[0004] Most existing metal doors and windows adopt a relatively traditional design, usually consisting of a screen window on the indoor side and a glass window on the outdoor side. However, when users want to open the outdoor glass window for ventilation, they must first open the screen window on the indoor side, which is cumbersome and lacks flexibility. Therefore, this utility model provides a metal door and window structure with multiple opening methods. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a metal door and window structure with multiple opening methods, solving the problem that when users want to open the outdoor glass window for ventilation, they must first open the screen window on the indoor side, which is a cumbersome and inflexible operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal door and window structure with multiple opening methods, including a window frame, an exterior glass window hinged to one side of the window frame facing the outside, a straight groove at the bottom of the exterior glass window, a base plate installed at the bottom of the window frame, a shaped groove on the base plate, and the shaped groove having a through structure on both sides facing the interior and exterior, and a linkage component inside the shaped groove for opening or closing the exterior glass window from the interior; the linkage component includes a rotating rod rotatably mounted on the shaped groove, a lever mounted on the top surface of the rotating rod facing the exterior, and the lever being movably mounted inside the straight groove.
[0007] Preferably, a connecting rod is mounted on the surface of the rotating rod facing the interior, and a second handle is mounted on one side surface of the connecting rod, with the second handle located inside the room.

[0009] Preferably, a limiting groove is provided on the irregular groove, and a counterweight is fixedly connected to the surface of the pressing block facing the bottom plate, and the counterweight can be engaged with the limiting groove.
[0010] Preferably, a lock groove is provided on the inner wall of one side of the window frame, and a rod groove that cooperates with the lever is provided on the surface of the window frame facing the outside.
[0011] Preferably, an inner screen window facing the interior is hinged to the other side of the window frame. The inner screen window has a first handle on the surface facing the interior. A pivot is installed on the outer surface of the first handle. The pivot moves through the surface of the inner screen window and extends to the other side. A lock piece that cooperates with the lock groove is installed at the end of the pivot.
[0012] Beneficial effects
[0013] This utility model provides a metal door and window structure with multiple window opening methods. Compared with the prior art, it has the following advantages:
[0014] 1. This metal door and window structure with multiple opening methods allows for the rotation of a rotating rod by pushing or pulling the second handle. The lever on the rotating rod moves within a straight groove, and the rotation of the rotating rod causes the lever to push or pull the outer glass window, thereby opening or closing the outer glass window around its hinge point with the window frame. This enables the opening or closing of the outer glass window from inside the room, overcoming the problem that existing metal doors and windows require opening the screen window before operating the glass window. It provides a more flexible and convenient window opening method, meeting users' needs for multiple window opening methods and operational flexibility in metal doors and windows.
[0015] 2. This metal door and window structure with multiple opening methods allows the counterweight to drop downwards due to its own weight and engage with the limiting groove when the outer glass window is closed. This engagement limits the linkage component and prevents the rotating rod from rotating freely. When the user needs to open the outer glass window, applying a certain pressure to the pressing block will cause the counterweight to lift up and separate from the limiting groove, releasing the limitation on the linkage component and allowing the rotating rod to rotate, thereby realizing the opening operation of the outer glass window.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides two technical solutions:
[0027] Figures 1-8 The first embodiment is shown: a metal door and window structure with multiple opening methods, including a window frame 1, an exterior glass window 3 hinged to one side of the window frame 1 facing the outside, a straight groove 31 at the bottom of the exterior glass window 3, a base plate 4 installed at the bottom of the window frame 1, a shaped groove 41 on the base plate 4, and the shaped groove 41 is a through structure on both the interior and exterior sides, and a linkage component 5 is provided inside the shaped groove 41 for opening or closing the exterior glass window 3 from the interior; the linkage component 5 includes a rotating rod 51 rotatably mounted on the shaped groove 41, a lever 52 mounted on the top surface of the rotating rod 51 facing the outside, and the lever 52 is movably mounted inside the straight groove 31. A connecting rod 53 is mounted on the interior side surface of the rotating rod 51, and a second handle 54 is mounted on the interior side surface of the connecting rod 53, and the second handle 54 is located inside the interior.
[0028] Specifically, by pushing or pulling the second handle 54, the rotating rod 51 is driven to rotate. The lever 52 on the rotating rod 51 will move within the straight slot 31. The rotation of the rotating rod 51 will cause the lever 52 to push or pull the outer glass window 3, thereby driving the outer glass window 3 to open or close around its hinge point with the window frame 1, thus realizing the function of opening or closing the outer glass window 3 from the inside.
[0029] Figures 1-8 The second embodiment is shown, and its main difference from the first embodiment is that the connecting rod 53 has a straight slot 55, which is a through structure, and a pressing block 56 is rotatably installed inside the straight slot 55. A limiting groove 42 is provided on the irregular groove 41, and a counterweight 57 is fixedly connected to the surface of the pressing block 56 facing the bottom plate 4, and the counterweight 57 can be engaged inside the limiting groove 42.
[0030] Specifically, when the outer glass window 3 is closed, the counterweight 57 will fall downwards due to its own weight and lock into the limiting groove 42. This locking state can limit the linkage component 5 and prevent the rotating rod 51 from rotating freely. When the user needs to open the outer glass window 3, by applying a certain pressing force to the pressing block 56, the counterweight 57 will lift up and separate from the limiting groove 42, releasing the limitation on the linkage component 5 and allowing the rotating rod 51 to rotate, thereby realizing the opening operation of the outer glass window 3.
[0031] In this embodiment, a lock groove 11 is provided on the inner wall of one side of the window frame 1, and a rod groove 12 that cooperates with the lever 52 is provided on the surface of the window frame 1 facing the outside.
[0032] Specifically, when the outer glass window 3 is closed, the lever 52 will be in the lever groove 12. The lever groove 12 serves to store the lever 52, making the structure of the outer glass window 3 and the window frame 1 more compact and aesthetically pleasing, while preventing the lever 52 from being exposed and causing collisions or damage.
[0033] In this embodiment, an inner screen window 2 facing the interior is hinged to the other side of the window frame 1. A first handle 21 is provided on the surface of the inner screen window 2 facing the interior. A rotating shaft 22 is installed on the outer surface of the first handle 21. The rotating shaft 22 moves through the surface of the inner screen window 2 and extends to the other side. A locking piece 23 that cooperates with the locking groove 11 is installed at the end of the rotating shaft 22.
[0034] Specifically, for the inner screen window 2, when it is necessary to open or close the inner screen window 2, the first handle 21 can be operated. The first handle 21 drives the rotating shaft 22 to rotate, which in turn drives the locking plate 23 to rotate. When the locking plate 23 is engaged with the lock groove 11, the inner screen window 2 is in a locked state; when the first handle 21 is rotated to disengage the locking plate 23 from the lock groove 11, the inner screen window 2 can be opened or closed around its hinge point with the window frame 1, making it convenient for users to operate the screen window on the indoor side.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working principle: When the user needs to open the outer glass window 3, the first step is to release the limit of the linkage component 5. The user applies a downward pressing force to the pressing block 56. Since the pressing block 56 is rotatable in the straight groove 55, after the pressure is applied, the counterweight 57 will lift up and separate from the limit groove 42, releasing the limit on the linkage component 5. Subsequently, the user pushes or pulls the second handle 54 to drive the rotating rod 51 to rotate. The lever 52 on the rotating rod 51 will move in the straight groove 31. The rotation of the rotating rod 51 will cause the lever 52 to push or pull the outer glass window 3, thereby driving the outer glass window 3 to open or close around its hinge point with the window frame 1. This realizes the function of opening or closing the outer glass window 3 from the inside, overcoming the problem that existing metal doors and windows must first open the screen window before operating the glass window. It provides a more flexible and convenient way to open the window, meeting the user's needs for multiple window opening methods and operational flexibility for metal doors and windows.
[0037] When the user closes the outer glass window 3, and after the outer glass window 3 is completely closed, under the gravity of the counterweight 57 of the pressing block 56, the counterweight 57 will re-engage in the limiting groove 42, locking the linkage component 5 again, ensuring that the outer glass window 3 is in a stable closed state.
