Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic doors and windows technology, and in particular to an aluminum-plastic door and window structure that is easy to disassemble and maintain. Background Technology

[0002] Aluminum-plastic composite doors and windows, also known as aluminum alloy doors and windows, are widely used in homes, hotels, high-rise buildings, etc. During the processing and production of aluminum-plastic composite doors and windows, considering that rainwater will flow into the glass along the window frame track on rainy days, drainage holes are usually set at the bottom of the window frame on the side closer to the outside. In order to prevent rainwater from flowing back in, drainage hole covers are also installed on the drainage holes.

[0003] Chinese utility model patent CN210798781U discloses an aluminum-plastic door and window, relating to the technical field of doors and windows. It includes a cover body comprising a short baffle, a long baffle, and a fixing plate. The opening of the cover body has an isolation section for blocking insects while allowing rainwater to pass through. Disassembly components are provided on the left and right sides of the isolation section to facilitate its downward removal. The isolation section includes a frame that abuts against the opening of the cover body, and a mesh screen for blocking insects while allowing rainwater to pass through is fixed to the inner circumference of the frame. This utility model reduces the disassembly and installation process of the isolation section, making it more convenient to disassemble and install.

[0004] Regarding the aforementioned technology, the inventors believe it suffers from the following drawbacks: The device blocks the drainage hole through a cover body mounted on the window frame and blocks mosquitoes through an isolation section on the cover body. When workers need to remove the isolation section, they must press the push plate and pull the frame to separate the screen from the cover body. In actual use, the connecting plate only holds the clamping plate in place by the action of a spring, thus maintaining the frame's stability. When a user accidentally touches the frame, it easily slides under external force and separates from the cover body, resulting in poor stability and a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an aluminum-plastic door and window structure that is easy to disassemble and maintain.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aluminum-plastic door and window structure that is easy to disassemble and maintain, including a window frame, a drainage hole on the side wall of the window frame, a cover body for preventing rainwater backflow on the side wall of the window frame, an elastic snap fastener fixed on the inner wall of the cover body, the other end of the elastic snap fastener passing through the drainage hole and remaining stable, T-shaped grooves on both ends of the side wall away from the window frame of the cover body, T-shaped rods slidably arranged in both T-shaped grooves, a frame installed on the bottom surface of the two T-shaped rods, a mesh screen on the inner wall of the frame, and a limiting component for limiting the T-shaped rods on the cover body.

[0007] By adopting the above technical solution, when it rains near the window frame, some rainwater may continuously impact the frame. In this case, the drainage holes reduce the probability of rainwater overflowing the frame. During this process, the screen blocks insects and other debris. After a period of use, the screen needs to be cleaned. To do this, the worker needs to close the limiting component and pull the frame, allowing the screen to move with the frame and separate from the cover body, thus reducing the difficulty of removing the screen. Furthermore, after cleaning the screen, the worker only needs to connect the T-shaped rod and T-slot and rotate the threaded rod to allow the two sliding rods to block the T-shaped rod, thus stabilizing the frame and reducing the probability of the frame separating from the cover body under external force, thereby improving the user experience.

[0008] Furthermore, a threaded groove is provided on the side wall of the cover body, and two opposing sliding grooves are provided on the inner wall of the threaded groove. The limiting component includes a sliding rod slidably disposed in the sliding groove and a threaded bar threadedly connected in the threaded groove. The two sliding grooves are respectively connected to two T-shaped grooves. A first inclined surface is provided on the edge where the side wall of the two sliding rods that are close to each other intersects with the side wall of the side wall close to the opening of the threaded groove.

[0009] Furthermore, a limiting groove is formed on the inner top wall of the slide, and a limiting block is slidably arranged in the limiting groove. The bottom surface of the limiting block is fixed to the slide rod.

[0010] Furthermore, a tension spring is fixed on the side wall of the limiting block, and the other end of the tension spring is fixed on the inner wall of the limiting groove.

[0011] By adopting the above technical solution, when workers need to inspect the mesh, they must separate the frame from the cover body. At this time, workers need to rotate the threaded rod, which moves the threaded rod towards the side closer to the threaded groove opening, gradually separating the threaded rod from the two sliding rods. After the sliding rods separate from the threaded rod, the two sliding rods move towards each other under the action of two tension springs, thus separating the two sliding rods from the two T-slots respectively. Furthermore, workers only need to pull the frame to move the mesh along with the frame and finally separate it from the cover body.

[0012] Furthermore, a stabilizing spring is fixed to the side wall of each of the two T-shaped rods, and a second inclined surface is formed on the edge of the T-shaped rod where the side wall away from the stabilizing spring intersects with the side wall near the slide rod.

[0013] By adopting the above technical solution, after the operator connects the T-shaped rod and the T-shaped groove, the operator only needs to rotate the threaded rod to move the sliding rod closer to the T-shaped rod and press it against the second inclined surface, thereby blocking the T-shaped rod. During this process, the stabilizing spring improves the tightness of the connection between the sliding rod and the T-shaped rod, thus enhancing the user experience of the device.

[0014] Furthermore, a silicone block for extending the service life of the first inclined surface is fixed on the side wall of the threaded rod.

[0015] Furthermore, a handle is fixed to the end of the threaded rod to reduce the difficulty for workers to turn the threaded rod.

[0016] Furthermore, a sealing gasket for sealing the T-shaped groove is provided inside the T-shaped groove.

[0017] By adopting the above technical solution, after the slide bar blocks the T-shaped bar, the staff only needs to connect the sealing gasket with the T-shaped groove to seal the T-shaped groove, thereby reducing the probability of impurities entering the T-shaped groove.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. In this application, when the area near the window frame is experiencing rainy weather, some rainwater may continuously impact the window frame. In this case, the drainage holes reduce the probability of rainwater overflowing the window frame. During this process, the screen blocks insects and other impurities. After a period of use, the screen needs to be cleaned. To do this, the worker needs to close the limiting component and pull the frame, allowing the screen to move with the frame and separate from the cover body, thus reducing the difficulty of removing the screen. Furthermore, after cleaning the screen, the worker only needs to connect the T-shaped rod and T-shaped groove and rotate the threaded rod to allow the two sliding rods to block the T-shaped rod, thus stabilizing the frame and reducing the probability of the frame separating from the cover body under external force, thereby improving the user experience.

[0020] 2. In this application, when workers need to inspect the mesh screen, they must separate the frame from the cover body. At this time, workers need to rotate the threaded rod, which moves the threaded rod towards the side closer to the threaded groove opening, gradually separating the threaded rod from the two sliding rods. After the sliding rods separate from the threaded rod, the two sliding rods move towards each other under the action of two tension springs, thus separating the two sliding rods from the two T-slots. Furthermore, workers only need to pull the frame to move the mesh screen along with the frame and eventually separate it from the cover body.

[0021] 3. In this application, after the operator connects the T-shaped rod and the T-shaped groove, the operator only needs to rotate the threaded rod to move the sliding rod closer to the T-shaped rod and press it against the second inclined surface, thereby blocking the T-shaped rod. During this process, the stabilizing spring improves the tightness of the connection between the sliding rod and the T-shaped rod, thus improving the user experience of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-6 As shown in the embodiment of this application, an aluminum-plastic door and window structure that is easy to disassemble and maintain is disclosed, including a window frame 1, a cover body 2, elastic snap-fit ​​parts 21, T-shaped rods 31, a frame 4, a screen 41, a limiting component 5, a limiting block 61, a tension spring 7, a stabilizing spring 71, a silicone block 8, a handle 81, and a sealing gasket 9. Drainage holes 11 are provided on the side wall of the window frame 1, and the cover body 2 is installed on the side wall of the window frame 1 to prevent rainwater backflow. Four elastic snap-fit ​​parts 21 are provided and symmetrically fixed in pairs on the inner wall of the cover body 2. The other end of the elastic snap-fit ​​parts 21 passes through the drainage holes 11 and remains stable. T-shaped grooves 3 are provided on both ends of the side wall of the cover body 2 away from the window frame 1. The T-shaped rods 31 are rod-shaped structures with a T-shaped cross-section. Two T-shaped rods 31 are provided and slidably installed in the two T-shaped grooves 3 respectively. The frame 4 is installed on the bottom surface of the two T-shaped rods 31, and the screen 41 is installed on the inner wall of the frame 4.

[0031] A threaded groove 42 is formed on the side wall of the cover body 2. Two opposing sliding grooves 43 are formed on the inner wall of the threaded groove 42. A limiting component 5 is set on the cover body 2 to limit the T-shaped rod 31. The limiting component 5 includes a sliding rod 51 and a threaded bar 52. The sliding rod 51 is a rectangular rod structure. There are two sliding rods 51, which are slidably set in the two sliding grooves 43 respectively. The threaded bar 52 is threadedly connected in the threaded groove 42. The two sliding grooves 43 are respectively connected to the two T-shaped grooves 3. A first inclined surface 53 is formed on the edge where the side wall of the two sliding rods 51 that are close to each other intersects with the side wall of the side wall that is close to the opening of the threaded groove 42.

[0032] A limiting groove 6 is formed on the inner top wall of the slide groove 43. The limiting block 61 is a rectangular block structure. The limiting block 61 is slidably disposed in the limiting groove 6, and the bottom surface of the limiting block 61 is fixed to the slide rod 51. One end of the tension spring 7 is fixed to the side wall of the limiting block 61, and the other end of the tension spring 7 is fixed to the inner wall of the limiting groove 6.

[0033] When maintenance is required on the mesh screen 41, the frame 4 must be separated from the cover body 2. To do this, the worker rotates the threaded rod, moving it closer to the opening of the threaded groove 42, gradually separating it from the two sliding rods 51. After the sliding rods 51 separate from the threaded rod, they move closer together under the action of the two tension springs 7, separating them from the two T-slots 3. Further, the worker simply pulls the frame 4, causing the mesh screen 41 to move with it and eventually separate from the cover body 2.

[0034] Two stabilizing springs 71 are provided, and one end of each stabilizing spring 71 is fixed to the side wall of two T-shaped rods 31 respectively. A second inclined surface 54 is provided on the edge of the T-shaped rod 31 where the side wall away from the stabilizing spring 71 intersects with the side wall near the slide rod 51.

[0035] After the operator connects the T-shaped rod 31 to the T-shaped groove 3, the operator only needs to rotate the threaded rod to move the slide rod 51 closer to the T-shaped rod 31 and press it against the second inclined surface 54, thereby blocking the T-shaped rod 31. During this process, the stabilizing spring 71 improves the tightness of the connection between the slide rod 51 and the T-shaped rod 31, thus improving the user experience of the device.

[0036] The silicone block 8 is a block-shaped structure and is fixed to the side wall of the threaded rod 52 to extend the service life of the first inclined surface 53. The handle 81 is fixed to the end of the threaded rod 52 to reduce the difficulty for workers to rotate the threaded rod 52.

[0037] The sealing gasket 9 is placed inside the T-groove 3 to seal the T-groove 3. When the slide rod 51 blocks the T-shaped rod 31, the operator only needs to connect the sealing gasket 9 to the T-groove 3 to seal the T-groove 3, thereby reducing the probability of impurities entering the T-groove 3.

[0038] The operating principle of this easy-to-disassemble and maintain aluminum-plastic window and door structure in this embodiment is as follows: When it is raining near the window frame 1, some rainwater may continuously impact the window frame 1. At this time, the drainage hole 11 reduces the probability of rainwater passing over the window frame 1. During this process, the screen 41 blocks mosquitoes and other impurities. After the screen 41 has been used for a period of time, the staff needs to clean it. At this time, the staff needs to close the limiting component 5 and pull the frame 4, which will allow the screen 41 to move with the frame 4 and separate from the cover body 2, thereby reducing the difficulty of removing the screen 41. Furthermore, after the staff cleans the screen 41, the staff only needs to connect the T-shaped rod 31 with the T-shaped groove 3 and rotate the threaded rod, which will allow the two sliding rods 51 to block the T-shaped rod 31, thereby keeping the frame 4 stable and reducing the probability of the frame 4 separating from the cover body 2 when subjected to external force, thus improving the user experience.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
