Description

Technical Field

[0001] This utility model relates to the technical field of dustproof communication equipment, and in particular to a dustproof box for communication transmission equipment. Background Technology

[0002] Communication transmission equipment typically includes fiber optic terminal boxes, network switches, routers, etc. These devices are easily affected by environmental factors such as dust and moisture in outdoor or industrial environments, leading to performance degradation or failure.

[0003] The related technology, with publication number CN219555336U, discloses a pressure-resistant structure for a cover plate of a communication transmission device. The structure includes a bottom box and a top box. A mounting bracket is fixed to the bottom surface of the bottom box for placing the communication transmission device. Fixing sleeves are symmetrically distributed inside the bottom box, and fixing columns are fixed within the fixing sleeves. This pressure-resistant structure incorporates a pressure-resistant component that uses a buffer spring and a compression ring to gradually release and degrade external pressure. When the top box moves downward, multiple sliding rods transfer pressure to the buffer spring through the compression ring, thus achieving efficient pressure resistance. Furthermore, a fixing column is provided inside the buffer spring to prevent deformation, facilitating long-term use of the device. A heat dissipation structure consisting of a protective cover, dustproof net, and cooling fan further enhances the practicality of the device and improves the safety protection of the communication transmission device.

[0004] The aforementioned technology uses dustproof mesh filters for dust prevention. While dustproof meshes can filter out external dust to a certain extent, they are prone to clogging due to long-term dust accumulation, leading to poor air circulation and affecting equipment heat dissipation. In addition, traditional dustproof meshes are inconvenient to replace, increasing maintenance costs. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a dustproof box for communication transmission equipment that removes the heat generated during internal operation through an efficient circulating air duct, maintaining a clean working environment and appropriate temperature, thereby ensuring the stable operation of the communication equipment and extending its service life.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a dustproof box for communication transmission equipment, including a dustproof box, a sealing cover plate disposed at the opening of the dustproof box, a connecting component disposed between the sealing cover plate and the dustproof box, an air inlet disposed on the upper end face of the dustproof box, a filter component disposed in the air inlet, an axial flow fan disposed on the lower end face of the dustproof box and disposed relative to the air inlet, and dustproof heat dissipation vents respectively disposed on both sides of the dustproof box.

[0007] By adopting the above technical solution, the heat generated during internal operation is removed through an efficient circulating air duct, maintaining a clean working environment and appropriate temperature, thereby ensuring the stable operation of communication equipment and extending its service life.

[0008] As a preferred embodiment, the connecting assembly includes mounting plates respectively disposed on the outer periphery of the opening end of the dustproof box, mounting holes evenly disposed at the four corners of the sealing cover, and fixing pins that pass through the mounting holes and connect to the mounting plates. The mounting plates are provided with pin holes that are adapted to the fixing pins.

[0009] By adopting the above technical solution, the fixing pins pass through the mounting holes of the sealing cover and the pin holes of the mounting plate in sequence, and form a tight connection by tightening, ensuring that the sealing cover can be firmly installed on the dustproof box, and together achieve effective protection for the internal components.

[0010] As a preferred embodiment, the filter component includes a first mounting retaining ring, a second mounting retaining ring disposed relative to the first mounting retaining ring, and a filter liner disposed between the first and second mounting retaining rings. The two ends of the filter liner are respectively connected to the first and second mounting retaining rings via a snap-fit ​​structure.

[0011] By adopting the above technical solution, the filter liner is fixed in a specific position through the interlocking structure between the first and second mounting rings, ensuring that it will not loosen or fall off during the filtration process. When air passes through the filter liner, impurities are trapped, thus ensuring that the filtered air meets the required cleanliness standards. This design not only facilitates filter liner replacement and ensures continuous filtration performance, but also improves the overall equipment's maintenance efficiency and operational safety.

[0012] As a preferred embodiment, the filter liner includes an inner filter screen, an outer filter screen disposed around the outer periphery of the inner filter screen, and an inner filter core disposed between the inner filter screen and the outer filter screen. The inner filter screen is made of fiber material and has filter holes uniformly disposed on it, and the filter holes are circular.

[0013] By adopting the above technical solution, a filter inner mesh, a filter outer mesh, and a filter inner core are constructed from fiber filaments. The uniform circular filter holes on the filter inner mesh effectively intercept and filter fine particles in the air; the filter outer mesh protects the filter inner mesh and inner core, preventing them from directly contacting impurities in the external environment; the filter inner core, located between the filter inner and outer meshes, further enhances the filtration effect and intercepts even smaller particles.

[0014] As a preferred embodiment, the cross-section of the filter core is wavy, and the inner side of the filter core is tangent to the inner filter mesh, the outer side of the filter core is tangent to the outer filter mesh, and the filter core is made of non-woven fabric.

[0015] By adopting the above technical solution, the cross-section is designed in a wavy shape. This unique shape increases the contact area between the filter core and the outer and inner filters, thereby improving the overall filtration efficiency. The inner side of the filter core is tangent to the inner filters, which helps enhance the filtration effect at the boundary and prevents larger particles from passing directly through the filter gaps. The outer side of the filter core is tangent to the outer filters, ensuring that the outer layer has a filter body for preliminary filtration, reducing the impact of impurities on the core filtration area. This structural design not only enhances the robustness and durability of the filter but also improves filtration efficiency and filter lifespan.

[0016] As a preferred embodiment, the filter outer mesh is made of stainless steel wire, which is formed by interlacing stainless steel wires radially and weft-wise. The stainless steel wire helps to ensure that the shape of the filter lining is not affected by wind.

[0017] By adopting the above technical solution, the high toughness and wear resistance of stainless steel wire enable the filter screen to maintain good structural strength and stability during long-term use, thus ensuring a good filtration effect for an extended period. In terms of working principle, when airflow containing impurities passes through the filter screen, the radially and latitudinally staggered stainless steel wires effectively block and filter out impurities. The radial and latitudinal structure of the stainless steel wires evenly distributes the airflow, ensuring that the airflow does not experience accelerated wear due to localized blockages. Simultaneously, the strength of the stainless steel wires ensures that the filter screen will not deform under external wind pressure, preventing a decrease in filtration efficiency.

[0018] As a preferred embodiment, the dustproof heat dissipation vent is composed of a spirally arranged convex reinforcing rib and an exhaust vent disposed between the reinforcing ribs, wherein the exhaust vent is arranged in a labyrinthine manner.

[0019] By adopting the above technical solutions, the reinforcing ribs enhance the rigidity and heat dissipation efficiency of the structure, ensuring its stability under high temperature and high load conditions; the labyrinth-shaped exhaust vents effectively guide and diffuse the heat dissipation airflow through a complex airflow path, reducing dust entry while improving heat dissipation.

[0021] 1. The tight connection between the sealing cover and the dustproof box ensures good sealing performance and prevents external dust from entering;

[0022] 2. The air inlet is located on the upper surface and is equipped with a filter, effectively introducing outside air and filtering out some dust. The axial fan at the bottom generates a vertical airflow to promptly remove heat from inside the dustproof box.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0036] like Figures 1 to 4 As shown, a dustproof enclosure for a communication transmission device includes a dustproof enclosure 1, a sealing cover 2 disposed at the opening of the dustproof enclosure 1, a connecting assembly disposed between the sealing cover 2 and the dustproof enclosure 1, an air inlet 4 disposed on the upper surface of the dustproof enclosure 1, a filter component 5 disposed within the air inlet 4, an axial flow fan 3 disposed on the lower surface of the dustproof enclosure 1 and positioned relative to the air inlet 4, and dustproof heat dissipation vents 6 disposed on both sides of the dustproof enclosure 1. The tight connection between the sealing cover 2 and the dustproof enclosure 1 ensures good sealing performance, preventing external dust from entering. The air inlet 4, located on the upper surface and equipped with the filter component 5, effectively introduces outside air and filters out some dust. The axial flow fan 3 at the bottom generates a vertical airflow, promptly removing heat from inside the dustproof enclosure. The dustproof and heat dissipation vents on both sides provide additional heat dissipation paths while effectively blocking dust from entering, ensuring a clean internal environment for the dustproof box. In turn, the efficient circulating air duct removes the heat generated during internal operation, maintaining a clean working environment and appropriate temperature, thereby ensuring the stable operation of the communication equipment and extending its service life.

[0037] Please refer to details. Figure 1 , Figure 2 , Figure 3 and Figure 4The connecting components include mounting plates 10 respectively disposed on the outer periphery of the opening end of the dustproof box 1, mounting holes evenly disposed at the four corners of the sealing cover 2, and fixing pins that pass through the mounting holes and connect to the mounting plates 10. The mounting plates 10 are provided with pin holes that are adapted to the fixing pins. The fixing pins pass through the mounting holes of the sealing cover 2 and the pin holes of the mounting plates 10 in sequence, and are fastened to form a tight connection, ensuring that the sealing cover 2 can be firmly installed on the dustproof box 1, and together achieve effective protection for the internal components.

[0038] Please refer to details. Figure 3 and Figure 4 The filter component 5 includes a first mounting ring 511, a second mounting ring 512 disposed relative to the first mounting ring 511, and a filter liner disposed between the first mounting ring 511 and the second mounting ring 512. Both ends of the filter liner are connected to the first mounting ring 511 and the second mounting ring 512 respectively via a snap-fit ​​structure. Through the snap-fit ​​structure between the first mounting ring 511 and the second mounting ring 512, the filter liner is fixed in a specific position, ensuring it will not loosen or fall off during the filtration process. When air passes through the filter liner, impurities are trapped, thus ensuring the filtered air meets the required cleanliness standard. This design not only facilitates filter liner replacement and ensures continuous filtration effectiveness but also improves the overall equipment's maintenance efficiency and operational safety.

[0039] Please refer to details. Figure 3 and Figure 4 The filter liner includes an inner filter screen 521, an outer filter screen 523 disposed around the outer periphery of the inner filter screen 521, and a filter core 522 disposed between the inner filter screen 521 and the outer filter screen 523. The inner filter screen 521 is made of fiber material and has uniformly arranged filter holes, which are circular. The uniformly arranged circular filter holes on the inner filter screen 521 can effectively intercept and filter fine particles in the air. The outer filter screen 523 protects the inner filter screen 521 and the filter core, preventing them from directly contacting impurities in the external environment. The filter core 522, located between the inner filter screen 521 and the outer screen, can further enhance the filtration effect and intercept even smaller particles. The overall working principle is as follows: air first passes through the outer filter screen 523, then enters the inner filter screen 521, then passes through the circular filter holes on the inner filter screen 521, and finally passes through the filter core 522, thereby achieving effective filtration and ensuring that the filtered air meets the predetermined purity requirements, thus guaranteeing the cleanliness of the air entering the inner cavity of the dustproof box 1.

[0040] Please refer to details. Figure 4The filter core 522 has a wavy cross-section, with its inner side tangent to the inner filter mesh 521 and its outer side tangent to the outer filter mesh 523. Made of non-woven fabric, the wavy cross-section of the filter core 522 increases the contact area between itself, the outer filter mesh 523, and the inner filter mesh 521, thereby improving overall filtration efficiency. The tangency between the inner side of the filter core 522 and the inner filter mesh 521 enhances filtration at the boundary, preventing larger particles from passing directly through the filter mesh gaps. The tangency between the outer side of the filter core 522 and the outer filter mesh 523 ensures that the outer layer has a filter body for preliminary filtration, reducing the impact of impurities on the core filtration area. This structural design not only enhances the robustness and durability of the filter but also improves filtration efficiency and filter lifespan. In terms of working principle, when the air to be filtered passes through the filter device, it is first initially filtered by the outer filter screen 523 to remove larger particles. Then the fluid enters the inner filter core 522. Due to the close contact between the wavy cross-section of the inner filter core 522 and the inner and outer screens, the air is subjected to multiple bends and repeated filtration as it passes through, ensuring thorough filtration and ultimately achieving a highly efficient and reliable filtration effect.

[0041] Please refer to details. Figure 3 and Figure 4 The outer filter mesh 523 is made of stainless steel wire, which is formed by interlacing radial and weft directions. The stainless steel wire ensures that the shape of the filter liner is not affected by wind. The high toughness and wear resistance of the stainless steel wire give the filter mesh good structural strength and stability during long-term use, thus maintaining good filtration performance for an extended period. In terms of working principle, when airflow containing impurities passes through the outer filter mesh 523, the radially and weftly interlaced stainless steel wire effectively blocks and filters out impurities. The radial and weft structure of the stainless steel wire evenly distributes the airflow, ensuring that the airflow does not wear down due to localized blockages. At the same time, the strength of the stainless steel wire ensures that the filter mesh will not deform under external wind pressure, thus preventing a decrease in filtration efficiency.

[0042] Please refer to details. Figure 3 and Figure 4 Figure 3 Figure 4The dustproof heat dissipation vent 6 consists of spirally arranged, outwardly convex reinforcing ribs 61 and exhaust vents 611 disposed between the reinforcing ribs 61. The exhaust vents 611 are arranged in a labyrinthine pattern. The reinforcing ribs 61 enhance the rigidity and heat dissipation efficiency of the structure, ensuring its stability under high temperature and high load conditions. The labyrinthine exhaust vents 611 effectively guide and diffuse the heat dissipation airflow through a complex airflow path, reducing dust entry while improving heat dissipation. In terms of working principle, air enters and flows through the labyrinthine exhaust vents 611 under the guidance of the spiral reinforcing ribs 61, increasing the airflow resistance and path length, thereby improving heat exchange efficiency. The complex path further reduces the chance of dust particle deposition, ultimately achieving effective heat dissipation and good dust prevention.

[0043] In this embodiment, during use, the air inlet 4 is located on the upper surface and is equipped with a filter component 5, effectively introducing outside air and filtering out some dust. The axial flow fan 3 at the bottom generates vertical airflow, promptly removing internal heat. The dustproof heat dissipation vents 6 on both sides provide additional heat dissipation paths while effectively preventing dust from entering, ensuring the cleanliness of the internal environment of the dustproof box 1. Furthermore, the efficient circulating air duct removes the heat generated during internal operation, maintaining a clean working environment and appropriate temperature, thereby ensuring the stable operation of the communication equipment and extending its service life.

[0044] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
