Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box technology, and specifically to a deformable, highly stable corrugated cardboard box. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products. Corrugated boxes are considered green and environmentally friendly products, benefiting both environmental protection and ease of loading, unloading, and transportation.

[0003] Chinese invention patent application number 201811312369.0 discloses a green and environmentally friendly corrugated cardboard box, comprising a side panel forming a square shape and end caps No. 1 and No. 2 that fit over the square-shaped side panel; each of the end caps No. 1 and No. 2 has two specifications, one specification of which fits the side panel before deformation, and the other specification of which fits the side panel after deformation; the side panel is divided into two symmetrically arranged end caps No. 1 and No. 2 by four fold lines. The system comprises a first plate and two symmetrically arranged second plates; each first plate has a second crease parallel to the first crease and of equal length, and the second creases on the two first plates are symmetrical about the center of the U-shaped side plate; four hinge mechanisms are embedded in the side plate; one end of each hinge mechanism is provided with a chamber and a wire hole connecting the chamber to the outside, wherein two hinge mechanisms are located at the first crease and the other two hinge mechanisms are located at the second crease; the hinge mechanism includes a piston head, a spring, a pull rope, and a third and a fourth plate that are hinged to each other;

[0004] While this invention can change the shape of corrugated cardboard boxes, the possible changes are limited. Furthermore, the creases are reinforced with glue, which causes them to stick together, limiting the number of times the boxes can be reshaped. The glue's reinforcing strength is also limited, making the boxes prone to flattening during use. When transporting fragile items, a wooden frame is required, increasing packaging volume, making transportation inconvenient, and resulting in high packaging costs. Summary of the Invention

[0005] The purpose of this invention is to address the problems of corrugated cardboard boxes having limited design variations, being unable to undergo multiple shape changes, being inconvenient to use, having low strength, and requiring additional wooden frames for transporting fragile items. This invention provides a deformable, highly stable corrugated cardboard box.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A deformable, highly stable corrugated cardboard box includes a corrugated cardboard box with creases on all four sides of its inner side. The inner walls of the creases are provided with an inner crease plate one and an inner crease plate two, which are symmetrically distributed. Both inner crease plates one and two have rope holes inside. Tightening ropes are provided on the outer sides of both inner crease plates one and two. The tightening rope on the outer side of inner crease plate one passes through the rope hole inside inner crease plate two, and the tightening rope on the outer side of inner crease plate two passes through the rope hole inside inner crease plate one.

[0008] It also includes a reinforcing mechanism located inside the crease, which can tighten the tightening rope.

[0009] Furthermore, the reinforcing mechanism includes a reinforcing column disposed inside the crease, a transmission hole being provided inside the reinforcing column, a rotatable shaft being disposed inside the transmission hole, a winding wheel being disposed outside the rotating shaft, the winding wheel being connected to a tightening rope, and the tightening ropes on the outer sides of the first inner crease plate and the second inner crease plate being respectively connected to both sides of the winding wheel.

[0010] Furthermore, an active threaded hole is provided on the upper part of the inner wall of the transmission hole, and an active screw is threadedly connected to the inside of the active threaded hole. A cross screwdriver groove is provided on the top of the active screw, and a keyway is provided inside the active screw. A shaft key is provided on the outer side of the rotating shaft and slidably connected in the keyway.

[0011] Furthermore, a pressure ring is provided at the bottom of the active screw, and sliding holes are provided on both sides of the inner wall of the transmission hole to penetrate the reinforcing column. A locking block is slidably connected inside the sliding hole, and a compression spring is provided between the locking block and the inner wall of the sliding hole. The radius of the pressure ring is larger than the radius of the active screw, and the pressure ring can push the locking block to slide when it descends. The outer sides of the inner crease plate 1 and the inner crease plate 2 are provided with locking holes for inserting the locking block.

[0012] Furthermore, a driven threaded hole is provided at the bottom of the inner wall of the transmission hole, and a driven screw is threadedly connected inside the driven threaded hole. A pressure ring is provided at the bottom of the driven screw. Sliding holes are provided on both sides of the inner wall of the transmission hole, penetrating the reinforcing column. A locking block is slidably connected inside the sliding hole. A compression spring is provided between the locking block and the inner wall of the sliding hole. The radius of the pressure ring is larger than the radius of the driven screw, and the pressure ring can push the locking block to slide when it descends. Locking holes for inserting the locking block are provided on the outer sides of both the inner crease plate and the inner crease plate.

[0013] Furthermore, the tops of both the first and second card blocks are designed to be angled.

[0014] Furthermore, both sides of the crease are concave inward at a 45° angle.

[0015] Furthermore, the cross-section of the reinforcing column is an isosceles right triangle, and it can be completely inserted into the straight crease.

[0016] Furthermore, the outer side of the reinforcing column is provided with a rope groove for receiving the tightening rope.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention, by providing creases on all four sides of the inner side of the corrugated cardboard box, allows the corrugated cardboard box to be transformed into any shape as needed, thus having a wide range of applications.

[0019] 2. In this invention, the reinforcing mechanism is removed from the crease, and then the tightening rope is tightened by the reinforcing mechanism. The two sets of tightening ropes tighten each other, causing the inner plate of the crease one and the inner plate of the crease two to move closer and closer together, thereby causing the corrugated cardboard box to bend from other positions and change the shape of the corrugated cardboard box. At this time, the reinforcing mechanism is located at the bending point of the corrugated cardboard box and strengthens the bending point. By driving the reinforcing mechanism at different positions, the corrugated cardboard box can change its shape multiple times, which is convenient to use.

[0020] 3. The present invention provides creases on all four sides of the inner side of the corrugated cardboard box, and reinforces the creases with reinforcing mechanisms. The reinforcing mechanisms strengthen the overall structure of the corrugated cardboard box, improving its transport stability. No additional wooden frame is required, resulting in low transportation costs. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figures 1-12 As shown, a deformable, highly stable corrugated cardboard box includes a corrugated cardboard box 1. Creases 2 are provided around the inner perimeter of the corrugated cardboard box 1. A first crease inner plate 3 and a second crease inner plate 4 are provided on the inner wall of the creases 2. The first crease inner plate 3 and the second crease inner plate 4 are symmetrically distributed. A rope hole 5 is provided inside both the first crease inner plate 3 and the second crease inner plate 4. A tightening rope 6 is provided on the outer side of both the first crease inner plate 3 and the second crease inner plate 4. The tightening rope 6 on the outer side of the first crease inner plate 3 passes through the rope hole 5 inside the second crease inner plate 4, and the tightening rope 6 on the outer side of the second crease inner plate 4 passes through the rope hole 5 inside the first crease inner plate 3.

[0036] It also includes a reinforcing mechanism located inside the crease 2, which can tighten the tightening rope 6.

[0037] When in use, creases 2 are provided on all four sides of the inside of the corrugated cardboard box 1, and a reinforcing mechanism is provided in the creases 2. The reinforcing mechanism forms the internal skeleton of the corrugated cardboard box 1, thereby strengthening the overall structure of the corrugated cardboard box and improving the transportation stability of the corrugated cardboard box 1. No additional wooden frame is required, and the transportation cost is low.

[0038] When the shape of the corrugated cardboard box 1 needs to be changed, the reinforcing mechanism is pulled away from the crease 2. At the same time, the reinforcing mechanism drives the tightening rope 6 to tighten. The tightening rope 6 on the inner crease plate 1 3 is tightened by the reinforcing mechanism through the rope hole 5 inside the inner crease plate 2 4. The tightening rope 6 on the inner crease plate 2 4 is tightened by the reinforcing mechanism through the rope hole 5 inside the inner crease plate 1 3. At this time, the two sets of tightening ropes 6 are brought together on the outside of the reinforcing mechanism. The inner crease plate 1 3 and the inner crease plate 2 4 are brought together by the action of the two sets of tightening ropes 6, and a crease is formed at this point. At the same time, the reinforcing mechanism at the original bend is released, so that the reinforcing mechanism relaxes the tightening rope 6. The tightening rope 6 automatically unfolds under the action of the return spring 21. At this time, the inner crease plate 1 3 and the inner crease plate 2 4 are unrestricted and can be unfolded flat. At this time, the reinforcing mechanism automatically inserts into the crease 2 under the action of the tension of the tightening rope 6, thereby completing the shape change of the corrugated cardboard box 1. Figure 11 As shown, with multiple creases 2, the corrugated cardboard box 1 can be changed into different shapes. By controlling the tightening length of the tightening rope 6, the bending angle at the crease 2 can be changed, allowing the corrugated cardboard box 1 to form a circle, such as... Figure 12 As shown, the deformation capability of corrugated cardboard box 1 is further improved;

[0039] When it is necessary to switch the shape of the corrugated cardboard box 1 again, release the reinforcing mechanism at the bend, so that the reinforcing mechanism relaxes the tightening rope 6. The tightening rope 6 automatically extends under the action of the return spring 21. At this time, the inner crease plate 1 3 and the inner crease plate 2 4 are unrestricted and can be unfolded flat. Then move the reinforcing mechanism in other positions, and the corrugated cardboard box can continue to deform. The reinforcing mechanism at the bend is close to the bend position, which strengthens the bend position and prevents it from breaking. At the same time, the reinforcing mechanism will be tightly attached to the crease 2 under the action of the reaction force of the tightening rope 6. There is no need to use glue to reinforce the bend, which is convenient to use.

[0040] like Figures 2-4 As shown, in some embodiments, the reinforcing mechanism includes a reinforcing column 7 disposed inside the crease 2. The reinforcing column 7 has a transmission hole inside, and a rotating shaft 9 is disposed inside the transmission hole. A winding wheel 10 is disposed outside the rotating shaft 9. The winding wheel 10 is connected to the tightening rope 6. The tightening ropes 6 on the outer sides of the inner crease plate 1 3 and the inner crease plate 2 4 are respectively connected to both sides of the winding wheel 10.

[0041] By rotating the shaft 9, the shaft 9 drives the roller 10 to rotate, and the roller 10 winds up two sets of tightening ropes 6. The two sets of tightening ropes 6 gather the inner fold panel 3 and the inner fold panel 4 together, and the corrugated cardboard box 1 is bent. At the same time, the bending of the corrugated cardboard box 1 can squeeze the reinforcing column 7 out of the fold 2, making bending convenient. When it is necessary to flatten the bent part, the shaft 9 is reversed, and the shaft 9 drives the roller 10 to reverse. The roller 10 loosens the tightening ropes 6, and the return spring 21 drives the tightening ropes 6 to unfold. The tightening ropes 6 then unfold the fold 2, and the control is stable.

[0042] like Figure 7 , Figure 8 As shown, in some embodiments, an active threaded hole is provided above the inner wall of the transmission hole, and an active screw 8 is threadedly connected inside the active threaded hole. A cross screwdriver groove is provided on the top of the active screw 8, and a keyway is provided inside the active screw 8. A shaft key is provided on the outer side of the rotating shaft 9 and slidably connected in the keyway.

[0043] By rotating the drive screw 8, the drive screw 8 drives the rotating shaft 9 to rotate via the shaft key and keyway. The drive screw 8 can slide relative to the rotating shaft 9, ensuring stable transmission. The rotating shaft 9 drives the winding wheel 10 to rotate, and the winding wheel 10 controls the tension of the tightening rope 6. Under the self-locking action of the drive screw 8, when the drive screw 8 stops rotating, the tightening rope 6 will not automatically unwind, ensuring stable adjustment. It can also adjust the bending angle at the crease 2 to improve the deformation capability of the corrugated cardboard box 1. While bending, the reinforcing column 7 can be tightly attached to the bending point to support it, ensuring stable support.

[0044] like Figure 8 As shown, in some embodiments, a pressure ring 11 is provided at the bottom of the active screw 8, and sliding holes 1 through the reinforcing column 7 are provided on both sides of the inner wall of the transmission hole. A locking block 12 is slidably connected inside the sliding hole 1, and a compression spring 13 is provided between the locking block 12 and the inner wall of the sliding hole 1. The radius of the pressure ring 11 is larger than the radius of the active screw 8, and the pressure ring 11 can push the locking block 12 to slide when it descends. The outer sides of the crease inner plate 1 3 and the crease inner plate 2 4 are provided with locking holes 18 that can be inserted into the locking block 12.

[0045] When crease 2 is needed, rotate the drive screw 8. Drive screw 8 rises under the action of drive thread hole. Drive screw 8 drives pressure ring 11 to rise. Pressure ring 11 rises away from locking block 12. Locking block 12 slides along sliding hole 1 into transmission hole under the action of compression spring 13. At this time, locking block 12 moves away from locking hole 18. Reinforcing column 7 separates from crease inner plate 1 3 and crease inner plate 2 4. Since drive screw 8 rotates less and winding wheel 10 rotates less, the moving distance of tightening rope 6 is small. Therefore, under the action of tightening rope 6's own elasticity, the structure will not be disturbed and the operation is stable. Then continue to rotate drive screw 8. Drive screw 8 drives rotating shaft 9 to rotate through shaft key and keyway. Drive screw 8 can slide relative to rotating shaft 9. The transmission is stable. Rotating shaft 9 drives winding wheel 10 to rotate. Winding wheel 10 winds up tightening rope 6. Tightening rope 6 drives crease inner plate 1 3 and crease inner plate 2 4 to bend.

[0046] When it is necessary to unlock crease 2, reverse the drive screw 8. The drive screw 8 descends under the action of the drive threaded hole, driving the pressure ring 11 to descend. The descending pressure ring 11 pushes the locking block 12 to slide. The locking block 12 extends along the sliding hole. Then continue to rotate the drive screw 8. The drive screw 8 drives the rotating shaft 9 to rotate through the shaft key and keyway. The drive screw 8 can slide relative to the rotating shaft 9, and the transmission is stable. The rotating shaft 9 drives the winding wheel 10 to rotate. The winding wheel 10 loosens the tightening rope 6. Under the action of the return spring 21, the tightening rope 6 automatically unwinds. At this time, the rope can be... As crease 2 unfolds, the tightening rope 6 moves the reinforcing column 7 into crease 2. At this time, the locking block 12 engages with the locking holes 18 on the inner crease plate 3 and the inner crease plate 4 respectively. The tightening rope 6 and the reinforcing column 7 prevent crease 2 from bending outward. The locking block 12 and the locking hole 18 prevent the reinforcing column 7 from automatically separating from the inner crease plate 3 and the inner crease plate 4. The reinforcing column 7 also restricts crease 2 from bending inward, thus ensuring that crease 2 remains stable when it is flat, and the corrugated cardboard box 1 has a stable structure.

[0047] like Figure 9 As shown, in some embodiments, a driven threaded hole is provided at the bottom of the inner wall of the transmission hole, and a driven screw 14 is threadedly connected inside the driven threaded hole. A pressure ring 15 is provided at the bottom of the driven screw 14. Sliding holes 2 that penetrate the reinforcing column 7 are provided on both sides of the inner wall of the transmission hole. A locking block 2 16 is slidably connected inside the sliding hole 2. A compression spring 2 17 is provided between the locking block 2 16 and the inner wall of the sliding hole 2. The radius of the pressure ring 2 15 is larger than the radius of the driven screw 14, and the pressure ring 2 15 can push the locking block 2 16 to slide when it descends. The outer sides of the folded inner plate 1 3 and the folded inner plate 2 4 are provided with locking holes 2 19 that can be inserted into the locking block 2 16.

[0048] When crease 2 is needed, rotate the drive screw 8. Driven by the drive threaded hole, the drive screw 8 rises, causing the pressure ring 11 to rise. The pressure ring 11 rises away from the locking block 12. Under the action of the compression spring 13, the locking block 12 slides along the sliding hole into the transmission hole. At this time, the locking block 12 moves away from the locking hole 18. Simultaneously, the drive screw 8 drives the driven screw 14 to rotate via the rotating shaft 9. The driven screw 14 rises under the action of the driven threaded hole. The pressure ring 15 is moved away from the locking block 16. Under the action of the pressure spring 17, the locking block 16 is moved away from the locking hole 19. The reinforcing column 7 is separated from the inner crease plate 3 and the inner crease plate 4. Then the driving screw 8 continues to rotate. The driving screw 8 drives the rotating shaft 9 to rotate through the shaft key and keyway. The driving screw 8 can slide relative to the rotating shaft 9. The transmission is stable. The rotating shaft 9 drives the winding wheel 10 to rotate. The winding wheel 10 winds up the tightening rope 6. The tightening rope 6 causes the inner crease plate 3 and the inner crease plate 4 to bend.

[0049] When it is necessary to unlock crease 2, reverse the drive screw 8. The drive screw 8 descends under the action of the drive threaded hole, driving the pressure ring 11 to descend. The descending pressure ring 11 pushes the locking block 12 to slide, and the locking block 12 extends along the sliding hole. At the same time, the drive screw 8 drives the driven screw 14 to rotate through the rotating shaft 9. The driven screw 14 descends under the action of the driven threaded hole, driving the pressure ring 15 to descend. The descending pressure ring 15 pushes the locking block 16 to extend. Then continue to rotate the drive screw 8. The drive screw 8 drives the rotating shaft 9 to rotate through the shaft key and keyway, and the drive screw 8 can slide relative to the rotating shaft 9, ensuring stable transmission. The rotating shaft 9 drives the winding wheel 10 to rotate, and the winding wheel 10 loosens the tightening rope 6. Under the action of the return spring 21, the tightening rope 6 automatically unwinds, at which point the crease 2 can be unfolded. As the crease 2 unfolds, the tightening rope 6 moves the reinforcing column 7 into the crease 2. At this time, the first locking block 12 is respectively locked into the locking hole 18 on the inner crease plate 3 and the inner crease plate 4, and the second locking block 16 is respectively locked into the locking hole 19 on the inner crease plate 3 and the inner crease plate 4. Through the cooperation of the first locking block 12, the locking hole 18 and the second locking block 16, the two ends of the reinforcing column 7 can be fixed, making the connection more stable and the support more stable. The tightening rope 6 and the reinforcing column 7 can prevent the crease 2 from bending outward. The locking block 12 and the locking hole 18 can restrict the reinforcing column 7, so that the reinforcing column 7 will not automatically separate from the inner crease plate 3 and the inner crease plate 4. The reinforcing column 7 can also restrict the crease 2 from bending inward, thus ensuring that the crease 2 remains stable when it is flat, and the corrugated cardboard box 1 has a stable structure.

[0050] At the same time, the self-locking of the driven threaded hole and the driven screw 14 can lock the reel 10 a second time, ensuring the stability of the crease 2 and preventing the tightening rope 6 from unfolding automatically.

[0051] like Figure 8 , Figure 9 As shown, in some embodiments, the tops of both the first card block 12 and the second card block 16 are designed to be angled.

[0052] The inclined design of the tops of both the first and second locking blocks 12 and 2 makes the pressure rings 11 and 2 15 more stable when pushing the first and second locking blocks 12 and 2 16 down, preventing the mechanism from jamming.

[0053] like Figure 2 As shown, in some embodiments, both sides of the crease 2 are recessed inward at a 45° angle.

[0054] With both sides of crease 2 indented at 45°, the corrugated cardboard box 1 can be bent stably and maintain a right angle, allowing it to be reliably transformed into various rectangles. The transformation is stable, and the tilt angle of crease 2 can be changed according to needs, so that the corrugated cardboard box can be bent into various irregular shapes, thus expanding its application range.

[0055] like Figure 3 As shown, in some embodiments, the cross-section of the reinforcing column 7 is an isosceles right triangle and can be completely inserted into the straight crease 2.

[0056] The design of reinforcing column 7, with its cross-section being an isosceles direct triangle, allows it to be fully inserted into the straight crease 2. Figure 2 As shown, when the crease is flat, the reinforcing post 7 can be completely housed in the crease 2, which not only does not reduce the internal space of the corrugated cardboard box 1, but also provides stable support for the crease 2. When the crease 2 with 45° on both sides is bent, the crease 2 forms a right angle. At this time, the reinforcing post 7 can fit tightly at the right angle to support the bend and ensure that the structural strength at the crease 2 remains stable.

[0057] Meanwhile, when the crease 2 is not completely bent, the right-angled side of the reinforcing column 7 is inserted into the crease 2. Since the cross-section of the reinforcing column 7 is an isosceles right triangle, the reinforcing column 7 can always be located in the center of the crease 2, ensuring that the reinforcing column 7 is stable and will not cause the crease 2 to collapse to one side, thus ensuring structural stability.

[0058] like Figure 4 As shown, in some embodiments, the outer side of the reinforcing post 7 is provided with a rope groove 20 for receiving the tightening rope 6.

[0059] The design of the rope groove 20 makes the tightening rope 6 more stable when driven by the reinforcing column 7, while not affecting the reinforcing column 7's fit in the crease 2, ensuring stable storage. At the same time, when the crease 2 is fully bent, the two sets of tightening ropes 6 can be tightly closed in the rope groove 20, without affecting the reinforcing column 7's support for the crease 2, resulting in high support stability.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
