[0026] Please see Figures 1-5 This utility model provides a technical solution: a wiring device for power engineering, including a junction box body 1, a main fixing structure 7, and a sub-fixing structure 8. Wire pipes 3 are provided on both sides of the junction box body 1. An inner cavity is opened at the top of the junction box body 1. A wiring port 6 is opened at the connection between the wire pipes 3 and the inner cavity of the junction box body 1. A box cover 2 is provided at the top opening of the junction box body 1. The main fixing structure 7 is provided at the bottom center of the inner cavity of the junction box body 1. The main fixing structure 7 includes a first fixing block 9 and a second fixing block 10. The bottom of the second fixing block 10 is connected to the bottom of the junction box body 1. A fixing groove 11 is provided through the top center of the second fixing block 10. First ear plates 12 are provided on both sides of the top of the second fixing block 10. The first fixing block 9 is provided above the second fixing block 10.

[0027] The bottom of the junction box body 1 is provided with two separate fixing structures 8. The two separate fixing structures 8 include a base 23 and a clamping plate 27. The bottom of the base 23 is connected to the bottom of the inner cavity of the junction box body 1. A sliding inner cavity 24 is longitudinally opened at the top center of the junction box body 1. Threaded rods 25 are provided at both ends of the sliding inner cavity 24. Sliding blocks 26 are slidably connected to both ends of the sliding inner cavity 24. Threaded holes are provided through the center of both ends of the sliding blocks 26. The threaded holes are located on the surface of the threaded rods 25. The top of the sliding blocks 26 is connected to the bottom center of the clamping plate 27.
[0028] Furthermore, a fixing sleeve 5 is provided at the four corners of the bottom of the inner cavity of the junction box body 1, and a third through hole is provided at the four corners of the box cover 2. A fixing bolt 4 is provided inside the fixing sleeve 5, and the top of the surface of the fixing bolt 4 is located at the third through hole.
[0029] Specifically, this utility model uses fixing bolts 4 to fix the junction box body 1 and the box cover 2.
[0030] Furthermore, the top two ends of the second fixing block 10 are provided with slots 13, which are engaged with the locking blocks. The two locking blocks are located at the bottom two ends of the first fixing block 9.
[0031] Furthermore, a second through hole 16 is provided through the center of the first ear plate 12, and a second ear plate 14 is provided on both sides of the bottom of the first fixing block 9. A first through hole 15 is provided through the center of the second ear plate 14, and the first through hole 15 and the second through hole 16 are connected by fastening bolts.
[0032] Specifically, when the wire needs to be placed into the fixing slot 11, firstly, align the locking block at the first fixing block 10 with the locking slot 13 to make a snap-fit connection between the first fixing block 10 and the second fixing block 11. Then, insert fastening bolts into the first through hole 15 and the second through hole 16 to fix the first fixing block 10 and the second fixing block 11 again. Finally, lift the pressure plate 20 upward. During the upward lifting of the pressure plate 20, the connecting rod 19 will also move upward. The upward movement of the moving rod 19 will cause the fixing plate 18 to move upward. After the fixing plate 18 is moved to the same horizontal plane as the top of the wire, stop lifting the pressure plate 20 upward.
[0033] It should be noted that the pressure plate 20 is limited by two limiting rods 21 to prevent the pressure plate 20 from shifting during movement.
[0034] Furthermore, the top front and back of the first fixing block 9 are provided with limiting rods 21, the top of the limiting rods 21 are connected to the bottom center of the limiting plate 22, and the two limiting rods 21 pass through the pressure plate 20.
[0035] Furthermore, a protruding block 28 is provided at the center of the front of the base 23. One end of the threaded rod 25 is connected to the rotating shaft 31, and the other end of the rotating shaft 31 is connected to the first bevel gear 32. The rotating shaft 31 is located inside the base 23, and the first bevel gear 32 is located in the inner cavity of the protruding block 28. The first bevel gear 32 is meshed with a second bevel gear 33. A rotating rod 29 is provided at the top of the second bevel gear 33. The other end of the rotating rod 29 passes through the top of the protruding block 28 and is located above the protruding block 28. A handwheel 30 is provided at the other end of the rotating rod 29.
[0036] Furthermore, the surface of the threaded rod 25 is provided with a first thread and a second thread. One end of the first thread is located at one end of the threaded rod 25, and the other end of the first thread is located at the center of the threaded rod 25. One end of the second thread is located at the other end of the threaded rod 25, and the other end of the second thread is located at the center of the threaded rod 25. The first thread and the second thread have different rotation directions.
[0037] Specifically, when the distance between the two clamping plates 27 is greater than the diameter of the wire, the operator can rotate the handwheel 30 for adjustment. The rotation of the handwheel 30 will cause the rotating rod 29 to rotate, which in turn will cause the second bevel gear 33 to rotate. The rotation of the second bevel gear 33 will cause the first bevel gear 32 to rotate, which will cause the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 will cause the threaded rod 25 to rotate, which will cause the two clamping plates 27 to move toward the middle of the sliding inner cavity 24.
[0038] It should be noted that, as mentioned above, the threads at both ends of the threaded rod 25 rotate in different directions. When the threaded rod 25 rotates, the different threads at both ends will cause the sliding block 26 to move in different directions, which will cause the clamping plate 27 to move towards the middle of the sliding inner cavity 24.
[0039] Working principle: When in use, the operator inserts the wire into one of the conduits 3. At this time, the wire will enter the inner cavity of the junction box body 1 from the connection port 6. Then, the wire is placed in the fixing slot 11 of the main fixing structure 7 and fixed by the main fixing structure 7. After the fixing is completed, the other end of the wire is passed out from the other connection port 6. Finally, the wire will pass out from the conduit 3.
[0040] After the wires are threaded through, check whether the clamps 27 of the fixing structure 8 at different directions are tightly connected to both sides of the wires. If not, the operator rotates the handwheel 30 to make the clamps 27 tightly connected to both sides of the wires. Otherwise, cover the top of the junction box body 1 with the box cover 2, and then insert fixing bolts 4 into the four third through holes to fix the junction box body 1 to the box cover 2.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
