High-leakproofness sliding door and window

Abstract

The invention discloses a high-leakproofness sliding door and window. The high-leakproofness sliding door and window comprises a window frame and a sash. The sash is provided with a switching device, a transmission device and sealing devices. The upper position and the lower position of the window frame are provided with sliding groove parts, and the upper position and the lower position of the sash are provided with transverse rod pieces respectively. The sealing devices are arranged in the transverse rod pieces of the sash, the switching device drives the sealing devices to move up and down between a sealed position and an unlocked position through the transmission device. Bosses are arranged on the sliding groove parts of the window frame, grooves are formed in the transverse rod pieces, the bosses penetrate into the grooves, the transverse rod pieces of the sash are further provided with transverse protrusions, and the sealing devices can be combined with the transverse protrusions and the bosses in a sealed mode when reaching the unlocked position. According to the high-leakproofness sliding door and window, the gap between the sash and the window can be sealed through the movable sealing devices, the sealing performance of the sash is improved, the application range of the sliding door and window is expanded, production cost is low, and popularization is easy.

Description

technical field [0001] The invention relates to a sliding window, in particular to a high sealing sliding door and window. Background technique [0002] Sliding doors and windows are widely used because they are transparent and bright and do not take up space. However, at present, the sliding doors and windows of various domestic manufacturers are basically double sliding doors and windows sealed with tops, and their watertightness and airtightness are relatively low. With the continuous improvement of people's living standards and the continuous advancement of construction technology, transparent and bright sliding doors and windows are gradually being used in island resort hotels and high-rise buildings in coastal areas. The use of top-sealed sliding doors and windows for windy and rainy coastal areas can no longer meet the requirements, so it is necessary to provide a sliding door and window with high watertightness and airtightness to meet the needs of the market.

AI Technical Summary

Problems solved by technology

However, since the sealing strip only contacts and seals with the window frame by means of wool strips or rubber strips arranged on it, there is still a gap between the sealing strip and the sash so that it cannot be completely sealed, which affects the overall sealing performance of sliding doors and windows.

On the other hand, in order to improve the sealing performance of the sealing device relative to the window sash, the sealing strip must be installed close to the inner wall of the window sash, which increases the movement resistance of the sealing device, which not only increases the wear of the sealing strip itself but also reduces the customer experience
