Description

Technical Field

[0001] This utility model relates to the field of cold chain packaging, and more specifically, to a pressure-resistant cold chain packaging box. Background Technology

[0002] Cold chain refers to a special supply chain system in which certain food raw materials, processed food or semi-finished products, special biological products and pharmaceuticals are kept in a specific low-temperature environment necessary for the product at all stages of product processing, storage, transportation, distribution and retail, and use, after being acquired, processed and inactivated, in order to reduce losses, prevent contamination and deterioration, and ensure the safety of food, biosafety and pharmaceuticals.

[0003] In existing technologies, cold chain transportation requires cold chain packaging of goods. However, cold chain packaging boxes are generally made of foam material. Although it can meet the needs of heat preservation and freshness preservation to a certain extent, its pressure resistance is low and it is easily damaged by impact and squeezing. At the same time, since the slots for placing items in cold chain packaging boxes are fixed, it is not possible to package according to the quantity of items. Multiple cold chain packaging boxes must be used for packaging, which increases the time spent and reduces packaging efficiency.

[0004] Therefore, we made improvements and proposed a pressure-resistant cold chain packaging box. Utility Model Content

[0005] The purpose of this utility model is to address the current problem of cold chain packaging boxes having low pressure resistance, being easily damaged by impact and squeezing, making it impossible to package according to the quantity of items, increasing the time spent, and reducing packaging efficiency.

[0006] In order to achieve the above-mentioned utility model objectives and improve the above-mentioned problems, the present utility model provides a pressure-resistant cold chain packaging box, including a packaging box, a cushioning component, and a placement component. The packaging box is provided with a cushioning component to prevent the packaging box from being squeezed, and the inner side of the cushioning component is provided with a placement component for facilitating the placement of items.

[0007] The buffer assembly includes multiple telescopic columns installed inside the packaging box. A pressure-resistant plate is fixedly connected to the top of each telescopic column. Multiple fixed plates are rotatably connected to both sides of the pressure-resistant plate. The multiple fixed plates are hinged together by connecting plates.

[0008] As a preferred technical solution of this application, the plurality of telescopic columns and the pressure-resistant plate are fixedly connected by telescopic springs.

[0009] As a preferred technical solution of this application, a support plate is fixedly connected to the other end of the plurality of telescopic columns.

[0010] As a preferred technical solution of this application, the bottom end of the pressure-resistant plate is slidably connected to the packaging box.

[0011] As a preferred technical solution of this application, the placement component includes a push block fixedly connected to the inner side of the fixed plate, a fixed rod fixedly connected to the upper part of the push block, and a clamping plate fixedly connected to one end of the fixed rod.

[0012] As a preferred technical solution of this application, the pusher block adopts a ladder structure.

[0013] As a preferred technical solution of this application, a partition block is fixed in the middle of the clamping plate.

[0014] As a preferred technical solution of this application, the fixing rod is provided in several forms.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. By using the telescopic column, support plate and fixed plate, when the push block slides, it squeezes the telescopic column and spring, which drives the fixed plate to rotate and stretch, thereby supporting the support plate and stabilizing the placement of items. This improves the pressure resistance of cold chain packaging boxes and increases the stability of item placement. It solves the problem of low pressure resistance in existing technologies, which makes the cold chain packaging boxes susceptible to impact and squeezing, resulting in damage to the items inside.

[0018] 2. By using the set separators, fixing rods, and clamps, items are placed between the separators on the clamps. As the quantity increases, the clamps are pushed, and the fixing rods cause the push blocks to slide, expanding the placement range inside the packaging box. This achieves flexible placement of items, improves placement efficiency, and solves the problem in existing technologies that cannot be packaged according to the quantity of items, which increases the time spent and reduces packaging efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 A pressure-resistant cold chain packaging box includes a packaging box 1, a cushioning component 2, and a placement component 3. The packaging box 1 is provided with a cushioning component 2 to prevent the packaging box from being squeezed, and the inner side of the cushioning component 2 is provided with a placement component 3 for easy placement of items.

[0030] The buffer assembly 2 includes multiple telescopic columns 201 disposed inside the packaging box 1. The top of the multiple telescopic columns 201 is fixedly connected to a pressure-resistant plate 202. Multiple fixed plates 203 are rotatably connected to both sides of the pressure-resistant plate 202. The multiple fixed plates 203 are hinged together by a connecting plate 204. When the pusher block 301 slides inside the packaging box 1 on both sides, it begins to squeeze the telescopic column 201, causing the telescopic column 201 to contract and squeeze the telescopic spring 4. The telescopic spring 4 then contracts, and the elastic force of the telescopic spring 4 and the pushing force of the pusher block 301 squeezing the telescopic column 201 support the support plate 5 at the other end of the telescopic column 201. This prevents the pressure applied from the outside from being resisted by the support plate 5. At the same time, the pushing of the pusher block 301 will cause multiple fixed plates 203 to hinge and rotate on the connecting plate 204, thereby increasing the angle between the fixed plate 203 and the connecting plate 204. This puts the fixed plate 203 in a stretched state on the connecting plate 204, stabilizing the placement of the items, improving the pressure resistance of the cold chain packaging box, and increasing the stability of the items.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the placement component 3 includes a push block 301 fixedly connected to the inner side of the fixed plate 203, a fixed rod 302 fixedly connected to the upper part of the push block 301, and a clamping plate 303 fixedly connected to one end of the fixed rod 302. Items to be placed are placed between each partition block 6 of the clamping plate 303. As the number of items increases, the items will begin to push the clamping plate 303. Subsequently, the clamping plate 303, through the fixed rod 302, further pushes the push block 301 to slide on both sides inside the packaging box 1, thereby expanding the area for placing items, enabling flexible placement and improving placement efficiency.

[0032] The use process of the pressure-resistant cold chain packaging box provided by this utility model is as follows:

[0033] The items to be placed are placed between each partition block 6 of the clamping plate 303. As the number of items increases, the items will begin to push the clamping plate 303. Subsequently, the clamping plate 303 further pushes the push block 301 to slide on both sides inside the packaging box 1 through the fixing rod 302, thereby expanding the range of items to be placed. When the push block 301 slides on both sides inside the packaging box 1, the push block 301 begins to squeeze the telescopic column 201, causing the telescopic column 201 to begin to contract and squeeze the telescopic spring 4, causing the telescopic spring 4 to begin to contract. Then, the elastic force of the telescopic spring 4 and the pushing force of the push block 301 squeezing the telescopic column 201 support the support plate 5 at the other end of the telescopic column 201, so that the pressure applied from the outside will be resisted by the support plate 5. At the same time, the pushing of the push block 301 will drive multiple fixing plates 203 to hinge and rotate on the connecting plate 204, thereby increasing the angle between the fixing plate 203 and the connecting plate 204, so that the fixing plate 203 is in a stretched state on the connecting plate 204, stabilizing the placement of items.
