[0002] Metal door and window manufacturing refers to the production activities of making building doors, windows, and similar products using metal materials (such as aluminum alloys, steel, copper, etc.). Depending on the materials used, metal doors and windows can be divided into several types, the most common being aluminum alloy doors and windows, PVC doors and windows (although the main material is plastic, it is often mentioned as a comparison option for metal doors and windows), and thermally broken aluminum doors and windows.

[0003] Referring to patent application CN218716423U, a privacy metal door and window is disclosed, relating to the field of door frames. Several hinge plates are fixed between the two sides of the inner shell. One end of each hinge plate is connected to a rack, and the other end of the rack is connected to a first gear. The first gear is connected to a roller located on the side of the outer shell. The first and second glass panes are respectively installed on the outer sides of the inner and outer baffles of the outer shell and are fixedly connected by a pressure strip. The handle is located at the top of one side of the outer shell, with a latch connected to its inner side. This invention provides privacy to the metal door and window by setting hinge plates and racks between the two layers of glass, and rotating the hinge plates through rollers. The handle and latch located above the door and window allow the door and window to be opened and closed, and can be opened for ventilation.

[0004] As shown in the prior art above, metal doors and windows with privacy functions in the prior art usually require the installation of curtains or blinds to achieve privacy protection. However, the installation of blinds and curtains is not only cumbersome but also inconvenient for daily cleaning.

[0005] Therefore, it is necessary to provide a protective mechanism for metal doors and windows to solve the above-mentioned technical problems. Utility Model Content

[0027] 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.

[0028] This utility model provides two technical solutions:

[0029] Figures 1 to 4 The first implementation is shown:

[0030] A protective mechanism for metal doors and windows includes a window frame 1, a glass window 2 symmetrically and rotatably connected to one side of the window frame 1, a protective railing 3 fixed to the inner wall of the window frame 1, an avoidance frame 4 symmetrically fixed to the lower part of the inner wall of the window frame 1, and a push-pull handle 5 fixed to the lower part of the glass window 2 near the protective railing 3 at the position corresponding to the avoidance frame 4.

[0031] An n-shaped frame 6 is slidably connected to the side of the window frame 1 away from the glass window 2. A curtain 7 is hung above the n-shaped frame 6. A buckle assembly is symmetrically installed below the window frame 1. The buckle assembly is used to lock the n-shaped frame 6 in the top position. When the buckle assembly is unlocked, the n-shaped frame 6 moves down to facilitate the removal of the curtain 7.

[0032] A slider 8 is symmetrically fixed at the upper end of the n-shaped frame 6. A sliding groove 9 is symmetrically opened on the side of the window frame 1 near the n-shaped frame 6. The slider 8 is slidably connected to the inner wall of the sliding groove 9. A limit block 10 is symmetrically fixed at the lower side of the window frame 1 near the n-shaped frame 6. The two sides of the n-shaped frame 6 are slidably connected to the inner walls of the two limit blocks 10 respectively. A handle 11 is symmetrically fixed at the lower ends of both sides of the n-shaped frame 6.

[0033] The buckle assembly includes a fixing block 12 fixed below the handle 11, and outer shells 13 symmetrically fixed on both sides of the window frame 1. A locking block 14 is slidably connected to the inner wall of the outer shell 13. A locking groove 15 is opened on the side of the fixing block 12 near the locking block 14 corresponding to the locking block 14. A spring 16 is fixed on the side of the locking block 14 away from the locking groove 15. The end of the spring 16 away from the locking block 14 is fixed to the inner wall of the outer shell 13. A pull rod 17 is fixed on the side of the locking block 14 near the spring 16. The pull rod 17 is slidably connected to the inner wall of the outer shell 13. A knob 18 is rotatably connected to the end of the pull rod 17 away from the locking block 14 through the outer shell 13.

[0034] A positioning block 19 is fixed on the side of the outer casing 13 near the knob 18. The knob 18 is oval in shape. When the knob 18 is rotated so that one side of it contacts the end of the positioning block 19 away from the outer casing 13, it can prevent the spring 16 from rebounding.

[0035] The n-shaped frame 6 and the window frame 1 are connected by a sliding connection, which allows the n-shaped frame 6 to move up and down easily. When the curtain 7 needs to be removed for cleaning or replacement, the user only needs to unlock the buckle assembly to easily move the n-shaped frame 6 down, which greatly simplifies the operation process.

[0036] Figure 1 The second embodiment is shown, and its main difference from the first embodiment is:

[0037] Several C-shaped buckles 20 are hung above the n-shaped frame 6, and several hanging rings 21 are fixed above the curtain 7 corresponding to the C-shaped buckles 20.

[0038] The fabric curtain 7 in this patent can be easily removed and placed in a washing machine for cleaning. Compared to traditional curtains or blinds, the cleaning process is simpler and faster, greatly saving users' time and effort. Furthermore, because the fabric curtain 7 is easy to replace, users can choose different colors and materials according to personal preferences or seasonal changes, increasing its flexibility and convenience.

[0039] Working principle:

[0040] The window frame 1 serves as the supporting structure, the glass window 2 is used for lighting and ventilation, the guardrail 3 provides basic safety protection, and the clearance frame 4 and the push-pull handle 5 facilitate the opening and closing of the glass window 2. The n-shaped frame 6 is used to hang the curtain 7 to achieve the function of privacy protection, while the buckle assembly is used to lock the n-shaped frame 6 in the top position to ensure the stability of the curtain 7.

[0041] Since the curtain 7 is connected to several C-shaped buckles 20 on the n-shaped frame 6 via the hanging ring 21, the curtain 7 is very easy to remove and clean; the n-shaped frame 6 can be lowered when the curtain 7 is hung or removed, which effectively prevents the safety hazards caused by users climbing the curtain 7.

[0042] Unlocking the two latching components allows the n-shaped frame 6 to move downwards. Pulling the knob 18 away from the slot 15 causes the pull rod 17 and the locking block 14 to slide simultaneously on the inner wall of the outer casing 13, compressing the spring 16. When the knob 18 rotates to contact the end of the positioning block 19 away from the outer casing 13, the locking block 14 is positioned inside the outer casing 13. At this point, the locking block 14 disengages from the slot 15, completing the unlocking of the latching components. Holding one of the handles 11, the n-shaped frame 6 is gradually lowered, while the slider 8 moves simultaneously on the inner wall of the slide groove 9 until the slider 8 contacts the top of the limiting block 10, at which point the n-shaped frame 6 slides to its lowest point, allowing the curtain 7 to be removed or placed.

[0043] When the n-shaped frame 6 needs to be reset to its top position, the knobs 18 and springs 16 on the two latching assemblies must first be reset. At this time, the knobs 18 are located at the end of the positioning block 19 near the outer shell 13. Hold the handle 11 and move the n-shaped frame 6 upward. When the fixing block 12 approaches the locking block 14, it will press the inclined surface of the locking block 14 to make the locking block 14 enter the outer shell 13. When the locking block 14 is aligned with the locking slot 15, the spring 16 will automatically rebound and lock the locking block 14 into the locking slot 15, thus completing the locking of the n-shaped frame 6 in the top position.
