[0024] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0025] Embodiment Since some existing window forms limit the opening angle of the window sash, users cannot lean out of the window, thus ensuring user safety. This design will sacrifice the ventilation area of the window form, resulting in poor indoor ventilation.

[0026] Therefore, the present application discloses a window with an adjustable window sash position. Referring to Figure 1 , this window includes a window frame 10, and a first window sash 20 is installed inside the window frame 10. Referring to Figure 3-4 , a first hinge 30 is installed on the window frame 10. The first hinge 30 includes a first fixed structure 31 and a first movable structure 32. Among them, the first fixed structure 31 is installed on the window frame 10, and the first movable structure 32 is respectively connected to the first window frame 10 and the first fixed structure 31, and the first movable structure 32 is used to control the movement of the first window sash 20 relative to the first fixed structure 31, thereby realizing the opening and closing of the first window sash 20 relative to the window frame 10.

[0027] Referring to Figure 6 and Figure 7 , this window with an adjustable window sash position further includes a limiting unit 40. The limiting unit 40 is installed on the window frame 10, and the limiting unit 40 is used to limit the rotation angle of the first movable structure 32. When the limiting unit 40 works, the first movable structure 32 can only rotate a small angle relative to the first fixed structure 31, and can only drive the first window sash 20 to rotate a small angle. At this time, the window with an adjustable window sash position ventilates in the first state as shown in Figure 3 . In this state, the window with an adjustable window sash position ensures user safety with a small ventilation area.

[0028] When the limiting unit 40 releases the limit, referring to Figure 11 or Figure 12 , at this time, the first movable structure 32 can rotate a large angle relative to the first fixed structure 31, so that the first window sash 20 can rotate a large angle relative to the window frame 10, and thus a large ventilation area can be obtained after the first window sash 20 rotates, resulting in good indoor ventilation effect. By setting the limiting unit 40, users can select the required usage state according to the usage scenario, so that the window with an adjustable window sash position can balance the safety and ventilation performance during use.

[0029] Specifically, referring to Figure 5 and Figure 6 , the first movable structure 32 includes a first mounting plate 311, and the first mounting plate 311 is fixed to the window frame 10. The first movable structure 32 includes a first mounting block 321, a second mounting block 322, a first rotating rod 323, a second rotating rod 324 and a second mounting plate 325. The first mounting block 321 is fixedly installed at one end of the first mounting plate 311, the second mounting block 322 is slidably connected to the first mounting plate 311, the second mounting plate 325 is arranged on one side of the first mounting plate 311, and the second mounting plate 325 is used for installing the first window sash 20. The two ends of the first rotating rod 323 are respectively rotatably connected to the first mounting block 321 and the second mounting plate 325, and the two ends of the second rotating rod 324 are respectively rotatably connected to the second mounting block 322 and the second mounting plate 325.

[0030] When the second mounting block 322 slides relative to the first mounting plate 311, the first rotating rod 323 and the second rotating rod 324 cooperate to rotate, so that the first window sash 20 installed on the second mounting plate 325 can open and close relative to the window frame 10.

[0031] Referring to Figure 6 , in an embodiment of the present invention, a chute is provided on the first mounting plate 311, and the second mounting block 322 is slidably connected in the chute.

[0032] Referring to Figure 6 , in an embodiment of the present invention, the limiting unit 40 is used to limit the sliding of the second mounting block 322 in the chute, so that the rotation angle of the second mounting plate 325 relative to the window frame 10 is smaller, so as to protect the user.

[0033] Referring to Figure 7-9 , the limiting unit 40 includes a first handle 41, a lever 42, a first driving rod 43, a second driving rod 44, a first tension member 45 and a first limiting pin 46 for limiting the first movable structure 32. Combining Figure 1 , the first handle 41 is rotatably connected to the window frame 10, the lever 42 is fixedly connected to the end of the rotating shaft of the first handle 41, and the first driving rod 43 is slidably connected to the window frame 10, the second driving rod 44 is rotatably connected to the window frame 10, and the first driving rod 43 and the second driving rod 44 are arranged in an "L" shape. One end of the first driving rod 43 is used to abut against the lever 42, the other end of the first driving rod 43 is rotatably connected to one end of the second driving rod 44, the other end of the second driving rod 44 abuts against the first limiting pin 46, and the two ends of the first tension member 45 are respectively connected to the window frame 10 and the other end of the second driving rod 44, and the lever 42 is used to drive the first driving rod 43 to move.

[0034] It should be noted that, combiningFigure 2 , Figure 7 and Figure 8 , a limit hole 21 is provided on the first sash 20. When the first sash 20 is in the closed state as shown in Figure 1 and Figure 2 , the first handle 41 is vertically downward, and the lever 42 installed at the end of the rotating shaft of the first handle 41 is inserted into the limit hole 21. At this time, the rotation of the first sash 20 relative to the window frame 10 is blocked by the lever 42.

[0035] In an embodiment of the present invention, when the first handle 41 is rotated to the position shown in Figure 7 , at this time, the lever 42 moves from the horizontal state to the vertical state, and the first sash 20 can rotate freely at this time.

[0036] In an embodiment of the present invention, in combination with Figure 7 and Figure 8 , when the first sash 20 is opened, after the first handle 41 drives the lever 42 to rotate to the vertical position, the lever 42 presses the first driving rod 43 downward. The downward moving first driving rod 43 will cause the right end of the second driving rod 44 to move downward, and then cause the left end of the second driving rod 44 to move upward. At this time, the first limit pin 46 provided at the left end of the second driving rod 44 will move upward. In combination with Figure 6 , at this time, the first limit pin 46 will block the sliding of the second mounting block 322 in the second chute, and then limit the opening angle of the first sash 20 within a small range to ensure the safety of users.

[0037] In an embodiment of the present invention, when the use scenario is no longer dangerous, the limit unit 40 can be used to release the limit on the second mounting block 322, so that the first sash 20 can be opened at a larger angle relative to the window frame 10, so that the window with an adjustable sash position can obtain a larger ventilation area.

[0038] In an embodiment of the present invention, referring to Figure 8 , when it is necessary to release the limit of the first limit pin 46 on the second mounting block 322, the first handle 41 is rotated again to make the lever 42 move to the horizontal position. At this time, the end of the lever 42 away from the first driving rod 43 releases the extrusion on the first lever 42. Under the action of the first tension member 45, the left end of the second driving rod 44 is pulled downward, and the first limit pin 46 in contact with the left end of the second driving rod 44 will move downward. At this time, the first limit pin 46 will release the limit on the second mounting block 322, so that the first sash 20 can rotate at a larger angle to obtain better ventilation.

[0039] In an embodiment of the present invention, in combination with Figure 11 and Figure 12, when releasing the limit of the second mounting block 322 by the first limit pin 46, the first handle 41 can be rotated clockwise or counterclockwise.

[0040] In an embodiment of the present invention, in order to avoid interference with the movement of the limiting unit 40, a slideway / blind hole is provided in the window frame 10. The lever 42, the first driving rod 43, the second driving rod 44, and the first and the first limit pin 46 are all arranged inside the window frame 10.

[0041] Combined Figure 9 with Figure 10 , a first through hole 11 is provided on the window frame 10, a second through hole 312 is provided on the first mounting plate 311, and the first limit pin 46 passes through the first through hole 11 and the second through hole 312 and extends upward into the chute. When the lever 42 is in the vertical state, the upper end of the first limit pin 46 extends out of the second through hole 312 to limit the second mounting block 322. When the lever 42 is in the horizontal state, the upper end of the second limit pin 46a is located inside the second through hole 312.

[0042] In an embodiment of the present invention, in order to facilitate the operation of the first handle 41, referring to Figure 13 , a limit rod 60 is further provided in the window frame 10. The limit rod 60 is installed beside the first handle 41. There are two limit rods 60, and the two limit rods 60 are used in cooperation to limit the rotation angle of the first handle 41.

[0043] In an embodiment of the present invention, combined Figure 1 , Figure 3 , Figure 12 and Figure 13 , in the initial state, the lever 42 is in the horizontal state, and the lever 42 limits the first window sash 20 from opening. At this time, the first window sash 20 is closed. When the first handle 41 is rotated so that the lever 42 is vertical, the vertical lever 42 abuts against the first driving rod 43, and then the first limit pin 46 extends out of the second through hole 312 to limit the second mounting block 322. Then the angle at which the first window sash 20 can be opened is as Figure 3 shown. In the open state, if it is necessary to release the limit on the first window sash 20, at this time, the first handle 41 is rotated clockwise again so that the lever 42 is in the horizontal state. After the limit of the first mounting block 321 is released, the first window sash 20 can be rotated to a larger angle, so that the window capable of adjusting the position of the window sash can take into account both the safety in use and the ventilation effect.

[0044] While controlling the rotation angle of the first window sash 20 through the first bolt, the limiting unit 40 can also control the opening and closing of the first window sash 20 through the cooperation of the first handle 41 and the lever 42. That is, the cooperation between the first handle 41 and the lever 42 in the limiting unit 40 can not only fix the position of the first window sash 20, but also control the opening angle of the first window sash 20 relative to the window frame 10 through the cooperation of the first bolt.

[0045] To make the first window sash 20 more stable during movement, referring to Figure 3 and Figure 4 , the window with an adjustable window sash position further includes a second hinge 50. The first hinge 30 and the second hinge 50 are respectively installed below and above the first window sash 20, and the first hinge 30 and the second hinge 50 cooperate to control the rotation of the first window sash 20.

[0046] Referring to Figure 4 , the second hinge 50 includes a second fixed structure 51 and a second movable structure 52. The second fixed structure 51 is installed on the window frame 10, and the second movable structure 52 is respectively connected to the second fixed structure 51 and the first window sash 20.

[0047] In an embodiment of the present invention, referring to Figure 7-9 , to make the limiting effect of the limiting unit 40 on the first window sash 20 better, the limiting unit 40 further includes a third driving rod 43a, a fourth driving rod 44a, a second tension member 45a and a second limiting pin 46a for limiting the second movable structure 52. The third driving rod 43a is slidably connected to the window frame 10, the fourth driving rod 44a is rotatably connected to the window frame 10, and the third driving rod 43a and the fourth driving rod 44a are arranged in an "L" shape. One end of the third driving rod 43a is used to abut against the lever 42, the other end of the third driving rod 43a is rotatably connected to one end of the fourth driving rod 44a, the other end of the fourth driving rod 44a abuts against the second limiting pin 46a, and both ends of the second tension member 45a are respectively connected to the window frame 10 and the other end of the fourth driving rod 44a. The third driving rod 43a is driven by the lever 42 to move.

[0048] In an embodiment of the present invention, the working principle of the second limiting pin 46a is the same as that of the first limiting pin 46, and will not be elaborated here.

[0049] In an embodiment of the present invention, the lever 42 includes a first part and a second part. The first part and the second part are respectively arranged on both sides of the rotating shaft of the first handle 41. The first part is used to drive the first driving rod 43, and the second part is used to drive the third driving rod 43a. Smooth curved surfaces such as inclined surfaces 47 are provided on both the first part and the second part, so that the first driving rod 43 and the third driving rod 43a are smoothly driven when abutting against the lever 42.

[0050] In an embodiment of the present invention, in order to prevent rainwater from entering the room along the gap between the first window sash 20 and the window frame 10 when it rains, a boss 70 is provided at the edge of the window frame 10, and the boss 70 is used to seal the edge of the first window sash 20. Further, a rubber strip is provided on the inner wall of the boss 70. When the first window sash 20 is closed, the first window sash 20 presses against the rubber strip to obtain a better sealing effect.

[0051] In an embodiment of the present invention, for the convenience of opening the first window sash 20, refer to Figure 1 , a second handle 80 is provided on the first window sash 20.

[0052] It should be noted that the sliding of the second mounting block 322 in the chute and the rotation of the first handle 41 relative to the window frame 10 both have a certain damping, so that the position of the first window sash 20 can be maintained.

[0053] In an embodiment of the present invention, a second window sash 90 can also be provided. The second window sash 90 can be fixedly connected to the window frame 10 or, similar to the first window sash 20, be connected to the window frame 10 through a hinge.
