[0024] Beneficial effects of the present invention:

[0025] 1. In the present invention, after one end of the two cable bodies to be connected is passed through the anti-dropping component and the positioning sleeve, the cable core is inserted into the metal sleeve of the connecting insulating tube so that the outer peripheral walls of the cable cores at both ends are in contact with the inner wall of the metal sleeve. After the cable cores at both ends are in contact with each other, the rotating block of the protective component is opened to rotate the adjusting hand wheel, and the corresponding adjusting hand wheel is rotated to drive the disc to rotate along the connecting insulating tube, and the pushing block is pushed to move to the side away from the connecting insulating tube through the nut end of the adjusting hand wheel. The moving pushing block drives the insulating block and the semicircular block to move synchronously, so that the semicircular block and the insulating block slide along the U-shaped groove, so that the semicircular block and the conical block squeeze the cable core, so that the cable core and the metal sleeve are tightly pressed together, and the electrical connection of the cable core is completed, which simplifies the cable connection process, improves the connection efficiency, ensures the stable transmission of current or signals between cables, and facilitates the rapid disassembly and installation of the cable body.

[0026] When the adjusting hand wheel is opened, the chamfering block is separated from the C-shaped block by pulling the lever, and the rotating block can be pulled to rotate along the rotating shaft to open, which is convenient for the rotation opening and locking of the rotating block and the rotation use of the adjusting hand wheel. At the same time, the adjusting hand wheel is protected by the rotating block and the protective block, which reduces the risk of loose connection or failure caused by accidental contact with the adjusting hand wheel during the installation process after the cable body is connected, thereby ensuring the stability and reliability of the connection between the cable body and the connecting insulating tube.

[0027] 3. In the present invention, the positioning sleeve is pushed to slide along the outer wall of the cable body, and the positioning sleeve is abutted against the side wall of the clamp through the sealing ring. At this time, the corresponding claw is inserted into the inside of the slot, and the threaded end of the rotating fastening wheel is abutted against the outer peripheral wall of the positioning sleeve, so that the claw is tightly pressed against the slot to complete the clamping of the positioning sleeve and the clamp. When the positioning sleeve moves, the anti-drop assembly is driven to move synchronously, which prevents the cable body from loosening or falling off during the connection process, improves the stability and reliability of the connection, and the positioning sleeve and the clamp are sealed by the sealing ring to prevent external factors such as moisture and dust from invading the cable connection, thereby ensuring the sealing and safety of the cable connection.

[0028] 4. In the present invention, the restoring force of the spring is used to push the card block and the positioning groove of the arc-shaped card belt to be clamped and fixed, so that the two rubber pads are tightly pressed against the outer wall of the cable body. When the cable body moves to the side away from the connecting insulating tube, the arc block is driven by the tensile block to slide along the bracket, and the arc block drives the folding block to rotate along the rotating rod, so that the second anti-slip block moves upward to further squeeze the cable body, making it more secure when the cable body is pulled to move to both sides, thereby improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body and the connecting parts, improving the stability and anti-slip performance of the cable connection, effectively resisting external forces, preventing the cable from falling off, facilitating installation and maintenance, and preventing the cable body from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failures and improving the safety performance of the overall system.

[0029] 5. In the present invention, the outer sheath resists physical damage and chemical corrosion in the external environment of the cable body and protects the internal structure from being affected. The armor layer improves the mechanical strength of the cable body, so that it can withstand stronger external forces and pressures and is suitable for harsher working environments. The design of the insulating layer ensures electrical isolation between cable cores, reduces the risk of current leakage and short circuit, and ensures that the electrical performance of the cable is stable and reliable. The filling of fillers reduces the gaps between cable cores, avoids internal stress concentration when the cable is bent or moved, and protects the integrity of the cable core and the insulation layer. The outer sheath, armor layer and inner sheath together constitute a multiple protection system for the cable, which effectively prevents the external environment from damaging the internal structure of the cable and extends the service life of the cable.

A frame 719 is fixedly provided on the outer wall of the fixed block 715, and the other end of the spring 718 is fixedly connected to the inner wall of the frame 719; the restoring force of the spring 718 pushes the clamping block 716 to be clamped and fixed to the positioning groove 714 of the arc-shaped card belt 713.

[0060] When using the anti-slip assembly 7, while completing the installation of the positioning sleeve 602, the first anti-slip block 701 is driven to move synchronously, so that the first anti-slip block 701 is clamped with the outer wall of the cable body 2 through the arc groove 703, and then one of the tensile blocks 704 is rotated and opened along the other tensile block 704, so that the outer wall of the cable body 2 is in contact with the inner wall of one of the rubber pads 705, and then the other tensile block 704 is rotated in the opposite direction to make the inner wall of the other rubber pad 705 clamped with the cable body 2, and at this time, the tensile block 704 is pulled to move to the side away from the first anti-slip block 701. During the movement, the tensile block 704 at the lower end drives one of the second hinge seats 708 to move synchronously, so that the arc block 707 slides along the bracket 706;

[0061] The arc block 707 drives another second hinge seat 708 to move, so that the folding block 709 rotates along the rotating rod 710, and the rotating folding block 709 pushes the third hinge seat 712 to move upward, so that the second anti-slip block 702 slides along the first anti-slip block 701, so that the second anti-slip block 702 squeezes and fixes the outer peripheral wall of the cable body 2 through the arc groove 703. After the second anti-slip block 702 is moved to a suitable use height, the arc cassette 713 is inserted into the fixed block 715. At this time, the arc cassette 713 squeezes the card block 716 and slides outward along the fixed block 715. At this time, the spring 718 is compressed, so that the arc cassette 713 moves to a suitable position;

[0062] Through the restoring force of spring 718, the card block 716 is pushed to be fixed with the positioning groove 714 of the arc-shaped card belt 713, so that the two rubber pads 705 are tightly pressed against the outer wall of the cable body 2. When the cable body 2 moves to the side away from the connecting insulating tube 1, the arc block 707 is driven by the tensile block 704 to slide along the bracket 706, and the arc block 707 drives the folding block 709 to rotate along the rotating rod 710, so that the second anti-slip block 702 moves upward to further squeeze the cable body 2, making it more secure when the cable body 2 is pulled to move to both sides, thereby improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body 2 and the connecting parts, improving the stability and anti-slip performance of the cable connection, effectively resisting external forces, preventing the cable from falling off, facilitating installation and maintenance, preventing the cable body 2 from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failures, and improving the safety performance of the overall system.

[0063] Embodiment 4

[0064] like Figure 1 and Fig.12 As shown, this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the cable body 2 includes an outer protective layer 9, an armor layer 10 is fixedly provided on the inner wall of the outer protective layer 9, an inner protective layer 11 is fixedly provided on the inner wall of the armor layer 10, an insulating layer 12 is fixedly provided inside the inner protective layer 11, a plurality of cable cores 3 are located inside the insulating layer 12, and fillers 13 are filled in the gaps between the plurality of cable cores 3 and between the cable cores 3 and the insulating layer 12.

[0065] The outer sheath 9 resists physical damage and chemical corrosion in the external environment of the cable body 2 and protects the internal structure from being affected. The armor layer 10 improves the mechanical strength of the cable body 2, enabling it to withstand stronger external forces and pressures and be suitable for harsher working environments. The design of the insulating layer 12 ensures electrical isolation between the cable cores 3, reduces the risk of current leakage and short circuit, and ensures that the electrical performance of the cable is stable and reliable. The filling of the filler 13 reduces the gaps between the cable cores 3, avoids internal stress concentration when the cable is bent or moved, and protects the integrity of the cable core 3 and the insulating layer 12. The outer sheath 9, armor layer 10 and inner sheath 11 together constitute a multiple protection system for the cable, which effectively prevents the external environment from damaging the internal structure of the cable and extends the service life of the cable.

[0066] Working principle:

[0067] When in use, firstly, one end of the two cable bodies 2 to be connected is passed through the anti-dropping component 7 and the positioning sleeve 602, and then the cable core 3 is inserted into the metal sleeve 4 of the connecting insulating tube 1, so that the outer peripheral walls of the cable core 3 at both ends are in contact with the inner wall of the metal sleeve 4. After the cable cores 3 at both ends are in contact with each other, the rotating block 802 of the protective component 8 is opened to rotate the adjusting hand wheel 504, and the corresponding adjusting hand wheel 504 is rotated to drive the disc 505 to rotate along the connecting insulating tube 1, and the push block 503 is pushed by the nut end of the adjusting hand wheel 504. Move to the side away from the connecting insulating tube 1, the moving push block 503 drives the insulating block 502 and the semicircular block 501 to move synchronously, so that the semicircular block 501 and the insulating block 502 slide along the U-shaped groove 506, so that the semicircular block 501 and the conical block 507 squeeze the cable core 3, so that the cable core 3 and the metal sleeve 4 are tightly pressed together, and the electrical connection of the cable core 3 is completed, which simplifies the cable connection process, improves the connection efficiency, ensures the stable transmission of current or signal between cables, and facilitates the rapid disassembly and installation of the cable body 2;

[0068] After adjusting the adjusting hand wheel 504 to a suitable position, the rotating block 802 is pushed to rotate along the rotating shaft 803. At this time, the chamfering block 806 is perpendicular to the rotating block 802 due to the tension of the tension spring 807. As the rotating block 802 moves, the rotating block 802 is driven to move synchronously. When the chamfering block 806 contacts the outer wall of the C-shaped block 805, the chamfering block 806 is pushed to rotate along the rotating block 802. At this time, the tension spring 807 is stretched. When the rotating block 802 contacts the protective block 801, the restoring force of the tension spring 807 makes the chamfering block 806 plug into the C-shaped block 805 to fix the rotating block 802.

[0069] When it is necessary to open the rotating block 802 and rotate the adjusting handwheel 504, after pulling the lever 804 to drive the chamfering block 806 to separate from the C-shaped block 805, the rotating block 802 can be pulled to rotate and open along the rotating shaft 803, which facilitates the rotation opening and locking of the rotating block 802 and the rotation use of the adjusting handwheel 504. At the same time, the adjusting handwheel 504 is protected by the rotating block 802 and the protective block 801, reducing the risk of loose connection or failure due to accidental contact with the adjusting handwheel 504 during the installation process after the cable body 2 is connected, thereby ensuring the stability and reliability of the connection between the cable body 2 and the connecting insulating tube 1.

[0070] After the cable core 3 is connected, the positioning sleeve 602 is pushed to slide along the outer wall of the cable body 2, and the positioning sleeve 602 is abutted against the side wall of the clamp 601 through the sealing ring. At this time, the corresponding claw 604 is inserted into the inside of the slot 605, and the threaded end of the rotating fastening wheel 606 is abutted against the outer wall of the positioning sleeve 602, so that the claw 604 and the slot 605 are tightly pressed together to complete the clamping of the positioning sleeve 602 and the clamp 601. When the positioning sleeve 602 moves, the anti-drop assembly 7 is driven to move synchronously to prevent the cable body 2 from loosening or falling off during the connection process, thereby improving the stability and reliability of the connection. The positioning sleeve 602 and the clamp 601 are sealed by a sealing ring to prevent external factors such as moisture and dust from invading the cable connection, thereby ensuring the sealing and safety of the cable connection.

[0071] When using the anti-slip assembly 7, while completing the installation of the positioning sleeve 602, the first anti-slip block 701 is driven to move synchronously, so that the first anti-slip block 701 is clamped with the outer wall of the cable body 2 through the arc groove 703, and then one of the tensile blocks 704 is rotated and opened along the other tensile block 704, so that the outer wall of the cable body 2 is in contact with the inner wall of one of the rubber pads 705, and then the other tensile block 704 is rotated in the opposite direction to make the inner wall of the other rubber pad 705 clamped with the cable body 2, and at this time, the tensile block 704 is pulled to move to the side away from the first anti-slip block 701. During the movement, the tensile block 704 at the lower end drives one of the second hinge seats 708 to move synchronously, so that the arc block 707 slides along the bracket 706;

[0072] The arc block 707 drives another second hinge seat 708 to move, so that the folding block 709 rotates along the rotating rod 710, and the rotating folding block 709 pushes the third hinge seat 712 to move upward, so that the second anti-slip block 702 slides along the first anti-slip block 701, so that the second anti-slip block 702 squeezes and fixes the outer peripheral wall of the cable body 2 through the arc groove 703. After the second anti-slip block 702 is moved to a suitable use height, the arc cassette 713 is inserted into the fixed block 715. At this time, the arc cassette 713 squeezes the card block 716 and slides outward along the fixed block 715. At this time, the spring 718 is compressed, so that the arc cassette 713 moves to a suitable position;

[0073] Through the restoring force of spring 718, the card block 716 is pushed to be fixed with the positioning groove 714 of the arc-shaped card belt 713, so that the two rubber pads 705 are tightly pressed against the outer wall of the cable body 2. When the cable body 2 moves to the side away from the connecting insulating tube 1, the arc block 707 is driven by the tensile block 704 to slide along the bracket 706, and the arc block 707 drives the folding block 709 to rotate along the rotating rod 710, so that the second anti-slip block 702 moves upward to further squeeze the cable body 2, making it more secure when the cable body 2 is pulled to move to both sides, thereby improving the stability and anti-slip effect of the connection, enhancing the fixing effect between the cable body 2 and the connecting parts, improving the stability and anti-slip performance of the cable connection, effectively resisting external forces, preventing the cable from falling off, facilitating installation and maintenance, preventing the cable body 2 from accidentally falling off or loosening, thereby avoiding safety accidents that may be caused by cable failures, and improving the safety performance of the overall system.

[0074] The outer sheath 9 resists physical damage and chemical corrosion in the external environment of the cable body 2 and protects the internal structure from being affected. The armor layer 10 improves the mechanical strength of the cable body 2, enabling it to withstand stronger external forces and pressures and be suitable for harsher working environments. The design of the insulating layer 12 ensures electrical isolation between the cable cores 3, reduces the risk of current leakage and short circuit, and ensures that the electrical performance of the cable is stable and reliable. The filling of the filler 13 reduces the gaps between the cable cores 3, avoids internal stress concentration when the cable is bent or moved, and protects the integrity of the cable core 3 and the insulating layer 12. The outer sheath 9, armor layer 10 and inner sheath 11 together constitute a multiple protection system for the cable, which effectively prevents the external environment from damaging the internal structure of the cable and extends the service life of the cable.
