[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0026] Figures 1-5 In one embodiment of this utility model, a cable layout structure for a transformer includes a mounting frame 1 and positioning seats 2 for cable fixing. The mounting frame 1 is provided with an adjustment mechanism 3 for adjusting the spacing between multiple sets of positioning seats 2, and the positioning seats 2 are provided with a positioning mechanism 4 for cable fixing. The adjustment mechanism 3 includes a mounting rod 301 fixedly mounted on the mounting frame 1. Two sets of symmetrically distributed first telescopic rods 302 are slidably mounted inside the mounting rod 301, and a second telescopic rod 303 is slidably mounted inside each of the two sets of first telescopic rods 302. Two sets of symmetrically distributed guide rails 304 are slidably mounted on the mounting frame 1, and the ends of the two sets of second telescopic rods 303 away from the mounting rod 301 are respectively fixedly connected to the two sets of guide rails 304. The adjustment mechanism 3 also includes multiple sets of adjustment frames 305 corresponding to the positioning seats 2, and the multiple sets of adjustment frames 305 are respectively fixedly connected to the corresponding positioning seats 2. The outer two sets of adjustment brackets 305 are fixedly connected to the two sets of guide rails 304, while the inner multiple sets of adjustment brackets 305 are slidably connected to the mounting bracket 1 and the guide rails 304. By setting adjustable-spacing positioning seats 2 and a linkage telescopic structure, the adaptability problem caused by the fixed spacing of traditional transformer cable supports is effectively solved. The adjustment mechanism 3 uses a bidirectional screw 306 to drive and cooperate with a multi-stage telescopic rod to achieve synchronous and symmetrical movement of the guide rails 304, ensuring linear and precise adjustment of the spacing of the multiple positioning seats 2. The cross-distributed connecting brackets form a stable parallelogram structure during telescopic movement, ensuring that the middle positioning seats 2 always maintain an equidistant distribution. Simultaneously, the positioning mechanism 4, through the design of a self-locking strap 404 using a coil spring 403, can quickly fix cables of different diameters. The elastic locking structure of the clamp 407 and the locking rod 405 allows for single-handed operation to lock the strap 404. This structure significantly improves the adaptability of cable layout, matching various cable arrangement requirements without replacing the bracket, reducing installation complexity and spare parts inventory costs, and is particularly suitable for transformer maintenance scenarios requiring frequent adjustments to cable configurations.
[0027] In this embodiment, reference Figure 2 , Figure 3As shown, a bidirectional screw 306 is rotatably mounted inside the mounting rod 301. A screw tube 308 is rotatably mounted inside each of the two sets of first telescopic rods 302. A first bevel gear 310 is sleeved on the bidirectional screw 306. A second bevel gear 311 is rotatably mounted inside the mounting rod 301, meshing with the first bevel gear 310. Two sets of symmetrically distributed sliding grooves 307 are provided on the bidirectional screw 306. Two sets of symmetrically distributed sliders 309 are provided inside each of the two sets of screw tubes 308. The sliders 309 and sliding grooves 307 are correspondingly arranged. The screw tubes 308 are slidably sleeved with the bidirectional screw 306 through the sliders 309 and sliding grooves 307. Both ends of 06 pass through two sets of first telescopic rods 302 and are threadedly connected to the two sets of first telescopic rods 302 respectively. Two sets of threaded tubes 308 pass through two corresponding sets of second telescopic rods 303 and are threadedly connected to the corresponding second telescopic rods 303 respectively. Two sets of cross-distributed first connecting frames 312 are provided between each pair of adjacent adjusting frames 305, and two sets of cross-distributed second connecting frames 313 are provided between each pair of adjacent adjusting frames 305. The right ends of the two sets of first connecting frames 312 are rotatably connected via a rotating shaft, and the left ends of the two sets of first connecting frames 312 are rotatably mounted with moving blocks 314, which are slidably connected to the corresponding adjusting frame 305. The left ends of the two sets of second connecting brackets 313 are rotatably connected via a rotating shaft, and the right ends of the two sets of second connecting brackets 313 are rotatably connected to the corresponding adjusting brackets 305 via a rotating shaft. When it is necessary to adjust the spacing of the cable positioning seats 2, the handle is rotated to rotate the second bevel gear 311 in conjunction with the first bevel gear 310 to drive the bidirectional screw 306 to rotate. By rotating the bidirectional screw 306, the two sets of first telescopic rods 302 are driven to move synchronously in opposite directions within the mounting rod 301. The reverse thread structure at both ends of the bidirectional screw 306 ensures the symmetrical movement of the first telescopic rods 302 on both sides. In conjunction with the sliding groove 307 and the slider 309, the screw tube 308 rotates synchronously with the bidirectional screw 306. The movement causes the two sets of second telescopic rods 303 to extend and retract synchronously within the first telescopic rod 302. The guide rails 304, which are fixedly connected to the ends of the second telescopic rods 303, slide accordingly, forming the first level of spacing adjustment. The adjustment frame 305 between adjacent positioning seats 2 forms a parallelogram linkage mechanism through the cross-distributed first connecting frame 312 and second connecting frame 313. When the guide rails 304 on both sides move, the moving block 314 on the first connecting frame 312 slides on the adjustment frame 305, driving the intermediate positioning seat 2 to move synchronously, ensuring that all positioning seats 2 remain evenly distributed during the adjustment process, and realizing the equidistant adjustment of multi-level positioning seats 2.
[0028] In this embodiment, reference Figure 4 and Figure 5As shown, the positioning mechanism 4 includes a storage box 401 fixedly installed on the positioning base 2. A winding rod 402 is rotatably installed inside the storage box 401. Two sets of symmetrically distributed coil springs 403 are sleeved on the winding rod 402. The inner and outer ends of the coil springs 403 are fixedly connected to the winding rod 402 and the storage box 401, respectively. A strap 404 is provided inside the storage box 401. The strap 404 is wound around the winding rod 402. A locking rod 405 is fixedly installed at the end of the strap 404 away from the winding rod 402. A fixing frame 406 is fixedly installed on the positioning base 2. Two sets of symmetrically distributed clamping rings 407 are sleeved on the fixing frame 406. The two sets of clamping rings 407 can be movably engaged with the locking rod 405. Two sets of symmetrically distributed torsion springs 408 are sleeved on the fixing frame 406. Both ends of 8 are fixedly connected to the corresponding clamping rings 407 and fixing brackets 406 respectively. When fixing the cable, the binding strap 404 is pulled out from the storage box 401 and wrapped around the cable. The coil spring 403 generates a rewinding force to automatically tighten the binding strap 404. The locking rod 405 at the end of the binding strap 404 is inserted into the clamping ring 407 of the fixing bracket 406. The clamping ring 407 locks the locking rod 405 under the action of the torsion spring 408. The elastic clamping force adapts to the fixing requirements of cables of different diameters, and the tension of the binding strap 404 can be automatically adjusted with the cable diameter. The entire system achieves stepless adjustment through mechanical linkage, which not only ensures the flexibility and accuracy of cable spacing adjustment, but also ensures the reliability and convenience of cable fixing. It is particularly suitable for transformer cable installation scenarios that require frequent layout adjustments.
[0029] In this embodiment, when the spacing of the cable positioning seats 2 needs to be adjusted, the second bevel gear 311 is rotated by rotating the handle, which in turn engages with the first bevel gear 310 to drive the bidirectional screw 306 to rotate. Rotating the bidirectional screw 306 drives the two sets of first telescopic rods 302 to move synchronously in opposite directions within the mounting rod 301. The reverse thread structure at both ends of the bidirectional screw 306 ensures the symmetrical movement of the first telescopic rods 302 on both sides. The sliding groove 307 and the slider 309 work together to make the screw tube 308 rotate synchronously with the bidirectional screw 306, thereby causing the two sets of second telescopic rods 303 to extend and retract synchronously within the first telescopic rods 302. The guide rails 304, fixedly connected to the ends of the second telescopic rods 303, slide accordingly, forming the first level of spacing adjustment. The adjustment frame 305 between adjacent positioning seats 2 forms a parallelogram linkage mechanism through the cross-distributed first connecting frame 312 and second connecting frame 313. When the guide rails 304 on both sides move... The moving block 314 on the first connecting frame 312 slides on the adjusting frame 305, driving the intermediate positioning seat 2 to move synchronously, ensuring that all positioning seats 2 are evenly distributed during the adjustment process, realizing the equidistant adjustment of multi-level positioning seats 2. When fixing the cable, the binding strap 404 is pulled out from the storage box 401 and wrapped around the cable. The coil spring 403 generates a back-winding force to automatically tighten the binding strap 404. The clamping rod 405 at the end of the binding strap 404 is inserted into the clamping ring 407 of the fixing frame 406. The clamping ring 407 locks the clamping rod 405 under the action of the torsion spring 408. The elastic clamping force adapts to the fixing requirements of cables of different diameters, and the tension of the binding strap 404 can be automatically adjusted with the cable diameter. The whole system achieves stepless adjustment through mechanical linkage, which not only ensures the flexibility and accuracy of cable spacing adjustment, but also ensures the reliability and convenience of cable fixing. It is particularly suitable for transformer cable installation scenarios that require frequent layout adjustments.
