AI Technical Summary
The existing casement window lifting blocks are difficult to close when the sash is sagging with a large swathe or the roller cannot rotate.
Design a casement window active lifting block including an upper buckle block and a lower buckle block. The surface of the upper buckle block is equipped with a raised side wall and a latch, and the surface of the lower buckle block is equipped with a gradually descending ladder oblique buckle plate, through the roller Surface movement enables automatic correction.
Through the coordinated connection between the upper buckle block and the lower buckle block, the window sash moves along the oblique edge of the ladder on the surface of the roller, and automatically corrects the position of the window sash and the window frame, solving the problem of poor sash closing effect, which is simple in structure and convenient in operation.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of doors and windows, and in particular to an active lifting block for a casement window. Background Art
[0002] The lifting block of the casement window is used to automatically lift the drooping window sash. The existing lifting block is installed in the window frame. A roller is provided in the lifting block. When the window sash is closed, the drooping window sash will move along the surface of the roller so as to automatically lift and assist in closing. However, if the window sash droops too much or the roller cannot rotate, the bottom of the window sash will conflict with the roller, making it difficult to close the window sash. Utility Model Content
[0003] The utility model solves the problem that the closing effect of the existing casement window lifting block and the window sash is poor.
[0004] The technical solution adopted by the utility model is: an active lifting block of a casement window, comprising an upper buckle block and a lower buckle block, the surface of the upper buckle block is relatively provided with raised side walls, a latch is provided between the two side walls, a roller is sleeved on the outer side of the latch, and the surface of the lower buckle block is provided with a raised buckle plate, the open end of the buckle plate gradually descends outward to form a ladder bevel, and the ladder bevel moves along the surface of the roller.
[0005] Compared with the prior art, the utility model has the following beneficial effects: in the casement window, the upper buckle block and the lower buckle block are matched and connected, so that the drooping window sash moves along the ladder bevel of the lower buckle block on the roller surface to play an automatic correction role, and the structure is simple and the operation is convenient.

[0010] like Figures 1 to 3The present invention discloses an active lifting block for a casement window, comprising an upper buckle block 10 and a lower buckle block 20. The upper buckle block 10 has raised side walls 11 on its surface, a latch 12 is arranged between the two side walls 11, a roller 13 is sleeved on the outer side of the latch 12, and a raised buckle plate 21 is arranged on the surface of the lower buckle block 20. The open end of the buckle plate 21 gradually descends outward to form a ladder bevel 22, and the ladder bevel 22 moves along the surface of the roller.
[0011] During specific implementation, the upper buckle block 10 is fixed to the window frame by fixing screws, and the lower buckle block 20 is fixed to the window sash by fixing screws. The window sash will sag after being opened and closed for a long time, resulting in obstruction in closing the window sash. The window sash moves along the roller 13 of the upper buckle block 20 through the buckle plate 21 end of the lower buckle block 20 and falls into the buckle plate 21, thereby actively correcting the window sash and the window frame.
[0012] In summary, the practical active lifting block of the casement window is connected by the upper buckle block 10 and the lower buckle block 20 in the casement window, so that the drooping window sash moves along the ladder bevel 22 of the lower buckle block 20 on the surface of the roller 13 to play an automatic correction role. The structure is simple and the operation is convenient.
