Abstract: A case with screw thread in a sealed manner for communication equipment includes an upper cover and a bottom cover. The inner surface of the upper cover has an internal screw thread. The outer surface of the bottom cover has an external screw thread. When the external screw thread is fixed with the internal screw thread, the inner surface of the upper cover is in contact with the outer surface of the bottom cover in a sealed state, and the upper cover and the bottom cover form a receiving space. The case provides the following advantages: quickly and repeated assembly and disassembly; no need for any space for bolts so as to minimizes the size; without bolt, no need for washers or sealant; good sealing properties and good waterproof effect so as to prevent water from entering the case.
