Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a sealing strip for a rolling shutter door. Background Technique

[0002] The sealing strip is mainly used to ensure that the door can fit tightly when closed, prevent the intrusion of external factors such as wind, rain, dust, and noise, and also helps to maintain the temperature and humidity inside the room.

[0003] Common sealing strips for rolling shutter doors generally install connecting plates on the surface for installation at the bottom of the rolling shutter door. The pressure generated by the downward movement of the rolling shutter door is used to closely contact the sealing strip with the ground, thereby sealing the bottom of the rolling shutter door.

[0004] However, since the traditional sealing strip is installed on the rolling shutter door with a single connecting plate and only a single surface contacts the rolling shutter door, when the rolling shutter door squeezes the sealing strip, the sealing strip will be inclined to both sides under the extrusion force, resulting in the sealing strip shifting and falling off from the surface of the rolling shutter door. In order to improve the sealing performance of the sealing strip, the rolling shutter door will apply a greater pressure to the sealing strip. However, the compression ratio of the traditional sealing strip is relatively low, resulting in a smaller contact area between the sealing strip and the ground, and the sealing effect on the rolling shutter door will also decrease accordingly. At the same time, if there are foreign objects on the ground, the sealing strip will collide with the foreign objects, causing damage to the sealing strip. Since the rolling shutter door is generally made of metal, the moisture in the ground is easily adsorbed on the surface of the sealing strip, which is likely to cause corrosion to the sealing strip and the rolling shutter door. Content of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a sealing strip for a rolling shutter door to solve the problems raised in the above background technique, that is, the sealing strip will be inclined to both sides under the extrusion force, resulting in the sealing strip shifting and falling off from the surface of the rolling shutter door. In order to improve the sealing performance of the sealing strip, the rolling shutter door will apply a greater pressure to the sealing strip. However, the compression ratio of the traditional sealing strip is relatively low, resulting in a smaller contact area between the sealing strip and the ground, and the sealing effect on the rolling shutter door will also decrease accordingly. Moreover, when there are foreign objects on the ground, the sealing strip will collide with the foreign objects, causing damage to the sealing strip. At the same time, since the rolling shutter door is generally made of metal, the moisture in the ground is easily adsorbed on the surface of the sealing strip, which is likely to cause corrosion to the sealing strip and the rolling shutter door.
