Description

Technical Field

[0001] This utility model relates to the field of screen windows, and in particular to a laser-welded narrow-frame quick-release aluminum alloy screen window. Background Technology

[0002] As a core component in residential and commercial buildings that combines ventilation, mosquito prevention, and security, window screens have seen continuous growth in market demand as my country's urbanization process accelerates and the penetration rate of fully furnished apartments increases. At the same time, modern architectural design is increasingly emphasizing "lightweight" and "integrated" aesthetics. Narrow-frame window screens, due to their strong visual transparency and compatibility with mainstream window types such as large glass curtain walls and floor-to-ceiling windows, are seeing their application share in high-rise residential buildings, serviced apartments, and commercial complexes rise year by year.

[0003] However, existing window screens still generally have the following problems: the disassembly and assembly structure mostly relies on screws for fixing, requiring tools for disassembly, which is cumbersome and easily causes frame deformation, resulting in low cleaning and maintenance efficiency, especially unfriendly to the elderly and female users. In addition, the bottom drainage mostly adopts a flat opening design, which makes rainwater easy to accumulate in the frame during rainy days, and is prone to backflow due to outdoor wind. The accumulated water seeps into the room and can easily damage the walls or floors, making it difficult to meet the needs of high-rise residential buildings and rainy areas.

[0004] Therefore, to address the existing problem of inconvenient disassembly and assembly, a quick-release screen window is needed to solve the above problems. Utility Model Content

[0005] To address the inconvenience of disassembly and assembly in existing technologies, this application provides a laser-welded narrow-frame quick-release aluminum alloy screen window.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Laser-welded narrow-frame quick-release aluminum alloy screen window includes a window frame and a mounting frame. The window frame and mounting frame are combined to form a complete screen window. The window frame is rectangular in shape. A fixed mesh is fixedly connected to the inner wall of the window frame. A sliding frame is slidably connected inside the sliding frame. A movable mesh is fixedly connected to the inner wall of the sliding frame. The window frame and mounting frame can be quickly assembled and disassembled through a quick-release assembly. The bottom of the mounting frame is equipped with a drainage assembly to prevent rainwater from accumulating on the frame and seeping into the room.

[0008] As a further improvement of this utility model, the window frame, mounting frame and sliding frame are all made of aluminum alloy and are welded by laser seamless welding process.

[0009] As a further improvement of this utility model, the quick-release assembly includes a latch block slidably connected inside the window frame, a guide rod slidably connected to the right side of the latch block, the side of the guide rod away from the latch block being fixedly connected to the inside of the window frame, a spring being sleeved on the outer wall of the guide rod, one end of the spring being fixedly connected to the latch block, and the other end of the spring being fixedly connected to the inside of the window frame.

[0010] As a further improvement of this utility model, a trigger block is slidably connected to one end of the window frame near the sliding frame. The trigger block has multiple sliding parts, one of which is fixedly connected to a rack one at one end near the locking block, and a rack two is fixedly connected to the front side of the locking block.

[0011] As a further improvement of this utility model, a second gear is rotatably connected inside the window frame, and a second bevel gear is coaxially connected to the side of the second gear near the locking block. A first gear is rotatably connected inside the window frame, and a first bevel gear is coaxially connected to the side of the first gear near the locking block. The first bevel gear and the second bevel gear mesh, the first rack meshes with the first gear, and the second rack meshes with the second gear.

[0012] As a further improvement of this utility model, the drainage component includes a flow guide channel formed at the bottom of the window frame, a filter screen is provided at the top of the flow guide channel, and a check valve is rotatably connected to the bottom of the window frame by a miniature torsion spring, the check valve being located at the bottom of the flow guide channel.

[0013] As a further improvement of this utility model, a combination lock is installed on the adjacent side of the window frame and the sliding frame.

[0014] As a further improvement of this utility model, the outer wall of the window frame is provided with multiple positioning holes, and multiple positioning protrusions are fixedly connected around the window frame to ensure accurate positioning during installation.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. In this utility model, pressing the trigger block can drive rack one, gear one, bevel gear one and bevel gear two, gear two and rack two to move together, so that the buckle extends and retracts along the guide rod, realizing the quick separation of the window frame and the mounting frame. Since the side of the buckle is inclined, during installation, only the window frame needs to be pressed down to quickly connect with the mounting frame, reducing the time spent on disassembly and assembly.

[0017] 2. In this utility model, the drainage structure at the bottom of the window frame can quickly drain rainwater from the bottom of the window frame, preventing rainwater from accumulating and penetrating into the room. The filter screen can block impurities or insects, avoiding clogging of the drainage channel. The check valve is normally closed under the action of a micro torsion spring, and automatically opens when water is discharged from the drainage channel. When closed, it prevents rainwater from flowing back in. Attached Figure Description

[0032] Example 1:

[0033] Reference Figure 1 and Figure 2 Laser-welded narrow-frame quick-release aluminum alloy screen window, including window frame 1 and mounting frame 8, which are combined to form a complete screen window. Window frame 1 is rectangular in shape, and a fixed mesh 3 is fixedly connected to the inner wall of window frame 1. A sliding groove 9 is opened on the inner wall of window frame 1, and a sliding frame 2 is slidably connected inside the sliding groove 9. A movable mesh 4 is fixedly connected to the inner wall of sliding frame 2. The sliding frame 2 can adjust the opening area of ​​the screen window by sliding inside the sliding groove 9, which can be flexibly adjusted according to ventilation needs. Figures 3-5The window frame 1 has a sliding connection with a locking block 11, which is a key component for locking the window frame 1 and the mounting frame 8. The side of the locking block 11 that inserts into the mounting frame 8 is inclined. A guide rod 13 is slidably connected to the right side of the locking block 11. The side of the guide rod 13 away from the locking block 11 is fixedly connected to the interior of the window frame 1. A spring 12 is sleeved on the outer wall of the guide rod 13. One end of the spring 12 is fixedly connected to the locking block 11, and the other end of the spring 12 is fixedly connected to the interior of the window frame 1. The guide rod 13 guides the sliding trajectory of the locking block 11 and the spring 12, preventing the spring 12 from deviating, and ensuring that the locking block 11 can accurately engage with the mounting frame 8. A trigger block 10 is slidably connected to the end of the window frame 1 near the sliding frame 2. It can be slid by manually pushing, driving the movement of subsequent components. The trigger block 10 has multiple sliding parts. One of the sliding parts is fixedly connected to a rack 14 at the end near the locking block 11, and a rack 2 17 is fixedly connected to the front side of the locking block 11. A second gear 18 is rotatably connected, and a second bevel gear 19 is coaxially connected to the side of the second gear 18 near the locking block 11. A first gear 15 is rotatably connected inside the window frame 1, and a first bevel gear 16 is coaxially connected to the side of the first gear 15 near the locking block 11. The first bevel gear 16 and the second bevel gear 19 mesh. A first rack 14 meshes with a first gear 15, and a second rack 17 meshes with a second gear 18. When the trigger block 10 is pushed, the first rack 14 is simultaneously pushed, causing it to mesh with the second rack 17. When gear 15 rotates, since gear 15 is coaxial with bevel gear 16, bevel gear 16 also rotates synchronously. Bevel gear 16 further drives bevel gear 19, which meshes with it, to rotate. Gear 18, which is coaxial with bevel gear 19, rotates synchronously and drives rack 17, which meshes with gear 18, to slide. Finally, it drives the locking block 11, which is fixedly connected to rack 17, to slide, so that the locking block 11 slides out of the mounting frame 8. At this time, the window frame 1 and the mounting frame 8 can be separated.

[0034] The window frame 1, mounting frame 8, and sliding frame 2 are all made of aluminum alloy, which is lightweight, high-strength, corrosion-resistant, and oxidation-resistant. This effectively reduces the weight of the window frame while improving the screen's oxidation resistance and extending its service life. The frames are all welded using a laser seamless welding process, resulting in high weld strength and excellent sealing. This not only enhances the overall structural strength of the screen and prevents breakage or deformation at the weld joints, but also prevents rainwater and dust from entering the window frame through the weld joints and affecting the internal mechanism. The seamless welding also makes the screen more aesthetically pleasing, with no obvious welding marks. A combination lock 5 is installed on the adjacent side of the window frame 1 and the sliding frame 2. Multiple positioning holes 6 are provided on the outer wall of the window frame 1, and multiple positioning protrusions 7 are fixedly connected around the perimeter of the window frame 1. The positioning protrusions 7 cooperate with the positioning holes 6 to form a double positioning effect, ensuring accurate positioning during installation and preventing the screen from tilting or gaps after installation, which would affect the installation effect.

[0035] Example 2:

[0036] As one of the optimized structural designs for Example 1, such as Figure 6 As shown, a drainage channel 22 is provided at the bottom of the window frame 1. The channel is designed with an inclination to guide rainwater out and prevent it from accumulating on the window frame 1. This prevents the aluminum alloy material from corroding and rusting due to long-term contact with water. At the same time, the channel wall of the drainage channel 22 is smoothed to reduce water flow resistance. A filter screen 23 is provided at the top of the drainage channel 22 to effectively block mosquitoes and other debris from entering the drainage channel 22, preventing blockage and ensuring smooth drainage. A check valve 20 is rotatably connected to the bottom of the window frame 1 through a miniature torsion spring 21. The check valve 20 is located at the bottom of the drainage channel 22. Under normal conditions, the miniature torsion spring 21 keeps the check valve 20 closed to prevent dust, mosquitoes, and rainwater from flowing back into the drainage channel 22. When water flows out of the drainage channel 22, the water pressure can push the check valve 20 to open. After the water flows out, the miniature torsion spring 21 drives the check valve 20 to close again.

[0037] Working principle: When disassembling the screen window, when separating the window frame 1 from the mounting frame 8, manually push the trigger block 10 on the window frame 1. Its sliding part drives the rack 14 to move. The rack 14 meshes with the drive gear 15 to rotate. The bevel gear 16, which is coaxial with the gear 15, rotates synchronously, which in turn meshes with the bevel gear 19 and the coaxial gear 18 to rotate. The gear 18 then drives the rack 17 to slide, so that the locking block 11, which is fixed to the rack 17, slides along the guide rod 13 and disengages from the mounting frame 8 to achieve disassembly. During installation, simply align the window frame 1 with the mounting frame 8 and press it down. When the inclined surface on one side of the locking block 11 contacts the mounting frame 8, it automatically slides inward. After the locking block 11 is inserted into the mounting frame 8, the spring 12 releases its elastic force, pushing the locking block 11 to reset along the guide rod 13 and re-lock the window frame 1 and the mounting frame 8. During normal use, when it rains, the rainwater flows into the guide channel 22 at the bottom of the window frame 1. The top filter screen 23 blocks debris to prevent blockage. The water pressure pushes open the check valve 20 at the bottom of the guide channel 22 to drain the rainwater. After the rainwater is drained, the miniature torsion spring 21 drives the check valve 20 to reset and close, preventing dust and insects from flowing back in.

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.
