OPENING DEVICE USED IN SLIDING WINDOW AND SLIDING WINDOW

摘要

An opening device used in sliding windows and a sliding window. The opening device comprises: a base (3), a rotating axle (4), a guide cable (2), a fastener, a threaded shaft (7), a threaded shaft nut (8), an orienting component, a first friction component (5), a second friction component (6), and a flexible component. The rotating axle (4) is installed on the base (3). The guide cable (2) is wound around the rotating axle (4). The fastener is installed between the base (3) and the rotating axle (4). The threaded shaft (7) rotates with the rotating axle (4). The threaded shaft nut (8) engages with the threaded shaft (7). The orienting component is installed on the base (3) and restricts a rotation of the threaded shaft nut (8). The first friction component (5) is sleevingly installed on the threaded shaft (7), and moves, with the rotation of the threaded shaft (7), axially along the threaded shaft (7). The second friction component (6) is fixedly installed on the base (3) and forms a frictional engagement with the first friction component (5). The flexible component is installed between the first frictional component (5) and the threaded shaft nut (8). When the rotating axle (4) rotates along a first direction, the guide cable (2) unwinds from the rotating axle (4) and the threaded axle nut (8) moves towards the side of the second frictional component (6) to press against the first frictional component (5), thereby increasing a frictional force between the first frictional component (5) and the second frictional component (6).
