Abstract
The utility model relates to a simple pin joint. A connecting thread is mounted inside a straight-through hole formed in the first end of an outer tube. The peripheral surface of the second end of the outer tube is a convex spherical surface. Connecting through holes are formed in the inside of a connecting seat. A connecting spherical belt is mounted inside a connecting through hole formed in the first end of the connecting seat. The connecting spherical belt is matched with the convex spherical surface of the second end of the outer tube in a contacting mode. A connecting internal thread is mounted inside a connecting through hole formed in the second end of the connecting seat. A connecting external thread is arranged on an excircle on the first end of a shell. The connecting external thread is in threaded connection with the connecting internal thread of the connecting seat. Through holes are formed inside the shell. A shell spherical belt is arranged inside a through hole formed in the first end of the shell. The shell spherical belt is matched with the convex spherical surface of the second end of the outer tube in a contacting mode. A connecting thread is arranged inside a through hole formed in the second end of the shell. The simple pin joint is ingenious and simple in design and structure, fewer in components, convenient to manufacture and assemble, low in cost, reliable in sealing performance and simple and convenient to use and maintain.
Description
Technical field
The utility model relates to a kind of simple and easy articulated joint, belongs to the pipeline sealing device technical field.
Background technique
Articulation rotary joint is that flowing medium is input to from static pipeline the connection sealed member that goes rotation/rocking apparatus, be solve mechanical motion connect in the run, drip, leak problem, energy saving, protection of the environment, the seal arrangement that improves working conditions.In prior art, articulation rotary joint mainly adopts axle to be loaded in housing, and lubricating cup is housed on housing, between housing and axle, combined seal ring is housed, the many component of two rows of steel balls raceway etc.Structure in swinging pipeline connection use is still more complicated for only needing, and use and maintenance is installed inconvenience, and manufacture cost is still higher.
