A clamping plate 309 is arranged on the top of the sliding ring 308, and the sliding ring 308 is clamped in the clamping plate 309. When the interface protection upper shell 302 is rotated upward to open, the sliding ring 308 is separated from the clamping plate 309, and when the interface protection upper shell 302 is rotated downward to close, the sliding ring 308 is clamped in the clamping plate 309.

[0032] like Figure 4 As shown, a clamping structure 2 is also included. A clamping structure 2 is provided between the mounting shell 101 and the sliding shell 102. The clamping structure 2 includes a clamping block 202 and a torsion spring 203. The right outer portions of the front and rear walls of the mounting shell 101 are rotatably connected with the clamping block 202.

A torsion spring 203 is provided at the rotational connection between the clamping block 202 and the mounting shell 101. The front and rear walls of the sliding shell 102 are both provided with clamping grooves 201, and the clamping block 202 can be clamped into the clamping grooves 201.

[0033] like Figure 8 and Fig. 9As shown, it also includes a wire outlet sealing structure 4, the wire outlet sealing structure 4 is arranged on the sliding housing 102 at the threading port 103, the wire outlet sealing structure 4 includes a collar 401, an L-shaped hollow rod 402, a piston rod 403, a push plate 404, a spring III 405 and an airbag 406, the sliding housing 102 at the threading port 103 is provided with a collar 401, and the sliding housing 102 outside the collar 401 is evenly spaced and provided with L-shaped hollow rods 402, two L-shaped hollow rods 402 are grouped, and are respectively arranged on the collar 40 1, the left part of the L-shaped hollow rod 402 is slidably connected with a piston rod 403, a push plate 404 is connected to the left end of each group of piston rods 403, and the push plate 404 can contact the pressure ring 305 when moving to the left, a spring III 405 is connected between the piston rod 403 and the L-shaped hollow rod 402, and an air bag 406 is connected between the right ends of the L-shaped hollow rod 402. The air bag 406 is annular, and the axis of the air bag 406, the axis of the collar 401, the center of the push plate 404 and the center of the pressure ring 305 are on the same horizontal line.

[0034] When the Ethernet cable interface needs to be plugged into the switch, the left part of the card block 202 needs to be pressed inwards first. At this time, the torsion spring 203 is deformed, and the right part of the card block 202 is no longer stuck in the card slot 201. Then, the sliding housing 102 is pulled out to the right side. Figure 1 Then insert the Ethernet cable interface from the ring 401 to the left side of the sliding housing 102, and then rotate the interface protection upper shell 302 upward to Figure 7 The Ethernet cable interface is connected to the switch body 1 through the pressure ring 305 and the interface protection bottom shell 301, and then the interface protection upper shell 302 is rotated to reset. Figure 6The state of the sliding housing 102 is then pushed to move to the left side and close with the installation housing 101. At this time, the pushing plate 404 moves to the left side and contacts the pressing ring 305, and the pressing ring 305 is pushed to move to the left side to squeeze the elastic sleeve 303. The spring I 306 and the spring II 3010 are compressed, so that the elastic sleeve 303 can fit tightly on the outer surface of the Ethernet cable, so that there is no gap between the Ethernet cable and the elastic sleeve 303, preventing water vapor from entering the interface. At the same time, the interface protection bottom shell 301 and the interface protection upper shell 302 are pressed against each other. Because of the existence of the sealing strip 3011, the gap between the protection bottom shell and the interface protection upper shell 302 is filled, preventing water vapor from entering from the gap between the protection bottom shell and the interface protection upper shell 302, further preventing the entry of water vapor; when the pushing plate 404 moves to the left side and contacts the pressing ring 305, under the action of the reaction force, the piston rod 403 enters the L-shaped hollow rod 402, and the elastic sleeve 303 is pressed against the outer surface of the Ethernet cable. The spring III 405 is compressed, and the gas in the L-shaped hollow rod 402 enters the airbag 406, causing the airbag 406 to expand. The inner surface of the airbag 406 is tightly attached to the outer surface of the external network cable, and the outer surface of the airbag 406 is attached to the ring 401, so that the external water vapor has no way to enter the installation shell 101 and the sliding shell 102, further preventing moisture from entering; when it is necessary to open the installation shell 101 and the sliding shell 102 to repair the switch body 1, first press the left part of the card block 202 inwardly to make the card block 202 disengage from the card slot 201, at this time, under the action of the spring I 306, the spring II 3010 and the spring III 405 reset, the sliding shell 102 is driven to move outward and reset, and at the same time the L-shaped hollow rod 402 is reset, the gas in the airbag 406 returns to the L-shaped hollow rod 402, the airbag 406 shrinks, and no longer fits the Ethernet cable and the ring 401, and then the interface protection upper shell 302 is rotated to Figure 7 Therefore, the sliding ring 308 is stuck in the card plate 309, and the card plate 309 will not hinder the interface protection upper shell 302 and its upper components from rotating upward, and then the switch body 1 can be repaired.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
