2 move relatively at the same time;

[0058] S3: At the same time, the movement of the first rotating shaft 7 drives the movement of the second connecting ring 10, and the movement of the second connecting ring 10 drives the movement of the second movable plate 11. The movement of the second movable plate 11 drives another second movable plate 11 to move simultaneously through the connecting plate 16, so that the four first rotating shafts 7 move simultaneously and the limit is released;

[0059] S4: Then the two side frames 2 are rotated inwards to fold the box body 1;
