Description

Technical Field

[0001] This application relates to the field of armored optical cables, and in particular to a tool for cutting the armor of armored optical cables. Background Technology

[0002] Traditional optical cable armor removal processes primarily rely on handheld cutting tools (such as diagonal pliers and cable shears) combined with manual stripping operations. This method has significant technical drawbacks: First, operators must apply immense shearing force to penetrate the metal armor layer, resulting in high labor intensity and a risk of slippage and injury to the operator. Second, manual operation makes it difficult to precisely control the cutting depth, easily causing mechanical damage to the internal loose tubes or fiber units. Third, existing tools lack adaptive adjustment mechanisms, requiring frequent tool changes when dealing with different armor structures (such as double-layer reverse-stranded armor and longitudinally welded armor), severely impacting construction efficiency. Summary of the Invention

[0003] To facilitate workers in unscrewing the protective layer of armored optical cables and to make them easy to carry, this application proposes an auxiliary tool for cutting the armor of armored optical cables.

[0004] The armor-cutting tool for auxiliary armored optical cables provided in this application adopts the following technical solution: A tool for cutting armored optical cables, comprising: a first half and a second half, wherein the second half abuts against and is pivotally connected to the sidewall of the first half.

[0005] The first half has a first notch, and the second half has a second notch that matches the first notch. The first notch and the second notch are opposite to each other. The armored optical cable passes through the first notch and the second notch. The armored optical cable is limited to both the first half and the second half, and is suitable for driving the second half to rotate around the pivot axis between the second half and the first half, so as to unscrew the protective layer of the armored optical cable.

[0006] The first half is provided with a first fixing unit, and the second half is provided with a second fixing unit. The first fixing unit is used to fix the armored optical cable passing through the first gap in the first gap, and the second fixing unit is used to fix the armored optical cable passing through the second gap in the second gap.

[0007] By adopting the above technical solution, the armored optical cable is fixed by the first fixing unit and the second fixing unit. The first half clamps the protective layer of the armored optical cable, and the second half drives the protective layer of the armored optical cable to rotate around the central axis of the armored optical cable, so as to unscrew the protective layer of the armored optical cable and expose the optical fiber of the armored optical cable.

[0008] Preferably, one side of the first half is provided with a first groove, and the side of the second half opposite to the side of the first half with the first groove is provided with a protrusion, and the protrusion can rotate within the first groove so that the second half can rotate about the axis of the first half.

[0009] By adopting the above technical solution, by setting the first groove and the protrusion, the second half can be stuck in the first half, and the protrusion can rotate in the first groove, so that the second half can rotate around the axis of the first half, which is conducive to unscrewing the protective layer of the armored optical cable. The staff only needs to press the second half against the first half, that is, align the protrusion with the first groove and lock it in the first groove, which is convenient for the staff to operate.

[0010] Preferably, the first fixing unit includes a first fixing hole and a first adjusting rod. The first fixing hole is located on the first half and communicates with the first notch. The first adjusting rod is connected in the first fixing hole and can be raised and lowered relative to the first fixing hole to press the armored optical cable into the first notch.

[0011] The second fixing unit includes a second fixing hole and a second adjusting rod. The second fixing hole is located on the second half and communicates with the second notch. The second adjusting rod is connected in the second fixing hole and can be raised and lowered relative to the second fixing hole to press the armored optical cable into the second notch.

[0012] By adopting the above technical solution, when the preset cutting position of the armored optical cable is opposite to both the first notch and the second notch, the first adjusting rod and the second adjusting rod are driven to move closer to the armored optical cable. The first adjusting rod and the second adjusting rod together press the armored optical cable into the first notch and the second notch, thereby preventing the second half from being unable to drive the protective layer of the armored optical cable to rotate around the central axis of the armored optical cable, thereby improving the reliability of the auxiliary armor cutting tool.

[0013] Preferably, the first adjusting rod is a screw, the first fixing hole is provided with an internal thread, and the first adjusting rod is threadedly connected to the first fixing hole. The second adjusting rod is a screw, the second fixing hole is provided with an internal thread, and the second adjusting rod is threadedly connected to the second fixing hole.

[0014] By adopting the above technical solution, the first adjusting rod and the first fixing hole are threadedly connected, and the second adjusting rod and the second fixing hole are threadedly connected, so as to prevent the first adjusting rod and / or the second adjusting rod from becoming loose.

[0015] Preferably, the first half includes a first fixed block and a first rotating block. One end of the first fixed block is hinged to one end of the first rotating block. The first fixed block has a first through groove near the end wall of the first rotating block, and the first rotating block has a second through groove near the end wall of the first fixed block. The first through groove and the second through groove form the first notch, which is suitable for driving the first rotating block to rotate around the rotation axis of the first rotating block to open or close the first notch.

[0016] The second half includes a second fixed block and a second rotating block. One end of the second fixed block is hinged to one end of the second rotating block. The second fixed block has a third through groove near the end wall of the second rotating block, and the second rotating block has a fourth through groove near the end wall of the second fixed block. The third through groove and the fourth through groove form the second notch, which is suitable for driving the second rotating block to rotate around the rotation axis of the second rotating block to open or close the second notch.

[0017] By adopting the above technical solution, the first rotating block is driven to rotate away from the first fixed block around the pivot axis between the first rotating block and the first fixed block to open the first gap, and the second rotating block is driven to rotate away from the second fixed block around the pivot axis between the second rotating block and the second fixed block to open the second gap, so that the armored optical cable can be placed in the first gap and the second gap.

[0018] Preferably, the projections of the first and third through slots on the vertical cross section are inverted triangles, and the projections of the second and fourth through slots on the vertical plane are equilateral triangles. The first and second through slots combine to form the first notch with a square structure, and the third and fourth through slots combine to form the second notch with a square structure.

[0019] By adopting the above technical solution, when the armored optical cable is placed in the first gap and the second gap, the outer peripheral wall of the armored optical cable is in a stop-fitting fit with the inner peripheral wall of the first gap and the inner peripheral wall of the second gap. The first half and the second half can better clamp the armored optical cable, so that the protective layer of the armored optical cable can be quickly unscrewed using the second half.

[0020] Preferably, a first locking unit is provided at the end of the first rotating block away from the rotation axis of the first rotating block, and a second locking unit is provided at the end of the second rotating block away from the rotation axis of the second rotating block. The first locking unit is used to lock the first rotating block onto the first fixed block, and the second locking unit is used to lock the second rotating block onto the second fixed block.

[0021] By adopting the above technical solution, the first rotating block is locked to the first fixed block by the first locking unit, and the second rotating block is locked to the second fixed block by the second locking unit. This prevents the first rotating block from rotating relative to the first fixed block and / or the second rotating block from rotating relative to the second fixed block when the protective layer of the armored optical cable is unscrewed in the second half. This also avoids the second half being unable to unscrew the protective layer of the armored optical cable.

[0022] Preferably, the first locking unit is a first locking block. The first rotating block has a second groove at one end away from the rotation axis of the first rotating block. The first locking block is hinged in the second groove. One end of the first locking block has a first barb. The first fixing block has a first fixing rod. The first locking block can rotate so that the first barb is engaged with the first fixing rod to lock the first rotating block onto the first fixing block.

[0023] The second locking unit is a second locking block. The second rotating block has a third groove on one end away from the rotation axis of the second rotating block. The second locking block is hinged in the third groove. One end of the second locking block has a second barb. The second fixing block has a second fixing rod. The second locking block can rotate so that the second barb is engaged with the second fixing rod to lock the second rotating block onto the second fixing block.

[0024] By adopting the above technical solution, the first locking block is driven to rotate close to the first fixed block around the pivot axis of the first locking block and the first rotating block, so that the first barb engages with the first fixed rod, thereby achieving the technical effect of fixing the first rotating block and the first fixed block through the first barb and the first fixed rod. Furthermore, the second locking block is driven to rotate close to the second fixed block around the pivot axis of the second locking block and the second rotating block, so that the second barb engages with the second fixed rod, thereby achieving the technical effect of fixing the second rotating block and the second fixed block through the second barb and the second fixed rod.

[0025] Preferably, a first spring is provided on the side wall of the first locking block near the second groove. The first spring is located between the bottom wall of the second groove and the first locking block, and the first spring is used to drive the first locking block to rotate closer to the first rotating block.

[0026] A second spring is provided on the side wall of the second locking block near the third groove. The second spring is located between the bottom wall of the third groove and the second locking block. The second spring is used to drive the second locking block to rotate closer to the second rotating block.

[0027] By adopting the above technical solution, the first spring drives the first locking block to rotate the first barb close to the first fixed rod, so that the first barb and the first fixed rod are tightly fitted together. This can prevent the first barb from separating from the first fixed rod when the protective layer of the armored optical cable is unscrewed with the auxiliary armor cutting tool, and can avoid the first half being unable to fix the armored optical cable.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. The armored optical cable is fixed by the first fixing unit and the second fixing unit. The first half clamps the protective layer of the armored optical cable, and the second half drives the protective layer of the armored optical cable to rotate around the central axis of the armored optical cable, so as to unscrew the protective layer of the armored optical cable and expose the optical fiber of the armored optical cable. 2. By locking the first rotating block to the first fixed block by the first locking unit and locking the second rotating block to the second fixed block by the second locking unit, it is possible to prevent the first rotating block from rotating relative to the first fixed block and / or the second rotating block from rotating relative to the second fixed block when the protective layer of the armored optical cable is unscrewed in the second half, thereby preventing the second half from being unable to unscrew the protective layer of the armored optical cable. 3. The first spring drives the first locking block to rotate the first barb close to the first fixed rod, so that the first barb and the first fixed rod are tightly engaged. This prevents the first barb from separating from the first fixed rod when the protective layer of the armored optical cable is unscrewed using an auxiliary armor-cutting tool, thus avoiding the first half being unable to fix the armored optical cable.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses an auxiliary armor-cutting tool 100 for armored optical cables. The armor-cutting tool 100 is used to unscrew the protective layer of the armored optical cable. The armored optical cable includes an optical fiber and a protective layer, and the protective layer is spirally wound around the outer wall of the optical fiber.

[0033] Reference Figure 1 and Figure 2 According to an embodiment of this application, the armor-cutting tool 100 for the auxiliary armored optical cable includes: a first half 1 and a second half 2, wherein the second half 2 abuts against and is pivotally connected to the side wall of the first half 1.

[0034] The first half 1 has a first notch 11, and the second half 2 has a second notch 21 that matches the first notch 11. The first notch 11 and the second notch 21 are opposite to each other. The armored optical cable passes through the first notch 11 and the second notch 21. The armored optical cable is in a limiting fit with both the first half 1 and the second half 2, which is suitable for driving the second half 2 to rotate around the pivot axis between the second half 2 and the first half 1, so as to unscrew the protective layer of the armored optical cable.

[0035] The first half 1 is provided with a first fixing unit 12, and the second half 2 is provided with a second fixing unit 22. The first fixing unit 12 is used to fix the armored optical cable passing through the first gap 11 inside the first gap 11, and the second fixing unit 22 is used to fix the armored optical cable passing through the second gap 21 inside the second gap 21.

[0036] In actual operation, the armored optical cable passes through the first notch 11 and the second notch 21. When the preset cutting position of the armored optical cable is opposite to the first notch 11, the armored optical cable is fixed by the first fixing unit 12 and the second fixing unit 22. The first half 1 clamps the protective layer of the armored optical cable, and the second half 2 drives the protective layer of the armored optical cable to rotate around the central axis of the armored optical cable, so as to unscrew the protective layer of the armored optical cable and expose the optical fiber of the armored optical cable.

[0037] It should be noted that the rotation direction of the second half 2 is opposite to the winding direction of the protective layer of the armored optical cable, so that the protective layer can be unscrewed in the opposite direction.

[0038] Furthermore, when the armored optical cable is not jointly fixed by the first fixing unit 12 and the second fixing unit 22, the operator can adjust the relative position of the armored optical cable with the first notch 11 and the second notch 21, thereby adjusting the cutting position of the armored optical cable.

[0039] Reference Figure 1 and Figure 2 In some embodiments of this application, a first groove 13 is provided on one side of the first half 1, and a protrusion 23 is provided on the side of the second half 2 opposite to the side of the first half 1 where the first groove 13 is provided. The protrusion 23 extends into the first groove 13 and can rotate within the first groove 13 so that the second half 2 can rotate around the axis of the first half 1.

[0040] When cutting the armored optical cable using the first half 1 and the second half 2, the protrusion 23 is inserted into the first groove 13 to assemble the first half 1 and the second half 2 into an armor-cutting tool 100. When unscrewing the protective layer of the armored optical cable using the second half 2, the second half 2 rotates around the central axis of the first notch 11. The central axis of the first notch 11 is coaxial with the central axis of the armored optical cable so that the second half 2 can smoothly unscrew the protective layer of the armored optical cable.

[0041] By setting the first groove 13 and the protrusion 23, the second half 2 can be locked inside the first half 1, and the protrusion 23 can rotate inside the first groove 13, so that the second half 2 can rotate around the axis of the first half 1, which is convenient for unscrewing the protective layer of the armored optical cable. The operator only needs to press the second half 2 against the first half 1, that is, align the protrusion 23 with the first groove 13 and lock it inside the first groove 13, which is convenient for the operator to operate.

[0042] Reference Figure 1 and Figure 2 In some embodiments of this application, the first fixing unit 12 includes a first fixing hole 121 and a first adjusting rod 122. The first fixing hole 121 is disposed on the first half 1 and communicates with the first notch 11. The first adjusting rod 122 is connected in the first fixing hole 121. The first adjusting rod 122 can be raised and lowered relative to the first fixing hole 121 to press the armored optical cable into the first notch 11.

[0043] The second fixing unit 22 includes a second fixing hole 221 and a second adjusting rod 222. The second fixing hole 221 is located on the second half 2 and communicates with the second notch 21. The second adjusting rod 222 is connected in the second fixing hole 221. The second adjusting rod 222 can be raised and lowered relative to the second fixing hole 221 to press the armored optical cable into the second notch 21.

[0044] When the armored optical cable passes through the first notch 11 and the second notch 21, and the preset cutting position of the armored optical cable is opposite to both the first notch 11 and the second notch 21, that is, when the protective layer of the armored optical cable is opposite to both the first fixing hole 121 and the second fixing hole 221, the first adjusting rod 122 and the second adjusting rod 222 are driven to move closer to the armored optical cable so that both the first adjusting rod 122 and the second adjusting rod 222 are in a stop-fitting engagement with the outer peripheral wall of the protective layer of the armored optical cable. The first adjusting rod 122 and the second adjusting rod 222 together press the armored optical cable tightly within the first notch 11 and the second notch 21, thereby preventing the second half 2 from being unable to drive the protective layer of the armored optical cable to rotate around the central axis of the armored optical cable, thereby improving the reliability of the armor cutting tool 100.

[0045] In some embodiments of this application, the first adjusting rod 122 is a screw, the first fixing hole 121 is provided with an internal thread, and the first adjusting rod 122 is threadedly connected to the first fixing hole 121. The second adjusting rod 222 is a screw, the second fixing hole 221 is provided with an internal thread, and the second adjusting rod 222 is threadedly connected to the second fixing hole 221.

[0046] When the armored optical cable is placed in the first notch 11 and the second notch 21, the first adjusting rod 122 and the second adjusting rod 222 are turned so that both the first adjusting rod 122 and the second adjusting rod 222 move closer to the armored optical cable and abut against the armored optical cable, thereby achieving the technical effect of fixing the armored optical cable using the first adjusting rod 122 and the second adjusting rod 222.

[0047] The threaded connection between the first adjusting rod 122 and the first fixing hole 121, and the threaded connection between the second adjusting rod 222 and the second fixing hole 221, can prevent the first adjusting rod 122 and / or the second adjusting rod 222 from becoming loose.

[0048] Reference Figures 2-4 In some embodiments of this application, the first half 1 includes a first fixed block 14 and a first rotating block 15. One end of the first fixed block 14 is hinged to one end of the first rotating block 15, and the other end of the first fixed block 14 is movably disposed with the other end of the first rotating block 15. The first fixed block 14 is provided with a first through groove 141 near the end wall of the first rotating block 15, and the first rotating block 15 is provided with a second through groove 151 near the end wall of the first fixed block 14. The first through groove 141 and the second through groove 151 are disposed opposite to each other, and the first through groove 141 and the second through groove 151 form a first notch 11, which is suitable for driving the first rotating block 15 to rotate around the rotation axis of the first rotating block 15 to open or close the first notch 11.

[0049] The second half 2 includes a second fixed block 24 and a second rotating block 25. One end of the second fixed block 24 is hinged to one end of the second rotating block 25, and the other end of the second fixed block 24 is movably disposed with the other end of the second rotating block 25. The end wall of the second fixed block 24 near the second rotating block 25 is provided with a third through groove 241, and the end wall of the second rotating block 25 near the second fixed block 24 is provided with a fourth through groove 251. The third through groove 241 and the fourth through groove 251 are disposed opposite to each other, and the third through groove 241 and the fourth through groove 251 form a second notch 21, which is suitable for driving the second rotating block 25 to rotate around the rotation axis of the second rotating block 25 to open or close the second notch 21.

[0050] When the armored optical cable is placed in the first notch 11 and the second notch 21, the first rotating block 15 is driven to rotate away from the first fixed block 14 around the pivot axis between the first rotating block 15 and the first fixed block 14 to open the first notch 11, and the second rotating block 25 is driven to rotate away from the second fixed block 24 around the pivot axis between the second rotating block 25 and the second fixed block to open the second notch 21. This allows the armored optical cable to be placed in the first notch 11 and the second notch 21, reducing the difficulty of placing the armored optical cable in the armor-cutting tool 100.

[0051] Then, the first rotating block 15 is driven to rotate about the pivot axis between the first rotating block 15 and the first fixed block 14 and approach the first fixed block 14 to close the first notch 11, and the second rotating block 25 is driven to rotate about the pivot axis between the second rotating block 25 and the second fixed block and approach the second fixed block 24 to close the second notch 21.

[0052] Reference Figure 3 and Figure 4 In some embodiments of this application, the projections of the first through groove 141 and the third through groove 241 on the vertical cross section are inverted triangles, and the projections of the second through groove 151 and the fourth through groove 251 on the vertical plane are equilateral triangles. The first through groove 141 and the second through groove 151 combine to form a first notch 11 with a square structure, and the third through groove 241 and the fourth through groove 251 combine to form a second notch 21 with a square structure.

[0053] It should be noted that the cross-sectional shape of the armored optical cable is circular.

[0054] The first notch 11, which is square in shape, is formed by the combination of the first through groove 141 and the second through groove 151, and the second notch 21, which is square in shape, is formed by the combination of the third through groove 241 and the fourth through groove 251. When the armored optical cable is placed in the first notch 11 and the second notch 21, the outer peripheral wall of the armored optical cable is in a stop-fitting fit with the inner peripheral wall of the first notch 11 and the inner peripheral wall of the second notch 21. The first half 1 and the second half 2 can better clamp the armored optical cable, so that the protective layer of the armored optical cable can be quickly unscrewed using the second half 2.

[0055] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, a first locking unit 152 is provided at one end of the first rotating block 15 away from the rotation axis of the first rotating block 15, and a second locking unit 252 is provided at one end of the second rotating block 25 away from the rotation axis of the second rotating block 25. The first locking unit 152 is used to lock the first rotating block 15 on the first fixed block 14, and the second locking unit 252 is used to lock the second rotating block 25 on the second fixed block 24.

[0056] When the armored optical cable is placed in the first notch 11 and the second notch 21, the first rotating block 15 is locked to the first fixed block 14 by the first locking unit 152, and the second rotating block 25 is locked to the second fixed block 24 by the second locking unit 252. This prevents the first rotating block 15 from rotating relative to the first fixed block 14 and / or the second rotating block 25 from rotating relative to the second fixed block 24 when the protective layer of the armored optical cable is unscrewed in the second half 2. This avoids the second half 2 from being unable to unscrew the protective layer of the armored optical cable, thereby improving the reliability of the armor-cutting tool 100.

[0057] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the first locking unit 152 is a first locking block 153. The first rotating block 15 is provided with a second groove 154 at one end away from the rotation axis of the first rotating block 15. The first locking block 153 is hinged in the second groove 154. One end of the first locking block 153 is provided with a first barb 155. The first fixing block 14 is provided with a first fixing rod 142. The first locking block 153 can rotate so that the first barb 155 is engaged with the first fixing rod 142, so as to lock the first rotating block 15 on the first fixing block 14.

[0058] The second locking unit 252 is the second locking block 253. The second rotating block 25 has a third groove 254 on one end away from the rotation axis of the second rotating block 25. The second locking block 253 is hinged in the third groove 254. One end of the second locking block 253 has a second barb 255. The second fixing block 24 has a second fixing rod 242. The first locking block 153 can rotate so that the first barb 155 is locked in the first fixing rod 142, so as to lock the first rotating block 15 on the first fixing block 14.

[0059] When the armored optical cable is placed in the first notch 11 and the second notch 21, and the first rotating block 15 closes the first notch 11 and the second rotating block 25 closes the second notch 21, the first locking block 153 is driven to rotate around the pivot axis of the first locking block 153 and the first rotating block 15 towards the first fixed block 14, so that the first barb 155 engages with the first fixed rod 142. This achieves the technical effect of fixing the first rotating block 15 and the first fixed block 14 together through the first barb 155 and the first fixed rod 142. The second locking block 253 is driven to rotate around the pivot axis of the second locking block 253 and the second rotating block 25 close to the second fixed block 24, so that the second barb 255 engages with the second fixed rod 242. This achieves the technical effect of fixing the second rotating block 25 and the second fixed block 24 through the second barb 255 and the second fixed rod 242. This avoids the second rotating block 25 from opening the second notch 21 when the protective layer of the armored optical cable is unscrewed in the second half 2, thereby improving the working reliability of the armor cutting tool 100.

[0060] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, a first spring 156 is provided on the side wall of the first locking block 153 near the second groove 154. The first spring 156 is located between the bottom wall of the second groove 154 and the first locking block 153. The first spring 156 is used to drive the first locking block 153 to rotate near the first rotating block 15.

[0061] A second spring 256 is provided on the side wall of the second locking block 253 near the third groove 254. The second spring 256 is located between the bottom wall of the third groove 254 and the second locking block 253. The second spring 256 is used to drive the second locking block 253 to rotate near the second rotating block 25.

[0062] After the first barb 155 engages with the first fixing rod 142, the first spring 156 is compressed. The first spring 156 applies elastic force to the first locking block 153. The first spring 156 drives the first locking block 153 to rotate the first barb 155 close to the first fixing rod 142, so that the first barb 155 and the first fixing rod 142 are tightly fitted together. This prevents the first barb 155 from separating from the first fixing rod 142 when the armored optical cable is unscrewed with the armor cutting tool 100, thus avoiding the first half 1 from being unable to fix the armored optical cable.

[0063] After the second barb 255 engages with the second fixing rod 242, the second spring 256 is compressed. The second spring 256 applies elastic force to the second locking block 253. The second spring 256 drives the second locking block 253 to rotate the second barb 255 closer to the second fixing rod 242, so that the second barb 255 and the second fixing rod 242 are tightly fitted together. This prevents the second barb 255 from separating from the second fixing rod 242 when the armored optical cable is unscrewed with the armor cutting tool 100, thus preventing the second half 2 from being unable to unscrew the armored optical cable's protective layer.

[0064] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
