Referring to fig. 2 to 4, an embodiment of the present application provides an inverted sliding window sliding apparatus 10, including: slide base 101, slide bar 102, positioning base 11, supporting base 103 and swing arm 104. Wherein the sliding seat 101 is configured to be disposed in a track (not shown) of the window frame and capable of sliding along a first direction (shown in an X direction in fig. 2) relative to the track; the sliding bar 102 is connected to the sliding base 101 by a sliding shaft 108, the sliding shaft 108 being capable of sliding relative to the sliding base 101 in a first direction, the sliding bar 102 being capable of rotating about the sliding shaft 108, the sliding bar 102 comprising a first end 1020 of the sliding bar and a second end 1021 of the sliding bar in the first direction.

Illustratively, the upper surface of the slider 102 in the second direction (shown in the Z-direction in fig. 3) has a lowest point, i.e., the upper surface of the slider 102 has a set slope. The support base 103 is for connection with a window sash. One end of a swing arm 104 is positioned in the sliding seat 101 and is rotationally connected with the sliding seat 101, and the other end of the swing arm 104 is positioned outside the sliding seat 101 and is rotationally connected with the supporting seat 103, namely, the swing arm 104 connects the window sash with the window frame through the sliding seat 101 and the supporting seat 103. Illustratively, the connection of the swing arm 104 to the sliding seat 101 is achieved through a shaft 1043 and a bearing 1044, the swing arm 104 being rotatable about the shaft 1043, the bearing 1044 being capable of reducing rotational friction during rotation of the swing arm 104.

The swing arm 104 of the present embodiment is capable of switching between a first state (shown in fig. 4) and a second state (shown in fig. 2); in the first state, the supporting seat 103 is located above the sliding seat 101, the swing arm 104 is located on the side surface of the sliding seat 101 and is close to the sliding seat 101, the second end 1021 of the sliding bar is clamped with the positioning seat 11, and the first end 1020 of the sliding bar is separated from one end of the swing arm 104. Referring to fig. 2 and 5, in the second state, the swing arm 104 is far away from the side of the sliding seat 101 and rotates relative to the sliding seat 101, the first end 1020 of the sliding bar is clamped with one end of the swing arm 104, and the second end 1021 of the sliding bar is separated from the positioning seat 11.

With the above technical solution, referring to fig. 1 and 6, when the handle 1 is in the horizontal position, by pulling the handle 1 outwards, i.e. in a third direction (Y direction in fig. 1) and towards the body part of the user, the sash 26 can be opened while remaining parallel to the window frame 27, i.e. the sash 26 is disengaged from the window frame 27, and when the sash 26 is opened to a maximum state in the third direction and parallel to the window frame 27, i.e. the state shown in fig. 6 and 7. Referring to fig. 2 to 5, the swing arm 104 is switched from the first state to the second state, that is, the second end 1021 of the sliding bar is separated from the positioning seat 11, the first end 1020 of the sliding bar is clamped with one end of the swing arm 104, the swing arm 104 is far away from the side surface of the sliding seat 101 and rotates relative to the sliding seat 101, and the limiting function of the maximum opening state of the window sash 26 in the third direction is realized. Referring to fig. 1 and 2, pulling the handle 1 in a first direction (shown in X direction in fig. 1), the window sash may perform a translational (push-pull) motion along with the sliding of the sliding seat 101 in the track, i.e., when the window sash is in a translational state, and when the window sash continuously translates and is opened to a maximum state, the window sash performs synchronous braking and impact buffering of the limit position with the upper and lower anti-collision blocks 24 and 25 in the first direction, i.e., when the window sash is buffered and stopped moving by collision with the upper and lower anti-collision blocks 24 and 25.

Referring to fig. 1 and 4, when the handle 1 is pulled in the opposite direction, i.e. in the first direction (indicated by the X direction in fig. 1) and towards the positioning seat 11, the sliding seat 101 slides along with it in the track, as well as the sash. When the sliding bar 102 is impacted by the positioning seat 11, the sliding shaft 108 slides relative to the sliding seat 101 along the first direction, and in the process that the sliding bar 102 is impacted by the positioning seat 11, the first end 1020 of the sliding bar is separated from one end of the swing arm 104, the swing arm 104 starts to rotate and gradually approaches the sliding seat 101, and at the moment, the sliding shaft 108 rotates relative to the sliding seat 101, and the second end 1021 of the sliding bar is pressed down and buckled into the positioning seat 11 to be clamped with the positioning seat 11; the latch fan upper piece 23 cooperates with the latch frame upper piece 22 to realize a self-locking function. At this time, when the window sash is in a closed state and the handle 1 rotates downwards by 90 ° (the handle is downwards), the driver 2 realizes the transmission of a certain stroke under the linkage action of the handle 1, the driver 2 further drives the plurality of C-groove transmission rods 3 to transmit, at this time, the turning rod 4 is matched with the anti-falling device 5, the locking rod 12 is matched with the lock seat 13, and the corner device B14 and the corner device a21 are matched with the lock seat 13 to jointly realize the complete locking function of the window sash 26 and the window frame 27, namely as shown in fig. 8.

In some possible embodiments, referring to fig. 3 to 5, the first end 1020 of the sliding bar is elastically connected to the sliding seat 101, so that when the sliding seat 101 impacts the positioning seat 11 along the first direction (shown in the X direction in fig. 4), the first end 1020 of the sliding bar is separated from one end of the swing arm 104, and the second end 1021 of the sliding bar is clamped with the positioning seat 11. That is, when the sliding seat 101 impacts the positioning seat 11 along the first direction, the sliding bar 102 slides in the opposite direction to the impact direction, so that the first end 1020 of the sliding bar is separated from the end of the swing arm 104, and the second end 1021 of the sliding bar is further clamped with the positioning seat 11, so as to realize the locking function of the swing arm 104 in the first state, and further avoid the window sash from moving.
