[0030] A plurality of plug-in ports 12 are provided on one side of the vertical plate 2, and a plurality of limit shells 13 are fixedly provided on one side of the vertical plate 2. A moving shell 14 and an L-shaped moving plate 15 are slidably connected in each of the limit shells 13 through a track structure. The moving plate 15 is movably connected to the moving shell 14, and placement grooves 16 are respectively provided on the moving plate 15 and the moving shell 14.

[0031] In this embodiment, when it is necessary to inspect the components inside the signal transceiver installation chassis, the handle 11 is turned, the handle 11 drives the two driving bevel gears 9 to rotate, the driving bevel gears 9 drive the driven bevel gears 10 to rotate, the driven bevel gears 10 drive the lead screw 4 to rotate, and since the lead screw 4 is threadedly connected with the moving bar 5, the two moving bars 5 move away from the vertical plate 2 at the same time, and the moving bar 5 drives the upper shell 6 to move, so that the upper shell 6 is separated from the bottom plate 1 and the vertical plate 2, thereby opening the entire installation chassis, and the upper shell 6 can also be disassembled according to maintenance needs. When the inspection is completed, the entire installation chassis can be closed using the opposite operation.

[0032] More specifically, the handle 11 can be turned to move the upper shell 6 to open it when inspecting the components inside the signal transceiver installation chassis. When it is necessary to plug the optical fiber into the plug port 12, the movable plate 15 and the movable shell 14 are moved in a direction away from each other to expose the plug port 12, and the optical fiber connector is inserted into the plug port 12. The movable plate 15 and the movable shell 14 are moved in adjacent directions to place the optical fiber into the placement groove 16 and clamp it. When the plug port 12 is not needed, the movable plate 15 and the movable shell 14 are moved in adjacent directions to move one end of the movable plate 15 into the movable shell 14, and the plug port 12 is shielded from dust with the cooperation of the movable plate 15 and the movable shell 14.

[0033] See also Figure 1-5 , as an implementation method for simultaneously moving the moving plate 15 and the moving shell 14: two first springs 17 are fixedly connected between one side of the moving plate 15 and the moving shell 14 and the limiting shell 13 respectively, an L-shaped first rack 18 is fixedly arranged at the lower end of the moving shell 14, a second rack 19 is fixedly arranged at the lower end of the moving plate 15, the first rack 18 and the second rack 19 are both meshed and linked with a gear column 20, a handle 21 is fixedly arranged on one side of the limiting shell 13, one end of the handle 21 extends into the limiting shell 13 and is fixedly connected to the gear column 20.

[0034] Specifically, the handle 21 is turned, and the handle 21 drives the gear column 20 to rotate. Since the gear column 20 is meshed with the first rack 18 and the second rack 19, the first rack 18 and the second rack 19 move in the separation direction at the same time. The first rack 18 and the second rack 19 respectively drive the movable shell 14 and the movable plate 15 to move along the sliding connection with the limit shell 13, and the first spring 17 is compressed. When the optical fiber is plugged in, the handle 21 is released, and under the push of the second spring 25, the movable plate 15 and the movable shell 14 move in adjacent directions.

[0036] Specifically, when the throttle 11 needs to be rotated, the pull rod 23 is pulled. The throttle 11 is provided with a socket that matches the pull rod 23. One end of the pull rod 23 moves out of the socket of the throttle 11. At the same time, the pull rod 23 drives the limit ring 24 to move, and the second spring 25 is compressed. At this time, the throttle 11 can be rotated. When the throttle 11 is used, the socket on the throttle 11 is aligned with the pull rod 23. The pull rod 23 is released. Under the push of the second spring 25, the limit ring 24 drives the pull rod 23 to be inserted into the socket, thereby fixing the throttle 11.

[0037] In summary, when the overall equipment is in use:

[0038] When the optical fiber needs to be plugged in, the handle 21 is turned, and the handle 21 drives the gear column 20 to rotate. Since the gear column 20 is meshed and connected with the first rack 18 and the second rack 19, the first rack 18 and the second rack 19 move in the separation direction at the same time, and the first rack 18 and the second rack 19 respectively drive the movable shell 14 and the movable plate 15 to move along the sliding connection with the limit shell 13, and the first spring 17 is compressed. At this time, the plug-in port 12 is exposed, and the optical fiber connector is inserted into the plug-in port 12. The handle 21 is released, and under the push of the second spring 25, the movable plate 15 and the movable shell 14 move in adjacent directions, so that the optical fiber is placed in the placement groove 16 and clamped and fixed. When the plug-in port 12 is not needed, the movable plate 15 and the movable shell 14 move in adjacent directions, so that one end of the movable plate 15 moves into the movable shell 14, and the plug-in port 12 is shielded and dust-proofed with the cooperation of the movable plate 15 and the movable shell 14.

[0039] When the throttle 11 needs to be rotated, the pull rod 23 is pulled. The throttle 11 is provided with a socket that matches the pull rod 23. One end of the pull rod 23 moves out of the socket of the throttle 11. At the same time, the pull rod 23 drives the limit ring 24 to move, and the second spring 25 is compressed. At this time, the throttle 11 can be rotated. When the throttle 11 is used, the socket on the throttle 11 is aligned with the pull rod 23. The pull rod 23 is released. Under the push of the second spring 25, the limit ring 24 drives the pull rod 23 to be inserted into the socket, thereby fixing the throttle 11.

[0040] When it is necessary to inspect the internal components of the signal transceiver installation chassis, turn the handle 11, the handle 11 drives the two driving bevel gears 9 to rotate, the driving bevel gear 9 drives the driven bevel gear 10 to rotate, the driven bevel gear 10 drives the lead screw 4 to rotate, and since the lead screw 4 is threadedly connected to the moving bar 5, the two moving bars 5 move away from the vertical plate 2 at the same time, and the moving bar 5 drives the upper shell 6 to move, so that the upper shell 6 is separated from the bottom plate 1 and the vertical plate 2, thereby opening the entire installation chassis, and the upper shell 6 can also be removed according to maintenance needs. When the inspection is completed, the entire installation chassis can be closed using the opposite operation. A plurality of heat dissipation ports are provided on the outside of the upper shell 6, and a filter is provided on each heat dissipation port.

In the above, all fixed connections are preferably welded.
