Description

Push-in joint
Technical field
The utility model relates to and is used for liquid, the tracheae joint of connection fast, and particularly the jointing of automobile system system tracheae belongs to the pipe joint technical field.
Background technique
Often run into the problem of connection in the pipeline of various gas transmissions, oil transportation, conduit pipe, at present,, can be approved that the rapid pipe joint of using morely is grafting screw threads for fastening joint by most of people though the pipe joint that connects is a lot of fast.This joint mainly is to have the tubular shell and the nut of band tapering in hexagonal, screw thread, the mouth of pipe to constitute by outer wall, need during use to add metal liner in the pipe end with connecting tube earlier, the added metal Taper Pipe is fixed, pipe end with connecting tube inserts in the mouth of pipe of housing band tapering then, the mouth of pipe coupling of metal Taper Pipe and housing band tapering screws with the outside thread on nut and the housing again.The other end of housing is connected with equipment by screw thread again.Existing this grafting screw threads for fastening joint needs earlier the pipe end of connecting tube to be handled, and is not easy to site operation, and need fix by tightening nut, often occur owing to nut fastening force deficiency, and it is bad that sealing takes place, workload is still very big in addition.
The model utility content
The purpose of this utility model is exactly to improve at the deficiency that existing rapid pipe joint exists, and a kind of push-in joint rapid, good sealing effect that connects is provided.
The purpose of this utility model is achieved in that push-in joint, comprises the threaded tubular shell of outer wall, it is characterized in that being provided with lock sleeve, and the lock sleeve sleeve is in housing; Described housing is made of outer tube and the conduit that is fixed in outer tube one end, and the outer tube wall in the conduit outside is provided with tapered sleeve and location ring recess, conduit and corresponding the communicating of outer tube the other end pore; Described lock sleeve in a tubular form, an end is the pipe that has back-up ring, the other end is to have the chuck that awl round platform, tube wall have axial elastic trough, the chuck outside is provided with spring ring, the inboard is provided with fore shaft.
The external diameter of described awl round platform is greater than outer tube diameter, less than location ring recess internal diameter.Outer tube wall is provided with seal ring, and seal ring is inlaid in the ring recess that is provided with on the inwall.The inwall that locking is with an end of back-up ring is provided with seal ring, and seal ring is inlaid in the ring recess that is provided with on the inwall.Be provided with seal ring between lock sleeve back-up ring and the outer tube.Fore shaft is the circle ridge.
Housing is two relative separate piece with lock sleeve, the chuck sleeve of lock sleeve in housing, the awl round platform place the location ring recess since the awl round platform external diameter greater than outer tube diameter, lock sleeve is fastened in the housing.When adopting this push-in joint to manage connection, only lock sleeve need be exerted pressure in housing from the back-up ring end, make chuck press to tapered sleeve and open, connecting tube directly is inserted on the conduit in lock sleeve, cancel pressure to back-up ring, chuck slides tapered sleeve, and connecting tube is tightly pushed down on the circle ridge of chuck inboard, makes the locking of connecting tube and conduit.The seal ring sealing is all arranged between connecting tube and outer tube, the lock sleeve and between lock sleeve and the outer tube, joint sealing is effective, aneroid, gas leakage phenomenon, between lock sleeve and the outer tube seal ring is set, can prevent external force collision compression lock sleeve, influence the locking of lock sleeve, also prevent that dust, foreign material from polluting the outer mouth of pipe of sleeve lock sleeve simultaneously connecting tube.
When the dismounting connecting tube connects, only lock sleeve need be exerted pressure in housing from the back-up ring end, make chuck press to tapered sleeve and open, connecting tube is directly extracted in lock sleeve.If lock sleeve is taken out in housing, only need firmly back-up ring to be pulled outwardly, the awl round platform easily just can be extracted in outer tube because the effect of awl circle is arranged.The lock sleeve and the housing of the push-in joint of the good connecting tube of socket connection can not separate, and guarantee the reliability that the connecting tube joint connects.
The utility model compactness rational in infrastructure is manufactured easily good integrity, appearance looks elegant.Use fast, convenient, quality of connection is good, can be used for pipelines such as various tracheaes, water pipe, oil pipe and connects, and reduces labor intensity, increases work efficiency, and the tracheae that is specially adapted to brake system of car connects.
