[0003] In related technologies, the main body of the network device needs to be mounted on a support plate, which is connected to an external air source. The airflow channel within the support plate is connected to the air outlet of the network device main body. During use, gaps may appear at the contact surface between the network device main body and the support plate due to factors such as machining accuracy, assembly accuracy, or aging. Airflow may leak from these gaps, leading to insufficient stability of the airflow pressure. Utility Model Content

[0007] Furthermore, the first inclined surface has a first groove, the first seal is embedded in the first groove, and the second inclined surface presses against the first seal.

[0008] Furthermore, the slope of the second inclined plane is greater than the slope of the first inclined plane so that a gap 5 with gradually decreasing width is formed between the first inclined plane and the second inclined plane, extending from the side where the main body is located to the side where the support plate is located.

[0009] Furthermore, the support plate has a second sealing groove, the main body is provided with a sealing ring embedded in the second sealing groove, a second sealing element is embedded in the second sealing groove, and the sealing ring compresses the second sealing element.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1 to 5 This embodiment discloses a network device, including a support plate 100 and a main body 200. A fixing plate 230 is connected to the main body 200, and the fixing plate 230 is fixed to the support plate 100 by fasteners 231, thereby mounting the main body 200 onto the support plate 100. A cable passage 201 is provided within the main body 200. A mounting portion 220 extending towards the support plate 100 is provided at the bottom of the main body 200, and an air outlet 210 is provided in the mounting portion 220. The cable passage 201 communicates with the air outlet 210. An airflow channel 110 is provided in the support plate 100, and the positions of the airflow channel 110 and the air outlet 210 correspond to each other so that the airflow channel 110 communicates with the air outlet 210. The airflow channel 110 and the cable passage 201 are perpendicular to each other.

[0022] The airflow channel 110 has a limiting opening 120 at one end facing the main body 200 for the mounting part 220 to be inserted. The limiting opening 120 includes a first inclined surface 121 inclined towards the center of the limiting opening 120, and the mounting part 220 includes a second inclined surface 221 inclined towards the center of the mounting part 220. The slope of the second inclined surface 221 is greater than the slope of the first inclined surface 121 so that a gap 500 with a gradually decreasing width is formed between the first inclined surface 121 and the second inclined surface 221 extending from the side where the main body 200 is located towards the side where the support plate 100 is located. The first inclined surface 121 has a first groove 122, and a first sealing member 123 is embedded in the first groove 122. The first sealing member 123 is made of rubber, and the second inclined surface 221 compresses the first sealing member 123. As the mounting part 220 is embedded in the limiting port 120, the width of the time interval 500 continuously decreases, thereby increasing the pressure on the first seal 123. This strengthens the sealing performance between the mounting part 220 and the limiting port 120, thus maintaining stable airflow pressure.

[0023] The support plate 100 has an annular second sealing groove 130 surrounding the limiting opening 120. The main body 200 is provided with a sealing ring 202 embedded in the second sealing groove 130, and a second sealing element 131, made of rubber, is embedded in the second sealing groove 130. The sealing ring 202 compresses the second sealing element 131. The second sealing element 131 and the first sealing element 123 form a double sealing structure, thereby further enhancing the sealing performance between the support plate 100 and the main body 200 and preventing air leakage that could lead to insufficient pressure entering the wire passage 201.

[0024] The air outlet 210 has a transition surface 211 that slopes towards the side wall of the airflow channel 110 at its opening towards the airflow channel 110. Simultaneously, a protrusion 124 extending towards the center of the airflow channel 110 is provided at the limiting port 120. The protrusion 124 abuts against the mounting portion 220, thus supporting the mounting portion 220. The upper end face of the protrusion 124 is on the same plane as the first inclined surface 121, and the lower end face of the protrusion 124 is on the same plane as the transition surface 211, thus guiding the airflow entering the air outlet 210 from the airflow channel 110.

[0025] The airflow channel 110 is connected to the air outlet 210, and the other end is connected to the airflow pipe 300. A third seal 310 is embedded between the end face of the airflow pipe 300 and the bottom surface of the support plate 100. The third seal 310 is made of rubber. The airflow channel 110 and the airflow pipe 300 are connected by threads. When the airflow pipe 300 is connected to the airflow channel 110, the end face of the airflow pipe 300 presses against the third seal 310, thereby increasing the sealing performance between the airflow pipe 300 and the support plate 100.

[0026] The support plate 100 has a plug-in groove 140, an elastic cylinder 150 is embedded in the plug-in groove 140, an installation groove 151 is embedded in the elastic cylinder 150, a guide 400 is embedded in the installation groove 151, and a guide hole 410 is provided in the guide 400, which can guide the yarn entering and exiting the yarn passage 201.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
