Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and in particular relates to an inward opening window sash structure. Background Technology

[0002] Traditional inward-opening windows have a sash structure where the fastener is located on the interior side of the sash for easy glass installation, resulting in seams and lines on the interior surface. While concealed sash windows on the market achieve a seamless, integrated interior surface design, the external fastener design and widened single-arm wing design of the outer frame not only make the fixed window structure too wide but also increase material costs. With increasingly higher aesthetic demands, there is a need for an inward-opening window system with a minimalist, slim, and flat surface that facilitates glass installation and removal while maintaining a sleek and seamless interior appearance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an inward-opening window sash structure, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an inward-opening window sash structure, comprising a window sash, the window sash being mounted on the indoor half of a window frame, the window sash opening inwards, and a sash fastening strip mounted on the outdoor side of the window sash, characterized in that a locking block is fixedly mounted on the outdoor side of the window sash near the glass side, and the sash fastening strip is engaged with the corresponding groove on the locking block via protrusions thereon; further comprising a fastening assembly for fastening the locking block and the sash fastening strip.

[0005] Beneficial effects This utility model provides an inward-opening window sash structure, which has the following advantages compared with the prior art: With the window sash rotated to the indoor side, the locking block on it should be fully exposed to the installer's view. The user can then install the sash retaining strip onto the locking block, ensuring the retaining strip overlaps and fits snugly against the L-shaped edge of the locking block. Simultaneously, the user should screw the fastening screw into the retaining strip, ensuring the fastening bolt penetrates into the cavity of the locking block, thus mechanically fastening the retaining strip. At this time, the protrusions on the retaining strip simultaneously engage with the corresponding grooves on the locking block. A rubber strip is then inserted between the retaining strip and the locking block, and its position is secured by the protrusions on the retaining strip. When the window sash is closed, the retaining strip is pressed against the single-arm wing edge of the window frame, further limiting its position and increasing the stability of the window sash in the closed state, thus ensuring a stable connection of the glass within the window sash.
