[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] Please see Figure 1-4 This utility model provides: a protective wire and cable, including a wire and cable body 1 and a protective sleeve assembly 2 disposed on the surface of the wire and cable body 1; the protective sleeve assembly 2 includes a lower sheath 3 and an upper sheath 11, the top of the lower sheath 3 is provided with a positioning rod 5 that cooperates with the upper sheath 11, and the surfaces of the lower sheath 3 and the upper sheath 11 are provided with fixing clamps 19 for reinforcement; the two ends of the lower sheath 3 and the upper sheath 11 are respectively connected to a lower arc-shaped assembly plate 6 and an upper arc-shaped assembly plate 12, the lower arc-shaped assembly plate 6 is connected to the upper arc-shaped assembly plate 12 through a positioning component; the lower sheath 3 and the upper sheath 11 are both provided with an assembly groove 17, and the assembly groove 17 is provided with a shaping strip 18 to help stabilize the structure of the protective sleeve assembly 2.

[0019] It is worth noting that, through the coordinated arrangement of the main body 1 of the cable, the lower sheath 3, the positioning rod 5, the upper sheath 11, the shaping strip 18, the fixing clamp 19 and the positioning components, the corner bending part can be effectively protected when the cable is bent, reducing the direct contact between the cable bending part and the external environment and the external protection effect, reducing the occurrence of weathering and corrosion problems, and effectively preventing the cable bending part from being damaged.

[0020] Specifically, the positioning components include: mounting plates 7 connected to both sides of the lower arc-shaped assembly plate 6, and fixing plates 13 connected to both sides of the upper arc-shaped assembly plate 12; wherein, the bottom of the fixing plate 13 is connected to a limit guide rod 14, and a locking rod 8 is movably mounted on the surface of the mounting plate 7.

[0021] Furthermore, the lower arc-shaped assembly plate 6 is a structure that cooperates with the upper arc-shaped assembly plate 12 to realize the assembly and protection of the protective sleeve 2. The fixing plate 13 is connected to the mounting plate 7 through the limiting guide rod 14. The locking rod 8 is a locking structure that connects the mounting plate 7 and the fixing plate 13.

[0022] The mounting plate 7 has a positioning guide groove on its surface that mates with the limiting guide rod 14. The top end of the locking rod 8 is threaded to the fixing plate 13, and the bottom end of the locking rod 8 is connected to the anti-loosening plate 9. An anti-loosening spring 10 is fitted onto the surface of the locking rod 8, and one end of the anti-loosening spring 10 is connected to the surface of the anti-loosening plate 9. The anti-loosening plate 9 limits the anti-loosening spring 10, further enhancing its restraining effect and preventing accidental detachment or loss when not fully tightened, thus facilitating installation and subsequent maintenance.

[0023] In addition, a positioning groove 15 is connected to the bottom of the upper sheath 11, and a limiting strip 16 is connected to one side of the positioning groove 15. The end of the positioning rod 5 is movably inserted into the inner wall of the positioning groove 15, and a limiting groove 4 that cooperates with the limiting strip 16 is provided on one side of the positioning rod 5. The limiting strip 16 is a positioning structure that cooperates with the limiting groove 4 to improve the assembly efficiency of the lower sheath 3 and the upper sheath 11, and the positioning groove 15 is used to cooperate with the positioning rod 5 for assembly, further improving the stability of the assembly.

[0024] The shaping strip 18 inside the assembly slot 17 can fix and constrain the bending angle of the upper and lower sheaths, preventing the sheaths from bending excessively, wrinkling or collapsing locally when bending, ensuring that the cable is always within the safe bending range allowed by the design, and locking the preset bending angle and shape of the protective sleeve for a long time, ensuring the durability and consistency of the protective performance.

[0025] In use, the protective sleeve group 2 is fitted onto the surface of the wire and cable body 1 through the lower sheath 3 and the upper sheath 11. The positioning rod 5 at the top of the lower sheath 3 and the positioning groove 15 at the bottom of the upper sheath, as well as the limiting strip 16 and the limiting groove 4, effectively prevent misalignment during installation, improve installation speed and accuracy, and ensure that the initial positioning of the upper and lower sheaths is accurate when they are closed. To prevent relative slippage or misalignment, the overall integrity of the sleeve is enhanced. The cooperation of the positioning guide groove and the limiting guide rod ensures quick and accurate alignment of the lower and upper arc-shaped assembly plates during connection. The threaded locking rod, passing through the mounting plate and screwed into the fixing plate, provides mechanical locking force, tightly and firmly fixing the upper and lower arc-shaped assembly plates together, thus ensuring extremely high tensile strength and shear resistance at the connection point. Simultaneously, the anti-loosening spring on the locking rod continuously provides clamping force to counteract potential loosening of the threads due to vibration, temperature changes, or other factors. Finally, the clamp placed on the sleeve surface provides circumferential restraint, enhancing the protective sleeve's resistance to radial compression such as soil pressure and mechanical compression, as well as its overall impact toughness, effectively dispersing external impact loads.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
