Abstract
The utility model discloses a structure of a rotary air inlet joint. An isolating sleeve is arranged at the inner end of a right large hole of a connecting sleeve; an air outlet pipe is fixedly arranged in a connecting sleeve large hole in the right end of the isolating sleeve through two same ball bearings; a bearing cover is fixedly arranged on a right port part of the connecting sleeve by using a bolt; an H-shaped seal ring and an annular adjusting plate are arranged in a small hole in the left end of the connecting sleeve close to the end face of the isolating sleeve in sequence; a flange connector is fixedly arranged on a left port part of the connecting sleeve by using a bolt; the flange connector and the connecting sleeve are sealed by using an O-shaped seal ring; an L-shaped seal ring is arranged in an inner annular groove formed by the flange connector and the annular adjusting plate; a spring steel wire is arranged in the annular grove of the L-shaped seal ring; and inner holes of the L-shaped seal ring and the H-shaped seal ring are closely sleeved on the left end part of the air outlet pipe. The structure of the rotary air inlet joint has the advantages of flexible and reliable operation, good sealing effect, low probability of air leakage and long service life.
Description
Technical field
The utility model relates to a kind of pneumatic element, is specifically related to a kind of structure of rotating inlet joint, belongs to the pneumatic element technical field.
Background technique
The rotating inlet joint is a kind of parts that in pneumatic system, pressurized air are connected with the rotation pneumatic element, at present, although swivel joint is being not quite similar aspect structure and specifications and models,, easily leak gas after all having more or less long-time the use, the defective that working life is shorter.
Summary of the invention
The purpose of this utility model is: for the existing defects of existing rotating inlet joint, the utility model provides a kind of structure of novel rotating inlet tap points, overcomes the existing existing defects of rotating inlet joint.
the technological scheme that the above-mentioned purpose that realizes the utility model adopts is: the structure of described a kind of rotating inlet joint, it is by the flange connecting head, bolt, spring steel wire coil, the L-type seal ring, the annular regulator plate, the H RunddichtringO, separation sleeve, ball bearing, connecting sleeve, bearing cap, steam outlet pipe, dust ring, the O RunddichtringO forms, it is characterized in that: the central axis position of connecting sleeve is shaped with aperture and the macropore that the left and right communicates, the inner end of macropore arranges a separation sleeve is installed on the right of connecting sleeve, by two identical ball bearings, fixedly steam outlet pipe is installed in the connecting sleeve macropore of separation sleeve right-hand member, the rigid bearing lid is installed with bolt in right output port position at connecting sleeve, be provided with dust ring between bearing cap and steam outlet pipe, in the aperture of connecting sleeve left end, the end face of adjacent separation sleeve is disposed with H RunddichtringO and annular regulator plate, the fastening flange connecting head is installed with bolt in left port position at connecting sleeve, seal with the O RunddichtringO between described flange connecting head and connecting sleeve, in by flange connecting head and the formed interior circular groove of annular regulator plate, the L-type seal ring is set, the sectional shape of described L-type seal ring is " L " shape, in the circular groove of L-type seal ring, spring steel wire coil is set, all L-type ring inner holes with all closely be socketed in the left part of steam outlet pipe with H RunddichtringO endoporus.
Beneficial effect: the utility model is due to after adopting said method, and the utility model not only has and goes slick reliably, and especially sealing effect is better, is difficult for long advantage of gas leakage, working life.
