Description

Technical Field

[0001] This invention relates to the field of security door technology, specifically to a high-noise-reduction security door. Background Technology

[0002] With the development of modern society, security doors have become an important component of building security and have been widely used. Traditional security doors mainly provide physical barriers and anti-theft functions, and are usually made of steel or other high-strength materials to ensure good resistance to damage. However, as people's demands for quality of life continue to rise, the single function of anti-theft can no longer meet the needs of users. The multi-functionality of security doors has gradually become the focus of attention, especially in terms of noise reduction and fire resistance.

[0003] While existing security doors have significantly improved in terms of anti-theft performance, they still have some shortcomings in terms of noise reduction and fire resistance.

[0004] Insufficient noise reduction performance:

[0005] Single material application: Many traditional security doors use only steel or other single materials. Although such materials have a certain barrier effect, their ability to absorb and reflect sound is limited, and they cannot effectively reduce the impact of outdoor noise on the indoor environment.

[0006] Simple structural design: The internal structure of existing security doors is relatively simple, lacking specially designed noise reduction layers and sound-absorbing materials, resulting in poor overall noise reduction performance and difficulty in meeting users' needs for a quiet environment.

[0007] To address the shortcomings of existing technologies, this invention proposes a high-noise-reduction security door. Through the innovative application of multi-layered noise-reducing and sound-insulating cores and high-quality materials, it solves many problems related to noise reduction and sealing performance in existing security doors. Specifically, this invention significantly improves the overall performance of the security door by incorporating a multi-layered noise-reducing and sound-insulating core, including multiple noise-reducing layers, as well as a cleverly designed reflector and sound-absorbing cavity, providing a quieter, safer, and more comfortable living and working environment.

[0008] This high-noise-reduction security door not only possesses excellent physical protection capabilities, but also achieves outstanding noise reduction effects through a multi-layered structural design and the application of highly efficient sound-absorbing materials. Furthermore, the high-quality sealing strip design on the outer frame of the door further enhances its sealing performance, preventing noise and dust from entering the room and ensuring a clean indoor environment. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, the purpose of this invention is to provide a high-noise-reduction security door.

[0010] To achieve the aforementioned objective, the technical solution of the present invention is as follows: a high noise reduction security door, comprising a door body and a sealing plate enclosed on its inner end face, wherein a noise reduction and sound insulation core is provided inside the door body;

[0011] The noise reduction and sound insulation core specifically includes the following structure:

[0012] A flame-retardant layer distributed inside the door body at a location away from the sealing plate;

[0013] A first noise reduction layer distributed inside the flame-retardant layer;

[0014] A second noise reduction layer is distributed inside the first noise reduction layer;

[0015] A third noise reduction layer is distributed inside the second noise reduction layer;

[0016] The first noise reduction layer specifically includes the following structure:

[0017] As the first fixing plate of the external structure;

[0018] The first sound-absorbing cavity is distributed inside the first fixed plate;

[0019] A first wave-shaped reflector is vertically distributed within the first sound-absorbing cavity;

[0020] The second noise reduction layer specifically includes the following structure:

[0021] As a second fixing plate of the external structure;

[0022] The second sound-absorbing cavity is distributed inside the second fixed plate;

[0023] A second wave-shaped reflector is distributed laterally inside the second sound-absorbing cavity.

[0024] As a preferred technical solution of the invention, the first wave-shaped reflector is provided with a number of vertically distributed first sound-absorbing perforations evenly arranged inside.

[0025] The second wave-shaped reflector has several horizontally distributed second sound-absorbing perforations evenly arranged inside.

[0026] As a preferred embodiment of the invention, the internal hole shape of the first sound-absorbing perforation and the second sound-absorbing perforation is set to a regular hexagon.

[0027] As a preferred embodiment of the invention, the flame-retardant layer is made of silicate board material.

[0028] As a preferred embodiment of the invention, both the first fixing plate and the first wave-shaped reflector are made of polyester fiber.

[0029] As a preferred embodiment of the invention, both the second fixing plate and the second corrugated reflector are made of polyester fiber.

[0030] As a preferred technical solution of the invention, the second noise reduction layer is made of poplar wood fiber as raw material, combined with inorganic hard cement adhesive, and manufactured under high temperature and high pressure conditions using a continuous operation process.

[0031] As a preferred embodiment of the invention, a plurality of third sound-absorbing perforations are uniformly formed on the second noise reduction layer perpendicular to the plane of the second noise reduction layer, and the internal shape of the third sound-absorbing perforations is set as a regular hexagon.

[0032] As a preferred embodiment of the invention, both the door body and the sealing plate are made of stainless steel.

[0033] As a preferred embodiment of the invention, three sealing strips are provided on the outer frame of the door.

[0034] The beneficial effects of this invention are reflected in:

[0035] Excellent noise reduction performance:

[0036] Multi-layer noise reduction design: The door body is equipped with multiple layers of noise reduction and sound insulation cores, including a flame-retardant layer, a first noise reduction layer, a second noise reduction layer, and a third noise reduction layer. Each layer is carefully designed to absorb and reflect sound waves to the maximum extent and reduce noise transmission.

[0037] The first noise reduction layer consists of a first fixing plate made of polyester fiber, a closed first sound-absorbing cavity, a wave-shaped reflector, and vertically distributed sound-absorbing perforations, which can effectively increase the propagation path of sound waves and the sound absorption efficiency, and significantly reduce noise.

[0038] The second noise reduction layer combines poplar wood fiber and inorganic hard cement adhesive, which has excellent sound absorption performance and further enhances the sound absorption effect through hexagonal sound-absorbing perforations.

[0039] The third noise reduction layer further reflects, scatters, and absorbs sound waves through the second fixed plate, the closed second sound-absorbing cavity, and the horizontally distributed wave-shaped reflector and sound-absorbing perforations, so as to effectively reduce the remaining noise.

[0040] Sealing strip design: Three high-quality rubber sealing strips are installed on the outer frame of the door, which can effectively seal the gap between the door and the door frame, prevent noise and dust from entering the room, and further improve the noise reduction effect and the cleanliness of the indoor environment.

[0041] This invention's high-noise-reduction security door achieves significant noise reduction through the application of multi-layered noise-reducing and sound-insulating cores and high-quality materials. The multi-layered structural design within the door not only efficiently absorbs and reflects noise but also provides excellent mechanical strength and durability. The use of external stainless steel materials and sealing strips further enhances the security effect and environmental cleanliness, resulting in a significant improvement in overall performance and providing users with a quieter, safer, and more comfortable living and working environment.

[0063] Please refer to the instruction manual appendix. Figures 1-8 This invention provides a high-noise-reduction security door, comprising a door body 1 and a sealing plate 2 enclosed on its inner end face. The door body 1 is provided with a noise-reducing and sound-insulating core 3, which is composed of multiple noise-reducing layers and flame-retardant layers, and can significantly improve the sound insulation effect and fire resistance of the door body.

[0064] The specific structure of noise reduction and sound insulation core 3:

[0065] Flame retardant layer 31:

[0066] The flame-retardant layer 31 is distributed inside the door body 1, located away from the sealing plate 2, and is made of silicate board. Silicate board not only has excellent flame-retardant properties but also good mechanical strength and durability. By setting the flame-retardant layer, the security door can effectively delay the spread of fire in the event of a fire, increasing the time for people to escape and extinguish the fire.

[0067] First noise reduction layer 32:

[0068] The first noise reduction layer 32 is located inside the flame retardant layer 31 and includes the following structure:

[0069] First fixing plate 321: As an external structure, it is made of polyester fiber. Polyester fiber is lightweight, high-strength, and has good sound absorption properties, which can effectively support the internal structure and improve the overall noise reduction effect.

[0070] First sound-absorbing cavity 322: Distributed inside the first fixed plate 321, this cavity is designed as a closed structure with an internal cavity, which can absorb and reduce the sound transmission through the door and enhance the noise reduction effect.

[0071] The first wave-shaped reflector 323 is vertically distributed within the first sound-absorbing cavity 322. Made of polyester fiber, it features a wave-shaped structure with several vertically distributed first sound-absorbing perforations 3231 evenly distributed inside. The wave-shaped structure effectively reflects and scatters sound waves, increasing the sound wave propagation path and thus improving sound absorption efficiency. The perforations are hexagonal in shape, which further disperses sound waves and enhances noise reduction.

[0072] Second noise reduction layer 33:

[0073] The second noise reduction layer 33 is located inside the first noise reduction layer 32. It is made from poplar wood fiber and combined with inorganic hard cement adhesive through a continuous process under high temperature and high pressure. Poplar wood fiber has excellent sound absorption properties, while the inorganic hard cement adhesive provides a strong structural support, giving this layer both sound absorption and structural strength. Several third sound-absorbing perforations 331 are uniformly formed perpendicular to the plane on this layer. These perforations are hexagonal in shape, which further increases the sound-absorbing surface area and sound absorption effect.

[0074] Third noise reduction layer 34:

[0075] The third noise reduction layer 34 is located inside the second noise reduction layer 33 and includes the following structure:

[0076] Second fixing plate 341: As an external structure, it is made of polyester fiber. Similar to the first fixing plate, the second fixing plate is lightweight and high-strength, and can effectively support the internal structure.

[0077] The second sound-absorbing cavity 342 is located inside the second fixed plate 341 and is designed as a closed structure. It has a good sound absorption effect and can effectively reduce noise passing through the door.

[0078] The second wave-shaped reflector 343 is distributed laterally inside the second sound-absorbing cavity 342. It is made of polyester fiber and designed with a wave-shaped structure. Several laterally distributed second sound-absorbing perforations 3431 are evenly arranged inside. Similar to the first wave-shaped reflector, the wave-shaped structure and the design of the sound-absorbing perforations can effectively reflect and scatter sound waves, improve sound absorption efficiency, and reduce noise transmission.

[0079] The sound wave absorption and attenuation process when external sound waves reach the inside of the door:

[0080] When external noise reaches the security door, the following is the process of the sound waves being absorbed and reduced layer by layer:

[0081] External sound waves reach the door surface:

[0082] External sound waves first strike the surfaces of door 1 and sealing plate 2. The stainless steel door has high density and high reflectivity, which can reflect some of the sound waves, preventing some of the sound waves from entering the interior of the door.

[0083] The sound waves penetrate the surface of the door and reach the flame-retardant layer 31.

[0084] Sound waves passing through the surface of the door enter the flame-retardant layer 31. The silicate board material has a certain density and sound absorption properties, which can absorb and block some sound waves. At the same time, its flame-retardant properties can also provide additional protection in the event of a fire.

[0085] The sound waves reach the first noise reduction layer 32:

[0086] The remaining sound waves enter the first noise reduction layer 32, first passing through the first fixing plate 321, and then entering the first sound absorption cavity 322. The closed structure and cavity design of the first sound absorption cavity can absorb and reduce the energy of the sound waves.

[0087] When the sound wave reaches the first wave-shaped reflector 323, the wave-shaped structure and the vertically distributed first sound-absorbing perforations 3231 can further reflect, scatter and absorb the sound wave, increasing the propagation path and attenuation efficiency of the sound wave.

[0088] The sound waves reach the second noise reduction layer 33:

[0089] The remaining sound waves enter the second noise reduction layer 33. The combination of poplar wood fiber and inorganic hard cement adhesive can effectively absorb the sound waves and reduce their propagation.

[0090] The third sound-absorbing perforation 331 on the second noise reduction layer further increases the sound-absorbing surface area, enabling more efficient absorption of sound waves and reducing the intensity of sound waves.

[0091] The sound waves reach the third noise reduction layer 34:

[0092] The final sound wave enters the third noise reduction layer 34, first passing through the second fixing plate 341, and then entering the second sound absorption cavity 342.

[0093] When the sound wave reaches the second wave-shaped reflector 343, the laterally distributed wave-shaped structure and the second sound-absorbing perforation 3431 can effectively reflect, scatter and absorb the remaining sound wave, further reducing the energy and intensity of the sound wave.

[0094] Material and sealing structure of door and panel:

[0095] Door body 1 and panel 2: Both are made of stainless steel. Stainless steel is characterized by high strength, corrosion resistance, and aesthetics, providing excellent anti-theft performance and a long service life. The use of stainless steel also increases the overall weight and sturdiness of the door, enhancing its anti-theft effect.

[0096] Sealing strip 11: Three sealing strips made of high-quality rubber material are installed on the outer frame of the door body 1. The sealing strips can effectively seal the gap between the door body and the door frame, preventing noise and dust from entering the room, further improving the noise reduction effect and the cleanliness of the indoor environment.
