Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a packaging bag for cold chain preservation. Background Technology

[0002] Cold chain transportation requires low temperatures in medium- and long-distance transportation and short-distance delivery. It mainly involves low-temperature transportation vehicles such as refrigerated railway cars, refrigerated trucks, refrigerated ships, and refrigerated containers. During refrigerated transportation, temperature fluctuations are one of the main causes of the decline in the quality of goods. Therefore, transportation vehicles should have good performance and maintain stable temperatures while keeping the specified low temperatures. This is especially important for long-distance transportation. Currently, the packaging bags used for transporting fresh produce are all ordinary plastic bags. Traditional packaging bags used for cold chain preservation have some drawbacks. Currently, fresh food is transported in the cold chain without any protective measures. Therefore, in the event of an emergency, the cooling temperature of the cold chain may drop, which can easily damage the fresh food and make it inconvenient to transport. Utility Model Content

[0003] The main objective of this invention is to provide a packaging bag for cold chain preservation, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A packaging bag for cold chain preservation includes a main body of the packaging bag. An auxiliary placement mechanism is provided on the inner side of the main body of the packaging bag. The auxiliary placement mechanism includes a fixed frame fixedly connected to the inner side of the main body of the packaging bag. A placement groove is formed at the upper end of the fixed frame. A limiting frame is placed inside the placement groove. A placement rack is fixedly connected to the inner side of the limiting frame. A ventilation groove is formed at the upper end of the placement rack. A positioning hole is formed at the upper end of the limiting frame. A limiting rod is movably connected to the inner side of the positioning hole. A limiting head is fixedly connected to the upper end of the limiting rod. A collection chamber is fixedly connected to the lower end of the fixed frame.

[0005] Preferably, a baffle plate is fixedly connected to the inner wall of the collection chamber, and a distribution chamber is fixedly connected to the bottom of the inner side of the collection chamber.

[0006] Preferably, the placement rack is located inside the fixed frame and above the collection chamber.

[0007] Preferably, there are multiple sets of ventilation grooves, the lower end of the limiting rod is fixedly connected to the inner bottom of the placement groove, the main body of the limiting head is frustum-shaped, and the main body of the limiting rod and the limiting head are both made of rubber.

[0008] Preferably, the front end of the baffle plate is fixedly connected to the rear end of the distribution compartment, and there are two sets of baffle plates. The distribution compartment is located below the placement frame.

[0009] Preferably, a handle is fixedly connected to the inner wall of the main body of the packaging bag. The handle is U-shaped and there are two sets of handles, which are centrally symmetrically distributed.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By placing ice blocks into the collection chamber and then placing the limiting frame into the placement slot, with the positioning hole locked on the outside of the limiting rod, the limiting head restricts the limiting frame within the placement slot. This allows the ice blocks in the collection chamber to pass through the ventilation slot to cool the items, enabling temporary cooling of the items. This allows the items to be transported in a cooler environment and prevents damage. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4As shown, a packaging bag for cold chain preservation includes a packaging bag body 1. An auxiliary placement mechanism 3 is provided on the inner side of the packaging bag body 1. The auxiliary placement mechanism 3 includes a fixing frame 31 fixedly connected to the inner side of the packaging bag body 1. A placement groove 32 is opened at the upper end of the fixing frame 31. A limiting frame 33 is placed inside the placement groove 32. A placement frame 34 is fixedly connected to the inner side of the limiting frame 33. A ventilation groove 35 is opened at the upper end of the placement frame 34. A positioning hole 36 is opened at the upper end of the limiting frame 33. A limiting rod 37 is movably connected to the inner side of the positioning hole 36. A limiting head 38 is fixedly connected to the upper end of the limiting rod 37. A collection chamber 39 is fixedly connected to the lower end of the fixing frame 31.

[0015] In this embodiment, a baffle plate 310 is fixedly connected to the inner wall of the collection chamber 39, and a distribution chamber 311 is fixedly connected to the bottom of the inner side of the collection chamber 39. The placement rack 34 is located inside the fixed rack 31 and above the collection chamber 39. There are multiple sets of ventilation slots 35. The lower end of the limiting rod 37 is fixedly connected to the bottom of the inner side of the placement slot 32. The main body of the limiting head 38 is truncated cone-shaped. The main body of the limiting rod 37 and the limiting head 38 are both made of rubber. The front end of the baffle plate 310 is fixedly connected to the rear end of the distribution chamber 311. There are two sets of baffle plates 310. The distribution chamber 311 is located below the placement rack 34.

[0016] Specifically, first, lift the placement rack 34 upwards, causing the limiting rack 33 to disengage from the placement slot 32 and the positioning hole 36 to disengage from the outside of the limiting rod 37. Then, place ice blocks into the collection chamber 39 and the distribution chamber 311. Next, place the limiting rack 33 into the placement slot 32, causing the positioning hole 36 to engage with the outside of the limiting rod 37 and the limiting head 38 to fix the limiting rack 33, thus securing the limiting rack 33 within the placement slot 32. Then, place the items into the packaging bag body 1 and onto the placement rack 34. If the refrigerated truck encounters an emergency, it will be unable to cool the packaging bag body 1, thereby preventing the contents of the collection chamber 39 and the distribution chamber 311 from cooling down. Ice blocks cool the surrounding environment and allow cold air to pass through the ventilation channel 35 to cool the items, thus enabling the items to be transported in a cooler environment and preventing damage. By placing ice blocks into the collection chamber 39 and then placing the limiting frame 33 into the placement slot 32, with the positioning hole 36 engaging the outside of the limiting rod 37, the limiting head 38 restricts the limiting frame 33 within the placement slot 32. This facilitates the cooling of the items by the ice blocks in the collection chamber 39 through the ventilation channel 35, allowing the ice blocks to temporarily cool the items and enabling them to be transported in a cooler environment, thus preventing damage.

[0017] In this embodiment, a handle 2 is fixedly connected to the inner wall of the main body 1 of the packaging bag. The handle 2 is U-shaped and there are two sets of handles 2, which are centrally symmetrically distributed.

[0018] Specifically, by lifting the two sets of handles 2, the main body of the packaging bag 1 is moved and placed into the cold chain vehicle, and the cold chain vehicle transports the main body of the packaging bag 1.

[0019] Working principle: In use, first lift the placement rack 34 upwards, which will disengage the limiting rack 33 from the placement slot 32 and disengage the positioning hole 36 from the outside of the limiting rod 37. Then place ice blocks in the collection chamber 39 and the distribution chamber 311. Next, place the limiting rack 33 into the placement slot 32, which will cause the positioning hole 36 to engage with the outside of the limiting rod 37 and the limiting head 38 to be fixed on the limiting rack 33, thus securing the limiting rack 33 within the placement slot 32. Then, place the items into the packaging bag body 1 and onto the placement rack 34. Finally, lift the two sets of handles 2 to move the packaging bag body 1 and place it into the cold chain truck, allowing the cold chain truck to transport the packaging bag body 1. If the cold chain truck encounters an emergency, it will be unable to transport the packaging bag body 1. The main body 1 of the packaging bag is cooled, which in turn cools the surrounding environment by allowing the ice in the collection chamber 39 and the distribution chamber 311 to cool the items through the ventilation channel 35. This allows the items to be transported in a cooler environment and prevents them from being damaged. By placing the ice in the collection chamber 39 and then placing the limiting frame 33 in the placement slot 32, with the positioning hole 36 engaging the outside of the limiting rod 37, the limiting head 38 restricts the limiting frame 33 within the placement slot 32. This allows the ice in the collection chamber 39 to cool the items through the ventilation channel 35, providing temporary cooling for the items. This allows the items to be transported in a cooler environment and prevents them from being damaged.
