Of the invention exempts from digging formula shutting window device in use, and when sash needs to open, external force is on sash, window
Fan drives 20 common rotation of kerve component by connecting rod 206, while connecting rod 206 acts on positioning support arm 6, positions support arm
6 drive movable arms 7 again；Movable arms 7 drive the gear support arm 3 that is attached thereto to rotate, gear support arm 3 by with guide rail rack
2 cooperation drives guide rail rack 2 mobile.Guide rail rack 2 is gradually mobile to 44 side of spring in sash opening process, so that
The active force of guide rail rack 2 passes through the transmitting of mandril 41 and gasket 42, so that spring 44 is gradually compressed.By being equipped with spring 44
The opening speed of sash can be buffered.When sash is opened to required angle, rubbed by the first friction plate 30 and second
The frictional resistance of pad 40 acts on, so that positioning support arm 6 is located in the corresponding position of first sliding groove 71, effectively prevents positioning branch
The sliding of arm 6 realizes the positioned at arbitrary angles within the scope of opening angle so that sash is maintained at corresponding angle.External force
It can continue to push sash, so that positioning support arm 6 is slided along 21 direction of first sliding groove, the space of unlatching can be increased, it is full
Sufficient requirement.
Of the invention exempts from digging formula shutting window device in use, and when sash needs to close, compressed spring 44 rebounds,
Bounce is transferred to guide rail rack 2 by mandril 41, pushes guide rail rack 2 mobile, and guide rail rack 2 is rotated with moving gear support arm 3,
Then it drives movable arms 7 and positioning support arm 6 to rotate, realizes and drive kerve component 20 and rotation, realize the pass of sash
It closes.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection scope.
