Description

Technical Field

[0001] This invention relates to the field of cable installation technology, specifically to an auxiliary structure for cable protection pipe sleeve connection. Background Technology

[0002] Power cables are an important carrier for transmitting and distributing electrical energy and have been widely used in the power industry. They can be found in power plants, transmission networks, distribution networks, and various factories. Using power cables to transmit and distribute electrical energy can improve the reliability of power supply. For protection and aesthetic reasons, cables are often laid underground and buried in soil. At the connection point between the cable end and the power equipment, the cable often needs to extend upwards from underground. Here, the cable is exposed and easily damaged. Therefore, in current cable construction, exposed cables are often protected by metal cable protection pipes. The bottom of the metal cable protection pipe extends into the soil and is used to connect the cable.

[0003] Currently, the installation of cable protection pipes requires welding to the distribution cabinet, and outdoor welding requires specialized welding equipment, making the installation of cable protection pipes very inconvenient and resulting in low installation efficiency for workers.

[0004] Meanwhile, after the cable protection pipe is installed, the end of the cable entering the distribution cabinet will come into contact with the inner wall of the protection pipe or interface and rub against it, damaging the cable. Moreover, when the cable is connected to the distribution cabinet, it may need to be split. The messy split wires are more likely to come into contact with the inner wall of the protection pipe or interface and cause damage, resulting in poor practical performance of the cable protection pipe.

[0005] Furthermore, when cable protection pipes are manually fitted onto the outside of the cable, one end of the cable may be bent inside the pipe as it passes through, affecting the normal installation of the cable and resulting in poor stability during the installation of the cable protection pipe.

Ring support members are connected to both ends of the upper protective tube. Several ring-shaped blocks are disposed outside the ring support members. A locking arc block is connected to each of the ring-shaped blocks. A limiting groove is provided in the locking arc block. A positioning member is connected to the ring support member. One end of the positioning member is disposed in the limiting groove. A handle is provided at the bottom of the guide ring. The handle is connected to one side of some of the ring-shaped blocks.

[0008] Preferably, the upper protective tube has several movable grooves inside, and a wall-supporting block is connected in the movable groove. The upper protective tube is provided with a guide limiting groove, which limits the wall-supporting block. A top support component is connected to the outside of the guide ring. The top support component is disposed in the movable groove and supports the wall-supporting block.

[0009] Preferably, the top support component includes several floating shafts, and a top support spring is provided on the outside of the floating shaft. One end of the top support spring is connected to the outer ring of the floating shaft. Several floating grooves are provided on the guide ring. The floating shaft and the top support spring are both disposed in the floating grooves. One end of the several floating shafts is connected to a floating arc plate, and several ball bearings are installed on one side of the floating arc plate.

[0010] Preferably, one end of the floating arc plate is connected to a limiting block, a plurality of positioning grooves are provided in the movable groove, a limiting boss is connected in the plurality of positioning grooves, a limiting spring is connected to one side of the limiting boss, and the limiting spring is disposed in the positioning groove.

[0011] Preferably, the upper protective tube has several rotating platforms inside, one of which is connected to the inner wall of the guide ring on the outside, and the top of one of the rotating platforms is connected to several ring rotating blocks. Nested arc plates are connected between each pair of the rotating platforms.

[0012] Preferably, the outer edge of the rotary table is provided with several through slots, the interior of the upper protective tube is provided with several guide rails, a cylinder is provided in the guide rails, the cylinder is provided in the through slots, a spring is provided inside the cylinder, a round shaft is installed in the cylinder, one end of the spring is connected to one end of the round shaft, and the other end of the round shaft is connected to an annular plate.

[0013] Preferably, the sleeve auxiliary mechanism includes several guide frames, which are connected to the lower protective tube. The guide frames are provided with guide grooves, and two sliders are installed on the several guide frames. The sliders are provided with perforated grooves, and springs are installed in the perforated grooves.

[0014] Preferably, each of the two sliders is provided with a sliding shaft, the sliding shaft is disposed in a slot with holes, the spring is sleeved on the outside of the sliding shaft, one end of the sliding shaft is connected to a retaining ring, one end of the retaining ring is provided with a retaining groove, and one end of the retaining ring is connected to a retaining block.

[0015] Preferably, the other end of the sliding shaft is connected to a retaining shaft, and the lower protective tube has a plurality of positioning holes, the retaining shaft being inserted into the positioning holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application utilizes the synchronous locking of the rotary locking arc block and the support top block to lock the cable protection pipe to the distribution cabinet interface by rotating the handle. This eliminates the need for personnel to weld the cable protection pipe to the distribution cabinet interface, thus solving the problem that the current installation of cable protection pipes requires welding to the distribution cabinet, and outdoor welding requires specialized welding equipment, which makes the installation of cable protection pipes very inconvenient. This is beneficial to improving the installation efficiency of cable protection pipes. 2. This application achieves the installation and fixation of the cable protection pipe by rotating the handle, and at the same time, it can drive the internal annular plate to be centered. In this way, the installation of the cable protection pipe can be completed by simply rotating the handle, and the cable is also centered and protected inside the protection pipe. This solves the problem that after the cable protection pipe is installed, the end of the cable entering the distribution cabinet will come into contact with the inner wall of the protection pipe or interface and rub against it, damaging the cable. In addition, when the cable is connected to the distribution cabinet, it may need to be split. The messy split wires are more likely to come into contact with the inner wall of the protection pipe or interface and are more likely to be damaged. This is conducive to improving the practical performance of the cable protection pipe. 3. This application guides the cable through the protective pipe by using an auxiliary mechanism. Personnel only need to push the cable, and the cable will pass through the protective pipe without bending. After the cable reaches the appropriate position, the cable will be automatically released, and personnel can continue to pull one end of the cable to connect it to the internal components of the distribution cabinet. This solves the problem that when the cable protective pipe is manually sleeved on the outside of the cable, one end of the cable may be bent in the protective pipe when passing through it, which affects the normal installation of the cable. This helps to improve the stability of the cable protective pipe installation. 4. This application utilizes a rotating handle to achieve the installation and fixing of the cable protection pipe with the distribution cabinet interface during the connection process. It also achieves centered protection of the cable inside the protection pipe. Both installation and disassembly are very convenient, greatly improving the efficiency of cable protection pipe installation for operators and significantly enhancing the ease of use of the cable protection pipe.

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Please see Figure 1 , Figure 2 , Figure 3A cable protection pipe sleeve auxiliary structure includes a distribution cabinet 1 and an interface 2 connected to the bottom of the distribution cabinet 1. A protection mechanism 3 is installed in the interface 2. The protection mechanism 3 includes a lower protection pipe 302 and an upper protection pipe 301. Both the upper protection pipe 301 and the lower protection pipe 302 are sleeved on the outside of the cable to protect the cable. The bottom of the lower protection pipe 302 is inserted into the ground. The upper protection pipe 301 is connected to the interface 2 of the distribution cabinet 1 and is used to install and fix the cable protection pipe. A docking mechanism 4 is provided in the upper protection pipe 301 and a sleeve auxiliary mechanism 30 is provided in the lower protection pipe 302. The docking mechanism 4 connects the protective pipe and cable to the interface 2 of the distribution cabinet 1, and the auxiliary mechanism 30 is installed to assist the cable in passing through the protective pipe; Please see Figures 4 to 7 The upper protective tube 301 has an interlayer. The docking mechanism 4 includes a guide ring 5, which is disposed in the interlayer. A connecting block is disposed in the interlayer of the upper protective tube 301, connecting the inner and outer layers of the upper protective tube 301. A connection port is disposed on the outside of the guide ring 5, located outside the connecting block. Specifically, when the guide ring 5 rotates in the upper protective tube 301, its connection port will rotate outside the connecting block, thereby ensuring that the guide ring 5 rotates normally in the interlayer of the upper protective tube 301. Several ring-rotating blocks 10 are connected to both ends of the guide ring 5. Ring support members 6 are connected to both ends of the upper protective tube 301. The ring-rotating blocks 10 are disposed outside the ring support members 6. A locking arc block 9 is connected to each of the ring-rotating blocks 10. The locking arc block 9 can be used in the working environment of the upper protective tube 301. The present invention retracts and extends a sufficient distance, solving the problem that the traditional rotary transmission and movement structure requires a guide groove to guide and cooperate to achieve movement and extension. Its movement and extension distance is limited by the guide groove, making it difficult to adapt to different working environments. Through the cooperation of the ring-shaped block 10 and the ring support 6, the rotating locking arc block 9 can extend a sufficient distance to cooperate with the interface 2 for the installation of the protective tube in a limited space. The rotating locking arc block 9 has a limit groove 8. The ring support 6 is connected to a positioning element 7, one end of which is set in the limit groove 8. The bottom of the guide ring 5 is provided with a handle 11, which is connected to one side of part of the ring-shaped block 10. By rotating the handle 11, the operator can drive the guide ring 5 to rotate in the interlayer of the upper protective tube 301. It should be noted that the rotation angle of the guide ring 5 is fixed and is not unlimited. When the guide ring 5 rotates, it drives the ring-shaped blocks 10 at both ends to rotate. Specifically, the ring-shaped blocks 10 rotate along the ring support 6 and are limited by the ring support 6 and the connecting block. More specifically, the ring support 6 is fixed by the upper protective tube 301. Therefore, when the ring-shaped blocks 10 rotate on the ring support 6, it will drive the rotating locking arc block 9 to move. At this time, the positioning part 7 on the ring support 6 is fixed. When the rotating locking arc block 9 moves, its limiting groove 8 will cooperate with the positioning part 7, so that the positioning part 7 will push the rotating locking arc block 9 out. It should be noted that several rotating locking arc blocks 9 will extend to the upper and lower ends of the interface 2. Therefore, the rotating locking arc blocks 9 at both ends of the upper protective tube 301 cooperate with the upper and lower ends of the interface 2 to realize the positioning and installation of the cable protection tube.

[0021] The upper protective tube 301 has several movable slots 12 inside, and a support block 13 is connected to the movable slot 12. The upper protective tube 301 is provided with a guide limiting slot. The support block 13 moves in the upper protective tube 301 through the guide limiting slot. This limiting structure is a conventional combination of a limiting block and a guide limiting slot, which is a conventional and well-known technology, so it will not be described in detail here. The guide limiting slot limits the support block 13. The guide ring 5 is connected to a top support component 14 on the outside. The top support component 14 is set in the movable slot 12 and supports the support block 13. When the guide ring 5 rotates, it will drive the top support component 14 to push out the support block 13, so that the support block 13 abuts against the inner wall of the interface 2, thereby further installing and fixing the cable protection tube. At this time, the installation and fixation of the cable protection pipe and the interface 2 are achieved by the cooperation of several rotating locking arc blocks 9 at both ends of the interface 2 and the wall support block 13 on the inner wall of the interface 2. This enables the cable protection pipe to be quickly installed and fixed to the interface 2 of the distribution cabinet 1. Specifically, as the guide ring 5 rotates, the top support component 14 will rotate to one side of the support block 13. During rotation, the floating shaft 16 and the top support spring 17 cooperate to make the floating shaft 16 move in the floating groove 15, driving the floating arc plate 18 and the ball 19 to continuously contact one side of the movable groove 12 until they contact one side of the floating arc plate 18. The top support spring 17 causes the floating arc plate 18 and the ball 19 to push the support block 13 out and abut against the inner wall of the interface 2 for fixation. It should be further explained that when the guide ring 5 rotates, the ball bearing 19 can maintain a certain degree of mobility, so that the guide ring 5 can drive the top support component 14 to rotate with the force of the operator. This avoids the problem that the force of the top support spring 17 will cause the friction of the top support component 14 to be too large and thus prevent it from rotating. In addition, the ball bearing 19 is installed in the constraint structure designed on the floating arc plate 18, which preserves the rolling freedom of the ball bearing 19. The installation of the ball bearing 19 is a well-known technology and is a conventional means that can be understood and implemented by those skilled in the art based on common sense. Therefore, it will not be described in detail here.

[0022] The top support component 14 includes several floating shafts 16. A top support spring 17 is provided on the outside of the floating shafts 16. One end of the top support spring 17 is connected to the outer ring of the floating shaft 16. Several floating grooves 15 are provided on the guide ring 5. The floating shafts 16 and the top support spring 17 are both provided in the floating grooves 15. One end of the several floating shafts 16 is connected to a floating arc plate 18. Several balls 19 are installed on one side of the floating arc plate 18.

[0023] One end of the floating arc plate 18 is connected to a limiting block 20. Several positioning slots 21 are provided in the movable groove 12. A limiting boss 22 is connected in the several positioning slots 21. A limiting spring 221 is connected to one side of the limiting boss 22. The limiting spring 221 is set in the positioning slot 21. It should be noted that when the floating arc plate 18 and the ball 19 move to the top block 13 of the ejector support wall, the floating arc plate 18 will reach the limiting position of the limiting boss 22. The limiting boss 22 limits the floating arc plate 18 and maintains the stability of the position of the top support component 14 when it is working. Specifically, when the floating arc plate 18 rotates and moves, it relies on the force of manually turning the handle 11. Under the manual action, the bottom of the floating arc plate 18 will drive the limiting block 20 to move and contact the limiting boss 22. The limiting boss 22 will block the floating arc plate 18 from rotating and moving. However, under the manual action, the floating arc plate 18 continues to move. The limiting block 20 and the floating arc plate 18 will squeeze the limiting boss 22, causing the limiting boss 22 to descend and sink into the positioning groove 21. At this time, the floating arc plate 18 can continue to move until it pushes out the support block 13. More specifically, the top of the limiting boss 22 is a sloping rounded corner boss, and the limiting block 20 is also a sloping platform. Therefore, when the sloping surface of the limiting block 20 of the floating arc plate 18 contacts the sloping surface of the limiting boss 22, and the limiting boss 22 forms a blocking positioning, the personnel need to increase the force. At this time, the sloping surface of the limiting block 20 will squeeze the sloping surface of the limiting boss 22. As the limiting block 20 and the floating arc plate 18 continue to rotate and move, the limiting boss 22 will compress the limiting spring 221 until the top surface of the limiting boss 22 is in the positioning groove 21. In this way, the floating arc plate 18 can continue to move. When the floating arc plate 18 moves into place, the limiting boss 22 rises under the reset force of the limiting spring 221, forming a limit on the floating arc plate 18 and keeping the floating arc plate 18 stably located on one side of the support block 13. During disassembly, the personnel need to twist the handle 11 to disassemble the protective tube. This will not be repeated here. When the top support component 14 stops pushing the top support block 13 out, the top support block 13 loses its supporting force on the inner wall of the interface 2, so the protective tube can be disassembled normally.

[0024] Please see Figure 8 , Figure 9The upper protective tube 301 has several rotating platforms 23 inside. The outer side of one rotating platform 23 is connected to the inner wall of the guide ring 5. The outer side of the lowest rotating platform 23 is provided with a connecting block, which penetrates the inner layer of the upper protective tube 301 and connects to the guide ring 5. In this way, when the guide ring 5 rotates, it will also drive the rotating platform 23 to rotate. It should be noted that the inner layer of the upper protective tube 301 has an L-shaped opening. During normal rotation, the connecting block on the outer side of the lowest rotating platform 23 will rotate on the short side of the L-shaped opening, thereby driving the rotating platform 23 to rotate. When the upper protective tube 301 is closed, the length of the L-shaped opening is... The edge will slide outside the connecting block to complete the overlap of one end of the upper protective tube 301 and the lower protective tube 302. The top of one of the rotating platforms 23 is connected to several ring rotating blocks 10. Several rotating platforms 23 are connected to each other by nested arc plates 24. There are multiple nested arc plates 24 to ensure the stability between the two rotating platforms 23. The nested arc plates 24 are nested layer by layer. In the initial state (the upper protective tube 301 is fitted on one end of the lower protective tube 302), the nested arc plates 24 are compressed between the three rotating platforms 23 to ensure that the upper protective tube 301 can be properly fitted on the outside of the lower protective tube 302. When installing the cable protection pipe, the upper protection pipe 301 needs to be moved to the inside of the interface 2 at one end of the lower protection pipe 302. At this time, the nested arc plate 24 is pulled out between the three rotating platforms 23 so that the three rotating platforms 23 maintain a suitable distance.

[0025] The outer edge of the rotary table 23 has several through slots 25, and the interior of the upper protective tube 301 has several guide rails. A cylinder 26 is installed in the guide rail, with one side of the cylinder 26 positioned in the guide rail to ensure that the guide rail can slide vertically on the outside of the cylinder 26 (this sliding is not the cylinder 26 sliding, but the sliding between the guide rail and the cylinder 26 when the upper protective tube 301 is retracted). At the same time, the cylinder 26 cannot move radially, so that when the rotary table 23 rotates, the cylinder 26 will remain radially fixed. The cylinder 26 is set in the through slots 25, and a spring 27 is installed inside the cylinder 26. The spring 27 is used to reset the annular plate 29 during disassembly. The spring 27 drives the circular shaft 28 to move in the cylinder 26, thereby driving the annular plate 29 to reset. The circular shaft 28 is installed in the cylinder 26, one end of the spring 27 is connected to one end of the circular shaft 28, and the other end of the circular shaft 28 is connected to the annular plate 29. When the handle 11 is manually turned, the guide ring 5 will also drive the bottom rotating platform 23 and the top rotating platform 23 to rotate synchronously through several ring rotating blocks 10 at the upper end of the interface 2. The two will drive the rotating platforms 23 between them to rotate synchronously. When the rotary table 23 rotates, the cylinder 26 remains radially fixed. Therefore, when the rotary table 23 rotates, the cylinder 26 will move in the through groove 25 of the rotary table 23. At this time, due to the influence of the curved shape of the through groove 25, the annular plate 29 will drive the circular shaft 28 to extend out of the cylinder 26. When it extends to the limited position, several annular plates 29 on a single rotary table 23 will form a circle to centrally protect the cable. It is important to note that the angles of the annular plates 29 on the middle rotating platform 23 and the upper and lower rotating platforms 23 are offset and complementary to avoid gaps in the annular plates 29 during synchronous centering, which could lead to the problem that the branch cables passing through the gaps cannot be protected by the annular plates 29. By rotating the handle 11, the cable protection pipe can be installed and fixed at the same time, and the internal annular plate 29 can be centered synchronously. In this way, the cable protection pipe can be installed by simply rotating the handle 11, and the cable can be centered and protected inside the protection pipe. This solves the problem that after the cable protection pipe is installed, the end of the cable entering the distribution cabinet 1 will come into contact with the inner wall of the protection pipe or interface 2 and rub against it, which will damage the cable. In addition, when the cable is connected to the distribution cabinet 1, it may need to be split, and the messy split wires are more likely to be damaged by contact with the inner wall of the protection pipe or interface 2.

[0026] Please see Figures 10 to 12 The cable installation auxiliary mechanism 30 includes several guide frames 31 connected to the lower protective tube 302. Each guide frame 31 has a guide groove 32, and two sliders 33 are mounted on each guide frame 31. Each slider 33 has a perforated groove 34, and a second spring 35 is installed in the perforated groove 34. When installing the cable, the operator inserts the cable through the bottom of the lower protective tube 302 into the installation auxiliary mechanism 30. The operator then connects two retaining rings 37, which cause the sliding shaft 36 to move within the perforated groove 34, compressing the second spring 35. The retaining shaft 38 then disengages from the positioning hole 39, thus securing the cable. Once the cable is in place, push it. The cable will cooperate with the retaining ring 37 to drive the slider 33 to slide in the guide groove 32 of the guide frame 31 until it reaches the top of the lower protective tube 302. When the slider 36 reaches the top of the lower protective tube 302, the spring 35 in the slot 34 with holes will push the retaining ring 38 into the positioning hole 39 above the lower protective tube 302. At the same time, the slider 36 will drive the retaining ring 37 to disengage. The cable will be released and the personnel can continue to hold one end of the cable to thread it through and introduce the cable into the distribution cabinet 1 for wiring. Then, install and fix the upper protective tube 301 to the interface 2 of the distribution cabinet 1 to complete the installation and fixation of the cable protection tube. By using an auxiliary mechanism 30 to guide the cable through the protective pipe, personnel only need to push the cable, and the cable can pass through the protective pipe without bending. After the cable reaches the appropriate position, the cable is automatically released, and personnel can continue to pull one end of the cable to connect it to the internal components of the distribution cabinet 1. This effectively avoids the problem of cable end bending when passing through the protective pipe.

[0027] Two sliders 33 are equipped with sliding shafts 36, which are located in slots 34 with holes. Spring 35 is sleeved on the outside of the sliding shafts 36. One end of the sliding shafts 36 is connected to a retaining ring 37. One retaining ring 37 has a retaining groove at one end, and the other retaining ring 37 is connected to a retaining block. The retaining rings 37 guide the cable through the cable and automatically release the cable after it reaches the appropriate position, ensuring that personnel can perform normal operations such as wiring the cable. This solves the problem that when the cable protection pipe is manually sleeved on the outside of the cable, one end of the cable may be bent in the protection pipe when passing through it, which affects the normal installation of the cable. This helps to improve the stability of the cable protection pipe during installation.

[0028] The other end of the sliding shaft 36 is connected to a retaining shaft 38. The lower protective tube 302 has several positioning holes 39, and the retaining shaft 38 is inserted into the positioning holes 39.

[0029] When using this invention: First, when installing the cable, the operator inserts the cable through the bottom of the lower protective tube 302, passing it through the installation auxiliary mechanism 30 at the bottom of the lower protective tube 302. The operator then connects the two retaining rings 37, which drive the sliding shaft 36 to move in the perforated groove 34, compressing the second spring 35. The retaining shaft 38 then disengages from the positioning hole 39, thus securing the cable. The cable can then be pushed, and the cable, in conjunction with the retaining rings 37, drives the slider 33 to slide in the guide groove 32 of the guide frame 31 until it reaches the lower... When the protective tube 302 is at the top, the sliding shaft 36, under the restoring force of the spring 35 in the slot 34, drives the retaining shaft 38 into the positioning hole 39 above the lower protective tube 302. At the same time, the sliding shaft 36 drives the retaining ring 37 to disengage, and the cable is released. The personnel can continue to hold one end of the cable to thread the cable and introduce the cable into the distribution cabinet 1 for wiring. Then, the upper protective tube 301 is installed and fixed to the interface 2 of the distribution cabinet 1 to complete the installation and fixing of the cable protection tube. Secondly, by rotating the handle 11, the guide ring 5 is rotated in the interlayer of the upper protective tube 301. When the guide ring 5 rotates, it will drive the ring blocks 10 at both ends to rotate. Specifically, the ring blocks 10 rotate along the ring support 6 and are limited by the ring support 6 and the connecting block. More specifically, the ring support 6 is fixed by the upper protective tube 301. Therefore, when the ring blocks 10 rotate on the ring support 6, it will drive the locking arc block 9 to move. At this time, the positioning part 7 on the ring support 6 is fixed. When the locking arc block 9 moves, its limiting groove 8 will cooperate with the positioning part 7, so that the positioning part 7 will push the locking arc block 9 out. It should be noted that several locking arc blocks 9 will extend to the upper and lower ends of the interface 2. Therefore, the locking arc blocks 9 at both ends of the upper protective tube 301 cooperate with the upper and lower ends of the interface 2 to realize the positioning and installation of the cable protection tube. Then, as the guide ring 5 rotates, the top support component 14 will rotate to one side of the support block 13. During rotation, the floating shaft 16 and the top support spring 17 cooperate to make the floating shaft 16 move in the floating groove 15, driving the floating arc plate 18 and the ball 19 to continuously contact one side of the movable groove 12 until they contact one side of the floating arc plate 18. The top support spring 17 causes the floating arc plate 18 and the ball 19 to push the support block 13 out and abut against the inner wall of the interface 2. When the floating arc plate 18 and the ball 19 move to push out the support block 13, the floating arc plate 18 will reach the limit position of the limiting boss 22. The limiting boss 22 limits the floating arc plate 18 to maintain the stability of the position of the top support component 14 during operation. Furthermore, when the handle 11 is manually turned, the guide ring 5 will also drive the lowermost rotating platform 23, and the guide ring 5 will drive the uppermost rotating platform 23 to rotate synchronously through several ring rotating blocks 10 at the upper end of the interface 2. The two will drive the rotating platforms 23 between them to rotate synchronously. When the rotating platform 23 rotates, the cylinder 26 remains radially fixed. Therefore, when the rotating platform 23 rotates, the cylinder 26 will move in the through groove 25 of the rotating platform 23. At this time, due to the influence of the curved surface shape of the through groove 25, the annular arc plate 29 will drive the circular shaft 28 to extend out of the cylinder 26. When it extends to the limited position, several of the rotating platforms 23 will rotate synchronously. The two annular plates 29 form a circle to centrally protect the cable. By rotating the handle 11, the cable protection tube is installed and fixed, and the internal annular plates 29 are also centered synchronously. In this way, the cable protection tube can be installed and the cable is centrally positioned and protected inside the protection tube by simply rotating the handle 11. This solves the problem that after the cable protection tube is installed, the end of the cable entering the distribution cabinet 1 will come into contact with the inner wall of the protection tube or interface 2 and rub against it, which will damage the cable. In addition, when the cable is connected to the distribution cabinet 1, it may need to be split. The messy split wires are more likely to come into contact with the inner wall of the protection tube or interface 2 and are more likely to be damaged. Finally, by using the rotating handle 11, the cable protection pipe can be installed and fixed at the interface of the distribution cabinet 1. At the same time, it also achieves the centered protection of the cable inside the protection pipe. Both installation and disassembly are very convenient, greatly improving the efficiency of operators in installing cable protection pipes and greatly improving the ease of use of cable protection pipes.
