Description

Technical Field

[0001] The invention belongs to the technical field of sliding windows, and in particular relates to an airway sealed sliding door and window. Background Art

[0002] Sliding windows are widely used in the construction field because of their beautiful appearance, convenient opening and closing, and small indoor space. Sealing strips need to be set between the sashes of the sliding window and between the sashes and the window frames to prevent indoor heat or cold air from leaking.

[0003] There are also many kinds of sliding doors and windows disclosed in the prior art. For example, patent CN201953257U discloses a sealed sliding window, including a window frame, a bright window and a window sash. The window frame is composed of an edge seal, an upper slide rail frame and a lower slide rail frame. The window sash is arranged between the upper slide rail frame and the lower slide rail frame, and is placed on the slide rail of the lower slide rail frame through a roller assembly. The upper slide rail frame has a sealing strip groove on the inner side facing the two upper window sash frames, and each upper window sash frame has two sealing strip grooves on the top side facing the bottom of the upper slide rail frame. The upper window sash frame has a sealing strip groove on the inner side facing the upper slide rail frame convex plate; the lower slide rail frame has a sealing strip groove on the inner side facing the two lower window sash frames; the window sash frame has a window sash frame flange, the window sash frame flange is inserted into the groove corresponding to the edge seal, and the groove has three sealing strip grooves; the hook frame has two sealing strip grooves; the lower window sash frame has a sealing strip groove on the two inner side surfaces facing the slide rail; the two side surfaces of the slide rail have a convex rib, and the convex rib corresponds to the sealing strip groove on the inner side of the lower window sash frame. The sealed sliding window disclosed in the patent can improve the sealing performance of the sliding window while solving the problem that the sealing strip on the lower window sash frame and the lower slide rail frame are frozen together in cold climates.

[0004] It is undeniable that the sealed sliding window disclosed in the patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: the roller assembly and the sealing strip groove in the lower window sash frame are in the same cavity, which may affect the installation of the roller assembly; in addition, the sealing between the lower window sash frame and the lower rail frame mainly relies on the sealing strip installed in the sealing strip groove on the inner side of the lower rail frame toward the lower window sash frame and the sealing strip installed in the sealing strip grooves on both inner sides of the lower window sash frame, and the sealing effect is limited.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.
