[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the amount used has always been the first among various packaging products. In addition to protecting goods, facilitating storage and transportation, it also plays a role in beautifying and promoting goods; for products such as glass packaging and electronic equipment, corrugated boxes are mostly used as packaging to meet transportation needs. Corrugated boxes can have good adsorption with tape, so tape is usually used to complete the sealing, but when the external environment temperature is low, the tape is easy to detach from the surface of the corrugated box. When unpacking, it is necessary to use a knife to tear off the tape, which is also easy to damage the corrugated box. There are problems such as unstable sealing, time-consuming and labor-intensive unpacking, and difficulty in achieving reuse; in addition, when the handling is out of hand, bumps during transportation, etc., it will cause impact on the bottom of the corrugated box.

The inner diameter of the capillary tube restricts the rate at which the hydraulic oil enters the second piston cylinder. When the hydraulic oil enters the second piston cylinder, the compressed gas is further compressed, increasing the pressure of the compressed gas. As a result, the air pressure of the compressed gas inhibits the second piston from approaching the compressed gas, buffering the buffer plate and preventing the product from being cracked. Moreover, by driving the screw to rotate clockwise or counterclockwise through the turntable, the turntable can be raised or lowered. The turntable gradually moves away from or approaches the second piston rod, and the third piston can expand or contract the compressed gas space, causing the air pressure of the compressed gas to decrease or increase. The buffering force is adjusted according to the weight of the product to achieve the purpose of product buffering and reduce the breakage rate of the product during handling or transportation.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The present invention provides a technical solution: a corrugated cardboard box that can be buffered and partitioned, as Figures 1-9 shown, including a corrugated cardboard box 1, four corner protectors 2, two first folding pages 3 and two second folding pages 4. The four corner protectors 2 are respectively fixedly connected to the four corners of the bottom of the corrugated cardboard box 1 to protect the bottom corners of the corrugated cardboard box 1 through the corner protectors 2. The two first folding pages 3 are integrally formed at the front and rear ends of the top of the corrugated cardboard box 1 respectively, and the two second folding pages 4 are integrally formed at the left and right ends of the top of the corrugated cardboard box 1 respectively. The top of the corrugated cardboard box 1 can be closed by bending the first folding pages 3 and the second folding pages 4 inward. A buffer mechanism 5 is installed at the bottom of the inner cavity of the corrugated cardboard box 1, and a buffer plate 6 is installed on the top of the buffer mechanism 5 to place the product through the buffer plate 6. Capping mechanisms 7 are installed at positions close to the upper surfaces of the two second folding pages 4 to lock the two second folding pages 4 through the capping mechanisms 7. An inner lining 8 is inserted into the inner cavity of the corrugated cardboard box 1. The inner lining 8 is made of foam material to prevent the product from being collided. Limiting grooves 9 are provided on the front and rear inner walls of the inner lining 8 from left to right. A first partition board 10 is inserted into the inner cavity of the limiting groove 9. The number of the first partition boards 10 is several. Slots are equidistantly provided on the outer wall of the first partition board 10 from front to back, and a second partition board 11 is inserted into the inner cavity of the slot. The inner cavity of the corrugated cardboard box 1 is partitioned by the cooperation of the first partition board 10 and the second partition board 11 to achieve the purpose of storing the products separately and prevent the products from colliding with each other and being damaged.

[0029] In a further embodiment, as Figure 4As shown in the figure, the buffer mechanism 5 includes a base 51 embedded in the center of the bottom of the inner cavity of the corrugated cardboard box 1. A positioning blind hole 52 is provided at the bottom center of the base 51. A screw rod 53 is screwed on the inner wall of the base 51. The top of the screw rod 53 is fixedly connected to a turntable 54. When the screw rod 53 rotates clockwise or counterclockwise, the turntable 54 can be raised or lowered. The turntable 54 is conical in shape. A braking rod 55 that can slide up and down is inserted into the center positions of the turntable 54 and the screw rod 53. Under the action of its own gravity, the braking rod 55 enters the inner cavity of the positioning blind hole 52 to brake the screw rod 53. The outer wall of the braking rod 55 and the inner wall of the positioning blind hole 52 are both regular polygons. As the screw rod 53 rotates, the braking rod 55 can enter the positioning blind hole 52 from multiple angles to achieve multi-angle braking of the screw rod 53. Support components 56 are installed at the four corners of the bottom of the inner cavity of the corrugated cardboard box 1, and pressure components 57 are installed on the diagonals of the bottom of the inner cavity of the corrugated cardboard box 1. Both ends of the pressure component 57 are respectively connected to the turntable 54 and the support component 56.

[0030] In a further embodiment, as Figure 5 shown, the support component 56 includes a first piston cylinder 561 vertically installed at the bottom corner of the inner cavity of the corrugated cardboard box 1. The inner cavity of the first piston cylinder 561 is filled with hydraulic oil 562. The hydraulic oil 562 serves as a buffer medium and is more stable than the traditional spring buffer. A first piston 563 is inserted into the top of the inner cavity of the first piston cylinder 561. One end of a first piston rod 564 is installed at the top of the first piston 563. The other end of the first piston rod 564 is installed with a mounting plate 565, and the top of the mounting plate 565 is installed with the bottom of the buffer plate 6. One end of a capillary tube 566 is installed at the bottom end of the outer wall of the first piston cylinder 561. The capillary tube 566 has the characteristic of a small inner diameter. The hydraulic oil 562 has viscosity. The capillary tube 566 can slow down the flow of the hydraulic oil 562 to buffer the descent of the first piston 563.

[0031] In a further embodiment, as Figure 5 and Figure 6As shown, the pressurizing assembly 57 includes a second piston cylinder 571 installed on the diagonal line of the bottom of the inner cavity of the corrugated paper box 1. The outer side of the second piston cylinder 571 is connected to the capillary 566. The outer side of the inner cavity of the second piston cylinder 571 is plugged with a second piston 572. The inner cavity of the second piston cylinder 571 is filled with compressed gas 573. The second piston 572 is pushed to squeeze the hydraulic oil 562 under the pressure of the compressed gas 573. The compressed gas 573 is used to provide power for the hydraulic oil 562 to move. The compressed gas 573 is nitrogen, which is an inert gas. The compressed gas 573 is a kind of hot gas, which has a small volume change due to thermal expansion and contraction and is not easy to generate heat, so the air pressure of the compressed gas 573 is prevented from changing when in use. The third piston 574 is inserted into the inner side of the inner cavity of the second piston cylinder 571, and one end of the second piston rod 575 is installed on the inner side of the third piston 574. The other end of the second piston rod 575 is in contact with the turntable 54. Since the turntable 54 is conical in shape, as the turntable 54 descends, the turntable 54 can squeeze the second piston rod 575 outward, thereby allowing the third piston 574 to move and reducing the space for the compressed gas 573.

[0032] In a further embodiment, Figure 2 As shown, the covering mechanism 7 includes a positioning plate 71 equidistantly installed on the upper surface of the second hinge 4 from front to back, the positioning plate 71 is mushroom-shaped, and a positioning portion 72 is installed on the upper surface of the second hinge 4, and the two positioning portions 72 are far away from each other and are in the same straight line with the positioning plate 71. The inner cavity of the positioning portion 72 is clamped with a sealing portion 73, and the sealing portion 73 is cross-wound on the outer wall of the positioning plate 71, so as to lock the two second hinges 4.

[0033] In a further embodiment, Figure 8 As shown, the positioning portion 72 includes a support seat 721 installed on the upper surface of the second folding leaf 4, and the support seat 721 and the positioning plate 71 are on the same straight line. A through groove 722 is opened on the upper surface of the support seat 721 along the left and right directions, and the sealing portion 73 is clamped through the through groove 722. Arc grooves 723 connected to the through groove 722 are opened on both sides of the left and right sides of the support seat 721.

[0034] In a further embodiment, Figure 9 As shown, the sealing portion 73 includes a nylon rope 731 cross-wound around the outer wall of the positioning disk 71. The surface of the nylon rope 731 is rough and has strong friction to prevent the nylon rope 731 from slipping against the positioning disk 71. A number of beads 732 are equidistantly installed on the outer wall of the nylon rope 731. The beads 732 are inserted into the inner cavity of the through groove 722 to clamp the nylon rope 731. The depth and height of the arc groove 723 are greater than the radius of the beads 732. When the beads 732 are inserted into the arc groove 723, they are pulled by the nylon rope 731 and will not fall out of the arc groove 723.

[0035] Working principle:

[0036] Step 1: According to the product specifications, insert the first partition 10 into the limit slot 9 at the corresponding position, and insert the second partition 11 into the slot at the corresponding position. Divide the space of the corrugated cardboard box 1 by the first partition 10 and the second partition 11 to store the product.

[0037] Step 2: Close the first folding page 3, and then close the second folding page 4. Use the nylon rope 731 to wind around the outer wall of the positioning disk 71 in a left-right cross pattern. Place the pull bead 732 into the through slot 722 and the arc slot 723 to clamp the nylon rope 731, realizing the closure of the corrugated cardboard box 1 and replacing the traditional tape sealing of the box.

[0038] When it is necessary to open the box, take out the pull bead 732 from the through slot 722 and the arc slot 723, and move the nylon rope 731 away from the positioning disk 71, then the corrugated cardboard box 1 can be opened.

[0039] Step 3: When carrying the corrugated cardboard box 1 or during transportation when it is jolted, due to the influence of the product gravity, the buffer plate 6 descends. At the same time, the first piston 563 moves downward to squeeze the hydraulic oil 562. Affected by the inner diameter of the capillary tube 566, the flow rate of the hydraulic oil 562 passing through the capillary tube 566 is slowed down. The hydraulic oil 562 pushes the second piston 572 to move and squeeze the compressed gas 573. The volume of the compressed gas 573 becomes smaller and the air pressure increases, providing a reverse acting force to the second piston 572 to buffer the descent of the first piston 563 and prevent the product from being damaged by the impact force.

[0040] Step 4: When it is necessary to adjust the buffering effect according to the product weight, remove the buffer plate 6, lift the brake lever 55 to move the brake lever 55 out of the positioning blind hole 52, and rotate the screw 53 clockwise or counterclockwise. The turntable 54 rises or falls. When the turntable 54 rises, the turntable 54 gradually moves away from the second piston rod 575, the space of the compressed gas 573 increases and the air pressure drops. When the turntable 54 descends, the inclined surface of the turntable 54 extrudes the second piston rod 575 outward, and the third piston 574 squeezes the compressed gas 573, and the air pressure of the compressed gas 573 increases. When the screw 53 stops rotating, insert the brake lever 55 into the positioning blind hole 52 to position the screw 53, and the buffering effect can be adjusted according to the product weight.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
