Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically, to an adjustable cast busbar trough. Background Technology

[0002] In the existing technology, the space adjustment of conductor slots in an adjustable cast-in-place busbar trunking is inconvenient and difficult to adapt to different types of conductors. The conductor slot positions of traditional busbar trunking are mostly fixed or have limited adjustment range, making it impossible to flexibly adjust the longitudinal position according to the needs of different specifications and quantities of conductors. This results in poor adaptability in actual installation and use, making it difficult to meet diverse electrical configuration requirements.

[0003] Existing adjustment mechanisms typically require disassembling busbar trunking components or using specialized tools to adjust conductor positions. This process is complex, time-consuming, and labor-intensive, increasing installation and maintenance workload and reducing construction efficiency. Traditional fixing methods often employ simple bolt fastening or snap-fit ​​connections, which are prone to loosening due to vibration, thermal expansion and contraction during long-term use, failing to provide a durable and stable position lock and posing safety hazards. Existing busbar trunking lacks auxiliary stabilization mechanisms, making it easy for the adjusted conductor position to unexpectedly shift or deflect, especially when carrying high currents or subjected to external impacts, making it difficult to maintain the conductor's precise positioning and stability.

[0022] In this embodiment, the adjusting block 2 is longitudinally slidably disposed within the conductor groove 4 of the busbar unit 1. The guide rod 3 installed at one end of the adjusting block 2 slides longitudinally on the busbar unit 1 in cooperation with it. By the longitudinal movement of the adjusting block 2 and the guide rod 3, the longitudinal position of the conductor inside the busbar unit 1 can be adjusted, realizing flexible adjustment of the spatial layout. The guide rod 3 extends into the adjusting sleeve 5 rotatably installed on the end face of the busbar unit 1. By rotating the adjusting sleeve 5, the adjusting sleeve 5 drives the guide rod 3 to move longitudinally on the busbar unit 1 through the spiral groove 8 structure, thereby driving the adjusting block 2 to move to the target position. The longitudinal sliding sleeve 7 is longitudinally slidably installed on the outer wall of the adjusting sleeve 5. The inner wall of the longitudinal sliding sleeve 7 presses against multiple sets of anti-tension spring rods 6, so that the anti-tension spring rods 6 are embedded in the spiral groove 8 on the outer wall of the guide rod 3 to form a mechanical lock, fixing the longitudinal position of the guide rod 3 and the adjusting block 2. When adjustment is required, the longitudinal sliding sleeve 7 is moved to release the pressure, and the anti-tension spring rods 6 are disengaged from the spiral groove 8 to release the lock.

[0026] More specifically, multiple sets of parallel conductor grooves 4 are opened on the busbar unit 1. Adjusting blocks 2 are slidably installed in each set of conductor grooves 4. The guide rods 3 on the adjusting blocks 2 extend into the corresponding adjusting sleeves 5. Rotating the adjusting sleeves 5 drives the guide rods 3 and adjusting blocks 2 to move longitudinally in the conductor grooves 4 through the spiral groove structure 8, adjusting the longitudinal spatial position of the conductors inside the busbar. After adjusting to the target position, the longitudinal sliding sleeve 7 slides longitudinally along the adjusting sleeve 5. The pressure grooves 15 on the inner wall of the longitudinal sliding sleeve 7 press against the spirally distributed anti-tension spring rods 6 on the outer wall of the adjusting sleeve 5, so that the anti-tension spring rods 6 are embedded in the spiral grooves 8 of the guide rods 3. A mechanical lock is formed, fixing the positions of the adjusting block 2 and the guide rod 3. The guide block 9 slides and guides within the guide groove 11. The bidirectional spring rod 10 is embedded step by step into the positioning hole 13 to achieve precise positioning of the longitudinal sleeve 7. The end face of the longitudinal sleeve 7 contacts the limiting plate 14 to provide a limit, ensuring stable movement and locking. The rotation limiting plate 12 is rotatably installed on the end face of the busbar unit 1 to ensure stable rotation of the adjusting sleeve 5.

When adjustment is required again, the longitudinal sleeve 7 is moved to release the pressure, the anti-tension spring rod 6 exits the spiral groove 8, and the adjusting sleeve 5 is rotated again to adjust the spatial position.

[0027] In summary, when the overall equipment is in use or operation: when the space adjustment mechanism is required to operate, the adjustment block 2 is longitudinally slidably set in the conductor groove 4 of the busbar unit 1, and the guide rod 3 installed at one end of the adjustment block 2 slides longitudinally on the busbar unit 1 in cooperation. Through the longitudinal movement of the adjustment block 2 and the guide rod 3, the longitudinal position of the conductor inside the busbar unit 1 can be adjusted, so as to realize the flexible adjustment of the spatial layout.

[0028] When the position fixing mechanism is in operation, the guide rod 3 extends into the adjusting sleeve 5, which is rotatably installed on the end face of the busbar unit 1. Rotating the adjusting sleeve 5 causes the guide rod 3 to move longitudinally on the busbar unit 1 through the spiral groove 8 structure, thereby driving the adjusting block 2 to move to the target position. The longitudinal sliding sleeve 7 is longitudinally slidably installed on the outer wall of the adjusting sleeve 5. The inner wall of the longitudinal sliding sleeve 7 presses against multiple sets of anti-tension spring rods 6, causing the anti-tension spring rods 6 to embed into the spiral groove 8 on the outer wall of the guide rod 3 to form a mechanical lock, fixing the longitudinal position of the guide rod 3 and the adjusting block 2. When adjustment is required, the longitudinal sliding sleeve 7 is moved to release the pressure, and the anti-tension spring rods 6 exit the spiral groove 8 to release the lock.

[0029] When the auxiliary mechanism needs to be stabilized, multiple sets of guide blocks 9 are installed on the end face of the longitudinal sleeve 7 and slide longitudinally within the guide groove 11 on the outer wall of the adjusting sleeve 5.

The guide rods 3 on the adjusting blocks 2 extend into the corresponding adjusting sleeves 5. Rotating the adjusting sleeves 5 drives the guide rods 3 and adjusting blocks 2 to move longitudinally in the conductor slots 4 through the spiral groove structure 8, adjusting the longitudinal spatial position of the conductors inside the busbar. After adjusting to the target position, the longitudinal sliding sleeve 7 slides longitudinally along the adjusting sleeve 5. The pressure groove 15 on the inner wall of the longitudinal sliding sleeve 7 presses against the spirally distributed anti-tension spring rods 6 on the outer wall of the adjusting sleeve 5, so that the anti-tension spring rods 6 are embedded in the spiral grooves 8 of the guide rods 3 to form Mechanical locking fixes the positions of adjusting block 2 and guide rod 3. Guide block 9 slides within guide groove 11 for guidance. Bidirectional spring rod 10 is embedded into positioning hole 13 in stages to achieve precise positioning of longitudinal sleeve 7. The end face of longitudinal sleeve 7 contacts limiting plate 14 to provide limit, ensuring stable movement and locking. Rotation limiting plate 12 is rotatably installed on the end face of busbar unit 1 to ensure stable rotation of adjusting sleeve 5. The busbar is fixed in the adjustment position and runs stably.
