[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 cables. Therefore, a protective sleeve needs to be installed on the outside of the optical cables.

[0003] At present, the protective sleeves of communication optical cables usually adopt a more conventional structure and installation method. Generally, the various parts of the protective sleeve are fixed together by bolts and other connectors, which makes the operation more cumbersome during the installation process, requires the use of specific tools, and takes a long time. In addition, the connection between the protective sleeves is not flexible enough. When the optical cable is bent or twisted due to external influences, it cannot effectively relieve stress, which can easily cause damage to the optical cable and affect the communication quality and stability. Therefore, a communication optical cable protective sleeve with a quick-install structure is proposed to solve the above problems. Utility Model Content

The buckle 6 is used to fix the adjacent block 1 4 and block 2 5, firmly connecting the two blocks together, so that even under the action of external force, the half shells can maintain a stable connection. At the same time, the sub-twisted lock buckle 7 can be inserted into the jack of the female twisted lock buckle 8, so that the two half shells can be brought closer to each other by rotating the half shell 1. Through the cooperation of the block, the buckle 6 and the twisted lock buckle, the protective sleeve can be quickly installed and can protect the optical cable from damage caused by external factors.

[0036] Reference Figure 1 , Figure 5 and Figure 6, plug-in structures 3 are provided at both ends of half shell 1 and half shell 2, and the plug-in structure 3 is used for connecting two adjacent half shells 1 and half shells 2, and the plug-in structure 3 includes connector 1 301, connector 2 302, connector 3 303 and connector 4 304, connector 1 301 is arranged at one end of half shell 1, connector 2 302 is arranged at one end of half shell 2, connector 3 303 is arranged at the other end of half shell 1, and connector 4 304 is arranged at the other end of half shell 2, connector 1 301, connector 2 302, connector 3 303 and connector 4 304 are all arranged in a semicircular shape, and when half shell 1 and half shell 2 are spliced, the combination of connector 1 301 and connector 2 302 can be plugged between adjacent connector 3 303 and connector 4 304.

[0037] Specifically, the pipe head (a combination of connector one 301 and connector two 302) on the installed protective sleeve is first placed between connector three 303 and connector four 304 on the uninstalled protective sleeve, and then the uninstalled protective sleeve is installed, so that the pipe tail (connector three 303 and connector four 304) can be flexibly cooperated with the pipe head on the installed protective sleeve, and there is a 15° movable space after connection, thereby preventing the line from being twisted and damaged.
