[0002] The main function of the fiber optic splice box is to split the optical cable into single optical fibers, which is installed on the wall, cable, pole or sewer. Its function is to provide the fusion splicing of optical fibers, the fusion splicing of optical fibers and pigtails, and the handover of optical connectors. The fiber optic splice box is mainly suitable for the straight-through and branching connections of various structural optical cables in the aerial, pipeline, direct burial and other laying methods. After the optical cable enters the fiber optic splice box, its outer sheath and reinforcing core must be mechanically fixed, the ground wire protection component must be installed, the end protection treatment must be performed, and the optical fibers must be grouped and protected.

[0003] Among them, the prior art generally adopts the following technical solutions to fix the optical fiber splice box: Figure 11-15 As shown, the optical fiber splice box sealing assembly includes two conventional circular holes. At the same time, the optical fiber splice box sealing assembly is specially used for digging and splicing optical cables, so its assembly must be divided into two parts, an upper shell and a lower shell, which are separated from each other (such as Fig.15 ), the two parts are installed by splicing, so the optical fiber splice box sealing assembly in the prior art has the following defects:
