Description

Technical Field

[0001] This application relates to the technical field of cartons, and particularly to a high-strength corrugated carton. Background Art

[0002] Corrugated board is made into corrugated cartons through die-cutting, indentation, box nailing or gluing. Corrugated cartons are the most widely used packaging products, with the characteristics of low packaging cost, effective use of resources, easy recycling, no waste pollution, and low storage and transportation costs. Therefore, the consumption of corrugated cartons ranks first among various packaging products.

[0003] Currently, common corrugated cartons include a box body, which is a hollow shell with an open top. A box cover for covering the open top of the box body is rotatably arranged on the top of the box body.

[0004] Regarding the above related technology, the inventor believes that during the transportation process of corrugated cartons, two adjacent corrugated cartons are squeezed, causing the box body to be deformed or even damaged, thus affecting the items inside the carton. Utility Model Content

[0005] In order to reduce the deformation or even damage of the box body, this application provides a high-strength corrugated carton.

[0006] A high-strength corrugated carton provided by this application adopts the following technical solutions:

[0007] A high-strength corrugated carton includes a box body, which is a hollow shell with an open top. A box cover for covering the open top of the box body is rotatably arranged on the box body; it further includes a support assembly arranged on the box body. The support assembly includes a base for placing the box body. A number of support columns for supporting the box body, a number of moving columns for supporting the box body, and a clamping member for driving the moving columns to move and clamping the box body are arranged on the base.

[0008] By adopting the above technical solutions, the box body is used to place products, etc. The box cover is closed on the box body to form a relatively airtight space. The support assembly is used to support the bottom of the box body to prevent the bottom of the box body from being damaged due to excessive weight. The base provides an installation position for the box body. The support columns and moving columns support the box body to prevent the box body from swinging. The clamping member drives the box body to move. When the size of the box body changes, the box body can be clamped. The support columns and moving columns support the box body to prevent extrusion between two adjacent box bodies and reduce damage to the box body.

[0009] Optionally, the clamping member includes a fixing plate fixedly connected to the base. A number of sliding grooves are formed on the base. The moving columns are embedded in the sliding grooves and are slidably connected to the sliding grooves. A clamping spring is fixedly arranged between the fixing plate and the moving columns.

[0010] By adopting the above technical solution, before the installation process, move the moving column, and the moving column presses the clamping spring to make the clamping spring in a compressed state. Then, place the box between the support column and the moving column. Since the clamping spring is in a compressed state and generates an elastic force, the elastic force acts on the moving column, thereby pressing the box to prevent the box from moving.

[0011] Optionally, it further includes an adjusting assembly for increasing the heights of the support column and the moving column. The adjusting assembly includes an adjusting plate and a sliding member that relatively slides with both the support column and the moving column; connecting rods are hermetically arranged on both the support column and the moving column. The connecting rods pass through the support column or the moving column and are slidably connected to the support column or the moving column. The adjusting plate is fixedly connected to the connecting rods; a plurality of telescopic members are arranged between the sliding member and the base. The telescopic members include fixed tubes and sliding rods fixedly connected to the sliding member. The sliding rods pass through the fixed tubes and are slidably connected to the fixed tubes. Air pipes are arranged on the fixed tubes. One end of the air pipe is communicated with the air pipe, and the other end of the air pipe is communicated with the support column or the moving column.

[0012] By adopting the above technical solution, the adjusting assembly can increase the heights of the support column and the moving column, so that the support column and the moving column can support boxes of different heights. The sliding member is used to store the boxes, and the connecting rods are used to connect the adjusting plate and the support column or the adjusting plate and the moving column, and also drive the connecting rods to move. After placing the box on the sliding member, due to the gravity of the box moving in the direction close to the ground, the sliding rod moves along the direction of the fixed tube, and the gas in the fixed tube flows into the support column or the moving column along the air pipe. The gas in the support column and the moving column increases, thereby pushing the connecting rod to move in the direction away from the ground. The movement of the connecting rod drives the adjusting plate to move, thereby increasing the heights of the support column and the moving column, so that the support assembly can adapt to boxes of different heights.

[0013] Optionally, a return spring for returning the sliding rod to its initial position is arranged in the fixed tube.

[0014] By adopting the above technical solution, when the box is placed on the sliding member, the sliding member presses the telescopic rod, causing the telescopic rod to move towards the end of the fixed tube close to the bottom. The sliding rod presses the return spring to make the return spring in a compressed state. The return spring compresses to generate an elastic force. When the box is removed from the sliding member, under the action of the return spring, the sliding rod moves, causing the sliding member to return to its initial position.

[0015] Optionally, the sliding member includes a support plate connected to at least two of the support columns and a connecting plate connected to at least two of the moving columns. The support plate is slidably connected to the connecting plate.

[0016] By adopting the above technical solution, when the carton is clamped by the clamping member, the distance between the pillar and the movable column changes, and the connecting plate moves along the distance of the support plate, so that the sliding member adjusts the length of the sliding member according to the distance between the pillar and the movable column, which facilitates the use of the clamping member.

[0017] Optionally, the connecting rod is provided with scale lines for measuring the weight of the box.

[0018] By adopting the above technical solution and setting a scale on the connecting rod, the operator can estimate the weight of the box according to the distance that the connecting rod extends out of the support.

[0019] Optionally, a mounting groove is provided at the bottom of the base, and a moving component for pushing the supporting component to move is provided at the bottom of the base, and the moving component includes a rotating shaft arranged in the mounting groove and rotatably connected to the base, a mounting plate fixedly connected to the rotating shaft, a rotating wheel rotatably connected to the mounting plate, and a limit member for limiting the rotation of the rotating shaft.

[0020] By adopting the above technical solution, the moving component is used to push the supporting component to move, and the limiting member is used to limit the movement of the rotating shaft. When the box needs to be moved, the rotating wheel is rotated to make the rotating wheel fit the ground, and then the movement of the rotating shaft is limited by the limiting member, thereby pushing the supporting component to move; when the box does not need to be moved, the rotating wheel is rotated to place the moving component in the installation groove to avoid damage to the moving component.

[0021] Optionally, a fixing groove connected to the mounting groove is provided on the base, a limiting groove is provided on the side wall of the fixing groove, and a yield groove is provided on the rotating shaft; the limiting member includes a sliding plate embedded in the limiting groove and slidably connected to the limiting groove, a fixing rod passed through the fixing groove and fixedly connected to the sliding plate, and a limiting spring is fixedly provided on one end of the sliding plate away from the rotating shaft.

[0022] By adopting the above technical solution, the limiter is used to limit the movement of the sliding plate. When the position of the moving component needs to be adjusted, the fixed rod is pulled to the side away from the rotating shaft. The sliding plate moves with the movement of the fixed rod, thereby pressing the limit spring to put the limit spring in a compressed state. After adjusting the position of the moving component, the fixed rod is released so that the fixed rod fixes the rotating shaft.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The support assembly supports the box to avoid squeezing between two adjacent boxes and reduce damage to the box;

[0025] 2. The adjusting component can increase the heights of the support pillar and the moving column. After placing the box body on the sliding member, under the action of the self-gravity of the box body, the sliding member moves. Under the action of the telescopic member, the adjusting plate moves to support the side wall of the box body, enabling the support component to adapt to box bodies of different heights;

[0026] 3. When the box body needs to be moved, rotate the rotating wheel to make the rotating wheel contact the ground. Then, limit the movement of the rotating shaft through the limiting member, thereby pushing the support component to move; when the box body does not need to be moved, rotate the rotating wheel and place the moving component in the installation groove to avoid damage to the moving component and facilitate the operator to move the box body.

[0034] The following further Figures 1-6 describes the present application in detail with reference to the accompanying drawings.

[0035] This embodiment of the present application discloses a high-strength corrugated cardboard box. Refer to Figure 1 , a high-strength corrugated cardboard box includes a box body 1. The box body 1 is a hollow cuboid with an open top. A box cover 11 for covering the open top of the box body 1 is rotatably provided on one side of the box body 1. A support assembly 2 for supporting the bottom of the box body 1 is provided on the box body 1. The support assembly 2 is used to support the bottom of the box body 1, avoid damage to the bottom of the box body 1 due to excessive weight, and at the same time, also avoid extrusion between two adjacent box bodies 1 and reduce damage to the box body 1.

[0036] The support assembly 2 includes a base 21 arranged in a horizontal direction. The cross-sectional shape of the base 21 is rectangular. A plurality of support columns 22 for supporting the box body 1 and a plurality of moving columns 23 for supporting the box body 1 are provided on the base 21. In this embodiment, the number of support columns 22 and the number of moving columns 23 are both two. A plurality of sliding grooves 211 are provided on the base 21. In this embodiment, the number of sliding grooves 211 is two. The shape of the support column 22 is L-shaped. The support column 22 is arranged in a vertical direction and the support columns 22 are parallel to each other. The bottom of the support column 22 is fixedly connected to the top of the base 21 by welding. The shape of the moving column 23 is the same as that of the support column 22. The moving column 23 is embedded in the sliding groove 211 and is slidably connected to the sliding groove 211. The moving column 23 and the support column 22 are located on both sides of the base 21 respectively. A clamping member 24 for clamping the box body 1 is provided on the base 21.

[0037] The clamping member 24 includes two fixing plates 241 arranged in a vertical direction. The fixing plates 241 are located on the side of the moving column 23 away from the support column 22. The bottom of the fixing plate 241 and the top of the base 21 are both fixedly connected by welding. A clamping spring 242 is provided between the fixing plate 241 and the moving column 23. One end of the clamping spring 242 is fixedly connected to the moving column 23 by welding, and the other end of the clamping spring 242 is fixedly connected to the fixing plate 241 by welding. The base 21 is used to support the box body 1. During use, move the moving column 23, and the moving column 23 presses the clamping spring 242 to make the clamping spring 242 in a compressed state. Then, place the box body 1 between the support columns 22 and release the moving column 23. Since the clamping spring 242 is in a compressed state and generates elastic force, the elastic force acts on the moving column 23, thereby squeezing the box body 1 to prevent the box body 1 from moving.

[0038] Refer to Figure 2, a high-strength corrugated cardboard box further includes an adjusting component 3 for increasing the heights of the supporting columns 22 and the moving columns 23, so that the supporting component 2 can support boxes of different heights. The adjusting component 3 includes an adjusting plate 31 and a sliding member 32. The number of the adjusting plates 31 is the same as the sum of the numbers of the supporting columns 22 and the moving columns 23. The shape of the adjusting plate 31 is the same as that of the supporting column 22. The adjusting plates 31 are respectively located on the sides of the supporting columns 22 or the moving columns 23 away from the base 21; the sliding member 32 is arranged between the supporting columns 22 and the moving columns 23 and is slidably connected to both the supporting columns 22 and the moving columns 23. The sliding member 32 includes a supporting plate 321 and a connecting plate 322 which is arranged in the supporting plate 321 and is slidably connected to the supporting plate 321. Both sides of the supporting plate 321 are slidably connected to the supporting columns 22, and both sides of the connecting plate 322 are slidably connected to the moving columns 23.

[0039] Referring to Figure 3 and Figure 4 , moving cavities 25 are formed in both the supporting columns 22 and the moving columns 23, and connecting rods 33 are arranged on both the supporting columns 22 and the moving columns 23. Therefore, in this embodiment, the number of the connecting rods 33 is four. The connecting rods 33 are arranged in the vertical direction, and the cross-sectional shape of the connecting rods 33 is circular. The connecting rods 33 are arranged in the moving cavities 25 and are slidably connected to the supporting columns 22 or the moving columns 23. The tops of the connecting rods 33 are fixedly connected to the bottoms of the adjusting plates 31 by welding. A plurality of telescopic members 34 are arranged between the sliding member 32 and the base 21. In this embodiment, the number of the telescopic members 34 is four. The telescopic members 34 include fixed tubes 341 arranged in the vertical direction and sliding rods 342 arranged in the vertical direction. The sliding rods 342 are arranged in the fixed tubes 341 and are slidably connected to the fixed tubes 341. The sliding rods 342 are hermetically connected to the fixed tubes 341. The bottoms of two of the fixed tubes 341 are fixedly connected to the base 21 by welding, and the other two fixed tubes 341 are fixedly connected to the moving columns 23 by welding. The tops of the sliding rods 342 are fixedly connected to the sliding member 32 by welding. Air pipes 35 are arranged on the fixed tubes 341, and the air pipes 35 are respectively communicated with the supporting columns 22 or the moving columns 23. One end of each air pipe 35 is communicated with and hermetically connected to the fixed tube 341, and the other end of the air pipe 35 is communicated with and hermetically connected to the moving cavity 25.

[0040] After the box is placed on the sliding member 32, due to the gravity of the box moving in the direction close to the ground, the sliding rod 342 moves along the direction of the fixed tube 341, and the gas in the fixed tube 341 flows into the supporting column 22 or the moving column 23 along the air pipe 35. The gas in the supporting column 22 and the moving column 23 increases, so as to push the connecting rod 33 to move in the direction away from the ground. The movement of the connecting rod 33 drives the adjusting plate 31 to move, thereby increasing the heights of the supporting column 22 and the moving column 23, so that the supporting component 2 can adapt to boxes of different heights.

[0041] A return spring 36 for returning the sliding rod 342 to its initial position is arranged inside the fixed tube 341. One end of the return spring 36 is fixedly connected to the bottom of the fixed tube 341 by welding, and the other end of the return spring 36 is fixedly connected to the bottom of the sliding rod 342 by welding. When the box is placed on the slider 32, the slider 32 presses the telescopic rod, causing the telescopic rod to move towards the end of the fixed tube 341 close to the bottom. The sliding rod 342 presses the return spring 36 to make the return spring 36 in a compressed state. The return spring 36 compresses to generate elastic force. When the box is removed from the slider 32, under the action of the return spring 36, the sliding rod 342 moves, causing the slider 32 to return to its initial position.

[0042] Scale lines 331 for measuring the weight of the box body 1 are arranged on the connecting rod 33. When the box body 1 is placed on the slider 32, the slider 32 moves towards the base 21. Under the action of the telescopic member 34, the connecting rod 33 slides away from the base 21. The length of the connecting rod 33 extending out is different for different weights of the box body 1, and the operator can estimate the weight of the box body 1 according to the scale.

[0043] Refer to Figure 3 and Figure 5 Refer to

[0044] Refer to Figure 2 and Figure 6, a fixing groove 213 is horizontally formed on the base 21. The number of the fixing grooves 213 is the same as that of the mounting grooves 212. The fixing grooves 213 are respectively communicated with the mounting grooves 212. A limiting groove 214 is formed on the side wall of the fixing groove 213. The cross-sectional shape of the limiting groove 214 is rectangular. Two relief grooves 411 are formed on the rotating shaft 41. The cross-sectional shape of the relief groove 411 is circular. The virtual included angle formed by the center line in the vertical direction of one relief groove 411 and the center line in the horizontal direction of the other relief groove 411 is ninety degrees. A limiting member 44 for restricting the rotation of the rotating shaft 41 is arranged on the base 21. The limiting member 44 includes a sliding plate 441 embedded in the limiting groove 214 and slidably connected with the limiting groove 214, and a fixing rod 442 passing through the fixing groove 213 and fixedly connected with the sliding plate 441. The cross-sectional shape of the sliding plate 441 is rectangular. The cross-sectional shape of the fixing rod 442 is T-shaped. The fixing rod 442 passes through the sliding plate 441. One end of the fixing rod 442 is embedded in the relief groove 411. A limiting spring 443 is arranged at one end of the sliding plate 441 away from the rotating shaft 41. The limiting spring 443 is located in the fixing groove 213. One end of the limiting spring 443 is fixedly connected with the sliding plate 441 by welding. The other end of the limiting spring 443 is fixedly connected with the side wall of the fixing groove 213 by welding.

[0045] The limiting member 44 is used to restrict the movement of the sliding plate 441. When the box body 1 needs to move, rotate the rotating wheel 43 to make the rotating wheel 43 contact with the ground. Then, restrict the movement of the rotating shaft 41 through the limiting member 44, so as to push the supporting assembly 2 to move. When the box body 1 does not need to move, rotate the rotating wheel 43 and place the moving assembly 4 in the mounting groove 212 to avoid damage to the moving assembly 4. When the position of the moving assembly 4 needs to be adjusted, pull the fixing rod 442 to the side away from the rotating shaft 41. The sliding plate 441 moves along with the movement of the fixing rod 442, so as to press the limiting spring 443 to make the limiting spring 443 in a compressed state. After adjusting the position of the moving assembly 4, release the fixing rod 442 to make the fixing rod 442 embedded in the relief groove 411, so as to fix the rotating shaft 41 and prevent the rotating shaft 41 from rotating.

[0046] The implementation principle of a high-strength corrugated cardboard box in an embodiment of this application is as follows: The operator takes out the moving component 4 from the installation groove 212. Then, the moving column 23 is moved, and the box body 1 is placed between the support column 22 and the moving column 23. After the box body 1 is placed on the sliding member 32, the moving column 23 is released. Under the action of the self-weight of the box body 1, the sliding member 32 moves, so that the adjusting plate 31 moves, forming a support for the side wall of the box body 1. At the same time, the operator can estimate the weight of the box body 1 according to the extended distance of the connecting rod 33. When the box body 1 is moved to the required position, the moving component 4 can be rotated so that the moving component 4 is located in the installation groove 212, avoiding damage to the moving component 4 and also avoiding damage to the adjacent box body 1. The support component 2 forms a support for the box body 1, avoiding extrusion between two adjacent box bodies 1 and reducing damage to the box body 1.

[0047] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
