[0002] Communication optical cable is a telecommunication facility that uses optical fiber as a transmission medium. It transmits data through total internal reflection of optical signals. With its low attenuation, high speed and large capacity, it supports the data transmission needs of long-distance and urban communication networks. With the development of society, optical cables also need to be laid in the sea. Due to the complex environment, it is easy to cause damage to the optical cable, so a protective sleeve needs to be installed on the outside of the optical cable.

[0003] Most existing casings are ductile iron cable-connected casings. Since most of the application environments are oceans and beaches, although the surface of the casing is coated with a corrosion-resistant coating, the coating will corrode and rust after a period of use. If it is used for a long time, it will be seriously rusted. At the same time, due to the heavy weight of the casing, it is more troublesome to install. In view of the above problems, the technicians in this field have proposed a communication optical cable protection casing to solve the above problems. Utility Model Content

[0023] Specifically, a plurality of sub-hinged locking buckles 3 on one side of the shell 1 are inserted into the corresponding jacks on the main hinged locking buckle 4 on one side of the shell 2, so that a twisted locking connection can be achieved. At the same time, the opening and closing angle between the shell 1 and the shell 2 can reach 130°, which is convenient for installing the protective sleeve on the outside of the optical cable and improves the flexibility of use. The shell 1 is rotated to fit with the shell 2, and the buckle 6 is inserted into the interior of the slide groove 5 and moved laterally so that the protrusion on the inner side of the buckle 6 passes through the protrusion provided on the outside of the fixing block 8, thereby realizing the locking operation and realizing the closure of the shell 1 and the shell 2. The second screw hole 9 opened in the fixing block 8 cooperates with the first screw hole 7 opened on one side of the shell 2, and the shell 1 and the shell 2 can be connected and fixed with screws, thereby making the connection more firm.

[0024] Reference Figure 2 and Figure 3 The left ends of shell 1 and shell 2 are both provided with a second connecting head 11, and the right ends of shell 1 and shell 2 are both provided with shell 22.
