Description

airtight storage device

The invention relates to a storage device with an airtight function, especially an airtight cabinet/box/box.

Air-tight moisture-proof cabinets in the prior art usually have elastic sealing strips on the edge of the cabinet door or around the opening of the cabinet body. When the cabinet door is closed, the sealing strip will be pressed between the cabinet door and the cabinet body, thus sealing the cabinet. The gap between the door and the cabinet achieves a sealing effect.

However, the current cabinet door and the cabinet body are connected by a general door shaft, and the cabinet door rotates around the axis of the door shaft when opening and closing. However, in this case, the amount of movement of the cabinet door close to the door axis (i.e., the center of the circle) is much smaller than the amount of movement of the cabinet door away from the door axis. Therefore, the pressure effect of the cabinet door close to the door axis on the sealing strip is very limited, so As a result, the sealing strip there cannot effectively close the gap between the cabinet door and the cabinet body, thus affecting the overall sealing effect.

Therefore, the moisture-proof airtight cabinets of the prior art need to be improved.

In view of the aforementioned shortcomings and shortcomings of the prior art, the present invention provides an airtight storage device that can evenly compress the seal to improve the overall sealing effect.
