Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figures 1 to 7 , an embodiment provided by the utility model:

[0029] A wind-resistant sliding window comprises a horizontally arranged window frame guide rail and two slide grooves 1 spaced apart from each other on the window frame guide rail. An outer sash window 2 and an inner sash window 3 are slidably connected to the two slide grooves 1. The outer sash window 2 and the inner sash window 3 are respectively provided with outer columns 4 and inner columns 5 that can be staggered and overlapped. A column gap 6 is defined between the outer columns 4 and the inner columns 5, and a sealing mechanism is provided that movably seals the column gap 6.

[0030] The sealing mechanism includes a driving plate 7 provided on the outer column 4, and a driving groove 8 provided on the inner column 5. The driving plate 7 extends toward the inner column 5 and is movably inserted into the driving groove 8. The inner column 5 is provided with a transmission component that is transmission-connected to the driving plate 7, and a sealing strip 9 that is movably retractable toward the outer column 4. One end of the transmission component is movably retractable in the driving groove 8, and the other end of the transmission component is transmission-connected to the sealing strip 9. One end of the sealing strip 9 is slidingly connected to the inner column 5, and the other end of the sealing strip 9 is movably abutted against the outer column 4.

[0031] The window frame rails are horizontally arranged, while the window frame baffles are vertically arranged. The rails and baffles are connected to form a U-shaped structure, which is used to mount the outer sash window 2 and the inner sash window 3. Two chute grooves 1 are located on the window frame rails, distributed along the rails, and spaced apart. Two baffle grooves 19 are located on the window frame baffles, distributed along the baffles, and connected to the chute grooves 1 one by one. The outer sash window 2 and the inner sash window 3 are respectively installed in the chute grooves 1 and slidably connected to the chute grooves 1. When the outer sash window 2 and the inner sash window 3 slide to the end of the chute groove 1, the outer sash window 2 and the inner sash window 3 are inserted into the baffle grooves 19. The outer column 4 is located to the right of the outer sash window 2, and the inner column 5 is located to the left of the inner sash window 3. The relative sliding of the outer sash window 2 and the inner sash window 3 allows the outer column 4 and the inner column 5 to move closer or further away from each other. The outer sash window 2 and the inner sash window 3 are spaced apart, forming a column gap 6 between the outer column 4 and the inner column 5. When the sliding window needs to be closed, the outer sash window 2 and the inner sash window 3 slide relative to each other, and the outer columns 4 and the inner columns 5 approach each other until the outer columns 4 and the inner columns 5 overlap, driving the sealing mechanism to close the column gap 6.

[0032] The drive plate 7 is located on the outside of the outer column 4, extending toward the inner column 5, protruding from the surface of the outer column 4, and is used to trigger the transmission assembly. The drive slot 8 is located on the outside of the inner column 5, matching the shape and corresponding to the position of the drive plate 7. When the outer column 4 and the inner column 5 are close to each other, the drive plate 7 is inserted into the drive slot 8. The transmission assembly is located inside the inner column 5, and is arranged in an L-shaped distribution. It can be a connecting rod transmission structure that converts left and right movement into forward and backward movement. The sealing strip 9 is movable and retractable inside the inner column 5, extending toward the outer column 4, and is installed vertically. The sealing strip 9 is made of elastic rubber material, and is equal in length to the outer column 4 and the inner column 5, and can close the column gap 6 between the outer column 4 and the inner column 5.

[0033] One end of the transmission assembly is movably retractable within the drive slot 8 and is slidably connected to the drive slot 8 in a horizontal sliding direction. The other end of the transmission assembly is transmission-connected to a sealing strip 9 and is slidably connected to the inner column 5 in a forward-backward sliding direction.

It can be understood that one end of the transmission assembly is a free end, and the other end of the transmission assembly is a connecting end. The free end extends from the drive slot 8 and is connected to the sealing strip 9. When the sliding window needs to be closed, the outer sash window 2 and the inner sash window 3 slide relative to each other until the outer column 4 and the inner column 5 overlap. At this time, the drive plate 7 is inserted into the drive slot 8 and pushes the free end into the interior of the inner column 5. The transmission assembly converts the left-right movement of the free end into the forward-backward movement of the connecting end, driving the sealing strip 9 to slide relative to the inner column 5 and extend toward the outer column 4 until the sealing strip 9 abuts against the outer column 4, thereby sealing the column gap 6.

[0034] The present invention provides a sealing mechanism. When the sliding window needs to be closed, the outer sash 2 and the inner sash 3 slide relative to each other until the outer pillar 4 and the inner pillar 5 overlap. During this period, the driving plate 7 is inserted into the driving groove 8, the driving plate 7 abuts the transmission assembly, and then pushes the transmission assembly. The transmission assembly is connected to the sealing strip 9, and then drives the sealing strip 9 to slide relative to the inner pillar 5. The sealing strip 9 extends toward the outer pillar 4 until the sealing strip 9 abuts against the outer pillar 4, realizing the active sealing of the gap 6 between the pillars by the sealing mechanism, effectively improving the sealing between the two window sashes and preventing the window sashes from colliding and air leakage through the gaps.
