Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a shockproof and cushioning packaging structure for foam products. Background Technology
[0002] With the rapid development of e-commerce and the continuous expansion of logistics and distribution networks, products need to travel longer distances and undergo more transit links to reach consumers. During this process, the risk of product damage increases, thus requiring more reliable shockproof and cushioning packaging. Large-scale industrial production has led to a significant increase in product output, which in turn increases the demand for packaging. Foam products are characterized by high production efficiency and relatively low cost, which can meet the packaging needs of large-scale production. At the same time, their lightweight nature can reduce transportation costs, further enhancing the competitiveness of foam products in industrial packaging.
[0003] During production, handling, and storage, foam products are subject to external impacts or compression. Excessive force can damage the foam's cell structure, affecting its cushioning, insulation, and thermal insulation properties. Without proper cushioning during transportation, foam products may deform or rupture due to collisions with hard objects or compression, damaging their originally uniform cell structure and reducing their effectiveness as a cushioning material. Without cushioning measures, foam products may experience internal cell rupture and deformation due to impacts, significantly reducing their original cushioning performance. When used to package fragile items, foam products cannot effectively absorb and disperse impact forces, increasing the risk of damage to the packaged items. The cell structure of foam plays a crucial role in its thermal insulation performance; damage to the cell structure alters the airflow path, affecting its thermal insulation properties. If foam boards are damaged locally during handling or installation without cushioning, the insulation effect of that area will be poor, impacting the overall energy efficiency of the building. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a shockproof and cushioning packaging structure for foam products. It aims to improve the problem in the prior art that if foam products cannot be cushioned, the internal cells will rupture and deform due to collision, which will greatly reduce their original good cushioning performance and affect the normal use of foam products.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a shockproof and cushioning packaging structure for foam products, including an outer shell, with hooks threadedly connected to the left and right sides of the inner wall of the outer shell, and a spring provided at the left end of hook one on the right side; a hollow box is provided inside the outer shell, with hooks threadedly connected to the left and right sides of the outer wall of the hollow box; a buffer plate two is fixedly connected to the bottom of the inner wall of the hollow box; a top cover is slidably connected to the top of the inner wall of the hollow box, with buffer plate one fixedly connected to the bottom of the top cover; lifting ropes are fixedly connected to the front and rear sides of the top of the inner wall of the outer shell, with hook three fixedly connected to the bottom of the lifting ropes; a sliding column is slidably connected to the top of the outer wall of the hollow box; and an auxiliary mechanism is provided at the bottom of the inner wall of the outer shell, the auxiliary mechanism being used to facilitate the removal of the hollow box.

[0008] As a further description of the above technical solution:
[0009] Trapezoidal plates are fixedly connected to the left and right sides of the outer wall of the shell, and weight-reduction holes are opened on the outer wall of the trapezoidal plates.
[0010] As a further description of the above technical solution:
[0011] The weight reduction hole is fixedly connected to the front and rear sides of the top, and a top plate is fixedly connected to the top of the support column.
[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the foam product is placed on the second buffer plate, and the top cover is pressed down so that it slides down the inner wall of the hollow box, so that the first buffer plate and the second buffer plate are tightly attached and the foam product is wrapped. Then, the sliding column is inserted and the third hook is hung in the groove on its outer wall so as to lift the hollow box. One end of the springs on both sides is hung on the second hook and the other end is hung on the first hook, so that the hollow box can be lifted steadily. This achieves the isolation between the hollow box and the outer shell. When the outer shell vibrates, since the hollow box and the outer shell are not in direct contact, it will not affect the hollow box.
[0022] 2. In this utility model, pulling the handle will cause the front cover to rotate, which in turn pulls the rope, causing the sliding block and trapezoidal block to slide outward and upward respectively, lifting the hollow box and making it detach from the sliding column. After being lowered smoothly, the hollow box can be removed by the second hook, realizing the safe removal of the hollow box, further ensuring the safety of the foam products and improving the usability of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 This utility model provides an embodiment of a shockproof and cushioning packaging structure for foam products, comprising an outer shell 1. Hooks 3 are threadedly connected to the left and right sides of the inner wall of the outer shell 1. A spring 4 is provided at the left end of the right hook 3. A hollow box 6 is disposed inside the outer shell 1. Hooks 5 are threadedly connected to the left and right sides of the outer wall of the hollow box 6. A buffer plate 12 is fixedly connected to the bottom of the inner wall of the hollow box 6. A top cover 10 is slidably connected to the top of the inner wall of the hollow box 6. The spring 4 provides additional elasticity and cushioning capacity to the entire device, absorbing some energy upon impact, thereby protecting the internal structure from damage. The buffer plate 12 is used to reduce the vibration and impact of the internal items during transportation. To ensure the integrity of the items, a buffer plate 11 is fixedly connected to the bottom of the top cover 10. A lifting rope 7 is fixedly connected to the top front and rear sides of the inner wall of the outer shell 1. A lifting hook 8 is fixedly connected to the bottom of the lifting rope 7. A sliding column 9 is slidably connected to the top of the outer wall of the hollow box 6. An auxiliary mechanism 2 is provided at the bottom of the inner wall of the outer shell 1. The auxiliary mechanism 2 is used to facilitate the removal of the hollow box 6. Multiple rotating blades 21 are fixedly connected to the front left end of the outer shell 1. The right rear end of the rotating blades 21 is fixedly connected to the front left end of the front cover 201. This enhances the overall structural stability of the outer shell 1, allowing the outer shell 1 to better disperse the force when subjected to external impacts, avoid local damage, and thus extend the service life of the entire equipment.
[0032] Specifically, hook 3 ensures the stability of the entire structure, allowing it to remain stable under gravity and external forces without easily deforming or breaking. Spring 4 provides additional elasticity and cushioning, absorbing some energy upon impact to protect the internal structure. Buffer plate 12 reduces vibration and impact on internal items during transport, ensuring their integrity. Buffer plate 11 further enhances the protective measures, effectively dispersing and absorbing vibrations for more comprehensive protection of internal items. Hook 8 not only facilitates the lifting of the hollow box 6 but also ensures stability and safety during handling, taking into account different angles. The lifting requirements of the hollow box 6 and the sliding column 9 make the opening and closing process of the top cover 10 smoother and easier to operate, greatly improving work efficiency. The auxiliary mechanism 2 makes the disassembly process of the hollow box 6 easy and convenient, reducing labor and time costs, and also reducing potential risks in the operation process. The rotating blade 21 is fixedly connected to the front cover 201, which enhances the overall structural stability of the outer shell 1, so that the outer shell 1 can better disperse the force when subjected to external impact, avoid local damage, and thus extend the service life of the entire equipment. The outer shell 1 takes into account durability and safety, ensuring that it can maintain good performance in various environments.
[0033] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 The auxiliary mechanism 2 includes a front cover 201, the outer wall of the front cover 201 is rotatably connected to the front side of the inner wall of the outer shell 1, a handle 202 is fixedly connected to the right front end of the front cover 201, a trapezoidal block 203 is slidably connected to the middle of the bottom surface of the inner wall of the outer shell 1, a pull rope 205 is fixedly connected to the left and right front ends of the trapezoidal block 203, a limit post 204 is slidably connected to the inner wall of the trapezoidal block 203, a sliding block 206 is slidably connected to the rear bottom of the inner wall of the outer shell 1, an anti-slip sleeve 19 is fixedly connected to the outer wall of the handle 202, and the front side of the pull rope 205 is fixedly connected to the rear side of the front cover 201.
[0034] Specifically, the outer shell 1 is rotatably connected to the front cover 201, ensuring structural flexibility and ease of operation. The handle 202 provides a comfortable grip point for the user, facilitating opening and closing. The trapezoidal block 203 takes functionality into consideration. The pull cord 205 is fixedly connected to the front cover 201, providing additional operational convenience for the user. The trapezoidal block 203 is slidably connected to the limit post 204, ensuring the stability and safety of the component during use. The sliding block 206 ensures smooth overall movement. The anti-slip sleeve 19 not only increases grip comfort but also enhances overall safety, further improving the user experience.
[0035] Please see the appendix Figure 1Appendix Figure 2 and attached Figure 3 Trapezoidal plates 14 are fixedly connected to the left and right sides of the outer wall of the outer shell 1. The outer wall of the trapezoidal plate 14 is provided with weight reduction holes 15. The trapezoidal plate 14 not only increases the structural stability of the outer shell 1, but also cleverly provides weight reduction holes 15 on its outer wall. The left and right sides of the outer wall of the sliding column 9 are threadedly connected with limit rings 13, and the two limit rings 13 are arranged symmetrically between them.
[0036] Specifically, the trapezoidal plate 14 not only increases the structural stability of the outer shell 1, but also cleverly opens weight-reducing holes 15 on its outer wall to reduce the overall weight without sacrificing strength. The limiting ring 13 functionally ensures the precise positioning of the sliding column 9 during use, preventing the risks that may be caused by excessive sliding.
[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The top and front sides of the weight reduction hole 15 are fixedly connected to the support column 16, and the top of the support column 16 is fixedly connected to the top plate 17. The support column 16 ensures the stability of the entire building or frame and provides a solid foundation for the structure above, so that the entire structure can safely bear various loads. The top of the top plate 17 is fixedly connected to the sign plate 18, and the bottom left and right sides of the top plate 17 are fixedly connected to the diagonal bar 20.
[0038] Specifically, the support column 16 ensures the stability of the entire building or frame, providing a solid foundation for the structure above, enabling the entire structure to safely bear various loads. The identification plate 18 records key information about the structure in detail, helping staff to quickly identify each part and ensuring the safety and functionality of the structure. The diagonal brace 20 effectively disperses stress and pressure in the structure, thereby improving the overall stability and wind resistance.
[0039] Working principle: Place the foam product on top of the second buffer plate 12, and then press the top cover 10. The top cover 10 will slide down along the inner wall of the hollow box 6, and make the first buffer plate 11 and the second buffer plate 12 fit tightly together, so that the foam product is completely wrapped inside the first buffer plate 11 and the second buffer plate 12. Then insert the sliding column 9 and hang the third hook 8 in the groove on the outer wall of the sliding column 9, so that the hollow box 6 is lifted. Then hang one end of the two springs 4 on the second hook 5 and the other end on the first hook 3, so that the hollow box 6 can be lifted steadily, achieving isolation between the hollow box 6 and the outer shell 1. When the outer shell 1 vibrates, since the hollow box 6 and the outer shell 1 are not in direct contact, it will not affect the hollow box 6.
[0040] When handle 202 is pulled, handle 202 will cause front cover 201 to rotate along the front side of outer shell 1. While rotating, front cover 201 will pull the pull rope 205 on the rear side, which will cause sliding block 206 to slide outward along the inner wall of outer shell 1 and trapezoidal block 203 to slide upward along the outer wall of limit post 204, finally lifting hollow box 6. Then hook 3 8 will no longer hook sliding post 9, and hollow box 6 can be lowered smoothly. Finally, contact with hook 2 5 on both sides can remove hollow box 6, realizing the safe removal of hollow box 6, further ensuring the safety of foam products and improving the usability of equipment.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
