For example, when used in a multi-head (such as 3-head / 4-head / multi-head) lamp chandelier, multiple retractable wheels are required, resulting in a complex structure and requiring a larger installation space. In addition, the power cord needs to be separately led out from the wall seat to connect the lamp head, which looks ugly and may be interfered with when the wire is extended and retracted. Utility Model Content
[0003] The utility model aims to provide a conductive multi-line balanced telescopic wheel, which can realize multi-line telescopic of one wheel and enable each group to realize the conductive effect at the same time.
[0004] The utility model provides the following technical solution: a conductive multi-wire balanced telescopic wheel, comprising:

[0006] The wire take-up wheel is arranged in the wire take-up and stretching disc and is connected to the output end of the motor. The circumferential edge of the wire take-up wheel is provided with wire receiving grooves for winding the wires, the number of which is the same as that of the U-shaped groove wire bearings. Each wire passing through the U-shaped groove wire bearing is fixedly connected to the corresponding wire receiving groove. When the motor drives the wire take-up wheel to rotate, the wires will form a disc-like winding to realize wire take-up and stretching.
[0007] Conductive components, the conductive components include a brush PCB substrate and a brush PCB + shrapnel, the brush PCB substrate and the brush PCB + shrapnel are arranged at the bottom of the take-up wheel, and the wires are welded to the brush PCB + shrapnel. When the motor drives the brush PCB + shrapnel to rotate, the brush PCB substrate is fixed on the take-up wheel housing, and the brush PCB + shrapnel will contact with multiple brush shrapnel on the brush PCB substrate to achieve electrical conduction;
[0008] Among them, an induction wire fixing plate is arranged on the take-up wheel at one end away from the brush PCB board + spring sheet, and a spiral plane groove is formed on the surface of the induction wire fixing plate. A rolling steel ball is placed in the spiral plane groove and rolls from the A end of the spiral plane groove to the B end of the spiral plane groove. The A end and the B end have induction spring sheets electrically connected to the motor.
[0009] A further solution is that the number of turns of the spiral plane groove is consistent with the number of winding coils.
[0010] A further solution is that the retractable wire disc is provided with a telescopic wheel cover, and the telescopic wheel cover is provided with a steel ball shrapnel for pressing the rolling steel ball.

Conversely, when the motor rotates forward, the rolling steel ball will run from the initial induction spring B end to the induction spring A end, when the rolling steel ball contacts the induction spring A end, it will give a signal to stop the motor from working, that is, stop extending the wire.
[0020] 4. It can increase the motor torque, reduce resistance and noise: add anti-friction steel balls to the take-up wheel and the take-up wheel shell to prevent the take-up wheel from contacting the take-up wheel shell and reduce friction.
