Description
Technical field
The utility model relates to a kind of link, and more particularly, it relates to a kind of link 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, 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 is lived by the gap plugging between two mouths of pipe, prevents 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 the link providing a kind of corrugated stainless steel tubing, and link can ensure that joint possesses better tightness, and joint stability is also better.
For achieving the above object, the utility model provides following technological scheme:
A kind of link 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, rubber pipe outer wall is provided with the hold-down ring of band tapering near one end of bellows, hold-down ring has large mouth and osculum, and hold-down ring osculum end is near bellows, the inner chamber of urceolus is made up of cylindrical cavity and round platform chamber, the diameter of cylindrical cavity is greater than the maximum diameter in round platform chamber, round platform chamber end is near corrugated stainless steel tubing, the tapering in round platform chamber is identical with the tapering of hold-down ring, and the inwall in round platform chamber fit with the outer wall of hold-down ring, screw thread is located at cylindrical cavity inwall.
Further, the minimum diameter in round platform chamber and the osculum equal diameters of hold-down ring.
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 minimum diameter in round platform chamber.
Further, hold-down ring outer wall is embedded with the ganoid spring sheet of at least two panels along its circumference, and the two-port of hold-down ring 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.

Embodiment
See figures.1.and.2, a kind of link of corrugated stainless steel tubing, comprise inner core 1 and urceolus 5, inner core 1 is one section of rubber pipe, one end of rubber pipe is fixedly connected with corrugated stainless steel tubing, and the concrete Placement of rubber pipe and corrugated stainless steel tubing is: one end of rubber pipe is stretched in corrugated stainless steel tubing, and rubber pipe outer wall and corrugated stainless steel tubing inwall are bonded by mighty bond, also have extrusion ring in the inside of rubber pipe, rubber pipe tightly extrudes by extrusion ring and corrugated stainless steel tubing.Be provided with the hold-down ring 2 of band tapering near one end of bellows at rubber pipe outer wall, and hold-down ring 2 osculum end is near bellows.
With reference to Fig. 3 and Fig. 4, the inner chamber of urceolus 5 is made up of cylindrical cavity 7 and round platform chamber 8, and the osculum end in round platform chamber 8 is near bellows, and round platform chamber 8 contacts with hold-down ring 2, and the tapering in round platform chamber 8 is equal with the tapering of hold-down ring 2, the osculum internal diameter in round platform chamber 8 is equal with the osculum external diameter of hold-down ring 2.Be provided with the screw thread 9 supporting with external interface at cylindrical cavity 7 inwall, be provided with nut 6 at urceolus 5 outer wall.After connecting head is connected with the outside mouth of pipe, rotating nut 6 can make urceolus 5 and inner core 1 that relative movement occurs, and after round platform chamber 8 contacts with hold-down ring 2, continues hold-down ring 2 can be made to be pressed tighter by former direction rotating nut 6.
With reference to Fig. 1, in order to not depart from hold-down ring 2 when when making to be connected and fixed, move in round platform chamber 8, be provided with limited ring 3 at rubber pipe away from one end of bellows, the external diameter of limited ring 3 is greater than the osculum internal diameter in round platform chamber 8.In addition, in order to make the intensity of rubber pipe higher, simultaneously in order to be beneficial to round platform chamber 8 at hold-down ring 2 surface sliding, the ganoid spring sheet of at least two panels 4 is embedded with at hold-down ring 2 outer wall, spring sheet 4 is uniformly distributed along the conical surface of hold-down ring 2, and the two-port of hold-down ring 2 is pointed at the two ends of spring sheet 4 respectively.
