Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: a waterproof and corrosion-resistant marine cable sealing device, including an outer housing 1, a rubber plate 2 is provided on the top of the outer housing 1, a swivel ring 10 is provided on the outside of the outer housing 1, anti-slip patterns are provided on the outside of the swivel ring 10, and a plurality of pull plates are provided at the swivel ring 10 to reduce the difficulty of rotating the swivel ring 10. A plurality of inner sleeve rods 13 are evenly provided on the inner side of the swivel ring 10, an outer sleeve tube 14 is provided on the outside of the inner sleeve rod 13, a first spring 11 is provided on the outside of the outer sleeve tube 14, a slide plate 5 is provided on one side of the outer sleeve tube 14, and a plurality of through grooves 3 are evenly provided on the inside of the outer housing 1. The outer sleeve tube 14 extends into the inside of the outer housing 1 through the through groove 3, and the first spring 11 is connected to the slide plate 5 and the swivel ring 10 respectively, so that the outer sleeve tube 14 enters the inside of the outer housing 1 and is connected to the slide plate 5;

[0022] A plurality of guide plates 6 are evenly provided inside the outer housing 1. Both sides of one end of the slide plate 5 and the guide plate 6 are made of inclined surface structures, and the slide plate 5 and the guide plate 6 are mutually adapted. During the movement of the slide plate 5, it can be guided through the inclined surface, so that a plurality of slide plates 5 clamp the outer wall of the cable. A plurality of slots 12 are evenly provided on the top of the swivel ring 10. An installation groove 19 is provided inside the outer housing 1. A second spring 17 is provided inside the installation groove 19. A plug rod 18 is provided at the bottom of the second spring 17. The bottom of the plug rod 18 is made of an arc structure. The plug rod 18 is mutually adapted to the slot 12. Under the guiding action of the arc surface, the plug rod 18 can be pressed out from the inside of the slot 12 under pressure, which is convenient for adjusting the position of the swivel ring 10. The plug rod 18 is mutually adapted to the slot 12;

[0023] A circular chute 7 is provided at the bottom outside the outer housing 1. A clamping ring 9 is provided inside the circular chute 7. A bevel guiding plate is provided at the bottom outside the outer housing 1, so that the clamping ring 9 can be sleeved into the circular chute 7 along the bevel guiding plate. An extension plate 16 is provided on one side of the clamping ring 9. Threaded holes 8 are provided at one ends of the two groups of extension plates 16. Connecting bolts 15 are provided inside the threaded holes 8. A groove 4 is provided at the bottom of the outer housing 1.

[0024] Working principle: During the plugging process, first place the cable inside the outer housing 1 and make the end of the cable closely adhere to the rubber plate 2. Then rotate the rotating ring 10. During the rotation of the rotating ring 10, the slot 12 applies pressure to the plug 18, forcing the plug 18 to disengage from the slot 12 and compressing the second spring 17 by the plug 18. Then the rotating ring 10 drives the inner sleeve rod 13 and the outer sleeve 14 to move. At this time, the outer sleeve 14 drives the sliding plate 5 to move. During the movement, the guiding plate 6 guides the sliding plate 5, so that the sliding plate 5 gradually moves towards the inside of the outer housing 1. The sliding plate 5 clamps the cable and fixes it inside the outer housing 1 so that it cannot be pulled out.

[0025] After the cable is clamped, continue to rotate the rotating ring 10. After moving to the specified position, the second spring 17 resets and drives the plug 18 to move, so that the plug 18 is reinserted into the slot 12. The rotating ring 10 cannot be rotated under the influence of external force. Then sleeve the clamping ring 9 along the bottom of the outer housing 1 into the circular chute 7. Then rotate the connecting bolt 15 to make the two groups of extension plates 16 approach each other, thereby applying pressure to the bottom end of the outer housing 1. Then the bottom end of the outer housing 1 deforms to fit the cable and fixes the cable secondly, thereby ensuring the fixing effect.
