Screen window linkage block structure

Abstract

A screen window linkage block structure includes at least one linkage block, which is used in conjunction with a screen window and a window. The screen window and the window move between a track. The linkage block has a first flange and a second flange protruding from its side, and a linkage flange protruding from its front. The screen window has a screen window frame with a longitudinally penetrating groove. The first flange and the second flange are engaged on both sides of the groove. The linkage block is installed on the screen window frame and can move longitudinally. The window is fixed with at least one linkage seat, and the linkage seat has a protruding push flange. The linkage flange can be positioned to block the push flange. When the window or the screen window moves, the window and the screen window can move together because the linkage flange and the push flange are mutually blocked. The height of the linkage block can be adjusted so that the linkage flange does not block the push flange, allowing the window or the screen window to move freely.

Claims

1. A screen window linkage block structure, comprising at least one linkage block, said linkage block being used in conjunction with a screen window and a window, said screen window and window being movable between a track, wherein: The linkage block has a first flange and a second flange protruding from its side. The first flange has a first locking flange protruding forward, and a first locking opening is formed on the inner side of the first locking flange. The second flange has a second locking flange protruding backward, and a second locking opening is formed on the inner side of the second locking flange. The linkage block has a linkage flange protruding from its front. The screen window has a screen window frame with a longitudinally penetrating groove. A first slot and a second slot are respectively recessed on both sides of the groove. A first locking part and a second locking part are respectively protruding inward from the edges of the first slot and the second slot. The second locking edge is inserted into the second slot, causing the second locking part to be inserted into the second locking opening. When force is applied to the linkage block, the first locking part pushes against the first flange, causing it to elastically retract. After the first flange elastically returns to its original position, the first locking edge is inserted into the first slot, causing the first locking part to be inserted into the first locking opening. Thus, the linkage block is installed on the screen window frame and can move longitudinally. The window is fixed with at least one linkage seat, and the linkage seat is provided with a push flange. The linkage flange can be located at a position that blocks the push flange. When the window or the screen moves, the linkage flange and the push flange can push against each other because they are blocked by each other, so that the window and the screen move together. The linkage block can slide longitudinally along the screen frame to adjust its height, so that the linkage flange does not block the push flange and the window or the screen moves freely without interfering with each other.

2. The screen window linkage block structure as described in claim 1, wherein, The second locking edge is arc-shaped and has an elastic hole running through it.

3. The screen window linkage block structure as described in claim 1 or 2, wherein, There are two linkage blocks and two linkage seats, which are located at the top and bottom ends of the window.

4. The screen window linkage block structure as described in claim 1 or 2, wherein, A dustproof strip is fixed on the linkage seat to contact the surface of the screen.

5. The screen window linkage block structure as described in claim 4, wherein, The linkage seat is provided with a fixed seat, which has a fixed opening facing upward. The dustproof strip is inserted into the fixed opening from top to bottom and protrudes from the surface of the fixed seat to contact the surface of the screen.

6. The screen window linkage block structure as described in claim 4, wherein, The dustproof strip is adhesively fixed to the linkage seat.

7. The screen window linkage block structure as described in claim 1 or 2, wherein, The linkage seat is fixed to the window by a set of screw fasteners.
