Description

Technical Field

[0001] This utility model relates to the field of conductor frame technology, and in particular to a conductor frame that is easy to adjust. Background Technology

[0002] A conductor support frame is a device used to support and fix conductors, mainly used in power and communication engineering. Its primary function is to ensure the stability of cables during laying and construction, preventing twisting, wear, or breakage. It also helps ensure the smoothness of laying and construction operations, improving cable safety. Most conventional conductor supports consist of a combination of components such as a fixing frame, a positioning frame, conductor rollers, and a mounting frame, as shown in the attached diagram. Figure 5 As shown, the cable can be transmitted by mounting it on a rack or wall using a mounting bracket and passing it between two conductor rollers.

[0003] In typical cable tray structures, spacing adjustments are required to ensure smooth transmission of cables of different diameters. Conventional cable tray adjustments involve loosening the nuts, adjusting the spacing by sliding the tray, and then tightening the nuts to secure it against the positioning frame. This method is time-consuming, labor-intensive, and inconvenient. Furthermore, the stability of the adjusted positioning is compromised. With cable tension, the tightened nuts are prone to slippage, causing displacement of the cable tray rollers and resulting in insufficient stability during use. Utility Model Content

[0028] Reference Figure 1-4 This utility model provides an embodiment of an adjustable guide frame, including a fixed frame 1, a positioning frame 2 fixedly connected to the fixed frame 1, a movable plate 3 on the outer side of the positioning frame 2, and guide rollers 4 rotatably connected to the movable plate 3. Two guide rollers 4 are provided. An adjusting groove 5 is provided on the positioning frame 2, and a threaded rod 6 is rotatably connected within the adjusting groove 5. An adjusting block 7 is threadedly fitted onto the threaded rod 6. The threaded rod 6 is positioned and installed at its contact point with the inner wall of the adjusting groove 5 via a bearing. The adjusting block 7 and the adjusting groove 5 are nested and slidingly fitted. The adjusting block 7 is fixedly connected to the movable plate 3. Two sets of structures are correspondingly provided for the movable plate 3, the guide rollers 4, and the adjusting groove 5 and adjusting block 7 on the positioning frame 2. The thread directions on both sides of the threaded rod 6 are reversed. The reverse threads on both sides of the segment 7 and the threaded rod 6 are connected by corresponding threads. The fixed frame 1 is equipped with an operating mechanism. When the threaded rod 6 is rotated by the operating mechanism, the two adjusting blocks 7 can be moved closer or further apart. This can drive the two moving plates 3 to adjust the spacing, thereby driving the two guide rollers 4 to adjust the spacing to meet the needs of cables of different diameters for cable work. The top of the fixed frame 1 is fixedly connected to the mounting frame 20. The mounting frame 20 is provided with mounting holes 21. The mounting frame 20 is L-shaped. Bolts can be passed through the mounting holes 21 and tightened to fix it to the frame or wall. The structure can be installed horizontally to conduct cables or vertically to conduct cables at turning positions. This completes the fixed installation of the entire guide frame and facilitates the positioning of the guide wire.

[0029] The operating mechanism includes an internal groove 8 set in the fixed frame 1. A driven gear 9 is nested and fixedly connected to the outer surface of the threaded rod 6 within the internal groove 8. A driving gear 10 is rotatably connected within the internal groove 8. The central shaft of the driving gear 10 is positioned and installed at the contact point with the inner wall of the internal groove 8 via a bearing. The driving gear 10 and the driven gear 9 are meshed. A fixed disk 11 is fixedly connected to the outer surface of the fixed frame 1. A fixed groove 12 is provided on the fixed disk 11. A rotating wheel 13 is fixedly connected to one end of the central shaft of the driving gear 10 within the fixed groove 12. A rotating block 14 is fixedly connected to the rotating wheel 13. The outer surface of the guide roller 14 is provided with anti-slip textured surfaces. A fixing mechanism is provided between the fixed plate 11 and the rotating wheel 13. The positioning frame 2, the moving plate 3, the threaded rod 6, the adjusting block 7, and the driven gear 9 are arranged in two sets and are located at the two ends of the guide roller 4. Both driven gears 9 are meshed with the driving gear 10. During operation, rotating the rotating block 14 drives the rotating wheel 13 to rotate, the rotating wheel 13 drives the driving gear 10 to rotate, and the driving gear 10 drives the two driven gears 9 to rotate synchronously. The two driven gears 9 can then drive the two threaded rods 6 to rotate, thus achieving stable adjustment of the guide roller 4.

[0030] The fixing mechanism includes a threaded groove 15 on the fixed plate 11 and a limiting groove 19 on the rotating wheel 13. A threaded post 16 is threadedly connected to the threaded groove 15. A rotating block 17 is fixedly connected to the top of the threaded post 16, which is located outside the fixed plate 11. A limiting post 18 is fixedly connected to the bottom of the threaded post 16. The limiting post 18 and the limiting groove 19 are connected by a plug-in fit. Multiple limiting grooves 19 are provided and evenly distributed on the outer surface of the rotating wheel 13. The multiple limiting grooves 19 are arranged in a ring on the surface of the rotating wheel 13. During operation, the rotating block 17 is rotated, and the rotating block 17 drives the threaded post 16 to screw into the threaded groove 15. After screwing in, the threaded post 16 drives the limiting post 18 to insert into the corresponding limiting groove 19, thus completing the fixing work of the fixing mechanism. This locks the rotating wheel 13, preventing it from rotating on its own, thereby achieving stable positioning of the guide roller 4 and preventing displacement.

[0031] Working principle: When using the easily adjustable guide frame, rotating block 14 drives rotating wheel 13 to rotate, rotating wheel 13 drives driving gear 10 to rotate, driving gear 10 drives two driven gears 9 to rotate synchronously, and the two driven gears 9 drive two threaded rods 6 to rotate. The threaded rods 6 drive two adjusting blocks 7 to move closer or further apart, which drives two moving plates 3 to move. The two moving plates 3 drive two guide rollers 4 to adjust the distance, thus completing the adjustment of guide rollers 4. After adjustment, the guide rollers 4 are fixed by a fixing mechanism to lock them in place, preventing them from shifting on their own.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
