Technical Field
[0001] This utility model relates to the field of cardboard box technology, specifically to an outer packaging cardboard box with a wear-resistant inner lining. Background Technology
[0002] Outer packaging cartons serve as a carrier for logistics transportation and product protection, enabling the protection of products. Common cartons are made of three layers of corrugated cardboard, providing protection, cost-effectiveness, efficiency, environmental friendliness, and sustainability.
[0003] According to Chinese Patent Publication No. CN218807212U, "A Lining for Outer Packaging Cardboard Boxes," the main features include a box with four fixedly connected cover plates on the top four sides, forming the box lid. The bottom of the box has a base shell, which is fixedly connected to the box body. Reinforcing ribs are provided at the four corners of the base shell, and these ribs are also fixedly connected to the base shell. The base shell is made from a single piece of cardboard and has no seams at the bottom. The base shell enhances the load-bearing capacity of the box bottom and increases its wear resistance and moisture resistance. The reinforcing ribs increase the compressive strength of the base shell and reduce box deformation. A groove is provided on one side of the box, penetrating the box body. A handle is provided on the groove, fixedly connected to the box body, and fits snugly around the inside and outside of the groove. The handle is made of plastic, facilitating manual handling of the box.
[0004] Common outer packaging for fragile items such as glass and precision instruments requires cushioning with foam, bubble wrap, and newspaper. Some products have irregular shapes, and the contact effect between the inner lining and the product is not good when adding an inner lining. However, during transportation, the carton may be subjected to vibration, shaking, or tilting, causing relative movement between the product and the inner lining, and between the inner lining and the inner wall of the carton, resulting in wear and tear on the inner lining material. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an outer packaging carton with a wear-resistant inner lining, thereby reducing relative movement between the inner lining and the carton, and between the product and the inner lining, when the inner lining is inside the carton, thus reducing wear on the inner lining material.
[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: an outer packaging carton with a wear-resistant inner lining, including a carton body and a sealing plate. The upper and lower sides of the carton body are bonded to the sealing plate. The upper and lower sides of the inner carton body are in contact with a cover plate. The upper and lower sides of the inner carton body are in contact with a first pad plate. The inner carton body is provided with a second pad plate on both sides of the first pad plate. The first pad plate has protrusions evenly fixedly connected to both sides. The protrusions are inserted into recesses. The recesses are located on the second pad plate. The first pad plate and the second pad plate are evenly fixedly connected to the upper and lower sides with locking blocks. The locking blocks are inserted into locking grooves. The locking grooves are located on the opposite side of the two cover plates. The first pad plate and the second pad plate have limit holes evenly penetrating the upper and lower sides. The corresponding two limit holes are inserted with protrusions. The two protrusions are fixedly connected with pressure plates, and the pressure plates are staggered.
[0007] As a preferred technical solution of this utility model, a limiting groove is provided on one side of each of the two cover plates. The limiting groove is circular. Alternatively, the limiting groove can be circular, rectangular, rhomboid, or other structures to adapt to different bottom and top structures of materials.
[0008] As a preferred technical solution of this utility model, a circular plate is inserted into the limiting groove on the upper side, and an extrusion plate is fixedly connected to the side of the circular plate near the pressure plate. Alternatively, the circular plate can be a square plate, a rectangular plate, a diamond plate, or other structures, which can provide further limiting for materials with holes at the top.
[0009] As a preferred technical solution of this utility model, the number of openings of the limiting hole is odd, and the limiting hole has a square structure. Alternatively, the limiting hole can be a strip structure.
[0010] As a preferred technical solution of this utility model, an insert is inserted into the limiting hole located at the center of the pressure plate. The insert corresponds to the pressure plate. Alternatively, the insert can be in the shape of a rectangular column, a cylinder, or other structures.
[0011] As a preferred technical solution of this utility model, a gasket is fixedly connected to the side of the insert near the pressure plate. The gasket is in contact with the pressure plate. By setting the gasket, the contact surface between the first pad, the second pad and the insert can be increased.
[0012] This utility model has the following advantages: by setting a first pad, a second pad, and a cover plate inside the box, a closed structure can be formed to protect the material. Then, by inserting a pressure plate, insert strip, and gasket into the limiting hole, a limiting structure for the upper and lower sides of the material can be formed, which can reduce the relative movement between the product and the inner lining, and between the inner lining and the inner wall of the carton, and reduce the wear of the inner lining.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Please refer to the following: Figure 1-3 The illustrated outer packaging carton with a wear-resistant inner lining includes a carton body 1 and a sealing plate 2. The sealing plate 2 is glued to both the top and bottom sides of the carton body 1. The sealing plates 2 on both sides of the carton body 1 can rotate to close the top and bottom of the carton body 1, and then form a box-like structure through adhesive, facilitating stacking. A cover plate 3 contacts both the top and bottom sides of the inside of the carton body 1, and a first pad plate 4 contacts both sides of the inside of the carton body 1. A second pad plate 5 is provided on both sides of the first pad plate 4 inside the carton body 1. The protrusions 7 and locking blocks 6 on the first pad plate 4 and the second pad plate 5 increase the tightness of the connection between the first pad plate 4, the second pad plate 5, and the cover plate 3. The first pad 4 has protrusions 7 evenly fixedly connected on both sides, and the protrusions 7 are inserted into the recesses. The recesses are located on the second pad 5. The first pad 4 and the second pad 5 have locking blocks 6 evenly fixedly connected on their upper and lower sides. The locking blocks 6 are inserted into the locking slots, which are located on the opposite side of the two cover plates 3. The first pad 4 and the second pad 5 have limiting holes 8 evenly connected on their upper and lower sides. The corresponding two limiting holes 8 have protrusions inserted into them. The two protrusions are fixedly connected to a pressure plate 10, and the pressure plates 10 are staggered. The protrusions are inserted into the pressure plates 10 in such a way that the corresponding limiting holes 8 on both sides of the central limiting hole 8 are used to limit the pressure plates 10.
[0020] Among them, a limiting groove 9 is opened on one side of each of the two cover plates 3. The limiting groove 9 has a circular structure. By setting the limiting groove 9 between the two cover plates 3, the material can be further limited, thereby improving the stability of the material movement.
[0021] A circular plate is inserted into the upper limiting groove 9, and an extrusion plate 13 is fixedly connected to the side of the circular plate near the pressure plate 10. By setting the extrusion plate 13, the material with holes at the top can be further limited.
[0022] Among them, the number of openings of the limiting hole 8 is odd, and the limiting hole 8 has a square structure. By setting an odd number of limiting holes 8, the insertion strip 12 at the center can correspond to the center point of the pressure plate 10.
[0023] Among them, a strip 12 is inserted into the limiting hole 8 located at the center of the pressure plate 10. The strip 12 corresponds to the pressure plate 10. By setting the strip 12, the strip 12 can be bent under force, which can increase the stability of the arc-shaped structure of the pressure plate 10.
[0024] Among them, a gasket 11 is fixedly connected to the side of the insert 12 near the pressure plate 10. The gasket 11 is in contact with the pressure plate 10. By setting the gasket 11, the contact surface between the insert 12 and the pressure plate 10 can be increased, thereby increasing the effect of stabilizing and limiting the material.
[0025] Among them, the first pad 4, the second pad 5, the cover plate 3, the pressure plate 10, the gasket 11, the insert strip 12 and the extrusion plate 13 are all made of foam cotton structure, and the box body 1 and the sealing plate 2 are made of corrugated cardboard.
[0026] Working principle: Select a cover plate 3 with a suitable limiting groove 9 according to the structure of the material. Then, connect the bottom cover plate 3 to two first pads 4 and second pads 5. The adjacent first pads 4 and second pads 5 are connected by protrusions 7 and recesses. Then, the slot of the bottom cover plate 3 is connected to the locking block 6 of the first pads 4 and second pads 5. At this time, the assembled structure is placed into the fitted box 1. Then, the pressure plate 10 is bent into a certain arc and the protrusions on both sides of the pressure plate 10 are inserted into the corresponding limiting holes 8 on both sides. At the same time, the four pressure plates 10 can be arranged in an alternating manner to make the limiting effect better. Then, insert the strip 12 so that the gasket 11 contacts the side of the pressure plate 10 away from the material, providing stable limiting of the material, reducing the shaking of the material, reducing the relative movement between the product and the inner lining, and between the inner lining and the inner wall of the carton, and reducing the wear of the inner lining.
[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
[0028] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
