Problems solved by technology

[0003] One disadvantage of the above door frame sealing device is that in order to ensure that the sealing strip completely covers the sealed gap, the size of the sealing strip should cover all the gaps, but based on conventional design specifications, the size of the sealing strip often cannot cover larger gaps
In addition, due to the high rigidity of this type of sealing device, it can only make a limited response to the torque of the door surface, or to the unevenness of the door surface. A door gap that does not ensure a complete seal or does not meet the sealing requirements durably

Embodiment Construction

[0017] The present invention will be further described below through two design examples according to the present invention in conjunction with the drawings.

[0018] A door frame sealing device, used for sealing the gap between the door leaf and the door frame 1, is equipped with an installation part 2, and this sealing device is also a part of the door frame. The cross-sections of the mounting parts 2 are generally U-shaped, and the narrower built-in strips 9, which also have a U-shaped cross-section, extend into the mounting parts. 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 movable distance of the built-in strip 9 in the mounting part 2 is greater than the deformation of the shorter sealing part 6 .

Abstract

The invention relates to a door frame sealing device, and the device is used for sealing a gap between a door frame and a door leaf. The device comprises an installation part, and an installation groove which is used for installing a sealing strip, wherein the installation part is located in a metal, plastic or wood door frame, and the sealing strip consists of a fixed part and a sealing part. The device is characterized in that the fixed part of the sealing strip is disposed in an installation groove of a built-in strip; the built-in strip is disposed in the installation part, is installed on a closing surface in a closing direction, and can be impelled in a parallel manner. The device enables the gap between the door frame and the door surface to be sealed as durably and completely as possible, and is not affected by the torque of a door structure or the concave-convex parts of the door surface.

Description

technical field [0001] The invention relates to a sealing device for sealing the gap between a door frame and a door leaf. Background technique [0002] Patent "DE 67 52 894 U1" describes an existing door frame sealing device which comprises a mounting part and a mounting groove for fitting a sealing strip. The sealing strip is composed of a fixing part fixed in the installation groove and a sealing part covering the gap to be sealed, but the sealing part and the fixing part belong to a whole, that is, the sealing strip. [0003] The above-mentioned door frame sealing device has a disadvantage, that is, in order to ensure that the sealing strip completely covers the sealed gap, the size of the sealing strip should cover all the gaps, but based on conventional design specifications, the size of the sealing strip often cannot cover larger gaps. In addition, due to the high rigidity of this type of sealing device, it can only make a limited response to the torque of the door s...
