Abstract
The utility model relates to a spiral telescopic joint which comprises a spiral telescopic joint body, wherein a bulged step is arranged on the lower part of the inner side of a spiral port of the spiral telescopic joint body, a rubber sealing ring is arranged on the upper end surface of the step, the bottom end of the rubber sealing ring is provided with an inverted V-shaped groove, and the upper end surface of the rubber sealing ring is provided with a pressure ring; the spiral telescopic joint body, the rubber sealing ring and the pressure ring form a spiral telescopic joint assembly, the spiral telescopic joint assembly is fixed by a spiral telescopic joint nut, and an annular pressing platen is arranged on the inner side of the top end of the spiral telescopic joint nut. The spiral telescopic joint disclosed by the utility model has the advantages that the deformation of the rubber sealing ring is greatly increased as the pressure ring is additionally arranged at the contact part between the telescopic joint nut of the conventional telescopic joint and the rubber sealing ring, thus the sealing property of the whole spiral telescopic joint is enhanced and the sealing property of a pipeline system is enhanced.
Description
Technical field
The utility model relates to a kind of spiral expanding joint.
Background technique
Spiral expanding joint in the market is generally comprised of spiral expanding abridged edition body, rubber seal and spiral expanding joint nut, the rotary squeezing rubber seal that this spiral expanding joint mainly saves nut and spiral expanding abridged edition body by spiral expanding guarantees its sealing, this spiral expanding joint has the following disadvantages: the one, and larger to the dependence of rubber seal, long-term use, aging and the softening sealing effect that causes gradually of rubber seal is bad, causes leaking.
Model utility content
The purpose of this utility model is to provide a kind of spiral expanding joint, to overcome prior art above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of spiral expanding joint, comprise spiral expanding abridged edition body, described spiral expanding abridged edition body threaded port lower inside is provided with protruding step, the upper-end surface of described step is provided with rubber seal, the upper-end surface of described rubber seal is provided with pressure ring, described spiral expanding abridged edition body, rubber seal and pressure ring form spiral expanding joint assembly, and described spiral expanding joint assembly can save nut by spiral expanding and fix.
Further, the bottom of described rubber seal can be provided with reverse V-shaped groove, the inner side of the corresponding rubber seal of inner side edge of described reverse V-shaped groove.
Further, inside the open-topped place of described spiral expanding joint nut, being provided with annular presents a theatrical performance as the last item on a programme.
The beneficial effects of the utility model are: this spiral expanding joint increases a pressure ring by the slip joint nut at conventional slip joint and rubber seal contacting point, rubber seal bottom is provided with reverse V-shaped groove simultaneously, greatly strengthened the amount of deformation of rubber seal, thereby strengthened the sealing of whole spiral expanding joint, strengthened the sealing of pipe-line system.
