Background technique

Sliding window is a kind of window widely recognized at present. The sashes installed in the window frame can slide along the corresponding guide rails; when one of the sashes needs to be opened, just slide the sashes to the other direction. For sliding windows, the lower rail is one of the main profiles of sliding windows, and its importance is prominent in sliding window profiles, supporting the inner and outer sash. The lower rail and the window sash are mostly equipped with sealing strips with sealing tops. The tops play the role of sound insulation, dustproof, antifreeze, and heat preservation. However, if the top specification is too large or the vertical wool is too high, it will not only increase the difficulty of assembly, but also increase the movement resistance of the sash, especially the initial resistance when opening and the final resistance when closing. If the specification is too small, or the height of the vertical wool strip is not enough, it is easy to fall out of the groove, which greatly reduces the sealing performance of the sliding window.
