Problems solved by technology

[0003] One disadvantage of the above-mentioned sealing system is that in order to ensure that the sealing strip completely covers the sealed gap, the size of the sealing strip is required to be relatively large, so the sealing strip will be greatly deformed under working conditions, and it will cause serious wear and tear on the sealing device
In addition, this type of rigid sealing device can only make a limited response to the torque of the door leaf, or to the deformation of the door leaf such as protrusions or depressions. Therefore, it cannot ensure full sealing for wider door gaps. Sealing, or not durably meeting sealing requirements

Embodiment Construction

[0019] The gap sealing device of the present invention will be further described below through two embodiments with reference to the accompanying drawings.

[0020] The gap sealing device of the present invention, if used to seal the gap between the door leaf and the door frame, then consists of the fixing strip 1, and if used to seal the gap between the two door leaves, then consists of the fixing strip 2. Both fixing strips 1 and 2 are approximately U-shaped in cross-section, while the narrower built-in strip 9 , which also has a U-shaped cross-section, extends into the fixing strip. An installation groove 3 is provided in the built-in strip 9 for installing the sealing strip 4, and the sealing strip 4 is composed of a fixed part 5 and a shorter sealing part 6, and the fixed part 5 is installed in the installation groove 3 of the built-in strip 9. The possible elastic movement distance of the built-in strip 9 in the fixed strips 1 and 2 is greater than the deformation of the...

Abstract

The present invention relates to gap seal device for sealing a gap between a door frame and a door leaf or a gap between two door leaves. Te gap seal device includes a fixed strip, a seal strip comprising a fixed portion and a seal portion, a mounting groove for mounting the seal strip, and a house; the fixed portion of the seal strip is inserted into the mounting groove of a built-in strip, and the built-in strip positioned in the fixed strip is mounted on a door close face of a door, and can be parallelly pushed forward. The gap seal device allows the gap between a door frame and a door leaf or a gap between two door leaves to be sealed permanently, effectively and completely avoid the influence of door leaf torque and bump deformation of the door.

Description

technical field [0001] The invention relates to a device for sealing a gap between a door frame and a door leaf or a gap between two door leaves. Background technique [0002] Existing anti-smoke systems, such as those described in patent "DE 10 2004 040 749 A1", comprise a fixing strip, a mounting groove for mounting the sealing strip and a housing. Wherein, the sealing strip is composed of a fixing part for fixing the position and a sealing part for sealing the gap, and the sealing part and the fixing part belong to a whole. [0003] One disadvantage of the above-mentioned sealing system is that in order to ensure that the sealing strip completely covers the sealed gap, the size of the sealing strip is required to be relatively large, so the sealing strip will be greatly deformed under working conditions, and it will cause serious wear and tear on the sealing device . In addition, this type of rigid sealing device can only make a limited response to the torque of the doo...
