[0001] The invention relates to the field of aluminum alloy doors and windows, and in particular to a side-sliding aluminum alloy sliding window. Background Art

[0002] Aluminum alloy sliding windows are common building windows. The pulley of existing aluminum alloy sliding windows is set at the bottom of the window sash, and the bottom of the window frame is correspondingly provided with a slide rail for the pulley to slide. The above structure causes the height of the bottom frame to be relatively large, which cannot meet the needs of some extremely narrow frame sliding windows. In addition, some high-end sliding windows provide an automatic closing function, which adopts a structure similar to an automatically closing drawer, and uses a spring to drive the mechanical energy stored when the window is opened to drive the door and window to automatically close when it approaches the closing point. However, since the window sash of aluminum alloy windows is heavier, it needs to store a large amount of energy, resulting in users needing a large force to open the window, resulting in a poor user experience.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0025] like Figure 1-Figure 6 As shown, a specific first embodiment of the present invention provides a side-sliding aluminum alloy sliding window, including a window sash 1 and a window frame 2, the inner side wall of the window frame 2 is provided with a supporting plate 21 extending toward each other, and the supporting plate 21 is provided with a first slide rail 22 and a second slide rail 23; the side of the window sash 1 is provided with a first pulley 11 and a second pulley 12, the first pulley 11 is connected to the window sash 1 through a first rotating shaft 13 fixed on the side of the window sash 1, and the second pulley 12 is provided on the side of the window sash 1 through a pulley seat 14, and the second pulley 12 is slidably arranged in the pulley seat 14 and can move up and down along the pulley seat 14; the second slide rail 23 is provided with an arc-shaped recessed portion 24, and the second pulley 12 can be accommodated in the arc-shaped recessed portion 24.

[0026] With the above structure, the window sash 1 is supported on the window sash 1 by the first pulley 11 and the second pulley 12 located on the side, which can effectively reduce the height of the window frame 2 and meet the requirements of the extremely narrow frame aluminum alloy window. The window sash 1 is supported by two sets of pulleys, so that the operation of the window sash 1 is more stable and the noise generated during movement is reduced. Among them, the first pulley 11 is a pulley with a fixed shaft position, which can ensure that the window sash 1 moves at the same height; the shaft of the second pulley 12 can move up and down, and it shares the load-bearing of the first pulley 11 at ordinary times, and uses its own buffering capacity to reduce the noise when the roller rotates. The second slide rail 23 is provided with an arc-shaped recessed portion 24. When the window sash 1 reaches the closed position, the second pulley 12 can be accommodated in the arc-shaped recessed portion 24 to achieve automatic closing and automatic locking of the window sash 1; the arc-shaped recessed portion 24 can correspond to pulleys at different positions, and evenly apply force to the bottom of the window sash 1 to ensure a smooth automatic closing process.

[0027] In order to achieve the cooperation between multiple groups of rollers at different positions and the arc-shaped recessed portion 24, a vertically extending receiving groove 241 is provided in the center of the arc-shaped recessed portion 24, and a lifting plate 25 is provided in the receiving groove 241. A first spring is provided at the bottom of the lifting plate 25, and the first spring is used to reset the lifting plate 25 after it is lowered. A locking groove 27 is provided at the inner side wall of the window frame 2 corresponding to the arc-shaped recessed portion 24, and a locking member 26 is provided in the locking groove 27. A second spring is provided at the bottom of the locking member 26, and the second spring is used to reset the locking member 26 after it is pressed down. The locking member 26 has a horizontally extending locking rod 262; the lifting plate 25 is provided with a locking hole 251, and the locking rod 262 can extend into the locking hole 251 to limit the lifting and lowering of the lifting plate 25. The locking member 26 is also provided with an unlocking press member 263, and the unlocking press member 263 is arranged above the locking rod 262; the side of the window sash 1 is correspondingly provided with an unlocking protrusion 15, and the unlocking protrusion 15 can press the unlocking press member 263 to push the locking member 26 to move to the bottom of the locking groove 27, and the locking rod 262 is disengaged from the locking hole 251.

[0028] Normally, the lifting plate 25 is fixed by the locking rod 262. When the second pulley 12 passes through the arc-shaped recessed portion 24, it will pass on the lifting plate 25 and will not fall into the arc-shaped recessed portion 24, thereby preventing the second pulley 12 from suddenly falling into the arc-shaped recessed portion 24 during the window opening process, causing abnormal noise and unnecessary vibration of the window sash 1. When the window sash 1 reaches a position close to being fully closed during the closing process, the unlocking protrusion 15 will push the corresponding unlocking pressing member 263, pushing the locking member 26 to move toward the bottom of the locking groove 27, and the locking rod 262 will be disengaged from the locking hole 251, so that the lifting plate 25 can be freely lifted and lowered; at this time, the second pulley 12 pushes the lifting plate 25 to press it down, and the second pulley 12 falls into the arc-shaped recessed portion 24 under the thrust of the third spring 16, thereby pushing the window sash 1 to be fully closed. When the window needs to be opened, only a force needs to be applied to open the window sash 1, and the second pulley 12 will disengage from the arc-shaped recessed portion 24. The lifting speed of the second pulley 12 gradually increases, so the initial resistance is small. When the user turns the stationary window sash 1 into a moving one, there is no need to face particularly large resistance, thereby optimizing the user's experience of opening and closing the window.

[0029] In order to prevent dust and other debris from clogging the arc-shaped recessed portion 24 , an escape notch 242 is provided at one end of the arc-shaped recessed portion 24 , and the escape notch 242 is lower than the arc-shaped recessed portion 24 .

[0030] Preferably, a plurality of the arc-shaped recessed portions 24 are disposed on the second slide rail 23 , and the unlocking pressing members 263 corresponding to different arc-shaped recessed portions 24 are disposed at different heights of the locking member 26 .

[0031] It should be noted that by arranging the unlocking pressing pieces 263 corresponding to different arc-shaped recessed portions 24 at different heights of the locking piece 26, it is possible to avoid the non-corresponding second pulley 12 from contacting the unlocking pressing piece 263 when passing through the arc-shaped recessed portion 24, thereby preventing unnecessary running resistance.

[0032] Preferably, the pulley seat 14 includes a transversely extending extension plate 141 and a pulley bin 142 extending downward from the end of the extension plate 141; a sliding groove 143 is provided in the pulley bin 142, a bearing 144 is provided in the sliding groove 143, and the second pulley 12 is connected to the bearing 144 via a second rotating shaft 145; the bearing 144 can slide up and down in the sliding groove 143, and a third spring 16 is provided between the bearing 144 and the pulley bin 142. In order to protect the first pulley 11, the pulley seat 14 can be arranged on the outside of the first pulley 11.

[0033] In order to ensure the smooth operation of the locking member 26 , the locking member 26 is “L”-shaped, including a horizontal locking member 264 and a vertical connecting member 261 , more than two locking rods 262 are arranged on the horizontal locking member 264 , and the unlocking pressing member 263 is arranged on the vertical connecting member 261 .

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
