The structure with patent number CN210109409U includes a box cover and a box bottom fixed into a hollow cavity by a bolt assembly. Both ends of the insulation joint are provided with cable entry holes. The optical cable enters from one cable entry hole and passes through the other cable entry hole. A circular ring is fixed at each end surface of the box bottom near the box bottom in the cavity. The direction of the circular ring axis is consistent with the direction of the cable entry hole axis. The first grounding column screw, the first metal key, the first optical cable reinforcement core buckle, the plastic bracket, the second optical cable reinforcement core buckle, the second metal key, and the second grounding column screw are arranged in sequence between the circular rings. The utility model can achieve lightning protection and other functions, can cope with the test of severe weather, increase service life, and reduce the number of maintenance times, but the device still has areas that can be optimized.

[0004] The existing devices mainly adopt an upper and lower split box body structure, so that the joints of some box bodies run through the entire device, which makes it difficult to seal and fix some devices. At the same time, some devices mainly place optical cable connectors inside the box body, so that some devices can stably fix the two ends of the optical cable, which causes some optical cable connectors to be broken due to excessive force, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a sealed optical cable insulation joint is proposed. Utility Model Content

[0010] Preferably, a sealing screw sleeve is sleeved on the right side of the outer wall of the right sealing box, and the inner wall of the sealing screw sleeve can be threadedly sleeved on the first threaded outer wall and the second threaded outer wall.

[0011] Preferably, a wedge-shaped clamping block is fixedly connected to the left side of the fixed screw barrel, and a clamping screw sleeve is threadedly connected to the outer wall of the fixed screw barrel.

[0012] Preferably, a sealing ring is fixedly connected to the inner wall of the left sealing box side wall, and the inner wall of the sealing ring is attached to the outer wall of the left optical cable.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the sealing strip, the groove, the first thread, the second thread and the sealing screw sleeve in the sealing mechanism. By moving the left sealing box to fit the right sealing box, the left sealing box drives the sealing strip to be inserted into the groove of the right sealing box, and the first thread and the second thread are combined into a complete thread circle. Then, the sealing screw sleeve is rotated clockwise so that the sealing screw sleeve is sleeved on the outer wall of the first thread and the second thread, thereby realizing the sealing of the box body.

[0015] 2. The utility model inserts the left optical cable into the sealing ring of the left sealing box side wall through the structures of the fixed screw barrel, wedge-shaped clamping block, clamping screw sleeve and sealing ring in the clamping mechanism, and then rotates the clamping screw sleeve clockwise to make the clamping screw sleeve slide outward along the outer wall of the fixed screw barrel, and the clamping screw sleeve squeezes the wedge-shaped clamping block so that the outer end of the wedge-shaped clamping block shrinks and is pressed against the outer wall of the left optical cable, thereby achieving the clamping of the optical cable. This allows some devices to fix the optical cable on the side wall of the sealing box, which can effectively prevent the optical cable joint from being broken due to excessive force, thereby improving the stability and practicality of the device.
