DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is 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.

[0027] The present invention provides a technical solution: a corrugated paper box capable of buffering and partitioning, such as Figure 1-Figure 9 As shown, it includes a corrugated paper box 1, four corner guards 2, two first folding pages 3 and two second folding pages 4. The four corner guards 2 are respectively fixedly connected to the four corners of the bottom of the corrugated paper box 1, and the bottom corners of the corrugated paper box 1 are protected by the corner guards 2. The two first folding pages 3 are respectively integrally formed at the front and rear ends of the top of the corrugated paper box 1, and the two second folding pages 4 are respectively integrally formed at the left and right ends of the top of the corrugated paper box 1. The top of the corrugated paper box 1 can be closed by bending the first folding pages 3 and the second folding pages 4 inwardly. A buffer mechanism 5 is installed at the bottom of the inner cavity of the corrugated paper box 1, and a buffer plate 6 is installed on the top of the buffer mechanism 5. Products are placed by the buffer plate 6. The two second A covering mechanism 7 is installed at a position close to the upper surface of the folding leaf 4, and the two second folding leaves 4 are locked by the covering mechanism 7. A liner 8 is inserted into the inner cavity of the corrugated cardboard box 1, and the liner 8 is made of foam material to prevent the product from collision. Limiting grooves 9 are provided on the front and rear inner walls of the liner 8 from left to right, and a first partition 10 is inserted into the inner cavity of the limiting groove 9. There are several first partitions 10, and slots are equidistantly provided on the outer wall of the first partition 10 from front to back, and second partitions 11 are inserted into the inner cavity of the slots. The first partition 10 and the second partition 11 cooperate to divide the inner cavity of the corrugated cardboard box 1, so as to achieve the purpose of storing products separately and prevent products from colliding with each other and being damaged.

[0028] In a further embodiment, Figure 4As shown, the buffer mechanism 5 includes a base 51 embedded in the center of the bottom of the inner cavity of the corrugated paper box 1, a positioning blind hole 52 is opened at the bottom of the center of the base 51, a screw 53 is screwed to the inner wall of the base 51, and a turntable 54 is fixedly connected to the top of the screw 53. When the screw 53 rotates clockwise or counterclockwise, the turntable 54 can be raised or lowered. The turntable 54 is conical in shape. A brake rod 55 that can slide up and down is inserted at the center of the turntable 54 and the screw 53. The brake rod 55 is supported by its own gravity. Under the action, the brake rod 55 enters the inner cavity of the positioning blind hole 52 to brake the screw 53. The outer wall of the brake rod 55 and the inner wall of the positioning blind hole 52 are both regular polygons. As the screw 53 rotates, the brake rod 55 can enter the positioning blind hole 52 from multiple angles to achieve multi-angle braking of the screw 53. Support components 56 are installed at the four corners of the bottom of the inner cavity of the corrugated cardboard box 1, and pressurizing components 57 are installed on the diagonals of the bottom of the inner cavity of the corrugated cardboard box 1. The two ends of the pressurizing component 57 are respectively connected to the turntable 54 and the support component 56.

[0029] In a further embodiment, Figure 5 As shown, the support assembly 56 includes a first piston cylinder 561 vertically installed at the bottom corner of the inner cavity of the corrugated box 1, the inner cavity of the first piston cylinder 561 is filled with hydraulic oil 562, and the hydraulic oil 562 serves as a buffer medium, which is more stable than the traditional spring buffer. A first piston 563 is inserted at the top of the inner cavity of the first piston cylinder 561, and one end of a first piston rod 564 is installed on the top of the first piston 563. A mounting plate 565 is installed on the other end of the first piston rod 564, and the top of the mounting plate 565 is installed at the bottom of the buffer plate 6. One end of a capillary 566 is installed at the bottom end of the outer wall of the first piston cylinder 561. The capillary 566 has a small inner diameter. The hydraulic oil 562 is viscous. The capillary 566 can slow down the flow of the hydraulic oil 562, so that the descent of the first piston 563 is buffered.

[0030] In a further embodiment, 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.

[0031] 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.

[0032] 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.

[0033] In a further embodiment, Fig. 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.

[0034] Working principle: Step 1: According to the product specifications, the first partition 10 is inserted into the limiting groove 9 at the corresponding position, and the second partition 11 is inserted into the slot at the corresponding position, and the space of the corrugated box 1 is divided by the first partition 10 and the second partition 11 to store the product; Step 2: close the first folding leaf 3, then close the second folding leaf 4, use the nylon rope 731 to cross-wrap around the outer wall of the positioning plate 71, put the pull bead 732 into the through groove 722 and the arc groove 723, and clamp the nylon rope 731 to close the corrugated paper box 1, replacing the traditional tape sealing; When it is necessary to open the corrugated paper box 1, the pull bead 732 is taken out from the through groove 722 and the arc groove 723, and the nylon rope 731 is moved away from the positioning plate 71, so that the corrugated paper box 1 can be opened; Step 3: When the corrugated box 1 is being carried or bumped during transportation, the buffer plate 6 is lowered due to the gravity of the product. At the same time, the first piston 563 moves downward to squeeze the hydraulic oil 562. Under the influence of the inner diameter of the capillary 566, the flow of the hydraulic oil 562 through the capillary 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 decreases, and the air pressure increases, providing a reverse force to the second piston 572, buffering the descent of the first piston 563, and preventing the product from being damaged by the impact force. Step 4. When it is necessary to adjust the buffering effect according to the weight of the product, remove the buffer plate 6, lift the brake rod 55, move the brake rod 55 out of the positioning blind hole 52, and let the screw 53 rotate clockwise or counterclockwise, and 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 decreases. When the turntable 54 descends, the inclined surface of the turntable 54 squeezes the second piston rod 575 outward, and the third piston 574 squeezes the compressed gas 573. The air pressure of the compressed gas 573 increases. When the screw 53 stops rotating, the brake rod 55 is inserted into the positioning blind hole 52 to position the screw 53, so that the buffering effect can be adjusted according to the weight of the product.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
