Description

Technical Field

[0001] The utility model belongs to the technical field of seaborne packaging boxes, and in particular relates to a seaborne anti-corrosion packaging box with a heat insulation function. Background Art

[0002] Packing boxes are mainly for the convenience of transportation, loading and unloading and storage. Generally, wooden boxes and corrugated wood pallets are used. Tin barrels or tin barrels are also used. Using biodegradable materials to make packing boxes can protect the environment.

[0003] Since conventional insulated packaging boxes mainly use insulating materials such as foam to reduce temperature transmission, the effect is far lower than that of vacuum insulation, and the cost of making the box board into a vacuum is relatively high and it occupies a relatively large space, resulting in the problem of low practicality of conventional insulated packaging boxes.

[0004] To this end, we propose a seaborne anti-corrosion packaging box with heat insulation function to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low practicability of conventional heat-insulating packaging boxes and proposes a seaborne anti-corrosion packaging box with a heat-insulating function.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A seaborne anticorrosive packaging box with heat insulation function comprises a box body and a sealing cover, wherein the sealing cover is matched with the box body sealing cover, a sealing plug is slidably installed on the inner end of the sealing cover, the lower end of the sealing plug is sealed and matched with the opening of the sealing cover, and a conical spring is connected between the sealing cover and the sealing plug. The product is placed in the box body, and then the sealing cover is covered on the box body, and then the air in the box body is extracted through the opening on the sealing cover with the help of an air pump, so that the inside of the box body is close to vacuum, and after removing the air pump, the atmospheric pressure is used to act on the sealing plug, so that the sealing plug is firmly sealed at the opening of the sealing cover; by reducing the air content inside the box body, reducing heat transfer, and extending the internal low temperature time, the quasi-vacuum state is used to reduce the bacterial reproduction rate, thereby extending the product anticorrosion time and improving practicality.

[0008] Preferably, a first reinforcement frame is fixedly connected to the middle of the inner side of the sealing cover, and the first reinforcement frame is plugged and matched with the opening of the box body. When the sealing cover is closed with the box body, the first reinforcement frame is embedded in the opening of the box body. When a high negative pressure is formed inside the box body, the first reinforcement frame is used to increase the compressive strength of the sealing cover and improve the structural stability of the sealing cover.

[0009] Preferably, the box includes an outer shell and a second reinforcement frame, and the second reinforcement frame is fixedly connected to the inner end of the outer shell. The second reinforcement frame is used to increase the compressive strength of the outer shell, and the second reinforcement frame is used to reduce the heat conduction contact surface of the product, thereby reducing low-temperature loss.

[0010] Preferably, the box body further comprises a support plate, which is fixedly connected to the lower end of the shell. The support plate is used to increase the placement range of the box body, making it convenient to stack and place it with the sealing cover.

[0011] Preferably, the sealing cover comprises a cover body and an air extraction pipe, wherein the air extraction pipe penetrates the cover body and is fixedly connected to the cover body. An external air extraction pump is convenient for extracting air from the box body through the air extraction pipe.

[0012] Preferably, the sealing cover further comprises a support frame, and the support frame is fixedly connected to the upper end of the cover body. When another device is stacked on the sealing cover, the support frame is used to support the box of the other device, so as to conveniently protect the exhaust pipe.

[0013] Preferably, the sealing plug includes a pull button, a slider and a sealing ring, the lower end of the pull button is fixedly connected to the slider, and the sealing ring is fixedly connected to the lower end of the slider. Pulling the pull button upwards overcomes the negative pressure inside the sealing ring, separates the sealing ring from the exhaust pipe, allows gas to enter the box, neutralizes the internal negative pressure, and facilitates opening the sealing cover again.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Place the product in the box, then cover the box with the sealing cover, and then use a vacuum pump to extract the air in the box through the opening on the sealing cover to make the inside of the box close to a vacuum. After removing the vacuum pump, use atmospheric pressure to act on the sealing plug to seal the sealing plug firmly at the opening of the sealing cover. By reducing the air content inside the box, reducing heat transfer, and extending the internal low temperature time, while utilizing a quasi-vacuum state to reduce the bacterial reproduction rate, the product preservation time is extended and practicality is improved.

[0016] 2. When the sealing cover is closed with the box body, the first reinforcement frame is embedded in the opening of the box body. When a high negative pressure is formed inside the box body, the first reinforcement frame is used to increase the compressive strength of the sealing cover and improve the structural stability of the sealing cover.

[0017] 3. Use the second reinforcement frame to increase the compressive strength of the shell, and at the same time use the second reinforcement frame to reduce the thermal contact surface of the product, so as to reduce low-temperature loss.

[0018] 4. Pull the button upward to overcome the negative pressure on the inner part of the sealing ring, separate the sealing ring from the exhaust pipe, allow the gas to enter the box, neutralize the internal negative pressure, and facilitate opening the sealing cover again.
