DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] Embodiment 1: refer to Figures 1-6 A cable is mainly composed of two waterproof cable tubes 1, and the two waterproof cable tubes 1 are internally fixedly installed with flame-retardant layers 2, and the flame-retardant layers 2 are internally fixedly installed with multiple wires 3 at equal intervals. In addition to these basic structures, the cable further comprises connecting mechanisms and two supporting mechanisms.

[0029] The connecting mechanism is designed to connect two waterproof cable pipes 1. Specifically, the connecting mechanism comprises a first mounting ring 4 and a second mounting ring 6 fixedly clamped on the ends of the two waterproof cable pipes 1 close to each other. The first mounting ring 4 is fixedly installed with an outer pipe 5, and the second mounting ring 6 is fixedly installed with an inner pipe 7. One end of the inner pipe 7 can extend into the outer pipe 5 and tightly contact the inner wall of the outer pipe 5. Inside the outer pipe 5, an electrical connection assembly is installed, and one end of the wire 3 is connected to the electrical connection assembly. In actual installation, the outer pipe 5 and the inner pipe 7 are first installed on the ends of the two waterproof cable pipes 1, and then the wire 3 is inserted into the electrical connection assembly. Then, the inner pipe 7 is inserted into the outer pipe 5, and the wire 3 is closed due to the insertion fit of the outer pipe 5 and the inner pipe 7, thereby achieving waterproof protection during cable connection.

[0030] To ensure that the inner pipe 7 and the outer pipe 5 can be stably installed on the waterproof cable pipe 1, a plurality of hoops 13 are fixedly installed at equal intervals on the ends of the inner pipe 7 and the outer pipe 5 away from each other. These hoops 13 can be clamped with the same waterproof cable pipe 1, and a limiting ring 14 is tightly sleeved on the plurality of hoops 13. During installation, the plurality of hoops 13 are used to clamp the waterproof cable pipe 1, and then the limiting ring 14 is sleeved on the plurality of hoops 13 to limit the hoops 13. In this way, the hoops 13 can tightly clamp the waterproof cable pipe 1, thereby ensuring that the inner pipe 7 or the outer pipe 5 can be stably installed.

[0031] To further enhance the connection stability of the inner pipe 7 and the outer pipe 5, a fixed ring 11 is fixedly sleeved on the outer pipe 5, and a plurality of buckles 12 are fixedly installed at equal intervals on one side of the fixed ring 11. Meanwhile, a beveled clasp ring 8 is fixedly sleeved on the inner pipe 7, and the buckles 12 can be clamped with the beveled clasp ring 8. After the inner pipe 7 is inserted into the outer pipe 5, the buckles 12 will move along the slope of the beveled clasp ring 8 until they are clamped with the beveled clasp ring 8, thereby achieving stable clamping connection of the inner pipe 7 and the outer pipe 5.

[0032] The specific structure of the electrical connection assembly comprises an insulating support frame 9 fixedly installed in the outer pipe 5, and a plurality of conductive pipes 10 fixedly installed at equal intervals in the insulating support frame 9. One end of the wire 3 can extend into the corresponding conductive pipe 10 and electrically connect with the conductive pipe 10. In this way, after the wires 3 on both sides are inserted into the same conductive pipe 10, the conductive pipe 10 can be used to transmit current, thereby facilitating the connection of the wires 3 on both sides.

[0033] The support mechanism is designed to support and position the cable. Specifically, the support mechanism comprises a positioning frame 15 sleeved on the waterproof cable tube 1, and a mounting frame 16 fixedly installed at the bottom of the positioning frame 15, and two fixing holes symmetrically formed on the mounting frame 16. Inside the positioning frame 15, a clamping assembly is installed, and the top of the clamping assembly penetrates through the inner wall of the top of the positioning frame 15 and extends above the positioning frame 15 to clamp the waterproof cable tube 1. During installation, the positioning frame 15 is sleeved on the waterproof cable tube 1, and then the clamping assembly is driven to clamp and position the waterproof cable tube 1 in cooperation with the positioning frame 15. Then, two bolts are respectively passed through the corresponding fixing holes and connected with the wall or a cable supporting carrier, so that the cable is stably supported.

[0034] The specific structure of the clamping assembly comprises a clamping plate 17 slidably connected in the positioning frame 15, which is used to clamp the waterproof cable tube 1. The top of the clamping plate 17 is connected with a threaded member, and the top end of the threaded member penetrates through the inner wall of the top of the positioning frame 15 and extends above the positioning frame 15. By driving the threaded member, the clamping plate 17 can be moved to clamp and position the waterproof cable tube 1 by the clamping plate 17. In this way, when the cable is supported, the cable can be stably supported.

[0035] The present application can be used in the field of cable technology, and can also be used in other fields applicable to the present application.

[0036] Embodiment 2: Reference Figure 6 On the basis of Embodiment 1, a new type of water-blocking fireproof cable is improved: applied to the field of cable technology, the specific structure of the threaded member comprises a screw rod 18 rotatably connected to the clamping plate 17, and a nut 19 fixedly installed on the top inner wall of the positioning frame 15. The top end of the screw rod 18 penetrates through the nut 19 and the top inner wall of the positioning frame 15 and extends above the positioning frame 15, and is threadedly connected with the nut 19. By rotating the screw rod 18, the clamping plate 17 can be moved by the threaded transmission action of the screw rod 18 and the nut 19, so that the clamping plate 17 can clamp and position the waterproof cable tube 1. Moreover, since the screw rod 18 and the nut 19 have the self-locking property, the clamping plate 17 can be limited, so as to ensure that the clamping plate 17 can stably clamp the waterproof cable tube 1.

[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
