Description

Technical Field

[0001] This utility model relates to the field of thermal insulation foam boxes, specifically a thermal insulation foam box. Background Technology

[0002] Foam boxes are box-shaped packaging containers made of foamed plastic. Their interiors contain numerous tiny pores, which give them unique properties. Below is a detailed introduction to foam boxes. Foam boxes are primarily made of foamed plastic, especially expandable polystyrene foam. This is a lightweight material made from polystyrene resin as a base material, with the addition of foaming agents and other auxiliary materials, and then expanded by heating. Foam boxes are typically box-shaped, with both external and internal dimensions. Specific dimensions vary depending on the model and application. As a lightweight packaging material with good thermal insulation properties, foam boxes have a broad market prospect in cold chain logistics, food transportation, and other fields. Foam boxes are a packaging material with unique properties and wide applications. Insulated foam boxes generally refer to boxes made of specific materials with good thermal insulation properties. Insulated foam boxes are an important packaging product with wide applications in many fields. Their excellent thermal insulation performance, lightweight and durable characteristics, and environmentally friendly and sustainable development trends ensure that they will maintain an important position in the future market.

[0003] According to Chinese Patent Publication No. CN211810992U, a transportable insulated foam box includes a box body and a lid. The box body and lid are movably connected. A mounting block is glued to the lower surface of the box body. The lower surface of the mounting block has an opening. Two first threaded rods are rotatably connected to the inner left side wall of the mounting block via bearings. In use, when the box needs to be moved, rotating the rotating rod causes the first material rod and the second threaded rod to rotate synchronously. This causes the threaded sleeve to move the rack along a groove, which in turn drives the gear to rotate. The gear then drives the mounting plate and wheels to rotate, bringing the wheels into contact with the opposite side, facilitating movement. When movement is not needed or the user picks up the box, rotating the rotating rod in the opposite direction similarly rotates the wheels into the interior of the mounting block, improving the aesthetics of the device and facilitating transport.

[0004] In the above solution, an installation block is glued to the lower surface of the box. The lower surface of the installation block has an opening. The inner left side wall of the installation block is rotatably connected to two first threaded rods through bearings. This results in the following disadvantages: In the use of existing foam boxes, due to the large gap between the foam box and the top cover, the sealing performance of the foam box is low, resulting in poor insulation performance. Moreover, the top cover of the existing foam box is placed directly on without being fixed, which makes it easy to lose the top cover during transportation, reducing the practicality of the foam box. The existing foam box only has one layer when in use, resulting in poor insulation effect. In addition, the foam box is easily damaged when subjected to external impact. Since the volume of the items stored inside the insulated foam box cannot be the same as the size of the box space, the items shake and collide back and forth inside the insulated foam box during transportation, causing damage to the items. Utility Model Content

[0005] The purpose of this invention is to provide an insulated foam box to solve the problem that the existing foam boxes have poor insulation performance due to the large gap between the foam box and the top cover, resulting in low sealing performance.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a heat-insulating foam box, including an outer box body, wherein the outer box body is provided with a heat-insulating component that can enhance the heat insulation of the foam box, and an inner box body is provided inside the outer box body, wherein the inner box body is provided with a buffer component that can buffer the external impact of the foam box.

[0007] Preferably, the insulation component includes a fixing handle, which is fixedly connected to the outer casing. The outer casing has a fixing groove, and a sealing sleeve is fixedly connected to the top surface of the outer casing. An insulation box cover is provided on the top surface of the sealing sleeve, and a square plate is fixedly connected to the bottom surface of the insulation box cover. A strip groove is provided on the insulation box cover.

[0008] Preferably, the inner box has a groove, the inner wall of the groove is fixedly connected to a heat insulation layer, the inner wall of the groove is fixedly connected to a heat preservation layer, and the inner wall of the groove is fixedly connected to a reinforcing layer.

[0009] Preferably, the cushioning assembly includes sponge blocks, which are fixedly connected to the outer casing. One side of a plurality of sponge blocks is fixedly connected to the inner casing. A plurality of pearl cotton is fixedly connected inside the outer casing, and one side of the plurality of pearl cotton is fixedly connected to the inner casing.

[0010] Preferably, a plurality of first shock-absorbing airbags are fixedly connected inside the inner box, a partition is fixedly connected to the top surface of the inner box, and second shock-absorbing airbags are fixedly connected to the left and right sides of the partition.

[0011] Preferably, a handle is fixedly connected to the top surface of the insulated box lid.

[0012] Preferably, the bottom surface of the outer casing is coated with a waterproof liquid.

[0013] Preferably, the outer wall of the outer casing is coated with polyurethane.

[0014] Preferably, the outer wall of the inner casing is coated with acrylic acid.

[0015] Preferably, the bottom surface of the outer casing is provided with anti-slip texture.

[0016] Compared with existing technologies, the thermal insulation foam box that adopts the above technical solution has the following beneficial effects:

[0017] 1. During use, place the items into the inner box, then place the insulated box lid onto the outer box. The square plate fixed to the bottom of the lid is then inserted into the fixing groove. The lid is then pressed down to fit snugly against the sealing sleeve, enhancing the insulation effect of the foam box. Finally, use ropes along the strip grooves on the lid to secure it to the fixing handles on both sides of the outer box. This solves the problem of large gaps between the lid and the foam box during use and the easy loss of the lid during handling. It improves the sealing performance, insulation, efficiency, and practicality of the foam box. Multiple insulation layers are installed on the body to enhance the insulation effect. When the outer box of the foam box is subjected to external impact, the sponge blocks placed between the outer and inner boxes have good shock absorption, softness, and compressibility, and the pearl cotton has the functions of shock absorption, heat preservation, strong toughness, and strong impact resistance to prevent the foam box from being damaged. Then, the first and second shock-absorbing airbags installed inside the foam box solve the problem of goods being damaged by shaking and impacting back and forth inside the foam box during transportation. This achieves the foam box's anti-compression effect, enhances the practicality and flexibility of the foam box, improves the overall strength of the foam box, and improves the quality of the foam box.
