Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of guyed towers, and particularly relates to a polyurethane glass fiber composite material communication guyed tower. BACKGROUND

[0002] The composite material is a composite material combined by two or more materials, and is a composite material combined by a reinforcing material and a base material. The guyed tower made of the polyurethane glass fiber composite material has scientific structural design and excellent strength, and the product life cycle is significantly prolonged. The pole body is light and has extremely strong corrosion resistance, and maintenance is not needed, so the polyurethane glass fiber composite material pole is an ideal choice for overhead power transmission and distribution lines. The polyurethane glass fiber composite material pole is much lighter than a traditional pole, and the weight of the polyurethane glass fiber composite material pole is only one eighth of that of an ordinary cement pole and one fifth of that of a steel pipe pole, so that the construction and installation of the polyurethane glass fiber composite material pole are extremely convenient and low in cost. In mountainous and hilly areas, rescue and disaster relief sites or environments with poor transportation conditions, the polyurethane glass fiber composite material pole has significant advantages and has been widely applied to the field of power transmission and distribution.

[0003] In the prior art, when a mounting hole needs to be formed in the guyed tower made of the polyurethane glass fiber composite material for connecting a guy wire or other components, although the guyed tower has high strength and high toughness and can withstand a large external impact force, the stress concentration point is formed in a local area after the hole is punched, which may cause micro-cracks or delamination in the material, especially when the hole diameter is large or the hole spacing is small, the stress concentration effect is more significant, which greatly reduces the overall carrying capacity of the tower and has a safety hazard. A common solution in the industry is to pre-plan the punching position in the design stage and optimize the hole layout through finite element simulation software, and metal bushings or local thickening are additionally arranged at key positions to enhance the strength, but these measures cannot completely cover the complex stress conditions in actual working conditions and cannot fundamentally eliminate the stress concentration tendency of the composite material, and the additional reinforcing parts may increase the manufacturing cost and assembly complexity.

[0004] Therefore, it is urgent to provide a polyurethane glass fiber composite material communication guyed tower to solve the above problems. SUMMARY

[0005] The technical problem to be solved by the application is to overcome the defects of the prior art and provide a polyurethane glass fiber composite material communication guyed tower.

[0006] The technical scheme adopted to solve the above technical problem is as follows: a polyurethane glass fiber composite material communication guyed tower, comprising a tower base, a first tower is fixedly arranged in the tower base, and a first circular conical pipe is integrally formed at the top end of the first tower.

[0007] The top end of the first circular spinal canal is attached with a second circular spinal canal, the bottom end of the second circular spinal canal is fixed with a connecting pipe penetrating through and extending into the first tower interior, and the top end of the second circular spinal canal is fixed with a second tower, and the top end of the second tower is fixed with a tower top cover.

[0008] The first circular spinal canal and the second circular spinal canal are externally provided with a connecting mechanism for preventing bolt loosening.

[0009] The connecting mechanism is externally provided with a loosening prevention mechanism for splicing and fixing, and the loosening prevention mechanism is externally provided with a splicing mechanism for installation without punching.

[0010] Through the above technical solution, the tower base is sleeved into the first tower from the top end of the first circular spinal canal, and the tower base is reliably limited and fixed to the first tower through appropriate process means such as welding or fastening connectors, etc., the second circular spinal canal is attached and installed at the top end of the first circular spinal canal, and the connecting pipe is fixed so that one end penetrates through and extends into the first tower interior, thereby enhancing the connection strength between the first tower and the second tower, and then the tower top cover is installed at the top end of the second tower to complete the construction of the tower main structure.

[0011] Further, the connecting mechanism includes a flange connecting ring sleeved outside the second circular spinal canal, the bottom end of the flange connecting ring is attached with a first lower spinal canal flange on one side, the bottom end of the flange connecting ring is attached with a second lower spinal canal flange on the other side, and the interiors of the first lower spinal canal flange and the second lower spinal canal flange are embeddedly installed with the exterior of the first circular spinal canal.

[0012] Through the above technical solution, the inner arc surfaces of the first lower spinal canal flange and the second lower spinal canal flange are adapted to the exterior of the first circular spinal canal, and the first lower spinal canal flange and the second lower spinal canal flange are embedded into the bottom end of the flange connecting ring from below so that the inner arc surfaces thereof are in complete contact with the outer wall of the first circular spinal canal.

[0013] Further, the top end of the flange connecting ring is attached with a first upper spinal canal flange on one side, the top end of the flange connecting ring is attached with a second upper spinal canal flange on the other side, the interiors of the first upper spinal canal flange and the second upper spinal canal flange are embeddedly installed with the exterior of the second circular spinal canal, and the interiors of the first upper spinal canal flange and the first lower spinal canal flange and the second upper spinal canal flange and the second lower spinal canal flange are threadedly installed with first bolts.

[0014] Through the above technical solution, the first upper spinal canal flange and the second upper spinal canal flange are embedded into the top end of the flange connecting ring from above so that the inner arc surfaces thereof are in complete contact with the outer wall of the second circular spinal canal, the first bolts are sequentially inserted, and are respectively screwed into the corresponding threaded holes of the first upper spinal canal flange and the first lower spinal canal flange, and the second upper spinal canal flange and the second lower spinal canal flange, so that the flange groups are tightly attached to the two ends of the flange connecting ring, and the final fixing is completed.

[0015] Further, the bottom end of the first and second lower spinal canal flanges and the top end of the first and second upper spinal canal flanges are fixed with clamping guide rails, and two flange sleeves are slidingly installed outside the four clamping guide rails, and one side of the first upper spinal canal flange is fixed with an anti-loose guide rail.

[0016] Through the above technical solution, the two flange sleeves are respectively sleeved into the two sides of the first and second lower spinal canal flanges, the first and second upper spinal canal flanges through the clamping guide rails, and then the first and second lower spinal canal flanges, the first and second upper spinal canal flanges are fixed and limited, preventing the loosening of the connection caused by the loosening of the bolts.

[0017] Further, the anti-loose mechanism includes two limiting blocks for fixing the two flange sleeves, one side of each of the two limiting blocks is fixed with a rod tower pull line ring, the top end of each of the two flange sleeves is fixed with a rod body sleeve, and the top end of each of the two limiting blocks is threadedly installed with a second bolt penetrating through one end and extending to the outside of the first lower spinal canal flange.

[0018] Through the above technical solution, when the flange sleeve slides along the clamping guide rail to the predetermined position, the limiting block will accurately position the flange sleeve, at this time, the threaded holes on the limiting block, the first and second upper spinal canal flanges, the first and second lower spinal canal flanges correspond to each other, then the second bolt is passed through the top end of the limiting block, and one end of the second bolt penetrates through and extends to the outside of the first lower spinal canal flange, by tightening the second bolt, the fixation between the components is realized, and the pull line pulled by the rod tower pull line ring is a polyurethane glass fiber composite material, which is lighter in weight than the existing metal pull line and is not easy to corrode.

[0019] Further, one end of one side of the rod body sleeve is slidingly installed with a first arc-shaped rod, one end of the other side of the rod body sleeve is slidingly installed with a second arc-shaped rod, the other end of one side of the rod body sleeve is slidingly installed with a third arc-shaped rod, and the other end of the other side of the rod body sleeve is slidingly installed with a fourth arc-shaped rod, and the top middle part of each of the first and second arc-shaped rods is fixed with a limiting plate.

[0020] Through the above technical solution, when the first, second, third and fourth arc-shaped rods are installed through the two rod body sleeves, the limiting plate will limit the top end of the two first bolts, and when subjected to external vibration or impact force, the first bolt cannot easily rotate around its axis due to the limiting action of the limiting plate on the top end of the first bolt, thereby always maintaining a fastened state, ensuring the stability of the connection part.

[0021] Furthermore, the splicing mechanism includes a first splicing plate fixed to one end of the second arc-shaped rod and the third arc-shaped rod respectively. A second splicing plate is fixed to one end of both the first arc-shaped rod and the fourth arc-shaped rod. One side of the first splicing plate and the second splicing plate are slidably connected to the anti-loosening guide rail. A plug-in plate that is fitted and connected to the second splicing plate is fixed to the bottom of one end of the first splicing plate.

[0022] Through the above technical solution, the second splicing plate of the first arc-shaped rod is aligned with the first splicing plate of the second arc-shaped rod. The first and second splicing plates are slid along the anti-loosening guide rail so that the insertion plate is embedded in the second splicing plate, thus completing the splicing. Similarly, the first splicing plate of the third arc-shaped rod can be spliced ​​with the second splicing plate of the fourth arc-shaped rod. After splicing, the first and second splicing plates will limit the tops of the two second bolts. When subjected to external vibration or impact, due to the limiting effect of the first and second splicing plates on the tops of the second bolts, the second bolts cannot easily rotate around their axes, thus always maintaining a tight state and ensuring the stability of the connection.

[0023] Furthermore, an arc-shaped spring is fixed to the inner wall of the second splicing plate, and an arc-shaped slider is fixed to one end of each arc-shaped spring. An arc-shaped insert rod is fixed to the top end of one end of the first splicing plate.

[0024] Through the above technical solution, the first splicing plate and the second splicing plate are initially spliced ​​together by the plug-in plate. The arc-shaped plug will be inserted into the interior of the second splicing plate. As the arc-shaped plug is inserted, the arc-shaped slider moves towards the arc-shaped spring under the push of the arc-shaped plug, and squeezes the arc-shaped spring. At this time, when the arc-shaped slider moves to the position where the fixing hole is exposed, it is convenient to pass the connector through the fixing hole to fix the first splicing plate and the second splicing plate together.

[0025] Furthermore, a spring shell is fixed to the top of the second splicing plate, and a spring insert rod with one end penetrating and extending into the interior of the second splicing plate is slidably installed inside the spring shell. A spring pull rod with one end penetrating and extending into the exterior of the spring shell is fixed to the top of the spring insert rod, and a columnar spring is fixed between the top of the spring insert rod and the inner top wall of the spring shell.

[0026] With the above technical solution, when the arc-shaped insert is not inserted into the second splicing plate, the arc-shaped slider blocks the spring insert. As the arc-shaped insert is inserted, the arc-shaped slider that was blocking the spring insert will shift, releasing the restriction on the spring insert. Once the arc-shaped slider no longer blocks, the cylindrical spring immediately exerts its elastic effect, driving the spring insert to slide downward along the inside of the spring shell until the spring insert is fully inserted into the fixing hole, completing the splicing and fixing of the first and second splicing plates. When it is necessary to disassemble the two splicing plates, the operator only needs to hold the spring pull rod and apply an upward pulling force. Since the spring pull rod and the spring insert are fixedly connected, this pulling force will be transmitted to the spring insert, causing it to overcome the elastic force of the cylindrical spring and slide upward along the inside of the spring shell, pulling it out of the fixing hole. As the spring insert is pulled out, the connection between the first and second splicing plates is released, and they can then be easily separated, completing the disassembly operation.

[0027] The beneficial effects of this invention are as follows:

[0028] (1) This invention is equipped with an anti-loosening mechanism and a splicing mechanism, and adopts a special locking device. When the first bolt and the second bolt are tightened, the locking device will lock the top of the bolt so that it cannot be easily rotated, thereby effectively preventing the bolt from loosening and ensuring the stability of the connection between the first tower and the second tower. Even when facing interference from the external environment, such as strong winds and vibrations, it can greatly reduce the damage to the connection caused by these factors and ensure the safety of the overall tower structure.

[0029] (2) By providing a connecting mechanism, the first conical tube and the second conical tube can be connected and fixed from top to bottom without drilling holes in the guyed tower. This fundamentally eliminates the stress concentration problem caused by drilling, improves the overall load-bearing capacity and safety of the tower, avoids the use of additional reinforcements such as metal bushings, reduces manufacturing costs and assembly complexity, and makes the entire tower construction process more efficient and economical.

[0030] (3) The present invention uses an anti-loosening mechanism to splice and fix the vertical flange by using the installation structure of the tower guy wire ring. This design further optimizes the connection method, making the connection between towers more stable and reliable. At the same time, it makes full use of the existing tower structure characteristics, improves the overall compatibility and practicality. The tower guy wire used is also made of polyurethane glass fiber composite material to solve the problems of heavy weight and easy corrosion of existing metal guy wires. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] like Figures 1-11As shown, a polyurethane fiberglass composite communication guyed tower of this embodiment includes a tower base 1, a first tower 2 nested and fixed inside the tower base 1, a first conical tube 3 integrally formed at the top of the first tower 2, a second conical tube 4 fitted to the top of the first conical tube 3, a connecting pipe 5 fixed at the bottom end of the second conical tube 4 that extends through and into the interior of the first tower 2, a second tower 6 fixed at the top of the second conical tube 4, and a tower top cover 7 fixed at the top of the second tower 6; a connecting mechanism 8 for preventing bolt loosening is provided on the outside of the first conical tube 3 and the second conical tube 4.The connecting mechanism 8 includes a flange connecting ring 801 sleeved on the outside of the second conical tube 4. A first lower conical tube flange 802 is attached to one side of the bottom end of the flange connecting ring 801, and a second lower conical tube flange 803 is attached to the other side of the bottom end of the flange connecting ring 801. The interiors of the first lower conical tube flange 802 and the second lower conical tube flange 803 are fitted into the exterior of the first conical tube 3. A first upper conical tube flange 804 is attached to one side of the top end of the flange connecting ring 801, and a second upper conical tube flange 805 is attached to the other side of the top end of the flange connecting ring 801. The interiors of the first upper conical tube flange 804 and the second upper conical tube flange 805 are fitted into the exterior of the second conical tube 4. The first upper conical tube flange 804 and the first lower conical tube flange 802... Both the second upper conical flange 805 and the second lower conical flange 803 are threaded with first bolts 806. The bottom ends of the first lower conical flange 802 and the second lower conical flange 803, and the top ends of the first upper conical flange 804 and the second upper conical flange 805 are fixed with snap-fit ​​guide rails 807. Two flange sleeves 808 are slidably installed on the outside of the four snap-fit ​​guide rails 807. An anti-loosening guide rail 809 is fixed to one side of the first upper conical flange 804. The tower base 1 is inserted from the top of the first conical pipe 3 into the outside of the first tower 2. Using appropriate processes, such as welding or fastening connectors, the tower base 1 reliably limits and fixes the first tower 2. The second conical pipe 4 is then fitted snugly onto the first conical pipe. The top end of pipe 3 is fixed with connecting pipe 5, so that one end of it passes through and extends into the interior of the first tower 2, thereby enhancing the connection strength between the first tower 2 and the second tower 6. Then, the tower top cover 7 is installed on the top of the second tower 6, completing the construction of the main structure of the tower. The inner arc surfaces of the first lower conical pipe flange 802 and the second lower conical pipe flange 803 are adapted to the outer surface of the first conical pipe 3. The first lower conical pipe flange 802 and the second lower conical pipe flange 803 are inserted into the bottom end of the flange connecting ring 801 from below, so that their inner arc surfaces are in complete contact with the outer wall of the first conical pipe 3. The first upper conical pipe flange 804 and the second upper conical pipe flange 805 are inserted into the top end of the flange connecting ring 801 from above, so that their inner arc surfaces are in contact with the second conical pipe 4. With the outer wall fully in contact, the first bolt 806 is inserted sequentially and screwed into the corresponding threaded holes of the first upper vertebral flange 804 and the first lower vertebral flange 802, and the second upper vertebral flange 805 and the second lower vertebral flange 803, respectively. This ensures that each flange assembly fits tightly against both ends of the flange connecting ring 801, completing the final fixation. Two flange sleeves 808 are then fitted onto both sides of the first lower vertebral flange 802, the second lower vertebral flange 803, the first upper vertebral flange 804, and the second upper vertebral flange 805 via the clamping guide rails 807. This further limits and fixes the first lower vertebral flange 802, the second lower vertebral flange 803, the first upper vertebral flange 804, and the second upper vertebral flange 805, preventing the bolts from loosening and causing the connection to shift.

[0045] like Figures 5-10As shown, the connecting mechanism 8 is externally provided with an anti-loosening mechanism 9 for splicing and fixing it. The anti-loosening mechanism 9 includes two limiting blocks 901 for fixing the two flange sleeves 808. A tower guy wire ring 902 is fixed to one side of each of the two limiting blocks 901. A pole body sleeve 903 is fixed to the top of each of the two flange sleeves 808. A second bolt 904 is threaded onto the top of each of the two limiting blocks 901, with one end penetrating and extending to the outside of the first lower conical flange 802. A rod body sleeve 903 is slidably installed at one end of one side of the pole body sleeve 903. A first arc-shaped rod 905 is slidably mounted on one end of a rod body sleeve 903 on the other side, a second arc-shaped rod 906 is slidably mounted on the other end of a rod body sleeve 903 on one side, a third arc-shaped rod 907 is slidably mounted on the other end of a rod body sleeve 903 on the other side, and a fourth arc-shaped rod 908 is slidably mounted on the other end of a rod body sleeve 903 on the other side. Limiting plates 909 are fixed to the middle of the top ends of both the first arc-shaped rod 905 and the second arc-shaped rod 906. When the flange sleeve 808 slides into the predetermined position along the locking guide rail 807, the limiting block 901 will accurately engage the flange sleeve 808. Positioning is then performed, at which point the threaded holes on the limiting block 901, the first upper vertebral tube flange 804, the first lower vertebral tube flange 802, the second upper vertebral tube flange 805, and the second lower vertebral tube flange 803 correspond to each other. Next, the second bolt 904 is passed through the top of the limiting block 901, with one end extending through and to the outside of the first lower vertebral tube flange 802. Tightening the second bolt 904 secures the components. When the first arc-shaped rod 905, the second arc-shaped rod 906, the third arc-shaped rod 907, and the fourth arc-shaped rod 90... 8. After installation via two pole body sleeves 903, the limiting plate 909 will limit the tops of the two first bolts 806. When subjected to external vibration or impact, due to the limiting effect of the limiting plate 909 on the tops of the first bolts 806, the first bolts 806 cannot easily rotate around their axis, thus always maintaining a tight state and ensuring the stability of the connection. The guy wire pulled by the tower guy wire ring 902 is made of polyurethane glass fiber composite material, which is lighter and less prone to corrosion than the existing metal guy wire.

[0046] like Figures 9-11As shown, the anti-loosening mechanism 9 is externally equipped with a splicing mechanism 10 that allows for installation without drilling. The splicing mechanism 10 includes a first splicing plate 1001 fixed to one end of the second arc-shaped rod 906 and the third arc-shaped rod 907, respectively. A second splicing plate 1002 is fixed to one end of both the first arc-shaped rod 905 and the fourth arc-shaped rod 908. One side of the first splicing plate 1001 and the second splicing plate 1002 is slidably connected to the anti-loosening guide rail 809. A plug-in plate 1003 that fits into the second splicing plate 1002 is fixed to the bottom of one end of the first splicing plate 1001. An arc-shaped spring 1004 is fixed to the inner wall of the second splicing plate 1002. An arc-shaped slider 1005 is fixed to one end of each arc-shaped spring 1004. An arc-shaped plug-in plate 1005 is fixed to the top of one end of the first splicing plate 1001. A spring housing 1007 is fixed to the top of the second splicing plate 1002, and a spring insert rod 1008 is slidably installed inside the spring housing 1007, with one end penetrating and extending into the interior of the second splicing plate 1002. A spring pull rod 1009 is fixed to the top of the spring insert rod 1008, with one end penetrating and extending out of the spring housing 1007. A columnar spring 1010 is fixed between the top of the spring insert rod 1008 and the inner top wall of the spring housing 1007. The second splicing plate 1002 of the first arc-shaped rod 905 is aligned with the first splicing plate 1001 of the second arc-shaped rod 906. The first splicing plate 1001 and the second splicing plate 1002 are slid along the anti-loosening guide rail 809, so that the insert plate 1003 is embedded in the second splicing plate 1002, completing the splicing. The first splicing plate 1001 of the third arc-shaped rod 907 can be spliced ​​with the second splicing plate 1002 of the fourth arc-shaped rod 908. After splicing, the first splicing plate 1001 and the second splicing plate 1002 will limit the tops of the two second bolts 904. When subjected to external vibration or impact, due to the limiting effect of the first splicing plate 1001 and the second splicing plate 1002 on the tops of the second bolts 904, the second bolts 904 cannot easily rotate around their axis, thus always maintaining a tight state and ensuring the stability of the connection. The first splicing plate 1001 and the second splicing plate 1002 are initially spliced ​​through the insertion plate 1003, and the arc-shaped insertion rod 1006 will be inserted into the second splicing plate 1002. As the arc-shaped insertion rod 1006... Upon insertion, the arc-shaped slider 1005 moves towards the arc-shaped spring 1004 under the push of the arc-shaped insert rod 1006, compressing the arc-shaped spring 1004. At this point, the arc-shaped slider 1005 moves to the position where it exposes the fixing hole, facilitating the connection piece to pass through the fixing hole and fix the first splicing plate 1001 and the second splicing plate 1002 together. Before the arc-shaped insert rod 1006 is inserted into the second splicing plate 1002, the arc-shaped slider 1005 blocks the spring insert rod 1008. As the arc-shaped insert rod 1006 is inserted, the arc-shaped slider 1005, which was originally blocking the spring insert rod 1008, will shift, releasing the restriction on the spring insert rod 1008. Once the arc-shaped slider 1005 no longer blocks, the cylindrical spring 1010 immediately exerts its elastic effect.The drive spring rod 1008 slides downwards along the inside of the spring housing 1007 until it is fully inserted into the fixing hole, completing the splicing and fixing of the first splicing plate 1001 and the second splicing plate 1002. When it is necessary to disassemble the two spliced ​​plates, the operator only needs to hold the spring pull rod 1009 and apply an upward pulling force. Since the spring pull rod 1009 is fixedly connected to the spring rod 1008, this pulling force will be transmitted to the spring rod 1008, causing it to overcome the elastic force of the cylindrical spring 1010 and slide upwards along the inside of the spring housing 1007, pulling it out of the fixing hole. As the spring rod 1008 is pulled out, the connection between the first splicing plate 1001 and the second splicing plate 1002 is released, allowing them to be easily separated, completing the disassembly operation.

[0047] The working principle of this embodiment is as follows: The tower base 1 is inserted from the top of the first conical tube 3 into the outside of the first tower 2. Using appropriate processes, such as welding or fastening connectors, the tower base 1 reliably limits and fixes the first tower 2. The second conical tube 4 is fitted to the top of the first conical tube 3, and the connecting pipe 5 is fixed, with one end penetrating and extending into the interior of the first tower 2, thereby enhancing the connection strength between the first tower 2 and the second tower 6. Then, the tower top cover 7 is installed on the top of the second tower 6, completing the construction of the main tower structure. The inner arc surfaces of the first lower conical tube flange 802 and the second lower conical tube flange 803 are adapted to the outer surface of the first conical tube 3. The first lower conical tube flange 802 and the second lower conical tube flange 803 are then connected... 3. Insert the flange connecting ring 801 from below, ensuring its inner arc surface is in complete contact with the outer wall of the first conical tube 3. Insert the first upper conical tube flange 804 and the second upper conical tube flange 805 from above, ensuring their inner arc surfaces are in complete contact with the outer wall of the second conical tube 4. Insert the first bolt 806 sequentially, screwing it into the corresponding threaded holes of the first upper conical tube flange 804 and the first lower conical tube flange 802, and the second upper conical tube flange 805 and the second lower conical tube flange 803, respectively, so that each flange assembly fits tightly against both ends of the flange connecting ring 801, completing the final fixation. Then, insert the two flange sleeves 808 into the first lower conical tube flange 802, the second lower conical tube flange 803, the first upper conical tube flange 804, and the second upper conical tube flange 803 respectively via the clamping guide rail 807. On both sides of 805, the first lower vertebral flange 802, the second lower vertebral flange 803, the first upper vertebral flange 804, and the second upper vertebral flange 805 are limited and fixed to prevent the bolts from loosening and causing the connection to loosen. When the flange sleeve 808 slides into the predetermined position along the snap-fit ​​guide rail 807, the limiting block 901 will accurately position the flange sleeve 808. At this time, the threaded holes on the limiting block 901, the first upper vertebral flange 804, the first lower vertebral flange 802, the second upper vertebral flange 805, and the second lower vertebral flange 803 correspond to each other. Then, the second bolt 904 is passed through the top of the limiting block 901, and one end of it passes through and extends to the outside of the first lower vertebral flange 802. By tightening the second bolt 904, the connection of each component is achieved. The guy wire, which is pulled by the guy wire ring 902, is made of polyurethane glass fiber composite material, which is lighter and less prone to corrosion than existing metal guy wires. After the first arc-shaped rod 905, the second arc-shaped rod 906, the third arc-shaped rod 907, and the fourth arc-shaped rod 908 are installed through the two rod body sleeves 903, the limiting plate 909 limits the tops of the two first bolts 806. When subjected to external vibration or impact, the first bolts 806 cannot easily rotate around their axis due to the limiting effect of the limiting plate 909, thus maintaining a tight state and ensuring the stability of the connection. The second splicing plate 1002 of the first arc-shaped rod 905 is aligned with the first splicing plate 1001 of the second arc-shaped rod 906.Slide the first splicing plate 1001 and the second splicing plate 1002 along the anti-loosening guide rail 809 so that the insertion plate 1003 is embedded in the second splicing plate 1002, completing the splicing. Similarly, the first splicing plate 1001 of the third arc-shaped rod 907 can be spliced ​​with the second splicing plate 1002 of the fourth arc-shaped rod 908. After splicing, the first splicing plate 1001 and the second splicing plate 1002 will limit the top ends of the two second bolts 904. When subjected to external vibration or impact, due to the limiting effect of the first splicing plate 1001 and the second splicing plate 1002 on the top ends of the second bolts 904, the second bolts 904 cannot rotate around their axis. The easy rotation ensures a secure connection and stability. After the first splicing plate 1001 and the second splicing plate 1002 are initially joined using the insertion plate 1003, the arc-shaped insertion rod 1006 is inserted into the second splicing plate 1002. As the arc-shaped insertion rod 1006 is inserted, the arc-shaped slider 1005 moves towards the arc-shaped spring 1004 under its push, compressing the spring. When the arc-shaped slider 1005 moves to the position where the fixing hole is exposed, it facilitates the connection of the first splicing plate 1001 and the second splicing plate 1002 through the connecting piece. When the arc-shaped insert 1006 is not inserted into the second splicing plate 1002, the arc-shaped slider 1005 blocks the spring insert 1008. As the arc-shaped insert 1006 is inserted, the arc-shaped slider 1005, which was originally blocking the spring insert 1008, will shift, releasing the restriction on the spring insert 1008. Once the arc-shaped slider 1005 no longer blocks, the cylindrical spring 1010 immediately exerts its elastic effect, driving the spring insert 1008 to slide downward along the inside of the spring shell 1007 until the spring insert 1008 is fully inserted into the fixing hole, completing the connection between the first splicing plate 1001 and the second splicing plate 1002. For the splicing and fixing of panel 1002, when it is necessary to disassemble the two spliced ​​panels, the operator only needs to hold the spring lever 1009 and apply an upward pulling force. Since the spring lever 1009 is fixedly connected to the spring insert 1008, this pulling force will be transmitted to the spring insert 1008, causing it to overcome the elastic force of the cylindrical spring 1010 and slide upward along the inside of the spring housing 1007, pulling it out of the fixing hole. As the spring insert 1008 is pulled out, the connection between the first splicing panel 1001 and the second splicing panel 1002 is released, and they can then be easily separated, completing the disassembly operation.
