Description

Technical Field

[0001] The invention relates to the technical field of anti-theft doors, and in particular to a high-noise-reduction anti-theft door. Background Art

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

[0003] Although the existing anti-theft doors have significantly improved their 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 anti-theft doors only use steel or other single materials. Although this material has a certain barrier effect, its ability to absorb and reflect sound is limited, and it cannot effectively reduce the impact of outdoor noise on the indoor environment.

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

[0007] In view of the shortcomings of the above-mentioned prior art, the present invention proposes a high noise reduction anti-theft door, which solves many problems of existing anti-theft doors in terms of noise reduction and sealing performance through the innovative application of multi-layer noise reduction and sound insulation core and high-quality materials. Specifically, the present invention significantly improves the comprehensive performance of the anti-theft door by setting a multi-layer noise reduction and sound insulation core, including multiple noise reduction layers and a well-designed reflective plate and sound absorption cavity, and provides a quieter, safer and more comfortable living and working environment.

[0008] This high noise reduction anti-theft door not only has excellent physical protection capabilities, but also achieves excellent noise reduction effects through multi-layer structural design and the application of high-efficiency sound-absorbing materials. In addition, the high-quality sealing strip design on the outer frame of the door body further improves the sealing performance of the door body, preventing noise and dust from entering the room and ensuring the cleanliness of the indoor environment. Summary of the invention

[0009] In order to overcome the defects of the prior art, the object of the present invention is to provide a high noise reduction anti-theft door.

[0010] To achieve the above object, the technical solution of the present invention is implemented as follows: a high noise reduction anti-theft door, comprising a door body and a sealing plate sealed on the inner end surface thereof, wherein a noise reduction sound insulation core is arranged 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 position away from the sealing plate;

[0018] A first sound absorbing cavity distributed inside the first fixing plate;

[0019] A first wave-shaped reflective plate vertically distributed in the first sound absorbing cavity;

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

[0021] Serves as a second fixing plate for the external structure;

[0022] A second sound absorbing cavity distributed inside the second fixing plate;

[0023] A second wavy reflection plate is distributed in the second sound absorbing cavity in the transverse direction.

[0024] As a preferred technical solution of the invention, a plurality of vertically distributed first sound-absorbing perforations are evenly arranged inside the first wavy reflector;

[0025] A plurality of second sound-absorbing perforations distributed laterally are evenly arranged inside the second wavy reflective plate.

[0026] As a preferred technical solution of the invention, the internal hole shapes of the first sound-absorbing perforations and the second sound-absorbing perforations are set to be regular hexagons.

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

[0028] As a preferred technical solution of the invention, the first fixing plate and the first wavy reflecting plate are both made of polyester fiber material.

[0029] As a preferred technical solution of the invention, the second fixing plate and the second wavy reflecting plate are both made of polyester fiber material.

[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, using a continuous operation process, under high temperature and high pressure conditions.

If the specific posture changes, the directional indication will also change accordingly.

[0062] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the invention.

[0063] Please refer to the instruction manual Figure 1-Figure 8 The present invention provides a high noise reduction anti-theft door, comprising a door body 1 and a sealing plate 2 sealed on the inner end surface thereof. A noise reduction and sound insulation core 3 is arranged inside the door body 1, and the noise reduction and sound insulation core 3 is composed of multiple noise reduction layers and flame retardant layers, which can significantly improve the sound insulation effect and fire resistance of the door body.

[0064] The specific structure of the 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 material. The silicate board not only has excellent flame retardant properties, but also has good mechanical strength and durability. By setting the flame retardant layer, the anti-theft door can effectively delay the spread of fire when encountering a fire, and increase 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] The first fixing plate 321 is an external structure made of polyester fiber, which is light, high-strength and has good sound absorption performance, and can effectively support the internal structure and improve the overall noise reduction effect.

[0070] The first sound-absorbing cavity 322 is distributed inside the first fixing plate 321. The cavity is designed to be a closed structure with a hollow interior, which can absorb and reduce the sound propagation through the door body and enhance the noise reduction effect.

[0071] The first wavy reflector 323 is vertically distributed in the first sound absorption cavity 322, made of polyester fiber material, and designed into a wavy structure. A plurality of vertically distributed first sound absorption perforations 3231 are evenly arranged inside. The wavy structure can effectively reflect and scatter sound waves, increase the propagation path of sound waves, and thus improve the sound absorption efficiency. The hole shape of the first sound absorption perforation is a regular hexagon, which can better disperse sound waves and further improve the noise reduction effect.

[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 of poplar wood fiber as raw material and inorganic hard cement adhesive through continuous operation process under high temperature and high pressure conditions. Poplar wood fiber has excellent sound absorption performance, and the inorganic hard cement adhesive provides a solid structural support, so that the layer has both sound absorption and structural strength. A number of third sound absorption perforations 331 are evenly opened on the layer perpendicular to the plane. The hole shape of these perforations is a regular hexagon, which can further increase the sound absorption 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] The second fixing plate 341 is an external structure made of polyester fiber. Similar to the first fixing plate, the second fixing plate has the characteristics of light weight and high strength, and can effectively support the internal structure.

[0077] The second sound absorbing chamber 342 is distributed inside the second fixing plate 341 and is designed to be a closed structure. It has a good sound absorbing effect and can effectively reduce the noise passing through the door body.

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

[0079] The process of absorbing and reducing the sound waves from the outside that reach the inside of the door:

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

[0081] External sound waves reach the door surface:

[0082] The external sound waves first hit the surface of the door body 1 and the sealing plate 2. The stainless steel door body has high density and high reflectivity, which can reflect part of the sound waves and prevent some of the sound waves from entering the interior of the door body.

[0083] The sound waves pass through the door surface and reach the flame retardant layer 31:

[0084] The sound waves passing through the surface of the door body enter the flame retardant layer 31. The silicate board material has a certain density and sound absorption performance, which can absorb and block part of the sound waves. At the same time, its flame retardant performance 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 pass through the first fixing plate 321, and then enter 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 waves reach the first wavy reflector 323 , the wavy structure and the vertically distributed first sound-absorbing perforations 3231 can further reflect, scatter and absorb the sound waves, thereby increasing the propagation path and reduction efficiency of the sound waves.

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

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

[0090] The third sound-absorbing perforations 331 on the second noise reduction layer further increase the sound-absorbing surface area, and can absorb sound waves more efficiently and reduce the intensity of the 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 passes through the second fixing plate 341 , and then enters the second sound absorbing cavity 342 .

[0093] When the sound waves reach the second wavy reflector 343 , the laterally distributed wavy structure and the second sound-absorbing perforations 3431 can effectively reflect, scatter and absorb the remaining sound waves, further reducing the energy and intensity of the sound waves.

[0094] Door and sealing plate materials and sealing structure:

[0095] Door body 1 and cover plate 2: Both are made of stainless steel. Stainless steel has the characteristics of high strength, corrosion resistance and beauty, and can provide good anti-theft performance and long service life. The application of stainless steel can also increase the overall weight and firmness of the door body and improve the anti-theft effect.

[0096] Sealing strip 11: Three sealing strips are provided on the outer frame of the door body 1, which are made of high-quality rubber material. The sealing strip can effectively seal the gap between the door body 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.
