Be equipped with direction mouthful in the link of rubber tube, the back is connected to connector and the outside mouth of pipe, twists to move the nut and can make the rubber tube extrudeed tightlyer, and the gas tightness is with regard to better.
Description
Technical field
The utility model relates to a kind of link, and more particularly, it relates to a kind of connecting head of corrugated stainless steel tubing.
Background technique
Corrugated stainless steel tubing is installed in liquid or gas delivery system as a kind of flexible pressure-resistant pipe fitting, in order to compensate the mutual displacement of pipeline or machine, equipment connection end, absorbing vibrational energy, the effect such as vibration damping, noise reduction can be played, have flexible, quality is light, corrosion-resistant, the multinomial feature such as antifatigue, high-low temperature resistant.
Small diameter metal flexible pipe generally adopts fast connector to connect, connecting head comprises inner core and urceolus, usually seal ring is housed in connecting head, when two metal pipe mouth are communicated with by connecting head, seal ring is by two mouth of pipe extrusion-deformations, and then the gap plugging between two mouths of pipe is lived, prevent gas or liquid from overflowing from this gap.
But when encountering connecting head after a long time use or because of carelessness, connecting head may be made to loosen, the extruding force that seal ring is subject to reduces, thus makes tightness be deteriorated.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is a kind of connecting head of corrugated stainless steel tubing, and the tightness of this connecting head is better, and joint not easily loosens.
For achieving the above object, the utility model provides following technological scheme:
A kind of connecting head of corrugated stainless steel tubing, comprise inner core and urceolus, the screw thread supporting with external interface is provided with at outer tube inner wall, drum outer wall is provided with nut outside, inner core is one section of rubber pipe, one end of rubber pipe is fixedly connected with corrugated stainless steel tubing, the inwall of the other end of rubber pipe is with tapering, and the diameter of this section of inwall reduces gradually towards the direction of corrugated stainless steel tubing, the inner chamber of urceolus is by the first cylindrical cavity, second cylindrical cavity and round platform chamber are formed, round platform chamber has large mouth and osculum, and the osculum in round platform chamber is near corrugated stainless steel tubing, first cylindrical cavity is positioned at the great Kou side in round platform chamber, and the large mouth equal diameters in the diameter of the first cylindrical cavity and round platform chamber, second cylindrical cavity is positioned at the osculum side in round platform chamber, and the osculum equal diameters in the diameter of the second cylindrical cavity and round platform chamber, the osculum diameter in round platform chamber is less than the external diameter of rubber pipe, screw thread is located at the inwall of the first cylindrical cavity.
Further, rubber pipe is provided with limited ring away from one end of corrugated stainless steel tubing, and the external diameter of limited ring is greater than the osculum internal diameter in round platform chamber.
Further, the outer wall of rubber pipe is embedded with the ganoid spring sheet of at least two panels along its circumference, and the two-port of rubber pipe is pointed at the two ends of spring sheet respectively.
Compared with prior art, the utility model has the advantages that: be different from traditional connecting head and obtain tightness by two mouth of pipe crush seal rings, the utility model obtains tightness by outer tube inner wall and external connecting pipe outer wall extruding rubber pipe, this method is more reliable, and urceolus is twisted tighter, tightness is higher.
Accompanying drawing explanation

Fig. 2 is the outside schematic diagram of urceolus;
Fig. 3 is the sectional view of urceolus;
The sectional view of Fig. 4 position connecting head.
Description of symbols: 1, inner core; 2, limited ring; 3, spring sheet; 4, urceolus; 5, nut; 6, the first cylindrical cavity; 7, round platform chamber; 8, the second cylindrical cavity; 9, screw thread.
Embodiment
A kind of connecting head of corrugated stainless steel tubing, comprise inner core 1 and urceolus 4, the screw thread 9 supporting with external interface is provided with at urceolus 4 inwall, nut 5 is provided with at urceolus 4 outer wall, inner core 1 is one section of rubber pipe, one end of rubber pipe is fixedly connected with corrugated stainless steel tubing, the inwall of the other end of rubber pipe is with tapering, and the diameter of this section of inwall reduces gradually towards the direction of corrugated stainless steel tubing, the inner chamber of urceolus 4 is by the first cylindrical cavity 6, second cylindrical cavity 8 and round platform chamber 7 are formed, round platform chamber 7 has large mouth and osculum, and the osculum in round platform chamber 7 is near corrugated stainless steel tubing, first cylindrical cavity 6 is positioned at the great Kou side in round platform chamber 7, and the large mouth equal diameters in the diameter of the first cylindrical cavity 6 and round platform chamber 7, second cylindrical cavity 8 is positioned at the osculum side in round platform chamber 7, and the diameter of the second cylindrical cavity 8 and the osculum equal diameters in round platform chamber 7, the osculum diameter in round platform chamber 7 is less than the external diameter of rubber pipe, screw thread 9 is located at the inwall of the first cylindrical cavity 6.One end inwall be connected with external interface due to rubber pipe has tapering, and this length of tape has one end interface towards the outside that the inner diameter of tapering is large, convenient laborsaving when can make insertion external interface like this.After external interface enters rubber pipe, by the screw thread 9 of urceolus 4 and the screw thread 9 of external interface to it, turn nut 5, external interface is made more to go deep into rubber pipe, when external interface arrives the position in round platform chamber 7, round platform chamber 7 inwall and external interface inwall extrude rubber pipe, and rubber pipe inwall and external interface outer wall are sealed, and nut 5 is twisted more tightening seal is better.
In order to prevent urceolus 4 and rubber pipe from departing from, be provided with limited ring 2 at rubber pipe away from one end of corrugated stainless steel tubing, the external diameter of limited ring 2 is greater than the osculum internal diameter in round platform chamber 7.
