Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window sash buffer closing technology, specifically a buffer closing device between aluminum alloy door and window sash and frame. Background Technology

[0002] In modern architecture, aluminum alloy doors and windows are widely used due to their lightweight, high strength, good sealing properties, and aesthetic appeal. The closing mechanism of aluminum alloy door and window sashes and frames is a crucial component of the door and window system, and its performance directly affects the usability, lifespan, and user experience. However, existing aluminum alloy door and window sash and frame closing mechanisms have several shortcomings in practical use.

[0003] The existing aluminum alloy door and window sashes are mostly connected to the frame through spring hinges. These elastic elements are prone to fatigue during long-term use, resulting in unstable closing force. When closing the door and window, they may not close tightly or the closing force may be too great. This not only affects the sealing performance of the door and window, but may also cause impact to the door and window frame and sash, generate noise, or even damage the door and window structure.

[0004] Therefore, a buffer closing device for aluminum alloy door and window sashes and frames is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this paper addresses the problem that the elastic elements of most existing aluminum alloy door and window sashes and frames are prone to fatigue during long-term use, leading to unstable closing force. This can result in doors and windows not closing tightly or closing with excessive force, which not only affects the sealing performance of doors and windows but may also cause impact to the door and window frames and sashes, generate noise, or even damage the door and window structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The buffer closing device for aluminum alloy door and window sash and frame of this utility model includes an aluminum alloy frame, a door and window body is slidably connected inside the aluminum alloy frame, a first magnet is fixedly connected to the side of the door and window body, a second magnet is fixedly connected to the end of the first magnet, and a buffer component is provided on the side of the second magnet; the buffer component includes a rubber pad, a groove is opened inside the rubber pad, a protrusion is engaged inside the groove, and a spring is fixedly connected to the end of the protrusion.

[0007] Preferably, the grooves are arranged at equal intervals with respect to the interior of the rubber pad, and the protrusions and grooves form an engaging structure.

[0008] Preferably, the grooves are arranged at equal intervals with respect to the interior of the rubber pad, and the protrusions and grooves form an engaging structure.

[0009] Preferably, the aluminum alloy frame is coated with an anti-oxidation layer, and the anti-oxidation layer is made of polyurethane coating.

[0010] Preferably, the door / window body and the aluminum alloy frame form a sliding structure, and the door / window body and the first magnet are integrated into one unit.

[0011] Preferably, the second magnet and the aluminum alloy frame are integrated, and the door and window body forms a magnetic attraction structure with the aluminum alloy frame through the first magnet, the second magnet, and the first magnet.

[0012] The advantages of this utility model are:

[0013] 1. This aluminum alloy door and window sash and frame buffer closure device ingeniously integrates multiple innovative elements in its structural design, achieving significant improvements in function and performance and demonstrating numerous notable advantages. Firstly, the clever design of the buffer component provides effective cushioning during the closing process of doors and windows. The interlocking structure formed by the evenly spaced grooves and protrusions inside the rubber pad, combined with the elasticity of the spring, can accurately and evenly absorb the impact force generated when the door and window close. This buffering mechanism not only significantly reduces the noise when doors and windows close, creating a quieter indoor environment, but also significantly reduces the risk of deformation of the door and window frames and sashes due to impact, thereby effectively extending the service life of the doors and windows. Furthermore, the evenly spaced grooves and protrusions ensure the uniform distribution of the buffering force, further improving the stability and reliability of the buffering effect, allowing doors and windows to maintain a smooth closing state under various usage conditions.

[0014] 2. Secondly, the magnetic attraction structure between the door / window body and the aluminum alloy frame achieves a tight closure of the door / window through the mutual attraction of the first and second magnets. This magnetic structure not only improves the sealing performance of the door / window, effectively blocking external dust, rainwater, and cold air, and enhancing the thermal insulation performance of the door / window, thus contributing to energy conservation and emission reduction, but also ensures the stability of the door / window when closed. The integrated design of the door / window body with the first magnet, and the integrated design of the second magnet with the aluminum alloy frame, further enhances the stability and durability of the magnetic structure, preventing the magnets from loosening or falling off due to long-term use, thereby ensuring the long-term stable sealing performance of the door / window.

[0015] 3. Furthermore, the polyurethane coating on the exterior of the aluminum alloy frame provides additional protection for the doors and windows. Polyurethane coating has excellent anti-oxidation, weather resistance, and corrosion resistance, effectively resisting the erosion of the aluminum alloy frame by environmental factors such as ultraviolet rays, acid rain, and salt spray, extending the service life of the aluminum alloy frame and maintaining the aesthetic appearance of the doors and windows. The application of this anti-oxidation layer not only improves the overall quality of the doors and windows but also reduces maintenance costs, making them more suitable for use in various complex environments, maintaining good performance whether in the humid and salty environments of coastal areas or in areas with severe industrial pollution.

[0016] 4. Finally, the entire buffer closure device features a rational structural design, with tight and robust connections between all components. The sliding structure design between the door / window body and the aluminum alloy frame ensures smooth opening and closing, reducing wear caused by friction. This structural design not only improves the durability of the doors and windows but also ensures stable performance during long-term use, reducing the frequency of maintenance and replacement. Furthermore, the device is simple and quick to install, requiring no complex tools or professional skills, thus reducing installation costs and time. Even when maintenance is needed, its detachable design makes maintenance more convenient, allowing users to easily replace worn parts such as rubber pads or springs, thereby extending the overall lifespan of the device.

[0024] Example 1

[0025] like Figure 1 The present invention relates to a buffer closing device for aluminum alloy door and window sash and frame, comprising an aluminum alloy frame 1, a door and window body 2, a first magnet 3, a second magnet 4, and a buffer assembly 5.

[0026] Please see Figure 1 and Figure 4 The diagram illustrates a buffer closing device for an aluminum alloy door / window sash and frame, comprising an aluminum alloy frame 1, a door / window body 2 slidably connected inside the aluminum alloy frame 1, a first magnet 3 fixedly connected to the side of the door / window body 2, a second magnet 4 fixedly connected to the end of the first magnet 3, and a buffer assembly 5 provided on the side of the second magnet 4; the buffer assembly 5 includes a rubber pad 501, a groove 502 formed inside the rubber pad 501, a protrusion 503 engaged inside the groove 502, and a spring 504 fixedly connected to the end of the protrusion 503; the groove 502 is positioned relative to the rubber pad 501. The internal components of the aluminum alloy frame 1 are arranged at equal intervals, and the protrusions 503 and the grooves 502 form an engaging structure; the grooves 502 are arranged at equal intervals about the internal components of the rubber pad 501, and the protrusions 503 and the grooves 502 form an engaging structure; the exterior of the aluminum alloy frame 1 is coated with an anti-oxidation layer, and the material of the anti-oxidation layer is set as polyurethane coating; the door and window body 2 and the aluminum alloy frame 1 form a sliding structure, and the door and window body 2 and the first magnet 3 are integrated; the second magnet 4 and the aluminum alloy frame 1 are integrated, and the door and window body 2 and the aluminum alloy frame 1 form a magnetic attraction structure through the first magnet 3 and the second magnet 4.

[0027] Working Principle: When the user pushes the door / window body 2 to close, the door / window body 2 and the aluminum alloy frame 1 form a sliding structure. The door / window body 2 will slide stably along the internal track of the aluminum alloy frame 1. The polyurethane coating material on the outside of the aluminum alloy frame 1 has an anti-oxidation layer that isolates the aluminum alloy frame 1 from external air, moisture and other corrosive media during this process, preventing oxidation and rust caused by long-term exposure or sliding friction, thus extending the service life of the entire device. As the door / window body 2 moves towards the closed position, the first magnet 3, which is integrated with the door / window body 2, will also move closer to the aluminum alloy frame 1. At this time, the second magnet 4, which is integrated with the aluminum alloy frame 1, will attract the first magnet 3 due to the magnetic attraction effect. This magnetic attraction structure can provide auxiliary traction for the closing of the door / window body 2, guiding the door / window body 2 to move accurately towards the closed position and preventing deviation during the closing process. On the other hand, the attraction force generated by the magnetic attraction will appropriately slow down the sliding speed of the door / window body 2 when it is close to being fully closed, paving the way for the subsequent buffer component 5 to play its role.

[0028] As the door / window body 2 approaches the closed position under magnetic attraction, the first magnet 3 and the second magnet 4 on its side gradually come into contact with the buffer assembly 5 located inside the aluminum alloy frame 1. The rubber pad 501 in the buffer assembly 5 first contacts the component on the side of the door / window body 2. The rubber pad 501 has a certain elastic deformation capability and can absorb part of the impact force generated by the sliding of the door / window body 2 through its own deformation, thus initially slowing down the closing speed of the door / window body 2. As the door / window body 2 continues to apply pressure, the grooves 502 arranged at equal intervals inside the rubber pad 501 will interact with the protrusions 503. Since the protrusions 503 and the grooves 502 form an interlocking structure, under pressure, the protrusions 503 will slide along the inner wall of the grooves 502. The structural design of the grooves 502 can guide and limit the sliding of the protrusions 503, preventing the protrusions 503 from shifting when subjected to force, and ensuring the stable transmission of the buffer force. At the same time, the spring 504 fixedly connected to the end of the protrusion 503 will be compressed due to the sliding of the protrusion 503. During the compression process, the spring 504 will generate a reverse elastic force, which will further offset the impact force of the door and window body 2. As the compression of the spring 504 increases, the elastic force it generates will gradually increase, thereby gradually slowing down the closing speed of the door and window body 2 and avoiding a hard collision between the door and window body 2 and the aluminum alloy frame 1.

[0029] Throughout the closing process, the door / window body 2 smoothly completes the closing action through sliding engagement with the aluminum alloy frame 1, magnetic positioning by the first magnet 3 and the second magnet 4, and the multi-stage buffering effect of the rubber pad 501, groove 502, protrusion 503, and spring 504 in the buffer assembly 5. This avoids noise and component damage during closing and ensures long-term stable operation of the device thanks to the anti-oxidation layer on the outside of the aluminum alloy frame 1. When it is necessary to open the door / window, only a pulling force greater than the magnetic attraction force needs to be applied, and the door / window body 2 will slide open along the aluminum alloy frame 1. The spring 504 in the buffer assembly 5 will return to its original state after the pressure is removed, driving the protrusion 503 back to its initial position, and the rubber pad 501 will also reset, preparing for the next closing buffer.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
