Description

Technical Field

[0001] This utility model belongs to the field of food preservation technology, specifically relating to a refrigerated food preservation box. Background Technology

[0002] In refrigerated transport, logistics boxes are important containers used to load goods. After the goods are placed in the logistics boxes, the boxes are sealed and stacked, and then the logistics boxes are placed on the transport vehicle for transport. In order to better preserve the goods, cold sources such as ice packs and dry ice are placed in the logistics boxes to lower the ambient temperature and refrigerate the goods.

[0003] However, during the above process, when taking out the goods that need to be taken out first or adding cold sources to the transport container, the transport container needs to be opened. When the transport container is opened, a large amount of cold air inside the transport container will be lost to the outside, causing the cold air around the goods to escape, which will cause the temperature inside the transport container to change. Moreover, when loading goods, multiple packaging units (packaging bags or packaging boxes) will be stacked and piled up, and there may be a situation where the goods at the bottom layer are squeezed by the goods at the top layer. Summary of the Invention

[0004] Based on this, this application provides a refrigerated and fresh-keeping box to solve the technical problems in the prior art where opening the transport box when taking out part of the goods results in a large loss of internal cold air and mutual compression of stacked goods.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] A refrigerated food storage box, comprising:

[0007] The box is used to hold goods;

[0008] A lid, on which a buckle is provided, fastens the lid to the box body for covering the goods inside the box body;

[0009] The support plate has several vertical through holes and is horizontally positioned inside the box to divide the box into several layers of accommodating space in the vertical direction. The through holes are used to connect two adjacent accommodating spaces.

[0010] Preferably, a buffer pad is fixed on the lower end surface of the support plate, and a round hole is opened at the corresponding position of the buffer pad and the through hole.

[0011] Preferably, the support plate has horizontally opened slides at its two symmetrical ends, and an extension frame is slidably connected in each slide.

[0012] Preferably, the support plate has a material inlet in the middle, and a material cover is fastened in the material inlet.

[0013] Preferably, the material cover has a hook groove for easy hooking with fingers.

[0014] Preferably, it further includes a connecting component disposed on the support plate for connecting the support plate to the side wall of the box.

[0015] Preferably, the connecting assembly includes a threaded rod and a plate rotatably connected to the outer end of the threaded rod, the threaded rod being connected to a threaded hole opened on the side of the support plate.

[0016] Preferably, an anti-slip pad capable of elastic deformation is fixed on the outer surface of the patch.

[0017] Preferably, the outer surface of the anti-slip pad is formed with a serrated structure, and the serrated structure is oriented downwards.

[0018] Preferably, it also includes a placement cavity for placing dry ice, which is located at the bottom of the box body.

[0019] Compared with the prior art, this application has at least the following advantages:

[0020] This application provides a refrigerated and fresh-keeping box that uses a support plate to separate stacked goods into layers, preventing the lower goods from being crushed due to stacking. Simultaneously, after the box is filled with cold air, when taking out a portion of the goods in batches, the lid is opened, the top layer of goods is removed, and then the lid is closed. During this process, although the lid is open, the air around the top layer of goods will escape outwards. However, the cold air below the support plate is blocked and restricted, and although some cold air will flow upwards through the vents, the loss is minimal. Compared to traditional transport boxes, this avoids the large-scale loss of cold air when the box is opened without any obstruction or restriction. The separation effect of the support plate reduces the loss of cold air in the space below, maintaining a stable temperature. Attached Figure Description

[0033] Please refer to Figures 1 to 8 In one specific embodiment of this application,

[0034] A refrigerated food storage box, comprising:

[0035] Box 101 is used to hold goods;

[0036] A cover 201 is provided with a buckle 202, which fastens the cover 201 onto the box 101 to cover the goods inside the box 101.

[0037] The support plate 301 has several vertical through holes 302, and the support plate 301 is horizontally arranged inside the box 101 to divide the box 101 in the vertical direction to form several layers of receiving space. The through holes 302 are used to connect two adjacent receiving spaces.

[0038] When loading goods, first place a cold source (dry ice, ice packs, etc.) into the box 101 (bottom, top, or side are all acceptable). Then, lay the goods that need to be removed last in the box 101. Next, move the support plate 301 into the box 101 and fix it horizontally to the inner wall of the box 101. The fixing method can be adhesive, screws, or corresponding connectors. This divides the internal space of the box 101 into multiple layers. During this process, the support plate 301 is lowered in the box 101 as close as possible to the goods laid at the bottom of the box 101, so that the space below the support plate 301 is filled with goods, reducing space waste. Then, load the goods that need to be removed earlier onto the support plate 301. The support plate 301 is used to separate the goods and allow the upper layer of goods to be loaded. The weight of the object acts on the support plate 301; the generated cold air passes through several through holes 302 and enters the space on both sides of the support plate 301, and finally the cover 201 is closed; the number of support plates 301 can be increased or decreased according to the actual number of times they are taken out. For example, if the goods put into the box 101 need to be taken out in two parts, then one support plate 301 is needed to divide the box 101 into two layers of space, and the goods to be taken out first are placed on the support plate 301, and the goods to be taken out later are placed below the support plate 301. If the goods put into the box 101 need to be taken out in three parts, then two support plates 301 are needed to divide the box 101 into three layers of space, the goods to be taken out last are placed below the support plate 301 on the lower side, the goods to be taken out second time are placed between the two support plates 301, the goods to be taken out first time are placed above the support plate 301 on the upper side, and so on.

[0039] By using the above method, when loading goods, the support plate 301 can be used to separate the goods that need to be stacked, avoiding the situation where the goods at the bottom are squeezed due to stacking. At the same time, after the cold air fills the box 101, when taking out some goods in batches, the lid 201 is opened, the top layer of goods is taken out, and then the lid 201 is closed. In this process, although the lid 201 is opened, the air around the top layer of goods will escape outward. However, the cold air under the support plate 301 is blocked and restricted by the support plate 301. Although some cold air will flow upward through the through hole 302, it is only a small amount of cold air loss. Compared with traditional transport boxes, it can avoid the large amount of cold air loss when the cold air is completely unobstructed and unrestricted when it is opened. By using the dividing effect of the support plate 301, the loss of cold air in the space under the support plate 301 is reduced, and the temperature is kept stable.

[0040] Meanwhile, a pressure relief valve 601 is provided on the box 101 or the cover 201. The pressure relief valve 601 is a one-way valve used to release the air pressure in the cover 201. The pressure relief valve 601 is connected to the space inside the cover 201. When a large amount of carbon dioxide is generated as the dry ice in the cover 201 sublimates, the air pressure in the cover 201 will increase. The pressure relief valve 601 can release the pressure to the outside in time to avoid excessive air pressure in the cover 201 and potential safety hazards.

[0041] In addition, during transportation, the goods may shake up and down inside the box 101 due to the bumps of the vehicle. When the goods shake upwards, they may come into contact with the support plate 301 and be damaged.

[0042] Therefore, in this application, a buffer pad 304 is fixed on the lower end surface of the support plate 301, and a round hole 310 is opened at the corresponding position of the buffer pad 304 and the through hole 302.

[0043] The cushioning pad 304 can be made of rubber or foam, or any material that can undergo elastic deformation. The function of the cushioning pad 304 is to cushion the goods when they come into contact with it, reducing the contact force with the support plate 301. The round hole 310 does not block the through hole 302, allowing the cold air above the support plate 301 to pass smoothly through the through hole 302 into the space below the support plate 301, which can reduce the damage caused by the goods shaking up and down. Similarly, the cushioning pad 304 can be laid on the inner wall of the box 101 for protection, further improving the protection effect of the goods.

[0044] The sizes of shipping containers vary, and their lengths differ depending on their specifications. To increase the support range of the pallet 301 and its ability to be used in shipping containers of different sizes, therefore...

[0045] In this application, the support plate 301 has horizontally opened slide rails 303 at two symmetrical ends, and each slide rail 303 is slidably connected to an extension frame 309.

[0046] During use, the extension frame 309 can be moved and extended in the slide 303 according to the size and length of the box 101, thereby changing the support range of the support plate 301. After adjustment, the support plate 301 can be fixed to the inner wall of the box 101 to complete the connection.

[0047] By means of the above method, the support range of the support plate 301 can be adaptively adjusted according to the change of the size of the box 101, so that the support plate 301 can support the goods according to the change of the size of the box 101, thereby improving the applicability and effectiveness of the support plate 301.

[0048] Furthermore, when removing goods located under the support plate 301, if the support plate 301 is removed entirely, this process requires detaching the support plate 301 from the box body 101. This process can be quite cumbersome, for example, separating the connection between the support plate 301 and the box body 101.

[0049] In this application, the support plate 301 has a feed opening 306 in the middle, and a feed cover 307 is fastened into the feed opening 306.

[0050] When removing goods from under the support plate 301, open the material cover 307, and you can directly remove the goods from under the support plate 301 through the material inlet 306. Conversely, you can also do this when loading goods.

[0051] Furthermore, the material cover 307 is provided with a hook groove 308 for easy hooking with fingers; the material cover 307 can be opened by directly hooking fingers into the hook groove 308.

[0052] By using the above method, goods under the support plate 301 can be quickly retrieved without disassembling the support plate 301, reducing the operation steps and difficulty when retrieving goods.

[0053] Specifically, an embodiment of the connection between the aforementioned support plate 301 and the inner wall of the box body 101 is provided:

[0054] This application also includes a connecting component, which is disposed on the support plate 301 and is used to connect the support plate 301 to the side wall of the box body 101.

[0055] The connecting components can be bolts or tape, as long as they can connect the support plate 301 to the inner wall of the box 101;

[0056] When in use, after moving the support plate 301 to a suitable position in the box 101, keep the support plate 301 horizontal, and then use the connecting assembly to connect the end of the support plate 301 to the inner wall of the box 101 to complete the fixation. For example, when using bolts for fixation, a threaded blind hole is opened on the inner wall at the end of the support plate 301, and then the bolt is screwed into the blind hole from the outside to the inside through the side wall of the box 101; or when using tape, the tape is simply stuck to the support plate 301 and the inner wall of the box 101.

[0057] Specifically, an embodiment of the above-mentioned connection component is provided:

[0058] The connecting assembly includes a threaded rod 401 and a plate 402 rotatably connected to the outer end of the threaded rod 401. The threaded rod 401 is connected to a threaded hole 305 opened on the side of the support plate 301.

[0059] During connection, after the support plate 301 is moved horizontally to a suitable height in the box 101, the threaded rod 401 can be rotated to move the mounting plate 402 away from the support plate 301. This causes the mounting plate 402 to approach and eventually contact the inner wall of the box 101. By using the threaded rod 401 to press the mounting plate 402 against the inner wall of the box 101, the support plate 301 is "locked" against the inner wall of the box 101, thus securing the support plate 301 within the box 101. Figure 8 Among them, the plate 402 is long and narrow, which can increase the contact area with the inner wall of the box 101, thereby increasing the friction between the plate 402 and the inner wall of the box 101, and making the connection between the plate 402 and the inner wall of the box 101 more stable.

[0060] The above method enables the connection and fixation of the support plate 301 without damaging the inner wall of the box 101, and facilitates operation during installation. Simply rotate the threaded rod 401 to move the mounting plate 402 to disassemble and install the support plate 301.

[0061] In addition, to further improve the friction between the mounting plate 402 and the inner wall of the box 101 after they are pressed together, therefore,

[0062] In this application, an anti-slip pad 403 capable of elastic deformation is fixed on the outer surface of the patch 402;

[0063] When the plate 402 approaches the inner wall of the box 101, it causes the anti-slip pad 403 to come into contact with the inner wall of the box 101. As the plate 402 continues to approach, it compresses the anti-slip pad 403, causing the anti-slip pad 403 to undergo elastic deformation, increasing the contact area with the inner wall of the box 101, increasing friction, and making the connection between the plate 402 and the inner wall of the box 101 more tight and stable.

[0064] Furthermore, the anti-slip pad 403 has a serrated structure formed on its outer surface, and the serrated structure is oriented downwards.

[0065] In other words, when the anti-slip mat 403 undergoes elastic deformation, it can increase the contact area with the inner wall of the box 101 and increase the friction. At the same time, when goods are placed on the support plate 301, the weight will increase, which will increase the downward sliding force (or tendency) of the anti-slip mat 403. Therefore, the downward serrated structure is used to increase the roughness of the inner wall of the box 101, further increasing the friction between the anti-slip mat 403 and the inner wall of the box 101, and improving the connection effect and stability.

[0066] In addition, dry ice is commonly used as a cold source in current shipping boxes. However, the dry ice needs to be wrapped in packaging before being placed in the shipping box. This not only wastes paper, but also makes it difficult to stably set up the dry ice. The dry ice is prone to shifting when the shipping box is shaken.

[0067] Therefore, this application also includes a placement cavity 501 for placing dry ice, which is located at the bottom of the box body 101;

[0068] The placement chamber 501 can be a box or a bag, into which dry ice can be filled and sealed. When the dry ice sublimates, the carbon dioxide produced can escape. Holes can be made in the box or bag to allow the carbon dioxide to flow out.

[0069] In other words, after fixing the placement cavity 501 to the inner bottom of the box body 101, the dry ice is placed into the placement cavity 501. This allows the dry ice to be restricted by the placement cavity 501, preventing it from contacting the goods and affecting them during the bumpy process, and also preventing the dry ice from falling out of the placement cavity 501.

[0070] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
