[0025] Embodiment 1

[0026] Please refer to Figures 1 - 3 As shown, a cable sealing joint includes a front-end interface 1 and a rear-end interface 2;

[0027] The right side of the front-end interface 1 is installed with the left side of the rear-end interface 2. Installation grooves 8 are provided on the left side of the front-end interface 1 and the right side of the rear-end interface 2. A sealing cylinder 3 is installed inside the installation groove 8. A clamping component 6 is provided between the sealing cylinder 3 and the inside of the installation groove 8. A sealing gasket 7 is provided between the sealing cylinder 3 and the installation groove 8;

[0028] An inner cavity one 17 is provided on the right side inside the left installation groove 8, an inner cavity two 9 is provided on the left side inside the right installation groove 8, an inner groove 10 is provided on the left side inside the inner cavity two 9, and a clamping claw 11 is provided inside the inner groove 10; During operation, the cable passes through the inner cavity one 17 and the inner cavity two 9 so that it passes through the front-end interface 1 and the rear-end interface 2. After the front-end interface 1 and the rear-end interface 2 are installed, the cable is fixed by the clamping claw 11. Then, the sealing cylinder 3 and the sealing gasket 7 installed by the clamping component 6 seal between the left side of the front-end interface 1, the right side of the rear-end interface 2 and the cable, and isolate the air, thereby achieving the sealing effect.

[0029] On the right side of the outer surface of the front-end interface 1, there is an external thread 13. On the left side inside the rear-end interface 2, there is a threaded hole 12, and the threaded hole 12 is threadedly connected to the external thread 13. During operation, the front-end interface 1 and the rear-end interface 2 are stably installed through the threaded connection between the external thread 13 and the threaded hole 12.

[0030] At the center of the outer surface of the front-end interface 1, there is a sealing ring 14 fixedly connected. On the left side of the rear-end interface 2, there is a groove 16. The sealing ring 14 is inserted into the groove 16. Between the sealing ring 14 and the groove 16, there is a sealing ring 15, and the sealing ring 15 is located on the left side of the external thread 13. During operation, the threaded connection between the external thread 13 and the threaded hole 12 is sealed by inserting the sealing ring 14 and the sealing ring 15 into the groove 16, and rusting at the thread is avoided, so that the disassembly of the front-end interface 1 and the rear-end interface 2 during the replacement of the cable joint will not be affected.

[0031] On the left side of the outer surface of the front-end interface 1, there is a handle ring one 4 fixedly connected. On the left side of the outer surface of the rear-end interface 2, there is a handle ring two 5 fixedly connected, and both the handle ring one 4 and the handle ring two 5 are hexagonal. During operation, it is convenient to rotate the front-end interface 1 and the rear-end joint through the handle ring one 4 and the handle ring two 5.

[0032] The installation component includes card slots 601 opened on the upper and lower surfaces inside the installation groove 8. At the top and bottom of the sealing cylinder 3, there are sliding grooves 603. Inside the sliding grooves 603, there are sliding blocks 605 slidably connected. Between the sliding blocks 605 and the sliding grooves 603, there are springs 604 fixedly connected. On one side of the sliding block 605 away from the center inside the sealing cylinder 3, there is a clamping block 602 fixedly connected, and the outer surface of the clamping block 602 is clamped inside the card slot 601. During operation, when the sealing cylinder 3 is inserted into the installation groove 8, the clamping block 602 is squeezed. After the clamping block 602 is squeezed, it contracts by squeezing the sliding block 605 and the spring 604. Then, after the clamping block 602 contracts, the spring 604 is squeezed and has a rebounding force. When the sealing cylinder 3 is completely inserted into the installation groove 8, the clamping block 602 corresponds to the card slot 601. Immediately afterwards, the rebounding force of the spring 604 drives the clamping block 602 to move and be clamped inside the card slot 601, and the sealing cylinder 3 and the installation groove 8 are installed, so that the sealing cylinder 3 seals the ends of the front-end interface 1 and the rear-end interface 2. At the same time, when disassembling the sealing cylinder 3, move the sealing cylinder 3 so that the clamping block 602 is squeezed out of the card slot 601, and it is convenient to disassemble, repair and replace the sealing cylinder 3 and the sealing gasket 7.

[0033] The outer surface of the clamping block 602 and the inside of the card slot 601 are arc-shaped. During operation, it is convenient for the clamping block 602 to be clamped and disengaged from the card slot 601.
