It sets in first axle hole section, further includes sealing bulb by annular cushion cap connection between first axle hole section and the second axis hole section, it is close
Blocking head is locked on annular cushion cap by screw, and the rear end of the rotary joint is provided with loudspeaker corresponding with sealing bulb
Mouthful.
As a kind of preferred embodiment of the utility model, the second axis hole section is formed close to one end of the sealing bulb
Circular orientation seat, the sealing bulb correspond to circular orientation seat and are provided with annular flange, and annular flange is inlaid in circular orientation seat
On.
As a kind of preferred embodiment of the utility model, one end of the nearly annular cushion cap of the ball sealer head rest is equipped with ring
Shape receiving channel, further includes red copper gasket, and red copper gasket is inlaid in annular receiving channel and is resisted against on annular cushion cap.
As a kind of preferred embodiment of the utility model, the screw is multiple, the axis of the screw and the axis hole
It is arranged in parallel, is equipped with the screw hole with the screw fit in the position that the transit joint corresponds to the annular cushion cap.
After the technical solution of the utility model, using combination sealing, the matching trim built in transit joint is done
At spherical surface, the rear molding inner sealing face of rotary joint is made into loudspeaker sealing surface, in this way when being threadedly coupled, the loudspeaker of rotary joint
Ball face sealing face built in mouth and transit joint can play automatic aligning sealing during screwing, it is therefore prevented that because installation is together
Axis degree is inadequate, causes to leak, and improves sealing performance, by screw locking between transit joint and sealing bulb, therefore can be with
According to different sealing mediums come the medium of fast sealing bulb.The utility model cooperates loudspeaker face by spherical surface, realizes certainly
It is dynamic to adjust Seal Design, can adjust automatically sealing surface reach sealing effect, seal form realize by seal with screwed joint and
The multi-sealed effect of ball face sealing, keeps sealing effect relatively reliable.
