The external screw thread that internal screw thread coupled zone in male connection corresponds on the inside of nut decouples area.The male connection and nut it
Between be arranged with circlip;Flexible padded coaming between the nut and male connection;The internal screw thread solution of male connection
Coupling area is provided with cricoid back-up ring mounting groove;The male connection end is provided with gasket seal;The pipeline body is soft
Pipe or hard tube.The compatible cooperation internal and external screw thread of closestool of the present invention, having broken pipe can only be in internal screw thread or external screw thread
A certain limitation;Sealing node is reduced, joint dimension is smaller, and connection effect is beautiful.
The present invention also provides a kind of methods using internal and external threads universal joint, comprising: when needs are connected with internal screw thread
When, nut is stretched out in the internal screw thread coupled zone in male connection;Internal screw thread coupled zone in male connection is coupled with internal screw thread;
Internal screw thread decoupling area in the male connection corresponds to the external screw thread coupled zone on the inside of nut;When needs are connected with internal screw thread
When, the internal screw thread coupled zone in male connection is contracted to nut interior;External screw thread coupled zone and internal screw thread coupling on the inside of nut
It closes;The external screw thread that internal screw thread coupled zone in the male connection corresponds on the inside of nut decouples area.Male connection it is interior
Screw thread decoupling area is provided with cricoid back-up ring mounting groove;It is first that retaining ring is radially compressed when installing retaining ring, it is packed into retaining ring peace
Tankage;After male connection is packed into nut, retaining ring restores to the original state under own resilient, is mounted on retaining ring in nut.This hair
The bright compatible cooperation internal and external screw thread of the method using internal and external threads universal joint, internal screw thread can only be matched by having broken pipe
Or a certain limitation in external screw thread;Sealing node is reduced, joint dimension is smaller, and connection effect is beautiful.
The present invention provides a kind of connector, on the basis of guaranteeing that size is lesser, can not only connect with external screw thread, but also can be with
Internal screw thread connection reduces pipeline switching bring sealing risk, reduces the size of connector portions, the use of adapter is omitted.
When needing connect with external screw thread: exemplary graph 1 is original state, then rotating nut, make external screw thread coupled zone on nut with outside
Internal screw thread coupled zone screw thread couple on nipple, internal screw thread coupled zone end of the nut in male connection is mobile, directly
External screw thread coupled zone on to nut and the internal screw thread coupled zone cooperation in male connection, because of the external screw thread coupled zone on nut
It is clearance fit with the internal screw thread coupled zone in male connection, then the rotation of nut not will lead to Forward, make at this time in retaining ring
Under (such as Fig. 3), there is no axial advancements for nut.So when the external screw thread of external screw thread coupled zone and connected piece on nut is matched
When conjunction rotation is tightened, pressing force only is generated to rubber sheet gasket, sealing is guaranteed.When needing to connect with internal screw thread, shown in Fig. 1
Structure can be connected directly.Assuming that Fig. 3 is original state, then rotating nut, makes external screw thread coupled zone and the external screw thread on nut
Internal screw thread coupled zone coupling on connector, and it is mobile towards the internal screw thread coupled zone direction in male connection, when on nut
When internal threaded regions on external screw thread coupled zone and male connection couple cooperation, because of clearance fit, the rotation of nut and outer spiral shell
Line connector is no longer associated with, and is restored to Fig. 1 state at this time.When Fig. 1 state, allow the internal screw thread of connected piece relative to outer on nut
When the rotation of screw thread couple area is tightened, pressing force only is generated to rubber sheet gasket, sealing is guaranteed.When connector and external screw thread cooperate
When, nut occurs vibration and generates noise, flexible buffer structure (such as foam material or modeling between nut and male connection
Material) inhibit noise to generate.In order to facilitate the installation of retaining ring, the internal screw thread decoupling area in male connection has a groove, makes
After circlip is radially compressed, diameter is less than the minimum diameter of nut, and retaining ring slides into nut.After compression is released, retaining ring
It becomes large-sized, avoids retaining ring and deviate from from nut.The compatible cooperation internal and external screw thread of this structure, having broken pipe can only be with interior
A certain limitation in screw thread or external screw thread.
Present invention may apply to various terminals, such as water supply, draining, hydraulic conveying, gas conveying etc., and pipeline to be needed to connect
The occasion connect;It can be adapted for various pipelines, such as hose, hard tube etc.;It can be adapted for various equipment, such as closestool, bath
The various products for needing pipeline to connect such as cylinder.
The present invention is not limited to embodiments discussed above.The description of specific embodiment is intended to above in order to retouch
State and illustrate technical solution of the present invention.The obvious transformation or substitution enlightened based on the present invention should also be as being considered
Fall into protection scope of the present invention.Above specific embodiment is used to disclose best implementation method of the invention, so that this
The those of ordinary skill in field can reach of the invention using numerous embodiments of the invention and a variety of alternatives
Purpose.
