DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 4 A cable with a long service life comprises a connecting frame 2, a guide plate 3 and two cable bodies 1, a connecting frame 2 is provided at the bottom of the connecting frame 2 with a slide groove 13, two connecting frames 4 are slidably connected in the slide groove 13, the bottoms of the two connecting frames 4 are welded with connecting frames 3 5, the outer sides of the connecting frame 3 5 are slidably connected with two clamping frames 6, the two cable bodies 1 are plugged in and fixed by the clamping frames 6, a bidirectional threaded rod 16 is rotatably connected in the connecting frame 3 5, and the bidirectional threaded rod 16 passes through the clamping frame 6 and is threadedly connected to the clamping frame 6, two guide grooves 10 are provided on the upper surface of the guide plate 3, guide columns 7 are welded on the tops of the two connecting frames 4, and the guide columns 7 are slidably connected to the guide grooves 10, a slide groove 9 is provided on the upper surface of the guide plate 3, a fixing plate 11 is slidably connected in the slide groove 9, and the upper surface of the fixing plate 11 is provided with There is a rotating hole, in which a threaded frame 12 is rotatably connected. A threaded hole is provided on the upper surface of the connecting frame 2, and the threaded frame 12 is threadedly connected to the threaded hole. The two cable bodies 1 are plugged in, and then the bidirectional threaded rod 16 is rotated. The bidirectional threaded rod 16 drives the clamping frame 6 to move toward each other, so that the clamping frame 6 clamps and fixes the cable body 1. When the clamping frame 6 completes the clamping and fixing of the cable body 1, the rotation of the bidirectional threaded rod 16 is stopped, and then the guide plate 3 is pulled. During the movement of the guide plate 3, the guide column 7 will drive the connecting frame 2 4 to move toward each other along the slide groove 2 13 under the action of the guide groove 10, and the connecting frame 2 4 drives the connecting frame 3 5 to move toward each other, and the connecting frame 3 5 drives the clamping frame 6 to move toward each other, so that the two cable bodies 1 fit more closely, avoiding the separation of the connection between the two cables, and improving the stability of the cable connection.

[0025] In the present invention, two connecting rods 20 are welded to the outer side of the threaded frame 12, and two sliding tubes 19 are welded to the upper surface of the fixing plate 11. A clamping frame 18 is slidably connected in the two sliding tubes 19, and the connecting rod 20 is clamped with the clamping frame 18. A spring 17 is welded at the bottom of the clamping frame 18, and the spring 17 is fixed to the fixing plate 11. Press the clamping frame 18 to move the clamping frame 18 into the sliding tube 19 and squeeze the spring 17, and then rotate the threaded frame 12. When the threaded frame 12 rotates to the bottom of the threaded hole, the connecting rod 20 is still in the previous position. At this time, the clamping frame 18 is released, and the clamping frame 18 is reset under the action of the spring 17, so that the clamping frame 18 is clamped with the connecting rod 20 again, fixing the rotation angle of the threaded frame 12 to prevent the threaded frame 12 from rotating. Both ends of the slide groove 13 are fixed with a cover 14 by bolts. The cover 14 limits the connecting frame 4. A rubber pad 15 is bonded to one side of the clamping frame 6. When the clamping frame 6 clamps and fixes the cable body 1, the rubber pad 15 can reduce the force exerted by the clamping frame 6 on the cable body 1, and can also increase the friction between the clamping frame 6 and the cable body 1, thereby improving the safety and stability of clamping and fixing the cable body 1. The cable body 1 includes a cable core 21, an insulating layer 24 is sleeved on the outer side of the cable core 21, a fireproof layer 22 is sleeved on the outer side of the insulating layer 24, and the insulating layer 24 is located between the cable core 21 and the fireproof layer 22, a wear-resistant layer 23 is sleeved on the outer side of the fireproof layer 22, and the fireproof layer 22 is located between the insulating layer 24 and the wear-resistant layer 23. By providing the cable core 21 with a fireproof layer 22 and a wear-resistant layer 23, its fireproof and wear-resistant effects can be effectively increased, thereby greatly increasing the service life of the cable. Guide rods 8 are fixed to both sides of the connecting frame 2 by bolts, and the guide rods 8 pass through the connecting frame 24. The guide rods 8 play a guiding role when the connecting frame 24 moves.

[0026] Working principle: when the cables need to be connected, first plug the two cable bodies 1, and then rotate the two-way threaded rod 16. The two-way threaded rod 16 drives the clamping frame 6 to move toward each other, so that the clamping frame 6 clamps and fixes the cable body 1. When the clamping frame 6 has completed clamping and fixing the cable body 1, stop rotating the two-way threaded rod 16, and then pull the guide plate 3. During the movement of the guide plate 3, the guide column 7 will drive the connecting frame 2 4 along the slide groove 2 13 to move toward each other under the action of the guide groove 10. The connecting frame 2 4 drives the connecting frame 3 5 to move toward each other, and the connecting frame 3 5 drives the clamping frame 6 to move toward each other, so that the two cable bodies 1 fit more closely, avoiding the connection between the two cables from separating, and improving the stability of the cable connection. During the movement of the guide plate 3, the slide groove 1 9 will avoid the fixed plate 11. When the guide plate 3 moves to When the screw frame 12 is in the appropriate position, the clamping frame 18 is pressed to move the clamping frame 18 into the sliding tube 19 and squeeze the spring 17, and then the threaded frame 12 is rotated, and the threaded frame 12 will move into the threaded hole. At the same time, the threaded frame 12 drives the fixing plate 11 to move downward, and the fixing plate 11 will squeeze the guide plate 3. When the threaded frame 12 rotates to the bottom of the threaded hole, the guide plate 3 is clamped and fixed under the cooperation of the fixing plate 11 and the connecting frame 2, so that the guide plate 3 cannot move. When the threaded frame 12 rotates, the connecting rod 20 will be driven to rotate. When the threaded frame 12 rotates to the bottom of the threaded hole, the connecting rod 20 is still in the previous position. At this time, the clamping frame 18 is released, and the clamping frame 18 is reset under the action of the spring 17, so that the clamping frame 18 is clamped with the connecting rod 20 again, fixing the rotation angle of the threaded frame 12 to prevent the threaded frame 12 from rotating.

[0027] Finally, it should be noted that: for those skilled in the art, it is still possible to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
