【 中文摘要 】本实用新型提供一种铁路通信干线光缆接头保护装置，该铁路通信干线光缆接头保护装置，包括上壳体，上壳体底部设置有下壳体，上壳体顶部设置有维修块，上壳体通过开设的维修孔与维修块外表面连接，上壳体内部设置有安装机构，安装机构包括固定杆，固定杆设置于上壳体开设的通孔内部，固定杆延伸出上壳体一端连接有拉盖。本实用新型提供的铁路通信干线光缆接头保护装置解决了现有光缆接头保护装置后续需要对光缆进行维修时，需要将多组螺丝依次取下，然后将上壳体与下壳体分离，进而对光缆进行维修，使得后续对于光缆的维修过程较为繁琐，工人需要完成对多组螺丝的拆卸与安装，一定程度上提高工人工作强度的问题。

【 英文摘要 】The present invention provides a railway communication trunk line optical cable joint protection device. The railway communication trunk optical cable joint protection device, Comprising an upper housing, A lower shell is arranged at the bottom of an upper shell, a maintenance block is arranged at the top of the upper shell, the upper shell is connected with the outer surface of the maintenance block through a maintenance hole formed in the upper shell, a mounting mechanism is arranged in the upper shell and comprises a fixing rod, the fixing rod is arranged in a through hole formed in the upper shell, and one end of the fixing rod extending out of the upper shell is connected with a pull cover. The protective device for the optical cable joint of the railway communication trunk line provided by the utility model solves the problem that the existing optical cable joint protective device needs to maintain the optical cable subsequently, A plurality of groups of screws need to be taken down in sequence, then the upper shell and the lower shell are separated, and then the optical cable is maintained, so that the follow-up maintenance process of the optical cable is complicated, workers need to complete disassembly and assembly of the plurality of groups of screws, and the problem that the working intensity of the workers is improved to a certain extent is solved.
