Cavity wall is equipped with screw thread in sealing, and the sealing inner cavity is distinguished by two sealings and formed that the front end that two sealings are distinguished is equipped with mutual with inside
The elastic sealed body of connection, the optical cable sealing ring are built in sealed passage, and one end of optical cable sealing ring is against sealed passage
One end, squeeze locking stud and be tightened on sealed body by being threadedly engaged, the extrudings locking screw column outer wall equipped with screw thread,
It is made of two stud valves, two stud valves are mutually inserted along the axis of locking stud and buckle, and the inner wall of two stud valves merges
Constitute for the perforation across optical cable, the extrusion ring is two to distinguish formula structure, be located at optical cable sealing ring with squeeze locking stud it
Between.
The utility model compared with prior art, has the following advantages that and effect: the utility model binary channels internal screw thread is tight
Stationary cable sealing device structure is relatively simple, and sealed passage is arranged to two-flap type structure, so that facilitating U-shaped in installation process
Optical cable passes through sealing structure, and squeezes locking stud and squeeze flexible sealing ring, is not only locked more convenient, realizes fast
Speed installation is fixed, and guarantees leakproofness.
