[0032] Example:
[0033] like Figure 1-5As shown, this embodiment of a watertight cable joint waterproof sealing device includes a first joint 1 and a second joint 2 that mates with the first joint 1. A first annular sealing gasket 3 is fixedly connected to one end face of the first joint 1. A first fixing ring 4 is fixedly sleeved on the outer surface of the first joint 1. An annular plate 5 is fixedly connected to one end face of the first fixing ring 4. A second annular sealing gasket 6 is fixedly connected to the end face of the annular plate 5 away from the first fixing ring 4. A second fixing ring 7 is fixedly sleeved on the outer surface of the second joint 2. An annular groove 8 is formed on the second fixing ring 7. A third annular sealing gasket 9 is fixedly connected to the inner wall of the annular groove 8. A fourth annular sealing gasket 10 is fixedly connected to one end face of the second fixing ring 7. The outer surface of the first fixing ring 4 is fixedly connected to the fourth annular sealing gasket 10. Each of the four first connecting blocks 11 has a threaded fastening bolt 12. The outer surface of the second fixing ring 7 is fixedly connected to four second connecting blocks 13. One end of the second connector 2 is inserted into the first connector 1, so that the four first connecting blocks 11 are respectively engaged with the four second connecting blocks 13. Each of the four second connecting blocks 13 has a threaded hole 14. Using the corresponding tool, the four fastening bolts 12 are tightened so that the four fastening bolts 12 are respectively threaded into the four threaded holes 14. Then, four nuts are used to thread the four nuts onto the four fastening bolts 12, so that the four nuts are respectively engaged with the four second connecting blocks 13. This completes the connection and installation between the first connector 1 and the second connector 2.
[0034] like Figure 4 As shown, one end of the second connector 2 is inserted into the first connector 1, and the first annular sealing gasket 3 is tightly fitted to the outer surface of the second connector 2 to ensure the sealing of the connection between the first connector 1 and the second connector 2.
[0035] like Figure 2 , Figure 3 and Figure 5 As shown, the annular plate 5 and the second annular sealing gasket 6 are both located in the annular groove 8, and the second annular sealing gasket 6 and the third annular sealing gasket 9 are tightly fitted together.
[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the outer surface of the annular plate 5 is in contact with the inner surface of the annular groove 8.
[0037] like Figure 2 As shown, the fourth annular sealing gasket 10 is tightly fitted with the first fixing ring 4. Through the combined use of the first annular sealing gasket 3, the second annular sealing gasket 6, the third annular sealing gasket 9 and the fourth annular sealing gasket 10, multiple sealing effects can be achieved, resulting in higher waterproof performance and ensuring the actual use effect of the subsequent first connector 1 and second connector 2.
[0038] like Figure 2 and Figure 3As shown, the four first connecting blocks 11 and the four second connecting blocks 13 are arranged in a ring at equal angles. The four first connecting blocks 11 are respectively fitted with the four second connecting blocks 13, and the threaded holes 14 are adapted to the fastening bolts 12.
[0039] like Figure 2 As shown, the inner surface of the fourth annular sealing gasket 10 is in contact with the outer surface of the annular plate 5. When the first connector 1 and the second connector 2 are used, the fourth annular sealing gasket 10 can achieve a good sealing effect on the outer side of the first connector 1 and the second connector 2, preventing water from directly contacting the annular plate 5.
[0040] Specifically, when using this watertight cable joint waterproof sealing device: insert one end of the second connector 2 into the first connector 1, so that the four first connecting blocks 11 are respectively in contact with the four second connecting blocks 13. At this time, the first annular sealing gasket 3 is tightly in contact with the second connector 2, the annular plate 5 and the second annular sealing gasket 6 are both located in the annular groove 8, the outer wall of the annular plate 5 is in contact with the inner surface of the annular groove 8, the second annular sealing gasket 6 is tightly in contact with the third annular sealing gasket 9, and the fourth annular sealing gasket 10 is in contact with one side surface of the first fixing ring 4. At the same time, the inner surface of the fourth annular sealing gasket 10 is in contact with the outer surface of the annular plate 5. Then, use the corresponding tools to tighten the four fastening bolts 12. The four fastening bolts 12 are threaded into the four threaded holes 14, and then four nuts are threaded onto the four fastening bolts 12, so that the four nuts fit into the four second connecting blocks 13. This completes the connection between the first connector 1 and the second connector 2, ensuring the tightness of the connection between the first connector 1 and the second connector 2 and preventing easy loosening. Through the combined use of the first annular sealing gasket 3, the second annular sealing gasket 6, the third annular sealing gasket 9, and the fourth annular sealing gasket 10, multiple sealing effects can be achieved, resulting in higher waterproof performance and ensuring the actual use effect of the first connector 1 and the second connector 2, thus improving their service life.
