DETAILED DESCRIPTION

[0026] The utility model is now further described in detail in connection with drawings and examples, these drawings are all simplified schematic diagram, just with schematic way to show the basic structure of the utility model, therefore it just shows the structure related to the utility model.

[0027] As Figure 1 Indicated, a kind of reusable cable plugging device, including: installing ring 3, the two plugging rings 1 of setting in installing ring 3 circumferential inner wall symmetry, and change gasket 2 of setting in the circumferential inner wall of symmetry two plugging rings 1.

[0028] The circumferential outer wall of the mounting ring 3 is provided with a plurality of mounting grooves 5, and each of the plurality of mounting grooves 5 is provided with a clamping assembly 4. The clamping assembly 4 comprises a threaded rod 401, a sliding block 403 arranged on the circumferential outer wall of the threaded rod 401, a fixed block 402 arranged on the circumferential outer wall of the threaded rod 401, a first expansion plate 404 arranged on the circumferential outer wall of the sliding block 403, and a second expansion plate 405 arranged on one side of the first expansion plate 404.

[0029] One end of the threaded rod 401 penetrates through one side of the mounting ring 3 and is located in the mounting groove 5. The one end of the threaded rod 401 is rotationally connected with the inner wall of one side of the mounting groove 5. The circumferential inner wall of the sliding block 403 is threadedly connected with the circumferential outer wall of the threaded rod 401. The circumferential inner wall of the fixed block 402 is rotationally connected with the circumferential outer wall of the threaded rod 401. One side of the fixed block 402 is rotationally connected with the inner wall of the other side of the mounting groove 5.

[0030] One side of the first expansion plate 404 is rotationally connected with the circumferential outer wall of the sliding block 403. The other side of the first expansion plate 404 is rotationally connected with one side of the second expansion plate 405. The other side of the second expansion plate 405 is rotationally connected with the circumferential outer wall of the fixed block 402. The circumferential outer wall of each of the two symmetrical blocking rings 1 is fixedly connected with a plurality of clamping blocks 9. The circumferential inner wall of the mounting ring 3 is provided with a plurality of clamping grooves 10.

[0031] It should be noted that the threaded rod 401, the sliding block 403, the fixed block 402, the first expansion plate 404 and the second expansion plate 405 in the clamping assembly 4 cooperate together. When the threaded rod 401 is rotated, the sliding block 403 will move along the threaded rod 401, push the first expansion plate 404 and the second expansion plate 405 to expand outward, so as to firmly fix the mounting ring 3 on the wall, so as to avoid the use of adhesives or other fixing materials, so that the device can be easily installed and disassembled, and is convenient for repeated use. The blocking ring 1 is connected with the clamping groove 10 of the mounting ring 3 through the clamping block 9. When it is necessary to replace the blocking ring 1 or adjust the blocking effect, the user only needs to simply remove the old blocking ring 1 and install the new blocking ring 1, so as to improve the flexibility and practicality of the device.

[0032] As shown in Figure 1 , the plurality of clamping blocks 9 are clamped with the corresponding plurality of clamping grooves 10 respectively. The circumferential outer wall of each of the two symmetrical blocking rings 1 is closely fitted with the circumferential inner wall of the mounting ring 3. The circumferential outer wall of the replacement gasket 2 is fixedly connected with a plurality of positioning blocks 7.

At the same time, the clamping of the positioning blocks 7 and the positioning holes 8 also ensures the stability and accuracy of the replacement gasket 2 in the sealing ring 1. The circumferential inner wall of the two symmetrical sealing rings 1 and the circumferential outer wall of the replacement gasket 2 are tightly fitted, which not only improves the sealing of the sealing, but also effectively prevents the cable from passing through or damaging the sealing gap, ensuring the stability and reliability of the sealing device during long-term use. And the non-slip pad 6 can increase the friction between the cable, preventing the cable from sliding or falling during the sealing process. This design not only improves the safety of the sealing device, but also prolongs its service life.

[0034] In use, a hole is drilled in the wall, and the threaded rod 401 is rotated to move the sliding block 403 along the threaded rod 401. With the movement of the sliding block 403, the first expansion plate 404 and the second expansion plate 405 will expand outward to tightly fit the wall, thereby fixing the mounting ring 3; the replacement gasket 2 is sleeved on the outer wall of the cable, and then the two symmetrical sealing rings 1 are wrapped around the replacement gasket 2, so that the plurality of positioning blocks 7 are clamped with the corresponding plurality of positioning holes 8; the clamping blocks 9 of the sealing ring 1 are aligned with the clamping grooves 10 on the inner wall of the mounting ring 3, and the sealing ring 1 is pushed so that the clamping blocks 9 are completely clamped into the clamping grooves 10, ensuring that the sealing ring 1 is tightly fitted with the mounting ring 3.
