In the prior art, a heat preservation box is generally used with a cold storage body such as an ice bag and an ice box. A cold storage body is placed in the heat preservation box, and the refrigerant in the cold storage body maintains a relatively constant temperature in the box by absorbing or releasing heat. However, during the heat preservation process, as the heat exchange between the refrigerant and the goods, the heat absorption of the refrigerant gradually melts. In order to maintain the temperature environment in the heat preservation box and ensure the heat preservation effect, the cold storage body needs to be replaced in time.

In the prior art, when replacing the cold storage body, the cover needs to be opened first, the cold storage body to be replaced is taken out from the box body, and then the new cold storage body is put into the box body, and finally the cover body is covered. The operation steps are relatively many. The time taken is relatively long; during the process of replacing the cold storage body, the goods in the box contact the outside air and perform heat exchange, resulting in the deterioration of the quality of the goods. The longer the replacement process, the more heat exchange between the goods and the outside air The more it has, the greater the adverse effect on the quality of the goods; moreover, the operation steps are relatively more complicated, which is not conducive to the automation of the replacement operation.

The cold storage plugging device provided in this embodiment can effectively alleviate the technical problem that the operation steps of replacing the cold storage body take a long time. The cold storage plugging device provided in this embodiment will be described in detail below.
