[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] This utility model provides a locking protective tube for tidying up overhead communication lines. It can protect the lines and keep them neat and aesthetically pleasing, facilitating subsequent maintenance.
[0028] Please refer to this as well. Figures 1 to 3 The locking protective tube provided by this utility model includes a protective tube body 10 and a locking assembly 20.
[0029] The protective tube body 10 has a notch 11 along its axial direction, which penetrates the protective tube body 10 and allows the optical cable 40 to be inserted into the inner cavity of the protective tube body 10. The inner wall of the protective tube body 10 has a groove 12, with retaining parts 13 on both sides of the groove 12. The two retaining parts 13 and the inner wall of the groove 12 form a suspension groove 15, which accommodates the suspension wire 30, suspending the communication line in the air. A locking assembly 20 is located outside the protective tube body 10 and is used to lock the protective tube body 10 circumferentially from the outside.
[0030] The protective pipe body 10 is made of high-density polyethylene (HDPE), which has excellent chemical stability, corrosion resistance, and mechanical strength. It can withstand certain pressure and external forces and is not easily broken or damaged. Furthermore, HDPE also has good wear resistance and weather resistance, allowing for long-term use under various environmental conditions.
[0031] In use, the optical cable 40 of the communication line is inserted into the inner cavity of the protective tube body 10 through the notch 11 of the protective tube body 10, and then the suspension wire 30 is inserted into the suspension wire groove 15 formed by the two holding parts 13 and the inner wall of the groove 12. The holding parts 13 clamp the suspension wire 30 for limiting and fixing, and finally the protective tube body 10 is locked from the outside of the protective tube body 10 along the circumferential direction by the locking assembly 20.
[0032] With this configuration, the optical cable 40 of the communication line is encased in the protective tube body 10, which provides protection for the optical cable 40, effectively preventing damage to the optical cable 40 under harsh environments or external forces, thus extending the service life of the communication line. Furthermore, the optical cable 40 is entirely contained within the inner cavity of the protective tube body 10, rather than being haphazardly distributed, resulting in a neat and aesthetically pleasing communication line. The locking assembly 20 circumferentially locks the protective tube body 10 from the outside, connecting the protective tube body 10 to the optical cable 40 and the suspension wire 30, preventing the optical cable 40 and suspension wire 30 from detaching from the protective tube and ensuring the safety and stability of the communication line.
[0033] Please refer to this as well. Figures 1 to 3 The groove 12 is arc-shaped, and the retaining part 13 is arc-shaped. Since the cross-section of the suspension line 30 is circular, the suspension line groove 15 formed by the inner wall of the arc-shaped groove 12 and the inner walls of the two arc-shaped retaining parts 13 can fully fit with the suspension line 30, playing a limiting and fixing role and preventing the suspension line 30 from loosening.
[0034] Please refer to this as well. Figures 1 to 3 The groove 12 is located at the top of the inner wall of the protective tube body 10. One side of the retaining part 13 is fixedly connected to the inner wall of the protective tube body 10, and the other side is a free end. In use, the hanging wire 30 is inserted from between the free ends of the two retaining parts 13 into the hanging wire groove 15 formed by the two retaining parts 13 and the inner wall of the groove 12.
[0035] It should be noted that the specifications of the protective tube body 10 and the hanging groove 15 should be selected according to the actual application scenario. In this embodiment, the diameter of the protective tube body 10 is 50mm, the diameter of the arc-shaped groove 12 is 7mm, the distance between the free ends of the two holding parts 13 is 5mm, and the size of the notch 11 in the protective tube body 10 is 10mm. Optionally, the commonly used diameters of the protective tube body 10 are 40mm, 50mm, 60mm, 70mm, 80mm, etc., and the length of the protective tube body 10 is not limited.
[0036] Preferably, in some embodiments, the locking assembly 20 includes a fixing member 21 and a connecting strap 22, one end of the connecting strap 22 is fixedly disposed on the fixing member 21, the fixing member 21 is provided with a buckle hole, and the connecting strap 22 is provided with a buckle block for engaging with the buckle hole.
[0037] One end of the connecting strap 22 is fixedly connected to the fixing member 21. When in use, the connecting strap 22 is wrapped around the outer periphery of the protective tube body 10. By pressing, the buckle at the other end of the connecting strap 22 is fastened to the buckle hole of the fixing member 21, thereby locking the protective tube body 10. The operation is simple.
[0038] Preferably, in some embodiments, the locking assembly 20 includes a fixing member 21 and a connecting strap 22, one end of the connecting strap 22 is fixedly disposed on the fixing member 21, the fixing member 21 is provided with a buckle block, the connecting strap 22 is provided with a buckle hole, and the buckle block is used to engage with the buckle hole.
[0039] One end of the connecting strap 22 is fixedly connected to the fixing member 21. When in use, the connecting strap 22 is wrapped around the outer periphery of the protective tube body 10. By pressing, the buckle hole at the other end of the connecting strap 22 is fastened to the buckle block of the fixing member 21, thereby locking the protective tube body 10. The operation is simple.
[0040] Preferably, in some embodiments, the locking assembly 20 includes a fastener 21 and a connecting strap 22.
[0041] The connecting belt 22 is uniformly provided with continuous toothed racks, which are arranged along the extension direction of the connecting belt 22, and one end of the connecting belt 22 is fixedly provided to the fixing member 21.
[0042] The fastener 21 has a through hole for the connecting belt 22 to pass through. The fastener 21 is rotatably provided with a ratchet for engaging with a rack. The fastener 21 is also provided with a pawl, which is rotatably provided with the fastener 21 by a torsion spring. The pawl is used to engage with the ratchet to limit the rotation of the ratchet.
[0043] One end of the connecting strap 22 is fixedly connected to the fixing member 21. In use, the connecting strap 22 surrounds the outer circumference of the protective tube body 10, and the other end of the connecting strap 22 passes through the through hole of the fixing member 21. The rack on the connecting strap 22 engages with the ratchet inside the fixing member 21. As the connecting strap 22 moves, after the connecting strap 22 locks the protective tube body 10, the ratchet is rotated to lock the ratchet with the ratchet, so that the ratchet cannot rotate and the connecting strap 22 cannot move through the through hole, thus realizing the connection and fixation between the connecting strap 22 and the fixing member 21.
[0044] The pawl is rotatably mounted via a torsion spring. Under the elastic force of the torsion spring, the pawl engages with the ratchet. When the connecting belt 22 moves through the through hole, it causes the pawl to rotate against the torsion spring. At this time, the pawl is no longer engaged with the ratchet, and the ratchet can rotate. The rack on the connecting belt 22 can move in cooperation with the ratchet. When the connecting belt 22 moves into position, it causes the pawl to engage with the ratchet again, restricting the rotation of the ratchet. The fixing member 21 is connected and fixed to the connecting belt 22, thereby locking the protective tube body 10.
[0045] Please refer to this as well. Figures 1 to 3 The outer wall of the protective tube body 10 is also provided with several sets of fixing ring assemblies. The fixing ring assembly includes at least two fixing rings 14 arranged circumferentially along the protective tube body 10. The fixing rings 14 are used to connect the belt 22 through which the fixing ring assembly is arranged along the axial direction of the protective tube body 10.
[0046] In use, the connecting strap 22 in the locking assembly 20 passes through the fixing ring 14 and wraps around the outside of the protective tube body 10. In this embodiment, the fixing ring assembly includes two fixing rings 14, and one end of the connecting strap 22 passes through the two fixing rings 14 in sequence and connects to the fixing member 21, thereby locking the protective tube body 10.
[0047] Preferably, the fixing ring assembly and the locking assembly 20 correspond one-to-one. Several sets of fixing ring assemblies are arranged along the axial direction of the protective tube body 10. Each set of fixing ring assemblies works in conjunction with a set of locking assemblies 20. Under the action of the fixing ring assembly and the locking assembly 20, the protective tube body 10 is locked along the axial direction, which improves the locking effect and ensures the safety and stability of the communication line.
[0048] Optionally, one of the retaining rings 14 in the retaining ring assembly is threaded with a bolt for securing the connecting band 22. When the locking assembly 20 is not in use, the connecting band 22 in the retaining ring assembly can pass through the retaining ring 14. The bolt is threaded to the retaining ring 14. As the bolt rotates, one end of the bolt enters the interior of the retaining ring 14 and abuts against the connecting band 22. The abutment between the bolt and the connecting band 22 secures the connecting band 22, thereby fixing the locking assembly 20 to the protective tube body 10. The locking assembly 20 is less likely to fall off or be lost.
[0049] The specific usage process of the locking-type protective tube provided by this utility model is as follows:
[0050] Step 1: Conduct on-site surveys of areas where overhead communication lines need to be reorganized or where new overhead communication poles need to be built to determine the specifications of the protective pipe body 10 to be used for overhead communication lines;
[0051] Step 2: After the installation of the suspension line 30 is completed, it is not necessary to fix the communication optical cable 40. For existing overhead communication poles, the original iron wires, cable ties and other fixing materials need to be removed, and the discarded and excess optical cable 40 should be cut off.
[0052] Step 3: After completing the above steps, cut the protective tube body 10 corresponding to the length of the overhead communication line. At the end of the overhead line on the communication pole, put the optical cable 40 into the protective tube body 10, insert the suspension wire 30 into the suspension wire groove 15, and lock it with the locking component 20.
[0053] The locking protective tube provided by this utility model can be used for a long time and reused. The optical cable 40 of the communication line is wrapped by the protective tube body 10, which provides protection for the optical cable 40, effectively preventing damage to the optical cable 40 under harsh environments or external forces, and extending the service life of the communication line. Moreover, the optical cable 40 is completely contained within the inner cavity of the protective tube body 10, rather than being randomly distributed, thus making the communication line neat and aesthetically pleasing. The locking assembly 20 locks the protective tube body 10 circumferentially from the outside, realizing the connection between the protective tube body 10, the optical cable 40, and the suspension wire 30. The optical cable 40 and the suspension wire 30 will not detach from the protective tube, ensuring the safety and stability of the communication line.
[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0055] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
