[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a cable with waterproof ends, comprising:

[0031] A cable body 1, a port tube 2 is fixedly connected to the front end of the cable body 1, a fixed shell 3 is fixedly connected to the outer wall of the pressing rod 6, air inlets 5 are opened at both left and right ends of the outer wall of the fixed shell 3, the bottom end of the fixed shell 3 is fixedly connected to the outer wall of the top end of the port tube 2, first springs 15 are fixedly connected to both left and right sides of the bottom end of the piston plate 14, and the other ends of the first springs 15 are respectively fixedly connected to both left and right sides of the outer wall of the top end of the port tube 2.

[0032] Specifically: During the cable assembly process, first, the cable body 1 is fixed in place, and then another section of the cable is docked into the inside of the port tube 2. This operation involves inserting the end of the cable body 1 into the port tube 2 to ensure that the two sections of the cable are tightly connected, forming a stable electrical and mechanical connection.

[0033] Referring to Figure 3 and Figure 4 , a threaded tube 7, an adjusting tube 4 is threadedly connected to the front end of the threaded tube 7, connecting rods 12 are rotatably connected to the inner walls of the opposite ends of the adapter blocks 11, a connecting ring 10 is rotatably connected to the inner wall of the adjusting tube 4, the opposite ends of the adapter blocks 11 are fixedly connected to the inner wall of the connecting ring 10, clamping claws 13 are rotatably connected to the front sides of the opposite ends of the connecting rods 12, and the opposite ends of the clamping claws 13 are rotatably connected to the outer wall of the adapter ring 8.

[0034] Specifically: After the cable is docked into the port tube 2, by rotating the adjusting tube 4, it moves along the thread of the threaded tube 7. During the movement of the threaded tube 7, the connecting ring 10 is driven, so that the adapter block 11 pushes the connecting rod 12 to move, and the connecting rod 12 further drives the clamping claws 13 to fix the cable. In this process, by rotating the adjusting tube 4, it is ensured that the clamping claws 13 contract or expand appropriately according to the diameter of the docked cable, realizing the stable clamping and fixing of the cable. In practical applications, this design allows the adjusting tube 4 to be flexibly adjusted according to cables of different diameters, thus ensuring reliable connections between cables of different specifications. The contraction or expansion function of the clamping claws 13 not only improves the assembly accuracy, but also ensures the firmness and tightness of the cable connection. In addition, it can reduce the mechanical stress concentration caused by the difference in cable diameters, further enhancing the durability and reliability of the overall system.

[0035] Refer to Figure 5 and Figure 6 As shown in FIGS. Figure 5 and Figure 6 , for the inflatable airbag 9, a communication pipe 16 is fixedly connected to the outer wall of the top end of the inflatable airbag 9. A first fixing ring 19 is fixedly connected to the top inner wall of the communication pipe 16. The inflatable airbag 9 is fixedly connected to the inner wall of the port pipe 2. A dredging pipe 18 is fixedly connected to the outer wall of the bottom end of the inflatable airbag 9. The top outer wall of the threaded plug 17 is detachably connected to the bottom inner wall of the dredging pipe 18. Second springs 20 are fixedly connected to both the left and right sides of the bottom end of the first fixing ring 19. The other ends of the second springs 20 are fixedly connected to the opposite ends of the closing plate 21. Second fixing rings 22 are rotatably connected to the opposite ends of the closing plate 21. The bottom ends of the support columns 23 are respectively fixedly connected to the four sides of the top of the second fixing rings 22.

[0036] Specifically: After the cables are butted, by pressing the pressing rod 6, the piston plate 14 introduces external air into the fixed housing 3 through the air inlet 5. During this process, the first spring 15 assists the user to push the piston plate 14 so as to repeatedly input air, gradually increasing the air pressure in the communication pipe 16. When the air pressure exceeds the pulling force exerted by the second spring 20 on the closing plate 21, the air will pass through the closing plate 21 and flow into the inflatable airbag 9. As the airbag inflates and expands, it will gradually adhere to the surface of the cable, thereby forming a tight seal between the cables, preventing moisture from seeping into the port pipe 2, improving the waterproof effect between the cable body 1 and other cables, and ensuring the reliability and durability of the connection. If there is too much air in the inflatable airbag 9, the threaded plug 17 can be rotated to disconnect it from the dredging pipe 18, so that the air in the inflatable airbag 9 will be discharged through the dredging pipe 18, achieving the effect of deflation. This controllable deflation design enables the user to precisely adjust the inflation degree of the airbag, ensuring the sealing and stability of the cable connection, and at the same time avoiding problems such as excessive pressure or seal failure that may be caused by over-inflation.

[0037] Working principle: When assembling and fixing the cable body 1 of the cable, another section of cable is butted inside the port tube 2 to assemble the cable body 1 and the cable. After the cable is butted in the port tube 2, rotate the adjusting tube 4 to move it along the threaded tube 7, so that the threaded tube 7 drives the connecting ring 10, and the adapter block 11 drives the connecting rod 12 to move, and the connecting rod 12 drives the clamping claws 13 to fix the cable, so that the adjusting tube 4 fixes the cable, and the clamping claws 13 contract according to the diameter of the butted cable, so that the cables are assembled. After the cables are butted, press the pressing rod 6 to make the piston plate 14 enter the outside air into the fixed housing 3 through the air inlet 5. The first spring 15 can assist the user to repeatedly input air into the piston plate 14. The air pressure in the connecting pipe 16 increases, so that the pressure exceeds the pulling effect of the second spring 20 on the closing plate 21, and the air passes through the closing plate 21 and flows into the expansion airbag 9, so that the expansion airbag 9 expands and clings to the cable, making the connection between the cables airtight, preventing water from entering the port tube 2, and improving the waterproof effect between the cable body 1 and other cables. When there is too much air, rotate the threaded plug 17 to make it fall off from the dredging tube 18, and the air in the expansion airbag 9 is discharged from the dredging tube 18 to achieve the air release effect.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
