[0046] In the actual installation process, the control knobs 7 play an auxiliary fixing role, that is, after adjusting the included angle between the two rotating units 4, pressing any control knob 7 at the two ends of the rotating shaft 51 limits the rotation of the rotating arm 52, so as to facilitate the subsequent tightening of the fastening bolt 1. By tightening the fastening bolt 1, the corner connecting part 2 and the right-angle connecting part 3 are fixed, and then the two rotating units 4 are fixed at the current angle.

[0047] In the preferred embodiment of the utility model, the two limiting blocks 6 are connected with a guide shaft 16 therebetween, the guide shaft 16 is arranged along the radial direction of the rotating shaft 51, and the limiting blocks 6 are slidingly connected to the guide shaft 16.

A toothed groove 19 is provided on the end of the control button 7 facing the bottom of the mounting hole 13. Multiple guide blocks 20 are protruding from the side wall of the pressure rod 18 and evenly distributed in the circumferential direction. A limiting strip 21 is protruding from the side wall of the control button 7. The inner wall of the mounting hole 13 has a guide rail 22.

One end of the first return spring 26 abuts against the side of the guide block 20 facing the limiting block 6, and the other end of the first return spring 26 abuts against the limiting platform 27.

[0049] When the control button 7 is pressed down, the control lever 18 rotates circumferentially along the toothed groove 19 and shifts downward. Each limiting strip 21 slides and connects to the corresponding straight groove 23 or straight hole 24. Driven by the control button 7, the guide block 20 slides along the toothed guide surface 25 into the straight hole 24 or slides into the groove opening of the straight groove 23. The guide block 20 is engaged at the groove opening of the straight groove 23 to push the limiting block 6 out from the side hole 14 into the limiting groove 15.

[0050] In a preferred embodiment of the present invention, a second return spring 28 is sleeved on the surface of the guide shaft 16, and the two ends of the second return spring 28 are respectively connected to a limiting block 6. The second return spring 28 is a tension spring.

[0051] Specifically, in this embodiment, when the pressure rod 18 is not inserted into the slot 17, the second reset spring 28 pulls the two limiting blocks 6 tight. At this time, the ends of the two limiting blocks 6 that are far apart from each other are located in the side hole 14 and do not enter the limiting groove 15.

[0052] The guide block 20 protrudes in a toothed shape at one end toward the control button 7.

[0057] When it is needed to release the limiting state of the rotating arms 52, the control knob 7 is pressed again, the guide block 20 exits the straight groove 23 and continues to rotate under the guidance of the tooth-shaped groove 19, the first reset spring 26 restores the deformation and pushes the guide block 20 into the straight hole 24, the pressing rod 18 exits the insertion slot 17, the second reset spring 28 restores the deformation, and the limiting blocks 6 are reset under the action of the second reset spring 28, so that the rotating arms 52 are released from the limiting state.

[0058] The side wall of the rotating shaft 51 is provided with a ring groove for clamping the rotating arm 52, so that the rotating arm 52 cannot move along the axis direction of the rotating shaft 51.

[0059] When the user presses the control knob 7 and finds that the control knob 7 cannot be pressed down continuously, it indicates that the limiting groove 15 on the rotating arm 52 is not aligned with the side hole 14 on the rotating shaft 51 at this time, the rotating shaft 51 needs to be rotated by the user under the premise that the rotating arm 52 is kept stationary, so that the side hole 14 is aligned with the limiting groove 15, and the control knob 7 can be continuously pressed during the rotation, because the limiting strip 21 is clamped in the guide rail 22, the control knob 7 can rotate with the rotating shaft 51, when the side hole 14 is aligned with the limiting groove 15, the control knob 7 can be pressed down smoothly, so that the limiting blocks 6 are clamped in the limiting groove 15 through the side hole 14, then the pressing rod 18 is slightly lifted, the pressing rod 18 is in the holding state, and one end of the limiting block 6 is kept clamped in the limiting groove 15.

In order to fix the dust cover, a ball head plunger can be arranged at one end of the mounting groove 29, and a clamping groove for clamping and positioning the ball head plunger is arranged on one side of the mounting rib 31, so as to avoid the accidental falling of the dust cover. The mounting step of the dust cover is after the tightening of the fastening bolt, so that the dust cover covers the fastening bolt.

[0062] In the preferred embodiment of the utility model, the side plate 42 is provided with a heat dissipation opening 32 distributed along the length direction.

[0063] Specifically, in the embodiment, the side plate 42 has a protruding part on the surface, and the heat dissipation opening 32 is arranged obliquely, that is, one end of the heat dissipation opening 32 connected to the external environment is lower than the other end connected to the internal environment, so as to reduce the probability of foreign matter invading the internal environment through the heat dissipation opening 32.

[0064] In summary, the folding angle connecting part 2 has a slot for inserting the external bus duct, and the bus duct is inserted into the slot and connected with the conductive assembly. The external shell of the bus duct and the split shell can be fixedly connected through bolts.

[0065] By adjusting the included angle between the two rotating units 4, the bus duct and the split shell after adjusting the included angle are inserted and fixed, so as to adapt to the connection of the horizontal bending section in the complex bus duct line connection layout. After adjusting the included angle between the two rotating units 4, the limiting block 6 is clamped on the rotating arm 52 by controlling the knob 7, and then the fastening bolt 1 is tightened, so as to fix the rotating unit 4 at the current angle, avoid the deviation of the rotating unit 4 in the subsequent installation and use, and make the installation structure more stable and reliable.

[0066] When the rotating unit 4 rotates around the axis of the rotating shaft 51, the folding angle connecting part 2 is fixed on the rotating unit 4, and the straight line connecting part 3 is connected with the folding angle connecting part 2 through the fastening bolt 1, so that the straight line connecting part 3 deviates towards the direction away from the rotating shaft 51 and partially exposes the rotating unit 4. After the angle adjustment is completed, a dust cover can be additionally arranged to protect the internal structure of the split shell. In addition, during power transmission, the installation structure is heated due to power consumption, and the heat dissipation opening 32 is arranged on the side plate 42 to assist heat dissipation, thereby prolonging the service life of the installation structure of the electric interlocking line standard connector.
