[0028] The folding assembly 21 comprises an adjusting keel 211 fixedly installed on one side of the box body 1, the adjusting keel 211 is made of high-strength aluminum alloy material and has the characteristics of light weight and high strength, so that it is not easy to deform during frequent use, a double-head screw 212 is rotatably installed in the middle of the adjusting keel 211, two symmetrically distributed sliding blocks 216 are threadedly installed on the upper part of the double-head screw 212, two support rods 217 that are used in cooperation are rotatably installed in the middle of the two sliding blocks 216, and the middle parts of the two support rods 217 are rotatably connected to each other through a pivot to form an X-shaped cross structure, so that the rotary motion of the double-head screw 212 can be efficiently converted into folding power for the box body 1 during movement, a worm wheel 213 is fixedly installed at the top end of the double-head screw 212, a worm gear 214 is rotatably installed on the upper part of the adjusting keel 211, the worm gear 214 and the worm wheel 213 are rotatably connected to each other, the worm gear 214 and the worm wheel 213 structure can have a self-locking function, so that the box body 1 cannot be restored after being folded, and an inner hexagonal nut 215 is fixedly installed at one end of the worm gear 214;

[0029] The limiting assembly 22 is arranged on the other side of the box body 1 and is used for fixing the two end parts of the side surface of the box body 1.

[0030] The limiting assembly 22 comprises a limiting keel 221 fixedly installed on the other side of the box body 1. The limiting keel 221 is made of aluminum alloy, which has the same material as the adjusting keel 211, so as to ensure the strength and stability of the overall structure. The outer side of the limiting keel 221 is provided with two symmetrically distributed clamping grooves 222. The side end of the box body 1 is slidably clamped in the clamping grooves 222. The shape of the clamping grooves 222 matches the shape of the side end of the box body 1. The inner side of the clamping grooves 222 is provided with anti-skid lines, which increases the friction with the side of the box body 1 and prevents loosening. The middle part of the limiting keel 221 is fixedly installed with two groups of springs 223, which are vertically distributed. One end of each group of springs 223 is fixedly installed with a fixed block 225. The end of the fixed block 225 on one side is an inclined straight surface. The inclined straight surface is provided so that when the end of the box body 1 enters the clamping groove 222, the fixed block 225 can be pressed to move to one side of the spring 223, so that the end of the box body 1 does not directly contact the fixed block 225, and the normal installation operation cannot be completed.

[0031] A limiting rod 226 is fixedly installed on one side of the limiting keel 221. Two symmetrically distributed moving blocks 227 are slidably clamped on the upper part of the limiting rod 226. The other ends of the two supporting rods 217 are movably installed in the middle part of the moving blocks 227. The limiting rod 226 limits and guides the moving blocks 227, so that the moving blocks 227 can stably move up and down under the driving of the supporting rods 217, and the moving range is limited to ensure the safety and reliability of the overall structure.

[0032] A sliding groove 2161 is provided on one side of the adjusting keel 211. Two sliding blocks 216 are slidably clamped in the middle part of the sliding groove 2161. The sliding groove 2161 limits the sliding blocks 216, so that the sliding blocks 216 can slide along the sliding groove 2161 in opposite directions or in the same direction under the rotation of the double-headed screw rod 212.

[0033] Two groups of telescopic rods 224 corresponding to the springs 223 are fixedly installed in the middle part of the limiting keel 221. The springs 223 are sleeved on the outer side of the telescopic rods 224. The other end of the telescopic rod 224 is fixedly installed in the middle part of one end of the fixed block 225. The telescopic rod 224 is made of metal material with high rigidity, which can guide and support the spring 223 during extension and contraction, preventing the spring 223 from being twisted and deformed.

[0034] A plurality of fixed grooves 2251 are provided on the side end of the box body 1. The fixed grooves 2251 are slidably clamped in the inner side of the fixed grooves 2251. The groove end face of the fixed grooves 2251 is edge-processed by aluminum material, so as to prevent the fixed grooves 2251 from being torn under the limitation of the fixed blocks 225.

[0035] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0036] When working, the box body 1 is integrally formed with a hexagonal downward bottom surface, an upper top surface and four side surfaces, the upper top surface is not shown in the figure, and the upper top surface is composed of two flip covers, and the connection is in the same direction as the folding groove 11 to facilitate folding, when folding the large carton, the worker can insert the electric hexagonal wrench into the internal hexagonal nut 215, drive the internal hexagonal nut 215 through the electric hexagonal wrench, rotate the worm 214, drive the meshed worm wheel 213 to rotate, that is, drive the double-headed screw rod 212 to rotate, so that the two sliding blocks 216 move synchronously and oppositely, so that the two supporting rods 217 also move synchronously, thereby increasing the angle between the two supporting rods 217, driving the box body 1 to fold along the folding groove 11, and pulling out the electric hexagonal wrench after folding can avoid the reset of the folded box body 1 under the self-locking structure of the worm wheel 213 and the worm 214;

[0037] When installing the side surface of the box body 1, the two corner ends of the side surface of the box body 1 need to be fixed, at this time, the two end edges of the box body 1 can be inserted into the clamping groove 222, because the outer side of the fixed block 225 is provided with a beveled straight surface, so that when the end edge of the side surface of the box body 1 enters the clamping groove 222, the fixed block 225 is pressed to shrink to the side of the spring 223, so that the spring 223 is synchronously retracted backward, thereby enabling the end edge of the side surface of the box body 1 to be completely inserted into the clamping groove 222, and at this time, the fixed groove 2251 is located in front of the fixed block 225, and the fixed block 225 is popped out under the action of the spring 223, so that it is clamped in the fixed groove 2251, because the other end surface of the fixed groove 2251 is the same as the groove body of the fixed groove 2251, so that when the side surface is pulled outward, it will not fall off.

[0038] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
