Detailed Description

The window opening and closing apparatus according to the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

The present embodiment provides a window opening and closing apparatus for adjusting the opening degree of a window sash 100 with respect to a wall 200. Referring to fig. 1 and 2, fig. 1 is a front view of a window opening and closing apparatus of the present invention, fig. 2 is a plan view of the window opening and closing apparatus of the present invention, the window sash 100 is hinged with the wall 200, the window opening and closing device comprises a first high-altitude connecting rod 310, a second high-altitude connecting rod 320 and a high-low connecting longitudinal rod 330, the window sash 100 is hinged to the first high-altitude link 310, the first high-altitude link 310 is hinged to the second high-altitude link 320, the second high-altitude connecting rod 320 is fixedly connected with one side of the high-low connecting longitudinal rod 330, the high-low connecting longitudinal rod 330 is rotatably connected to the wall 200, the window sash 100, the first high-altitude connecting rod 310 and the second high-altitude connecting rod 320 form a four-bar mechanism, the plane of the four-bar mechanism is perpendicular to the high-low connecting longitudinal bar 330, and the other side of the high-low connecting longitudinal bar 330 is far away from the window sash.

Since the high-low connecting longitudinal rod 330 is rotatably connected to the wall 200, and the second high-altitude connecting rod 320 is fixedly connected to one side of the high-low connecting longitudinal rod 330, the second high-altitude connecting rod 320 can be driven to rotate by driving the high-low connecting longitudinal rod 330 to rotate. Because the wall 200, the window sash 100, the first high-altitude connecting rod 310 and the second high-altitude connecting rod 320 form a four-bar mechanism, and the plane of the four-bar mechanism is perpendicular to the high-low connecting longitudinal rod 330, the window sash 100 can be driven to rotate relative to the wall 200 by the second high-altitude connecting rod 320, and the opening degree of the window sash 100 relative to the wall 200 can be adjusted. Because the other side of the high-low connecting longitudinal rod 330 is far away from the window sash, the other side of the high-low connecting longitudinal rod 330 can be rotated to drive the second high-altitude connecting rod 320 fixedly connected with one side of the high-low connecting longitudinal rod 330 to rotate, so as to drive the window sash 100 to rotate, and particularly when the other side of the window sash which is positioned at the high position and is connected with the longitudinal rod 330 at the high position is close to the ground relative to the window sash, an operator can conveniently adjust the opening degree of the window sash 100 relative to the wall body 200 on the ground.
