A pipe fitting structure combining quick connection and threaded connection, consisting of a joint body, at least one quick connection end and a sealing gasket, wherein the joint body provides at least one threaded interface connected to an external pipeline, and the quick connection end consists of a joint body, a lock The locking screw sleeve, the inner ferrule and the sealing ring are formed, the locking screw sleeve is set outside the inner liner pipe on the joint body, and the locking screw sleeve is connected with the thread at the root of the inner liner pipe on the joint body through threads. The inner ferrule is set outside the circumference of the front section of the inner liner on the joint body, and the front end of the outer wall of the inner ferrule is provided with a conical surface, and the external connecting pipe is inserted from the front end of the locking screw sleeve to the inner peripheral wall of the inner ferrule and the joint body Between the outer circumferences of the front section of the lining pipe on the top, the inner wall of the middle section of the locking screw sleeve is provided with a conical surface. The present invention utilizes the deformation of the inner ferrule arranged in the locking screw sleeve to lock the external connecting pipe to realize the quick connection between the external connecting pipe and the joint body, and utilizes the threaded interface provided on the joint body to realize the connection with the external thread, thereby A pipe fitting structure combining quick connection and threaded connection is realized.
Description
Technical field: [0001] The invention relates to pipeline transportation technology, in particular to pipeline connectors, in particular to a combined quick-connect and threaded-connection pipe structure. Background technique: [0002] In the prior art, water pipe joints are often used to connect two external connecting pipes. The external connecting pipes may have different connection methods. The quick-connect pipe joint adopts the structure of two conical surfaces extruding each other. In order to achieve reliable sealing and connection, the conical It is necessary to maintain a large pressure between the surfaces, which may easily cause the nut with the inner conical surface, or the connected straight pipe, or the outer conical surface member to rupture. In addition, in many occasions, external appliances need to provide connecting pipe fittings with threaded structures, and the quick-connect pipe joints in the prior art cannot be connected with threaded pipe fittings. ...
