Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a lead wire device for power distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are suitable for situations where the load is relatively dispersed and there are few circuits; motor control centers are used for situations where the load is concentrated and there are many circuits. They distribute the electrical energy of a circuit from the previous level of power distribution equipment to the nearest load. This equipment should provide protection, monitoring, and control for the load.

[0003] The announcement number CN221597052U discloses a lead wire device for a power distribution cabinet, including a cabinet and multiple wire retainers. Multiple wire holes are opened on the back of the cabinet, and the multiple wire retainers are respectively located inside the multiple wire holes and are threadedly connected to each other. Multiple sealing gaskets are fixedly connected inside the multiple wire retainers.

[0004] In the aforementioned patent, the transfer drum and the steering seat are kept perpendicular. Right-angle bends can cause stress concentration in the cable at the bend, which can easily lead to insulation damage or cable breakage with long-term use, thereby increasing the risk of failure. Therefore, this application provides a lead wire for a distribution cabinet to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lead wire for a distribution cabinet to solve the problem mentioned in the background art that the cable reel and the turntable are kept perpendicular, and the right-angle bend will cause stress concentration in the cable at the bend, which will easily cause insulation layer damage or cable breakage after long-term use, thereby increasing the risk of failure.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A lead wire for a power distribution cabinet includes a mounting cylinder and a rotating base that are rotatably connected. The rotating base is rotatably connected to the rotating cylinder. Two mounting slots symmetrically formed on the rotating base are provided. The rotating cylinder is provided with a mounting slot corresponding to the mounting slots 1. A limiting block movably passes through the interior of the mounting slot 2. The limiting block passes through the interior of the mounting slot 1. A limiting plate is fixedly installed at one end of the limiting block. One side of the limiting plate is in contact with the inner wall of the rotating cylinder. A threaded rod is fixedly installed on the other side of the limiting block. A threaded seat is threadedly connected to the outer wall of the threaded rod.

[0008] Preferably, a hexagonal bolt is fixedly installed on one side of the threaded seat.

[0009] Preferably, a protective pad is fixedly installed on one side of the hexagonal bolt.

[0010] Preferably, a rubber pad is fixedly installed on one side of the rotating seat, the rubber pad is disposed on one side of the mounting groove, and one side of the rubber pad is in contact with one side of the protective pad.

[0011] Preferably, two elastic plates are fixedly installed inside the rotating cylinder, and a fixing plate is fixedly installed on one side of each elastic plate.

[0012] Preferably, two elastic plates are fixedly installed at the bottom of the rotating seat, and two rotating grooves are opened at the top of the mounting cylinder, with the elastic plates passing through the interior of the rotating grooves.

[0013] Preferably, a rubber sheet is fixedly installed on one side of the elastic sheet, and one side of the rubber sheet is in contact with one side of the rotating groove.

[0014] Preferably, a plurality of sealing rings are fixedly installed inside the mounting cylinder.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting limit blocks, the angles of the rotating cylinder and the rotating seat can be adjusted and fixed. The cable routing can be adjusted according to actual needs, making the wiring more flexible and adaptable to different installation environments and spatial layouts. This avoids excessive stress on the cable at bends, reduces the risk of cable damage and breakage, thereby extending the cable's service life, and avoids local overheating caused by fixed angles, thus improving the system's reliability.

[0017] By setting an elastic piece that passes through the interior of the rotating groove, after pinching and rotating the elastic piece, and then releasing the force applied to the elastic piece, the elastic piece rebounds, causing one side of the rubber sheet to abut against the edge of the rotating groove, thereby fixing the position of the elastic piece and thus fixing the relative position of the rotating seat and the mounting cylinder.

[0029] like Figure 1-4As shown, an embodiment of this utility model provides a lead wire for a power distribution cabinet, including a mounting cylinder 1 and a rotating seat 2 rotatably connected. A rotating cylinder 3 is rotatably connected inside the rotating seat 2. Two mounting slots 4 are symmetrically opened on the rotating seat 2. A mounting slot 5 corresponding to the mounting slots 4 is opened on the rotating cylinder 3. A limiting block 6 moves through the interior of the mounting slot 4. A limiting plate 7 is fixedly installed at one end of the limiting block 6. One side of the limiting plate 7 is in contact with the inner wall of the rotating cylinder 3. A threaded rod 8 is fixedly installed on the other side of the limiting block 6. A threaded seat 9 is threadedly connected to the outer wall of the threaded rod 8.

[0030] When using this device, the side of the mounting cylinder 1 away from the rotating seat 2 is fixedly installed on the distribution cabinet. Then, the angle between the rotating seat 2 and the rotating cylinder 3 is adjusted according to the direction of the cable routing. Next, the limiting plate 7 passes through the inside of the second mounting groove 5 and then through the inside of the first mounting groove 4. One side of the limiting plate 7 contacts the inner wall of the rotating cylinder 3. At this time, the limiting block 6 penetrates the inside of the first mounting groove 4 and the second mounting groove 5. Then, the rotating threaded seat 9 is fixed on the threaded rod 8, thereby fixing the rotating seat 2 and the rotating cylinder 3. By setting the limiting block 6, the angle between the rotating cylinder 3 and the rotating seat 2 can be adjusted and fixed. The cable routing can be adjusted according to actual needs, making the wiring more flexible and adaptable to different installation environments and spatial layouts. This avoids excessive stress on the cable at bends, reduces the risk of cable damage and breakage, and extends the service life of the cable. It also avoids local overheating caused by fixed angles and improves the reliability of the system.

[0031] like Figure 1-4 As shown, a hexagonal bolt 10 is fixedly installed on one side of the threaded seat 9, which facilitates the operation of rotating the threaded seat 9 by clamping the outer wall of the hexagonal bolt 10 with a tool.

[0032] like Figure 1-4 As shown, a protective pad 11 is fixedly installed on one side of the hexagonal bolt 10. The protective pad 11 protects one side of the threaded seat 9 to prevent excessive rotation of the threaded seat 9 from causing wear between the hexagonal bolt 10 and the rotating seat 2.

[0033] like Figure 2-4 As shown, a rubber pad 12 is fixedly installed on one side of the rotating seat 2. The rubber pad 12 is located on one side of the mounting groove 4. One side of the rubber pad 12 is in contact with one side of the protective pad 11, which increases the friction between the protective pad 11 and the rotating seat 2, thereby fixing the angular position of the protective pad 11.

[0034] like Figure 2As shown, two elastic plates 17 are fixedly installed inside the rotating cylinder 3. A fixing plate 18 is fixedly installed on one side of the elastic plate 17. During the cable laying process, the cable passes through the mounting cylinder 1, the rotating seat 2 and the rotating cylinder 3. When passing through the inside of the rotating cylinder 3, the outer wall of the cable squeezes the fixing plate 18, causing the fixing plate 18 to approach the inner wall of the rotating cylinder 3, and the elastic plate 17 deforms accordingly.

[0035] like Figure 1-4 As shown, two elastic plates 13 are fixedly installed at the bottom of the rotating seat 2, and two rotating grooves 15 are opened at the top of the mounting cylinder 1. The elastic plates 13 pass through the interior of the rotating grooves 15. When adjusting the relative angle between the mounting cylinder 1 and the rotating seat 2, the elastic plates 13 are manually pinched and then rotated so that the rotating seat 2 rotates on one side of the mounting cylinder 1, and the elastic plates 13 rotate inside the rotating grooves 15.

[0036] like Figure 1-4 As shown, a rubber sheet 14 is fixedly installed on one side of the elastic sheet 13. One side of the rubber sheet 14 is in contact with one side of the rotating groove 15. After the force applied to the elastic sheet 13 is released, the elastic sheet 13 rebounds, causing one side of the rubber sheet 14 to abut against the edge of the rotating groove 15, thereby fixing the position of the elastic sheet 13 and thus fixing the relative position of the rotating seat 2 and the mounting cylinder 1.

[0037] like Figure 1 As shown, multiple sealing rings 16 are fixedly installed inside the mounting cylinder 1, which are in close contact with the outer wall of the cable.

[0038] The technical solution provided by this utility model involves fixing the side of the mounting cylinder 1 away from the rotating seat 2 to the distribution cabinet. Then, the angle between the rotating seat 2 and the rotating cylinder 3 is adjusted according to the direction of the cable routing. Next, the limiting plate 7 passes through the interior of the second mounting groove 5, and then through the interior of the first mounting groove 4. One side of the limiting plate 7 contacts the inner wall of the rotating cylinder 3. At this point, the limiting block 6 penetrates the interior of the first mounting groove 4 and the second mounting groove 5. Then, the rotating threaded seat 9 is fixed to the threaded rod 8, thereby fixing the rotating seat 2 and the rotating cylinder 3. The angle between the mounting cylinder 1 and the rotating seat 2 is adjusted accordingly. At the correct angle, manually pinch the elastic sheet 13 and then rotate it so that the rotating seat 2 rotates on one side of the mounting cylinder 1. The elastic sheet 13 rotates inside the rotating groove 15. After releasing the force applied to the elastic sheet 13, the elastic sheet 13 rebounds, causing one side of the rubber sheet 14 to abut against the edge of the rotating groove 15, thereby fixing the position of the elastic sheet 13. During the cable laying process, the cable passes through the mounting cylinder 1, the rotating seat 2 and the rotating cylinder 3. When passing through the inside of the rotating cylinder 3, the outer wall of the cable presses against the fixing plate 18, causing the fixing plate 18 to approach the inner wall of the rotating cylinder 3, and the elastic sheet 17 deforms accordingly.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
