Abstract
Description
Technical Field
[0001] This utility model relates to the field of food transport box technology, and in particular to a moisture-proof and pressure-proof transport box for pre-packaged food. Background Technology
[0002] A moisture-proof and pressure-resistant food transport box is a packaging container specially designed to protect food from moisture and pressure during transportation. Therefore, one food transport box, with publication number CN220810504U, separates ice packs from agricultural products, preventing the agricultural products from being squeezed or collided with the ice packs during transportation to the testing site, or from spoiling due to condensation. The box features internal water-filled plugs that block the cold air vents. When the box shakes or tilts during transportation, the plugs slide in the direction of the shaking or tilting, thus blocking the cold air vents and preventing condensation from melting in the ice pack compartment from seeping into the agricultural product compartment, effectively preventing spoilage of the agricultural products placed in the agricultural product compartment due to condensation.
[0003] However, during transportation, the transport box may encounter various bumps and shakes, causing the condensate produced by the melting ice packs to shake violently inside the ice pack storage compartment, producing splashing water droplets. Although the plug can slide to seal the cold air exhaust holes, it may not be able to completely cover all the holes during violent shaking, resulting in some gaps being exposed, allowing condensate droplets to splash into the agricultural product storage compartment.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] like Figures 1-4As shown, a pre-packaged food moisture-proof and pressure-proof transport box includes an insulated storage box 1 for food storage. During the transportation of the food, it is placed inside the insulated storage box 1. The bottom of the insulated storage box 1 has several cold air channels 7. Cold air generated by ice packs enters the insulated storage box 1 from bottom to top through the cold air channels 7, creating a low-temperature storage environment. The bottom of the insulated storage box 1 is covered with a one-way water-locking and breathable paper 8 covering the several cold air channels 7. A pressure frame 18 is fixedly installed below the one-way water-locking and breathable paper 8. The pressure frame 18 is set along the edge of the surface of the one-way water-locking and breathable paper 8 and is bolted to the four corners of the bottom of the insulated storage box 1. The bolts pass through the pressure frame 18 and the one-way water-locking and breathable paper 8 and are threadedly connected to the bottom of the insulated storage box 1, so that the pressure frame 18 can press the one-way water-locking and breathable paper tightly. 8. The edges are protected by a one-way water-locking and breathable paper 8 to prevent moisture from evaporating and entering the insulated storage box 1 from the bottom, without affecting the entry of cold air, thus achieving moisture protection for goods. An insulated bottom box 2 for storing ice packs is located below the insulated storage box 1. The opening of the bottom box 2 is located on the side, and its upper surface extends through and connects to the interior of the insulated storage box 1. By placing ice packs inside the bottom box 2, the cold air generated by the ice packs enters the insulated storage box 1 through the one-way water-locking and breathable paper 8. Both the openings of the insulated storage box 1 and the bottom box 2 are hinged with insulated covers 3. The insulated storage box 1 and the bottom box 2 used in this solution achieve their thermal insulation function through known means, such as setting an internal interlayer filled with insulation cotton or other thermal insulation materials.
[0023] Insulated storage box 1 has inserts 5 fixedly installed on its inner wall between two adjacent cold air slots 7. Insulated bottom box 2 has inserts 9 fixedly installed on its inner wall facing the side opening, directly below each insert 5. Insulated storage box 1 has an insulation partition 6 that connects to the inserts 5. Insulated bottom box 2 has an insulation board 10 that connects to the inserts 9. The insulation partition 6 and insulation board 10 can effectively divide the space inside insulated storage box 1 and insulated bottom box 2. The position of insulation partition 6 and insulation board 10 can be adjusted according to the size of the goods and by using the inserts 5 and inserts 9 to ensure that the environment in the goods area is minimized. Therefore, the cold air generated by the ice pack does not need to cover a large space inside insulated storage box 1, which can extend the use time of the ice pack and ensure effective low-temperature preservation of the contents inside insulated storage box 1.
[0024] The insert 5 has an insertion hole 4 on the side facing the inside of the insulated storage box 1. A central groove 12 is formed at the center of the top edge of the insulation partition 6, and slots 11 for insertion into the insert 5 are formed on both vertical sides of the insulation partition 6. Insert posts 13 for insertion into the insertion hole 4 are embedded at the same height on opposite side walls of the central groove 12. The two insert posts 13 are horizontally positioned, and inclined frames 14 are fixedly installed at opposite ends of each insert post 13. A spring rod 17 is fixedly installed at the center of the bottom of the central groove 12. The telescopic end of the spring rod 17 faces upward and is fixedly installed with a lifting seat 15 that inserts into the inner wall of the central groove 12. Both ends of the lifting seat 15 are respectively inserted into the inner walls of the two inclined frames 14. A hinged arm 16 is hinged to the top edge of the lifting seat 15. Figure 4 The spring rod 17 ensures the stability of the lifting seat 15, and the insertion of the pin 13 into the insertion hole 4 fixes the relative position of the insulation partition 6 and the insert strip 5. When moving the position of the insulation partition 6, simply move the hinge arm 16 upward to the vertical position and then press the hinge arm 16 downward to make the lifting seat 15 overcome the pushing force of the spring rod 17 and descend. By inserting the lifting seat 15 into the inner wall of the inclined frame 14, the two inclined frames 14 are forced to move closer to each other when the lifting seat 15 descends, thereby making the two pins 13 move closer to each other and disengage from the insertion hole 4, which makes it convenient for personnel to pull out the insulation partition 6 and adjust its position.
[0025] Working principle: When in use, adjust the position of the insulation partition 6 and insulation board 10 according to the size of the goods, place the goods in the insulated storage box 1, and put the ice pack in the insulated bottom box 2. The cold air generated by the ice pack enters the insulated storage box 1 through the one-way water-locking and breathable paper 8 and the cold air channel 7 and gathers around the goods to achieve low-temperature storage of the goods.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
