[0024] See also Figure 1 、 Figure 2 as well as Figure 3 , an embodiment of the present invention provides a communication chassis that is easy to maintain, and the communication chassis that is easy to maintain includes:

[0025] The box body 1 and the wire entry pipe 2, the box body 1 is provided with a strip opening at the bottom, the wire entry pipe 2 is fixed at the bottom of the box body 1, and the cable can be passed through the wire entry pipe 2 into the box body 1; the flipping mechanism 3 is installed in the box body 1, and the flipping mechanism 3 is installed with a frame 4, and the flipping mechanism 3 is used to drive the frame 4 to rotate for easy maintenance; the disassembly and assembly mechanism 5 is installed in the frame 4 and is provided in plurality, and the plurality of disassembly and assembly mechanisms 5 are used to install or disassemble the communication equipment for easy maintenance of the communication equipment; the lead-in mechanism 6 is installed on the inner wall of the box body 1 and the frame 4, and is used to pass the cable passing through the wire entry pipe 2 into the frame 4 by the lead-in mechanism 6 and connect it to the communication equipment; the fixing mechanism 7 is fixedly installed on the back of the box body 1 for installing the box body 1.

[0026] When using the communication chassis that is easy to maintain, first place the communication equipment on the disassembly and assembly mechanism 5 for installation and fixation, then pass the cable through the wire entry pipe 2 and the lead-in mechanism 6 and connect it to the communication equipment on the disassembly and assembly mechanism 5. When cleaning and maintaining the communication equipment, the cable can be removed from the communication equipment, and the flip mechanism 3 can be used to control the rotation of the frame 4, so as to facilitate cleaning of the front and back of the communication equipment. If the communication equipment fails, the communication equipment can be removed from the disassembly and assembly mechanism 5 for maintenance, and the fixing mechanism 7 can fix the box body 1 to the specified position for installation.

[0027] like Figure 2 As shown, as a preferred embodiment of the present invention, the flipping mechanism 3 includes: an axle rod 31, which is provided with two ends that are rotatably connected to the inner wall of the box body 1 and are far away from each other, and the two axle rods 31 are fixedly connected to the frame 4 at their ends that are close to each other, and a limited turntable 32 is fixedly provided on the lower side of the axle rod 31, and a limited turntable opening is opened on the limited turntable 32; a rotating column 33, one end of which is fixedly connected to the lower side axle rod 31, and the other end of the rotating column 33 is fixedly connected to a handle 34, and the handle 34 is used to control the rotation of the frame 4 through the rotating column 33; a rotation limiting component 35, which is installed on the lower side of the box body 1 and is sleeved on the rotating column 33, and the rotation limiting component 35 is used to be inserted into the rotation limiting opening opened by the rotation limiting disk 32 to limit the rotation of the frame 4.

[0028] When the control frame 4 is rotated to facilitate cleaning of the back of the communication device, the control end of the rotation limit component 35 is pushed. After the rotation limit component 35 is disengaged from the rotation limit opening opened by the rotation limit disk 32, the handle 34 is turned. The handle 34 drives the rotating column 33 and the shaft 31 to rotate.

At this time, the top spring 56 can make the top plate 57 push the insertion plate 53 and the wheel groove 54 to move a short distance along the guide wheel 52 to the outside of the guide groove 51. At this time, the control handle 510 can be pulled, and the control handle 510 can drive the carrier plate 58 to move outward as a whole, so that the clamping component 59 and the communication equipment can be taken out of the box body 1 for cleaning. After the cleaning is completed, the insertion plate 53 on the carrier plate 58 is aligned with the guide groove 51 and inserted. When the card slot and the card-in component 55 are flush, the card-in component 55 can be snapped into the card slot, so that the insertion plate 53 can be fixed, and the communication equipment can be installed and removed on the clamping component 59, which is convenient for further maintenance or repair of the communication equipment.
