Description

Technical Field

[0001] This utility model relates to the field of silent door frame technology, and in particular to a profile for a silent door frame. Background Technology

[0002] As people's living standards improve, they have higher requirements for the quietness of their living and working environments. Traditional ordinary door frame profiles are inadequate in sound insulation, failing to meet the current demand for tranquil spaces. With the construction industry's increasing pursuit of energy conservation, environmental protection, and comfort, the optimization of the performance of doors and windows, as a crucial part of the building envelope, is paramount. Silent door frame profiles have emerged to address this issue, aiming to solve noise pollution problems. Through innovative structural design and material application, they improve sound insulation and vibration reduction performance, creating quiet and comfortable spaces for users, while also meeting the construction industry's development needs for high-performance door and window products.

[0003] Existing soundproof door frame profiles have significant shortcomings in sound insulation and structural design. Regarding sound insulation structure, their internal cavities are mostly simple structures, lacking zoned sound insulation design for different sound frequencies, and failing to fully utilize the internal space of the profile for efficient sound absorption and noise reduction. The selected sound insulation materials may have limitations in material properties, such as low sound absorption coefficient and poor durability, making it difficult to effectively block mid-to-high frequency noise, especially sharp noise. Furthermore, unscientific filling methods result in gaps or uneven distribution, significantly reducing sound insulation performance. Therefore, we propose a new soundproof door frame profile to address the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a profile for a silent door frame that can solve the obvious defects in the sound insulation and structural design of existing silent door frame profiles. In terms of sound insulation structure, their internal cavities are mostly simple structures, lacking zoned sound insulation design for different frequency sounds, and failing to fully utilize the internal space of the profile for efficient sound absorption and noise reduction. The selected sound insulation materials may have limitations in material properties, such as low sound absorption coefficient and poor durability, making it difficult to effectively block mid-to-high frequency noise, especially sharp noise. Furthermore, unscientific filling methods, resulting in gaps or uneven distribution, significantly reduce sound insulation performance.

[0006] To solve the above-mentioned technical problems, this utility model provides a profile for a silent door frame, adopting the following technical solution: it includes a main profile body, the main profile body having multiple interconnected chamber structures with different functions, thereby optimizing the performance of the door frame in terms of sound insulation, vibration reduction, and ease of installation. The vibration reduction chamber is elongated and extends along the length of the main profile body. A vibration reduction component with a "[" shaped structure is installed in the vibration reduction chamber. The vibration reduction component mainly consists of two secondary support legs, a vibration reduction buffer plate, and a main support leg. The two secondary support legs are firmly supported against the inner side of the door panel facing the interior of the door frame. By closely fitting with the door panel, they effectively absorb and disperse the energy generated by external vibrations of the door panel.

[0007] Optionally, a shock-absorbing buffer plate is provided on the left side of the two secondary support legs. As the core component for energy conversion and buffering, the shock-absorbing buffer plate can further disperse and buffer the vibration energy transmitted from the secondary support legs. A main support leg is provided in the middle of the left side of the shock-absorbing buffer plate. The other end of the main support leg is supported on the right side wall of the first sound insulation cavity, thereby establishing a stable mechanical connection between the shock-absorbing cavity and the first sound insulation cavity, ensuring the stability of the entire shock-absorbing structure.

[0008] Optionally, a first sound insulation cavity is provided on the left side of the shock absorption cavity. The first sound insulation cavity has the largest volume among all the cavity structures of the main profile. Its internal space is designed to be filled with high-efficiency sound insulation materials such as sound-absorbing cotton and sound insulation foam to achieve efficient sound blocking and absorption.

[0009] Optionally, a fitting installation cavity is provided on the front side of the first sound insulation cavity, the volume of which is about half that of the first sound insulation cavity. A second sound insulation cavity is provided on the right side of the fitting installation cavity, the second sound insulation cavity being the smallest in volume among all the cavities, and its interior can also be filled with sound insulation material.

[0010] Optionally, it also includes an L-shaped corner bracket connector, the outer periphery of which is provided with a positioning slot adapted to the internal shape of the accessory mounting cavity, and a rectangular folded edge mounting plate is provided inside the main profile at the transition point, the folded edge mounting plate being connected to the main profile only on one side.

[0011] Optionally, the L-shaped corner bracket connector has two fastening grooves at a 45-degree angle, the size of which matches the folded mounting plate. The L-shaped corner bracket connector and the main profile body also have two mutually perpendicular fastening slots.

[0012] Optionally, a first sealing strip mounting groove for installing a sound insulation and noise reduction sealing strip is provided on the outer side of the main profile behind the second sound insulation cavity. A second sealing strip mounting groove, perpendicular to the first sealing strip mounting groove and also used for installing a sound insulation and noise reduction sealing strip, is also provided on one side of the first sealing strip mounting groove. In addition, two decorative frame positioning grooves for installing door frame decorative frames to further enhance the decorative effect are provided on the outer left side of the main profile.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By setting up interconnected chamber structures inside the main profile, such as a first sound insulation chamber with the largest volume on the left side of the shock-absorbing chamber, filled with high-efficiency sound insulation materials such as sound-absorbing cotton and sound-insulating foam, and a second sound insulation chamber that can be filled with sound insulation materials on the right side of the accessory installation chamber, and simultaneously installing shock-absorbing components in the shock-absorbing chamber to reduce noise generated by vibration, the sound insulation performance of the door frame is significantly improved. This effectively blocks various external noises from entering the room, whether it is traffic noise, neighborhood noise, or natural environmental noise, all of which can be efficiently isolated, creating a quiet and comfortable indoor acoustic environment for users.

[0014] 2. By installing first and second sealing strip mounting grooves on the outer side of the main profile behind the second sound insulation cavity, sound insulation and noise reduction sealing strips are installed.

Furthermore, L-shaped corner brackets and folded edge mounting plates are used to stabilize the door frame structure and reduce noise caused by looseness. This achieves the goal of further enhancing sound insulation and optimizing quietness, effectively blocking noise transmission paths and eliminating noise problems caused by poor sealing and structural looseness, ensuring a consistently quiet indoor environment.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, to address the significant deficiencies in sound insulation and structural design of existing silent door frame profiles, this invention discloses a silent door frame profile. Regarding sound insulation structure, the internal cavities are often simple in construction, lacking zoned sound insulation design for different sound frequencies, and failing to fully utilize the internal space of the profile for efficient sound absorption and noise reduction. The selected sound insulation materials may have limitations in material properties, such as low sound absorption coefficient and poor durability, making it difficult to effectively block mid-to-high frequency noise, especially sharp noise. Furthermore, the filling method is often unscientific, resulting in gaps or uneven distribution, significantly reducing sound insulation performance.

[0023] The frame includes a main profile, which contains multiple interconnected chambers with different functions. This optimizes the door frame's performance in terms of sound insulation, vibration damping, and ease of installation. The vibration damping chamber is elongated, extending along the length of the main profile. Inside the chamber are vibration damping components with a "[" shaped structure. These components consist of two secondary support legs, a damping buffer plate, and a main support leg. The two secondary support legs firmly abut against the inner side of the door panel facing inwards, effectively absorbing and dispersing the energy generated by external vibrations through close contact with the door panel. This is achieved by incorporating multiple functional chambers within the main profile. The structure comprises interconnected chambers, in which a shock-absorbing component consisting of two secondary support legs, a shock-absorbing buffer plate, and a main support leg is installed within a long, narrow shock-absorbing chamber extending along the length of the main profile. The two secondary support legs are firmly supported against the inner side of the door panel facing the interior of the door frame, ensuring a tight fit between them. This effectively absorbs and disperses the energy generated by external vibrations in the door panel, optimizing the door frame's shock-absorbing performance. This enhances the door frame's stability and reduces the impact of external vibrations on the door. Furthermore, the coordinated structure of each chamber further improves the door frame's sound insulation and ease of installation.

[0024] A shock-absorbing buffer plate is installed on the left side of the two secondary support legs. As the core component for energy conversion and buffering, the shock-absorbing buffer plate can further disperse and buffer the vibration energy transmitted from the secondary support legs. A main support leg is located in the middle of the left side of the shock-absorbing buffer plate. The other end of the main support leg is supported on the right side wall of the first sound insulation cavity, thereby establishing a stable mechanical connection between the shock-absorbing cavity and the first sound insulation cavity, ensuring the stability of the entire shock-absorbing structure. By setting a shock-absorbing buffer plate on the left side of the two secondary support legs, and using it as the core component for energy conversion and buffering, the vibration energy transmitted from the secondary support legs is further dispersed and buffered. The main support leg is located in the middle of the left side of the shock-absorbing buffer plate, and its other end is supported on the right side wall of the first sound insulation cavity, establishing a stable mechanical connection between the shock-absorbing cavity and the first sound insulation cavity, the purpose of ensuring the stability of the entire shock-absorbing structure is achieved. This enables the shock-absorbing system to work stably for a long time, effectively cope with various vibrations, and comprehensively improve the shock absorption performance of the door frame.

[0025] The first sound insulation cavity is located on the left side of the damping cavity. The first sound insulation cavity has the largest volume among all the chamber structures of the main profile. Its internal space is designed to be filled with high-efficiency sound insulation materials such as sound-absorbing cotton and sound insulation foam to achieve efficient sound blocking and absorption. By setting the first sound insulation cavity with the largest volume on the left side of the damping cavity and designing its internal space to be filled with high-efficiency sound insulation materials such as sound-absorbing cotton and sound insulation foam, the sound insulation performance of the door frame is optimized, and the effect of effectively blocking external sound from entering the room is achieved, creating a quiet and comfortable acoustic environment for the room.

[0026] A component installation cavity is located at the front of the first soundproofing cavity, with a volume approximately half that of the first soundproofing cavity. A second soundproofing cavity, the smallest of all the cavities, is located to the right of the component installation cavity. This second soundproofing cavity can also be filled with soundproofing material. By setting a component installation cavity, with a volume approximately half that of the first soundproofing cavity, at the front of the first soundproofing cavity, various door locks, hinges, and other door accessories can be installed, facilitating the assembly of the door frame and improving installation convenience. At the same time, by setting the smallest second soundproofing cavity to the right of the component installation cavity and filling it with soundproofing material, the overall soundproofing effect of the door frame is further enhanced, thus comprehensively improving the performance of the door frame.

[0027] It also includes L-shaped corner bracket connectors. The outer periphery of the L-shaped corner bracket connectors is provided with positioning slots that are adapted to the internal shape of the accessory installation cavity. A rectangular folded edge mounting plate is provided inside the main profile at the transition point. The folded edge mounting plate is connected to the main profile only on one side. By equipping the L-shaped corner bracket connectors and providing positioning slots that are adapted to the internal shape of the accessory installation cavity on their outer periphery, and by providing a rectangular folded edge mounting plate that is connected to the main profile only on one side at the transition point inside the main profile, the purpose of firmly connecting the various parts of the main profile is achieved. This enhances the structural strength and stability of the door frame and ensures that the door frame is not easily deformed or disintegrated during long-term use.

[0028] The L-shaped corner bracket connector has two 45-degree inclined fastening grooves, the size of which matches the folded edge mounting plate. The L-shaped corner bracket connector and the main profile also have two mutually perpendicular fastening slots. By creating two 45-degree inclined fastening grooves on the L-shaped corner bracket connector that match the size of the folded edge mounting plate, and by setting two mutually perpendicular fastening slots on the L-shaped corner bracket connector and the main profile, the tightness of the connection between the L-shaped corner bracket connector and the main profile is improved. This enhances the overall structural stability of the door frame, enabling it to withstand greater external forces and extend its service life.

[0029] The outer side of the main profile behind the second sound insulation cavity is provided with a first sealing strip mounting groove for installing a sound insulation and noise reduction sealing strip. A second sealing strip mounting groove, perpendicular to the first, is also provided on one side of the first sealing strip mounting groove. Additionally, on the outer left side of the main profile, there are two decorative frame positioning grooves for installing door frame decorative frames to further enhance the decorative effect. By providing the first sealing strip mounting groove on the outer side of the main profile behind the second sound insulation cavity, and the second sealing strip mounting groove perpendicular to it on one side, the sealing and sound insulation effects of the door frame are enhanced, effectively blocking external noise, dust, and airflow, creating a quiet and comfortable indoor environment. Simultaneously, the two decorative frame positioning grooves on the outer left side of the main profile for installing door frame decorative frames further enhance the decorative effect of the door frame and improve the overall aesthetics of the home.

[0030] L-shaped corner bracket connector installation steps: Before installation, confirm that the L-shaped corner bracket connector is compatible with the main profile and check the fit between the positioning slot and the accessory mounting cavity. During installation, accurately place the L-shaped corner bracket connector at the corresponding position on the main profile, ensuring a tight fit between the positioning slot and the accessory mounting cavity. Next, push the rectangular folded edge mounting plate, originally parallel to the main profile, towards the 45-degree inclined fastening groove on the L-shaped corner bracket connector. During this pushing process, constantly monitor the angle change between the folded edge mounting plate and the fastening groove. Continue until the folded edge mounting plate is parallel to the fastening groove. Once parallel, use the appropriate bolts to tighten the L-shaped corner bracket connector through the perpendicular fastening slots on the main profile. This step effectively strengthens the door frame structure, ensuring its stability during long-term use and preventing deformation and loosening caused by unstable connections.

[0031] The specific working principle is as follows: Interconnected chamber structures are set within the main profile. For example, a first sound insulation chamber with the largest volume is located on the left side of the damping chamber, filled with high-efficiency sound insulation materials such as sound-absorbing cotton and sound-insulating foam. A second sound insulation chamber, which can be filled with sound insulation materials, is located on the right side of the accessory installation chamber. Simultaneously, damping components are installed within the damping chamber to reduce noise generated by vibration. This significantly improves the sound insulation performance of the door frame, effectively blocking various types of external noise from entering the room, including traffic noise, neighborhood noise, and natural environmental noise, creating a quiet and comfortable indoor acoustic environment for users. First and second sealing strip installation grooves are set on the outer side of the main profile behind the second sound insulation chamber for installing sound-insulating and noise-reducing sealing strips. These, along with the decorative frame positioning groove on the outer left side of the main profile, reduce sound leakage through gaps. Furthermore, L-shaped corner bracket connectors and folded edge mounting plates are used to stabilize the door frame structure and reduce noise caused by loosening. This achieves the goal of further enhancing sound insulation and optimizing noise reduction performance, effectively blocking noise transmission paths in all directions, eliminating noise problems caused by poor sealing and loose structure, and ensuring a consistently quiet indoor environment.

[0032] 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 included within the scope of protection of this utility model.
