Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to an aluminum alloy door and window with a concealed drainage structure. Background Technology
[0002] Aluminum alloy doors and windows are products made primarily of aluminum alloy. They offer numerous advantages. Firstly, aluminum alloy has a low density and is lightweight, making it easy to install and use. At the same time, it possesses high strength, capable of withstanding significant external forces and resisting deformation. Secondly, aluminum alloy doors and windows have excellent sealing properties, effectively blocking dust, rainwater, and noise, creating a quiet and comfortable indoor environment. Furthermore, they are highly corrosion-resistant, rust-resistant, and have a long service life, adapting to various climatic conditions. In terms of appearance, aluminum alloy doors and windows can undergo various surface treatment processes, such as oxidation and spraying, resulting in a rich variety of colors and lusters, offering high decorative appeal and matching different architectural styles.
[0003] Common drainage solutions for aluminum alloy doors and windows include the following: exposed drainage holes, where drainage holes are directly opened at the bottom of the window frame. The structure is simple but it is easy to get clogged and affects the appearance. Built-in drainage channels, where drainage channels are set inside the window frame and drainage is carried out through concealed drainage holes. The appearance is better, but the channels are prone to dust accumulation and the drainage efficiency decreases after long-term use. Inclined drainage grooves, where inclined grooves are designed at the bottom of the window frame to guide the water flow out by gravity. The drainage efficiency is high, but the grooves are prone to dirt accumulation and are difficult to clean.
[0004] Traditional aluminum alloy doors and windows mostly have an exposed drainage structure, which means that drainage holes are opened at the bottom of the window frame and rainwater is discharged through the drainage holes. Although this design is simple, it has problems such as easy clogging of drainage holes, affecting aesthetics and low drainage efficiency. Therefore, an aluminum alloy door and window with a hidden drainage structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an aluminum alloy door and window with a concealed drainage structure, aiming to improve the problem that the drainage structure of some aluminum alloy doors and windows in the prior art has poor drainage effect and is not aesthetically pleasing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy door and window with a concealed drainage structure, including a window frame, an installation frame fixedly connected to the front side of the window frame, a concealed drainage mechanism provided at the bottom side of the installation frame, a dustproof frame detachably connected to the right side of the concealed drainage mechanism, a quick-release mechanism provided at the top of the dustproof frame, and a glass sealing mechanism provided inside the window frame.
[0007] The concealed drainage mechanism includes a drainage frame, which is externally fixedly connected to the inner bottom side of the window frame.

A waterproof pad is fixedly connected to the bottom of the drainage frame. Multiple drainage holes are provided on the inner bottom side of the window frame. Multiple through holes are provided on the inner right side of the dustproof frame. A water outlet pipe is fixedly connected to the right side of the drainage frame, and a connecting ring is fixedly connected to the outside of the water outlet pipe.
[0008] Through the above technical solution: rainwater enters the drainage frame through the gaps in the window frame and the drainage hole, and flows along the inclined surface to the water outlet pipe to achieve concealed drainage. The dustproof frame cooperates with the water outlet pipe and the docking ring through the through hole, and is detachably connected by the quick-release mechanism to prevent debris from entering the drainage outlet. The glass sealing mechanism ensures the sealing between the window frame and the glass body. The overall structure works together to have the functions of drainage, dust prevention and sealing.

[0010] The filter assembly includes a mounting plate, the bottom of which is magnetically attached to the top of a magnetic plate. A handle is fixedly connected to the top of the mounting plate, and multiple filter frames are fixedly connected to the rear interior side of the mounting plate.
[0011] Through the above technical solution: pulling the handle can overcome the magnetic force to remove the filter component. The filter frame on the back of the mounting plate filters the rainwater entering the drainage frame, blocking impurities such as leaves and dust, ensuring unobstructed drainage channels, and facilitating disassembly and cleaning.
[0012] As a further description of the above technical solution:
[0013] The quick-release mechanism includes a locking post, which is slidably connected to the inside of the dustproof frame. A fixing ring is slidably connected to the outside of the locking post, and a spring is sleeved on the outside of the locking post. A pull plate is fixedly connected to the top of the locking post, and a locking groove is opened on the right side of the inside of the water outlet pipe.
[0014] The above technical solution involves the following steps: When installing the dustproof frame, pull the pull plate to stretch the spring, place the dustproof frame onto the docking ring, release the pull plate, and the locking pin will be engaged with the slot of the water outlet pipe under the spring force to fix the dustproof frame.
[0015] As a further description of the above technical solution:
[0016] The glass sealing mechanism includes a glass body, the outside of which is fixedly connected to the inside of the window frame, and a sealing strip is fixedly connected to the outside of the glass body.
[0017] Through the above technical solution, the sealing strip is tightly attached between the glass body and the window frame, effectively filling the gaps and preventing rainwater, dust, and air from entering the interior of the doors and windows, thus playing a good sealing role and improving the waterproof, sound insulation, and heat insulation performance of the doors and windows.
[0018] As a further description of the above technical solution:
[0019] The filter frame is externally slidably connected to the inside of the window frame, and multiple water outlet holes are provided on the bottom inside of the filter frame.
[0020] Through the above technical solution: the water outlet on the bottom inside the filter frame allows rainwater to pass through, and the fine filter structure can filter impurities in the rainwater, ensuring that rainwater flows smoothly into the drainage frame, while preventing impurities from clogging the drainage channel and maintaining normal drainage operation.
[0021] As a further description of the above technical solution:
[0022] The filter frame is externally slidably connected to the rear inner side of the magnetic plate, and the water outlet pipe is externally fixedly connected to the bottom inner side of the window frame.
[0023] The above technical solution allows the water outlet pipe to drain the filtered rainwater from the drainage frame, and the coordinated operation of all components ensures a smooth and efficient drainage process.
[0024] As a further description of the above technical solution:
[0025] The outer part of the card post is slidably connected to the inside of the card slot, and the bottom of the fixing ring is fixedly connected to the top of the dustproof frame.
[0026] The above technical solution involves fixing the ring to the top of the dustproof frame to provide sliding support for the locking post, ensuring stable sliding of the locking post, and reliably engaging and fixing the dustproof frame with the docking ring.
[0027] As a further description of the above technical solution:
[0028] One end of the spring is fixedly connected to the bottom of the pull plate, and the other end of the spring is fixedly connected to the top of the fixing ring.
[0029] The above technical solution allows for quick and convenient installation and disassembly of the dustproof frame and the docking ring: pulling the pull plate stretches the spring, which moves the locking pin; when the pull plate is released, the spring force resets the locking pin.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, rainwater flows in through the gaps in the window frame and the drainage holes, and then flows along the inclined surface to the outlet pipe. The entire drainage process is hidden inside the window frame, which does not affect the appearance of the doors and windows and improves aesthetics. The inclined design of the drainage frame, the reasonable distribution of drainage holes, and the outlet pipe with the appropriate pipe diameter conform to the characteristics of water flow, ensuring that rainwater is discharged quickly and avoiding water accumulation. The filter frame in the filter assembly can also effectively filter impurities, prevent the drainage channel from being blocked, and further ensure drainage efficiency.
[0032] 2. In this utility model, during disassembly, pulling the pull plate causes the locking pin to overcome the spring force and disengage from the slot on the water outlet pipe. The spring is stretched, and the dustproof frame can be removed. During installation, similarly, pulling the pull plate stretches the spring, and the through hole of the dustproof frame is fitted over the water outlet pipe and the connecting ring. Releasing the pull plate causes the locking pin to reset and lock into the slot under the action of the spring force. The operation is simple and quick, and it is convenient to clean the dustproof frame in a timely manner, ensuring that the drain outlet is unobstructed. Attached Figure Description

[0040] 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.
[0041] Reference Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of an aluminum alloy door and window with a concealed drainage structure, including a window frame 1, which serves as the basic frame of the aluminum alloy door and window. A mounting frame 2 is fixedly connected to the front of the window frame 1, serving as an auxiliary installation and decorative element. A concealed drainage mechanism 3 is provided at the bottom of the mounting frame 2. A dustproof frame 4 is detachably connected to the right side of the concealed drainage mechanism 3. The main function of the dustproof frame 4 is to prevent debris from entering the drain outlet and avoid clogging the drainage channel. A quick-release mechanism 5 is provided at the top of the dustproof frame 4. A glass sealing device is provided inside the window frame 1. The sealing mechanism 6 and the concealed drainage mechanism 3 include a drainage frame 31. The drainage frame 31 is designed with an incline, with one end near the drain outlet lower than the other end, facilitating natural water drainage and conforming to the natural flow law of water. This ensures that rainwater entering the drainage frame 31 flows smoothly to the outlet pipe 37, preventing water accumulation. The drainage frame 31 is externally fixedly connected to the inner bottom side of the window frame 1. A magnetic plate 32 is fixedly connected to the top of the drainage frame 31. The main function of the magnetic plate 32 is to magnetically attract the mounting plate 332 in the filter assembly 33, allowing the filter assembly 33 to be securely installed on the drainage frame 31. Meanwhile, when the filter frame 333 needs cleaning, the filter assembly 33 can be easily removed by overcoming the magnetic force. The filter assembly 33 is set on the top of the magnetic plate 32, and a waterproof pad 34 is fixedly connected to the bottom of the drainage frame 31. The waterproof pad 34 fits tightly between the drainage frame 31 and the window frame 1, filling the gaps and further enhancing the sealing performance to prevent rainwater from leaking from the bottom of the drainage frame 31, ensuring the waterproof performance of the doors and windows. Multiple drainage holes 35 are opened on the bottom side of the inside of the window frame 1. The drainage holes 35 serve as channels for rainwater to enter the drainage frame 31. Their reasonable distribution allows for timely drainage. Rainwater entering through the gap in the window frame 1 is guided into the interior of the drainage frame 31 to ensure timely and effective drainage. Multiple through holes 36 are provided on the right side of the interior of the dustproof frame 4. The through holes 36 ensure that rainwater can be smoothly discharged from the outlet pipe 37. The outlet pipe 37 is fixedly connected to the right side of the drainage frame 31. The outlet pipe 37 is fixedly connected to the bottom inside of the window frame 1. A docking ring 38 is fixedly connected to the outside of the outlet pipe 37. The docking ring 38 is used to achieve a detachable connection with the dustproof frame 4 through the quick-release mechanism 5, which facilitates the installation and removal of the dustproof frame 4 for cleaning and maintenance.
[0042] Specifically, rainwater flows through the gaps in the window frame 1 into the reasonably distributed drainage holes 35, enters the inclined drainage frame 31, and flows naturally to the outlet pipe 37 by gravity, avoiding water accumulation. The magnetic plate 32 at the top of the drainage frame 31 is magnetically attracted to the mounting plate 332 of the filter assembly 33, making the filter frame 333 stable and easy to clean. The bottom waterproof pad 34 enhances the sealing and prevents leakage. The outlet pipe 37 on the right side of the drainage frame 31 is connected to a connecting ring 38, which is connected to the dustproof frame 4 through a quick-release mechanism 5. Pulling the pull plate 54 moves the locking post 51 to overcome the elasticity of the spring 53, which can realize the quick disassembly and assembly of the dustproof frame 4, making it easy to clean and preventing debris from clogging the drainage outlet. Its internal through hole 36 ensures smooth drainage. The glass sealing mechanism 6 inside the window frame 1 is tightly attached to the glass body 61 and the window frame 1 through the sealing strip 62, effectively blocking rainwater, dust and air, and improving the waterproof, sound insulation and heat insulation performance of the doors and windows.
[0043] Reference Figure 1 , Figure 2 and Figure 4 The filter assembly 33 includes a mounting plate 332, which is made of a metal material with a certain strength and magnetic conductivity. Its surface is flat and smooth, and it is in close contact with the magnetic plate 32 to ensure a stable magnetic attraction effect. The bottom of the mounting plate 332 is magnetically attached to the top of the magnetic plate 32. A handle 331 is fixedly connected to the top of the mounting plate 332. The handle 331 allows the operator to pull the mounting plate 332 to remove and install the filter assembly 33. Multiple filter frames 333 are fixedly connected to the rear side of the interior of the mounting plate 332. The exterior of the filter frames 333 is slidably connected to the interior of the window frame 1. Multiple water outlet holes are opened on the bottom side of the interior of the filter frames 333. The filter frames 333 are made of fine metal mesh or filter material, which can effectively filter impurities carried in rainwater, such as leaves and dust, to prevent these impurities from entering the interior of the drainage frame 31 and affecting the drainage effect. The exterior of the filter frames 333 is slidably connected to the rear side of the interior of the magnetic plate 32.
[0044] Specifically, the handle 331 allows the operator to pull the mounting plate 332 to disassemble and install the filter assembly 33. Multiple filter frames 333 are fixedly connected to the rear side of the mounting plate 332. Their exterior can slide inside the window frame 1 and the rear side of the magnetic plate 32. Multiple water outlet holes are opened on the bottom side of the interior. The filter frames 333, made of fine metal mesh or filter screen material, can effectively filter impurities such as leaves and dust in rainwater, allowing rainwater to flow into the drainage frame 31 through the water outlet holes. This prevents impurities from entering the drainage frame 31 and affecting the drainage effect, and also makes it easy to disassemble for cleaning and maintenance.
[0045] Reference Figure 1 , Figure 2 and Figure 5The quick-release mechanism 5 includes a locking post 51, which is externally slidably connected to the inside of the dustproof frame 4. When the dustproof frame 4 is installed on the docking ring 38, the locking post 51 is engaged into the slot 55 under the elastic force of the spring 53, thus fixing the dustproof frame 4. A fixing ring 52 is externally slidably connected to the locking post 51. The main function of the fixing ring 52 is to provide sliding support for the locking post 51. The bottom of the fixing ring 52 is fixedly connected to the top of the dustproof frame 4. A spring 53 is sleeved on the outside of the locking post 51. One end of the spring 53 is fixedly connected to the bottom of the pull plate 54, and the other end of the spring 53 is fixedly connected to the top of the fixing ring 52. The function of the spring 53 is to provide a reset elastic force for the locking post 51. When the pull plate 54 is pulled to disengage the locking post 51 from the slot 55, and the pull plate 54 is released, the spring 53 can push the locking post 51 back to reset, causing it to re-engage into the slot 55, thus achieving quick release of the dustproof frame 4. The quick installation and disassembly are achieved by a pull plate 54 fixedly connected to the top of the locking post 51. The operator moves the locking post 51 by pulling the pull plate 54, thereby connecting and separating the dustproof frame 4 and the docking ring 38. A slot 55 is provided on the right side of the inside of the water outlet pipe 37. The outside of the locking post 51 is slidably connected to the inside of the slot 55. The slot 55 is used to cooperate with the locking post 51 to achieve the locking and fixing between the dustproof frame 4 and the docking ring 38. The glass sealing mechanism 6 includes a glass body 61. The glass body 61 is the key structure for the door and window to achieve the functions of lighting and ventilation. The outside of the glass body 61 is fixedly connected to the inside of the window frame 1. A sealing strip 62 is fixedly connected to the outside of the glass body 61. The sealing strip 62 is tightly fitted between the glass body 61 and the window frame 1 to fill the gap between the two and prevent rainwater, dust, air and other substances from entering the inside of the door and window, thus playing a good sealing role.
[0046] Specifically, when installing the dustproof frame 4, it is fitted onto the connecting ring 38. The spring 53 causes the locking post 51 to engage with the slot 55 on the right side inside the water outlet pipe 37, thus fixing the dustproof frame 4. When disassembling, the operator pulls the pull plate 54 to move the locking post 51 away from the slot 55, overcoming the spring 53's elasticity, and the dustproof frame 4 can be removed. After releasing the pull plate 54, the spring 53 pushes the locking post 51 back to its original position for the next installation. At the same time, in the glass sealing mechanism 6, the glass body 61 is fixed inside the window frame 1, and the external sealing strip 62 tightly adheres to the glass body 61 and the window frame 1, filling the gaps and effectively preventing rainwater, dust, and air from entering the door and window, ensuring the sealing performance of the door and window.
[0047] Working principle: Rainwater enters the interior of the drainage frame 31 through the gaps in the window frame 1 and the drainage hole 35, flowing along the inclined drainage frame 31 to the outlet pipe 37. At this time, the rainwater is filtered by the filter frame 333, thus preventing impurities from entering the interior of the drainage frame 31 and affecting the drainage effect. When it is necessary to clean the filter frame 333, pull the handle 331 to overcome the magnetic force between the mounting plate 332 and the magnetic plate 32 to remove the filter assembly 33 from the drainage hole 35, making it easy to clean. The rainwater is finally discharged through the dustproof frame 4, which prevents debris from entering the drain outlet. When it is necessary to install or remove the dustproof frame 4, pull the pull plate 54 to drive the locking post. Displacement occurs when 51 disengages from the inside of the slot 55, causing the spring 53 to stretch. This allows the dustproof frame 4 to be removed from the outside of the docking ring 38, enabling disassembly of the dustproof frame 4 for cleaning. When installation is required, pulling the pull plate 54 stretches the spring 53, allowing the through hole 36 to be fitted over the outside of the drain pipe 37 and the docking ring 38. Then, releasing the pull plate 54 allows the locking post 51 to reset using the elastic force of the spring 53, enabling the locking post 51 to engage with the inside of the docking ring 38 for installation. The sealing strip 62 and waterproof gasket 34 ensure the seal between the window frame 1 and the glass body 61, preventing water leakage.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
