Abstract

The invention provides a swivel joint, which comprises an input assembly, an output component which can rotate with respect to the input assembly, a spindle and a sealing element. The input assembly comprises input components which are provided with a socket hole, and an output hole is arranged on the output component. The number of the input components is at least two. The input components are rotatably sleeved on the rotating shaft, and at least two input components are axially arranged in parallel along the spindle. Inner walls of the at least two input components, an outer wall of the spindle and the sealing element together form a ring channel communicated with the socket hole. A feed hole for communicating the channel with the output hole of the output component is arranged in the spindle. The number of the feed hole and the output hole is corresponding to the number of the input components. Each feed hole has an opening on the spindle hole. Each opening is communicated with a corresponding input component channel. Openings of the plurality of feed holes are axially distributed at interval along the spindle. The invention further provides a rotating table using the swivel joint.

Description

technical field [0001] The invention relates to a rotary joint, in particular to a rotary joint for connecting pipelines and a rotary worktable using the rotary joint. Background technique [0002] A rotary workbench comprises a base, a turntable set on the base, a work station set on the turntable, a supply pipeline and a rotary joint set on the supply pipeline. The supply pipeline is connected to the workstation and external fluid supply sources such as gas or liquid to maintain the normal operation of the workstation. The rotary joint includes an input piece and an output piece. An output hole is opened on the output piece, and an input hole is opened on the input piece. The output piece is rotatably mounted on the input piece. The input hole and the output hole can also be kept in communication when the rotary joint rotates. In this way, when the turntable rotates, The fluid supply source can also continuously supply liquid or gas to the workstation to maintain the nor...
