Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and more specifically, to a communication switch with a detachable dustproof mesh. Background Technology

[0002] Switches typically operate in various environments, and dust in the air can easily enter their interiors with airflow. Excessive dust accumulation can cause various forms of damage to the switch's electronic components. First, dust may accumulate on circuit boards, affecting signal transmission between electronic components, leading to data exchange errors or communication interruptions. Second, dust buildup on heat dissipation components hinders heat dissipation, causing the internal temperature of the switch to rise, thus affecting the performance and lifespan of the electronic components. Furthermore, dust can also absorb moisture from the air, causing serious problems such as short circuits on the circuit boards.

[0003] To prevent dust from entering switches, current technology typically uses dust filters at the switch's air inlet. However, traditional dust filters have several shortcomings. Firstly, most dust filters are complex to install and difficult to disassemble. When a large amount of dust accumulates and needs cleaning or replacement, operators often need to spend considerable time and effort, sometimes even requiring specialized tools. This not only increases maintenance costs but also affects the switch's uptime. Secondly, traditional dust filters have poor sealing, allowing dust to easily enter the switch's interior through the gaps, reducing their dust-proof effectiveness. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes a communication switch with a detachable dustproof net.

[0005] A communication switch with a detachable dustproof screen includes:

[0006] The enclosure is internally divided into several independent switch mounting layers by multiple partitions. Each mounting layer has a removable dustproof screen on the air inlet side, and the dustproof screen has an array of ventilation holes.

[0007] The fixed structure is located on the air inlet side of the enclosure and includes a mounting plate extending along the depth of the enclosure. The mounting plate has four sets of fixing screw holes corresponding to each mounting layer. The dustproof net has mounting screw holes at its four corners that correspond one-to-one with the fixing screw holes. The dustproof net is fixed by passing fixing bolts through the fixing screw holes and mounting screw holes.

[0008] A sealing and fixing plate covers the outer side of the gap between two adjacent dustproof nets. Its inner side is provided with positioning screw holes that match the installation screw holes of the upper and lower dustproof nets. The sealing and fixing plate is fixed by passing the fixing bolts through the positioning screw holes and the installation screw holes.

[0009] More preferably, the dustproof net has symmetrical handles at both ends for easy gripping, and the handles are provided with anti-slip texture.

[0010] More preferably, the inner side of the sealing fixing plate is provided with an elastic sealing strip, the cross-sectional shape of which is adapted to the gap between adjacent dustproof nets, and is used to fill the gap to achieve sealing.

[0011] More preferably, the width of the front end of the sealing strip near the air inlet is smaller than the width of the rear end away from the air inlet, forming a wedge-shaped structure that is narrower at the front and wider at the back.

[0012] More preferably, the sealing and fixing plate has end plates at both ends that are perpendicular to the sealing and fixing plate, and the end plates and the sealing and fixing plate together form an I-shaped cross section; the end plates have positioning screw holes corresponding to the mounting screw holes, and the end plates are connected to the mounting plate by fixing bolts.

[0013] Beneficial effects:

[0014] 1. Easy to maintain: The dustproof net is connected to the mounting plate by the fixing bolts at the four corners. The disassembly and installation process is simple and quick, without the need for professional tools. Operators can easily complete the process. The handle design further facilitates the gripping of the dustproof net, making the cleaning or replacement of the dustproof net more efficient, greatly reducing maintenance costs and reducing the downtime of the switch due to maintenance.

[0015] 2. Excellent dustproof performance: The combination of the sealing plate and the elastic sealing strip effectively fills the gap between adjacent dustproof nets, and the wedge-shaped sealing strip has a better sealing effect under air pressure, which can block dust from entering the inside of the switch in all directions, ensure the cleanliness of the electronic components inside the switch, extend the service life of the switch, and improve communication quality.

[0016] 3. Stable structure: The four-corner fixing method of the fixed structure and the I-shaped cross-section design of the sealing fixing plate ensure that the dustproof net and the sealing fixing plate are firmly installed.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] like Figures 1-2 The communication switch shown has a detachable dustproof net 4 and consists of a housing 1, a fixing structure and a sealing fixing plate 8.

[0022] The interior of the enclosure 1 is divided into several independent switch installation layers by multiple partitions 2. This layered design is conducive to the classified installation of switches with different functions or specifications, which facilitates management and maintenance. Each installation layer has a removable dustproof net 4 on the air inlet side. The dustproof net 4 has an array of ventilation holes. The array of ventilation holes can ensure that air enters the installation layer evenly, providing good ventilation and heat dissipation conditions for the switches. At the same time, the dustproof net 4 can effectively block dust and prevent it from entering the installation layer and damaging the switches.

[0023] The fixed structure is set on the air inlet side of the box 1, including the mounting plate 3 extending along the depth direction of the box 1. The mounting plate 3 has four sets of fixing screw holes 5 corresponding to each mounting layer. Its function is to provide connection points for fixing the dustproof net 4. The four corners of the dustproof net 4 have mounting screw holes 6 that correspond one-to-one with the fixing screw holes 5. The dustproof net 4 is fixed by the fixing bolts 9 passing through the fixing screw holes 5 and the mounting screw holes 6. This four-corner fixing method makes the dustproof net 4 firmly installed and not easy to shake or fall off due to air flow during ventilation.

[0024] Sealing gap: The sealing fixing plate 8 covers the outside of the gap between two adjacent dustproof meshes 4. Its inner side is provided with positioning screw holes that match the mounting screw holes 6 of the upper and lower dustproof meshes 4. The sealing fixing plate 8 is fixed by the fixing bolts 9 passing through the positioning screw holes and mounting screw holes 6. The setting of the sealing fixing plate 8 effectively fills the gap between two adjacent dustproof meshes 4, preventing dust from entering the inside of the switch from the gap and enhancing the dustproof effect.

[0025] Elastic sealing strip 801: An elastic sealing strip 801 is provided on the inner side of the sealing fixing plate 8. The cross-sectional shape of the sealing strip 801 is adapted to the gap between the adjacent dustproof nets 4, which further improves the sealing performance. The width of the front end of the sealing strip 801 near the air inlet side is smaller than the width of the rear end away from the air inlet side, forming a wedge-shaped structure that is narrow at the front and wide at the back. The gap between the two adjacent layers of dustproof nets 4 is located on the outside of the partition plate 2. The sealing strip 801 is pressed between the outside of the partition plate 2 and the two dustproof nets 4. This wedge-shaped structure allows the sealing strip 801 to better fit the gap when subjected to air inlet pressure, enhancing the sealing effect and effectively blocking dust.

[0026] End plate 802 design: The sealing and fixing plate 8 has end plates 802 perpendicular to the sealing and fixing plate 8 at both ends. The end plates 802 and the sealing and fixing plate 8 together form an I-shaped cross section. The end plates 802 are provided with positioning screw holes corresponding to the mounting screw holes 6. The end plates 802 are connected to the mounting plate 3 by fixing bolts 9. The I-shaped cross section design not only enhances the structural strength of the sealing and fixing plate 8, but also facilitates the connection with the mounting plate 3, ensuring that the sealing and fixing plate 8 is firmly installed and not easy to loosen.

[0027] The dustproof net 4 has symmetrical handles 7 at both ends for easy gripping, and the handles 7 are textured with anti-slip texture. The design of the handles 7 makes it easy for operators to disassemble and install the dustproof net 4, while the anti-slip texture increases the friction when the operator grips the handles 7, preventing the dustproof net 4 from falling off due to slippage during operation, thus improving the safety and convenience of operation.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
