Description

Technical Field

[0001] This utility model relates to the field of shock absorption and waterproofing technology, and in particular to a shock absorption and waterproofing foam box. Background Technology

[0002] Foam boxes are plastic boxes made from polystyrene resin through a foaming molding process. They are lightweight, low-cost, and have good thermal insulation properties, and are used in fresh food cold chain transportation, food preservation, and electronic product packaging.

[0003] Shock-absorbing and waterproof foam boxes achieve shock absorption and waterproofing functions through structural design and material combination. In terms of shock absorption, springs and dampers are set inside the box to absorb shock absorption components, or a multi-layered foam nesting structure is adopted. The deformation of the components absorbs the impact force, reducing the impact of vibration on the items inside the box. In terms of waterproofing, sealing strips are added to the seams of the box and waterproof grooves are set, combined with the airtight characteristics of the box itself, to prevent moisture from entering the box and keep the items inside dry.

[0004] However, the existing shock-absorbing structures have insufficiently secure connections between the shock-absorbing components and the foam box, leading to loosening and reduced shock absorption after prolonged use. Furthermore, the multi-layered nested foam structure can misalign under strong impacts, failing to provide sustained and effective shock absorption. Regarding waterproofing, the sealing strips age and lose elasticity after repeated opening and closing or prolonged use, and the accumulation of debris in the waterproof grooves can also affect waterproofing. Finally, existing shock-absorbing and waterproof foam boxes have simple structures and limited cushioning capabilities, making them unsuitable for long-term use and unable to cope with various bumpy environments.

[0035] The shock absorption mechanism 3 includes 3M adhesive 31.

[0045] Specifically, the top of the waterproof mechanism 4 of the box lid is provided with a box lid handle groove 6; a top handle reinforcing rib 7 is fixedly connected inside the box lid handle groove 6, and the top handle reinforcing rib 7 is fixedly connected to the inner wall of the box lid handle groove 6 to enhance the strength of the box lid handle groove 6; multiple anti-slip grooves 9 are provided on the inner side of the inner foam box 5; multiple item isolation rails 8 are slidably connected inside the multiple item anti-slip grooves 9, and the position of the item isolation rails 8 can be freely adjusted due to the sliding connection structure between the item isolation rails 8 and the item anti-slip grooves 9; multiple lower magnetic buckles 10 are fixedly connected to the top of the inner foam box 5, and multiple upper magnetic buckles 11 are correspondingly fixedly connected to the top of the inner side of the waterproof mechanism 4, and the top of the multiple lower magnetic buckles 10 and the bottom of the multiple upper magnetic buckles 11 can be magnetically connected;

[0046] Multiple upper interface grooves 12 are provided at the four corners of the top of the box lid waterproof mechanism 4. The position, shape and size of the upper interface grooves 12 match the bottom pillars 13 of the foam box. Multiple bottom pillars 13 of the foam box are fixedly connected at the four corners of the bottom of the outer shell foam 1. The bottom of the multiple bottom pillars 13 of the foam box corresponds to the multiple upper interface grooves 12, forming a snap-fit ​​connection structure. Side handle grooves 14 are provided on the left and right sides of the outer shell foam 1. The side handle grooves 14 are convenient for users to hold. Side handle reinforcing ribs 15 are fixedly connected inside the two side handle grooves 14. The side handle reinforcing ribs 15 are connected to the inner wall of the side handle grooves 14 by a fixed connection method, which improves the load-bearing capacity of the side handle grooves 14.

[0047] The damping rod 34 is composed of multiple outer damping plates 341 and inner damping plates 342; the rear of the multiple outer damping plates 341 is fixedly connected to the outer side of multiple inner connecting plates 32; the inner side of each of the multiple outer connecting plates 32 is fixedly connected to an inner damping plate 342, and the outer side of the multiple inner damping plates 342 and the interior of the multiple outer damping plates 341 form a sliding connection structure, and the inner damping plates 342 can slide in a specific direction inside the outer damping plates 341;

[0048] Through the structural design and mutual cooperation of the above components, the system provides stable waterproofing, convenient operation, effective shock absorption, and reasonable item separation in scenarios of item storage, handling, and transportation.

[0049] Working principle: The outer foam 1 serves as the outer protective layer of the overall structure, with an internal storage compartment 2 for storing items. An inner foam box 5 is located inside the outer foam 1, providing further protection for the items. A shock-absorbing mechanism 3 is located between the outer foam 1 and the inner foam box 5. Multiple 3M adhesive strips 31 are fixedly connected to the inner side of the storage compartment 2 and the outer side of the inner foam box 5, establishing a basic connection between the two. Connecting pieces 32 are fixedly connected to adjacent sides of the 3M adhesive strips 31, increasing the connection area and strength. Support columns 33 are fixedly connected to the outer side of the inner connecting pieces 32, providing support for the inner foam box 5. A retaining device is installed between the inner and outer connecting pieces 32. The inner foam box 5 is equipped with a damping rod 34, and a shock-absorbing spring 35 is fixedly connected between the two connecting plates 32. When the foam box is subjected to external impact, the inner foam box 5 drives the connecting plates 32 to move, causing the shock-absorbing spring 35 to undergo compression or tension deformation. The outer damping plate 341 of the damping rod 34 slides relative to the inner damping plate 342, consuming the impact energy. The elastic deformation of the shock-absorbing spring 35 and the damping effect of the damping rod 34 work together to effectively buffer the external impact force, prevent the items inside the inner foam box 5 from being damaged by vibration, realize shock absorption protection for the items inside the box in the bumpy transportation scenario, reduce the risk of damage to the items caused by vibration, and improve the safety of the items during transportation and storage.

[0050] The waterproof mechanism 4 uses a foam box lid 41 as its core component. The bottom of the foam box lid 41 is connected to the top of the outer foam 1 to achieve the opening and closing action. A waterproof upper opening 42 is opened at the bottom of the foam box lid 41, and a corresponding waterproof lower opening 43 is opened at the top of the outer foam 1. When the foam box lid 41 is closed, the waterproof upper opening 42 and the waterproof lower opening 43 are engaged with each other, and their contact surfaces are tightly connected. The tight engagement of the waterproof upper opening 42 and the waterproof lower opening 43 ensures that moisture cannot enter the foam box. This structural design effectively blocks external moisture, ensuring that the inside of the foam box remains dry in humid environments and rainy weather, preventing the internal items from getting damp and damaged, and achieving waterproof protection for the items inside the box, meeting the storage and transportation requirements of items that require waterproofing.

[0051] Multiple anti-slip grooves 9 are provided on the inner side of the inner foam box 5, and item isolation rails 8 are slidably connected in the anti-slip grooves 9. Users can adjust the position of the item isolation rails 8 along the anti-slip grooves 9 according to the size and shape of the items, which can divide the interior of the inner foam box 5 into different areas. This structure realizes flexible separation and fixation of items in the box, avoids items from colliding and shifting with each other in the box, meets the needs of different item classification and storage, and further protects the integrity of items during transportation and storage.

[0052] The top of the inner foam box 5 is fixedly connected to the lower magnetic buckle 10, and the top of the inner side of the waterproof mechanism 4 of the box lid is fixedly connected to the upper magnetic buckle 11. When the foam box lid 41 is closed, the lower magnetic buckle 10 and the upper magnetic buckle 11 are connected to each other by magnetic attraction. Compared with the traditional buckle connection method, this magnetic connection method ensures that the box lid and the box body are firmly connected, while making it easier to open and close the operation, simplifying the use process of the foam box and improving the convenience of operation.

[0053] The top of the waterproof lid mechanism 4 has a lid handle groove 6, with a top handle reinforcing rib 7 fixedly connected inside. The left and right sides of the outer foam 1 have side handle grooves 14, with side handle reinforcing ribs 15 fixedly connected inside. The lid handle groove 6 and the side handle grooves 14 provide gripping points for users, while the top handle reinforcing ribs 7 and the side handle reinforcing ribs 15 enhance the structural strength of the grooves. When handling the foam box, the user grips the handle grooves, and the reinforcing ribs ensure that the grooves will not easily deform or be damaged, improving the stability and safety of the handling process and facilitating the handling of the foam box.

[0054] The top corner of the waterproof mechanism 4 of the box lid is provided with an upper interface groove 12, and the bottom corner of the outer shell foam 1 is fixedly connected to the bottom column 13 of the foam box; when multiple foam boxes are stacked, the bottom column 13 of the foam box can be locked in the upper interface groove 12; this structure makes the foam boxes stable when stacked, improves space utilization efficiency, and facilitates the storage and transportation management of foam boxes.

[0055] Through the design and coordination of various components, including the outer foam 1, the item storage compartment 2, the inner foam box 5, the shock absorption mechanism 3, and the waterproof lid mechanism 4, comprehensive protection is provided for the items inside the box in various transportation and storage scenarios, including shock absorption, waterproofing, flexible partitioning, convenient operation, and stable stacking.

[0056] 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.
