[0001] This utility model relates to the field of power transmission and transformation engineering technology, and in particular to a cable fixing bracket for power transmission and transformation engineering. Background Technology

[0002] Power transmission and transformation projects are mainly used to construct power transmission paths from power plants to end users, ensuring the stable and efficient transmission of electrical energy. Cables are an important component of power transmission, and cable fixing brackets are required when installing and fixing cables.

[0003] Existing cable fixing brackets typically use bolts and nuts to secure and limit cables. However, this method is relatively cumbersome and complex, increasing the workload of workers and resulting in low overall fixing efficiency. Therefore, designing a cable fixing bracket for power transmission and transformation projects is a solution to this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cable fixing bracket for power transmission and transformation projects. In terms of usage, it is equipped with a limiting mechanism. By controlling the pressure plate to move to the left, and with the help of multiple limiting blocks, it can easily fix cables of different specifications and facilitate subsequent disassembly and device reset. It is also equipped with an anti-loosening mechanism, which uses a ring rubber pad in conjunction with a second spring to prevent the circular control block from loosening on its own.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable fixing bracket for power transmission and transformation projects includes a U-shaped fixing frame, with sliding grooves vertically formed at both the inner top and bottom of the U-shaped fixing frame; a limiting mechanism, comprising two guide rods, the left and right ends of which are fixedly connected to the inner walls of the corresponding sliding grooves on the left and right sides; multiple limiting blocks are provided in the middle of the U-shaped fixing frame, each limiting block being slidably connected to the two guide rods; limiting grooves are provided on opposite sides of every two cooperating limiting blocks; and two cooperating limiting blocks are elastically connected by two first springs; a rotating shaft is rotatably connected to the inner right side of the U-shaped fixing frame, the right end of which penetrates the inner right side of the U-shaped fixing frame and extends to the outside; a threaded groove is formed on the left side of the rotating shaft; a pressure plate is provided inside the U-shaped fixing frame, and a threaded rod is rotatably connected to the right side of the pressure plate; and an anti-loosening component to prevent the rotating shaft from becoming loose.

[0007] Preferably, the pressure plate is slidably connected to the two guide rods, and the threaded rod is threadedly connected to the threaded groove.

[0008] Preferably, the anti-loosening component includes a circular control block disposed on the right side of the rotating shaft, a rectangular inner groove is provided on the right side of the rotating shaft, a rectangular connecting block is fixedly connected to the left side of the circular control block, the left side of the rectangular connecting block is elastically connected to the left inner wall of the rectangular inner groove by a second spring, and an annular rubber pad is provided on the left side of the circular control block.

[0019] 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.

[0020] Reference Figures 1-3 A cable fixing bracket for power transmission and transformation engineering includes a U-shaped fixing bracket 1. The inner top and inner bottom of the U-shaped fixing bracket 1 are vertically provided with sliding grooves 2. The lower end of the U-shaped fixing bracket 1 is fixedly connected to a support rod 14. The lower end of the support rod 14 is fixedly connected to a mounting plate 15. The upper end of the mounting plate 15 is provided with multiple mounting holes 16.

[0021] The system also includes a limiting mechanism, which consists of two guide rods 3. The left and right ends of the two guide rods 3 are fixedly connected to the inner walls of the left and right sides of the corresponding sliding grooves 2. The middle part of the U-shaped fixing frame 1 is provided with multiple limiting blocks 4. Each limiting block 4 is slidably connected to the two guide rods 3. Each pair of cooperating limiting blocks 4 is provided with a limiting groove 5 on the opposite side. The limiting groove 5 can fix cables of different specifications and sizes. Each pair of cooperating limiting blocks 4 is elastically connected by two first springs 6. The first springs 6 can reset the limiting blocks 4 to the initial position when the cable is released, which is convenient for subsequent use. A rotating shaft 7 is rotatably connected to the inner wall of the right side of the U-shaped fixing frame 1. The right end of the rotating shaft 7 passes through the inner wall of the right side of the U-shaped fixing frame 1 and extends to the outside. A threaded groove is opened on the left side of the rotating shaft 7. A pressure plate 8 is provided inside the U-shaped fixing frame 1. The pressure plate 8 is slidably connected to the two guide rods 3. A threaded rod 9 is rotatably connected to the right side of the pressure plate 8. The threaded rod 9 is threadedly connected to the threaded groove.

[0022] The system also includes an anti-loosening component to prevent the rotating shaft 7 from becoming loose. The anti-loosening component includes a circular control block 10 located on the right side of the rotating shaft 7. A rectangular inner groove is provided on the right side of the rotating shaft 7. A rectangular connecting block 11 is fixedly connected to the left side of the circular control block 10. The rectangular connecting block 11 is slidably connected to the inner wall of the rectangular inner groove. The left side of the rectangular connecting block 11 is elastically connected to the left inner wall of the rectangular inner groove by a second spring 12. An annular rubber pad 13 is provided on the left side of the circular control block 10. The left side of the annular rubber pad 13 fits against the right side of the U-shaped fixing bracket 1, which can prevent the circular control block 10 from becoming loose during daily use.

[0023] In this invention, during use, the entire device is first fixed to a designated position using multiple bolts and mounting holes 16. Then, multiple cables to be fixed are passed through the gaps between two mating limit blocks 4 (only one cable is allowed to pass through between each pair of mating limit blocks 4). After all cables have passed through, the circular control block 10 is rotated, causing the rectangular connecting block 11 to rotate, which in turn causes the rotating shaft 7 to rotate. This causes the threaded rod 9 and the pressure plate 8 to move to the left simultaneously. When the pressure plate 8 moves to the left, it causes multiple limit blocks 4 to move, gradually reducing the gap between each pair of mating limit blocks 4 until the corresponding cable is completely clamped. At this time, multiple first springs 6 are compressed, thus fixing the cable. When disassembly is required, the pressure plate 8 can be moved to the right. At this time, due to the force of multiple first springs 6, the gap between each pair of mating limit blocks 4 gradually increases, thereby releasing the cable from the fixation. The entire fixing and disassembly process is convenient and quick, reducing the workload of the workers. It can also simultaneously fix cables of different specifications and sizes, making it highly adaptable.

[0024] It is worth mentioning that before each rotation of the circular control block 10, it is necessary to pull the circular control block 10 to the right so that the left side of the annular rubber pad 13 is disengaged from the contact with the ring-shaped fixing frame 1. At this time, the second spring 12 will be stretched. After the rotation is completed, the circular control block 10 is released. Due to the force of the second spring 12, the annular rubber pad 13 will automatically move to the left and fit against the right side of the ring-shaped fixing frame 1. In this way, by increasing the friction, the circular control block 10 can be prevented from loosening on its own, thereby improving the fixing effect of the entire device.

[0025] 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.
