[0002] With the rapid development of Internet technology, in order to meet the requirements of Internet communication, the number of network servers is also increasing. Network cabinets are used to place a certain number of network servers, which is convenient for unified placement and centralized management. Existing network cabinets are often provided with cooling fans and cooling holes for heat dissipation. A dust-proof net is covered outside the cooling holes to prevent dust from entering the cabinet. Dust adheres to the surface of the dust-proof net and needs to be removed and replaced regularly to ensure the heat dissipation effect.

[0003] Existing dust-proof nets are usually fixed with a number of screws. Therefore, a large number of screws need to be disassembled and assembled every time the dust-proof net is disassembled and assembled. The process requires the use of tools and is very inconvenient. Moreover, the screws are small in size and are easily lost during the disassembly and assembly process. For this reason, a dust-proof net structure for a network cabinet is proposed. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a dust-proof net structure for a network cabinet, so as to solve the problem that existing dust-proof nets are usually fixed with a number of screws. Therefore, a large number of screws need to be disassembled and assembled every time the dust-proof net is disassembled and assembled. The process requires the use of tools and is very inconvenient. Moreover, the screws are small in size and are easily lost during the disassembly and assembly process.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A dust-proof net structure for a network cabinet, including a cabinet body and a dust-proof outer frame. A ventilation opening is provided on the surface of the cabinet body, and a sealing groove is provided around the outside of the ventilation opening. A square frame is welded on the surface of the cabinet body.

[0006] The dust-proof outer frame is installed inside the square frame, and a dust-proof inner net is integrally provided inside the dust-proof outer frame. A rubber sealing strip is attached to the side of the dust-proof outer frame close to the cabinet body. A lower limit mechanism is fixed at the bottom of the dust-proof outer frame, and an upper limit mechanism is provided at the top of the dust-proof outer frame. Both the lower limit mechanism and the upper limit mechanism include a groove, a spring, a limit plate, a protruding plate, and a through groove. Grooves are provided at both the upper and lower ends of the dust-proof outer frame, and springs are installed inside the grooves. The top of the spring is fixedly connected to a limit plate, and a protruding plate is welded on the surface of the limit plate.

[0007] Preferably, the inner surface of the sealing groove is attached to the outer surface of the rubber sealing strip, and the outer wall of the dust-proof outer frame is attached to the inner wall of the square frame.

[0008] Preferably, the thickness of the square frame is equal to that of the dust-proof outer frame, and the dust-proof inner net covers the surface of the ventilation opening through the dust-proof outer frame.

[0009] Preferably, the limiting plate forms a telescopic structure with the dust-proof outer frame through a spring, and the external dimensions of the limiting plate match the internal dimensions of the lower limiting groove and the upper limiting groove.

[0010] Preferably, a through groove is formed on the surface of the dust-proof outer frame, and one end of the protruding plate away from the limiting plate passes through the through groove and penetrates out of the surface of the dust-proof outer frame.

[0011] Preferably, an anti-slip rubber pad is bonded to the outer side of the end of the protruding plate away from the limiting plate, and the protruding plate is perpendicular to the limiting plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Specific implementation manner

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0023] The embodiments of the present invention will be described below according to its overall structure.

[0024] Please refer to Figures 1-6 , a dust-proof net structure of a network cabinet, including a cabinet body 1 and a dust-proof outer frame 7. A ventilation opening 2 is provided on the surface of the cabinet body 1, and a sealing groove 3 is provided around the outside of the ventilation opening 2. A square frame 4 is welded on the surface of the cabinet body 1. A lower limit groove 5 is provided at the inner bottom of the square frame 4, and an upper limit groove 6 is provided at the inner top of the square frame 4;

[0025] The dust-proof outer frame 7 is installed inside the square frame 4, and a dust-proof inner net 8 is integrally arranged inside the dust-proof outer frame 7. A rubber sealing strip 9 is attached to the side of the dust-proof outer frame 7 close to the cabinet body 1. The inner surface of the sealing groove 3 is attached to the outer surface of the rubber sealing strip 9, and the outer wall of the dust-proof outer frame 7 is attached to the inner wall of the square frame 4. The dust-proof net is composed of the dust-proof outer frame 7 and the dust-proof inner net 8. The dust-proof net card is installed inside the dust-proof outer frame 7, and the rubber sealing strip 9 is snapped into the sealing groove 3. Through the settings of the rubber sealing strip 9 and the sealing groove 3, the connection gap between the dust-proof net and the cabinet body 1 is filled, preventing dust from entering the interior of the cabinet body 1 through the gap. The thickness of the square frame 4 is equal to the thickness of the dust-proof outer frame 7, and the dust-proof inner net 8 covers the surface of the ventilation opening 2 through the dust-proof outer frame 7. This setting ensures that after the dust-proof net is installed, the dust-proof net and the square frame 4 are on the same horizontal plane, preventing the dust-proof net from protruding outward and improving the aesthetics of the device. A lower limit mechanism 10 is fixed to the bottom of the dust-proof outer frame 7, and an upper limit mechanism 11 is arranged at the top of the dust-proof outer frame 7. Both the lower limit mechanism 10 and the upper limit mechanism 11 include a groove 12, a spring 13, a limiting plate 14, a protruding plate 15, and a through groove 16. Grooves 12 are arranged at both the upper and lower ends of the dust-proof outer frame 7, and springs 13 are installed inside the grooves 12. The top of the spring 13 is fixedly connected to the limiting plate 14, and a protruding plate 15 is welded to the surface of the limiting plate 14. The limiting plate 14 forms a telescopic structure with the dust-proof outer frame 7 through the spring 13, and the external dimensions of the limiting plate 14 match the internal dimensions of the lower limit groove 5 and the upper limit groove 6. The state of the limiting plate 14 is adjusted by the spring 13. When installing the dust-proof net, by compressing the spring 13, the limiting plate 14 is retracted into the groove 12. Then, the dust-proof net is pushed into the dust-proof outer frame 7, causing the spring 13 to reset and the limiting plate 14 to extend out of the groove 12 and snap into the lower limit groove 5 and the upper limit groove 6 to fix the dust-proof net. Through grooves 16 are formed on the surface of the dust-proof outer frame 7, and one end of the protruding plate 15 away from the limiting plate 14 passes through the through groove 16 and extends out of the surface of the dust-proof outer frame 7. By pressing the protruding plate 15, the limiting plate 14 squeezes the spring 13 to achieve the telescoping of the limiting plate 14. An anti-slip rubber pad is adhered to the outer side of one end of the protruding plate 15 away from the limiting plate 14, and the protruding plate 15 is perpendicular to the limiting plate 14. This setting makes it difficult for the staff to slip when pressing the limiting plate 14, facilitating the disassembly and assembly of the dust-proof net.

[0026] Working principle: When in use, the staff needs to press the protruding plate 15. Since the protruding plate 15 is fixed to the limiting plate 14, when the limiting plate 14 is subjected to pressure, it squeezes the spring 13, causing the spring 13 to contract. The limiting plate 14 is contracted into the groove 12. Subsequently, the dust-proof net is pushed into the dust-proof outer frame 7 until the rubber sealing strip 9 on the dust-proof outer frame 7 is snapped into the sealing groove 3 on the cabinet body 1. Through the settings of the rubber sealing strip 9 and the sealing groove 3, the connection gap between the dust-proof outer frame 7 and the cabinet body 1 is filled, and dust cannot enter the interior of the cabinet body 1 through the gap. The dust-proof outer frame 7 is completely snapped into the square frame 4 until the right side surface of the dust-proof outer frame 7 is on the same horizontal plane as the right side surface of the square frame 4. Subsequently, the staff releases the protruding plate 15, causing the spring 13 to reset. The limiting plate 14 in the lower limiting mechanism 10 extends out of the groove 12 under the thrust of the spring 13, and the limiting plate 14 in the upper limiting mechanism 11 is inserted into the upper limiting groove 6, thus realizing the fixation of the dust-proof net.
