[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figures 1-4 , an embodiment provided by the present invention: The inner bottom of the main body enclosure panel 1 is fixedly arranged outside the folding mechanism 14. A handle 202 is fixedly arranged at the front end of the box cover 201. Hollow columns 13 are fixedly arranged outside multiple second fixed plates 12. A plug pin 11 is rotatably connected inside the hollow column 13. The top end of the plug pin 11 is fixedly connected to a first fixed plate 10. One end of the first fixed plate 10 is fixedly connected to a movable enclosure panel 4. A notch 5 is opened at the bottom of the movable enclosure panel 4. Multiple first support columns 6 are evenly and fixedly arranged at the bottom of the bottom cover 301. Multiple second support columns 7 are fixedly arranged at the bottom ends of the first support columns 6. A second connecting block 1403 is hinged to a first connecting block 1401. Connecting locks 302 are fixedly arranged on the front and rear sides of the bottom cover 301. A rotating rod 8 is rotatably installed in the middle of the second support column 7. Rollers 9 are fixedly arranged on both sides of the rotating rod 8.

[0026] Specifically, the main body panel 1 moves along with the folding mechanism 14. The handle 202 is used for conveniently lifting the box after folding. The second fixing plate 12 fixes the hollow column 13. The hollow column 13 is rotatably connected to the bolt 11 to facilitate the rotation of the movable panel 4. The bolt 11 is fixed on the first fixing plate 10, and the other side of the first fixing plate 10 is fixed on the movable panel 4. The notch 5 at the lower end of the movable panel 4 is to prevent the folding mechanism 14 from affecting the movable panel 4 when the movable panel 4 is folded. The first support column 6 is used to support the panel box, and the second support column 7 is used to connect the rotating rod 8 and the first support column 6. The first connecting block 1401 is hinged to the second connecting block 1403 to limit the rotatable range of the folding mechanism 14. The connecting lock 302 is used to connect with the buckle 204. The roller 9 moves along with the movement of the rotating rod 8.

[0027] Refer to Figure 1 、 Figure 2 As shown in, a top cover mechanism 2 is movably arranged at the top of the main body panel 1. The top cover mechanism 2 includes a box cover 201. Two first fixing bases 203 are fixedly arranged on the front and rear sides of the box cover 201. The bottom ends of the two first fixing bases 203 are fixedly connected with a buckle 204. Two third fixing plates 205 are fixedly arranged on both sides of the box cover 201. An indicating lock 206 is rotatably arranged on one side of the two third fixing plates 205.

[0028] Specifically, the top cover mechanism 2 is not fixed to the main body panel 1 to facilitate the folding and use of the panel box. The box cover 201 is used to cover the panel box. The first fixing base 203 is used to fix the buckle 204. The third fixing plate 205 is used to connect the indicating lock 206.

[0029] Refer to Figure 1 、 Figure 3 As shown in, a plurality of second fixing plates 12 are evenly and fixedly arranged on both sides inside the main body panel 1. A bottom plate mechanism 3 is arranged at the bottom of the main body panel 1. The bottom plate mechanism 3 includes a bottom cover 301. Two second fixing bases 303 are fixedly arranged on both sides of the bottom cover 301. A buckle ring 304 is fixedly arranged on the top of the two second fixing bases 303.

[0030] Specifically, the second fixing plate 12 is used to fix the main body panel 1 and the hollow column 13. The second fixing bases 303 on both sides of the bottom cover 301 are used to fixedly connect the bottom cover 301 and the buckle ring 304. When folding, the buckle ring 304 is inserted into the indicating lock 206 to fix it.

[0031] Refer to Figure 1 、 Figure 2 、 Figure 4, a plurality of folding mechanisms 14 are evenly and fixedly arranged on the top of the bottom plate mechanism 3. The plurality of folding mechanisms 14 each include a first connecting block 1401. Guide rails 1402 are provided on both sides of the first connecting block 1401. Limiting blocks 1405 are slidably connected to the outer sides of the two guide rails 1402. A connecting rod 1404 is fixedly connected to the adjacent sides of the two limiting blocks 1405.

[0032] Specifically, the plurality of folding mechanisms 14 enhance stability. The bottom end of the first connecting block 1401 is fixed on the bottom cover 301. The guide rails 1402 provided on both sides of the first connecting block 1401 facilitate the movement of the connecting rod 1404 when the folding mechanism 14 rotates. The limiting blocks 1405 prevent deviation and displacement when the connecting rod 1404 moves.

[0033] Working principle: Through the guide rails 1402 provided on both sides of the first connecting block 1401 of the folding mechanism 14, when the mechanism is in use, the second connecting block 1403 opens, driving the main body enclosure 1 to open. The second connecting block 1403 drives the connecting rod 1404 to move within the guide rails 1402. After the second connecting block 1403 is fully opened, the connecting rod 1404 moves to the end of the guide rail 1402 and cannot move further, forming a self-locking state. The main body enclosure 1 stops moving and is fixed on the bottom cover 301, effectively improving the firmness of the foldable plastic enclosure box during use;

[0034] Secondly, after folding the enclosure box, the buckle 204 on the box cover 201 is snap-connected to the connection lock 302 on the bottom cover 301, and the indicating lock 206 is inserted into the buckle 304 to fix the top cover mechanism 2 and the bottom plate mechanism 3. It can be carried by the handle 202. During the use of the enclosure box, when there are items in the box that need to be moved, it can be moved through the rollers 9 at the bottom of the bottom plate mechanism 3, improving the convenience of the enclosure box.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
