TECHNICAL FIELD
[0001] The application belongs to the technical field of sliding doors and windows, and particularly relates to a full-embedded anti-storm sliding door and window system. BACKGROUND
[0002] Sliding windows are a common type of window, usually consisting of two or more moving sashes. One sash of this window can be pushed towards the other sash, or can be pulled back to a fixed position, to open or close the window. Sliding windows can be opened without occupying indoor or outdoor space, which means that they do not hinder indoor or outdoor activities, and have the advantage of not occupying indoor space. In addition, they also provide good ventilation, and are relatively easy to maintain and clean.
[0003] At present, the running tracks at the upper and lower ends of the sliding window are mostly exposed to the outside. When installing the sash, the worker needs to fix the sash on the frame by the way of butting the rollers on the sash to the sliding rails, so that the sash can slide. However, in this way, since the rollers need to be directly butted to the sliding rails, there is a height difference between the bottom of the sash and the installation end face, resulting in a gap between the sash and the connection end face, so that external wind or rainwater can enter the indoor through the gap, and the air tightness and water tightness are low. In addition, due to the existence of the gap, the connection between the sash and the installation end face is not tight enough, and when the sash needs to move on the sliding rail, it is easy to shake, thereby reducing the air tightness and tightness of the sliding window.
