The cable includes a main body with symmetrically mounted placement rings on its outer side. A first connector is connected to one end of the main body at a position corresponding to one of the placement rings, and a second connector is connected to one end of the main body at a position corresponding to the other placement ring. This invention features a scientifically sound and safe design. The first connector, second connector, placement rings, connecting buckle, and connecting buckle groove allow for adsorption connection, facilitating rapid installation between two cable bodies and easy assembly and splicing. The inclusion of a scratch-resistant mesh layer, elastic particles, and an RFC-shaped heat insulation layer enhances the cable's outer layer's protection against scratches and provides insulation against compression.

[0004] Based on the aforementioned patent, by setting a first connector, a second connector, a placement ring, a connecting buckle, and a connecting buckle groove, the connecting buckle at one end of the first connector is inserted into the connecting buckle groove at one end of the second connector, and the connecting buckle and the connecting buckle groove are connected by adsorption by an adsorption magnetic block, which can quickly install two cable bodies and facilitate the assembly and splicing of cable bodies. However, it can only connect a single cable. In view of this technical problem, this application proposes a quick connection device for cable splicing. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick connection device for cable splicing, comprising connecting sleeves on the left and right sides, each connecting sleeve having a rotating shaft rotatably connected to its inner wall, the rotating shaft being connected to an internal gear ring via a drive assembly, the outer wall of the internal gear ring being rotatably connected to the inner wall of the connecting sleeve, the inner wall of the internal gear ring having multiple second gears meshing with it, the second gears being connected to a fixing plate via a fixing assembly, each connecting sleeve having a conductive post fixedly connected to its inner wall, the conductive posts on the left and right sides having slots at opposite ends, the right end of the left conductive post being fixedly connected to a chuck, and the left end of the right conductive post being fixedly connected to a conductive disk, the chuck being connected to the conductive disk via a snap-fit ​​assembly.

[0007] Furthermore, the drive assembly includes a first gear fixedly connected to the outer wall of the shaft, the outer wall of the first gear meshing with the inner wall of the inner gear ring, and the inner wall of the shaft having an internal hexagonal groove.

[0008] Furthermore, the fixing component includes a connecting shaft fixedly connected to the inner wall of the second gear, the outer wall of the connecting shaft being rotatably connected to the inner wall of the connecting sleeve, a first bevel gear being fixedly connected to the outer wall of the connecting shaft, and a second bevel gear being meshed with the outer wall of the first bevel gear.

[0009] Furthermore, a screw is fixedly connected to the bottom end of the second bevel gear, the outer wall of the screw is rotatably connected to the inner wall of the connecting sleeve, a threaded sleeve is threadedly connected to the outer wall of the screw, the outer wall of the threaded sleeve is slidably connected to the inner wall of the connecting sleeve, and the outer side of the fixing plate is fixedly connected to the inner side of the threaded sleeve.

[0010] Furthermore, the snap-fit ​​assembly includes sliders slidably connected to the four sides of the inner wall of the conductive disk, and a snap-fit ​​block is fixedly connected to the left end of the slider, the snap-fit ​​block engaging with the chuck.

[0011] Furthermore, each of the card blocks is fixedly connected to a spring on its outer side, and the other end of each spring is fixedly connected to the inner wall of the connecting sleeve on the right side.

[0012] Furthermore, the outer wall of the connecting sleeve on the left is threaded with a sleeve, and the outer wall of the connecting sleeve on the right is provided with a threaded groove that mates with the sleeve.

[0013] This utility model has the following beneficial effects: 1.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a quick-connect cable splicing device, comprising connecting sleeves 1 on both the left and right sides. A rotating shaft 10 is rotatably connected to the inner wall of each connecting sleeve 1. A first gear 11 is fixedly connected to the outer wall of the rotating shaft 10. The outer wall of the first gear 11 meshes with the inner wall of an inner gear ring 12. An internal hexagonal groove 20 is formed on the inner wall of the rotating shaft 10. The outer wall of the inner gear ring 12 is rotatably connected to the inner wall of the connecting sleeve 1. Multiple second gears 13 are meshed with the inner wall of the inner gear ring 12. The inner walls of the second gears 13 are fixed... A connecting shaft 14 is connected, and the outer wall of the connecting shaft 14 is rotatably connected to the inner wall of the connecting sleeve 1. A first bevel gear 15 is fixedly connected to the outer wall of the connecting shaft 14. A second bevel gear 16 is meshed with the outer wall of the first bevel gear 15. A screw 17 is fixedly connected to the bottom end of the second bevel gear 16. The outer wall of the screw 17 is rotatably connected to the inner wall of the connecting sleeve 1. A threaded sleeve 18 is threadedly connected to the outer wall of the screw 17. The outer wall of the threaded sleeve 18 is slidably connected to the inner wall of the connecting sleeve 1. The outer side of the fixing plate 19 is fixedly connected to the inner side of the threaded sleeve 18.

[0019] Specifically, rotating the shaft 10 requires inserting an Allen wrench into the Allen socket 20. The screw 17 and the threaded sleeve 18 are connected by threads, thus having self-locking properties, which ensures that the fixing plate 19 will not loosen after fixing the cable. The connection between the cable and the connecting sleeve 1 can be secured by wrapping with waterproof tape and anti-static tape.

[0020] Reference Figure 1 , Figure 2 and Figure 4 The inner wall of the connecting sleeve 1 is fixedly connected with conductive posts 3. The opposite ends of the conductive posts 3 on the left and right sides are provided with slots 9. The right end of the conductive post 3 on the left side is fixedly connected with a chuck 4. The left end of the conductive post 3 on the right side is fixedly connected with a conductive disk 5. The inner wall of the conductive disk 5 is slidably connected with sliders 6. The left end of the slider 6 is fixedly connected with a locking block 7. The locking block 7 engages with the chuck 4. The outer side of the locking block 7 is fixedly connected with springs 8. The other end of the springs 8 is fixedly connected to the inner wall of the right connecting sleeve 1. The outer wall of the left connecting sleeve 1 is threadedly connected with a sleeve 2. The outer wall of the right connecting sleeve 1 is provided with a threaded groove that mates with the sleeve 2.

[0021] Specifically, the conductive post 3, chuck 4, conductive disk 5, locking block 7, and slider 6 are all made of copper and have electrical conductivity, thereby enabling the cables connected on both sides to be electrically connected. The copper ring fits into the slot 9. The outer ring on the right side of the chuck 4 is arc-shaped, so it can directly squeeze the locking block 7 to move outward. Thus, the inner side of the locking block 7 has a protruding part that can engage with the left side of the chuck 4.

[0022] Working principle: In use, first strip the insulation from the cables on both sides to expose the internal cables. Then, fit the copper rings onto the cables and insert them into the slots 9 on the left and right sides. Then, rotate the rotating shafts 10 on both sides, causing the rotating shafts 10 to drive the first gear 11 to rotate. The first gear 11 drives the internal gear ring 12 to rotate, which in turn drives the four-sided second gears 13 to rotate. The second gears 13 drive the connecting shaft 14 to rotate, which in turn drives the first bevel gear 15 to rotate. The first bevel gear 15 drives the second bevel gear 16 to rotate, which in turn drives the screw 17 to rotate. The screw 17 then moves the threaded sleeve 18 towards the center, causing the threaded sleeve 18 to... The fixing plate 19 is moved towards the center, thereby fixing the cable and preventing it from coming off the connecting sleeve 1. Then, the left chuck 4 is inserted into the inside of the right connecting sleeve 1, causing the chuck 4 to press the four side blocks 7 outwards. The blocks 7 compress the spring 8 and move on the conductive disk 5 via the slider 6. When the chuck 4 contacts the conductive disk 5, the spring 8 will spring the blocks 7 inwards, causing the blocks 7 to engage with the chuck 4, thus connecting the two connecting sleeves 1 together. Then, the sleeve 2 is rotated to the right connecting sleeve 1, covering the gap at the connection. Finally, the cables on the left and right sides are spliced.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
