Description

Technical Field

[0002] Sliding doors are doors that can be opened and closed by pushing or pulling the door body. This type of door is widely used in various buildings and places, such as residences, shopping malls, office buildings, hotels, etc. The advantages of sliding doors include maximizing space saving, facilitating the functional division and utilization of the room, and having great advantages in lighting, sound insulation, blocking sight, enhancing decoration, etc., to meet different space requirements. In order to facilitate the movement of sliding doors and ensure smoothness during movement, when installing sliding doors, sliding rails are generally added to the door frame for the sliding door to move in and out.

[0003] However, since the sliding rail and door frame are generally fixed together, the door leaf needs to pass through the track from the front during installation. In order to avoid excessive friction between the rubber strip and the track during installation, the overlap amount of the full-length rubber strip is designed to be very small, which can easily cause the door leaf and the rubber strip to be squeezed during installation, resulting in poor sealing when the door leaf is closed.
