Description
Technical field
The utility model belongs to helix tube terminal technical field, and in particular to a kind of composite screw with Novel sealing ring
Pipe.
Background technique
Helix tube requires installation connection terminal in end when in use, generally installs a card in the end of helix tube
Then connection terminal is caught in the end of helix tube and is fixed connection terminal by tightening nut, in order to guarantee helix tube by head
Sealing reliability between connection terminal is provided with seal washer, traditional skill between the end and connection terminal of helix tube
The seal washer of art is caught in connection terminal when in use, and the end plug-in card of helix tube in connection terminal and is then made spiral
The end of pipe is pressed on the bottom surface of gasket, although can realize that a certain extent sealing compresses, it seals stability
It is relatively limited, and since seal washer is rubber structure, so the case where being easy to appear displacement during installation, to also be difficult to
Guarantee the reliability of sealing, so applicability and practicability are restricted.
Summary of the invention
The purpose of the utility model is to provide a kind of structure setting rationally and good seal performance with Novel sealing ring
Combined helical pipe.
The technical solution for realizing the utility model aim is a kind of combined helical pipe with Novel sealing ring, including locking
Ring is supported in nut, connection end, internal screw thread limit, and the internal screw thread limit is supported ring and is threadedly coupled on the coil, the internal screw thread
The end that ring and helix tube are supported in limit is inserted into the connection end and is locked by locking nut, the helix tube with
It is provided with seal washer between connection end, is provided with internal screw thread on the inner wall of the seal washer, in the seal washer
It is provided with bulge loop at the top of inner wall, the bottom surface of the bulge loop is provided with retainer ring groove, the section of the retainer ring groove is that inclination is set
It sets and inclined big nose circle is in the top of bulge loop and tilts the bottom surface that roundlet is in bulge loop, the end thread of the helix tube connects
It connects in the seal washer and end edge is caught in the retainer ring groove.
Be provided with positioning convex ring on the inner wall of the connection end, the internal diameter of the seal washer and positioning convex ring it is interior
Diameter is identical and the internal diameter of the bulge loop is less than the internal diameter of positioning convex ring.
The thickness that ring is supported in the internal screw thread limit is identical as the thickness of seal washer, and the outer of ring is supported in internal screw thread limit
Diameter is identical as the internal diameter of connection end.
It is copper to support ring and the seal washer is rubber washer that ring is supported in internal screw thread limit.
The utility model has the effect of positive: the structure setting of the utility model is reasonable, in the seal washer used
It is provided with internal screw thread, while being additionally provided with retainer ring groove, can be threadedly coupled with helix tube, and end edge has been caught in retainer ring groove
It is interior, then by seal washer, it is more convenient not only to operate, and can effectively guarantee sealing reliability, stability in use it is good and
It is practical.
