Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic sliding door and window technology, and in particular to a sound-insulating and noise-reducing energy-saving aluminum-plastic sliding door and window. Background Technology

[0002] Aluminum-plastic sliding doors and windows are a type of door and window made primarily of aluminum alloy and plastic. Their core feature is the sliding mechanism that allows the door or window sash to be opened and closed. These doors and windows typically use aluminum alloy profiles as the main frame, offering advantages such as high strength and resistance to deformation. A plastic layer is also laminated inside or on the surface of the profiles to enhance heat insulation, sound insulation, and reduce heat conduction. They are widely used in residential and office buildings to meet the lighting and ventilation needs of modern architecture, making them a practical and economical choice for modern buildings.

[0003] Chinese patent application CN221032206U discloses an energy-saving aluminum-plastic sliding door and window, including a sliding window shell, a guide rail, and a guide rail base. The sliding window shell has a sliding groove inside, with a rotating groove in the middle. A gear shaft fixing pin is fixedly connected to the right end of the rotating groove, and a gear shaft is rotatably connected to the left end of the gear shaft fixing pin. A handle is fixedly connected to the left end of the gear shaft, and a fixing block is fixedly connected to the right end of the handle. A toothed plate is meshed with the gear shaft, and a connecting rod is fixedly connected to the lower end of the toothed plate. A convenient mounting block is fixedly connected to the lower end of the connecting rod. A convenient mounting block groove is provided on the lower outer side of the sliding window shell, and a roller is fixedly connected to the inner side of the middle of the convenient mounting block. A guide rail is slidably connected to the lower end of the roller, and a guide rail base is fixedly connected to the lower end of the guide rail. This energy-saving aluminum-plastic sliding door and window allows for convenient disassembly and assembly, reducing the risk of damage during disassembly and assembly.

[0004] Although this patent has the advantage of easy disassembly of sliding doors and windows, which can reduce the risk of damage to doors and windows during disassembly and assembly, and uses a handle to drive the gear shaft to rotate, thereby enabling the gear plate, connecting rod, and installation block to work together to separate or install the door / window from the guide rail, this patent has shortcomings in terms of sealing, sound insulation, and energy saving. Relying solely on the cooperation between rollers and guide rails, it is difficult to form a tight sealing structure, resulting in poor sealing of doors and windows, failing to effectively block air infiltration and heat exchange, and significantly reducing the sound insulation effect.

[0005] Therefore, those skilled in the art have provided a sound-insulating and noise-reducing energy-saving aluminum-plastic sliding door and window to solve the problems mentioned in the background art. Utility Model Content

[0006] In order to improve the poor sealing performance of traditional soundproof and noise-reducing energy-saving aluminum-plastic sliding doors and windows, this utility model provides a soundproof and noise-reducing energy-saving aluminum-plastic sliding door and window.

[0007] This utility model provides a soundproof and noise-reducing energy-saving aluminum-plastic sliding door and window, which adopts the following technical solution:

[0008] A soundproof and noise-reducing energy-saving aluminum-plastic sliding door and window includes a frame. A locking mechanism is fixedly connected to one side of the frame, and a door / window body is movably connected to the inner wall of the frame. The locking mechanism includes an embedded shell, one side of which is fixedly connected to the frame. A motor is fixedly connected to the inner wall of the embedded shell. Threaded rods are fixedly connected to both ends of the motor. A movable sleeve is threaded onto the surface of the threaded rod. A first pressing block is fixedly connected to one side of the movable sleeve. One side of the first pressing block extends to the outside of the frame. A second pressing block is fixedly connected to the surface of the door / window body. The first pressing block contacts the second pressing block. A pressing sealing structure is fixedly connected to the inner wall of the frame.

[0009] Optionally, a limiting block is fixedly connected to the surface of the movable sleeve, and a limiting groove is provided on the inner wall of the embedded shell to cooperate with the limiting block.

[0010] Optionally, a limiting rod is fixedly connected to the inner wall of the embedded shell, a limiting sleeve is slidably connected to the surface of the limiting rod, the top of the limiting sleeve is fixedly connected to the first extrusion block, a spring is sleeved on the surface of the limiting rod, one end of the spring is fixedly connected to the inner wall of the embedded shell, and the other end of the spring is fixedly connected to the limiting sleeve.

[0011] Optionally, the compression sealing structure includes a fixed shell, the bottom of which is fixedly connected to the inner wall of the frame, and a sealing ring is fixedly connected to the inner wall of the fixed shell, the back of which contacts the door / window body.

[0012] Optionally, a handle is fixedly connected to the back of the door / window body, and the surface of the handle is provided with anti-slip texture.

[0013] Optionally, the door and window body includes a door and window frame, and vacuum laminated glass is fixedly connected to the inner wall of the door and window frame. One side of the door and window frame is movably connected to the frame body via a hinge.

[0014] Optionally, the end of the threaded rod away from the motor is movably connected to the inner wall of the embedded shell via a bearing, and a movable opening for use with the first extrusion block is provided on one side of the embedded shell.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. In terms of locking and sealing, this utility model achieves efficient sealing through the coordinated action of multiple components. The motor drives the threaded rod to rotate, causing the moving sleeve to move towards each other and push the first extrusion block to extend. The first extrusion block contacts and extrudes the second extrusion block, driving the door and window body closer to the extrusion sealing structure until it is tightly pressed. This mechanically driven locking method, compared with traditional manual locking, can provide more uniform and stable extrusion force, ensuring that the door and window body and the sealing ring are fully fitted, effectively blocking air infiltration, which not only improves the sealing performance of the door and window, but also reduces heat exchange.

[0017] 2. In terms of sound insulation, noise reduction, and energy saving, the tight sealing structure and the design of the door and window body play a key role. The tight fit between the door and window body and the sealing ring in the fixed shell can effectively block outdoor noise from entering the room through gaps. The vacuum laminated glass inside the door and window body, by utilizing the characteristics of the vacuum layer and the laminated layer, further weakens the transmission of sound and greatly improves the sound insulation effect. At the same time, the good sealing performance reduces the convection of indoor and outdoor air, reducing the energy consumption loss of air conditioning or heating. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] Example 1:

[0027] Please refer to Figure 1-5A soundproof and noise-reducing energy-saving aluminum-plastic sliding door and window includes a frame 1, a locking mechanism 2 fixedly connected to one side of the frame 1, and a door and window body 3 movably connected to the inner wall of the frame 1. The locking mechanism 2 includes a pre-embedded shell 21, one side of which is fixedly connected to the frame 1, and a motor 22 fixedly connected to the inner wall of the pre-embedded shell 21. Threaded rods 23 are fixedly connected to both ends of the motor 22. A movable sleeve 24 is threadedly connected to the surface of the threaded rod 23. A first pressing block 25 is fixedly connected to one side of the movable sleeve 24. One side of the first pressing block 25 extends to the outside of the frame 1. A second pressing block 26 is fixedly connected to the surface of the door and window body 3. The first pressing block 25 contacts the second pressing block 26. A pressing sealing structure 27 is fixedly connected to the inner wall of the frame 1.

[0028] In this embodiment: the pre-embedded shell 21 is fixed to the frame 1, the motor 22 drives the threaded rod 23 to rotate, causing the moving sleeve 24 to drive the first extrusion block 25 to extend and contact and extrude with the second extrusion block 26 of the door and window body 3, so that the door and window body 3 and the extrusion sealing structure 27 of the frame 1 are tightly fitted. The extrusion sealing structure 27 enhances the sealing performance when the door and window are closed and reduces gaps. The electric locking combined with the sealing structure controls the gaps when the door and window are closed. Compared with the traditional manual locking, it effectively improves the airtightness. The double extrusion design combined with the sealing structure effectively blocks external noise and reduces heat exchange.

[0029] Example 2:

[0030] Reference Figure 1-5 A limiting block is fixedly connected to the surface of the movable sleeve 24. A limiting groove for use with the limiting block is opened on the inner wall of the embedded shell 21. A limiting rod 4 is fixedly connected to the inner wall of the embedded shell 21. A limiting sleeve 5 is slidably connected to the surface of the limiting rod 4. The top of the limiting sleeve 5 is fixedly connected to the first extrusion block 25. A spring 6 is sleeved on the surface of the limiting rod 4. One end of the spring 6 is fixedly connected to the inner wall of the embedded shell 21. The other end of the spring 6 is fixedly connected to the limiting sleeve 5. The extrusion sealing structure 27 includes a fixed shell 271. The bottom of the fixed shell 271 is fixedly connected to the inner wall of the frame 1. A sealing ring 272 is fixedly connected to the inner wall of the shell 271. The back of the sealing ring 272 contacts the door and window body 3. A handle is fixedly connected to the back of the door and window body 3. The surface of the handle is provided with anti-slip texture. The door and window body 3 includes a door and window frame 31. Vacuum laminated glass 32 is fixedly connected to the inner wall of the door and window frame 31. One side of the door and window frame 31 is movably connected to the frame 1 through a hinge. The end of the threaded rod 23 away from the motor 22 is movably connected to the inner wall of the embedded shell 21 through a bearing. A movable opening for use with the first extrusion block 25 is opened on one side of the embedded shell 21.

[0031] In this embodiment: the limiting block slides along the limiting groove on the inner wall of the pre-embedded shell 21, constraining the movement trajectory of the moving sleeve 24 and preventing it from rotating or deviating under the drive of the threaded rod 23, ensuring that the first extrusion block 25 moves smoothly along a straight line with uniform extrusion force, avoiding deformation of the door and window body 3 due to uneven force. The limiting rod 4 slides with the limiting sleeve 5 to provide vertical support for the first extrusion block 25. The spring 6 compresses and stores force when the first extrusion block 25 extends and releases elastic force to assist in reset when it retracts. The fixed shell 271 of the extrusion sealing structure 27 is fixed to... The frame 1 and the sealing ring 272 are deformed by the door and window body 3 when the door and window are closed, filling the gaps to form a sealing barrier. The handle on the back of the door and window body 3 makes it easy to push and pull the door and window manually. The anti-slip texture increases the grip friction and prevents the hand from slipping during operation. The door and window frame 31 of the door and window body 3 serves as a supporting structure. The vacuum laminated glass 32 blocks noise and heat. The hinge connection realizes the opening and closing rotation of the door and window. The threaded rod 23 is connected to the inner wall of the pre-embedded shell 21 through the bearing to reduce the rotation resistance. The movable opening provides a channel for the extension and retraction of the first extrusion block 25 and avoids structural interference.

[0032] The implementation principle of this utility model is as follows: When it is necessary to close the door and window, the handle is used to push the door and window body 3 to move along the inner wall of the frame 1 to the closed position, and the locking mechanism 2 is activated. The motor 22 drives the threaded rods 23 at both ends to rotate. The threaded rods 23 drive the moving sleeves 24 to move towards each other. The moving sleeves 24 apply a pushing force to the first pressing block 25, causing the first pressing block 25 to extend along the moving opening of the pre-embedded shell 21. After the first pressing block 25 extends, it contacts and presses the second pressing block 26 on the surface of the door and window body 3. The second pressing block 26 is forced to move the door and window body 3 closer to the surface of the fixed shell 271 until the back of the door and window body 3 is in contact with the fixed shell 271. The sealing ring 272 is tightly pressed to achieve a seal. During this process, the limiting sleeve 5 at the top of the first extrusion block 25 slides along the limiting rod 4, while the spring 6 is compressed to deform and store force, ensuring a smooth extrusion process. When it is necessary to open the door and window, the starting motor 22 reverses and drives the threaded rod 23 to rotate in the opposite direction. The moving sleeve 24 resets and no longer compresses the first extrusion block 25. The spring 6 releases its elastic potential energy to push the limiting sleeve 5 and the first extrusion block 25 back. The first extrusion block 25 separates from the second extrusion block 26. The door and window body 3 can be opened by pulling the handle. The vacuum laminated glass 32 inside the door and window body 3, together with the sealing ring 272, effectively improves the sound insulation and noise reduction effect.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
