Description

Technical Field

[0001] This utility model relates to the field of protective structure technology, and in particular to a protective structure for communication optical cables. Background Technology

[0002] Optical cables are an essential component in information communication. Communication optical cables consist of a cable core composed of several optical fibers (generally ranging from a few cores to thousands of cores) and an outer sheath.

[0003] During the laying of optical cables, sometimes the cables are not laid in a straight line. Due to external forces, certain points on the cable need to be bent to achieve the required angle. For example, the prior art disclosed in Chinese Patent Publication No. "CN220584459U" describes a protective structure for information communication optical cables. This utility model relates to the field of communication optical cable technology and includes a first plate and a second plate. Guide wheels are provided on the upper part of both the first and second plates, and shafts are provided at the corners of both sides of the first plate. Positioning plates are bolted to the corners of both sides of the second plate. The two positioning plates are rotatably fitted onto the outside of the two shafts. A bending adjustment part is provided between the bottom of the first and second plates. This information communication optical cable protective structure allows the optical cable to be bent by passing it through guide cylinders on the two plates and then rotating a knob to rotate the first plate.

[0004] However, most existing optical fiber cable protection structures can only accommodate a single arc requirement when bending the optical fiber cable. However, in the actual laying process, the optical fiber cable faces a variety of bending requirements, and this single arc bending capability obviously cannot meet the complex and ever-changing environmental requirements.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 A protective structure for a communication optical cable includes two opposing plates 1, which are rotatably connected by a connecting component 2. Each plate 1 has a limiting member 12 fixedly connected to the edge of its upper surface. A limiting tube 121 is fixedly connected to the limiting member 12, and clamping components 3 are provided at both ends of the limiting tube 121. An adjusting component 4 is slidably connected to each plate 1. A positioning component 5 for positioning the adjusting component 4 is provided inside each plate 1, and a locking component 6 for fixing the positioning component 5 is provided on the side of each plate 1.

[0027] In this embodiment, the clamping assembly 3 includes an inner shell 31 and an outer shell 32;

[0028] The outer shell 32 is rotatably connected to the limiting tube 121. The outer shell 32 is provided with a plurality of arc-shaped grooves 321. Each arc-shaped groove 321 is slidably connected to a vertical rod 33. A plurality of connecting rods 34 are rotatably connected inside the inner cavity of the outer shell 32. Each connecting rod 34 is rotatably connected to a clamping block 35 at the other end.

[0029] The inner shell 31 is fixedly connected to the limiting tube 121, the upright rod 33 is fixedly connected to the inner shell 31, one end of the clamping block 35 is rotatably connected to the inner shell 31, and a compression spring 36 is fixedly connected between the clamping block 35 and the inner shell 31. The top of the upright rod 33 is also provided with an external ladder platform, which is engaged with the outer side of the arc groove 321 to prevent the outer shell 32 from falling off. The clamping block 35 is made of rubber. When the outer shell 32 is rotated, the connecting rod 34 is moved. When the connecting rod 34 moves, it will cause the clamping block 35 to rotate around the rotatable connection with the inner shell 31, while driving the compression spring 36 to stretch or tighten. When the outer shell is released, the clamping block 35 is reset by the tension or pulling force of the compression spring 36.

[0030] It should be noted that the connecting assembly 2 includes two opposing clamping plates 21 and a fastening rod 22;

[0031] Two clamping plates 21 are fixedly connected to one of the plate 1. A cylinder 23 is rotatably connected between the clamping plates 21. The cylinder 23 is fixedly connected to the other plate 1. First teeth 211 are provided on the opposite surfaces of the two clamping plates 21. Second teeth 231 that mesh with the first teeth 211 are provided at both ends of the cylinder 23. The clamping plates 21 are made of deformable materials such as plastic parts, so that the end of the circular plate 25 that is farther from the circular axis can rotate downward, thereby deforming and clamping the cylinder 23.

[0032] The fastening rod 22 passes through two clamping plates 21 and a cylinder 23. One end of the fastening rod 22 is threadedly connected to an abutment plate 24 that abuts against one of the clamping plates 21. The other end of the fastening rod 22 is rotatably connected to two circular plates 25. The two circular plates 25 are eccentrically positioned relative to the fastening rod 22. A handle 26 is fixedly connected between the two circular plates 25. The fastening rod 22 is rotatably connected to the two circular plates 25 via a circular shaft. Rotating the abutment plate 24 causes the end of the circular plate 25 closer to the circular shaft to contact the clamping plate 21. Because the circular plate 25 is eccentrically positioned relative to the fastening rod 22, when the circular plate 25... When the end of the circular plate 25 closer to the circular shaft contacts the clamping plate 21, the end of the circular plate 25 farther from the circular shaft is rotated down by rotating it, so that it can come into contact with the clamping plate 21 and clamp the clamping plate 21 inward, engaging the first tooth 211 and the second tooth 231, thereby achieving the positioning effect. When it is necessary to change the angle between the two plates 1, the end of the circular plate 25 closer to the circular shaft is rotated down by the handle 26, so that the force of clamping the clamping plate 21 inward is canceled, and the first tooth 211 and the second tooth 231 no longer engage, thereby changing the angle between the two plates 1. After the change is completed, the above operation can be repeated.

[0033] The plate 1 has an L-shaped channel 11 in the middle, and the adjustment component 4 includes an L-shaped plate 41 slidably connected in the L-shaped channel 11. One end of the L-shaped plate 41 has a third tooth 42. A U-shaped plate 43 is fixedly connected to the upper end of the L-shaped plate 41, and a limit wheel 44 is rotatably connected in the U-shaped plate 43.

[0034] Furthermore, the positioning component 5 includes a rack 51 slidably connected within the L-shaped channel 11. A guide rod 52, which passes through the plate 1, is fixedly connected to the rack 51. A groove 13 is formed on the plate 1. A connecting plate 53 is fixedly connected to the other end of the guide rod 52. A spring 54 is sleeved on the guide rod 52. The spring 54 is fixedly connected to both the connecting plate 53 and the plate 1. The connecting plate 53 can be embedded in the groove 13. By moving the L-shaped plate 41, the U-shaped plate 43 is moved, thereby changing the curvature of the optical cable bend. When it moves to the corresponding position... When in position, push the connecting plate 53 into the groove 13, and the rack 51 engages with the third tooth 42 to position the adjusting component 4. The locking rod 62 locks the connecting plate 53 in place, preventing it from springing back due to the tension of the spring 54. When it is necessary to adjust the bending angle of the optical cable, pull the locking rod 62 open, and the connecting plate 53 pops out due to the tension of the spring 54. At the same time, the rack 51 moves backward and is no longer engaged with the third tooth 42, thus adjusting the position of the adjusting component 4 and changing the bending angle of the optical cable. After adjustment, push the connecting plate 53 back into the groove 13 to position it.

[0035] Based on the above embodiments, the locking assembly 6 includes a locking block 61 fixedly connected to the plate 1. A locking rod 62 is provided on the locking block 61. A tension spring 63 is fixedly connected between the locking rod 62 and the locking block 61. The locking rod 62 has a chamfer on the outward side, so the connecting plate 53 can be pushed in directly. When the connecting plate 53 enters the groove 13, the locking rod 62 will be reset by the tension spring 63 and abut against and fix the connecting plate 53.

[0036] Working method: During operation, the outer shell 32 is rotated, driving the connecting rod 34 to move. When the connecting rod 34 moves, it will cause the clamping block 35 to rotate inward around the connection point with the inner shell 31, thus facilitating the insertion of the optical cable. After the optical cable is inserted, it is locked in the limit wheel 44. Then, the outer shell 32 is released. Because the clamping block 35 rotates at the same time, it drives the compression spring 36 to tighten. Therefore, the clamping block 35 will reset and clamp the optical cable through the tension of the compression spring 36. Then, the position of the adjusting component 4 is adjusted according to the required bending arc. After adjustment, the connecting plate 53 is pushed into the groove 13. The locking rod 62 is reset by the tension spring 63 and abuts and fixes the connecting plate 53. At the same time, the rack 51 engages with the third tooth 42 to position the adjusting component 4. Then, the two plates 1 are rotated to adjust the bending angle. After adjustment, After completion, rotate the section of the circular plate 25 that is farther from the circular axis down, so that the clamping plate 21 clamps inward, engaging the first tooth 211 with the second tooth 231 to achieve the positioning effect. When the curvature needs to be adjusted, pull out the locking rod 62, and the connecting plate 53 pops out under the tension of the spring 54. At the same time, the rack 51 moves backward and no longer engages with the third tooth 42, so the position of the adjusting component 4 can be adjusted. After the adjustment is completed, push the connecting plate 53 back in. When the angle needs to be adjusted, rotate the end of the circular plate 25 that is closer to the circular axis down using the handle 26, so that the force of the clamping plate 21 clamping inward is canceled, and the first tooth 211 and the second tooth 231 no longer engage, so the angle between the two plates 1 can be changed. After completion, rotate the end of the circular plate 25 that is farther from the circular axis down using the handle 26.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
