Description

Technical Field

[0001] This invention belongs to the field of logistics transportation equipment technology, and specifically relates to a folding box for logistics transportation. Background Technology

[0002] With soaring global logistics and transportation costs and increasing warehousing space requirements for "last-mile" delivery, traditional standard containers have revealed significant shortcomings in empty container stacking and transportation. Empty container stacking occupies a large area and incurs high return transportation costs, severely squeezing the profit margins of logistics companies. Statistics show that the return transport of an empty standard 40-foot container typically requires the same space as a fully loaded container, leading to an increase in logistics costs of approximately 30%-50%.

[0003] To overcome the aforementioned shortcomings, some foldable containers have emerged in the existing technology. However, existing foldable containers still have many deficiencies: First, folding and unfolding operations mostly rely on manual labor, which is extremely laborious and inefficient when the container is large or the cargo is heavy. Second, the folding structure results in many gaps between the panels, leading to poor dustproof and waterproof performance, making it difficult to meet the transportation requirements of precision instruments or high-value-added goods. Third, the folding mechanism is mostly exposed, making it susceptible to damage from dust, rain, and snow, and the structural stability of the folded container is insufficient, unable to withstand the vibration and impact during stacking or long-distance transportation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a folding box for logistics transportation.

[0005] The technical solution adopted to solve the above technical problems is: a folding box for logistics transportation, including a bottom plate and a reduction motor. Two connecting bases are symmetrically fixed to the top of the bottom plate. The top of each connecting base is rotatably connected to a side plate. Two side plates are rotatably connected between the opposite surfaces of the two connecting bases. A top plate is slidably connected to the top of the side plate. A folding drive assembly is provided below the top plate. A locking mechanism for locking and limiting the reduction motor is provided at the top of the top plate. The reduction motor, in cooperation with the folding drive assembly, drives the two side plates to extend and fold synchronously. A sealing limiting mechanism for mutual limiting is provided between the bottom plate, side plate one, side plate two, and top plate. A quick-release mechanism is provided between the side plate two and the sealing limiting mechanism. The folding drive assembly includes a displacement mechanism and a transmission mechanism. The displacement mechanism is rotatably connected to the top outer wall of the two side plates, and the transmission mechanism is drively connected to the displacement mechanism.

[0006] Furthermore, the sealing and limiting mechanism includes a base plate, with sealing baffle one and sealing baffle two symmetrically fixed to the four outer walls of the base plate. The top of sealing baffle one is higher than the top of the connecting base, and the height of sealing baffle two is higher than the rotating connection of side plate two. The height of the rotating connection of side plate two on one side is higher than the height of the rotating connection of side plate two on the other side, and the distance between the two rotating connections is not less than the thickness of side plate two. It also includes a sealing enclosure plate fixed to the outer wall of the top plate, and sealing side plates fixed to both sides of side plate one.

[0007] Through the above technical solution, the fit and contact between the various sealing components form a continuous multi-seal path. The arc-shaped bottom design ensures that the sealing side plate remains in contact with the sealing baffle plate during rotation, avoiding rotational interference and sealing failure, and significantly improving the overall sealing level of the enclosure.

[0008] Furthermore, the inner wall of the first sealing baffle is in contact with the outer wall of the adjacent side plate, the inner wall of the second sealing baffle is in contact with the outer wall of the adjacent side plate, the bottom end of the sealing side plate is in contact with the top end of the second sealing baffle on the same side, and the bottom end of the sealing side plate is arc-shaped. The inner walls of the first sealing baffle, the second sealing baffle, the sealing side plate, and the sealing enclosure are all covered with and fixed sealing gaskets.

[0009] Through the above technical solution, a dynamic sealing fit is formed between the sealing plates. When the first side plate rotates, its outer wall is always in contact with the inner wall of the first sealing baffle; when the second side plate rotates, its outer wall is always in contact with the inner wall of the second sealing baffle. The arc design at the bottom of the sealing side plate allows it to slide smoothly without jamming when it contacts the top of the second sealing baffle. At the same time, in conjunction with the sealing gasket, a full-range, no-dead-angle waterproof and dustproof seal is achieved when the box is unfolded, effectively protecting the internal goods.

[0010] Furthermore, the displacement mechanism includes strip-shaped limiting shells symmetrically fixed to the bottom of the top plate, and the strip-shaped limiting shells are all arranged along the length direction of the box. A strip-shaped protective shell is fixedly connected through the two strip-shaped limiting shells. A bidirectional threaded rod is rotatably connected between the inner walls of the two ends of the strip-shaped limiting shell. A slider is symmetrically arranged through the threaded connection on one side wall of each bidirectional threaded rod. A hinge is fixedly connected to the bottom end of each slider. The movable page of the hinge is fixed to the top outer wall of the adjacent side plate. The slider slides with the strip-shaped limiting shell. A bellows protective cover is installed between the outer walls of both sides of the slider and the inner wall end face of the strip-shaped limiting shell. The transmission mechanism synchronously drives the bidirectional threaded rods on both sides to rotate synchronously.

[0011] With the above technical solution, when the bidirectional threaded rod rotates, the two symmetrical sliders on it will move closer or further away in opposite directions, thereby driving the top of the side plate to fold inward or unfold outward through the hinge, realizing the folding and extension of the side plate; the bellows cover effectively seals the sliding space of the slider, ensuring transmission accuracy and service life.

[0012] Furthermore, the transmission mechanism includes a bevel gear 1 sleeved and fixed to the outer wall of two bidirectional threaded rods 1, and a transmission rod rotatably installed inside the strip-shaped protective shell. Both ends of the transmission rod are fixedly connected to bevel gears 2, and each bevel gear 2 meshes with the adjacent bevel gear 1. The meshing directions of the bevel gears 1 on both sides are opposite. A bevel gear 3 is sleeved and fixed to the outer wall of the middle section of the transmission rod. A bevel gear 4 is meshed and connected to the outer wall of the bevel gear 3. A drive rod is fixedly connected to the top of the bevel gear 4. The top of the drive rod is rotatably connected to the top of the top plate. A limiting groove is formed at the center of the top of the drive rod. The limiting groove is adapted to the shape of the output shaft of the reduction motor.

[0013] With the above technical solution, after the output shaft of the geared motor is inserted into the limiting groove, it drives the drive rod to rotate. The drive rod drives the transmission rod to rotate through bevel gear four and bevel gear three. The bevel gear two at both ends of the transmission rod simultaneously drives the bevel gear one on both sides to rotate. Since the meshing direction of the bevel gear one on both sides is opposite, the rotation direction of the two bidirectional threaded rods one is the same, thereby ensuring that the side plates one on both sides fold or unfold synchronously, effectively avoiding the torsion and deformation of the box.

[0014] Furthermore, the locking mechanism includes a limiting frame fixed to the top of the top plate. The outer side wall of the limiting frame is symmetrically fixed to a limiting shell. The inner sides of the limiting shells are slidably connected to symmetrically arranged limiting sealing plates. A bidirectional threaded rod is rotatably connected between the two ends of one side of the limiting frame. The side wall of the bidirectional threaded rod is threadedly connected to the side wall of the limiting sealing plate. One end of the bidirectional threaded rod is fixed to a handle. The limiting frame is provided with a plurality of positioning posts fixed to the top of the top plate. The positioning posts correspond to the positions of the geared motor mounting holes.

[0015] With the above technical solution, when the geared motor is placed in the limiting frame and the positioning pin is inserted into the mounting hole of the geared motor for positioning, the rotating handle makes the two-way threaded rod rotate, driving the two limiting sealing plates on both sides to slide towards each other, clamping and fixing the mounting plate of the geared motor in the limiting frame, providing a stable mounting base for the geared motor, and also allowing the geared motor to be quickly disassembled after use, so that the geared motor can be used as a power source for the extension or folding of the next container. It can be used repeatedly, improving folding efficiency while reducing usage costs.

[0016] Furthermore, the quick-release mechanism includes a fixing hook fixed to the outer side wall of the top of the second side panel, a fastener fixed to the outer side wall of the sealing panel, and a through hole opened in the side wall of the sealing panel. The fixing hooks are all positioned corresponding to the through holes, and the fixing hooks pass through the through holes and engage with the fasteners. Several fixing hooks, fasteners, and through holes are provided.

[0017] With the above technical solution, when the box is unfolded, the fixing hook at the top of the second side panel passes through the through hole on the sealing plate and engages with the buckle on the outside, which can quickly fix the second side panel to the top plate without the need for additional tools; when folding is required, simply pull the buckle to release the fixing hook, and the second side panel can be rotated around its bottom connection and folded inward. The whole process is quick and convenient, which greatly improves the efficiency of packing and unloading.

[0018] Furthermore, the top and side walls of the slider are provided with mounting grooves along the length of the strip-shaped limiting shell, and pulleys are installed in the mounting grooves. The rolling surfaces of the pulleys are in rolling contact with the inner wall of the strip-shaped limiting shell.

[0019] Through the above technical solution, the slider forms a rolling engagement with the inner wall of the strip-shaped limiting shell through pulleys in multiple directions, which significantly reduces the resistance when the slider moves, making the folding and unfolding of the side plate smoother, while reducing the driving load and wear of the threaded rod.

[0020] The beneficial effects of this invention are as follows: (1) By setting up the folding drive assembly, the geared motor and the transmission mechanism drive the two bidirectional threaded rods on both sides to rotate synchronously, thereby driving the side plate one and the side plate two to automatically unfold or fold, realizing the electric rapid deformation of the box, and locking it immediately after deformation to ensure the stability of the box structure. At the same time, the box can be folded vertically, significantly reducing the return transportation cost of empty boxes, improving logistics turnover efficiency, reducing manual labor intensity, and reducing the storage area. (2) By setting a sealing limit mechanism, the multi-layer sealing structure consisting of sealing baffle one, sealing baffle two, sealing side plate and sealing enclosure plate, combined with the filling effect of sealing gasket, forms a closed waterproof and dustproof space when the box is unfolded, which greatly improves the waterproof and dustproof performance of the box. At the same time, the height difference design at the rotating connection ensures that the side plate two does not interfere when folded and fits tightly when unfolded, effectively improving the protection level of the box. (3) Through the quick-release mechanism and the closed locking mechanism, the side plate and the top plate can be quickly locked and released. At the same time, the geared motor can be quickly and firmly locked on the top plate when in use. After use, it can be disassembled and transferred to other containers. The overall structure is compact and easy to operate, which not only ensures the safety during transportation, but also facilitates daily maintenance and storage, and reduces the cost of use.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figures 1-12 As shown, a folding box for logistics transportation in this embodiment includes a base plate 1 and a reduction motor 7. Two connecting bases 9 are symmetrically fixed to the top of the base plate 1. The top of each connecting base 9 is rotatably connected to a side plate 2. Two side plates 3 are rotatably connected between the opposite surfaces of the two connecting bases 9. A top plate 4 is slidably connected to the top of the side plates 2. A folding drive assembly 5 is provided below the top plate 4. A locking mechanism 6 is provided on the top of the top plate 4 to lock and limit the reduction motor 7. The reduction motor 7, in conjunction with the folding drive assembly 5, drives the two side plates 2 to extend and fold synchronously. The base plate 1, side plates 2, side plates 3, and top plate 4 are all made of 1.1mm thick B800NQ or equivalent material, and their main structural components are made of high-strength steel (YP≥550MPa). A sealing limiting mechanism is provided between the base plate 1, side plates 2, side plates 3, and top plate 4 to limit each other. A quick-release mechanism 8 is provided between the side plates 3 and the sealing limiting mechanism. The folding drive assembly 5 includes a displacement mechanism and a transmission mechanism. The displacement mechanism is rotatably connected to the top outer wall of the two side plates 2, and the transmission mechanism is connected to the displacement mechanism in a transmission manner.

[0025] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the sealing and limiting mechanism includes sealing baffle 101 and sealing baffle 202 symmetrically fixed to the four outer walls of the base plate 1. The top of sealing baffle 101 is higher than the top of the connecting base 9, and the height of sealing baffle 202 is higher than the rotating connection of side plate 23. The height of the rotating connection of one side plate 23 is higher than the height of the rotating connection of the other side plate 23, and the distance between the two rotating connections is not less than the thickness of side plate 23. It also includes a sealing enclosure plate 401 fixed to the outer wall of the top plate 4, and sealing side plates 201 fixed to both sides of side plate 12. The sealing baffle 101, sealing baffle 2 102, sealing enclosure 401, and sealing side plate 201 together constitute a multi-layer labyrinth-style sealing structure. The sealing baffle 101 is higher than the connecting base 9, which can effectively cover the rotation gap between the side plate 2 and the base plate 1. The sealing baffle 2 102 is higher than the rotation connection point, which can cover the rotation gap between the side plate 2 3 and the base plate 1. The rotation connection point of the two side plates 2 3 adopts a height difference design, which ensures that the two side plates 2 3 can completely overlap and not interfere with each other when folded, while ensuring a tight fit at the connection point in the unfolded state, thus improving the overall sealing performance.

[0026] The inner walls of sealing baffle 101 are all in contact with the outer walls of the adjacent side plate 2, and the inner walls of sealing baffle 202 are all in contact with the outer walls of the adjacent side plate 3. The bottom ends of sealing side plates 201 are in contact with the top ends of sealing baffle 202 on the same side, and the bottom ends of sealing side plates 201 are arc-shaped. Sealing gaskets are laid and fixed on the inner walls of sealing baffle 101, sealing baffle 202, sealing side plates 201, and sealing enclosure 401. The sealing gaskets are preferably three-lip EPDM (ethylene propylene diene monomer) sealing strips, which can ensure sealing from -40°C to +70°C. It maintains good elasticity even under extreme temperature differences of °C, meeting the IP54 protection level; a dynamic sealing fit is formed between the sealing plates, and when the side plate 12 rotates, its outer wall is always in contact with the inner wall of the sealing baffle 101; when the side plate 23 rotates, its outer wall is always in contact with the inner wall of the sealing baffle 2102; the arc design at the bottom of the sealing side plate 201 allows it to slide smoothly without jamming when it contacts the top of the sealing baffle 2102, and together with the sealing gasket, it achieves all-round, no dead angle waterproof and dustproof sealing when the box is unfolded, effectively protecting the internal goods.

[0027] like Figure 6 , Figure 7 , Figure 11 As shown, the displacement mechanism includes strip-shaped limiting shells 501 symmetrically fixed to the bottom of the top plate 4, and the strip-shaped limiting shells 501 are all arranged along the length of the box. A strip-shaped protective shell 505 is fixedly connected through the two strip-shaped limiting shells 501. A bidirectional threaded rod 502 is rotatably connected between the inner walls of the two ends of the strip-shaped limiting shell 501. A slider 503 is symmetrically arranged and threaded through the side wall of each bidirectional threaded rod 502. A hinge 504 is fixedly connected to the bottom of each slider 503. The movable page of the hinge 504 is fixed to the top outer wall of the adjacent side plate 2. The slider 503 slides with the strip-shaped limiting shell 501. A bellows protective cover 513 is installed between the outer walls of both sides of the slider 503 and the inner wall end face of the strip-shaped limiting shell 501. The transmission mechanism synchronously drives the bidirectional threaded rods 502 on both sides to rotate synchronously. The strip-shaped limiting shell 501 not only serves as a guide rail for the slider 503, but also provides protection and support for the bidirectional threaded rod 502. The slider 503 is connected to the side plate 2 via the hinge 504, allowing the side plate 2 to rotate around the axis of the hinge 504 while moving horizontally with the slider 503, thus achieving a sliding connection between the top plate 4 and the side plate 2. The bellows cover 513 ensures that the threaded portion of the bidirectional threaded rod 502 is always covered, effectively preventing wear on the threads from dust and debris during transportation, and guaranteeing the accuracy and lifespan of long-term use.

[0028] The transmission mechanism includes a bevel gear 507 sleeved and fixed to the outer wall of two bidirectional threaded rods 502 and a transmission rod 506 rotatably installed inside the strip-shaped protective shell 505. Both ends of the transmission rod 506 are fixedly connected to bevel gears 508, which mesh with the adjacent bevel gears 507. The meshing directions of the two bevel gears 507 are opposite. A bevel gear 509 is sleeved and fixed to the outer wall of the middle section of the transmission rod 506. A bevel gear 511 is meshed with the outer wall of the bevel gear 509. A drive rod 510 is fixedly connected to the top of the bevel gear 511. The top of the drive rod 510 is rotatably connected to the top of the top plate 4. A limiting groove 512 is opened at the center of the top of the drive rod 510. The limiting groove 512 is adapted to the shape of the output shaft of the reduction motor 7. Simply insert the output shaft of a geared motor 7 into the limiting slot 512 and drive the drive rod 510 to rotate. This will drive the transmission rod 506 and the bevel gears 508 at both ends to rotate through the meshing transmission of the bevel gear 4 511 and the bevel gear 3 509. In turn, the meshing will drive the bevel gear 1 507 on both sides and the bidirectional threaded rod 1 502 to rotate synchronously. The meshing direction of the bevel gear 1 507 on both sides is opposite, so that the sliders 503 on the two bidirectional threaded rods 1 502 can move synchronously towards or away from each other. This will drive the side plates 1 2 on both sides to extend or fold synchronously, realizing the synchronous action of both sides driven by a single power source. This achieves efficient and automated operation (folding time of a single box ≤ 8 minutes). Moreover, the locking characteristics of the extended or folded box, combined with the threaded structure, ensure that each state can be stably locked, improving the stability of the box structure.

[0029] like Figure 1 , Figure 8 As shown, the locking mechanism 6 includes a limiting frame 601 fixed to the top of the top plate 4. The outer side wall of the limiting frame 601 is symmetrically fixed to a limiting shell 602. The inner sides of the limiting shells 602 are slidably connected to symmetrically arranged limiting sealing plates 605. A two-way threaded rod 603 is rotatably connected between the two ends of one side of the limiting frame 601. The side wall of the two-way threaded rod 603 is threadedly connected to the side wall of the limiting sealing plate 605. One end of the two-way threaded rod 603 is fixed to a handle 604. The limiting frame 601 is provided with a number of positioning posts 606 fixed to the top of the top plate 4. The positioning posts 606 correspond to the positions of the mounting holes of the reduction motor 7. When the geared motor 7 is placed in the limiting frame 601 and the positioning pin 606 is inserted into the mounting hole of the geared motor 7 for positioning, the handle 604 is rotated to rotate the double threaded rod 603, driving the two limiting sealing plates 605 on both sides to slide towards each other, clamping and fixing the mounting plate of the geared motor 7 in the limiting frame 601, providing a stable mounting base for the geared motor 7, and also allowing the geared motor 7 to be quickly disassembled after use, so that the geared motor 7 can be used as a power source for the extension or folding of the next container. It can be used repeatedly, improving folding efficiency while reducing usage costs; at the same time, the closed structure also plays a role in dust and rain protection. In the non-operating state, the limiting groove 512 of the limiting sealing plate 605 protects the inner cavity of the limiting frame 601 to prevent the accumulation of impurities.

[0030] like Figure 1 , Figure 2 , Figure 10 As shown, the quick-release mechanism 8 includes a fixing hook 801 fixed to the outer side wall of the top of the second side panel 3, a latch 802 fixed to the outer side wall of the sealing enclosure 401, and a through hole 803 opened in the side wall of the sealing enclosure 401. The fixing hook 801 is positioned corresponding to the through hole 803. The fixing hook 801 passes through the through hole 803 and engages with the latch 802. There are several fixing hooks 801, latches 802, and through holes 803. When the box is unfolded, the fixing hook 801 at the top of the second side panel 3 passes through the through hole 803 on the sealing enclosure 401 and engages with the latch 802 on the outside, which can quickly fix the second side panel 3 to the top panel 4, forming a rigid overall frame to withstand the stacking load without the need for additional tools. When folding is required, simply pull the latch 802 to release the fixing hook 801, and the second side panel 3 can be folded inward around its bottom rotating connection. The whole process is quick and convenient, which greatly improves the efficiency of packing and unloading.

[0031] like Figure 12 As shown, the top and side walls of the slider 503 are provided with mounting grooves 5031 along the length of the strip-shaped limiting shell 501. Each mounting groove 5031 is equipped with a pulley 5032. The rolling surfaces of the pulleys 5032 are in rolling contact with the inner wall of the strip-shaped limiting shell 501. The slider 503 and the strip-shaped limiting shell 501 achieve rolling friction through the pulleys 5032, which significantly reduces the resistance when the slider 503 moves, making the drive of the bidirectional threaded rod 502 easier and smoother. It also reduces the wear of the slider 503 and the strip-shaped limiting shell 501, and extends the service life of the structure.

[0032] The working principle of this embodiment is as follows: When unfolding the folded box, the independent geared motor 7 is placed in the limiting frame 601 at the top of the top plate 4, so that the positioning post 606 is inserted into the motor mounting hole to complete the initial positioning. Then, the handle 604 is rotated to drive the bidirectional threaded rod 603 to rotate, causing the two limiting sealing plates 605 on both sides to slide towards each other, clamping and fixing the mounting plate of the geared motor 7. At this time, the output shaft of the geared motor 7 is just inserted into the limiting groove 512 at the top of the drive rod 510, completing the power coupling.

[0033] When the geared motor 7 is started, its output shaft drives the drive rod 510 to rotate through the limiting groove 512. This rotation is achieved by the bevel gear 4 511 meshing with the transmission bevel gear 3 509, causing the transmission rod 506 to rotate. The bevel gears 2 508 at both ends of the transmission rod 506 mesh with the bevel gears 1 507 on both sides, thereby driving the two bidirectional threaded rods 1 502 to rotate synchronously. Since the meshing directions of the bevel gears 1 507 on both sides are opposite, the two sliders 503 on each bidirectional threaded rod 1 502 will slide synchronously in opposite directions along the length of the strip-shaped limiting shell 501 (i.e., move outwards to both sides of the housing). The pulleys 5032 of the sliders 503 roll in contact with the inner wall of the strip-shaped limiting shell 501, greatly reducing frictional resistance. At the same time, the bellows protective covers 513 on both sides of the sliders 503 extend and retract with the sliders 503, always covering the threaded part of the bidirectional threaded rods 1 502, effectively preventing dust and debris from wearing the threads.

[0034] Slider 503 drives the top of side panel 2 to move horizontally outward via hinge 504. Under the constraint of the bottom of the connecting base 9, side panel 2 gradually flips upward around the bottom rotation axis from a horizontally stacked state until it reaches a vertically unfolded state. When slider 503 moves to the extreme position at the end of the strip-shaped limiting shell 501, side panel 2 is fully vertically unfolded. In the next step, the two side panels 3 on both sides are vertically flipped in sequence to complete the unfolding of the box.

[0035] During the unfolding of the side panels, the top plate 4 rises as the top of side panel 2 slides. When the side panels are fully unfolded, the top plate 4 accurately covers the top of the box composed of the bottom plate 1, side panel 2, and side panel 3, forming a closed space. At this time, the fixing hook 801 on the top of side panel 3 passes through the through hole 803 on the sealing plate 401. The operator manually pulls the latch 802 to engage with the fixing hook 801, quickly locking side panel 3 and top plate 4 together, making the entire box a rigid integral frame. At the same time, the self-locking characteristic of the threaded structure ensures stable locking in the unfolded state.

[0036] As the enclosure unfolds, the outer wall of side panel 2 remains in contact with the inner wall of sealing baffle 101 on the bottom plate 1, covering any rotational gaps; the outer wall of side panel 3 remains in contact with the inner wall of sealing baffle 102; the bottom ends of the sealing side panels 201 on both sides of side panel 2 slide in close contact with the top ends of the sealing baffle 102 on the same side; the sealing surround 401 around the top plate 4 forms an enclosing overlap with each side panel and sealing side panel 201. The three-lip EPDM sealing strips pre-installed on the inner side of each sealing plate undergo elastic deformation under contact pressure, collectively forming a multi-layered labyrinthine sealing path, effectively preventing moisture and dust intrusion and meeting the IP54 protection rating.

[0037] When folding the box, first pull the buckle 802 to disengage the fixing hook 801 from the buckle 802, releasing the locking of the side plate 2 3 and the top plate 4. The side plate 2 3 is no longer constrained by the top plate 4 and flips into the box one by one. Since the rotation connection of the two side plates 2 3 adopts the height difference design, the two side plates 2 3 can completely overlap and not interfere with each other during the folding process, and finally lie flat on the bottom plate 1. Next, the reduction motor 7 is coupled with the limiting groove 512 again. First, the reduction motor 7 is started to rotate in the opposite direction. The power is transmitted in the opposite direction to the two bidirectional threaded rods 502 through the transmission mechanism, driving the two sliders 503 on each rod to slide synchronously towards each other (moving towards the center of the box).

[0038] Slider 503 pulls the top of side plate 2 horizontally back into the box via hinge 504. Under the constraint of bottom rotation, side plate 2 gradually flips inward around the bottom axis from a vertical position and tilts down. Side plate 2 tilts completely to a horizontal position and is stacked on top of side plate 3. Top plate 4 moves to its lowest position with slider 503, and the entire box is compressed into a flat shape. At this time, the thread self-locking characteristic of the bidirectional threaded rod 502 keeps the folded state stable, which is convenient for empty box return or stacking storage.

[0039] After unfolding or folding, rotate the handle 604 in the opposite direction to separate the limiting plate 605, and the geared motor 7 can be taken out from the limiting frame 601. The geared motor 7 can be used as a general power source for the operation of the next folding box, realizing multiple uses of one machine and reducing equipment costs.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
