Power supply support for rotatably connecting

Abstract

The invention discloses a power supply support for rotatably connecting. The power supply support comprises a sliding ring, a support arm and a wiring terminal, wherein the support arm and the slidingring are integrally formed, the support arm is fixedly connected to an outer wall of the sliding ring, the support arm and the sliding ring both are conductors, a liquid accumulation cavity is formedin the support arm, one end of the liquid accumulation cavity extends to a sliding direction and penetrates through a wall of the sliding ring, an opening is formed in an inner wall of the sliding ring, a conductive liquid is arranged in the liquid accumulation cavity, and the wiring terminal is arranged on the support arm and is used for connecting a power supply; and when the sliding ring sleeves a rolling body, the inner wall of the sliding ring is in contact with a surface of the rolling body and can rotate relative to the surface of the rolling body, the conductive liquid in the liquid accumulation cavity flows out of the opening of the liquid accumulation cavity and is in contact with the surface of the rolling body, and the power supply is used for supplying power to the rolling body in a rotating state by the sliding ring and the conductive liquid. By the power supply support, the problem of power supply difficulty of the rolling body in the rotating state can be solved.

Description

technical field [0001] The invention relates to the field of movable power supply, in particular to a power supply bracket for rotating connection. Background technique [0002] Install a rolling body on the bracket, insert the rolling body into the mounting hole on the bracket, and make the rolling body rotate in the mounting hole on the bracket; when the rolling body needs to supply power to the rolling body during the rotation, many difficulties will arise; first , the wire cannot be fixedly connected directly to the rolling body. If the guide is directly connected to the rolling body, the rolling body will knot the wire during the rotation process, and the wire will also affect the rotation of the rolling body; if the wire is connected to the bracket, The power supply is supplied through contact between the mounting hole on the bracket and the contact surface of the rolling body. If the rolling body and the inner wall of the mounting hole are worn during the rotation, th...
