A window switching hinge including a slide way 1, a slide block 2, a push-pull rod 3, a tie rod 4 and a short rod 5 connected in a flexible manner. The short rod 5 has a plane salient 51 that glides with the slide way 1, and has a fixed angle with the slide way flank 11. The slide way 1 has a block stop 6 located in the sliding end which engages with the slide block when the window is closed. The block stop 6 has an inclined plane 61. The flank 11 of the slide way 1 has a notch 12 that allows the plane salient 51 to exit the slide way 1 when the short rod 5 is moved. To open the window the short rod 5 will slide along the plane salient 51 and run along the flank 11 of the slide way 1, while the push-pull rod 3 drives the slide block 2. To close the window, the push-pull rod 3 will pull the slide block 6 and short rod 5, and after the slide block 2 hits the block stop 6, the plane salient 51 in the short rod 5 will turn and fold along with the inclined plane 61 of the block stop 6. |
