Preferably, the first fixing lever is connected to the window frame 1 by a first bolt, and the second fixing lever 42 is connected to the window sash 2 by a second bolt. The first parallelogram link portion 3 and the second parallelogram link portion 4 are easily detached by the user.
On the basis of the above-mentioned embodiment, the bending lever 32 is provided with a stopper for restricting the rotation of the second link 41.
It should be noted that, when the second connecting rod 41 rotates to the limiting position, the second connecting rod 41 will contact with the limiting block on the bending rod 32 and be blocked by the limiting block, the second connecting rod 41 will maintain the existing angle shape, and the bending rod 32 will be rotated outward by the acting force transmitted from the second connecting rod 41 through the limiting block, so that the second connecting rod 41 and the bending rod 32 can be rotated and unfolded successively, and the user can select the required opening size of the window sash 2 and open the second connecting rod 41 and the first connecting rod in stages, so as to avoid the interference between the first connecting rod and the second connecting rod 41 during rotation. The pretension adjusting part can be a bolt, a torsion spring and other parts, the user changes the acting force required by the user to rotate the first connecting rod by adjusting the pretension of the pretension adjusting part on the first connecting rod, and similarly, the pretension adjusting part used for adjusting the acting force required by the rotation of the second connecting rod 41 is also arranged on the first ejector rod 31, the pretension force on the first connecting rod can be set to be smaller than that of the second connecting rod 41, when the window sash 2 is pushed and pulled, the window sash 2 can rotate around the first ejector rod 31 firstly, when the second connecting rod 41 rotates to the position of the limiting block, the first parallelogram connecting rod part 3 starts to move around the hinge point of the first parallelogram connecting rod part 3 and the window frame 1 until the window sash 2 is completely opened.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The casement window provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
