Example

[0035] Please refer to Figures 1 to 6 As shown, the present invention provides a bus duct angle conversion connection structure, comprising two bus duct bodies 1, and a connection component is arranged between the two bus duct bodies 1;

[0036] The connection assembly includes a protective shell 3 and a connecting conductor 4 fixed inside the protective shell 3. The opposite ends of the bus trough body 1 are rotatably arranged on the inner wall of the protective shell 3. A plurality of groups of bus conductors 2 are penetrated and arranged inside the bus trough body 1. The number of connecting conductors 4 is the same as that of bus conductors 2, and both ends of the connecting conductor 4 are arc-shaped. The end of the bus conductor 2 located inside the protective shell 3 is also arc-shaped, and is slidingly fitted with the arc surface of the connecting conductor 4. The bus conductors 2 of the two bus trough bodies 1 are connected by the connecting conductor 4 of the protective shell 3. Both bus trough bodies 1 can be rotated relative to the protective shell 3 to achieve the purpose of adjusting the angle. When the bus trough body 1 rotates relative to the protective shell 3, the bus conductor 2 also rotates relative to the connecting conductor 4. Since the connection parts between the bus conductor 2 and the connecting conductor 4 are arc-shaped, the rotation of the bus conductor 2 relative to the connecting conductor 4 will not cause contact and disengagement;

The screw rod 14 is manually controlled to rotate so as to drive the adjusting plate 10 to move. The second guide groove 11 on the node plate 10 is displaced relative to the first guide groove 9 to change the position of the intersection thereof, thereby driving the positioning pin 7 to move along the first guide groove 9. The guide sleeve 8 reduces the friction resistance during the displacement of the positioning pin 7. The sliding of the positioning pin 7 relative to the first guide groove 9 realizes the rotation of the busbar trough body 1. The first guide groove 9 allows the busbar trough body 1 to rotate in an arc around the pin shaft 5 with the pin shaft 5 as the center. The adjusting plate 10 realizes the positioning of the positioning pin 7 through the adjustment control of the screw rod 14, thereby adjusting the rotation angle of the busbar trough body 1. One end of the screw rod 14 is fixed to The screw rod 14 is fixed on the outside of the decorative cover 12, and the adjusting plate 10 can be driven to slide by rotating the screw rod 14 to adjust the position of the busbar trough 1.

A reset spring 25 is connected between the bottom of the adjusting block 21 and the inner bottom of the assembly groove 20. A square groove 19 for accommodating the pressing block 18 is provided on the outer surface of the isolation block 17. The isolation block 17 takes the pin shaft 5 as the center of the circle to provide a stable supporting force to the connecting conductor 4, so that the connecting conductor 4 remains in a fixed position. The pressing block 18 can abut against the bus conductor 2 through the cooperation of the sliding rod 22 and the pushing plate 23 with the adjusting block 21 to achieve locking of the bus conductor 2. The adjusting block 21 slides up and down in the assembly groove 20. The design of the slope surface enables the pushing plate 23 to drive the sliding rod 22 when the adjusting block 21 moves, so that the pressing block 18 is pressed or released. The positioning spring 24 provides the reset and positioning function of the sliding rod 22 to ensure that the pressing block 18 is stable after being locked or released. The reset spring 25 resets after the adjusting block 21 is subjected to external force, so that the pressing block 18 returns to its original position, ensuring the stable operation of the locking assembly.

[0041] The isolation block 17 provides stable support for the connecting conductor 4, and at the same time, the busbar conductor 2 is locked by the pressing block 18 to ensure the firmness of the electrical connection. The adjustment block 21 cooperates with the slope surface, and the precise adjustment of the pressing block 18 is achieved through the slide bar 22 and the push plate 23 to ensure that the conductor can be reliably contacted or disengaged.

The overall design of the locking assembly ensures a stable connection between the conductors, and has flexible adjustment and reset functions, which improves the overall reliability of the device.

[0042] Specifically, Figure 2 and Figure 3As shown, the transmission assembly also includes a connecting rod 26 connected to the top of the adjustment block 21, the other end of the connecting rod 26 movably penetrates the isolation block 17 and the protective shell 3 is located inside the decorative cover 12, and the top of the connecting rod 26 on the same side is commonly connected with a fixing plate 27, and a screw 28 is vertically threaded through the middle outer wall of the fixing plate 27, and the screw 28 is rotatably set on the top of the protective shell 3, and the outer walls of both ends of the fixing plate 27 are vertically slidably provided with guide rods 29, and the guide rods 29 are connected to the top of the protective shell 3. The transmission assembly also includes a gear 30, a rack 31 and a sliding sleeve 32, the gear 30 is coaxially connected to the outer wall of the bottom end of the screw 28, and the rack 31 is slidably set on the top of the protective shell 3 and between the gear 30 The sliding sleeve 32 is meshed with each other, and the sliding sleeve 32 is movably sleeved on the outer surface of the screw rod 14 and axially slidably connected. A connecting frame 33 is connected between the sliding sleeve 32 and the rack 31, and the connecting frame 33 is located inside the decorative cover 12. The sliding sleeve 32 moves axially along the screw rod 14 and drives the rack 31 through the connecting frame 33. The rack 31 slides and drives the gear 30 meshing with it to rotate. The gear 30 rotates with the screw rod 28 to drive the fixed plate 27 to rise and fall. The fixed plate 27 is connected to the connecting rod 26, and the other end of the connecting rod 26 is connected to the adjusting block 21. Therefore, the lifting and lowering of the fixed plate 27 will drive the adjusting block 21 to move up and down through the connecting rod 26, thereby controlling the movement of the pressing block 18 inside the isolation block 17, thereby achieving the compression or release of the busbar conductor 2.

[0043] Through the meshing of the gear 30 and the rack 31, the transmission assembly can realize stable and precise up and down movement of the adjustment block 21, ensuring that the pressure block 18 can be effectively adjusted to achieve locking or loosening of the busbar conductor 2. The rotation of the screw 28 controls the transmission process, and the guide rod 29 ensures the stable sliding of the fixed plate 27, ensuring that the adjustment action is accurate and smooth. The various parts are closely connected and cooperated through the connecting rod 26, the sliding sleeve 32, etc., to achieve precise transmission of the pressure block 18 and the adjustment block 21, and ensure the overall reliability and operational flexibility of the cooperation between the transmission assembly and the locking assembly. The design of the transmission assembly ensures the coordinated operation of various components in the busbar system, realizes precise control of the pressure block 18, and is conducive to stable connection and adjustment between conductors;

[0045] When the transmission assembly drives the locking assembly to compress the bus conductor 2 and the connecting conductor 4, the transmission assembly will cover the steering assembly, so that in the compressed state, the operation of the transmission assembly closes or protects the steering assembly to prevent it from rotating during the compression period. When the transmission assembly drives the locking assembly to release the compression of the bus conductor 2 and the connecting conductor 4, the transmission assembly will make way to expose the steering assembly. At this time, the steering assembly can be operated freely to achieve the rotation adjustment of the bus trough body 1. This design makes the steering assembly locked when the conductors are compressed to avoid accidental rotation of the bus trough body 1 during the connection process, thereby ensuring the stability and safety of the operation. When the lock is released, the steering assembly is exposed again, allowing the bus trough body 1 to be rotated and adjusted, thereby improving the flexibility and controllability of the operation, ensuring the separation of the compression and rotation processes, and enabling the operation to have interlocking and unlocking functions in different states, thereby improving the safety of the equipment.

[0047] When the support spring 35 is in an uncompressed state, the protective tube 34 covers the hexagonal screw head 16, and the baffle 36 covers the hexagonal screw head 16 in an enclosed manner to prevent the hexagonal screw head 16 from being operated on by the outside. When the hexagonal screw head 16 needs to be operated, the protective tube 34 is pushed by the armrest 37, and the support spring 35 is compressed accordingly. The protective tube 34 moves inward to expose the hexagonal screw head 16, which is convenient for using tools for adjustment. After the adjustment is completed, the armrest 37 is released, the support spring 35 automatically resets, pushes the protective tube 34 back to its original position, and covers the hexagonal screw head 16 again to maintain the protective state.

[0049] Through the mutual cooperation of the transmission assembly and the steering assembly, when the locking assembly is driven to compress the conductor, the steering assembly is locked, thereby preventing the bus trough body 1 from accidentally rotating during the connection process, thereby ensuring the stability and safety of the operation. When the locking is released, the steering assembly is exposed again, allowing the bus trough body 1 to be rotated and adjusted, thereby improving the flexibility and controllability of the operation, ensuring the separation of the compression and rotation processes, and enabling the operation to have interlocking and unlocking functions in different states, thereby improving the safety and convenience of the device.
