Description

Technical Field

[0001] The utility model belongs to the field of sealed doors, in particular to a sealed door with an embedded sealing strip. Background Art

[0002] A sealed door is a door with good sealing performance, which can effectively prevent air, water vapor, dust and other foreign substances from entering the room. Sealed doors are usually used in places where the indoor environment needs to be kept dry, clean and quiet, such as laboratories, hospital operating rooms, clean rooms, etc. The sealing performance of a sealed door depends on the design and material of the door frame, door leaf and sealing strip. Rubber sealing strips or magnetic sealing strips are usually used to achieve the sealing effect. Generally, a sealed door has only one sealing strip. In areas with strong winds and sand, the sealing effect is limited. In addition, the sealing strip is often pasted on the sealed door, which is easy to fall off and inconvenient to use.
