At this time, ensure that the third mounting and embedding protrusions 9 on both sides of the assembly end plate 5 are embedded in the third mounting and embedding grooves 10 on the inner side of the two clamping fixed connection support right angle columns 6. Finally, take out the assembly top plate 3 and fix it with bolts at the top of the four clamping fixed connection support right angle columns 6. At this time, ensure that the irregular mounting protrusions 15 on the top surface of the clamping fixed connection support right angle columns 6 are embedded in the irregular mounting grooves 16 on the assembly top plate 3.
[0035] At this time, it is also necessary to ensure that the first sawtooth-shaped limiting protrusions 12 on the assembly base plate 2 and the assembly top plate 3 are fitted into the first sawtooth-shaped limiting grooves 11 on the upper and lower end faces of the assembly side plate 4, and at the same time, it is necessary to ensure that the second sawtooth-shaped limiting protrusions 14 on the assembly base plate 2 and the assembly top plate 3 are fitted into the second sawtooth-shaped limiting grooves 13 on the upper and lower end faces of the assembly end plate 5.
[0036] At this point, the assembly of the detachable and assembled ring network cabinet 1 is complete. Then, the sealing door 18 can be opened, and the working module can be installed in the detachable and assembled ring network cabinet 1. After the working module is installed, the sealing door 18 can be closed, and then you can wait for the operation to begin.
