Description

Technical Field

[0001] The utility model relates to the technical field of power grid wiring structures, and more specifically, it relates to a power grid wiring structure. Background Technique

[0002] In the existing technology, the power grid wiring structure is an important part of the power system, responsible for transmitting electrical energy from the power station to users. However, there are some problems in the existing power grid wiring structure during use, especially in terms of cable fixing. Since the existing structure cannot effectively fix the cables, this directly affects the use effect and reliability of the power grid.

[0003] First of all, the existing power grid wiring structure may lack an effective cable fixing mechanism. This may be due to deficiencies in structural design or limitations in fixing methods. For example, some wiring structures may only rely on simple clamps or straps for cable fixing, and this method may not provide sufficient stability and durability. This insufficient fixing may cause the cables to loosen, shift or fall off during use, thus affecting the normal operation of the power grid and the power transmission efficiency.

[0004] Secondly, the existing power grid wiring structure may not be able to adapt to different sizes and types of cables. Since there are various types of cables used in the power grid, including cables with different diameters and materials, the existing structure may not be able to adapt to these differences. This may lead to insecure cable fixing or incorrect installation, thereby affecting the reliability and safety of the power grid. In addition, insecure cable fixing may also cause the cables to be subjected to excessive stress or wear, shortening their service life and increasing maintenance and replacement costs.

[0016] (III) Advantageous Effects

[0017] Compared with the prior art, the present utility model provides a power grid wiring structure, which has the following advantageous effects:

[0018] 1. The design of the fixing mechanism enables the power grid wiring structure to effectively fix the cables. Through the cooperation of the connecting mechanism, the fixed sleeve, the shrinkage sleeve, the slider, the follower plate, the rotating tube, the conical sleeve, the limiting mechanism and the conical strip, the fixing mechanism can achieve the rapid fixing of the cables. By rotating the rotating tube, the conical sleeve can rotate, thereby driving the follower plate to slide along the inclined groove, causing the slider to move upward and contract along the axis, so that the fitting plate abuts against the cable, thus completing the fixing of the cable. This design not only simplifies the fixing steps, but also improves the fixing speed and accuracy, thereby improving the work efficiency and productivity.

[0019] 2. The design of the limit mechanism ensures the position stability of the fixing mechanism when fixing the cable. Through the cooperation of the middle ring and the limit ring, the limit mechanism can provide sufficient restraining force to maintain the stable state of the fixing mechanism. The functions of the middle ring and the limit ring enable the fixing mechanism to be firmly held in the fixing sleeve when fixing the cable, preventing the loosening or displacement of the fixing mechanism.

[0020] 3. The design of the connection mechanism enables the fixing mechanism to be firmly connected to the junction box. Through the cooperation of the threaded sleeve and the fitting sleeve, the connection mechanism can achieve a tight connection between the fixing mechanism and the junction box. The threaded sleeve is threadedly connected to the junction box, and the fitting sleeve abuts against the junction box, thus ensuring the stable and reliable connection between the fixing mechanism and the junction box.

[0031] In this embodiment, when it is necessary to fix the cable, first, by rotating the rotating tube 6, the tapered sleeve 7 can be driven to rotate. Since the limiting ring 14 and the threaded ring 15 are stuck on the intermediate ring 13, it can be ensured that the position of the tapered sleeve 7 is always engaged with the follower plate 5.

Therefore, when the rotating tube 6 is rotated, the conical bar 8 will always be engaged in the conical groove 9, and the oblique groove 10 and the shrinkage sleeve 3 are arranged in parallel, so the follower plate 5 can be driven to slide along the oblique groove 10, so that the slider 4 moves upward while shrinking along the axis, so that the bonding plate 12 is in contact with the cable, thereby completing the cable fixing process.

[0034] After the fixing of the plurality of fixing sleeves 2 is completed, the plurality of cables are then fixed, and the wiring process of the power grid cables is completed.
