Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, in particular to a sealing structure for a sliding door. Background Art

[0002] A sliding door is a commonly used door in a home, which refers to a door that can be pushed and pulled. A lift-sliding door is a type of sliding door. The lift-sliding door uses the principle of lever mechanics to control the lifting and lowering of the door leaf by turning the handle, thereby fixing and opening the door leaf.

[0003] During the use of lift-sliding doors, rubber strips are used as sealing materials between the frame and sash profiles. When the door sash is closed, it will move downward, so the sealing strips overlap the back of the track, thus forming a seal between the frame and sash. However, the door sash needs to pass through the track from the front during installation. In order to avoid excessive friction between the strips and the track during installation, which may cause wear on the surface of the strips, the overlap amount of the strips is usually designed to be very small, resulting in a reduced sealing effect when the door sash is closed. Based on this, a sliding door sealing structure is now provided that can eliminate the disadvantages of existing devices. Utility Model Content

[0060] The upper rail 201 is then moved to slide along the inner wall of the upper rail 201 by pushing the connecting push rod 202. During this process, the dust shield 203 and the moving push plate 204 are moved synchronously under the drive of the connecting push rod 202. The dust shield 203 can always cover the port of the upper rail 201 to prevent external dust from entering the interior of the upper rail 201. At the same time, the moving push plate 204 can move so that the inner wall of the other side of the sliding groove 205 can contact the outer wall of the positioning plug 207. At the same time, the fixed card plate 209 is inserted into the interior of the positioning plug 207 under the drive of the moving push plate 204, so that the fixed card plate 209 can be engaged with the positioning plug 207, so that the upper rail 201 can be engaged and limited, effectively preventing the upper rail 201 from automatically falling off.

[0061] Then, use tools to make two bolts 206 pass through the upper slide rail 201 and threadedly connect it with the fixing plate 208, so that the upper slide rail 201 can be fixed by the two bolts 206, and then repeat the operation on the other sliding door body 4, so as to achieve efficient installation of the sliding door body 4, while further improving the sealing effect of the sliding door body 4, and effectively avoiding the problem of difficulty in installing the sliding door body 4 due to excessive overlap of the rubber strips.
