Description

Technical Field

[0001] The utility model relates to the technical field of sliding windows, and more specifically to a sliding window with high sealing performance. Background Art

[0002] In the current market, the opening and closing modes of windows are basically divided into casement windows and sliding windows. The materials are mainly divided into three categories: plastic steel, aluminum alloy and thermally insulated aluminum. The advantage of casement windows is good sealing, but the disadvantage is that the opening and closing of windows takes up indoor and outdoor space, and the opening size is not easy to control. Especially when opening windows in windy weather, it is easy to cause the windows to open and close repeatedly with the wind, causing damage. The advantage of sliding windows is that they save space, the opening size is easy to control, and the window opening size will not change even in windy weather. The disadvantage is poor sealing.

[0003] The improvement of the sealing of sliding windows in the market now is mainly to increase the sealing strips at the guide rails, and the sealing strips between the window frame and the window sash. The disadvantage of this method is that it will increase the resistance of the window sash opening and closing, and due to long-term repeated friction, it will reduce the life of the sealing strips and reduce the sealing. Moreover, the sealing of this method is still poor compared with the sealing of the casement window compression type. Recently, a window that can be pushed and pulled and closed by compression has appeared on the market, but due to the limitation of its push-pull principle, this type of window has high requirements for materials and hinge strength, resulting in a high overall cost of the window, which is a heavy burden for ordinary consumers. In addition, due to its push-pull principle, the durability of its hinge part is poor.

[0004] The previously applied patent 202322468754.7 discloses a low-cost and highly sealed sliding window. Although the sealing performance of the sliding window is achieved in this application, the guide rail groove of the sliding window in this application is relatively wide. Although the window sash is positioned with spring clips, the guide rail groove is relatively wide and it is difficult to ensure the stability of the window sash. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a sliding window with high sealing performance, which adopts a compression sealing method to improve the sealing performance and stability of the window sash.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] A sliding window with high sealing performance, combined with Figures 1 to 10 As shown, it includes a fixed window frame 1 and a movable window sash 3, wherein the fixed window frame 1 is arranged on the window of the house, and the movable window sash 3 is slidably arranged on the fixed window frame 1, and glass 7 is arranged on both the fixed window frame 1 and the movable window sash 3. A guide rail 2 is arranged at the bottom end of the fixed window frame 1, and a guide rail groove is arranged at the bottom end of the movable window sash 3, and the guide rail groove cooperates with the guide rail to facilitate the movable window sash to move left and right on the guide rail. A plurality of rollers 5 are arranged at the top end of the guide rail groove, and the rollers 5 are perpendicular to the direction of the guide rail to facilitate the movable window sash to move along the guide rail.

[0028] A fixed window sash 6 is arranged on the outer side of the guide rail 2 at the closed position of the movable window sash 3, and a sealing strip 4 is arranged inside the fixed window sash 6 via a sealing strip support structure 8, so as to improve the sealing performance between the movable window sash 3 and the fixed window sash 6 when the movable window sash 3 is closed.

[0029] The fixed window sash 6 is provided with a pressing structure, which is matched with the sealing strip supporting structure 8 to seal the movable window sash with the fixed window sash when the movable window sash is closed.

[0030] The clamping mechanism includes pulleys 12 arranged at the four corners of the fixed window sash 6 and a handle 10 arranged on the fixed window sash 6. A steel wire 11 is sleeved on the pulley, and the steel wire 11 is connected to the handle. A plurality of sliders 9 are arranged on the steel wire 11. A groove 13 matching the slider 9 is opened on the sealing strip support structure 8. The steel wire can rotate forward and reversely around the pulley following the handle. The forward rotation of the handle drives the steel wire to rotate clockwise, and the reverse rotation of the handle drives the steel wire to rotate counterclockwise.

[0031] A sliding groove is provided on the inner side of the fixed window sash 6 for allowing the sealing strip 4 to move forward and backward. One end face of the sealing strip supporting structure 8 is connected to the sealing strip 4, and the other end face of the sealing strip supporting structure 8 is abutted against the slider 9 on the clamping structure. The sealing strip supporting structure moves forward and backward according to the position of the slider, thereby pushing the sealing strip to move forward and backward, thereby achieving sealing between the movable window sash and the fixed window sash.

[0032] The sealing strip support structure 8 can also be embedded in the inside of the sealing strip. The end face of one side where the sealing strip and the sealing strip support structure are embedded is in contact with the slider 9 on the clamping mechanism. A groove 13 matching the slider is provided on the side of the sealing strip that is in contact with the slider, which pushes the sealing strip to move forward and backward to achieve sealing between the movable window sash and the fixed window sash.

[0033] The inner side of the slider 9 is a trapezoidal convex structure, and the groove 13 is a concave trapezoidal structure. The two are matched to provide a smooth and slow slope to buffer the force of the slider movement.

[0034] The utility model discloses that when the movable window sash is closed, it moves left and right through the track to the fixed window sash, and the handle is rotated downward. The handle rotates forward, and the steel wire drives the sliding block to move out of the groove on the sealing strip supporting structure. The sealing strip supporting structure pushes the sealing strip forward to compress and seal the movable window sash, thereby improving the sealing performance of the movable window sash.

[0035] When releasing, rotate the handle upward and reverse it, and the steel wire drives the slider to move into the groove on the sealing strip support structure. The sealing strip support structure releases the sealing strip, and the sealing strip moves backward and no longer presses the moving window sash. At this time, the moving window sash can be moved left and right.
