Description

Technical Field

[0001] This utility model relates to the field of thermal insulation box technology, and in particular to a composite waterproof thermal insulation box. Background Technology

[0002] An insulated box is a container that maintains its internal temperature and is widely used in food transportation, medical equipment protection, and other applications requiring temperature control. The core of an insulated box lies in its insulation material, which effectively insulates against external temperatures and maintains a stable internal temperature. Common insulation materials include polystyrene (EPS), polyurethane (PU), and expanded polypropylene (EPP). Among these materials, EPP is increasingly favored due to its excellent environmental performance and recyclability. EPP (Expanded Polypropylene) is a polymer material formed by mixing polypropylene resin with a foaming agent through a special process and then heating it to foam. The closed-cell structure of EPP gives it excellent insulation properties and also effectively absorbs impact, protecting the contents from damage.

[0003] Chinese utility model patent application publication CN212501966U discloses a foam insulated box and insulated box. Although the foam insulated box and insulated box solve the problem of water leakage, when the waterproof membrane layer is placed on the inner wall of the box, the smoothness of the waterproof membrane layer causes the items loaded inside the box to slip and / or shake due to inertia during transportation. There may even be collisions between the items and the box, causing fragile items or stacked takeout boxes to collide, resulting in poor stability of the items stored in the insulated box. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing insulated boxes where the waterproof membrane layer is placed on the inner wall of the box. Due to the smooth nature of the waterproof membrane layer, the items inside the box may slip and / or shake due to inertia during transportation, or even collide with the box. This can cause fragile items or stacked takeout boxes to collide, resulting in poor stability of the items stored in the insulated box. Therefore, a composite waterproof insulated box is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite waterproof and insulated box includes a box body and a box cover assembled on the box body for sealing, characterized in that the box body is provided with a waterproof component for preventing water leakage.

[0007] Furthermore, the waterproof component includes an inner liner and a retaining slot formed on the outside of the inner liner.

[0008] Specifically, the waterproof component is connected to the housing by glue and / or clips.

[0009] Furthermore, the opening of the inner liner extends outward with an integrally formed fitting edge, the end of which contacts the inner wall of the box.

[0010] Furthermore, the box body includes an outer shell, and a first reinforcing part and a second reinforcing part are integrally formed inside the outer shell. The second reinforcing part is distributed in at least two sets. A lifting part is provided on the outside of the outer shell, and the lifting part is a lifting clip and / or a handle.

[0011] Furthermore, a locking position is formed between the two sets of second reinforcing parts, and the locking position one and the locking position two are in a concave-convex fit.

[0012] Furthermore, it also includes a temperature-regulating component disposed on the waterproof component, the temperature-regulating component comprising a thin plate and a connector.

[0013] Furthermore, a connecting plate is installed between the plug and the thin plate, and the connecting plate and the thin plate are movably connected by a hinge.

[0014] Furthermore, the connector and the connecting plate are connected by threads. The connector includes a plug post and a base plate, and the connectors are distributed in an inverted "T" shape.

[0015] Furthermore, the length of the connector is the same as the length of the thin plate, and a locking position is formed between the temperature control component and the inner liner.

[0016] Furthermore, the plug-in pin on the connector is fitted with a water-absorbing element, and there are at least two sets of water-absorbing elements. The water-absorbing element and the inner liner form a storage space where an insulation element is placed.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the waterproof component provides a leak-proof function for the insulated box. The second locking position of the waterproof component and the second locking position of the box body are interlocked, which makes the connection between the waterproof component and the insulated box good. The groove formed by the interlocking of the two parts can be used to place the insulated component and / or the partition. Through this structural design, the waterproof component can be divided into two storage spaces, which can ensure the stability of storing a small number of items. The storage space formed by the constant temperature component and the inner liner is used to place the insulated component, which improves the insulation effect of the insulated box. The water-absorbing component absorbs the liquid released by the insulated component. This structural design helps to improve the stability of items stored in the insulated box and has high practicality.

[0019] 2. In this utility model, the movable structure between the connecting plate and the thin plate allows the connecting plate to be rotated to the side of the thin plate when the plug is not used, thus completing the storage of the connecting plate. This is suitable for items that do not require insulation and can maximize the use of the internal storage space of the insulated box. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-4 A composite waterproof and insulated box includes a box body 1 and a box cover 2 assembled on the box body 1 for sealing. The box body 1 is provided with a waterproof component 3 for preventing water leakage.

[0028] The waterproof component 3 includes an inner liner 301 and a locking slot 303 formed on the outside of the inner liner 301. Furthermore, the waterproof component 3 is connected to the box body 1 by glue and / or snap fasteners.

[0029] By adopting the above technical solution, the waterproof component 3 is installed inside the insulated box, giving the insulated box a leak-proof function. The waterproof component 3 is connected to the box body 1 by glue and / or buckles, making the connection between the waterproof component 3 and the box body 1 stable.

[0030] The inner liner 301 has an integrally formed edge 302 extending outward from the opening, and the end of the edge 302 contacts the inner wall of the box 1.

[0031] Specifically, the inner liner 301, through the fitting edge 302, ensures that the opening of the waterproof component 3 is tightly fitted to the opening of the box body 1, preventing leakage from seeping into the space between the waterproof component 3 and the insulation box, thus avoiding water seepage. At the same time, by connecting the fitting edge 302 to the first reinforcing part 102 and the second reinforcing part 103 with glue and / or clips, the connection stability between the waterproof component 3 and the insulation box can be improved.

[0032] The box body 1 includes an outer shell 101. The outer shell 101 has a first reinforcing part 102 and a second reinforcing part 103 integrally formed inside. The second reinforcing part 103 is distributed in at least two sets. The outer shell 101 is provided with a lifting part 4, which is a lifting slot and / or a handle.

[0033] Specifically, the first reinforcing part 102 and the second reinforcing part 103 can enhance the strength of the side wall of the insulated box. The lifting part 4 facilitates the loading and unloading of the insulated box after the items are loaded.

[0034] A locking position 104 is formed between the two sets of second reinforcing parts 103, and the locking position 104 and the locking position 2 303 are in a concave-convex fit.

[0035] Specifically, the inner liner 301 completes the snap-fit ​​operation through the interlocking of the second snap-fit ​​303 and the first snap-fit ​​104, resulting in a good connection between the waterproof component 3 and the insulation box. When gluing, the adhesive between the waterproof component 3 and the insulation box cures better. When snap-fitting, the interlocking of the second snap-fit ​​as a reference allows other snap-fit ​​holes to align smoothly, improving the assembly efficiency of the waterproof component 3 and the insulation box. Furthermore, the groove formed by the interlocking of the second snap-fit ​​can be used to place the boxed insulation component 7 and / or the partition. Through this structural design, the waterproof component 3 can form two storage spaces for storing items, ensuring stability when storing a small number of items.

[0036] It also includes a temperature control component 5 disposed on the waterproof component 3, the temperature control component 5 including a thin plate 501 and a connector 505.

[0037] By adopting the above technical solution, the thin plate 501 is located on the inner wall of the insulated box and is installed vertically. The material of the thin plate 501 can be plastic, alloy or other materials. This utility model does not impose specific restrictions on the material of the thin plate 501. By installing the thin plate 501 vertically in the box 1, the strength of the side walls of the two long sides of the box 1 is strengthened. It is suitable for stacking insulated boxes that carry a lot of heavy items or for occasions where extra protection is required during transportation.

[0038] A connecting plate 503 is installed between the plug-in 505 and the thin plate 501, and the connecting plate 503 and the thin plate 501 are movably connected by a hinge 502.

[0039] Specifically, through the movable connection between the connecting plate 503 and the thin plate 501, the connecting plate 503 can be rotated to the side of the thin plate 501 to complete the storage of the connecting plate 503. This is suitable for storing items that do not require additional insulation components 7 and can maximize the use of the internal storage space of the insulated box.

[0040] The connector 505 and the connecting plate 503 are connected by threads. The connector 505 includes a plug post and a base plate 504, and the connector 505 is distributed in an inverted "T" shape.

[0041] Furthermore, the threaded connection between the connector 505 and the connecting plate 503 facilitates the replacement of the connector 505.

[0042] The length of the connector 505 is the same as the length of the thin plate 501, and a locking three-way junction is formed between the thermostatic component 5 and the inner liner 301.

[0043] Specifically, by setting the locking position 36, the box-shaped insulation component 7 is made to fit with the locking position 36 in a concave-convex manner, so that the insulation component 7 is placed more stably.

[0044] The plug-in pin on the connector 505 is fitted with a water-absorbing component 506. There are at least two sets of water-absorbing components 506. The water-absorbing component 506 and the inner liner 301 form a storage space where an insulation component 7 is placed.

[0045] Furthermore, the insulation component 7 can be made of materials used for cooling and / or heating, such as ice blocks, ice packs, and heating bags (this utility model does not limit the structure and principle of the insulation component 7; it can be the same as or implemented using existing technology, which will not be elaborated here; this product does not specifically limit the specifications and types of the insulation component 7). The water-absorbing component 506 is cylindrical and / or square. When it is cylindrical, the two sets of cylindrical water-absorbing components 506 are connected by a breathable cloth, so that while providing insulation for the items inside the insulated box, it can effectively prevent the insulation component 7 from collapsing onto the items stored inside the insulated box due to the inertia of the box body 1. It has high practicality. Through the water absorption characteristics of the water-absorbing component 506, the water vapor released from the outside of the insulation component 7 can be absorbed, which can prevent liquid from flowing into the items and increase the lubrication between it and the waterproof component 3. This structural design is conducive to improving the stability of the items stored in the insulated box and has high practicality.

[0046] Working principle: During the assembly of the waterproof component 3 and the box body 1, the inner liner 301 is confined within the box body 1 by engaging the locking positions 303 and 104 on the waterproof component 3. This ensures a good connection between the waterproof component 3 and the insulation box, resulting in better adhesive curing during bonding. When using snap-fit ​​connections, the interlocking mechanism allows other locking holes to align smoothly, improving assembly efficiency. Furthermore, the groove formed by the interlocking mechanism can accommodate the boxed insulation component 7 and / or partitions. This structural design creates two storage spaces for the waterproof component 3, ensuring stability when storing small quantities of items. Then, the temperature-regulating component 5 on the waterproof component 3 and the locking position 6 formed by the locking position 3 on the side wall of the inner liner 301 further facilitate the connection of the insulation component 7. Items such as ice blocks, ice packs, and heating bags enhance the insulation effect of the insulated box. Furthermore, the connector 505 facilitates the installation of the absorbent component 506 within the waterproof component 3, absorbing liquid released from the insulation component 7 placed in the slot 3 6, preventing liquid from flowing into the storage area and making the connection between the item and the inner liner 301 more slippery, thus reducing the stability of the item stored in the insulated box. The thin plate 501, vertically installed inside the box body 1, strengthens the side walls of the two long sides of the box body 1, making it suitable for stacking insulated boxes carrying multiple heavy items or for situations requiring extra protection during transportation. The connecting plate 503, movably connected to the thin plate 501, allows the connecting plate 503 to be rotated to the side of the thin plate 501, completing the storage of the connecting plate 503. This is suitable for items that do not require insulation with the insulation component 7, maximizing the use of the internal storage space of the insulated box.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
