Description

Sealing structure of cold storage box door body

Technical Field

The utility model belongs to the technical field of the cold-storage box, a seal structure of cold-storage box door body is related to.

Background

The cold storage box is a convenient device for temporary refrigeration and heat preservation, is used for long-distance cold chain transportation of various refrigerated and frozen foods, and is also called as a heat preservation box or a cold storage box.

In order to ensure and prolong the heat preservation efficiency of the cold storage box, the mobile cold storage box which can be automatically refrigerated is manufactured by additionally arranging a refrigeration module in the box body by the existing manufacturers. The food in the cold storage box is refrigerated and insulated through the refrigeration module, so that the quality of the food is ensured. When food in the cold storage box is kept warm, the sealing effect of the cold storage box is required to be ensured, heat exchange between the inside of the cold storage box and the outside is blocked, and the heat preservation efficiency of the cold storage box is improved.

Since the door body of the regenerator is opened and closed, the sealing effect of the door body when closed determines the sealing effect of the regenerator, and thus the sealing effect of the door body needs to be ensured in order to improve the heat preservation efficiency of the regenerator. The existing sealing structure of the door body, such as the door structure of the cold-chain logistics transportation cold insulation box with the Chinese patent application number of CN201220587634.8, comprises a box door main body and a sealing rubber tube, wherein the sealing rubber tube is arranged at the edge of the inner side of the box door main body. An air bag made of rubber is also used in the field to seal the box body and the door body. This patent seals the opening border of box when the chamber door is closed through sealed rubber tube, has improved the sealed effect of chamber door. Although the structure that this patent was given can improve the leakproofness of a body to a certain extent, because the sealing rubber pipe only seals one, and directly laminate at the opening border plane of box, the sealing rubber pipe has the clearance easily with box sealing area is less to lead to leaking, especially uses the easy greatly reduced of back leakproofness for a long time, therefore the sealing effect of the door body among the prior art is not good.
