Description

Technical Field

[0001] The invention belongs to the technical field of cable construction equipment, and in particular relates to an anti-theft device for a cable structure. Background Art

[0002] Cable trays are key devices used to support, protect, and manage cables during construction. They can be categorized by structure into various types, including trough, tray, ladder, and grid types, and consist of brackets, supports, and installation accessories. They are made of five materials: steel, aluminum alloy, stainless steel, fiberglass, and flame-retardant materials. They offer advantages such as lightweight structure, reliable strength, cost-effectiveness, and convenient installation. They also support flexible cable laying and subsequent maintenance, and are widely used in electronics, machinery, metallurgy, electricity, and other fields, as well as in high-rise building power supply systems. However, the design of traditional cable trays focuses on the physical protection of cables and wiring efficiency, with significant inadequacies in consideration of safety and protection functions.

[0003] Despite the widespread popularity of cable trays in engineering applications, their weak anti-theft performance is becoming increasingly prominent. For example, the hinged covers of traditional cable trays (such as trough-type) are easily damaged by hydraulic tools, and the fixing bolts have low shear strength, allowing thieves to dismantle the cable tray and steal the cables in a short period of time. There are no anti-theft locks between the cover and the trough, and the bolts have no anti-disassembly design, making cables vulnerable to theft. Furthermore, traditional cable trays are large in size and take up a lot of space, making them difficult to hoist and inconvenient to use in confined spaces, resulting in poor flexibility.

[0048] The following is attached with the instruction manual Figure 1 -Attached Figure 12 The structure of the cable structure anti-theft device of the present invention is described.

[0049] Example 1:

[0050] like Figures 1 to 12As shown, a cable structure anti-theft device is used as an alternative to cable bridges to provide anti-theft protection for cables 1 when in use. Its structure includes a cable protection mechanism 2 and a positioning mechanism 3. The cable protection mechanism 2 is directly sleeved on the outside of the cable 1 and rigidly connected to the cable 1 to form a fully enclosed protective structure to protect the cable 1 and prevent the cable from being cut and stolen; the positioning mechanism 3 is fixedly installed on the surface of the building structure and used in conjunction with the cable protection mechanism 2 to achieve spatial positioning and line summary of the cable 1, and can also enhance the overall anti-destruction ability through mechanical interlocking, thereby replacing the support and protection functions of traditional bridges. The cable protection mechanism 2 is composed of a plurality of movable sleeves 21 and segments 22: the sleeve 21 is a high-strength sleeve structure, which is spliced ​​and connected to the segment 22 through a connecting sleeve 23 to form a flexible cable protection mechanism 2 that can achieve high strength and anti-damage and anti-theft; the segment 22 is provided with a clamping and positioning component inside, which forms an interference fit with the outer sheath of the cable 1 to ensure electrical insulation performance while achieving anti-theft fixation.

[0051] In a preferred embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the segment sleeve 21 is a high-strength steel sleeve structure made by an integrated molding process, and the openings at both ends extend coaxially to form an anti-slip ring 211, and an axially extending movable cavity 212 is provided inside the segment sleeve 21. The diameter of the movable cavity 212 is slightly larger than the outer diameter of the connecting sleeve 23, and the outer diameter of the connecting sleeve 23 is larger than the inner diameter of the anti-slip ring 211. During assembly, the connecting sleeve 23 is completely constrained in the movable cavity 212 by the limiting effect of the anti-slip ring 211, and its axial displacement range is limited to between the anti-slip ring 211 and the end face of the segment 22, forming a mechanical anti-slip structure. A thread is also provided in the connecting sleeve 23 to connect with the external thread at the end of the segment 22 to form a self-locking connection.

[0052] In the above description, the anti-theft mechanism of this design is embodied in dual physical protection: first, the anti-disengagement ring 211 can prevent the axial disengagement of the connecting sleeve 23 through the annular flange structure; second, the connecting sleeve 23 is completely built into the movable cavity 212 of the segment sleeve 21, with no exposed threads or operating windows on the outside. Illegal disassembly requires destroying the segment sleeve 21 body first, which effectively increases the difficulty of theft. This structure makes it impossible for potential vandals to pull out the connecting sleeve 23 from the end, nor can it be disassembled by twisting with conventional tools. Combined with the elastic clamping component inside the segment 22, it can form a comprehensive anti-theft system that integrates tensile resistance, anti-rotation, and concealed connection, significantly improving the physical protection level of the cable line.

[0053] In a preferred embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown, the connecting sleeve 23 adopts a split assembly structure, consisting of two symmetrical arcuate connecting petals 231. Each connecting petal 231 has a mortise and tenon-type snap-fit ​​strip 232 and a snap-fit ​​groove 233 machined at each end. The snap-fit ​​strip 232 has a spherical raised cross-section, forming a precise fit with the spherical snap-fit ​​groove 233 of the adjacent connecting petal 231. This design allows the connecting sleeve 23 to be radially assembled within the active cavity 212 of the joint sleeve 21, providing greater flexibility and a smaller footprint after assembly, effectively avoiding the installation space requirements of traditional integral connecting sleeves.

[0054] In the above description, during on-site assembly, the two connecting petals 231 are manually aligned in the movable cavity 212, and the snap-fit ​​strip 232 is slid along the snap-fit ​​groove 233 to a position to form an annular closed structure. At this time, a gap is maintained between the outer wall of the connecting sleeve 23 and the movable cavity 212, which not only ensures the flexibility of horizontal rotation, but also ensures that the connecting sleeve 23 can be tilted relative to the connecting sleeve 23, and can also prevent the connecting sleeve 23 from being dislodged as a whole through the axial limitation of the anti-disengagement ring 211. Finally, the thread on the inner side of the connecting sleeve 23 engages with the thread at the end of the segment 22 to form a thread pair, which has a self-locking angle and an anti-loosening coating, and can form a mechanical connection node with both anti-theft function and anti-vibration performance after installation.

[0055] In a preferred embodiment, Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the clamping and positioning assembly is installed in the inner cavity of the segment 22 in a symmetrical layout, and is used to clamp the outside of the cable 1 to fix the position of the device on the cable 1, including a positioning plate 24 and an adjusting rod 25. The positioning plate 24 is an arc-shaped plate structure coaxial with the segment 22, and the inner arc surface of the positioning plate 24 is processed with anti-slip grooves to form surface contact with the outer sheath of the cable 1, which can ensure the clamping stability and avoid damage to the cable; the adjusting rod 25 is a double-headed trapezoidal thread screw, and both ends are supported in the mounting groove 221 on the side wall of the segment 22 by angular contact ball bearings, and an adjusting member 26 is threadedly connected to the threaded section of the adjusting rod 25. By rotating the adjusting rod 25, the two adjusting members 26 can be driven to move axially toward or away from each other; the adjusting member 26 is slidably connected to the positioning plate 24, and is used to convert the rotational motion into radial motion of the positioning plate 24 when the adjusting member 26 moves, thereby realizing a centering clamping action.

[0056] Specifically, such as Figure 5 、 Figure 6 and Figure 7As shown, the back side of the positioning plate 24 is precisely machined to form a dovetail-shaped connecting block 241. A fitting groove 242 is provided on the side of the connecting block 241 adjacent to the adjusting member 26. A hard chrome layer is plated on the surface of the connecting block 241 to enhance its strength. The groove 242 is capable of slidingly connecting with the engaging block 261 at the lower end of the adjusting member 26, forming a wear-resistant sliding pair. Therefore, when the adjusting rod 25 drives the adjusting member 26 to axially displace, the engaging block 261 generates a normal force component along the inclined wedge surface of the groove 242. This force component is converted into a radial clamping force of the positioning plates 24 through mechanical decomposition, driving the two positioning plates 24 to move toward or away from each other. A clearance notch 243 is also provided on the inner side of the positioning plate 24 to facilitate the passage of the cable 1 during use.

[0057] Specifically, such as Figure 5 、 Figure 6 and Figure 7 As shown, in order to facilitate the adjustment of the relative distance between the two positioning plates 24, the sliding groove 242 is opened on the wedge-shaped inclined surface of the slider 241. Therefore, when the locking block 261 slides along the sliding groove 242, the pressure of the wedge surface can drive the two positioning plates 24 to move toward or away from each other.

[0058] The construction and use principles of the cable anti-theft device described in this embodiment include:

[0059] This cable anti-theft device can achieve the anti-theft function through multi-level mechanical interlocking and mechanical coupling design. When the segment 22 is assembled with the segment sleeve 21 through the connecting sleeve 23, the anti-slip ring 211 and the annular groove of the connecting sleeve 23 form the first physical barrier, so that there is no exposed thread or operation window on the outside. Illegal disassembly requires destroying the segment sleeve 21 body first, effectively preventing the occurrence of theft. At the same time, the split arc-shaped petal 231 of the connecting sleeve 23 is spliced ​​with the engaging groove 233 through the mortise and tenon type engaging strip 232, and its thread forms a self-locking connection with the thread pair of the segment 22, which can effectively prevent the thread from loosening. By rotating the adjusting rod 25, the two adjusting parts 26 are driven to axially displace, and the rotary motion is converted into the radial clamping force of the positioning plate 24 through the wedge action of the wedge slider 261 and the back side slide groove 242 of the positioning plate 24 to clamp and position the cable 1, thereby avoiding the cable protection mechanism 2 from sliding on the surface of the cable 1 and affecting the protection effect of the cable 1. By setting the above structure, the electrical insulation performance of the cable 1 can be ensured while achieving anti-theft fixation during use, and the entire device is easy to use during construction and is convenient to install and fix on the outside of the cable 1.

[0060] Example 2:

[0061] Different from the above embodiment 1, Figure 1 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, the positioning mechanism 3 is used to arrange the cable protection mechanism 2 and the cable 1, facilitating the installation of the cable 1 on the structure during construction, while ensuring flexibility during the cable installation process. It includes a mounting frame 31, a connecting frame 32, and several cable positioning components. The mounting frame 31 is a rectangular frame made of high-strength aluminum alloy profiles, and a T-shaped mounting groove 311 is opened axially on its top surface. The mounting groove 311 is interconnected with an adjustment groove 312 that is set on the side wall of one side of the mounting frame 31 to form interconnected adjustment grooves. The connecting frame 32 is set on the lower side of the mounting frame 31 and plays a role in installation and connection, and is used to install the mounting frame 31 on the structure. The cable positioning assembly is slidably embedded in the installation groove 311, and the bottom of the base is provided with a trapezoidal base 35 that cooperates with the sliding adjustment groove 312 to ensure torsional rigidity during horizontal adjustment. At the same time, the cable positioning assembly is used to clamp on the outside of the segment 22 when in use to achieve the installation and fixation of the cable protection mechanism 2. A knurled surface is also provided on the inner side of the clamp 33 of the cable positioning assembly to enhance the friction with the segment 22.

[0062] In a preferred embodiment, Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the cable positioning assembly includes an arc-shaped clamp 33, a connecting seat 34, and a base 35. The clamp 33 is movably mounted in an arc-shaped groove 342 at the upper end of the connecting seat 34. An inclined external thread 331 is machined on the outer surface of the clamp 33 to engage with a worm gear 36. The clamp 33 is driven to move in the arc-shaped groove 342 by rotating the worm gear 36 to adjust the extension length of the clamp 33, so that it cooperates with the slot 341 on the upper end surface of the connecting seat 34 to fix the segment 22 engaged in the slot 341. The connecting seat 34 is rotatably mounted on the upper end of the base 35 to fix the clamp 33 and the worm gear 36. The base 35 is slidably installed in the installation groove 311, and a positioning screw 351 is installed on one side of the base 35. The positioning screw 351 is set through the sliding adjustment groove 312 and is threadedly connected to the threaded sleeve 352. It is used to fix the position of the base 35 in the installation groove 311 by tightening the threaded sleeve 352 during use, so as to adjust the position of the base 35 in the installation groove 311.

[0063] In the above description, the arc-shaped clamp 33 is provided to facilitate the fixing of the segment 22 in conjunction with the slot 341 during use. The base 35 is provided to facilitate sliding in the mounting slot 311 to adjust the position of the base 35 according to specific working conditions.

[0064] Specifically, such as Figure 10 and Figure 11As shown, a threaded groove 353 is provided in the middle of the base 35, and the threaded groove 353 is threadedly connected to the threaded sleeve 343 provided at the bottom of the connecting seat 34, so as to rotate the connecting seat 34 according to needs during use to adjust the installation height of the connecting seat 34 so that its installation height meets the installation requirements under different working conditions.

[0065] Specifically, such as Figure 10 and Figure 11 As shown, the worm gear 36 is rotatably mounted on the connecting seat 34 via a rotating shaft 37, so that the extension position of the clamp 33 can be adjusted by rotating the rotating shaft 37 during use, so as to fix cables 1 of different specifications and diameters.

[0066] Specifically, such as Figure 10 and Figure 12 As shown, the connecting frame 32 is detachably mounted on the lower side of the mounting frame 31 via connecting bolts.

[0067] The construction and use principles of the cable anti-theft device described in this embodiment include:

[0068] First, the mounting bracket 31 is positioned and secured. The operator attaches the mounting bracket 31 to the surface of the structure through the bend of the connecting bracket 32, using the oblong hole adjustment structure to adapt to different mounting surfaces (such as angle steel or concrete wall), and achieves a rigid connection through the bolt assembly. At this point, the base 35 of the cable positioning assembly 33 is in its initial position. Based on the layout of the cable protection mechanism 2, the operator slides the base 35 along the mounting slot 311 to the target area. The positioning screw 351, which passes through the sliding adjustment slot 312, is pre-tightened by the threaded sleeve 352 to initially secure the base 35. This stage focuses on using the sliding adjustment function of the base 35 to quickly determine the macroscopic position of each cable positioning assembly 33, laying the foundation for subsequent precise adjustment. The operator then rotates the worm gear 36, driving the arc clamp 33 axially along the arc slot 342 of the connecting bracket 34 through the worm drive, clamping the segment 22 in place using the external thread 331 and the worm gear 36. Then, the threaded sleeve 352 is completely tightened, and the base 35 is fixed to the outside of the installation groove 311 by clamping the positioning screw 351, forming a cable installation frame structure, which is convenient for anti-theft installation of cables during construction.

[0069] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention.
