[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a coaxial busbar flange structure, including a busbar trunking 1 and a flange 2. A steering member is provided at the top of the flange 2, and the steering member is used to drive the flange 2 to rotate. A rotating rod 8 is rotatably arranged inside the bottom end of the flange 2. A pressing plate 9 is slidably arranged on the outer wall of one end of the rotating rod 8. The rotating rod 8 drives the pressing plate 9 to move inward through a connecting rod 10. A connecting rod 10 is fixedly arranged at the other end of the rotating rod 8. The connecting rod 10 drives the rotating rod 8 to rotate through a push rod 11. A push rod 11 is rotatably arranged at the top end of the connecting rod 10. The push rod 11 is used to drive one end of the connecting rod 10 to rotate. A rotating tube 12 is slidably arranged on the outer wall of the push rod 11. The rotating tube 12 drives the push rod 11 to move back and forth through the thread provided on the inner wall. Threads are provided on the outer wall of the rotating rod 8, through holes are provided at the top end of the pressing plate 9, threads are provided in the through holes, reverse threads are provided on the outer wall of the push rod 11, and reverse threads matching the outer wall of the push rod 11 are provided on the inner wall of the rotating tube 12.

[0024] Specifically, the steering member includes a support block 3. The support block 3 is fixedly arranged at the top of the flange 2. The support block 3 is used to support a rotating lead screw 4. A rotating lead screw 4 is rotatably arranged on one side of the support block 3. The rotating lead screw 4 is used to drive a rotating gear 7 to rotate. A rotating block 5 is slidably arranged at one end of the rotating lead screw 4. The rotating block 5 is used to drive the rotating lead screw 4 to rotate. A limiting rod 6 is arranged inside the rotating block 5. The limiting rod 6 is used to limit the rotating block 5. The bottom end of the rotating lead screw 4 is meshed with a rotating gear 7. A limiting hole is arranged on one side of the support block 3. Arc-shaped threads are provided on the outer wall of the rotating lead screw 4. A cavity is arranged inside the rotating block 5, and a spring is arranged in the cavity.

[0025] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] When the coaxial busbar flange structure needs to connect a cable, the user moves the rotating block 5 to the right. The rotating block 5 drives the limiting rod 6 to move to the right. The limiting rod 6 moves to the right and disengages from the limiting hole provided on one side of the support block 3 to cancel the limitation of the rotating block 5. Then the rotating block 5 is rotated. The rotating block 5 drives the rotating lead screw 4 to rotate. The rotating lead screw 4 rotates and drives the rotating gear 7 to rotate through the arc-shaped thread provided on the outer wall. The rotating gear 7 rotates and drives the flange plate 2 provided at the bottom of the rotating gear 7 to move left and right. When the flange plate 2 is moved to a suitable position, the user moves one end of the cable to one end of the flange plate 2. Then the rotating tube 12 is rotated. The rotating tube 12 rotates and drives the push rod 11 to move back and forth through the thread provided on the inner wall of the rotating tube 12. The push rod 11 moves back and forth and drives the top end of the connecting rod 10 to move outwards. The top end of the connecting rod 10 moves outwards and drives the rotating rod 8 fixedly provided at the bottom end of the connecting rod 10 to rotate. The rotating rod 8 rotates and drives the pressing plate 9 to move left and right through the thread provided on the outer wall of one end of the rotating rod 8 and the thread provided in the through hole at the top end of the pressing plate 9. The pressing plate 9 moves left and right to fix the top end of the cable at the bottom end of the flange plate 2, which is convenient for quickly connecting the cable and the flange plate 2. At the same time, it prevents the flange plate 2 from deforming due to the hardness of the cable, so that the distance between the flange plates 2 is too close, resulting in the connection of the flange plates 2 and causing a short circuit.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention.
