Abstract
The invention discloses a structure of a rotary air inlet connector. A spacer ring is produced inside a middle hole of a combined body; an air outlet pipe joint is arranged in an inner hole of the combined body at the right edge of the spacer ring through a bearing; a right end cover is fixedly arranged at the part of a right port of the combined body through a bolt; an L-shaped seal ring is arranged inside the inner hole of the combined body at the left edge of the spacer ring; the side of a large circle of the L-shaped seal ring is tightly adhered to the left end face of the spacer ring; the inner hole of the L-shaped seal ring is sleeved on the excircle at the left end of an air outlet pipe; a spring ring is sleeved inside an annular groove of the L-shaped seal ring; a left end cover is fixedly arranged at the part of a left port of the combined body by the bolt; the external middle part of the left end cover is fixedly connected with an air inlet pipe joint; and an annular pressure plate is arranged between the left end cover and the L-shaped seal ring. The structure of the rotary air inlet connector has the advantages of good sealing effect and does not leak air after working for a long period of time.
Description
Technical field
The present invention relates to a kind of pneumatic element, be specifically related to a kind of structure of swivel joint, belong to the pneumatic element technical field.
Background technique
In pneumatic system, the pressurized air that leads to rotary component generally will have swivel joint to be connected with rotary component, although existing swivel joint specifications and models are more various, and, generally have the easily defective of gas leakage of structure.
Summary of the invention
The object of the invention is to: have the easily defective of gas leakage for existing rotating inlet joint, the invention provides a kind of structure of novel rotating inlet joint, overcome the defective of the existing existing easy gas leakage of rotating inlet joint.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: the structure of described a kind of rotating inlet joint: it is by the suction tude joint, annular pressing plate, left end cap, the L-type seal ring, spring ring, bearing, combination, right end cap, bolt, dust ring, the steam outlet pipe joint, O-ring seal forms, it is characterized in that: described combination medial axis position has through hole, in the intermediate hole of combination, be shaped with spacer ring, two parts that described spacer ring communicates about being divided in connection with the through hole in the middle of the body, in the combination endoporus on spacer ring the right, by bearing the steam outlet pipe joint is installed, right output port position at combination installs and fixes right end cap with bolt, in the middle of right end cap and steam outlet pipe joint, be provided with dust ring, in the combination endoporus on the spacer ring left side, be provided with the L-type seal ring, its middle sectional shape of described L-type seal ring is symmetrical L-type, the left side of spacer ring is close in L-type seal ring great circle side, the inner hole sleeve of L-type seal ring is connected on the cylindrical of steam outlet pipe left end, in L-type seal ring annular groove, be socketed with spring ring, left port position at combination is mounted with left end cap with bolt, the outside middle of described left end cap is connected and fixed with the suction tude joint, seal with O-ring seal between described left end cap and the combination, between left end cap and L-type seal ring, be provided with annular pressing plate, closely be pressed together between annular pressing plate and left end cap and the L-type seal ring.
Beneficial effect: the present invention adopts the L-type seal ring owing to be flexibly connected the position, and simultaneously, spring ring compresses seal ring and movable position all the time, so the present invention has preferably advantage of sealing effect, working long hours is difficult for the advantage of gas leakage.
