Abstract

The invention relates to a connecting component, particularly to a pneumatic rotary joint. The pneumatic rotary joint comprises a rotary spindle, a joint body is coaxially connected at one end of the rotary spindle, a first vacuum gas chamber is arranged in the rotary spindle, a second vacuum gas chamber is arranged in the joint body and communicated with the first vacuum gas chamber, the rotary spindle is provided with a vacuum outlet communicated with the first vacuum gas chamber, the joint body is provided with a vacuum port communicated with the second vacuum gas chamber, an inflation spindle pipe is arranged at the axis position of the rotary spindle and the joint body, the first vacuum gas chamber and the second vacuum gas chamber evenly surround the inflation spindle pipe, and an inflation connection is fixedly arranged at one end far away from the rotary spindle on the joint body and communicated with the inflation spindle pipe. The pneumatic rotary joint has the advantages of being high in tightness, capable of guaranteeing an inflation path and a vacuum pumping path to be parallel and to surround the rotation axis evenly and the like.

Description

technical field

[0001] The invention relates to a connecting part, in particular to a rotary joint for gas. Background technique

[0002] The existing rotary mechanism needs to inflate the interior of the rotary mechanism and vacuumize it at the same time, but there is no assembly connector in the prior art, only the inflator and the vacuum pump can be connected to the rotary mechanism, and they must be connected to the rotary mechanism. Different positions easily affect the rotation of the rotating mechanism, and it cannot be guaranteed that the inflation path and the vacuuming path can be parallel and uniform around the axis of the rotating mechanism. Moreover, this connection is complicated and inconvenient for maintenance, repair and replacement. The two passages of inflation and vacuuming require high sealing performance, not only can there be no air leakage, but also the sealing and no leakage between the two passages should be ensured. Some joints are only suitable ...
