Flow-collecting universal rotary joint structure for multi-channel electric signal transmission

Abstract

The utility model provides a flow-collecting universal rotary joint structure for multi-channel electric signal transmission. Lead holes are formed in an upper rotating body assembly and a lower rotating body assembly; a conductive slip ring is mounted in the inner cavity of the upper rotating body assembly; a plurality of paths of signal leading-out wires I at the left end of the conductive slipring are led out from the lead hole in the upper rotating body assembly; the left end of the lower rotating body assembly is inserted into the inner cavity and connected with the right end of the conductive slip ring; a plurality of signal outgoing lines II at the right end of the conductive slip ring are led out from the lead hole in the lower rotating body assembly, the lower rotating body assembly is rotationally connected with the upper rotating body assembly through a bearing arranged in the inner cavity, and the left end of the upper rotating body assembly and the right end of the lowerrotating body assembly are connected with slings on the corresponding sides through plug pins. The flow-collecting universal rotary joint structure can freely rotate by 360 degrees, the phenomenon that wires are intertwined or broken under the condition that a hung object frequently rotates is avoided, the sling is effectively prevented from being knotted, installation is convenient and easy, thebearing capacity is high, the weight is light, reliability is high, and electric signals do not interfere with one another, are not attenuated and are not distorted in the rotating process.

Description

technical field [0001] The invention belongs to the technical field of cable joints, and in particular relates to a current-collecting universal rotary joint structure capable of transmitting multiple electrical signals. Background technique [0002] In the wire transmission, the universal rotary joint is mainly used in conjunction with the sling, which can effectively avoid the sling knotting. With the advancement of technology, some suspension systems need to transmit multiple electrical signals with the sling, and directly use the wire to transmit the electrical signal , but during use, due to the rotation of the suspended object, it is easy to cause the wires to be entangled or broken, which affects the transmission of electrical signals. In order to ensure the quality of signal transmission and avoid wire breakage, it is necessary to improve. Contents of the invention [0003] The technical problem solved by the present invention is to provide a current-collecting uni...
