[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: A double coaxial connector for a bundled cable, including a main pipe 1, a plurality of fixed rods 2 are fixedly connected inside the main pipe 1, one ends of the plurality of fixed rods 2 away from the main pipe 1 are fixedly connected with a fixed plate 3, a threaded rod 4 is rotatably connected inside the fixed plate 3, an internal thread sleeve 5 is threadedly connected to the outer surface of the threaded rod 4, a limiting sleeve 6 is fixedly connected to one side of the internal thread sleeve 5, a limiting rod 7 is fixedly connected to one side of a fixed rod 2 close to the internal thread sleeve 5, and the outer surface of the limiting rod 7 is movably embedded inside the limiting sleeve 6. A connecting plate 8 is arranged on the side of the internal thread sleeve 5 away from the threaded rod 4, a needle core 9 is fixedly connected to the side of the connecting plate 8 away from the internal thread sleeve 5, a stabilizing cylinder 10 is fixedly embedded on the inner surface of the main pipe 1, and the outer surface of the needle core 9 is movably embedded inside the stabilizing cylinder 10. The driving bevel gear 12 that rotates with the power rod 14 will drive the driven bevel gear 13 under the meshing action, and make the threaded rod 4 rotate inside the fixed plate 3.

[0026] Such as Figures 1 to 5As shown, a spring 11 is movably sleeved on the outer surface of the needle core 9. One end of the spring 11 away from the stabilizing cylinder 10 is fixedly connected to one side of the connecting plate 8, and the other end of the spring 11 away from the connecting plate 8 is fixedly connected to one side of the stabilizing cylinder 10. Compressing the spring 11 gives the spring 11 elastic potential energy. When the internal thread sleeve 5 retracts, it will drive the connecting plate 8 to retract as well.

[0027] As Figures 1 to 5 shown, one end of the threaded rod 4 away from the internal thread sleeve 5 is fixedly connected to a driving bevel gear 12. The outer surface of the driving bevel gear 12 is meshed with a driven bevel gear 13. The rotating driving bevel gear 12 will drive the driven bevel gear 13 under the meshing action.

[0028] As Figures 1 to 5 shown, a power rod 14 is fixedly embedded inside the driven bevel gear 13. The outer surface of the power rod 14 is rotatably connected inside the main pipe 1 and extends out at one end. One end of the power rod 14 that extends out is fixedly connected to a rotating rod 15. Through the rotating rod 15, the power rod 14 rotates inside the main pipe 1.

[0029] As Figures 1 to 5 shown, a threaded groove 16 is formed on the inner surface of the main pipe 1. The outer surface of the main pipe 1 is fixedly sleeved with a main housing 17. The connecting pipe is preliminarily connected to the main pipe 1 through the threaded groove 16.

[0030] As Figures 1 to 5 shown, a plurality of clamping rods 18 are rotatably connected inside the main housing 17. A rod sleeve 19 is movably sleeved on the outer surface of the clamping rods 18. One side of a plurality of rod sleeves 19 is rotatably connected to a first fixing ring 20. When the two fixing rings rotate, they will drive the rod sleeves 19 inside and cause the clamping rods 18 inside the rod sleeves 19 to swing.

[0031] As Figures 1 to 5 shown, a plurality of follower rods 21 are fixedly connected to one side of the first fixing ring 20 close to the rod sleeve 19. One end of the plurality of follower rods 21 away from the first fixing ring 20 is fixedly connected to a second fixing ring 22. A plurality of spiral teeth 23 are fixedly connected to the outer surface of the second fixing ring 22. The outer surfaces of the plurality of spiral teeth 23 are meshed with a worm 24. Under the meshing action of the worm 24 on the spiral teeth 23, the first fixing ring 20, the follower rods 21 and the second fixing ring 22 will also rotate.

[0032] As Figures 1 to 5 shown, the outer surface of the worm 24 is rotatably connected inside the main housing 17 and extends out at one end. One end of the worm 24 that extends out is fixedly connected to a knob 25. The worm 24 can be rotated inside the main housing 17 through the knob 25.

[0033] Working principle: First, pre-align the needle core 9 with the connecting device. Then, through the rotating rod 15, rotate the power rod 14 inside the main pipe 1. The driving bevel gear 12 that rotates with the power rod 14 will drive the driven bevel gear 13 under the meshing action, and make the threaded rod 4 rotate inside the fixed plate 3. The fixed plate 3 is connected inside the main pipe 1 through the fixed rod 2. The rotating thread will drive the internal thread sleeve 5. The limit sleeve 6 can only move along the axis direction of the limit rod 7. So the rotating thread will make the internal thread sleeve 5 move along the axis direction of the limit rod 7 and compress the spring 11, making the spring 11 have elastic potential energy. When the internal thread sleeve 5 retracts, it will drive the connecting plate 8 to retract as well. During the movement, it will push the connecting plate 8 and the needle core 9, making the needle core 9 extend outwards inside the stable cylinder 10 and embed into the connecting device to complete the connection, which can effectively compensate for the connection deviation. During the actual installation and use process, there may be position deviations between the connecting components, and it can automatically adjust the position to make up for this deviation, thus ensuring a good connection and being able to adapt to different connection depth requirements. Then, initially connect the connecting pipe to the main pipe 1 through the thread groove 16. Next, through the knob 25, rotate the worm 24 inside the main housing 17. Under the meshing action of the worm 24 on the worm teeth 23, the first fixing ring 20, the follower rod 21, and the second fixing ring 22 will also rotate. When the two fixing rings rotate, they will drive the rod sleeve 19 inside them, and make the clamping rod 18 inside the rod sleeve 19 swing. When the three clamping rods 18 swing simultaneously, they will further clamp and fix the internal main pipe 1 and the connecting pipe, which can effectively prevent the pipeline from loosening or falling off when subjected to external forces. The seal at the connection can fit tightly, thereby enhancing the abilities of waterproof, dustproof, and gas leakage prevention, and being convenient for installation and disassembly.

[0034] The above are only the preferred embodiments of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
