Technical Field
[0001] This utility model relates to the field of metal doors and windows, specifically a metal door and window that is easy to disassemble. Background Technology
[0002] Metal doors and windows are architectural door and window products made primarily of metal materials such as aluminum alloy, stainless steel, and steel. Their core characteristics are high strength and durability, while also providing security and decorative functions. Aluminum alloy doors and windows are the mainstream choice due to their lightweight, corrosion resistance, and good plasticity; their surfaces can be achieved in various colors through anodizing or spraying processes. Stainless steel doors and windows are suitable for humid environments due to their excellent rust resistance. Steel doors and windows emphasize sturdiness and are commonly found in locations with high security requirements.
[0003] For example, authorization notice number CN220565953U describes a metal door and window that is easy to clean.

Two sliders are rotatably mounted with connecting rods that are rotatably connected to the door / window. The other two sliders are rotatably mounted with connecting rods that are rotatably connected to the door / window. The device also includes a motor, a lead screw, and a brush. The motor is mounted on the frame, and a lead screw is mounted on the motor's output shaft via a coupling. The lead screw is threaded onto the lead screw. When the motor is turned on, the motor's output shaft rotates, causing the lead screw to rotate, which in turn moves the brush to the left to clean dust and other impurities from the door / window surface, thus facilitating quick cleaning of the door / window surface.

Specific implementation manners
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0024] Please refer to Figure 1-5, an embodiment provided by the present utility model: a metal door and window that is easy to disassemble, including a door and window frame 1. At the upper and lower ends of the middle part on one side of the front end face of the door and window frame 1, rectangular slots 103 are provided. Between the two rectangular slots 103 and inside the door and window frame 1, they are connected through a rectangular through slot 104. In the middle of the rectangular through slot 104, a transmission cavity 105 is provided. In the middle of the interior of the transmission cavity 105, a first rotating shaft 2 is rotatably connected. The upper and lower ends of the first rotating shaft 2 are respectively inserted into the upper and lower ends of the interior of the rectangular through slot 104 and are fixedly connected with screw rods 201. At the upper and lower ends of the interior of the rectangular through slot 104, rectangular pin rods 3 are provided. The front end of the door and window frame 1 is connected with a door and window sash 5. At the upper and lower ends of the middle part on one side of the door and window sash 5, rectangular inserts 501 are rotatably connected. Between the two rectangular inserts 501 and the door and window sash 5, they are rotatably connected through hinges 502. The two rectangular inserts 501 are respectively inserted into the two rectangular slots 103. In the middle of the two rectangular inserts 501, a vertical rectangular through hole 503 is provided. In the middle of the upper end face of the interior of the upper rectangular slot 103 and in the middle of the lower end face of the interior of the lower rectangular slot 103, rectangular limiting slots 106 are provided. The outer ends of the two rectangular pin rods 3 pass through the rectangular through holes 503 of the two rectangular inserts 501 and are respectively inserted into the two rectangular limiting slots 106. By the two rectangular pin rods 3 passing through the two rectangular inserts 501, the door and window frame 1 and the door and window sash 5 are fixed, and the door and window sash 5 is opened through the two hinges 502.
[0025] Please refer to Figure 3 , on the rear end of the inner end face of the door and window frame 1, a limiting border 101 is fixedly connected. On the front end face of the limiting border 101, a sealing ring 102 is fixedly connected. When the door and window sash 5 rotates backward and is inserted into the interior of the door and window frame 1 to close, the edge of the rear end face of the door and window sash 5 squeezes the sealing ring 102 to achieve sealing between the door and window frame 1.
[0026] Please refer to Figure 2 , Figure 4 and Figure 5, internal thread grooves 301 are provided inside the adjacent ends of the two rectangular pin rods 3. The screw rods 201 at the upper and lower ends of the first rotating shaft 2 are respectively inserted into the two internal thread grooves 301 and are threadedly connected to the rectangular pin rods 3. In the middle of the front end face of the door and window frame 1 and fixed to the front end of the transmission cavity 105 is a limit tube 107. A knob 4 is provided at the front end of the limit tube 107. In the middle of the rear end of the knob 4 is fixedly connected a second rotating shaft 401. The rear end of the second rotating shaft 401 passes through the limit tube 107 and extends into the transmission cavity 105 and is fixedly connected with a second bevel gear 402. In the middle of the first rotating shaft 2 is fixedly connected a first bevel gear 202. The first bevel gear 202 is meshed with the tooth part of the second bevel gear 402. When it is necessary to disassemble the door and window sash 5, by rotating the knob 4, the knob 4 drives the second rotating shaft 401 to rotate. The second rotating shaft 401 drives the first rotating shaft 2 and the two screw rods 201 to rotate through the meshing of the tooth parts of the first bevel gear 202 and the second bevel gear 402. Furthermore, when the two screw rods 201 rotate, they synchronously drive the two rectangular pin rods 3 to respectively disengage from the rectangular through holes 503 of the two rectangular inserts 501 and retract into the upper and lower ends of the rectangular through groove 104, and then the two rectangular inserts 501 can be pulled out of the rectangular slot 103, realizing the separation between the door and window sash 5 and the door and window frame 1.
[0027] Working principle: During use, first rotate the door and window sash 5 to the open state through the hinge 502, and insert the two rectangular inserts 501 into the rectangular slots 103 on the door and window frame 1. When it is necessary to fix, rotate the knob 4 to drive the second rotating shaft 401 and the second bevel gear 402 to rotate, and drive the first rotating shaft 2 and the two screw rods 201 at both ends to rotate synchronously through gear meshing. Since the screw rod 201 is in threaded fit with the internal thread groove 301 of the rectangular pin rod 3, the two rectangular pin rods 3 will extend outwards along the rectangular through groove 104, sequentially pass through the rectangular through holes 503 of the rectangular inserts 501 and be inserted into the rectangular limit grooves 106, thus completing the mechanical locking of the door and window sash 5. When disassembling, rotate the knob 4 in the reverse direction, and the rectangular pin rod 3 retracts and disengages from the rectangular through hole 503, and then the entire door and window sash 5 can be removed. The sealing ring 102 is compressed and deformed during closing to achieve sealing, and the limit frame 101 ensures the accurate alignment of the door and window sash 5.
[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
